    JORDAN, Circuit Judge.
    I.    Introduction
    When asked why he was so intent on scaling Mount
    Everest, the ill-fated mountaineer George Mallory famously
    replied: “because it’s there.”1 The parties before us have put
    a twist on that philosophy: they have created their own
    mountain of issues and have argued, appealed, and cross-
    appealed nearly all of them.2 Unfortunately, if there had been
    a hope of bringing this matter to conclusion any time soon,
    that was dashed when, in the middle of trial, the District
    Court erroneously granted judgment as a matter of law
    against one side, tainting the entire trial and the ultimate
    verdict. We will therefore vacate the judgment of the District
    Court and remand with instructions for further proceedings.
    We do not take this step lightly, but the error of the District
    Court here was of such magnitude that we seriously doubt the
    correctness of the ultimate verdict.
    This case arises from the fractured relationship
    between a large communications equipment manufacturer,

    The District Court recognized the battle-every-issue
    character of the litigation. To one request from counsel to
    “make a record” of his objection, the Court responded: “Make
    a record, go ahead. The circuit will love it. It will be the
    5,927th error you have pointed out to them.” (J.A. 2397.)
    6
    Avaya Inc. (“Avaya”), and one of its dealers and service
    providers, TLI.3 After they fell out, Avaya aggressively acted
    to block TLI from providing independent maintenance
    services for Avaya equipment.            Meanwhile, the now-
    independent TLI took a series of legally dubious actions to
    gain access to Avaya communications systems used by clients
    the parties once shared. Avaya filed suit, alleging several
    business torts and breach of contract; TLI counter-sued for
    antitrust violations. After years of pre-trial litigation, and in
    the midst of a months-long trial, the District Court granted
    TLI’s motion under Federal Rule of Civil Procedure 50 for
    judgment as a matter of law against Avaya on all of Avaya’s
    affirmative claims. The Court later instructed the jury that
    none of TLI’s actions could be considered unlawful. With
    that instruction guiding it, the jury found Avaya liable for two
    antitrust violations and awarded substantial damages.
    We conclude that the entry of judgment as a matter of
    law was erroneous. Given how intertwined the two sides’
    claims are – and given that Avaya’s antitrust defense relied in
    large part on justifying Avaya’s conduct as a response to
    TLI’s conduct – we also conclude that the erroneous Rule 50

    We use “TLI” as shorthand for a group of small
    service providers that are under common ownership and
    control and are collectively the appellees/cross-appellants.
    They include Telecom Labs, Inc. (“TLI”), TeamTLI.com
    Corp., and Continuant, Inc., along with their common owners
    and managers Douglas Graham, Scott Graham, and Bruce
    Shelby. Although Continuant seemingly took over the
    businesses’ continuing interests beginning in 2005, TLI was
    the firm most involved in this dispute from the beginning, so
    we use that name for simplicity.
    7
    judgment infected the jury’s verdict. We must therefore
    vacate the judgment of the District Court. A tour of the
    mountain follows.
    II.    Background
    A.     Factual Background
    Avaya, the appellant and cross-appellee, “designs,
    manufactures, sells, and maintains telecommunications
    equipment.” (Opening Br. at 7.) Two of its products in
    particular are the subject of this suit. The first is its private
    branch exchange (“PBX”), which “is essentially a special-
    purpose computer ... that functions as a telephone
    switchboard” and is used by “[l]arge organizations needing an
    internal telephone network.” (Id.) The second product is its
    predictive dialing system (“PDS”), which is an “automated
    telephone dialing system that uses a predictive algorithm to
    anticipate when the user ... will be able to reach someone,
    improving the chances a call will be answered.” (Id. at 7-8.)
    The PBX technology was invented in the 1980s by AT&T
    Co., which in 1996 spun its PBX business off to Lucent
    Technologies, Inc., which in turn spun off Avaya in 2000.
    TLI and three individuals who operated it are the
    appellees and cross-appellants. TLI sold post-warranty
    maintenance for Avaya PBXs and PDSs. At one point, TLI
    was also part of Avaya’s Business Partner program, selling
    communications systems on Avaya’s behalf. When Avaya
    began downsizing from 1999 to 2001, it encouraged its
    Business Partners to hire laid-off Avaya maintenance
    technicians, even subsidizing that process. TLI made several
    such hires and began to offer maintenance services in 2001.
    8
    Not long after, in 2003, TLI and Avaya acrimoniously
    severed their relationship,4 but TLI continued to provide
    maintenance services on Avaya products as an independent
    service provider.
    1.     PBX Systems and Maintenance
    Of the two types of systems at issue in this litigation,
    the PBX has a substantially larger market.              Avaya
    characterizes PBX systems as durable goods with extended
    longevity and high fixed costs. During much of the time
    relevant to this suit, PBX systems had a useful lifespan of
    about eight years, though some could remain in use for
    decades.5 They have many capabilities but were sold in a
    4
    The reasons for the divorce are, of course, like
    everything else in this case, hotly contested, and they are
    elaborated in more detail below. Here is a thumbnail sketch:
    Avaya contends that TLI violated its obligations as an Avaya
    agent, whereas TLI alleges that Avaya imposed onerous
    surprise conditions to prevent a partner firm like TLI from
    recouping the investments it had made at Avaya’s request.
    5
    Those statistics are based on PBXs sold before 2000.
    In the 2000s, traditional PBXs were replaced with systems
    that use internet protocol telephony. Whereas with older
    “refrigerator-box-type PBXs, it was ... easy to identify and
    define what a ... life of a system was,” with the “IP PBXs ...
    any one server might come out of service, perhaps as quickly
    as after just a couple ... years.” (J.A. 4382.) Given the
    constant replacement of equipment on those modern PBXs, it
    is “very difficult to measure” what the lifetime of a system is.
    (Id.)
    9
    default mode without most of them activated. Customers
    could then license individual capabilities, depending on their
    needs. As one Avaya systems engineer explained it at trial,
    Avaya “provide[s] software to our customers that’s able to do
    a vast number of things, but customers don’t want to pay for
    all the things the software can do. ... They may not need all
    the capabilities ... . So we allow customers to purchase the
    right to use aspects of the software ... .” (J.A. 1886.)
    One of those “aspects” is a set of maintenance
    features6 that was and is licensed separately from the PBX
    system itself. Those features are accessed via on-demand
    maintenance commands (“ODMCs”).              Users of the
    maintenance features – whether Avaya technicians, non-
    Avaya technicians, or customers themselves – access the
    pertinent software using login credentials. Each login is
    matched to the ODMCs that that specific user is authorized to
    use. In addition to controlling those logins, Avaya has a
    second way to regulate access to the ODMCs. The ODMCs
    are only useable on a given PBX system if Avaya has
    activated the corresponding maintenance software
    permissions (“MSPs”). Avaya’s PBX systems come with the
    MSPs disabled, but customers who execute a specific license
    agreement can have the MSPs, and hence the ODMCs,
    6
    The use of the word “feature” to describe elements of
    the software that enabled remote maintenance is legally
    relevant to questions of contract interpretation in this case.
    See infra Part II.A.2. We use the word here as a generic term,
    without implying anything about how it should be read in the
    specific context of Avaya’s contracts with its customers.
    10
    enabled. Later, when that license terminates, Avaya disables
    the MSPs.
    Avaya and its authorized Business Partners offer
    maintenance service, which is a profitable line of business.
    Avaya contends that the “margin on the initial sale of a PBX
    is ‘thin,’” whereas the rate of profit on maintenance work is
    much higher. (Opening Br. at 8.) It says that the profit the
    company earns from maintenance is an important source of
    funds for the improvement of PBX systems and the
    development of new models, which are released roughly
    every two years. According to Avaya, its major competitors
    in this market – Cisco, Siemens, and Microsoft – follow a
    similar business model of low-margin equipment and high-
    margin maintenance, and those firms compete with each other
    and with Avaya over the “total cost of ownership” of both
    equipment and maintenance. (Opening Br. at 9.)
    During the time period covered by this litigation,
    Avaya offered three tiers of maintenance options for PBX
    customers. The highest-end, most expensive option was to
    buy maintenance from Avaya itself, whose technicians had
    full access to ODMCs and certain other Avaya software
    capabilities.
    The second, intermediate, option was to purchase
    maintenance from an authorized Avaya Business Partner.
    Business Partners could access a customer’s maintenance
    software through a login called “DADMIN,” once Avaya
    activated it on a customer’s PBX. As participants in Avaya’s
    maintenance program, Business Partners had to complete
    special training and were given access to engineering support.
    They also had to agree not to solicit maintenance contracts
    11
    from existing Avaya maintenance customers.               Avaya
    forthrightly admits that it thus imposed vertical restraints on
    maintenance through the Business Partner program to
    encourage the Business Partners to “expand sales of Avaya
    PBXs in the competitive primary market, rather than simply
    to cannibalize existing maintenance business.” (Opening Br.
    at 13.)
    Finally, Avaya offered a self-maintenance option to its
    customers. Prior to 2008, customers who undertook to
    maintain their own PBX systems would have to purchase a
    license to gain access to the necessary MSPs. In 2005, out of
    tens of thousands of Avaya PBX customers, about 270 of
    Avaya’s largest customers used the self-maintenance option,
    which allowed their in-house technology departments to
    perform maintenance on their PBX systems. With its 2008
    hardware release, Avaya began making MSPs part of the base
    package for all PBX purchasers, so that they no longer had to
    pay additional money for access to those maintenance
    features. They were, however, then subject to heightened
    contractual restrictions against using independent service
    providers (“ISPs”).7
    ISPs in fact became a fourth source of maintenance for
    Avaya PBX systems, and – from Avaya’s perspective at least
    – a very unwelcome one. Avaya has made no secret of its
    7
    The Avaya expert who testified about the change in
    policy suggested that the reason for the change was that the
    features available for purchase on the PBXs had become so
    numerous that Avaya began including many of them by
    default.
    12
    hostility to ISPs, and it acknowledges that it “has never given
    third parties the logins necessary to access the ODMCs
    needed to maintain PBXs.” (Opening Br. at 15.) As Avaya
    characterizes it, prior to 2003, there were no significant ISPs
    on the market, and they did not become noticeable market
    players until 2005. At that point, Avaya released an internal
    July 2005 bulletin affirming that “Avaya ... does not provide
    maintenance support for clients of or directly to unauthorized
    service providers” (J.A. 7043), and it recapitulated its policy
    that MSPs and self-maintenance licensing would not be
    available to customers who used ISPs. A 2006 federal court
    opinion rejected an antitrust suit challenging Avaya’s policy
    against giving ISPs maintenance software access.8
    In its campaign against ISPs, Avaya updated its
    customer agreements in 2008 to make explicit that PBX
    purchasers agreed not to use unauthorized third parties for
    8
    See United Asset Coverage, Inc. v. Avaya Inc., 409 F.
    Supp. 2d 1008, 1046 (N.D. Ill. 2006). That court’s analysis
    was critical of the kind of monopolization and tying claims
    now brought by TLI. Because “the software built into
    Avaya’s PBXs to facilitate their maintenance and repair is
    proprietary,” the court rejected the argument that maintenance
    and hardware were separate antitrust markets. 
    Id. at 1045-46.
    It also rejected the claim that Avaya had surprised its
    customers with a post-sale policy change, characterizing that
    monopolization claim as “border[ing] on the absurd” because
    “[n]o one has an unclouded crystal ball as to future events,
    nor does anyone have a vested right in the expectation that the
    future will remain the same as the present.” 
    Id. at 1046.
    13
    any service that required MSPs. Specifically, one license
    restriction stated that the
    Customer agrees not to ... allow any service
    provider or other third party, with the exception
    of Avaya’s ... resellers and their designated
    employees ... to use or execute any software
    commands that cause the software to perform
    functions that facilitate the maintenance or
    repair of any Product except ... those software
    commands that ... would operate if ... [MSPs]
    were not enabled or activated.
    (J.A. 7283.)
    2.    PDS Systems and Maintenance9
    The other Avaya equipment at issue in this case is the
    PDS system, the market for which is substantially smaller
    than the PBX market. Avaya presented evidence at trial that
    no more than 840 Avaya PDS systems were installed
    nationwide (about 20% of the total PDS market), with Avaya
    providing maintenance service to about 200 of those
    customers.10 PDS systems tend to induce less long-term
    9
    The phrase “PDS system” is redundant (because the
    “S” in PDS is “system”), but we use it for its colloquial ease,
    as the District Court did.
    10
    Because of the relatively small size of the PDS
    maintenance market, none of Avaya’s Business Partners has
    become a PDS maintenance provider.
    14
    intra-brand reliance than PBXs because the cost of an entirely
    new PDS is similar to the cost of upgrading an existing
    system.
    The PDS market is similar to the PBX market in at
    least one important respect. In both, Avaya says, the profits
    from maintenance contracts help fund the development of
    new systems and the upgrades of existing systems. Avaya
    regularly updates its PDS software with patches to “fix bugs
    or adapt the product to changing circumstances.” (Opening
    Br. at 14.) Prior to 2007, patches were available for free to
    PDS customers on Avaya’s website; after 2007, customers
    who purchased new PDS systems could only receive patches
    if they purchased a minimum of one year of software support
    from Avaya.
    3.    The Dispute between Avaya and TLI
    The two sides in this case present dramatically
    different stories of their dispute, which began in 2003.11
    Avaya’s story is that it simply enforced long-standing policies
    against a disloyal former contractor that was breaching
    contractual duties and dishonestly undermining Avaya’s
    relationships with its customers. TLI’s version is that Avaya
    retroactively sprung an anticompetitive policy on its
    customers that prevented them from using ISPs, in order to
    11
    Most issues before us are raised by Avaya, against
    whom the District Court entered judgment as a matter of law
    and against which a verdict was rendered. Nonetheless, both
    sides have appealed a variety of issues, and we endeavor to
    recount the facts neutrally.
    15
    vindictively force out of business a competitor who could
    provide better maintenance service at a lower cost.
    From 1996 to 2003, TLI was an Avaya Business
    Partner and sold Avaya systems. Around 2000, Avaya
    launched a program to encourage Business Partners to offer
    maintenance services. TLI took the opportunity.12 It claims
    it “invested millions in building its maintenance capabilities,”
    while continuing to loyally sell Avaya PBX systems –
    reaching roughly five million dollars in sales in 2002.
    (Answering Br. at 5.)
    The relationship between Avaya and TLI soured that
    same year, over TLI’s efforts to compete for maintenance
    contracts with other Business Partners and with Avaya
    directly. Avaya had introduced a revised set of obligations
    for its Business Partners, the new program being set forth in
    what Avaya called the “Avaya One” agreement. The intent
    was to limit intra-brand competition and instead promote
    inter-brand competition by encouraging Business Partners to
    expand the total Avaya market rather than compete with each
    other. As TLI characterizes it, the Avaya One agreement was
    a malicious surprise sprung on the Business Partners who had
    invested in their maintenance business at Avaya’s
    encouragement and were now restricted in their ability to
    compete for customers to get a return on that investment.
    12
    Avaya had laid off many of its service technicians
    and engineers, and it offered to subsidize their salaries if
    Business Partners would employ them and begin to offer
    maintenance services.
    16
    The formal relationship between Avaya and TLI ended
    in 2003. TLI had refused to sign on to any agreement that
    would limit its ability to compete for maintenance clients.
    Instead, it negotiated a separate agreement with an Avaya
    agent, under which TLI was exempted from most of the rules
    against competing for existing maintenance business. When
    higher-ups at Avaya learned of this non-conforming deal,
    they invoked a termination provision of the contract in July
    2003 that allowed them to end the deal on 60-days’ notice.13
    The two sides’ accounts again diverge as to what happened
    next.
    According to TLI, Avaya jumped the gun on the 60-
    day notice period and began prematurely terminating TLI’s
    access to its clients’ systems, while notifying remaining
    Business Partners that they should poach TLI’s clients. TLI
    says that Avaya then went on the warpath to sweep away
    ISPs, and that ODMC and MSP access restrictions were
    created to prevent ISPs from competing in the maintenance
    13
    Formally, there were two Avaya One agreements in
    place, one between Avaya and TLI and one between Avaya
    and TeamTLI.com. For the TLI agreement, Avaya invoked
    the termination clause on July 31, 2003, so that it terminated
    on September 30.         The TeamTLI.com agreement was
    finalized on July 24, Avaya served notice it was cancelling on
    September 24, and the termination was effective
    November 24. Because the agreement with TLI was the
    principal subject of Avaya’s breach of contract claims, and
    because the District Court analyzed the two contracts in
    tandem, for simplicity we do not address them separately
    because there is no substantive difference that we are aware
    of, and the difference in termination dates is irrelevant.
    17
    market. It claims that Avaya would keep customers in the
    dark about restrictions on ISP service until after the customers
    had already purchased an expensive system and were “locked
    in,” at which point Avaya would deliberately misconstrue the
    license contracts to assert that ISP maintenance was
    prohibited. TLI also accuses Avaya of other supposedly
    anticompetitive conduct, including shortening the PBX
    warranty period in an attempt to force customers to sign up
    for Avaya maintenance contracts and ending a program that
    allowed customers to gain MSP access without using an
    Avaya-authorized provider. TLI argues that it was the target
    of particularly hostile action by Avaya. First and foremost,
    TLI alleges that Avaya “sent threatening and misleading
    letters” to TLI’s “current and potential customers,
    discouraging them from doing business” with TLI based on a
    claim that “unauthorized access to the PDS/PBX system
    [was] a violation of federal and state laws,” a claim that TLI
    considers to be “without legal basis.” (Answering Br. at 9-10
    (internal quotation and editorial marks omitted).) Throughout
    this litigation, TLI has styled those letters as sowing “fear,
    uncertainty, and doubt” among its customers, and it has
    dubbed that correspondence the “FUD letters” for short.
    Additionally, TLI accuses Avaya of “trespassing on [TLI’s]
    customers’ systems and disabling their access to critical
    maintenance software” (Answering Br. at 10), as well as
    punitively instituting this lawsuit against TLI.
    In Avaya’s much different narrative, TLI engaged in
    underhanded tactics to peel off Avaya customers in ways that
    violated both tort law and the contractual obligations of TLI
    and its customers. According to Avaya, that unlawful
    conduct began when TLI, then still a Business Partner,
    improperly developed a disloyal commercial strategy based
    18
    on poaching Avaya customers. After TLI was terminated as a
    Business Partner, it continued to provide maintenance by
    using improperly acquired login credentials – either
    DADMIN logins gleaned from co-opted Business Partners or
    logins from customers who had MSP license agreements. To
    gain those logins, TLI convinced complicit Avaya Business
    Partners deceptively to submit login credential requests for
    certain TLI customers. TLI would then disconnect PBX
    systems from phone lines to prevent Avaya from changing the
    login passwords or from deactivating MSPs. Avaya also
    argues that TLI hired two former Avaya technicians to assist
    in tortious activity, one to “crack” Avaya login passwords and
    one to circumvent security systems in the software. All told,
    Avaya suggests that TLI made $20-34 million in profit from
    PBX maintenance using unlawfully-acquired access. This
    lawsuit was initiated as part of Avaya’s efforts to halt TLI’s
    allegedly illicit conduct.
    B.     Procedural Background
    Avaya filed suit on June 2, 2006, alleging a host of
    common law business torts, breach of contract, and violations
    of federal statutes, specifically the Digital Millennium
    Copyright Act and the Lanham Act. It sought both money
    damages and injunctive relief to halt TLI’s practices. Those
    claims were refined over the following four years, eventually
    resulting in the Fourth Amended Complaint (the
    “Complaint”), filed in February 2010, which presented the
    claims as they went to trial.14 TLI filed counterclaims,
    14
    By the time of that Complaint, Avaya’s claims
    against TLI were, in full, the following: misappropriation of
    trade secrets, tortious interference with contractual relations,
    19
    alleging numerous common law and federal antitrust
    violations and seeking both money damages and injunctive
    relief against what it considered Avaya’s anticompetitive
    conduct.15
    tortious interference with prospective economic advantage,
    fraud/ misrepresentation, violations of the Digital Millennium
    Copyright Act, false advertising and violations of the Lanham
    Act, trade libel and commercial disparagement, breach of
    contract, unfair competition, unjust enrichment, breach of the
    duty of loyalty, aiding and abetting former Avaya employees’
    misuse of proprietary information, and conspiracy
    15
    Specifically, TLI alleged the following antitrust
    violations: monopolization and attempted monopolization of
    the PBX maintenance market in violation of § 2 of the
    Sherman Act, tying PBX maintenance and software patches
    in violation of § 1 of the Sherman Act, tying PBX upgrades
    and maintenance in violation of § 1 of the Sherman Act,
    monopolization and attempted monopolization of the PDS
    maintenance market in violation of § 2 of the Sherman Act,
    tying PDS maintenance and software patches in violation of
    § 1 of the Sherman Act, tying PDS maintenance and upgrades
    in violation of § 1 of the Sherman Act, and conspiracy in
    violation of § 1 of the Sherman Act. TLI also asserted
    common law counterclaims: tortious interference with
    business/contractual relations, tortious interference with
    prospective business or economic advantage, injurious
    falsehood and trade libel/slander, and breach of the implied
    covenant of good faith and fair dealing.
    20
    Pretrial proceedings lasted for seven years, comprising
    extensive discovery and motions practice, during which many
    of the claims were resolved. In 2012, TLI’s common law
    claims were all dismissed by summary judgment. The
    District Court also dismissed TLI’s antitrust claims that
    alleged illegal tying between PBX system upgrades and
    maintenance. In addition, Avaya voluntarily dismissed its
    federal statutory claims and several of its common law claims
    before trial.16
    Some of the issues on appeal concern litigation
    conduct. TLI accuses Avaya of malicious litigation behavior,
    which allegedly cost TLI “millions of dollars in excess
    litigation costs and delayed resolution of the case for several
    years.” (Answering Br. at 13.) Specifically, TLI accuses
    Avaya of abusing the discovery process by making copious
    and unnecessary requests for documents and admissions and
    delivering an excessive number of documents to TLI late in
    the proceedings. TLI suggests that Avaya knowingly pursued
    meritless claims, namely those that it voluntarily dismissed on
    the eve of trial. And TLI further alleges that Avaya
    “routinely produced inadequately-prepared corporate
    designees for deposition” (id. at 15), served excessively long
    expert reports, and litigated complex Daubert motions to be
    able to present experts, only to drop the experts and
    “substantial portions” of the expert reports at trial (id.
    (quoting J.A. 352)). Avaya denies any allegations of bad
    16
    Those claims included misappropriation of trade
    secrets, tortious interference with contractual relations,
    violations of the Digital Millennium Copyright Act,
    violations of the Lanham Act, trade libel and commercial
    disparagement, and breach of the duty of loyalty.
    21
    faith conduct and defends its actions as nothing more than
    vigorous litigation in a complex case.
    The trial began on September 9, 2013, opening with
    Avaya’s remaining affirmative claims against TLI – for
    breach of contract, tortious interference with prospective
    economic gain, fraud, unfair competition, unjust enrichment,
    aiding and abetting former Avaya employees’ misuse of
    confidential information, and civil conspiracy. As the District
    Court described it, Avaya’s “jury presentation [] lasted two
    months, involved 35 witnesses, and spanned over 6,000 pages
    of transcript.” (J.A. 190.)
    TLI then moved for, and the District Court granted,
    judgment as a matter of law as to all of Avaya’s affirmative
    claims. The gist of the Court’s analysis was that TLI’s
    customers were authorized to use the maintenance commands
    and to give them to TLI, so that TLI could not have breached
    contractual or tort duties by gaining access to those
    commands.
    With Avaya’s affirmative case thrown out, TLI then
    proceeded to present its antitrust counterclaims to the jury,
    with that portion of the trial spanning nearly four months.
    When the presentation of evidence concluded, the Court held
    a fifteen-hour conference with the parties to reconcile their
    voluminous proposed jury instructions, eventually settling on
    a set of instructions that ran for 80 pages. Eight distinct
    antitrust claims ultimately went to the jury.
    On March 27, 2014, the jury returned a verdict, finding
    Avaya liable on two of the eight claims: (1) attempted
    monopolization of the PBX maintenance market, in violation
    22
    of § 2 of the Sherman Act, and (2) unlawfully tying PDS
    software patches to maintenance, in violation of § 1 of the
    Sherman Act. The jury awarded TLI $20 million in damages
    in a general verdict, which the Court trebled to $60 million in
    accordance with 15 U.S.C. § 15(a).
    After trial, both sides filed post-trial motions, seeking
    either judgment as a matter of law or a new trial on the claims
    now appealed to us, and the District Court denied those
    motions. TLI also requested an injunction ordering Avaya to
    allow its PBX customers to give ODMC access to ISPs. The
    Court granted that injunction, but it limited it to PBXs sold
    before May 2008 because Avaya had by then included in its
    sales contracts language to put customers on clear notice that
    they could not use ISPs for maintenance. Finally, the Court
    granted TLI’s motion for prejudgment interest under the
    Clayton Act, agreeing with TLI on several of its allegations
    that Avaya pursued non-meritorious claims in bad faith to
    prolong litigation. Ultimately, the District Court entered final
    judgment on September 16, 2014, awarding TLI
    $62,613,052.10.         Avaya timely appealed, and TLI
    conditionally cross-appealed.17
    17
    The District Court had jurisdiction under 28 U.S.C.
    §§ 1331, 1332, and 1367. We exercise jurisdiction pursuant
    to 28 U.S.C. § 1291.
    23
    III.   Avaya’s Appeals
    A.     Judgment as a Matter of Law on Avaya’s
    Common Law Claims
    We first take up Avaya’s appeal of the District Court’s
    grant of judgment as a matter of law on its common law
    claims against TLI for tortious interference with prospective
    business advantage, unfair competition, fraud, and breach of
    contract.18 Because all four claims are based on the same
    allegedly illicit conduct by TLI, we begin by providing a
    summary of the evidence of that conduct, as developed at
    trial. We then apply the state law relevant to each of the four
    causes of action. For each claim, we conclude that judgment
    as a matter of law was inappropriate.
    A motion for judgment as a matter of law under
    Federal Rule of Civil Procedure 50(a) “should be granted
    only if, viewing the evidence in the light most favorable to
    the nonmovant and giving it the advantage of every fair and
    reasonable inference, there is insufficient evidence from
    which a jury reasonably could find liability.” Lightning Lube,
    Inc. v. Witco Corp., 
    4 F.3d 1153
    , 1166 (3d Cir. 1993)
    (citation omitted).
    Credibility determinations, the weighing of the
    evidence, and the drawing of legitimate
    inferences from the facts are jury functions, not
    those of a judge. Thus, although the court
    18
    Avaya does not appeal the grant of judgment as a
    matter of law against its claims for civil conspiracy, aiding
    and abetting a breach of loyalty, and unjust enrichment.
    24
    should review the record as a whole, it must
    disregard all evidence favorable to the moving
    party that the jury is not required to believe.

    530 U.S. 133
    ,
    150-51 (2000) (internal quotation marks and citations
    omitted). Given that the District Court heard two months of
    testimony on Avaya’s common law claims, judgment as a
    matter of law could only have been appropriate in the
    extraordinary circumstance that none of that evidence could
    lead a reasonable jury to find that TLI was liable on any one
    of the common law claims.
    We exercise plenary review over the order granting the
    motion for judgment as a matter of law, and we apply the
    same standard as the District Court should have. Lightning

    . Though the District Court ably
    supervised the introduction of volumes of evidence and was
    attentive in managing this complex case, we cannot help but
    conclude that its decision to grant TLI’s motion for judgment
    as a matter of law was irretrievably flawed. Avaya provided
    ample proof of conduct that could support its common law
    claims, much of which was uncontroverted and came directly
    from the testimony of TLI executives themselves. While we
    have high regard for the fine jurist who was at the helm in the
    District Court, this case is a reminder that “judgment as a
    matter of law should be granted sparingly.” Goodman v. Pa.

    293 F.3d 655
    , 665 (3d Cir. 2002).
    25
    1.     Evidence Supporting Avaya’s
    Common Law Claims
    Avaya presented evidence that TLI engaged in conduct
    that was at best ethically dubious, and quite possibly
    unlawful. To summarize the conduct at issue, it is undisputed
    that TLI enlisted former Avaya employees to “hack” and
    “crack” Avaya systems, that it submitted deceptive requests
    for login access, and that it used Avaya’s proprietary
    knowledge – gained while still Avaya’s Business Partner – to
    compete directly against Avaya. As a result, TLI was able to
    lure a significant amount of business away from Avaya and
    its Business Partners. TLI’s surreptitious business dealings
    and its executives’ own admissions of secrecy belie any claim
    that it thought its own conduct was fair and proper.
    a.     Evidence of Unlawful Activity
    i.        Hacking and Cracking
    The first method TLI used to hack into its clients’
    Avaya systems was hiring former Avaya employee Dave
    Creswick to crack logins and passwords. Creswick knew that
    TLI needed the passwords “[t]o do their maintenance” in
    competition with Avaya. (J.A. 2277.) He would hack into
    systems and activate MSPs on TLI’s clients’ systems, and he
    also activated DADMIN login access several times.
    The evidence introduced at trial of the Creswick
    hacking scheme was copious, and came mostly from the
    testimony of TLI executives themselves. Chief Technology
    Officer Scott Graham acknowledged that TLI paid Creswick
    to “enable some logins and MSPs” (J.A. 2292) and that it
    26
    began paying Creswick for this service while TLI was still
    under contract as an Avaya Business Partner. CEO Douglas
    Graham acknowledged using Creswick as an “ex-Avaya
    employee [to] create a new password for the system[s].”
    (J.A. 2747.) Avaya introduced an email in which Douglas
    Graham offered Creswick “a flat rate of $300 a password for
    single situations and $200 a password if you do more [than]
    one password at a time.” (J.A. 6117.) In another email,
    Creswick bragged to Douglas Graham that “there has not
    been [an Avaya PBX] system created that I cannot get into.”
    (J.A. 6059.) TLI eventually developed additional means to
    access Avaya PBXs, and by 2008, it had begun to “read []
    passwords” for itself, using a method similar to (but simpler
    than) Creswick’s. (J.A. 2361.)
    TLI also hacked Avaya systems by hiring another
    former Avaya employee, Harold Hall, who used software
    “provided by Avaya” during his time as an Avaya employee
    to “beat” Avaya’s security systems. (J.A. 2293). Hall had
    taken the software, called an “ASG key,” with him when he
    left Avaya’s employment. He acknowledged at trial that he
    did not receive permission from Avaya to do so. Scott
    Graham admitted that Hall’s method was necessary to
    overcome “an additional security method that was
    implemented by Avaya on certain releases of the ... PBX
    software.” (J.A. 2365.) He conceded that he knew “Hall had
    [software] provided to him by Avaya” and that he “believe[d]
    [Hall] used it through most of his career at Avaya” before
    using that software “subsequently as a contractor.” (J.A.
    2366.) In his own testimony, Hall estimated that he had used
    the ASG key for TLI “40 [to] 60” times. (J.A. 3057.)
    27
    ii.        Deceptive Access
    Requests
    The second way that TLI gained access to Avaya’s
    PBX systems was to cajole Avaya Business Partners into
    submitting deceptive requests for login access. As Scott
    Graham characterized it, TLI would “work[] with several
    Business Partners” to have them “submit[] a DADMIN form
    at the customer’s request” – but, unbeknownst to Avaya, TLI
    would be the ultimate user.          (J.A. 2293.)   Graham
    acknowledged that, if Avaya had known that TLI was behind
    the request, it would not have enabled the DADMINs because
    Avaya was “doing everything [it] could to put [TLI] out of
    the maintenance business.” (J.A. 2338.) Therefore, as
    Graham put it, the submissions “did not identify [TLI] on
    there” and “did not have [TLI’s] name on there to identify to
    Avaya that [the customer] was also a customer of [TLI’s].”
    (J.A. 2338.) In response to an interrogatory, TLI identified
    seven Business Partners who cooperated in the scheme to
    send access requests “that resulted in the activation of
    DADMIN logins” that were used by TLI. (J.A. 3041.)
    iii.        Disloyal     Use       of
    Knowledge Gained As
    Avaya Business Partner
    TLI’s third method for surreptitiously gaining access
    to Avaya systems was to rely on proprietary information
    learned when it was under contract as an Avaya Business
    Partner. Scott Graham testified that “108 locations or about 8
    percent” of the PBX systems that TLI serviced “were systems
    for which TLI provided maintenance using a login that it had
    obtained from Avaya when TLI was a Business Partner.”
    28
    (J.A. 2423.)      An additional “17 percent” of TLI’s
    maintenance business was for “systems that were ... using a
    default login or password.” (J.A. 2424.) TLI “did indeed
    learn of [those default passwords] during the time that [TLI
    was] a Business Partner.” (J.A. 2332.)
    iv.        Subjective Knowledge of
    Wrongful Conduct
    Avaya also presented evidence that TLI knew that
    Avaya considered maintenance access to be proprietary and
    that TLI deliberately acted in secret to gain system access,
    from which a jury could infer malice or bad faith. Scott
    Graham admitted in his testimony that TLI “hid [its] activities
    from Avaya” and that the information about how TLI gained
    access was “carefully guarded” when dealing with customers
    – though he denied providing customers with affirmatively
    false information. (J.A. 2293-94.)
    TLI actually went to great lengths to conceal its
    activities from Avaya. Scott Graham acknowledged that if
    Avaya knew that TLI was behind the vicarious DADMIN
    login requests, it would not have provided them.
    Accordingly, TLI would have customers sign blank request
    forms and would not disclose to them the identity of the
    Business Partner that would actually submit the form, because
    “if the Business Partner was identified to the customer, that
    could get back to Avaya.” (J.A. 2345.) TLI believed (no
    doubt rightly) that if Avaya learned of that practice, it would
    have intervened to stop the unauthorized access.
    As for the hacking schemes, Douglas Graham
    acknowledged that “it was very important to [TLI] that Avaya
    29
    didn’t know about Mr. Creswick.” (J.A. 2748.) In an email,
    Graham wrote that one way TLI got “access to [Avaya]
    systems” was “having an ex-Avaya employee create a new
    password for the system,” and he suggested that “[i]f [Avaya]
    knew of” the manner in which TLI was getting access, it
    “would probably be raising it” in litigation. (J.A. 6363-64.)
    TLI executive Bruce Shelby testified that TLI would make
    customers sign non-disclosure agreements before revealing
    who its subcontractors were, for fear that Avaya would find
    out and “put pressure on all the Business Partners that were
    on our subcontractor list not to work with us.” (J.A. 2986.)
    He also testified that TLI did not want Avaya “to find out ...
    how TLI was gaining access to the on-demand maintenance
    commands.” (J.A. 2997-98.)
    Testimony also established that TLI acted to obfuscate
    its practices when dealing with its own customers. For
    example, when Avaya changed its customer contract
    language regarding DADMIN access, Scott Graham sent an
    email to TLI leadership suggesting a tactic to conceal the
    firm’s methods:
    In light of Avaya’s recent changes in
    contract language regarding [DADMIN]
    specifically, we want to eliminate that word
    from our vocabulary when talking to customers.
    When we refer to logins - we want to
    simply refer to them as “service logins[.”] ...
    Obviously, some customers will ask
    pointed enough questions, that we will need to
    30
    be more descriptive, but as a default we want to
    change our message.
    (J.A. 5817.) The obfuscation apparently worked; in fact, two
    of TLI’s customers testified that they did not know that TLI
    was not an authorized maintenance provider when they hired
    the firm.
    TLI also took preemptive actions to prevent Avaya
    from interrupting its activities. According to Scott Graham’s
    testimony, TLI knew that the MSPs were licensed by Avaya
    to each customer and that the licenses “all implied” that
    “Avaya could shut [the MSPs] off” at the end of a customer’s
    contractual relationship with Avaya. (J.A. 2382.) Therefore,
    as Douglas Graham put it in an email, TLI would “tak[e] over
    the system” of a customer it had successfully solicited,
    “before Avaya ha[d] time to turn the [MSPs] off, or change
    the passwords,” which was “simply done by disconnecting
    the phone line that links Avaya to the customer’s system.”
    (J.A. 6363.) Similarly, Harold Hall testified that he would
    access the Avaya systems using the DADMIN logins he had
    cracked with the software he had walked away with when he
    quit Avaya, and then he would change the DADMIN
    password. He testified that the practice was a “routine thing”
    that TLI did, and that it ensured that “nobody other than [TLI
    could] access that [system] using the DADMIN login.” (J.A.
    3055.) One TLI employee testified that she was instructed to
    tell customers who were cancelling a contract with Avaya to
    “change the line that they had in place” and to “change a
    password,” all “so that Avaya couldn’t access the system.”
    (J.A. 2463.)
    31
    b.     Harm to Avaya
    All of the common law claims at issue have as an
    element that Avaya establish actual damages resulting from
    TLI’s unlawful activity. At trial, Avaya presented evidence
    of several avenues through which TLI’s alleged
    misappropriation of maintenance access caused it financial
    harm.
    First, Avaya lost license revenue when TLI provided
    the misappropriated access to its customers, who would
    otherwise have had to license access from Avaya. Scott
    Graham testified that TLI provided customers with logins that
    went beyond the base customer logins. Douglas Graham
    testified to a specific instance in which TLI provided a high-
    level password to a client so that the client would “not have to
    pay Avaya for MSPs.” (J.A. 2720.) Shelby testified that TLI
    would “tell prospective customers that they did not need to
    pay for MSPs if they were to become a TLI maintenance
    customer,” “because [TLI] had another method to gain
    access.” (J.A. 3033.)
    Second, TLI would itself sell passwords to customers,
    as was established by Douglas Graham’s testimony. He
    described how TLI charged “setup fees” for customers who
    needed a new password. (J.A. 2750.) Also, “[t]here was a
    time where [TLI] would charge customers if [TLI] had to get
    a second password.” (J.A. 2750.) That TLI revenue gained
    by selling Avaya’s proprietary information could be a basis
    for disgorgement damages.
    Third, and most importantly, the allegedly
    misappropriated access enabled TLI to compete directly with
    32
    Avaya for maintenance customers, costing Avaya profit in its
    high-margin maintenance business. Scott Graham testified
    that, from 2001 on, TLI competed with Avaya for
    maintenance dollars. Douglas Graham acknowledged that,
    since that time, TLI “marketed ... its own maintenance, to
    existing Avaya maintenance customers,” and he identified
    one customer in particular that TLI “took over” from Avaya.
    (J.A. 2704-05.) Shelby acknowledged that TLI “targeted
    PBX owners with existing maintenance contracts because
    they were the ones ... who were most likely to spend money
    on PBX maintenance.” (J.A. 2983.) He also stated that, of
    those existing maintenance contracts, “[t]he vast majority
    were with Avaya.” (J.A. 2983.)
    Avaya presented evidence that TLI’s ability to
    compete for that business depended on the maintenance
    access that Avaya contends was misappropriated. Scott
    Graham agreed that “unless [TLI] could access the
    maintenance commands built into the software, [it] couldn’t
    ... do the maintenance.” (J.A. 2385.) He also stated that
    “[s]ome of the services” offered by TLI for the PBX
    maintenance at issue “do require the maintenance
    commands.” (J.A. 2294.) And he acknowledged that
    “generally” the commands at issue “can’t be executed by a
    customer level login with no MSPs,” hence requiring a
    higher-level login of the type that was gained by the various
    means just described. (J.A. 2294.)19
    19
    Avaya presented a specific example through the
    testimony of one maintenance client who was courted by TLI.
    That witness testified that his firm had traditionally used
    Avaya maintenance (either directly or through Business
    Partners), switched to TLI under the mistaken belief that it
    33
    The competition for business was especially costly to
    Avaya because maintenance was a major driver of the profits
    from its PBX and PDS systems.20 Avaya’s profit margin on
    the sale of PBX systems was substantially lower than its
    profit margin on the whole range of maintenance products.
    was a Business Partner, then terminated that arrangement
    upon discovering that TLI was not “able to provide [them]
    with the proper login credentials to support and administer the
    system” and thereafter “went back to Avaya for support.”
    (J.A. 2510.) Avaya therefore presented not only generalized
    evidence that TLI’s maintenance contracts were at Avaya’s
    expense, but a concrete example of how that substitution
    worked.
    20
    Indeed, Douglas Graham noted in an email that
    Avaya would frequently take losses in order to retain its
    extant maintenance contracts, another facet of TLI’s
    competitive strategy:
    TLI continues to have significant success in
    taking over existing Avaya maintenance
    contracts. Even when TLI loses, in most cases
    Avaya has to take a significant loss to win the
    deal. For example, TLI just lost International
    Paper.     At the time of TLI’s proposal,
    International Paper was paying Avaya over
    $4,000,000 a year. TLI’s proposal was for
    $2,800,000 a year. I have not gotten all the
    details, but I am confident that Avaya had to
    partner with a Business Partner and take a
    significant loss to keep TLI from winning this
    deal.
    (J.A. 6363.)
    34
    Even if Avaya did not retain the customer as a direct service
    client, the two other authorized routes for customers to obtain
    maintenance service – purchasing service from a Business
    Partner or purchasing licenses for self-maintenance – would
    also have benefited Avaya financially. As an Avaya
    executive testified, when a customer signs on with a Business
    Partner, it becomes a “customer ... that [Avaya] can look to
    sell additional products to.” (J.A. 2065) In some cases, the
    Business Partner would in turn sell Avaya maintenance
    service, providing direct revenue to Avaya. Even if the
    Business Partner sold its own branded maintenance, any such
    service was “going to ... include[] ... some Avaya content,”
    hence yielding business for Avaya. (J.A. 2569.) 21
    Moreover, if the jury credited Avaya’s case, it would
    have been able to apportion damages to different conduct,
    because it had evidence of TLI’s total maintenance earnings
    and the proportion of maintenance attributable to each form
    of allegedly unlawful access. Avaya’s accounting expert
    testified that, depending on which profit model was believed
    (the plaintiff’s or the defendant’s), TLI made between
    $20,260,092 and $31,160,190 from its maintenance of Avaya
    PBX systems between 2003 and 2010. TLI’s own analysis
    concluded that its maintenance services were based on logins
    procured in the following proportions: 8% was “obtained
    21
    Not incidentally, a maintenance relationship either
    directly with Avaya or with an authorized Business Partner
    also allowed Avaya to assert quality control over
    maintenance, which helped protect the value of Avaya’s
    brand reputation. When it came to independent providers,
    Avaya was “concerned about the quality of maintenance
    service that the customer receives.” (J.A. 2065.)
    35
    from Avaya when TLI was a Business Partner” (J.A. 2423);
    1% was using “a well-known Business Partner password”
    (id.); 5% was based on deceptive requests from other
    Business Partners; 24% was “obtained through Mr.
    Creswick” (J.A. 2424); 28% was “using a login that the
    customer had provided it access to” (id.); 17% was obtained
    through a “default login or password” (id.); and 16% was
    “obtained internally,” including “through use of the known
    key with Mr. Hall” and TLI’s internally-developed cracking
    method (id.). If the jury found each of those courses of
    conduct to be unlawful, the total would account for 99% of
    the profit that TLI garnered from its Avaya PBX maintenance
    business. Even limiting the analysis to just the more
    obviously problematic conduct – deceptive log-in requests,
    hacking and cracking, and using passwords TLI gained as a
    Business Partner – it accounts for 53% of TLI’s business.
    With all the foregoing considerations taken together,
    we conclude that Avaya presented substantial evidence that,
    but for TLI’s competition, made possible only by its alleged
    theft of proprietary information, Avaya would have received a
    significant portion of the money TLI’s clients spent on
    maintenance. Further, it would have been feasible for the
    jury to attribute particular losses to particular conduct.
    2.     Customer Contract Interpretation
    In granting judgment as a matter of law to TLI on
    Avaya’s common law claims, the District Court largely relied
    on its ruling that Avaya’s contracts with its equipment
    customers entitled those customers to give TLI access to their
    systems to perform maintenance. The District Court ruled
    that, as a matter of law, “Avaya failed to prove the software
    36
    licensing agreements entered into by TLI’s 470 customers
    upon purchasing their PBXs prohibited them from allowing
    TLI[] to access the ODMCs on their systems.” (J.A. 201.)
    Because that threshold legal determination was so central to
    the rest of the District Court’s analysis, we turn to considering
    whether it was correct.
    There is no dispute that New Jersey law governs this
    issue, according to the choice of law provision in the
    customer contracts, and under New Jersey law, “discerning
    contractual intent is a question of fact unless the provisions of
    a contract are wholly unambiguous.” Jaasma v. Shell Oil
    Co., 
    412 F.3d 501
    , 507 (3d Cir. 2005) (interpreting New
    Jersey law) (internal quotation marks and modifications
    omitted) (quoting In re Barclay Indus., Inc., 
    736 F.2d 75
    , 78
    n.3 (3d Cir. 1984)). “An ambiguity in a contract exists if the
    terms of the contract are susceptible to at least two reasonable
    alternative interpretations.” M.J. Paquet, Inc. v. N.J. Dep’t of
    Transp., 
    794 A.2d 141
    , 152 (N.J. 2002) (quoting Nester v.
    O’Donnell, 
    693 A.2d 1214
    , 1220 (N.J. Super. Ct. App. Div.
    1997)). When that is so, it is permissible to look to evidence
    outside the contract “as an aid to interpretation.” Chubb
    Custom Ins. Co. v. Prudential Ins. Co. of Am., 
    948 A.2d 1285
    ,
    1289 (N.J. 2008) (citation omitted).
    Two sets of license agreements are in dispute, those
    before and those after 2007. Each is the subject of a distinct
    question. For the pre-2007 agreements, the question is
    whether it was ambiguous that they permitted licensees – i.e.,
    Avaya customers – to provide access to ISPs. The post-2007
    agreements unambiguously barred giving such access, but it
    is disputed whether Avaya’s customers actually entered into
    those agreements. We conclude that, for both sets of
    37
    agreements, Avaya presented sufficient evidence to at least
    create disputes of material fact, so that those questions should
    have been answered by the jury, not the Court.
    In ruling that PBX license agreements unambiguously
    gave purchasers a right to use maintenance commands and to
    provide access to third parties, the District Court relied on
    language from the “Purchase/Service Agreement.” The
    Court’s conclusion was based on a provision in “[l]icensing
    agreements used from 1990 to 2003,” which “granted the
    purchaser ‘a personal, non-transferable and non-exclusive
    right to use ... all software and related documentation
    furnished under this agreement.’” (J.A. 204 (quoting license
    agreement, an example of which is at J.A. 5856).) In the
    District Court’s reading, that language gave Avaya PBX
    customers a “personal ... right” to use MSPs, which the Court
    viewed as “software ... furnished under this agreement.” In
    the Court’s view, that right to use MSPs extended to the
    customer’s maintenance provider, whether an employee or an
    independent contractor such as TLI.22
    22
    In 2003, Avaya updated the agreements. It left the
    quoted language in place but added a new clause stating that
    the “[c]ustomer will make the Software available only to
    employees, contractors, or consultants with a need to know,
    who are obligated to comply with all license restrictions
    contained in the Agreement and to maintain the secrecy of the
    Software.” (E.g., J.A. 5241.) The District Court interpreted
    the language about “contractors[] or consultants” to be
    “consistent with the ... construction of licensing agreements
    that allow third-party use for the licensee’s benefit.” (J.A.
    205 n.26.) It therefore considered that contract term to be
    evidence that PBX owners were permitted to use independent
    38
    Avaya challenges the District Court’s interpretation of
    those agreements, arguing that the MSPs required to perform
    maintenance were not in fact “furnished under” the
    Purchase/Service Agreement, so that customers did not have a
    “right to use” them. (Opening Br. at 30.) Instead, MSPs
    were “licensed separately through an MSP Addendum ... or
    Maintenance Assist agreement.” (Id.) “Avaya delivered new
    equipment with MSPs turned off, enabled them only if
    customers signed a separate ... agreement, and disabled them
    if that agreement expired.” (Id.) Although customers could
    maintain their PBX systems without MSPs, it was “just not as
    efficient” to do so without the remote access that MSPs
    allowed (J.A. 1995) – hence the value of executing an
    agreement to activate MSPs.
    We do not need to answer who has the better reading
    of the contracts because, at a minimum, they are ambiguous,
    and the District Court erred in ruling that Avaya’s reading is
    untenable. MSPs may have been embedded in the software
    given to customers, but customers’ ability to access them
    required a separate purchase from Avaya. If the District
    Court’s interpretation were correct, then any time a customer
    downloaded a piece of software that had components
    requiring additional payment and permissions, courts would
    treat the entire software and all its components as having been
    “furnished” to the customer in the original purchase. That is
    questionable, and the contrary interpretation is, at the very
    least, plausible. Moreover, given that Avaya’s business
    model was dependent on selling base equipment and then
    licensing and enabling additional features such as MSPs, the
    contractors for maintenance and to provide them with system
    access.
    39
    conclusion that those features were unambiguously meant to
    be “furnished” in the base purchase is far from clear. As
    Avaya points out, “[h]undreds of self-maintenance customers
    paid Avaya for ... access commands,” which would “make no
    sense if the Purchase/Service Agreements already entitled
    customers” to them. (Opening Br. at 32.) Avaya, its
    customers, and even TLI did not read the agreements that way
    before the lawsuit, and the District Court erred in declaring
    that the terms were unambiguously contrary to all the parties’
    understandings.
    Avaya also notes that in 1999, the agreements were
    modified to include a provision that a customer “will not
    enable or attempt to permit any third party to enable software
    features or capacity (e.g. additional storage hours, ports, or
    mailboxes) which Avaya licenses as separate products
    without Avaya’s prior written consent.” (J.A. 205 n.24.)
    Based on that language, Avaya argues that customers were
    barred from allowing an ISP to enable features, such as
    MSPs, without Avaya’s consent.           The District Court,
    however, did not consider that provision to apply to MSPs. It
    read the list of enumerated examples – “storage hours, ports
    ..., and voice mailboxes” – to be “clearly incongruous” with
    MSPs. (Id.) Accordingly, the Court ruled that MSPs were
    unambiguously not a “feature[] or capacity” subject to the
    provision’s restrictions.
    For much the same reasons that we disagree with the
    District Court’s construction of the “furnished under”
    language, we also conclude that it was improper to determine
    that terms “features or capacit[ies]” were unambiguous and
    did not apply to MSPs. Storage hours, additional ports, and
    mailboxes are some examples of the add-ons that Avaya
    40
    licensed separately, but MSPs and ODMCs that provided
    remote maintenance access might rationally be viewed by a
    jury as being just as much “features” that enhance a
    customer’s use of a PBX system.23 Not only did customers’
    behavior provide some corroboration of Avaya’s
    interpretation of the contract, TLI’s did as well. If the
    agreements unambiguously permitted customers to give TLI
    access to MSPs, there would have been little reason for its
    secretive efforts to gain maintenance access. Indeed, Scott
    Graham was asked at trial whether he “knew that MSPs were
    not part of the original sale of the PBX to the customers,” and
    he responded: “Yes, and that was one of the big problems.”
    (J.A. 2303.) In light of the imprecision of the words
    “features” and “capacity” and the extrinsic evidence
    23
    TLI argues that, in Avaya’s “detailed ‘feature’
    manuals,” Avaya “did not once identify MSPs as a ‘feature.’”
    (Answering Br. at 84 (citing J.A. 2407).) We agree that
    testimony about those features manuals, and the absence of
    any mention of MSPs in them, would be relevant for the jury
    to consider in interpreting the meaning of the 1999
    modifications. But, as an Avaya system engineer put it at
    trial, the PBX software is “able to do a vast number of
    things,” and customers could pick and choose which “aspects
    of the software” to purchase. (J.A. 1886.) That Avaya chose
    to highlight more glamorous capacities in its features manuals
    – instead of intermediate commands and functions that
    allowed remote-access maintenance – does not foreclose a
    jury determination that such access was indeed a feature of
    the product. Given that so few customers performed their
    own maintenance, that lack of emphasis may make perfect
    sense to a jury.
    41
    supporting Avaya’s interpretation of the contract, we
    conclude that the District Court erred in ruling as a matter of
    law that the 1999 additions to Avaya’s PBX contracts
    unambiguously did not apply to MSPs.
    Having resolved that the District Court erred in
    construing the pre-2007 customer contracts to be
    unambiguously contrary to Avaya’s interpretation, we turn to
    the post-2007 agreements.24          The District Court
    acknowledged that the 2007 version of the licensing
    agreement clearly “obligated the purchaser to refrain from
    using a third-party maintenance provider,”25 but it ruled that
    “Avaya did not introduce any evidence indicating that [TLI’s]
    24
    The District Court made note of the fact that only
    “eight out of [TLI’s] 470 customers purchased their PBXs in
    2007 or after,” and that the 2007 contract modification “came
    into existence well after Avaya initiated the instant suit in
    June of 2006.” (J.A. 206-07 n.27.) Although allegedly
    unlawful access to post-2007 systems may not have been a
    large contributor of TLI’s business or the motivation for
    Avaya’s suit, that goes to the question of damages, not
    liability.
    25
    The agreement provided that the “[c]ustomer agrees
    not to ... allow any service provider or third party, with the
    exception of Avaya’s authorized channel resellers and their
    designated employees ... to use or execute any software
    commands that cause the software to perform functions that
    facilitate the maintenance or repair of any Product except that
    a service provider ... may execute those software commands
    that ... would operate if ... [MSPs] were not enabled or
    activated.” (J.A. 7283.)
    42
    customers signed such a licensing agreement, and
    consequently this iteration of the agreement cannot be used to
    prove that [TLI’s] customers were prohibited from granting
    TLI[] access to the ODMCs on their PBXs.” (J.A. 206.)
    Again, the Court was wrong.
    Avaya did present sufficient evidence to establish a
    dispute of material fact, which should have gone to the jury.
    The form agreement itself was in evidence, and an Avaya
    employee testified that the standard form agreements as of
    2008 included the specific reference restricting use of MSPs.
    That employee also explained that the forms were crafted by
    a “forms committee” that ensured that uniform terms and
    conditions were “incorporated into the templates,” which
    were then incorporated into “procedures under which [Avaya]
    used form agreement[s]” for PBX equipment, software, and
    maintenance sales. (J.A. 2615.) Given the evidence of
    Avaya’s centralized form-drafting procedure, an example of
    an actual prototypical form, and examples of earlier
    generations of forms that were in fact signed by customers, a
    jury could have reasonably found that the post-2007 form
    agreements were in fact reflective of PBX purchasers’ license
    obligations. It was thus improper for the District Court to
    resolve the question as a matter of law rather than leave it to
    the jury.
    43
    3.     Tortious Interference with Prospective
    Business Advantage
    We now turn to the specific claims that Avaya asks us
    to revive. We first consider count three of its Complaint, in
    which Avaya set forth a claim for tortious interference with
    prospective economic advantage.
    As a federal court sitting in diversity, and as is
    undisputed by the parties, we are obligated to apply New
    Jersey’s law to the tort claims. See Lorenzo v. Pub. Serv.
    Coordinated Transp., 
    283 F.2d 947
    , 948 (3d Cir. 1960) (per
    curiam). In Printing Mart-Morristown v. Sharp Electronics
    Corp., the Supreme Court of New Jersey held that, in a claim
    of tortious interference with prospective business advantage,
    “[w]hat is actionable is ‘[t]he luring away, by devious,
    improper and unrighteous means, of the customer of
    another.’” 
    563 A.2d 31
    , 36 (N.J. 1989) (quoting Louis
    Kamm, Inc. v. Flink, 
    175 A. 62
    , 66 (N.J. 1934)). To prevail
    on such a claim, Avaya “was required to show [1] that it had
    a reasonable expectation of economic advantage, [2] which
    was lost as a direct result of [TLI’C’s] malicious interference,
    and [3] that it suffered losses thereby.” Ideal Dairy Farms,
    Inc. v. Farmland Dairy Farms, Inc., 
    659 A.2d 904
    , 932 (N.J.
    Super. Ct. App. Div. 1995) (citation omitted).26
    26
    We earlier parsed New Jersey law to further
    subdivide the tort, essentially by breaking out the second part
    of the Ideal Dairy Farms formulation into three elements. As
    we put it then, the tort comprised five elements:
    1) a plaintiff’s reasonable expectation of
    economic benefit or advantage, (2) the
    defendant’s knowledge of that expectancy, (3)
    44
    In terms of the first element – protectable economic
    expectations – the Supreme Court of New Jersey has held that
    “[i]t is not necessary that the prospective relation be expected
    to be reduced to a formal, binding contract,” and that such
    prospective relations include “the opportunity of selling or
    buying land or chattels or services, and any other relations
    leading to potentially profitable contracts.” Printing 
    Mart, 563 A.2d at 39
    (quoting Restatement (Second) of Torts
    § 766B cmt. c (1979)). Courts have found “a reasonable
    expectation of economic gain in as slight an interest as
    prospective public sales.” 
    Id. at 38
    (collecting cases).
    Protectable economic expectations can arise from both
    existing and potential customers. “Tortious interference
    developed under common law to protect parties to an existing
    or prospective contractual relationship from outside
    interference.” 
    Id. at 38
    (emphasis added) (citation omitted).
    Satisfaction of the first element does not turn on whether the
    customer is characterized as current or prospective, but rather
    whether the facts of the case “giv[e] rise to some ‘reasonable
    the     defendant’s    wrongful,   intentional
    interference with that expectancy, (4) in the
    absence of interference, the reasonable
    probability that the plaintiff would have
    received the anticipated economic benefit, and
    (5) damages resulting from the defendant’s
    interference.
    Fineman v. Armstrong World Indus., Inc., 
    980 F.2d 171
    , 186
    (3d Cir. 1992) (citing Printing 
    Mart, 563 A.2d at 37
    ;
    Restatement (Second) of Torts § 766B)).
    45
    expectation of economic advantage.’” 
    Id. at 37
    (quoting
    Harris v. Perl, 
    197 A.2d 359
    , 363 (N.J. 1964)).27
    The second element – malicious interference – requires
    only “the intentional doing of a wrongful act without
    justification or excuse.” 
    Id. at 39
    (quoting Louis Schlesinger
    Co. v. Rice, 
    72 A.2d 197
    , 203 (N.J. 1950)). Wrongful
    conduct, always viewed in the specific context of the case
    presented, is generally defined by reference to custom in the
    industry. It is conduct that “would not be sanctioned by ‘the
    rules of the game.’” 
    Id. at 40.
    “[T]he line must be drawn
    where one competitor interferes with another’s economic
    advantage through conduct which is fraudulent, dishonest, or
    illegal.” Ideal Dairy 
    Farms, 659 A.2d at 936
    (citation
    omitted). A benign, or pro-competitive, motive does not
    absolve misconduct. “While competition may constitute
    justification, a defendant-competitor claiming a business-
    27
    Printing Mart illustrates how broad a protectable
    prospective economic advantage may be. The corporate
    plaintiff had performed printing services for Sharp
    Electronics for several years. When Printing Mart submitted
    a bid on the latest Sharp project, there was evidence that
    Sharp employees rigged the bidding process to enable a
    Printing Mart competitor to win the contract. Printing Mart
    sued Sharp, three of its employees, and three competitors for
    intentional interference with prospective economic relations.
    The trial court dismissed the complaint on the basis that no
    contract obligated Sharp to do business with Printing Mart.
    The Supreme Court of New Jersey reversed, holding that,
    although a complaint based on tortious interference must
    allege facts that show a protectable right, the right “need not
    equate with that found in an enforceable contract.” Printing
    
    Mart, 563 A.2d at 37
    .
    46
    related excuse must justify not only its motive and purpose
    but also the means used.” 
    Id. at 933
    (citation omitted).
    In Lamorte Burns & Co. v. Walters, the Supreme
    Court of New Jersey held that the “taking of plaintiff’s
    confidential and proprietary property and then using it
    effectively to target plaintiff[’s] clients, is contrary to the
    notion of free competition that is fair.” 
    770 A.2d 1158
    , 1172
    (N.J. 2001). In that case, two of Lamorte’s employees
    collected information on its clients with the purpose of using
    it to start their own business in direct competition with
    Lamorte. 
    Id. at 1162.
    The court held that such conduct was
    sufficient to make out a claim of tortious interference, so that
    the targeting of a company’s current clients was sufficient to
    ground a tortious interference claim. 
    Id. at 1172.
            For a plaintiff to establish the third element, loss and
    causation, there must be “proof that if there had been no
    interference there was a reasonable probability that the victim
    of the interference would have received the anticipated
    economic benefits.” Printing 
    Mart, 563 A.2d at 41
    (quoting
    Leslie Blau Co. v. Alfieri, 
    384 A.2d 859
    , 865 (N.J. Super. Ct.
    App. Div. 1978)). As the Appellate Division of the New
    Jersey Superior Court has explained, “[i]t is sufficient that
    plaintiff prove facts which, in themselves or by the inferences
    which may be legitimately drawn therefrom, would support a
    finding that, except for the tortious interference by the
    defendant with the plaintiff’s business relationship with
    [another party], plaintiff would have consummated the sale
    and made a profit.” McCue v. Deppert, 
    91 A.2d 503
    , 505-06
    (N.J. Super. Ct. App. Div. 1952).
    The District Court here decided that TLI’s access was
    not itself wrongful and that, therefore, Avaya’s tortious
    47
    interference claim must fail. That conclusion rested on two
    propositions: first, that Avaya had previously allowed TLI to
    provide maintenance, and, second, that “customers’ licensing
    agreements specifically allow[ed] for third-party service
    providers.”    (J.A. 226.)      Both those propositions are
    problematic in ways that undermine the District Court’s
    decision.
    As to the first point, the District Court was wrong to
    conclude that TLI was entitled to access ODMCs merely
    because it had been allowed to do so while it was an Avaya
    Business Partner. Of course TLI was permitted access when
    it was a contractual partner of Avaya’s, but the District Court
    provided no rationale to explain why that access survived the
    termination of that relationship. By close analogy, former
    employees in Lamorte were entitled to use their employer’s
    proprietary customer information while they were working
    for that employer, but they were not entitled to use that
    information when they left to become 
    competitors. 770 A.2d at 1172
    . Likewise, TLI was entitled to access ODMCs when
    it was an authorized Avaya Business Partner, but there is no
    reason it could expect that its access to proprietary software
    and logins would survive when it struck out on its own to
    compete directly against Avaya.
    As to the second point, we have already explained in
    detail why the District Court erred in concluding that Avaya
    customers were unambiguously entitled to give TLI remote
    access to perform maintenance. Even if the District Court
    were correct, however, that would not immunize TLI from a
    tortious interference claim when it comes to stealing away
    customers who had service contracts with Avaya. In Wear-
    Ever Aluminum, Inc. v. Townecraft Industries, Inc., the
    48
    Chancery Division of the New Jersey Superior Court
    emphasized that, even though the plaintiff company’s
    contracts with its employees were terminable at will, that did
    not permit a third party to interfere with the employment
    relationship. 
    182 A.2d 387
    , 393 (N.J. Super. Ct. Ch. Div.
    1962). Even if the contract in question permits an act
    eventually taken by a customer, “a stranger to the contract
    may not exercise his will in substitution for the will of either
    of the parties to the contract.” 
    Id. Moreover, even
    if TLI
    could have lawfully obtained access to MSPs and ODMCs
    from Avaya’s customers, that did not insulate it from tort
    liability for the methods it actually used to access the
    maintenance commands. If a homeowner gives a neighbor
    permission to borrow tools, the neighbor is not thereby
    insulated from a trespass suit if he chooses to break into the
    garage to get them.
    Having rejected the District Court’s assessment of
    those two threshold matters, we turn next to its application of
    a multifactor test for tortious interference from the
    Restatement (Second) of Torts § 767 (1979).28 Assuming for
    the moment that the Court was applying the right test – and
    28
    The District Court cited Printing 
    Mart, 563 A.2d at 752
    , for the proposition that New Jersey courts have adopted
    the multi-factor test from the Restatement. In fact, Printing
    Mart adopted § 766B, but subsequent case law from the
    Supreme Court of New Jersey suggests that § 767 is also
    persuasive. See Nostrame v. Santiago, 
    61 A.3d 893
    , 901 (N.J.
    2013) (“In determining whether the conduct complained of is
    improper, the Restatement offers general guidance,
    identifying a variety of relevant considerations.” (citing
    Restatement (Second) of Torts § 767)).
    49
    we think looking to the case law may have been more
    productive – the District Court nonetheless misstepped in its
    legal ruling. Section 767 lists the following factors for
    consideration:
    (a) the nature of the actor’s conduct,
    (b) the actor’s motive,
    (c) the interests of the other with which the
    actor’s conduct interferes,
    (d) the interests sought to be advanced by the
    actor,
    (e) the social interests in protecting the freedom
    of action of the actor and the contractual
    interests of the other,
    (f) the proximity or remoteness of the actor’s
    conduct to the interference and
    (g) the relations between the parties.
    The factors in that test are laden with subjective value
    judgments that will rarely be answerable as a matter of law.
    Nonetheless, and in the face of the already-recounted
    unflattering evidence against TLI, the District Court
    concluded that “[e]very single factor strongly indicates that
    [TLI’s] conduct d[id] not rise to the level ... the law
    proscribes.” (J.A. 227.) We disagree.
    First, the District Court stated that TLI acted with
    proper competitive motive and interest.29 But, even assuming
    29
    Although the District Court was not explicit in
    enumerating which factors of the Restatement’s seven-factor
    test it was considering, we infer from its argument that it here
    considered factors (a), (b), and (d) together – respectively, the
    50
    that were true, a pro-competitive motive or interest does not
    absolve misconduct that falls afoul of the first factor’s
    consideration of the nature of the conduct. Again, “[w]hile
    competition may constitute justification, a defendant-
    competitor claiming a business-related excuse must justify
    not only its motive and purpose but also the means used.”
    Ideal Dairy 
    Farms, 659 A.2d at 933
    .
    Second, the Court considered the nature of the
    protected interest, and it observed – without further comment
    or citation to authority – that “the law does not protect as
    forcefully a firm’s economic interest in possible, future
    customers as it does interests in contracting parties.” (J.A.
    228.) Whether or not that is true, TLI was in fact interfering
    with Avaya’s relationships with then-existing maintenance
    customers.        There was nothing speculative, or
    underwhelming, about that economic interest.
    Third, in considering society’s interest, the District
    Court found that TLI’s conduct “brought greater competition
    to the market and challenged widespread and vexatious
    threats of litigation.” (J.A. 228.) We do not believe the
    District Court was in a position to weigh the relative social
    merits of TLI’s conduct with Avaya’s proprietary interests in
    its software and its legitimate business expectations with its
    maintenance customers. That is exactly the kind of factual
    and ethical determination meant for the jury rather than the
    Court.
    nature of TLI’s conduct, its motive, and the interests it sought
    to advance.
    51
    Fourth, in considering the proximity of TLI’s conduct
    to the interference, the District Court emphasized that TLI’s
    “interference was far removed from their allegedly improper
    conduct” because it only accessed the ODMCs after the
    customer in question had left Avaya. (J.A. 229.) But the
    customers never would have left Avaya if TLI had not been
    able to promise ODMC access. The allegedly tortious
    conduct that enabled that access was therefore the sine qua
    non of TLI’s business.
    Finally, in considering the relations of the parties, the
    District Court determined that that factor “counsels for a
    finding of lawful conduct, as a mere four months after it
    signed the modified Avaya One agreement, and not long after
    originally encouraging TLI to invest in its maintenance
    business, Avaya cancelled the contract, thereby jeopardizing
    [TLI’s] monetary investment and business model.” (J.A. 229-
    30.) That TLI chose to compete against Avaya rather than
    accept the standard Business Partner arrangement – and
    therefore prompted Avaya to terminate their relationship –
    cannot insulate TLI’s allegedly tortious conduct. Avaya’s
    supposed bad acts and predatory conduct may end up
    supporting TLI’s antitrust counterclaims, but the District
    Court provided no authority to suggest that those acts
    permitted TLI to engage in hacking or fraud in retaliation for
    its termination as a Business Partner.
    A straightforward application of New Jersey’s test for
    tortious interference with prospective economic advantage
    leads, we believe, to the conclusion that Avaya presented
    sufficient evidence from which a reasonable jury could
    conclude that TLI tortiously interfered with Avaya’s
    prospective business advantage. Avaya had a reasonable
    52
    expectation of ongoing business with its own customers, who
    are the targets of TLI’s sales efforts. As to the “malicious
    interference” element, we hold that a jury could reasonably
    have concluded that TLI’s methods – including, as examples,
    its hacking, dishonest login requests, and use of proprietary
    information learned while an Avaya Business Partner – were
    fraudulent, dishonest, or otherwise contrary to the ethical
    standards of the industry. TLI presented no evidence that its
    actions were consistent with industry norms, and we would be
    loath to hold that there was no jury question here, even if it
    had. That leaves only the loss and causation element. The
    evidence could support a conclusion that TLI’s interference
    resulted in Avaya losing direct maintenance contracts with
    customers. Moreover, even if customers independently
    terminated their direct service contracts with Avaya, if they
    had turned to other authorized maintenance methods instead
    of using TLI – whether using a Business Partner or self-
    maintaining – Avaya would still have profited because, as
    earlier noted, those methods also produced revenue for
    Avaya. Avaya thus presented sufficient evidence from which
    a jury could conclude that Avaya suffered damages, given
    that any money earned by TLI must have come from Avaya’s
    pockets to at least some extent.
    In sum, the District Court improperly made inferences
    in favor of the moving party, TLI, as to both contract
    interpretation and tortious interference with prospective
    economic advantage, and it failed to recognize the sufficiency
    of the evidence Avaya had adduced. If the jury had been
    allowed to draw its own inferences from the evidence, it may
    have agreed with the District Court that TLI’s conduct was
    somehow permitted by Avaya’s customer contracts. But the
    jury may very well have determined that TLI’s actions were
    53
    not shielded by the customer contracts and were instead
    unethical, against the public interest, and ultimately tortious.
    We express no opinion on the correct answer in this dispute,
    holding only that the matter was for the jury to decide.
    4.     Unfair Competition
    Next, we consider Avaya’s unfair competition claim.
    New Jersey law is not precise about what constitutes unfair
    competition. But while “[t]he amorphous nature of unfair
    competition makes for an unevenly developed and difficult
    area of jurisprudence,” at heart it “seeks to espouse some
    baseline level of business fairness.” Coast Cities Truck Sales,
    Inc. v. Navistar Int’l Transp. Co., 
    912 F. Supp. 747
    , 786
    (D.N.J. 1995) (interpreting New Jersey law) (citations
    omitted).30 New Jersey courts have deliberately kept the
    standard of liability somewhat adaptable, so that it may fit
    changing circumstances: “the purpose of the law regarding
    unfair competition is to promote higher ethical standards in
    the business world. Accordingly, the concept is deemed as
    flexible and elastic as the evolving standards of commercial
    morality demand.” Ryan v. Carmona Bolen Home for
    Funerals, 
    775 A.2d 92
    , 95 (N.J. Super. Ct. App. Div. 2001)
    (internal quotation marks and citations omitted) (quoting N.J.
    30
    Other business torts – including tortious interference
    – can themselves support an unfair competition claim. Coast
    
    Cities, 912 F. Supp. at 786
    . Our conclusion that the tortious
    interference claim should have proceeded to the jury is itself
    sufficient to overturn the judgment as a matter of law on the
    unfair competition claim. Our analysis here focuses on those
    aspects of unfair competition that are distinct from tortious
    interference.
    54
    Optometric Ass’n v. Hillman-Kohan, 
    365 A.2d 956
    (N.J.
    Super. Ct. Ch. Div. 1976)).
    In New Jersey, unfair competition is commonly
    invoked for claims similar to misappropriation of trade
    secrets or commercial identity. An unfair competition claim,
    however, protects more information than a traditional trade
    secret claim. See Torsiello v. Strobeck, 
    955 F. Supp. 2d 300
    ,
    314 (D.N.J. 2013) (“Under New Jersey law, to be judicially
    protected, misappropriated information need not rise to the
    level of the usual trade secret, and indeed, may otherwise be
    publicly available.” (quoting Platinum Mgmt., Inc. v. Dahms,
    
    666 A.2d 1028
    , 1038 (N.J. Sup. Ct. Law Div. 1995))). For
    example, in the Lamorte case, the Supreme Court of New
    Jersey reinstated summary judgment against the plaintiff’s ex-
    employees who took their former employer’s “client names,
    addresses, phone and fax numbers, file numbers, claim
    incident dates, claim contact information, and names of the
    injured 
    persons.” 770 A.2d at 1162
    . The court endorsed the
    statement “that an agent must not take ‘unfair advantage of
    his position in the use of information or things acquired by
    him because of his position as agent or because of the
    opportunities which his position affords.’” 
    Id. at 1167
    (quoting Restatement (Second) of Agency § 387 cmt. b
    (1958)). The court emphasized that “the [client-specific]
    information was available to defendants for their use in
    servicing clients on behalf of Lamorte only,” and that
    “defendants also knew that Lamorte had an interest in
    protecting that information.” 
    Id. at 1167
    . Collectively, those
    facts established that the “information taken by defendants
    was confidential and proprietary information belonging to
    plaintiff.” 
    Id. at 1168.
    55
    What constitutes misappropriation is somewhat vague.
    “It is not possible to formulate a comprehensive list of the
    conduct that constitutes ‘improper’ means of acquiring a trade
    secret.” Restatement (Third) of Unfair Competition § 43 cmt
    c. (1995). Generally, however, “‘[i]mproper’ means ...
    include theft, fraud, unauthorized interception of
    communications, inducement of or knowing participation in a
    breach of confidence, and other means either wrongful in
    themselves or wrongful under the circumstances of the case.”
    
    Id. § 43.
    Even a legitimate business purpose will not excuse
    otherwise tortious conduct if the means used are improper.
    See 
    Lamorte, 770 A.2d at 1171
    . As another court has put it,
    [t]he key to determining the misuse of the
    information is the relationship of the parties at
    the time of disclosure, and its intended use.
    This tort tends to arise where an ex-employee
    uses confidential information to assist a
    competitor. A court may look to whether the
    information is public, whether it was provided
    in the course of employment for the sole
    purpose of servicing clients, how detailed the
    information is, and whether the party using the
    information is aware of the information holder’s
    interest in protecting the information ... .
    
    Torsiello, 955 F. Supp. 2d at 314
    (internal quotation marks
    and citations omitted).
    For a plaintiff to establish damages, New Jersey law
    allows recovery under a disgorgement theory in cases of
    unfair competition. See Castrol, Inc. v. Pennzoil Quaker
    State Co., 
    169 F. Supp. 2d 332
    , 345-46 (D.N.J. 2001) (ruling
    56
    that the plaintiff in that case was “entitled to disgorgement of
    [the defendant’s] profits” for its “claims under the New Jersey
    Common Law of Unfair Competition ... .”).31 Therefore, in
    place of proving specific damages, Avaya could properly seek
    disgorgement of TLI’s profits from any conduct the jury
    found tortious.
    We hold that Avaya presented sufficient evidence that
    a reasonable jury could have concluded that there was unfair
    competition under a misappropriation theory. The District
    Court’s grant of judgment as a matter of law was thus
    erroneous. TLI gained access to proprietary information –
    namely ODMC login passwords – using hacking, the
    solicitation of disloyal former Avaya employees, and
    information learned during TLI’s own time as an Avaya
    Business Partner. A jury could have determined that TLI’s
    methods of gaining Avaya’s proprietary information
    constituted misappropriation. Likewise, Avaya could show
    damages under either a lost profit theory or a disgorgement
    theory. Given that such a large proportion of TLI’s well-
    accounted profits resulted from conduct that Avaya alleges
    was rooted in the misappropriation or proprietary
    information, the disgorgement theory may have been simple
    for the jury to apply to determine damages.
    5.     Fraud
    31
    See also Restatement (Third) of Unfair Competition
    § 45 (1995) (“One who is liable to another for an
    appropriation of the other’s trade secret ... is liable for the
    pecuniary loss to the other caused by the appropriation or for
    the actor’s own pecuniary gain resulting from the
    appropriation, whichever is greater ... .”).
    57
    We next consider Avaya’s common law fraud claim.
    Under New Jersey law,
    proof of common law fraud requires the
    satisfaction of five elements: [1] a material
    misrepresentation by the defendant of a
    presently existing fact or past fact; [2]
    knowledge or belief by the defendant of its
    falsity; [3] an intent that the plaintiff rely on the
    statement; [4] reasonable reliance by the
    plaintiff; [5] and resulting damages to the
    plaintiff.
    Liberty Mut. Ins. Co. v. Land, 
    892 A.2d 1240
    , 1247 (N.J.
    2006). A jury must find fraud by clear and convincing
    evidence, a standard which demands “evidence so clear,
    direct and weighty and convincing as to enable the factfinder
    to come to a clear conviction, without hesitancy, of the
    precise facts in issue.” N.J. Div. of Youth & Family Servs. v.
    I.S., 
    996 A.2d 986
    , 1000 (N.J. 2010) (quoting In re Seaman,
    
    627 A.2d 106
    , 100 (N.J. 1993)).Proof of damages can be
    supported by a jury inference that a defendant’s actions
    “reduced the plaintiff’s profits, although by an uncertain
    amount.” Nappe v. Anschelewitz, Barr, Ansell & Bonello,
    
    477 A.2d 1224
    , 1233 (N.J. 1984).
    Based on the trial record, there was ample evidence
    from which a reasonable jury could have found for Avaya on
    the fraud claim. The evidence for the first element –
    fraudulent conduct – is straightforward.      TLI had its
    customers fill out forms requesting login permissions but
    instructed those customers to leave the “Business Partner”
    58
    component of the form blank, to be filled in later by TLI. TLI
    would then insert the name of an authorized Business Partner
    so that Avaya would provide the requested login information.
    TLI therefore willfully misrepresented who was making the
    request for the login credentials and acknowledged the
    materiality of that misrepresentation by confirming that it did
    not want Avaya to find out what they were doing, because
    Avaya would otherwise not provide the logins.
    The evidence also satisfies the second element,
    knowledge, in that it supports a conclusion that TLI knew it
    was operating under false pretenses. The form at issue, by its
    very language, is a request from a customer to Avaya for
    delivery of information to a specifically named Business
    Partner. The form provided that the login Avaya furnished
    would allow “the Business Partner listed above ... to perform
    additions, changes, moves and/or upgrades.” (J.A. 5313.)
    Yet TLI submitted the form knowing full well that the
    “Business Partner listed above” would not be performing
    those tasks, because TLI would be.
    As to the third element, the reasonableness of relying
    on the representation, TLI filled out the form with the name
    and information of an existing, authorized Business Partner.
    A jury could find that Avaya acted reasonably by providing
    access information when it believed such access was being
    delivered to a provider with whom it had an existing contract.
    The final element, damages, is what most concerned
    the District Court. As established above, however, Avaya
    presented strong evidence – sufficient for the clear and
    convincing standard – that every dollar made by TLI in its
    maintenance of Avaya products was necessarily to some
    59
    degree at Avaya’s expense. A jury could have reasonably
    concluded that each time TLI used a fraudulently obtained
    login to win or keep a maintenance contract, that cost Avaya
    profit. As the Supreme Court of New Jersey confirmed in
    Nappe, such an inference is enough to sustain a finding of
    damages, even where the exact amount may be 
    uncertain. 477 A.2d at 1233
    .
    Avaya thus presented sufficient evidence to send the
    fraud claim to the jury, based on TLI’s deceptive login
    requests.
    60
    6.     Breach of Contract
    Finally, we turn to Avaya’s breach of contract claims
    against TLI. As developed at trial, Avaya contended that TLI
    breached two contracts: the 1998 dealer agreement between
    Lucent and TLI, and the 2003 Avaya One agreement that was
    effective until TLI’s participation as a Business Partner was
    terminated.32 In both cases, the District Court did not contest
    the existence of the contract or damages, but instead granted
    judgment as a matter of law on the ground that “Avaya ha[d]
    failed to introduce evidence from which a reasonable jury
    could find that TLI breached either of the contracts.” (J.A.
    210.) Once again, there is not a sound basis for that holding.
    a.     1998 Dealer Agreement
    The 1998 contract’s choice of law provision provides
    that it is governed by Delaware law. In Delaware, the
    elements of a breach of contract claim are: “[1] the existence
    of the contract, whether express or implied; [2] the breach of
    an obligation imposed by that contract; and [3] the resultant
    damage to the plaintiff.” VLIW Tech., LLC v. Hewlett-
    Packard Co., 
    840 A.2d 606
    , 612 (Del. 2003).
    32
    Whereas the customer contracts referenced above in
    Part II.A.2 were for PBX systems, the dealer agreements
    between Avaya and TLI are worded broadly enough to reach
    both the PBX and PDS markets. Insofar as Avaya’s breach of
    contract allegations rely primarily on improper access to
    ODMCs and MSPs, however, the breach of contract claim is
    principally focused on the larger PBX market.
    61
    The signature page of the 1998 agreement evidences a
    contract between Lucent (Avaya’s predecessor) and TLI
    (referred to in the contract as the “Dealer”), satisfying the first
    element of the cause of action. Section 2.8 of the 1998
    agreement provides, in part, as follows:
    Dealer may not market or sell Lucent Products
    to any Lucent BCS Global Account, or … the
    United States Government, and will use its best
    efforts to ensure that Dealer does not market to
    present direct customers of Lucent who are
    under warranty or with existing maintenance
    contracts for Lucent products or to any entity
    that is considering a proposal from Lucent for
    products or maintenance services, except that
    Dealer may respond to a request for competitive
    bids, proposals, or quotations even if Lucent is
    also responding.
    (J.A. 5905 (emphases added).)
    Avaya claims that TLI breached that “best efforts”
    clause by marketing and selling maintenance services to
    existing Lucent/Avaya customers. At trial, Douglas Graham
    admitted that TLI “marketed … to existing Avaya
    maintenance customers” in 2001, while the firm “was
    operating under the terms of the 1998 Lucent dealer
    agreement.” (J.A. 2704.) He also acknowledged a particular
    client to whom TLI had “marketed ... maintenance to replace
    existing Avaya maintenance.” (J.A. 2705.)
    In spite of what is arguably a clear violation of § 2.8 of
    the agreement, the District Court concluded that TLI’s
    62
    conduct “does not constitute a breach” because the Court
    interpreted § 2.8 to prohibit only the marketing of “Lucent
    Products,” a defined term that did not include maintenance.
    (J.A. 212.)       That, however, is an overly cramped
    interpretation of the provision. Although a jury could perhaps
    import the “Lucent Products” language into the “best efforts”
    clause, that clause could just as easily support an
    interpretation that generally bars the marketing of
    maintenance to Lucent/Avaya customers. Indeed, the best
    efforts clause specifically prohibits marketing to
    Lucent/Avaya customers “with existing maintenance
    contracts ... or to any entity that is considering a proposal
    from Lucent for … maintenance services,” which strongly
    suggests that maintenance was part of the prohibition. (J.A.
    5905.) The District Court therefore erred in assuming that
    “no reasonable jury” could have found a breach of § 2.8.
    (J.A. 213.)
    As to the final element, damages, we conclude that the
    same analysis for the earlier causes of action would have
    supported a jury finding that any profit that TLI gained by its
    breach of contract must have come, at least in part, at Avaya’s
    expense. Therefore, we conclude that a jury could reasonably
    have found all three elements of a breach of contract, and
    judgment as a matter of law was not proper.
    b.     2003 Avaya One Agreement
    The choice of law clause in the Avaya One agreement,
    § 18.1, provides that New York law governs. Under New
    York law, the elements of a breach of contract claim are
    similar to Delaware’s: “[1] the existence of a contract, [2] the
    plaintiff’s performance pursuant to the contract, [3] the
    63
    defendant’s breach of his or her contractual obligations, and
    [4] damages resulting from the breach.” Neckles Builders,
    Inc. v. Turner, 
    986 N.Y.S.2d 494
    , 496 (N.Y. App. Div.
    2014).
    The signature page of the Avaya One agreement
    evidences a contract between Avaya and TLI, satisfying the
    first element. Section 7.3 of the Avaya One agreement
    provides, in part, as follows:
    [TLI] agrees not to reverse engineer, decompile
    or disassemble software furnished to it in object
    code form or permit any third party to do so.
    For any software included as part of the
    Licensed Materials which inherently includes
    the capability of being remotely enabled, [TLI]
    expressly agrees that it shall not enable, or
    permit or assist any third party to enable, such
    features or capabilities without Avaya’s express
    written permission.33
    (J.A. 6953.) That obligation was clearly intended to survive
    the termination of the Avaya One agreement.34 Both an
    33
    As an Avaya executive testified at trial, the purpose
    of that provision was “to protect [Avaya’s] software assets
    going forward if there is information that a Business Partner
    gets, [and] also to make sure that nothing gets turned on
    subsequent[ to] termination.” (J.A. 2116.)
    34
    Section 17.6 of the agreement provided that “the
    termination of the Agreement shall not prejudice or otherwise
    affect ... any ... obligations of the parties, such as those arising
    64
    Avaya executive and a systems engineer testified that MSPs
    and the DADMIN logins were capable of being remotely
    enabled.
    The agreement also included, at § 4.1, a general
    morality clause that bound TLI for the duration of the
    agreement:
    [TLI] shall: (a) conduct its business in a manner
    that reflects favorably on the Products and on
    the good name, goodwill and reputation of
    Avaya; (b) avoid deception, misleading or
    unethical practices; and (c) use best efforts to
    promote, market, and further the interest of
    Avaya, its name and Products.
    (J.A. 6951 (emphases added).)
    Although Avaya’s performance – the second element
    of a breach of contract claim – was not part of the District
    Court’s analysis, the record provides sufficient evidence for a
    jury to conclude that Avaya did perform. TLI was operating
    as a Business Partner under the Avaya One agreement from
    its execution until the business relationship between the
    parties was terminated. Douglas Graham acknowledged that
    the relationship was “mutually beneficial” and that, “[a]s an
    Avaya Business Partner ... TLI was authorized by Avaya to
    resell certain Avaya products and services.” (J.A. 2699.)
    under [Section 7], which by their nature continue beyond
    termination of the Agreement and which shall survive such
    termination.” (J.A. 6959.)
    65
    Indeed, Avaya equipment was “by far [the] leading
    manufacturer product that [TLI] sold.” (J.A. 2700.)
    The District Court’s analysis focused on the third
    element – the actual breach of a contractual obligation.
    Avaya’s claim for breach of § 7.3 is straightforward. Insofar
    as MSPs and DADMINs were “licensed Materials which
    inherently include[d] the capability of being remotely
    enabled,” a jury could find that TLI breached its contractual
    obligations when it “enable[d] ... or assist[ed] any third party
    to enable, such features or capabilities without Avaya’s
    express written permission.” (J.A. 6953.) Even though the
    District Court acknowledged that the meaning of those terms
    was “less than perfectly clear,” it nonetheless concluded that
    the term “features and capabilities” unambiguously excluded
    MSPs and DADMIN logins. (J.A. 218-19.) Yet the
    activation of MSPs and use of DADMIN logins allowed
    customers to perform remote maintenance, for which
    customers were willing to pay additional licensing fees,
    suggesting that the customers considered them to be features
    or capabilities. Even if a reasonable jury could have agreed
    with the District Court’s reading of the contract, there was at
    least sufficient ambiguity in the Avaya One agreement that
    the jury could have seen it the other way and agreed with
    Avaya that MSPs and DADMIN logins are “features and
    capabilities,” the unauthorized activation of which by TLI
    amounted to a breach of contractual obligations.
    As to the morality clause in § 4.1, Avaya contended
    that TLI breached its obligations when it began its allegedly
    unethical business practices during the term of the contract, in
    preparation for soliciting maintenance customers away from
    Avaya. Those activities included hacking logins and enlisting
    66
    Business Partners to obtain ODMC access. As early as May
    2003, while still bound by the Avaya One agreement, TLI
    solicited Creswick to “pull ... password[s].” (J.A. 2281.) In
    September, during the contract term, TLI began to seek a
    “discreet Avaya Business Partner ... [to] submit DADMIN
    request forms on our behalf.” (J.A. 5813.) A reasonable jury
    could have concluded that, by engaging Creswick and
    recruiting Business Partners to submit deceptive DADMIN
    login request forms, TLI was violating its contractual
    obligations to “avoid deception [and] misleading or unethical
    practices” and to “use best efforts to promote, market, and
    further the interest of Avaya.” (J.A. 6951.)
    Analysis of damages – the final element of the cause
    of action – was not central to the District Court’s grant of
    judgment as a matter of law. However, the analysis for
    damages is as straightforward as for the tort claims, because
    PBX and PDS maintenance business gained by TLI as a result
    of its breach must have come, to some extent, at Avaya’s
    expense.
    7.     Conclusion
    Based on the foregoing analysis, we conclude that the
    District Court’s grant of judgment as a matter of law was
    erroneous for the four affirmative common law claims that
    Avaya addresses in this appeal.35 We will therefore vacate
    35
    Although our dissenting colleague’s “assessment of
    Avaya’s case-in-chief is the same as the District Court’s”
    (Dissenting Op. at 3-4), he has sufficient “doubt about the
    propriety of the District Court’s decision” that he focuses his
    opinion on other issues (id. at 4). We therefore let our
    67
    the District Court’s judgment and remand for further
    proceedings on those four claims. That does not, however,
    end our inquiry. Given the District Court’s instruction to the
    jury that all of TLI’s conduct was lawful, we must also
    consider whether the several errors associated with the
    District Court’s handling of the common law claims also
    infected the remainder of the trial.
    B.     Prejudice on the Antitrust Verdict
    Avaya, of course, argues that the error did spill over
    into the antitrust verdict. It presents three bases for
    concluding that the judgment as a matter of law prejudiced
    the jury’s consideration of the antitrust counterclaims: first, it
    undermined Avaya’s defense that its responses to TLI’s
    conduct were reasonable and pro-competitive; second, it lent
    false credence to TLI’s assertion that Avaya knew there was
    no truth to its letters (the so-called “FUD” letters described
    above) telling customers that using ISPs would be unlawful;
    and third, it led the District Court to wrongly restrict Avaya’s
    cross-examinations of TLI witnesses. We agree that those
    problems, all resulting from the erroneous grant of judgment
    as a matter of law, did indeed likely affect the antitrust
    verdict.
    1.      General Prejudice to Avaya’s
    Antitrust Defense
    All of the antitrust counterclaims against Avaya were
    presented under the “rule of reason,” which gives effect to the
    analysis of the District Court’s error speak for itself as a
    response to that portion of the Dissent.
    68
    Supreme Court’s instruction that the Sherman Act “only
    means to declare illegal any [restraint] which is in
    unreasonable restraint of trade.” United States v. Trans-
    Missouri Freight Ass’n, 
    166 U.S. 290
    , 327 (1897) (emphasis
    added). “Under this rule, the factfinder weighs all of the
    circumstances of a case in deciding whether a restrictive
    practice should be prohibited as imposing an unreasonable
    restraint on competition.” Cont’l T. V., Inc. v. GTE Sylvania
    Inc., 
    433 U.S. 36
    , 49 (1977). Therefore, limitations on
    Avaya’s ability to explain the reasonableness of its actions
    had the potential to harm its defense.
    For the Sherman Act § 2 monopolization claims, for
    example, TLI had to establish that Avaya’s allegedly
    predatory conduct was performed with monopolistic intent.
    “To prevail on an attempted monopolization claim under § 2
    of the Sherman Act, a plaintiff must prove that the defendant
    (1) engaged in predatory or anticompetitive conduct with (2)
    specific intent to monopolize and with (3) a dangerous
    probability of achieving monopoly power.” Queen City
    Pizza, Inc. v. Domino’s Pizza, Inc., 
    124 F.3d 430
    , 442 (3d
    Cir. 1997) (emphasis added) (internal quotation marks
    omitted). “Liability turns ... on whether valid business
    reasons can explain [a defendant’s] actions.” Eastman Kodak
    Co. v. Image Tech. Servs., Inc., 
    504 U.S. 451
    , 483 (1992)
    (internal quotation marks omitted). As the District Court
    instructed the jury, “acts or practices that result in the
    acquisition or maintenance of monopoly power must
    represent something more than the conduct of business that is
    part of the normal competitive process” and must be actions
    that are “taken for no legitimate business reasons.” (J.A.
    621.) Insofar as Avaya was limited in explaining why its
    69
    actions were not predatory or lacked a monopolistic intent,
    those limitations would of course harm its defense.36
    The District Court’s instructions in light of its
    erroneous Rule 50 decision on the common law claims may
    well have affected the jury’s assessment of the reasonableness
    and purpose of Avaya’s actions. The jury was prevented
    from deciding the antitrust claims and the common law
    claims in concert and from evaluating whether TLI’s
    allegedly tortious conduct provided a legitimate business
    justification for the things Avaya’s did. Specifically, the
    Court instructed the jury that
    Avaya’s claim[s] against TLI[] ... have been
    resolved and are no longer before you. ...
    In Avaya’s direct claims against all the
    defendants, Avaya asserted that [TLI’s] use of
    36
    Moreover, as we explain in more detail below, under
    the specific theory of antitrust liability pressed by TLI, if
    Avaya’s sales contracts had established that using
    independent service providers was prohibited, then any
    remedy to infirmities in that arrangement would lie “in
    contract, not under the antitrust laws.” Queen City 
    Pizza, 124 F.3d at 441
    .       Therefore, to the extent that Avaya’s
    interpretation of its customer contracts was correct, that
    would have added a very potent weapon to Avaya’s arsenal to
    combat the specific theory of antitrust liability argued by TLI.
    But Avaya was precluded from making that argument
    because the District Court erroneously adopted a definitive
    construction of those contracts, as a matter of law, in service
    of its Rule 50 decision.
    70
    and access to the maintenance software
    embedded in the Avaya PBXs and PDSs, such
    as the on-demand maintenance commands, was,
    for a variety of reasons, unlawful. I now
    instruct you that [TLI’s] use of and access to
    such maintenance software may not be
    considered by you as unlawful when deciding
    [TLI’s] claims against Avaya asserted in the
    counterclaim. To the extent Avaya has alleged
    that TLI[] engaged in illegal or unlawful
    conduct, in connection with its business
    operations, such allegations should be
    disregarded.
    (J.A. 4739 (emphasis added).)
    Not only did the District Court so instruct the jury, but
    TLI itself repeatedly emphasized that instruction in its closing
    argument in order to undercut Avaya’s defense that there was
    a reasonable business justification for its actions. Consider
    this passage from TLI’s summation:
    When TLI started to compete with Avaya, it
    had the right to do so; and, yes, [the District
    Court] will instruct you tomorrow, you should
    not consider TLI’s ... use of and access to the
    maintenance software that’s embedded in these
    Avaya PBX systems and dialers, do not
    consider it in any way unlawful. And this is
    critically important for you to understand. You
    are not to consider TLI’s actions in that regard
    unlawful.
    71
    (J.A. 4732.)37
    The District Court’s erroneous instruction, combined
    with TLI’s repeated hammering of the point, highlights how
    important the lawfulness or unlawfulness of TLI’s actions
    could have been to the jury’s deliberations. Avaya’s entire
    affirmative case alleged that TLI’s conduct was tortious and
    in breach of contractual obligations. If true, Avaya’s
    defensive response could be seen as substantially more
    reasonable, and its intentions substantially less predatory. By
    instructing the jury that it could not consider TLI’s conduct to
    be unlawful – an instruction premised on the flawed grant of
    judgment as a matter of law – the District Court improperly
    prevented the jury from weighing Avaya’s defenses in light of
    the rule of reason standard for both the § 1 and § 2 Sherman
    Act claims.38
    37
    At least twice more, TLI strongly emphasized the
    importance of the District Court’s jury instructions. For
    instance, it told the jury that “[w]hen TLI started to compete
    with Avaya, it had every right to do so. TLI’s use and access
    to maintenance software that’s embedded in these systems,
    you should not consider to be unlawful. You will hear that
    instruction from the judge tomorrow.” (J.A. 4733.) Later, it
    reminded the jury: “Again, you will be instructed by the
    Court tomorrow, that you are not to consider TLI’s access to
    or use of the maintenance software, including MSPs and
    ODMs, called ODMCs and maintenance software
    permissions, as in any way unlawful use of that maintenance
    software.” (J.A. 4734.)
    38
    As we read the Dissent, its objection to our
    conclusion comes down to its premise that “Avaya had ample
    72
    opportunity to present the jury with legitimate and
    procompetitive defenses for its actions.” (Dissenting Op. at
    10.) To be sure, Avaya mounted a vigorous defense
    notwithstanding the limitations it faced as a result of the Rule
    50 ruling, but we lack the Dissent’s confidence that it is
    “highly probable that the error did not affect the outcome of
    the case.” Glass v. Phila. Elec. Co., 
    34 F.3d 188
    , 191 (3d Cir.
    1994) (quotation marks and citation omitted). A jury may
    well have evaluated Avaya’s conduct differently if Avaya
    were simply enforcing its contractual rights or combating
    tortious activity, as TLI itself recognized by its repeated
    emphasis in its summation that its actions could not be
    considered unlawful. The Dissent betrays the importance of
    the lawfulness determination when it says that Avaya’s
    “defenses did not depend on whether TLI’s conduct was so
    egregious as to be against the law.” (Id.) The special
    egregiousness of unlawful conduct is precisely the argument
    that Avaya wanted to make – and was deprived from making
    – to the jury.
    This is also where the Dissent’s “David and Goliath”
    analogy breaks down. Avaya was certainly the bigger
    competitor, but TLI was no plucky little company armed only
    with the business equivalent of a sling and a few stones. It
    was a sophisticated and aggressive company, which, at least
    according to Avaya and a great deal of the evidence at trial,
    was prepared to, and did, engage in what even the Dissent
    acknowledges were “deceitful and/or unethical” business
    methods. (Id. at 2.) Since those methods were such that the
    jury could have found them unlawful, the Rule 50 error was
    not harmless.
    73
    2.     “Fear, Uncertainty, and Doubt”
    Letters
    Beyond the general infection of the jury’s
    consideration of the reasonableness of Avaya’s actions, the
    District Court’s grant of judgment as a matter of law also
    undercut a specific portion of Avaya’s antitrust defense.
    Among the evidence put forward by TLI to prove
    predatory conduct were the FUD letters. Those letters told
    customers that MSPs “are not available to customers of
    Unauthorized Service Providers,” that “Unauthorized
    Maintenance Service Providers do not have rights to receive
    [MSP] benefits, nor do they have rights to use Avaya logins,”
    and that “[u]se of MSPs, or any Avaya Login ... without a
    license from Avaya, is an infringement of Avaya’s
    intellectual property rights.” (J.A. 7303-04.)
    Whether those letters could constitute monopolistic
    conduct turned on whether they were true. As the District
    Court instructed the jury, “the law does not allow [TLI’s]
    injury to be based on ... Avaya’s dissemination of truthful
    statements.” (J.A. 621.) The jury’s assessment of the letters’
    truthfulness was surely influenced by the District Court’s
    instruction that TLI’s “use of and access to such maintenance
    software may not be considered by you as unlawful” and that
    “[t]o the extent Avaya has alleged that TLI[] engaged in
    illegal or unlawful conduct, in connection with its business
    operations, such allegations should be disregarded.” (J.A.
    615.)
    That instruction all but told the jury that the letters
    were false in their allegation that TLI’s access was unlawful.
    74
    TLI’s trial counsel then connected those closely adjacent dots
    when he took advantage of the instruction to argue to the jury
    that Avaya’s FUD letters were untruthful and therefore
    monopolistic:
    Even though it acknowledged that it had no
    legal basis to do so,[39] Avaya sent FUD letters
    to TLI’s customers ... .
    As the Court will instruct you tomorrow, you
    are not to consider ... TLI’s access to the
    maintenance commands or the maintenance
    software as unlawful, but Avaya’s FUD
    campaign simply did not convey truthful
    information.
    (J.A. 4736.)40
    39
    We have been shown nothing in the record
    suggesting that Avaya acknowledged that it had “no legal
    basis” to send the so-called FUD letters. To the contrary,
    Avaya’s entire affirmative case relied in large part on a belief
    that TLI’s unauthorized provision of maintenance services did
    lead customers to breach their contracts with Avaya. On
    appeal, Avaya continues to argue that the FUD letters were
    truthful.
    40
    The Dissent contends that “[e]ven if the jury had not
    been instructed that unauthorized access to Avaya software
    was not illegal, it is unlikely that it would have reached a
    different verdict.” (Dissenting Op. at 13.) The Dissent says
    that Avaya seemed to concede that the FUD letters included
    some “over-the-top” prose (id.), but be that as it may, the
    75
    3.     Interference with Defense and Cross-
    Examination
    Avaya also contends that the District Court’s grant of
    judgment as a matter of law hindered its ability to present
    evidence in its defense against the antitrust claims. It points
    to two examples in particular.
    First, during Avaya’s cross-examination of TLI’s
    CEO, Avaya’s counsel asked about how TLI got access to
    Avaya brand PBX systems. At a sidebar, the District Court
    told counsel that, “[i]f you’re trying to tell the jury they’re
    illegal, I have a problem with that.” (J.A. 4440.) The Court
    did allow the line of questions but under the restriction that
    counsel could not imply that TLI’s actions were unlawful.
    Second, when Avaya was examining its own
    economics expert, it presented evidence that restrictions it
    placed on its Business Partners actually ended up “clearing
    the field” in a way that advantaged TLI competitively.41
    degree to which those letters were legitimate surely depended
    on the truth of the legal assertions in them. If Avaya was
    correct in its assertions that unauthorized access was unlawful
    – a question taken away from the jury by virtue of the Rule 50
    decision – then the letters arguably contain defensible
    statements of law. That could make a world of difference to a
    jury in evaluating the truthfulness and competitive legitimacy
    of the letters.
    41
    The basis for the field-clearing argument was that
    because Avaya restricted its Business Partners from
    competing with it for maintenance business, when TLI sought
    76
    Before the Rule 50 decision, the expert was planning to
    include analysis predicated on the illegality of TLI’s conduct,
    but – after the judgment as a matter of law – the District
    Court reminded counsel in a sidebar to “[s]tay away from
    trying to ... contradict anything I’ve already decided,” in
    reference to the Rule 50 decision. (J.A. 4587.)
    Those specific examples speak to a broader point.
    They highlight that, if Avaya had been able to argue that
    TLI’s conduct was unlawful, that argument would likely have
    been a key and repeated part of its defense to the antitrust
    claims. Each argument by TLI’s counsel to the contrary
    could have been met with a forceful response. Avaya’s claim
    that it was “hamstrung in its ability to justify its supposedly
    anticompetitive conduct” is therefore a fair and accurate one.
    (Third Step Br. at 19.)42
    to lure customers from Avaya, it did not have to compete with
    any of those Business Partners, who were precluded from
    seeking that business. In that way, the expert opined, TLI
    benefited from much of the allegedly anticompetitive conduct
    over which it filed suit because that conduct restricted TLI’s
    competition as much as it did Avaya’s.
    42
    The Dissent suggests that any limitations placed on
    Avaya’s defense as a result of the Rule 50 ruling were merely
    “rhetorical,” and that being able to argue the illegality of
    TLI’s conduct “would not have changed the substance of
    Avaya’s procompetitive-justification argument.” (Dissenting
    Op. at 12.) We disagree. It is one thing to explain to a jury
    that sharp-elbowed tactics were taken to retaliate against
    aggressive but completely lawful activities of a competitor. It
    is altogether different to be able to argue that the restraints of
    77
    4.     Harmless Error Analysis
    Having concluded that the judgment as a matter of law
    on Avaya’s common law claims was an error, and that that
    error likely affected the jury’s consideration of the antitrust
    claims, we must now consider whether that effect was
    harmless. “An error will be deemed harmless only if it is
    highly probable that the error did not affect the outcome of
    the case,” and, in that same vein, an error cannot be said to be
    harmless unless there is a high probability “that the result
    would have been the same had the jury been correctly
    instructed.” Hill v. Reederei F. Laeisz G.M.B.H., Rostock,
    
    435 F.3d 404
    , 411 (3d Cir. 2006) (internal quotation marks
    omitted). We have held, when interpreting this “highly
    probable” standard, that an error is not harmless if it could
    have “reasonably ... affected the outcome of the trial,” 
    id. at 411,
    or if the jury “quite possibly” relied on an erroneous
    instruction, see Hirst v. Inverness Hotel Corp., 
    544 F.3d 221
    ,
    228 (3d Cir. 2008).
    In this case, we cannot say that it was “highly
    probable” that the District Court’s erroneous Rule 50 decision
    and resulting erroneous jury instruction about the lawfulness
    of TLI’s conduct did not affect the outcome of the antitrust
    claims.43 On the contrary: we think it probable that they did
    trade at issue were necessary to enforce Avaya’s contractual
    rights and to deter fraudulent and tortious interference with
    Avaya’s legitimate business interests.
    43
    The Dissent would not even reach the question of
    whether the District Court’s erroneous Rule 50 order infected
    the antitrust verdict, on the ground that Avaya forfeited any
    78
    affect the outcome. The judgment as a matter of law, the
    concordant limitations on Avaya’s antitrust defense, and the
    ultimate jury instruction about lawfulness all seriously
    hampered Avaya’s ability to argue that its conduct was a
    argument of spill-over prejudice. That position seems to us to
    result from the Dissent’s separate (and, in our estimation,
    incorrect) view that any prejudicial effect on the jury’s
    consideration of the antitrust counterclaims was tangential
    and minor. We agree with our dissenting colleague that, “[i]f
    a claim of error is unaccompanied by developed argument, it
    is forfeited.” (Dissenting Op. at 6 (internal quotation marks
    and citation omitted).) In this case, however, the claim of
    error – that the District Court’s Rule 50 decision was
    improper – was indisputably fully briefed and argued.
    Avaya’s position that the erroneous Rule 50 ruling tainted the
    antitrust verdict was made as a request for a particular form of
    relief to correct that error. The request was brief but the
    brevity is unsurprising, given how inextricably linked
    Avaya’s rule of reason antitrust defense was to its claims that
    TLI’s actions were unlawful. Avaya could reasonably have
    expected TLI’s answer simply to contest Avaya’s claim of
    error as to the Rule 50 ruling, as TLI in fact did contest at
    length. As it happened, however, TLI also raised a separate
    argument, as an alternative basis to affirm, that any error was
    harmless as to the antitrust verdict. Avaya then provided a
    rebuttal to that assertion of harmlessness with exactly the kind
    of responsive argumentation we would expect in a reply brief.
    Cf. Becker v. ARCO Chem. Co., 
    207 F.3d 176
    , 205 (3d Cir.
    2000) (considering and rejecting a harmless error argument
    raised for the first time by the appellee at oral argument and
    only then countered by the appellant).
    79
    justifiable and reasonable response to TLI’s underhanded
    methods of acquiring Avaya’s proprietary business
    information. That TLI used the District Court’s errors to
    pound home its own case only compounded the problem and
    further undermines our confidence in the verdict. Because
    the errors “quite possibly” affected the judgment, we must
    vacate it. 
    Hirst, 544 F.3d at 228
    .44
    C.     Antitrust Issues
    Avaya does not simply seek vacatur, however. It
    argues that we should reverse the judgment and hold that it is
    entitled to judgment on the antitrust counterclaims because
    TLI adduced insufficient evidence to support them. We begin
    our analysis of that argument by reviewing how the antitrust
    laws treat product tying. We then turn to Avaya’s claim-
    specific contentions and conclude that the PBX attempted
    monopolization counterclaim is legally invalid for PBXs sold
    after 2008 and that the PDS tying counterclaim must fail as a
    matter of law.
    1.     Tying in Antitrust Law
    TLI’s antitrust counterclaims against Avaya are based
    on an allegedly unlawful use of tying to restrain and
    monopolize the market for PBX and PDS maintenance
    services. “[A] tying arrangement may be defined as an
    agreement by a party to sell one product [or service] but only
    44
    The parties also dispute the propriety of the
    injunctive relief ordered by the District Court. Because we
    will vacate the verdict and judgment of liability, we must also
    vacate the resulting injunction.
    80
    on the condition that the buyer also purchases a different (or
    tied) product [or service], or at least agrees that he will not
    purchase that product [or service] from any other supplier.”
    Northern Pacific Ry. Co. v. United States, 
    356 U.S. 1
    , 5-6
    (1958). For a pair of products or services to be distinct, and
    therefore capable of being tied together, “there must be
    sufficient consumer demand so that it is efficient for a firm to
    provide [them] separately.” 
    Kodak, 504 U.S. at 462
    . Tying
    can support a Sherman Act claim either under § 1, as an
    unlawful restraint on trade, or under § 2, as an unlawful act of
    monopolization or attempted monopolization. See Phillip E.
    Areeda & Herbert Hovenkamp, Fundamentals of Antitrust
    Law (“Fundamentals”) § 17.01, at 17-13 (4th ed. Supp.
    2015); see also 15 U.S.C. §§ 1-2.45 Under the antitrust
    theories presented by TLI, Avaya unlawfully tied its PBX and
    PDS systems to maintenance services by conditioning access
    to equipment and software on the purchase of such services
    from Avaya or its Business Partners.
    Not all ties are illegal, however. To declare otherwise
    would risk making practically every product the subject of an
    antitrust suit, because, in theory at least, most any product can
    be deconstructed into component parts that could be sold
    separately. For that reason, “[i]t is clear ... that every refusal
    to sell two products separately cannot be said to restrain
    45
    TLI secured verdicts against Avaya under both §§ 1
    and 2 of the Sherman Act. Section 1 declares illegal “[e]very
    contract, combination ..., or conspiracy, in restraint of trade or
    commerce.” 15 U.S.C. § 1. Section 2 makes unlawful any
    act to “monopolize, or attempt to monopolize, or combine or
    conspire ... to monopolize any part of the trade or commerce.”
    15 U.S.C. § 2.

    competition.” Jefferson Par. Hosp. Dist. No. 2 v. Hyde, 
    466 U.S. 2
    , 11 (1984) partially abrogated on other grounds by Ill.
    Tool Works Inc. v. Indep. Ink, Inc., 
    544 U.S. 28
    (2006).
    Instead,
    the essential characteristic of an invalid tying
    arrangement lies in the seller’s exploitation of
    its control over the tying product to force the
    buyer into the purchase of a tied product that
    the buyer either did not want at all, or might
    have preferred to purchase elsewhere on
    different terms. When such “forcing” is present,
    competition on the merits in the market for the
    tied item is restrained and the Sherman Act is
    violated.
    
    Id. at 12.
    Therefore, “[w]hen ... the seller does not have ... the
    kind of market power that enables him to force customers to
    purchase a second, unwanted product in order to obtain the
    tying product, an antitrust violation can be established only
    by evidence of an unreasonable restraint on competition in the
    relevant market.” 
    Id. at 17-18.
    In this case, nobody contends that the primary market
    for PBX and PDS systems is anything other than competitive,
    or that Avaya’s main competitors in that market – large firms
    such as Cisco, Siemens, and Microsoft – cannot use prices to
    discipline Avaya in that primary market. As to the primary
    market, then, TLI’s position is not that Avaya’s “share of the
    market is high” or that it “offers a unique product that
    competitors are not able to offer.” 
    Id. at 17.
    Rather, TLI has
    proceeded under a specialized theory of tying developed in a
    Supreme Court case called Eastman Kodak Company v.
    82
    Image Technical Services, Inc., 
    504 U.S. 451
    (1992). Review
    of the Kodak opinion and our Court’s elaboration of its
    principles is essential, then, because TLI’s counterclaims rise
    or fall based on whether they comport with a Kodak theory of
    antitrust liability.
    a.     The Kodak Theory of Antitrust
    Tying Liability
    Kodak presented the Supreme Court with a situation
    similar to the one before us, consisting of a primary market
    for complex durable goods and an aftermarket for
    maintenance service. Kodak sold photocopier equipment, as
    well as maintenance service and replacement parts. 
    Id. at 455.
    The parts were of proprietary design and were not
    interchangeable with other manufacturers’ parts. 
    Id. at 456-
    57. Kodak sold both parts and service, using different
    contract arrangements to charge different prices to different
    customers. 
    Id. at 457.
    When Kodak attempted to prevent the
    sale of its parts to independent maintenance service providers
    – thereby restricting their ability to service Kodak machines –
    a group of those independent providers filed suit, alleging
    unlawful tying of parts and service in violation of §§ 1 and 2
    of the Sherman Act. 
    Id. at 458-59.
    On ultimate appeal from the district court’s grant of
    summary judgment for Kodak, the Supreme Court ruled that
    the plaintiffs had put forward a strong enough case to proceed
    to trial. The Court accepted Kodak’s argument that the
    primary equipment market was competitive, 
    id. at 465
    n.10,
    but it nonetheless ruled that the plaintiffs could proceed under
    a § 1 tying theory of antitrust liability. It refused to endorse
    Kodak’s assertion that competition in the primary market
    83
    would necessarily discipline the maintenance aftermarket,
    preferring not to adopt “[l]egal presumptions that rest on
    formalistic distinctions rather than actual market realities.”
    
    Id. at 466.
    Instead, the Court insisted on a context-specific
    factual analysis of whether “the equipment market does
    discipline the aftermarkets so that [both] are priced
    competitively overall, or that any anti-competitive effects of
    Kodak’s behavior are outweighed by its competitive effects.”
    
    Id. at 486.
    “The fact that the equipment market imposes a
    restraint on prices in the aftermarkets” does not, on its own,
    “disprove[] the existence of power in those markets.” 
    Id. at 471
    (citation omitted).
    In explaining how a seller facing a competitive
    primary equipment market could nonetheless exercise market
    power in the parts and maintenance aftermarkets, the Court
    expounded a theory whereby high information and switching
    costs would allow the seller to exploit customers who had
    already purchased the equipment and were then “locked in” to
    the aftermarkets. 
    Id. at 476.
    It explained that “[l]ifecycle
    pricing of complex, durable equipment is difficult and
    costly,” and that the information needed for such lifecycle
    pricing “is difficult – some of it impossible – to acquire at the
    time of purchase.” 
    Id. at 473.
    Because “[a]cquiring the
    information is expensive[, i]f the costs of service are small
    relative to the equipment price, ... [consumers] may not find it
    cost efficient to compile the information.” 
    Id. at 474-75.
    Additionally, competitors may not provide that information,
    either because they do not have it themselves or because they
    may wish to collusively engage in the same behavior with
    their own customers so that “their interests would [not] be
    advanced by providing such information to consumers.” 
    Id. 84 at
    474 & n.21 (citation omitted). Customers’ information
    limitations could be paired with high switching costs so that
    consumers who already have purchased the
    equipment, and are thus “locked in,” will
    tolerate some level of service-price increases
    before changing equipment brands. Under this
    scenario, a seller profitably could maintain
    supracompetitive prices in the aftermarket if the
    switching costs were high relative to the
    increase in service prices, and the number of
    locked-in customers were high relative to the
    number of new purchasers.
    
    Id. at 476.
    In other words, tying liability may exist in an
    aftermarket where the seller can exploit customers who have
    already purchased the equipment and cannot easily shift to
    another brand.
    The Supreme Court also posited that the threat of
    anticompetitive exploitation of aftermarkets in light of high
    information and switching costs would be particularly severe
    in cases where the seller could engage in price discrimination,
    i.e., charging different prices to different types of consumers.
    With respect to information costs, “if a company is able to
    price discriminate between sophisticated and unsophisticated
    consumers, the sophisticated will be unable to prevent the
    exploitation of the uninformed.” 
    Id. at 475.
    With respect to
    switching costs, “if the seller can price discriminate between
    its locked-in customers and potential new customers,” it can
    exploit locked-in customers with supracompetitive
    aftermarket prices while simultaneously charging low prices
    to new customers. 
    Id. at 476.
    Those forms of price
    85
    discrimination could allow a savvy monopolistic seller to
    create a market tiered like a pyramid. While charging lower
    lifecycle prices to sophisticated customers in the primary
    market, the seller could dupe low-information customers into
    paying a deceptively low upfront cost for the equipment, to
    lock them in due to high switching costs and set them up for
    supracompetitive prices in the aftermarkets for parts and
    service. In the meantime, it could continue to make a normal
    competitive profit from sales to sophisticated new customers
    by charging them lower lifecycle prices through lower-priced
    long-term contracts. Price discrimination thus allows a seller
    to run a multi-tier market dividing more sophisticated
    consumers from less sophisticated ones, while lock-in snares
    the unsophisticated customers once the proverbial trap has
    been sprung.
    Not only was that theory sufficient to support § 1
    liability, the Court also held that it could support § 2 liability
    for unlawful monopolization. In that analysis, the Court
    incorporated the § 1 analysis for whether the equipment
    market and the service and parts aftermarkets were distinct
    for antitrust purposes. 
    Id. at 481.
    It was comfortable with
    defining a single-brand market as relevant for antitrust
    purposes as long as such a market was justified by “the
    choices available to ... equipment owners,” as “determined ...
    after a factual inquiry into the ‘commercial realities’ faced by
    consumers.” 
    Id. at 482
    (quoting United States v. Grinnell
    Corp., 
    384 U.S. 563
    , 572 (1966)). A successful plaintiff had
    to prove more, however, to succeed on a § 2 claim, because
    simply proving monopoly power in the aftermarket was not
    enough. A § 2 claim additionally requires showing the use of
    that monopoly power “to foreclose competition, to gain a
    competitive advantage, or to destroy a competitor.” 
    Id. at 86
    482-83 (quoting United States v. Griffith, 
    334 U.S. 100
    , 107
    (1948)). Therefore, in defending against a § 2 claim, the
    seller has the opportunity to justify its actions so that
    “[l]iability turns ... on whether ‘valid business reasons’ can
    explain [its] actions.” 
    Id. at 483
    (quoting Aspen Skiing Co. v.
    Aspen Highlands Skiing Corp., 
    472 U.S. 585
    , 605 (1985)).
    The Court was willing to consider as valid business reasons
    both controlling inventory costs and ensuring high quality
    maintenance service, but it did not consider the record in
    Kodak as sufficient to warrant summary judgment. 
    Id. at 483
    -86.
    b.    Third Circuit Elaboration of
    Kodak
    Since Kodak, our Court has had the opportunity to
    develop that case’s theory of antitrust liability, most notably
    in a pair of cases called Queen City Pizza, Inc. v. Domino’s
    Pizza, Inc., 
    124 F.3d 430
    (3d Cir. 1997), and Harrison Aire,
    Inc. v. Aerostar International, Inc., 
    423 F.3d 374
    (3d Cir.
    2005).
    In Queen City Pizza, we considered a Kodak-style
    claim by a group of franchisees against Domino’s Pizza,
    alleging that Domino’s had used its monopoly power over the
    market for franchise rights and proprietary pizza dough to
    restrain trade in the market for approved pizza 
    supplies. 124 F.3d at 434
    . We affirmed the district court’s dismissal of the
    claims under Federal Rule of Civil Procedure 12(b)(6)
    because we did not consider the contractual requirement for
    franchisees to purchase pizza ingredients from Domino’s to
    implicate the concerns raised in Kodak. 
    Id. at 444.
    We
    observed “that Domino’s approved supplies and ingredients
    87
    are fully interchangeable in all relevant respects with other
    pizza supplies” so that they were not unique in the way that
    Kodak parts were. 
    Id. at 440.
    The plaintiffs were not,
    therefore, forced to purchase approved supplies because of
    the uniqueness of any Domino’s goods, but instead only
    “because they [were] bound by contract to do so.” 
    Id. at 441.
    In distinguishing that contractual obligation from the Kodak
    situation, we explained that, where the defendant’s forcing
    power “stems not from the market, but from plaintiffs’
    contractual agreement ..., no claim will lie.”46 
    Id. at 443.
    “If
    46
    In Queen City Pizza, we talked, in part, of the
    defendant forcing “plaintiffs to purchase the ... tying
    
    product.” 124 F.3d at 443
    (emphasis added). That language
    was a result of the idiosyncratic nature of one of the tying
    theories alleged in that case. Under that theory, the primary
    market was for restaurant franchise agreements, which in turn
    contractually bound franchisees to purchase the alleged
    “tying” product, fresh dough. The franchisees contended that
    Domino’s “refused to sell fresh dough to [them] unless [they]
    purchased other ingredients and supplies from Domino’s,” 
    id. at 434,
    so that the “other ingredients and supplies” were the
    “tied” product.
    The analogy here would be an argument that the
    primary market was for PBX systems, which “forced” the
    purchase of ODMCs and MSPs as the “tying” products,
    which were in turn allegedly used to force purchase of
    maintenance as the “tied” service. No matter how many
    intermediate steps are alleged, however, in the end our
    concern is whether the defendant forced purchases of a tied
    product using power in some distinct market. Jefferson
    
    Parish, 466 U.S. at 12
    . Queen City Pizza stands for the
    proposition that if the supposed forcing is entirely the result
    88
    Domino’s ... acted unreasonably when ... it restricted
    plaintiffs’ ability to purchase supplies from other sources,
    plaintiffs’ remedy, if any, is in contract, not under the
    antitrust laws.” 
    Id. at 441.
    We also emphasized in Queen City Pizza that “[t]he
    Kodak case arose out of concerns about unilateral changes in
    Kodak’s parts and repairs policies.” 
    Id. at 440.
    Because
    Kodak’s change in policy against independent maintenance
    providers “was not foreseen at the time of sale, buyers had no
    ability to calculate these higher costs at the time of purchase
    and incorporate them into their purchase decision.” 
    Id. The Domino’s
    franchisees, on the other hand, “knew that
    Domino’s Pizza retained significant power over their ability
    to purchase cheaper supplies from alternative sources because
    that authority was spelled out in ... the ... franchise
    agreement,” so the “franchisees could assess the potential
    costs and economic risks at the time they signed the franchise
    agreement.” 
    Id. If the
    franchisees found the contractual
    requirements “overly burdensome or risky at the time they
    were proposed, [they] could have purchased a different form
    of restaurant, or made some alternative investment,” 
    id. at 441,
    so that the transaction was “subjected to competition at
    the pre-contract stage,” 
    id. at 440.
    We thus characterized
    Kodak as concerned largely with the threat of unfair surprise
    for customers in the aftermarket, a threat ameliorated if the
    aftermarket terms were made clear in a primary market
    contract.
    of a transparent contractual agreement, then that is not the
    concern of the antitrust laws. A plaintiff cannot avoid that
    outcome merely by crafting a complaint to allege
    intermediate steps.
    89
    In Harrison Aire, our Court’s second major case
    elaborating Kodak, we affirmed summary judgment against
    the Kodak-style claims of a hot air balloon operator that
    alleged that the balloon manufacturer had monopolized the
    aftermarket for replacement balloon fabric by tying the
    purchase of its own branded fabric to its 
    balloons. 423 F.3d at 379
    , 386. We explained that, in general, “[i]f the primary
    market is competitive, a firm exploiting its aftermarket
    customers ordinarily is engaged in a short-run game – for
    when buyers evaluate the ‘lifecycle’ cost of the product, the
    cost of the product over its full service life, they will shop
    elsewhere.” 
    Id. at 38
    2. The Kodak case is an exception to
    that general rule, based on a “market failure” in which
    “lifecycle pricing information is particularly difficult or
    impossible for primary market customers to acquire, as in the
    case of a unilateral change in aftermarket policy targeting
    ‘locked in’ customers.” 
    Id. We emphasized
    that “Kodak
    does not transform every firm with a dominant share of the
    relevant aftermarket into a monopolist,” and that a Kodak-
    style “plaintiff must produce ‘hard evidence dissociating the
    competitive situation in the aftermarket from activities
    occurring in the primary market.’” 
    Id. at 38
    3 (quoting SMS
    Sys. Maint. Servs., Inc. v. Digital Equip. Corp., 
    188 F.3d 11
    ,
    17 (1st Cir. 1999)).
    In evaluating the evidence in Harrison Aire, we
    cautioned that, although “[o]ne important consideration is
    whether a unilateral change in aftermarket policy exploits
    locked-in customers,” 
    id. at 383,
    “an ‘aftermarket policy
    change’ is not the sine qua non of a Kodak claim,” 
    id. at 384.
    Other factors to consider include “evidence of (1)
    supracompetitive pricing, (2) [the seller’s] dominant share of
    the relevant aftermarket, (3) significant information costs that
    90
    prevent[] lifecycle pricing, and (4) high ‘switching costs’ that
    serve[] to ‘lock in’ [the seller’s] aftermarket customers.” 
    Id. Applying those
    factors to the specific circumstances of the
    Harrison Aire case, we concluded that “[n]either information
    costs nor a unilateral change in aftermarket policy prevented
    [the plaintiff] from shopping for competitive lifecycle balloon
    prices when it purchased the ... balloon at issue.” 
    Id. at 38
    4-
    85.     Without “other evidence dissociating competitive
    conditions in the primary balloon market from conditions in
    the aftermarket for replacement fabric,” it was “clear that [the
    plaintiff] got precisely the balloon and the aftermarket fabric
    that it bargained for in the competitive primary market.” 
    Id. at 38
    5.        Therefore, summary judgment against the
    monopolization claim was appropriate.47
    c.     Synthesizing the Kodak Case
    Law
    Kodak makes clear that, in certain limited
    circumstances, a competitive primary market will not insulate
    a defendant from antitrust liability. But neither that case nor
    our subsequent case law overturns the more general principle
    that a plaintiff’s theory of antitrust liability must be
    economically plausible. Thus, in the summary judgment
    context, “‘antitrust law limits the range of permissible
    47
    We also affirmed summary judgment against the § 1
    tying claim raised in Harrison Aire because “[t]ying requires
    appreciable economic power in the tying product market,”
    and the plaintiff “fail[ed] to produce any evidence of
    appreciable market power in the tying product market” for hot
    air 
    balloons. 423 F.3d at 385
    (citations and internal quotation
    marks omitted).
    91
    inferences’ that can be drawn ‘from ambiguous evidence.’”
    Harrison 
    Aire, 423 F.3d at 380
    (quoting Matsushita Elec.
    Indus. Co. v. Zenith Radio Corp., 
    475 U.S. 574
    , 588 (1986)).
    That “higher threshold” for summary judgment “is
    imposed in antitrust cases to avoid deterring innocent conduct
    that reflects enhanced, rather than restrained, competition.”
    In re Flat Glass Antitrust Litig., 
    385 F.3d 350
    , 357 (3d Cir.
    2004). As the Supreme Court put it plainly in Kodak itself,
    “[i]f [a] plaintiff’s theory is economically senseless, no
    reasonable jury could find in its favor, and summary
    judgment should be 
    granted.” 504 U.S. at 468-69
    . The
    requirement that a plaintiff make out an economically
    coherent theory of antitrust liability applies just as much to
    the pleading stage, where, to “make a § 1 claim,” a plaintiff
    must “identify[] facts that are suggestive enough to render a
    § 1 [violation] plausible,” with sufficient “context” to “raise[]
    a suggestion” of unlawful anticompetitive conduct. Bell Atl.
    Corp. v. Twombly, 
    550 U.S. 544
    , 556-57 (2007). The
    requirement that a plaintiff provide an economically plausible
    theory for its antitrust claims applies no less at trial than when
    a case is resolved by summary judgment or on the pleadings.
    With that in mind, we do not read – and have never
    read – Kodak to modify the requirement that a plaintiff in a
    tying case prove that the defendant has market power
    sufficient “to force a purchaser to do something that he would
    not do in a competitive market.” Jefferson 
    Parish, 466 U.S. at 14
    . In general, we expect a vibrant and competitive
    primary market to discipline and restrain power in related
    aftermarkets. What Kodak stands for is the principle that
    there can be some exceptions to that expectation, when a
    plaintiff can produce a plausible economic theory of market
    92
    failure, supported by sufficient evidence. In evaluating the
    issues in this case, we must consider just how broadly that
    Kodak exception should be read.
    A leading antitrust treatise seems to suggest that
    Kodak should be read as confined to the lock-in situation that
    was that opinion’s focus. As that treatise distills the Kodak
    analysis: “Kodak could exploit locked-in customers with
    supracompetitive prices only if it could profitably (1)
    dispense with sophisticated new customers or (2) could
    discriminatorily overcharge only those existing customers
    whose exploitation would not affect new sales.” Areeda &
    Hovenkamp, Fundamentals, supra, § 5.12, at 5-102 (Supp.
    2016).48 Those conditions will rarely obtain, and “[m]uch
    48
    As that treatise explains those two elements in
    greater detail:
    when a defendant has no power in the [primary]
    market,       it   cannot     profitably     charge
    supracompetitive prices for unique [aftermarket
    products] to “locked in” users unless:
    1. it can profitably abandon selling new
    machines to sophisticated new
    customers who would understand that
    the machine’s cost is the sum of its
    nominal price plus the excess
    [maintenance] charges later ...; or
    2. it can price discriminate by
    identifying and overcharging only
    unsophisticated users and thus
    assuring competitive ... prices for
    new, sophisticated customers.
    93
    more typically, high aftermarket prices are explained as an
    offset to more intense competition in the foremarket good.”
    
    Id. at 5-103.
    In that scholarly view, then, Kodak identified a
    pair of possible conditions in which primary market
    competition will not discipline aftermarket prices, but it
    should not be read as embracing any broader economic theory
    of tying liability.
    We have not read Kodak quite so narrowly. The
    Supreme Court emphasized that “[l]egal presumptions that
    rest on formalistic distinctions rather than actual market
    realities are generally disfavored in antitrust law” and that
    Unless one of these conditions is satisfied, the
    defendant without power in the [primary]
    market also lacks the power to charge
    supracompetitive prices for unique [aftermarket
    products].
    Areeda & Hovenkamp, Fundamentals, supra, § 5.12, at 5-102
    to 103.
    In a companion treatise, those scholars suggest going
    even further to limit the reach of Kodak in circumstances of
    competitive primary markets:
    Kodak does not foreclose a rebuttable
    presumption that lack of power in the relevant
    primary market (such as equipment) implies a
    lack of substantial power in derivative markets
    (such as parts or service). Indeed, Kodak may
    even allow a conclusive presumption to this
    effect in order to simplify administration of the
    antitrust laws.
    Phillip E. Areeda & Herbert Hovenkamp, 10 Antitrust Law
    ¶ 1740, at 133 (3d ed. 2011).
    94
    antitrust claims should be resolved “on a case-by-case basis,
    focusing on the particular facts disclosed by the record.”
    
    Kodak, 504 U.S. at 466-67
    (citations and internal quotation
    marks omitted) (quoting Maple Flooring Mfrs. Ass’n v.
    United States, 
    268 U.S. 563
    , 579 (1925)). In Harrison Aire,
    we declined to read Kodak as applying narrowly to only cases
    involving “[a]n aftermarket policy change,” because Kodak
    mandated that courts look at “several relevant factors.”
    Harrison 
    Aire, 423 F.3d at 384
    . The test is more broad: a
    plaintiff pursuing a Kodak-style claim must present evidence
    to support a plausible economic explanation that competition
    in the primary market is “dissociat[ed] ... from conditions in
    the aftermarket.” 
    Id. Showing exploitation
    of locked-in customers, as
    detailed in Kodak, is one way to satisfy that burden, but our
    own case law prevents us from concluding in the abstract that
    it is the only way to do so. Therefore, we interpret Kodak as
    standing for two propositions: (1) that firms operating in a
    competitive primary market are not thereby categorically
    insulated from antitrust liability for their conduct in related
    aftermarkets; and (2) that exploitation of locked-in customers
    is one theory that courts will recognize to justify such
    liability.    Kodak identified factors to evaluate alleged
    anticompetitive aftermarket behavior, and it is possible that
    those factors may support a theory of antitrust liability that is
    not necessarily predicated on lock-in exploitation. But any
    such alternative theory must satisfy the more general rule that
    an antitrust theory needs to “make[] ... economic sense” and
    be supported by the evidence. 
    Matsushita, 475 U.S. at 587
    .
    Having laid out the applicable principles of law for
    Kodak-style tying and monopolization claims, we turn to their
    95
    application in the two surviving antitrust counterclaims in this
    case.49
    2.     PBX Attempted Monopolization
    Claim
    Avaya argues that we should reverse the PBX
    attempted monopolization judgment on two grounds. First, it
    says that, once it introduced contract language in 2008 that
    made clear to customers that they would not be able to use
    ISPs, no Kodak claim could lie as a matter of law. Second, it
    asserts that, as a matter of law, TLI’s evidence of predatory
    conduct is insufficient to support a § 2 attempted
    monopolization claim. We agree that Avaya cannot be liable
    for PBX systems sold after the 2008 contracts were
    introduced, but we cannot conclude that there was insufficient
    evidence to support a verdict of liability for the pre-2008
    period.
    49
    As a reminder, those surviving antitrust
    counterclaims are for attempted monopolization in the PBX
    maintenance services market, in violation of § 2 of the
    Sherman Act; and tying PDS software patches to maintenance
    services, in violation of §1 of the Sherman Act. Given the
    arguments before us, ours is not to reason why the jury found
    those particular counterclaims compelling while rejecting the
    rest.
    “We exercise plenary review” over a district court’s
    decision on whether to grant judgment as a matter of law
    against a jury verdict, but we “must not weigh evidence,
    engage in credibility determinations, or substitute [our]
    version of the facts for the jury’s.” Pitts v. Delaware, 
    646 F.3d 151
    , 155 (3d Cir. 2011).
    96
    a.     Post-2008 Sales Contracts
    According to Avaya, by May 2008, all purchasers of
    new PBX systems were on notice that they were contractually
    barred from using ISPs, so that there could be no antitrust
    aftermarket for maintenance. It points out that the sales
    agreement that accompanied PBX systems at that point
    expressly provided for “[l]icense [r]estrictions” that made it
    clear to purchasers – sophisticated and unsophisticated alike –
    that they could not use ISPs for maintenance. (J.A. 7283.)
    Specifically, § 6.2 of the sales agreement provided that the
    Customer agrees not to ... allow any service
    provider or other third party, with the exception
    of Avaya’s ... resellers and their designated
    employees ... to use or execute any software
    commands that cause the software to perform
    functions that facilitate the maintenance or
    repair of any Product except ... those software
    commands that ... would operate if ... [MSPs]
    were not enabled or activated[.]
    (Id.) Even TLI’s CEO, Douglas Graham, testified that when
    Avaya introduced that version of the sales contract for its new
    PBX systems, it was “making it clear that ... part of buying [a
    PBX] is the customer giving up the ability to access an
    [ISP].” (J.A. 2746.)
    In its post-trial opinion granting TLI’s request for an
    injunction, the District Court endorsed that view, even
    quoting Graham’s language. Accordingly, it limited the
    97
    injunction against Avaya’s restraints on ISPs to cover only
    those PBX systems purchased prior to May 2008.50
    We agree that no antitrust liability for a Kodak-style
    attempted monopolization claim could lie after May 2008
    when customers were put on clear notice that purchasing an
    Avaya PBX precluded use of ISP maintenance. As we
    explained in Queen City Pizza, when the defendant’s power
    “stems not from the market, but from plaintiffs’ contractual
    agreement,” then “no claim will 
    lie.” 124 F.3d at 443
    . By
    May 2008, PBX customers were on clear notice that Avaya
    “retained significant power over their ability to purchase
    cheaper [maintenance] from alternative sources because that
    authority was spelled out in detail in section [6.2] of the
    standard [customer] agreement.” 
    Id. at 440.
    If the customers
    viewed those terms as “overly burdensome ... at the time they
    were proposed, [they] could have purchased a different
    [brand] of [PBX].” 
    Id. at 441.
    Avaya was therefore
    “subjected to competition at the pre-contract stage” in the
    primary market, 
    id. at 440,
    which was undeniably
    competitive. Absent a new and compelling economic theory
    to justify antitrust liability that reaches beyond Kodak –
    50
    TLI seeks to downplay the effect of the post-2008
    customer agreements by arguing that they were “boilerplate”
    and “ambiguous” (Answering Br. at 36), and by arguing that
    there was “no evidence that any post-May 2008 Avaya PBX
    purchasers signed the form contracts” (id. at 38). We
    conclude that there is no reason to disturb the District Court’s
    factual findings or legal conclusion on this point. The
    contractual language is unambiguous, and TLI’s own CEO
    acknowledged the language’s clarity and its use beginning
    with the new PBX systems introduced in 2008.
    98
    which TLI has not provided – Avaya cannot be liable under
    the antitrust laws for enforcing a transparent contract freely
    agreed to in a competitive market.
    “The purpose of the [Sherman] Act is not to protect
    businesses from the working of the market; it is to protect the
    public from the failure of the market.” Spectrum Sports, Inc.
    v. McQuillan, 
    506 U.S. 447
    , 458 (1993). For PBX systems
    sold after May 2008, TLI could not credibly claim that Avaya
    was abusing its market power over locked-in customers.
    Instead, TLI’s complaint was with its potential customers,
    who had agreed to Avaya’s terms forbidding ISP maintenance
    in a competitive market. TLI may wish that the PBX
    customers had demanded access to ISPs when negotiating
    with Avaya, but that is not a complaint cognizable under the
    antitrust laws. Therefore, any PBX systems sold during and
    after May 2008 cannot be a basis for holding Avaya liable for
    attempted monopolization.
    b.     Sufficiency of Evidence of
    Predatory Conduct
    The Supreme Court has established that
    [t]he offense of monopoly under § 2 of the
    Sherman Act has two elements: (1) the
    possession of monopoly power in the relevant
    market and (2) the willful acquisition or
    maintenance of that power as distinguished
    from growth or development as a consequence
    of a superior product, business acumen, or
    historic accident.
    99
    
    Grinnell, 384 U.S. at 570-71
    . The purpose of that two-
    element test for monopolization is to avoid imposing liability
    when a firm has come to possess a dominant market position
    in procompetitive fashion by simply out-competing its rivals
    with a superior product or service. Therefore, even a firm
    with dominant market share will be liable only when its
    actions are predatory or anticompetitive in nature. More
    specifically, a § 2 claim will lie only when “(1) ... the
    defendant has engaged in predatory or anticompetitive
    conduct with (2) a specific intent to monopolize and (3) a
    dangerous probability of achieving monopoly power.”
    Spectrum 
    Sports, 506 U.S. at 456
    . Phrased another way, the
    would-be monopolist must make “use of monopoly power ‘to
    foreclose competition, to gain a competitive advantage, or to
    destroy a competitor.’” 
    Kodak, 504 U.S. at 482-83
    (quoting
    
    Griffith, 334 U.S. at 107
    ).
    Avaya argues that, as a matter of law, there was
    insufficient evidence of predatory conduct to sustain the
    conclusion that the second element of a § 2 claim had been
    proven. According to Avaya, the allegedly predatory acts –
    e.g., terminating dealings with TLI; sending “fear, doubt, and
    uncertainty” letters to TLI’s maintenance customers; and
    trespassing and spying on TLI’s customers – cannot support a
    verdict of antitrust liability. We find some merit to Avaya’s
    arguments that those individual acts may be justifiable and
    not anticompetitive, but we need not resolve this particular
    argument because it misses the forest for the trees.
    It is true that, in a traditional § 2 claim, a plaintiff
    would have to point to specific, egregious conduct that
    evinced a predatory motivation and a specific intent to
    monopolize. See Spectrum 
    Sports, 506 U.S. at 456
    . But in
    100
    the context of a Kodak claim, any proof that the primary
    market and the aftermarket are separate for antitrust purposes
    will necessarily include substantial evidence of predatory
    conduct. The basis of a prototypical Kodak claim is that
    through some combination of price discrimination and post-
    sale surprise in the aftermarket, the defendant has managed to
    dissociate a competitive primary market from an aftermarket
    that the defendant dominates. In Kodak, that domination was
    through control over proprietary parts; here, it is alleged to
    exist through control of proprietary software. If a Kodak
    defendant has managed to create a relevant antitrust
    aftermarket, then, it has necessarily acted to “foreclose
    competition,” 
    Griffith, 334 U.S. at 107
    , or to achieve the
    “willful acquisition ... of monopoly power,” 
    Kodak, 504 U.S. at 483
    . In this case, there is no question that Avaya
    dominates the market for maintenance services on its system,
    or that control over the maintenance market was the express
    intent of its efforts to exclude ISPs. Its every action giving
    rise to this litigation evinces an intent to dominate the
    maintenance market. The central antitrust question, then, is
    whether that market is dissociated from the primary PBX
    market in a way that makes such domination anticompetitive.
    Without itself resolving whether a Kodak claim will
    necessarily include significant evidence of predation, the
    Supreme Court’s analysis in Kodak suggested that our
    approach is the right one. In considering the predation prong
    of § 2 claims, the Court in Kodak merely incorporated its
    prior analysis of market separation to conclude that the
    plaintiffs had “presented evidence that Kodak took
    exclusionary action to maintain its parts monopoly and used
    its control over parts to strengthen its monopoly share of the
    Kodak service market.” 
    Id. If we
    substitute “Avaya” for
    101
    “Kodak” and “ODMCs/MSPs” for “parts,” we can write the
    same sentence in this case. Rather than requiring some proof
    of additional predatory conduct in the maintenance market,
    that portion of the Kodak opinion focused instead on Kodak’s
    affirmative defense that “‘valid business reasons’ [could]
    explain [its] actions.” 
    Id. (quoting Aspen
    Skiing, 472 U.S. at
    605
    ).
    We apply the same analysis here. The evidence that
    convinced the jury that Avaya has dissociated the primary
    market from the aftermarket is sufficient to show
    exclusionary conduct for purposes of § 2. For that reason, we
    reject Avaya’s request for judgment as a matter of law
    because it asks for proof of additional predatory conduct that
    is unnecessary in a case like this.51
    3.     PDS Tying Claim
    Avaya also asks us to reverse the judgment against it
    for unlawfully tying PDS patches to maintenance, arguing
    that there was insufficient evidence to support any finding
    that there was a distinct aftermarket for patches. Before
    51
    Our reading of Kodak further bolsters our conclusion
    that the District Court’s judgment as a matter of law on
    Avaya’s common law claims necessarily prejudiced the
    antitrust verdict. Protecting itself from tortious forms of
    competition may well have been a valid business reason to
    engage in defensive exclusionary conduct, and that kind of
    affirmative defense was the crux of the Kodak opinion’s § 2
    analysis. That Avaya was not able to make such an argument
    to the jury improperly hindered its defense against TLI’s § 2
    claims.
    102
    October 2007, Avaya argues, it “made patches freely
    available to all Avaya PDS owners without requiring them to
    purchase Avaya maintenance.” (Opening Br. at 75.) The
    patches were available on Avaya’s website for any PDS
    owner to access, irrespective of who provided system
    maintenance. At trial, TLI’s CEO agreed with that, and a
    representative of SunTrust – the one customer that TLI put on
    as evidence for its PDS tying claim – testified that TLI was
    able to provide patches during the entire period that SunTrust
    hired TLI for maintenance. For PDS hardware sold from
    October 2007 onward, Avaya did restrict access to its PDS
    patches to users of Avaya’s own support services, but the
    requirement to purchase Avaya support with the PDS
    hardware was made clear at the time of sale. Indeed, the
    SunTrust representative testified that when the firm purchased
    a new Avaya PDS after October 2007, it was informed that it
    would be required to purchase Avaya support and, if it wished
    to receive patches, could not use an ISP.
    TLI does not challenge those basic facts, but it argues
    that the PDS verdict can nonetheless stand. As to the pre-
    2007 period, it argues that “Avaya used the threat of
    withholding patches to coerce PDS owners into purchasing
    maintenance from Avaya” (Answering Br. at 64), so that,
    even though the patches were formally available for free,
    Avaya still effected a tie. TLI points, as an example, to a
    letter sent in 2005 to PDS customers telling them that they
    risked losing access to a host of services, including patches, if
    they “ch[o]se to engage an Unauthorized Service Provider for
    services,” and threatening that “Avaya will take all necessary
    legal action against violators in order to protect Avaya
    proprietary intellectual property.” (J.A. 6945.) As to the
    post-2007 period, TLI argues that “Avaya PDS owners were
    103
    not made aware of ... Avaya’s policies.” (Answering Br. at
    67.) Moreover, even if the policy was transparent, TLI argues
    that there was nonetheless sufficient evidence that the
    “patches aftermarket ... was not disciplined by the primary
    PDS market.” (Id. at 66.)
    The 2005 letter to PDS customers, like the PBX FUD
    letters, was no doubt a frustration to TLI in its own efforts to
    build its business. Avaya was indeed intent on dominating its
    own intra-brand market. But that does not mean that Avaya
    fell afoul of the antitrust laws, which “were enacted for ‘the
    protection of competition not competitors.’” Brunswick
    Corp. v. Pueblo Bowl-O-Mat, Inc., 
    429 U.S. 477
    , 488 (1977)
    (quoting Brown Shoe Co. v. United States, 
    370 U.S. 294
    , 320
    (1962)). It is undisputed that Avaya’s patches were freely
    available to customers on its website without any strings
    attached before 2007, and the only witness put forward by
    TLI to prove the efficaciousness of Avaya’s threats
    acknowledged that his firm was freely able to receive patches
    through TLI. “[W]here the buyer is free to take either
    product by itself there is no tying problem even though the
    seller may also offer the two items as a unit at a single price.”
    Northern 
    Pacific, 356 U.S. at 6
    n.4. Given that Avaya
    offered the patches freely to PDS customers, TLI needed to
    put forward compelling evidence that Avaya was somehow
    nevertheless effecting a de facto tie between patches and
    maintenance. Were TLI to prevail on vague allegations that a
    strongly-worded letter was as effective as a technological or
    contractual tie, that would dramatically expand the reach of
    tying liability. The Kodak standard demands more, and we
    accordingly agree that the evidence before the jury was
    insufficient as a matter of law to sustain a tying claim
    104
    pertaining to PDS systems sold before October 2007, while
    patches were still freely available.
    As for PDS systems sold after Avaya’s October 2007
    policy went into effect, TLI’s tying claim runs into the same
    problems as did its claim for antitrust injury in the post-2008
    PBX market – Avaya introduced clear contractual language in
    the primary market prohibiting ISP use. If new PDS
    customers considered the requirements to purchase Avaya
    software support and to refrain from using ISPs “overly
    burdensome ... at the time they were proposed, [the buyers]
    could have purchased a different [brand] of [PDS].” Queen
    City 
    Pizza, 124 F.3d at 441
    . Where the primary market is
    indisputably competitive – and there is no dispute here that it
    was and is – a plaintiff must show special circumstances, such
    as Kodak-style lock-in, to overcome the inference that such
    competition will discipline any related intra-brand
    aftermarkets. Given that post-2007 PDS customers were
    required to purchase an Avaya service plan with their PDS,
    the link of PDS and maintenance service was fully transparent
    in the primary market. That undermines any argument for
    Kodak-style lock-in or aftermarket surprise that TLI could
    make. Having no alternative theory, its PDS tying claim also
    fails as a matter of law for the post-October 2007 period.
    We therefore reverse the jury’s entire PDS tying
    verdict and remand with instructions for the District Court to
    enter judgment for Avaya on that claim. Given that result, we
    pause briefly to note that our reversal of the PDS verdict
    would endanger the validity of the damages award, even if we
    were not otherwise vacating it because of the District Court’s
    errors regarding the common law claims. “Where a jury has
    returned a general verdict and one theory of liability is not
    105
    sustained by the evidence or legally sound, the verdict cannot
    stand because the court cannot determine whether the jury
    based its verdict on an improper ground.” Wilburn v.
    Maritrans GP Inc., 
    139 F.3d 350
    , 361 (3d Cir. 1998)
    (citations omitted); see also Avins v. White, 
    627 F.2d 637
    , 646
    (3d Cir. 1980) (Where “[i]t is ... impossible to determine if
    the jury based its verdict on all” the allegedly unlawful acts
    “or ... on only one,” then “there is the distinct possibility that
    if we affirm the jury’s verdict, we may do so on the basis of”
    lawful acts.); Albergo v. Reading Co., 
    372 F.2d 83
    , 86 (3d
    Cir. 1966) (“Where, as here, a general verdict may rest on
    either of two claims – one supported by the evidence and the
    other not – a judgment thereon must be reversed.”).
    In this case, the verdict form merely asked the jury to
    name “the total amount of damages, if any, that ... TLI[] has
    proven ... were caused by Avaya’s violation(s) of the antitrust
    laws.” (J.A. 640.) There is therefore no way to discern
    which portion of the damages the jury attributed to the PDS
    tying claim, and which to the PBX attempted monopolization
    claim. It is true that the PBX market is substantially larger,
    but if we affirmed the damages verdict on the basis of the pre-
    2008 PBX claim alone, we would nonetheless risk the
    “distinct possibility that ... we may do so on the basis of”
    damages attributable to a liability theory that is invalid.
    
    Avins, 627 F.3d at 646
    . Moreover, the jury lacked a cogent
    way to disaggregate the PBX and PDS damages in the first
    place because TLI’s expert offered testimony based on
    combined damages.52 We therefore have no way to know
    52
    Moreover, the damages expert’s two models
    projected damages of between $133 million and $147 million,
    a far cry from the jury’s finding of $20 million in damages.
    106
    what portion of the damages verdict is attributable to the
    invalid PDS tying liability theory, which independently
    requires vacatur of the damages award.53
    In trying to figure out what portion of that award was
    attributable to which systems, we would have a hard time
    reasoning how the jury came to its number in the first place,
    much less how much is attributable to a liability theory that
    survives this appeal.
    53
    The parties also fight over the jury instructions, but
    those are arguments we need not resolve because we are
    vacating the verdict on other grounds. Some comment is
    nevertheless in order. Avaya complains that the District
    Court simply gave the jury a list of factors to consider in an
    “uncabined” manner to determine whether the primary market
    was dissociated from the maintenance aftermarket. (Opening
    Br. at 52.) Although there is some merit to that complaint,
    there is also much to applaud in the District Court’s efforts to
    distill and describe this complex area of law for the jury. In
    particular, we appreciate that the Court properly identified
    from Kodak and our precedents relevant factors for the jury’s
    consideration.
    We agree, however, that – if there is a retrial – the
    Court should consider describing to the jury a logical path for
    it to follow in evaluating whether the primary market is
    dissociated from the aftermarket. For example, with respect
    to the PBX attempted monopolization claim, a theory of
    dissociation by aftermarket surprise in this case might run as
    follows:
    1. If you find that customers could not have predicted
    that Avaya would condition their use of MSPs and
    ODMCs on customers’ refusal to use ISPs, you may
    107
    conclude that Avaya enacted a surprise aftermarket
    policy change.
    2. If you determine that Avaya enacted such an
    aftermarket policy change, you must then evaluate
    whether Avaya had the ability to exercise market
    power in the aftermarket. To reach such a conclusion,
    you must conclude that Avaya and its Business
    Partners were able to exclude competitors in the
    aftermarket, and that switching costs in the primary
    market locked in customers.
    3. If you determine that Avaya enacted a surprise
    aftermarket policy change and that it had market
    power in the aftermarket, you may then decide whether
    it was possible for Avaya to use that market power to
    exploit customers.      To find the possibility of
    exploitation, you must conclude that Avaya had the
    ability to charge supracompetitive prices in the
    aftermarket.
    4. If, and only if, you reach all three of the prior
    conclusions, may you find that the PBX maintenance
    market was a relevant antitrust aftermarket.
    The foregoing example is not meant as a directive that the
    District Court must follow, but rather as one proposed
    approach to “channel” – as Avaya puts it – the jury’s
    consideration of the factors identified in Kodak. (Opening Br.
    at 53.)
    Avaya also appealed the District Court’s decision to
    grant TLI prejudgment interest on the basis of what it
    determined to be Avaya’s vexatious litigation strategy.
    Because we vacate the verdict and the corresponding
    damages award, the issue of prejudgment interest is moot, and
    108
    IV.    TLI’s Cross-Appeals
    Having resolved Avaya’s appeals, we turn now to
    TLI’s cross-appeals. It challenges the District Court’s grant
    of summary judgment against two of its tort counterclaims
    and against one of its antitrust counterclaims. It also
    challenges the District Court’s decision under the Noerr-
    Pennington doctrine that TLI could not use Avaya’s litigation
    conduct as evidence of anticompetitive behavior. All of those
    rulings are sound, and TLI’s arguments are not.54
    A.     Summary Judgment on TLI’s Common Law
    Claims
    We begin with the District Court’s grant of summary
    judgment against TLI’s counterclaims for trade libel and for
    tortious interference with prospective economic advantage.
    Both claims were based on the so-called FUD letters that
    Avaya sent to existing and prospective TLI customers. The
    tortious interference claim was also based on Avaya’s
    we decline to address it. The question may be considered
    afresh, if necessary, following retrial.
    54
    Our review of a district court’s grant of summary
    judgment is plenary. Boyle v. Cty. of Allegheny Pa., 
    139 F.3d 386
    , 393 (3d Cir. 1998). “[S]ummary judgment may be
    granted if the movant shows that there exists no genuine issue
    of material fact that would permit a reasonable jury to find for
    the nonmoving party. All facts and inferences are construed
    in the light most favorable to the non[]moving party.”

    deactivation of TLI customers’ MSPs. The District Court
    granted summary judgment against TLI on those claims on
    the ground that TLI did not present sufficient evidence to
    create a dispute of material fact over whether Avaya’s
    conduct actually caused TLI any loss in business.55
    55
    The parties dispute whether the District Court
    applied the correct legal standards for the tort claims. For
    tortious interference, “New Jersey law requires that a plaintiff
    ... present proof that but for the acts of the defendant, the
    plaintiff would have received the anticipated economic
    benefits.” Lightning 
    Lube, 4 F.3d at 1168
    (internal quotation
    marks omitted). TLI disputes whether the District Court
    actually applied that “but for” test, suggesting that it
    improperly demanded that TLI prove that Avaya’s actions
    were the sole cause of injury. Despite some potentially
    confusing language, the District Court’s opinion did apply the
    “but for” test as explicated in Lightning Lube. TLI also
    argues that the District Court should have instead applied a
    test evaluating whether Avaya’s conduct was a “substantial
    factor” in causing TLI’s injury. See Verdicchio v. Ricca, 
    843 A.2d 1042
    , 1056 (N.J. 2004) (applying the “substantial
    factor” test in a medical malpractice case). Because a
    “substantial factor” causation test would not have altered the
    result, we need not consider whether it was more appropriate.
    With regard to the legal standard for trade libel, both
    parties agree that TLI had to prove special damages. TLI
    wanted the Court to apply a “material and substantial part”
    test for causation of those damage, see Patel v. Soriano, 
    848 A.2d 803
    , 835 (N.J. Super. Ct. App. Div. 2004), whereas
    Avaya supports the “natural and direct result” standard that
    the District Court did apply, see Mayflower Transit, LLC v.
    Prince, 
    314 F. Supp. 2d 362
    , 378 (D.N.J. 2004). Again, we
    110
    The District Court provided a detailed explanation of
    the deficiency of the evidence before it. As to the MSP
    deactivations, the Court observed that MSP access was not
    required to provide maintenance, citing TLI’s own
    interrogatory responses about alternative methods that it in
    fact used to provide service to customers. As the Court
    explained, TLI “used ... default passwords or hired a third
    party to determine active passwords,” so that “whether MSPs
    were activated had little bearing on whether [TLI] could
    provide maintenance to customers.” (J.A. 105.)56 Those
    alternative methods were sufficiently successful, in fact, that
    they led Avaya to bring suit against TLI, alleging that they
    were unlawful and resulted in the loss to Avaya of significant
    business.
    As to the FUD letters, the District Court decided that
    TLI had not “come forth with sufficient evidence that the
    Avaya letters were the de facto cause of the loss of current
    and prospective maintenance contracts.” (J.A. 105.) TLI’s
    examples of lost contracts were not at all persuasive. For
    instance, TLI suggested that the State of Michigan was one
    such lost contract, but an employee of that state testified that
    there were “numerous reasons” not to use TLI – unrelated to
    need not resolve which standard is correct because the
    outcome is the same under either.
    56
    At trial, Scott Graham validated the District Court’s
    conclusion when he testified that he was “[n]ot ... aware of” a
    case in which TLI was not able to get “into the maintenance
    software” of a prospective customer. (J.A. 2443.) In fact, it
    is “[c]orrect” that TLI was “always successful.” (Id.)
    111
    Avaya, and some directly caused by TLI – and that she was
    not under any “impression that Avaya would sue the State of
    Michigan if it awarded the contract to [TLI].” (J.A. 106.)57
    The only specific example TLI provided of a customer who
    declined its services because of a FUD letter was
    substantiated only by an email – inadmissible as hearsay –
    sent by a TLI employee complaining about the lost contract.
    Finally, the Court refused to draw any inferences from the
    report of TLI’s damages expert on the grounds that it was
    “not supported ... by affidavits or any other evidence that
    would be admissible at trial.” (J.A. 108.)
    In this appeal, TLI relies principally upon that expert
    report and contests the District Court’s characterization of it,
    arguing vaguely that the report was based on “business
    records [and] excerpts from depositions of customers and
    TLI[] employees.” (Answering Br. at 93.) In support of that
    contention, TLI cites the expert’s certification, in which he
    declared that he “relied upon facts, data and work typically
    relied upon by experts in the economic/accounting industry.”
    (Suppl. App. 10.) TLI also cites 93 pages of inscrutable
    spreadsheets in which the expert – without explanation –
    assigned various damages to contracts that TLI allegedly lost
    due to Avaya’s conduct.
    57
    Other examples provided by TLI were similarly
    unimpressive. For instance, TLI relied on a cease and desist
    letter that it sent to Avaya in 2010. The District Court
    concluded that the mere existence of such a letter “is no more
    helpful to the Court on summary judgment than ... pleadings,”
    without additional “evidence sufficient to prove that the
    allegations made in the ... letter are in fact true.” (J.A. 107.)
    112
    The District Court’s rejection of TLI’s argument was
    thoroughly justified. The evidence TLI offered in opposing
    summary judgment consisted of naked accusations that
    Avaya’s conduct cost it business. That the allegations were
    recited by an expert witness or by TLI employees does not
    bolster them.58 See Advo, Inc. v. Phila. Newspapers, Inc., 
    51 F.3d 1191
    , 1198 (3d Cir. 1995) (“[E]xpert testimony without
    ... a factual foundation cannot defeat a motion for summary
    judgment.”). Even now on appeal, after a decade of
    litigation, TLI cannot point to one specific example where it
    has credible evidence that Avaya’s allegedly tortious conduct
    harmed its business. We therefore agree with the District
    Court that TLI failed to present sufficient evidence to create a
    material dispute of fact about whether Avaya’s MSP
    deactivations or FUD letters caused injury to TLI. Summary
    judgment was appropriate on both the tortious interference
    and the trade libel claims.
    B.     Summary Judgment on PBX Upgrade Tying
    Claim
    The jury rejected TLI’s § 1 tying claim for the PBX
    market and found that there was no relevant antitrust
    aftermarket for PBX patches, but TLI nonetheless asks us to
    revive a separate § 1 tying claim. It appeals the District
    58
    The expert’s credibility is further undermined by the
    fact that at a subsequent Daubert hearing, the District Court
    determined that he was “‘[c]learly ... not competent’ to testify
    about an individual customer’s motivations.” (Third Step Br.
    at 62 (alteration and omission in original) (quoting J.A.
    4071).)
    113
    Court’s grant of summary judgment against its claim that
    Avaya unlawfully tied PBX upgrades and maintenance.
    Before addressing the reasoning of the District Court,
    we note that, in light of our already-set-forth explanation of
    Kodak-style tying claims, we are skeptical of the tying claim
    regarding PBX upgrades, especially given the jury’s rejection
    of the tying claim related to PBX software patches.
    Upgrading a PBX system requires a customer to step back
    into the competitive primary PBX market, thereby at least
    partially ameliorating any lock-in concern and making it less
    likely that Avaya could dissociate the primary market from an
    aftermarket. We acknowledge that in the PBX upgrade
    market there may still be some reliance on past investments in
    an old Avaya system, but if the jury rejected the notion that
    PBX patches satisfied the Kodak theory – when patches are
    strictly aftermarket products – we doubt that it would have
    been more sympathetic to an argument that upgrades were
    unlawfully used as a tie.
    Antitrust theory aside, the District Court granted
    summary judgment for the simple reason that TLI had failed
    to present any substantial evidence that Avaya’s alleged
    threats to withhold upgrades had actually affected “a
    substantial amount of interstate commerce,” as required to
    make out a § 1 claim. (J.A. 165.) It characterized TLI’s
    proffered evidence as consisting of “little more than
    assertions,” which the “Court [found] insufficient.” (Id.)
    That evidence – which TLI presses upon us anew on appeal –
    again consists of expert reports arguing that Avaya used
    upgrades as part of a scheme to foreclose competition in the
    maintenance market. Avaya defends the District Court by
    114
    arguing that that “evidence” was merely unsupported
    assertions filtered through TLI’s experts.
    Reviewing the record ourselves, and drawing all
    reasonable inferences in favor of TLI, we find ourselves in
    agreement with Avaya and the District Court. In opposing
    summary judgment, TLI presented no evidence to raise an
    issue of material fact about whether Avaya was able to harm
    TLI by using PBX upgrades to restrain competition in the
    maintenance market. We will therefore also affirm that aspect
    of the District Court’s summary judgment order. 59
    C.      Noerr-Pennington Ruling
    The final issue we consider is TLI’s cross-appeal of
    the District Court’s ruling, under the Noerr-Pennington
    doctrine, that TLI could not present evidence at trial of
    Avaya’s litigation conduct as a basis for the accusation of
    monopolistic conduct. “Under the Noerr-Pennington doctrine
    – established by Eastern Railroad Presidents Conference v.
    Noerr Motor Freight, Inc., 
    365 U.S. 127
    (1961), and United
    Mine Workers v. Pennington, 
    381 U.S. 657
    (1965) –
    defendants are immune from antitrust liability for engaging in
    conduct (including litigation) aimed at influencing
    59
    We note, however, that insofar as TLI may have
    later developed more evidence on the use of upgrades to tie,
    that evidence remains relevant to TLI’s attempted
    monopolization claim. There is nothing to prevent TLI from
    presenting the upgrade tying theory to the jury as part of its
    surviving § 2 claim on remand, but that does not ameliorate
    the fact that its evidence at the summary judgment stage was
    so scant.

    decisionmaking by the government.” Octane Fitness, LLC v.
    ICON Health & Fitness, Inc., 
    134 S. Ct. 1749
    , 1757 (2014)
    (citation omitted). In Professional Real Estate Investors, Inc.
    v. Columbia Pictures Industries, Inc., 
    508 U.S. 49
    (1993), the
    Supreme Court explained that “sham” litigation – unlike
    ordinary litigation – is not off limits as a source of antitrust
    liability. The Court gave a two-part test for identifying a
    lawsuit as a sham: “First, the lawsuit must be objectively
    baseless in the sense that no reasonable litigant could
    realistically expect success on the merits. ... [S]econd[,] ...
    the baseless lawsuit conceals ‘an attempt to interfere directly
    with the business relationships of a competitor,’” 
    id. at 60-61
    (emphasis removed) (quoting 
    Noerr, 365 U.S. at 144
    ),
    “through the ‘use of the governmental process – as opposed
    to the outcome of that process – as an anticompetitive
    weapon,’” 
    id. at 61
    (alteration and emphases removed)
    (quoting City of Columbia v. Omni Outdoor Advert., Inc., 
    499 U.S. 365
    , 380 (1991)).
    TLI challenges the District Court’s contention that “the
    whole case has to be a sham” for the sham exception to apply.
    (Suppl. App. 190.) Instead, TLI argues, the sham exception
    should be applied on a claim-by-claim basis. Avaya responds
    by citing the language in Professional Real Estate that refers
    to a “lawsuit” rather than a claim, and which references the
    “governmental process” rather than any specific action in a
    suit. It also argues that, as a policy matter, adopting a claim-
    by-claim “approach would introduce extraordinary
    complexity into jury deliberations” by forcing juries to not
    only decide the merits of each claim but also decide which are
    objectively reasonable or not. (Third Step Br. at 66.) As the
    District Court noted when ruling on the issue, cases often
    involve claims of varying degrees of merit, many of which
    116
    are weeded out pre-trial, and it would be impractical to run a
    litigation system that made those kinds of claims subject to
    antitrust suits.
    We agree with that conclusion. True, one might
    imagine a situation where a single claim, separated from an
    otherwise arguably meritorious suit, is so harmful and costly
    to a defendant that it might impose anticompetitive harm on
    the defendant in a way that triggers the sham litigation
    exception to Noerr-Pennington. But the Supreme Court’s
    elaboration of the “sham” exception suggests that we should
    not go hunting for that example, and this case is not it. Some
    of Avaya’s claims that were dismissed before trial may have
    been weak, but they were part and parcel of a course of
    litigation that proceeded to two months of substantial
    evidence and argument to a jury. We do not consider
    Avaya’s affirmative claims to be frivolous or unsubstantiated;
    in fact, we are vacating the Rule 50 judgment that was
    entered against them. TLI may consider Avaya’s litigation
    conduct vexatious – as the District Court did in awarding
    prejudgment interest – but its suit against TLI was not a
    “sham.”60 We therefore affirm the District Court’s ruling that
    Avaya’s litigation conduct was protected from antitrust
    liability by the Noerr-Pennington doctrine.
    60
    Which is not to say that we endorse the District
    Court’s determination that the award of prejudgment interest
    was appropriate in this case. Again, Avaya’s present
    challenge to that award has been mooted by our disposition
    with respect to the other claims presented.
    117
    V.    Conclusion
    For the foregoing reasons, we will vacate the judgment
    of the District Court and remand for further proceedings
    consistent with this opinion. We will also reverse the
    judgment of liability on the entire PDS tying claim and on the
    PBX attempted monopolization claim as to the post-2008
    time period and will remand with instructions to enter
    judgment as a matter of law for Avaya on those claims. We
    will affirm the orders of the District Court as to all issues
    raised by TLI’s cross-appeal.

    Avaya, Inc. v. Telecom Labs, Inc.; TeamTLI.com Corp.;
    Continuant, Inc.; Scott Graham; Douglas Graham; Bruce
    Shelby, Nos. 14-4174, 14-4277
    HARDIMAN, Circuit Judge, concurring in part and
    dissenting in part.
    For litigation that has lasted some fifteen years, this
    appeal involves remarkably few disputed facts. The trouble
    began soon after Plaintiff Avaya (the Goliath of this saga)
    laid off many of its workers because of a downturn in the
    telecommunications market in 2000. Those layoffs gave rise
    to independent companies that offered aftermarket
    maintenance on the Private Branch Exchanges (PBXs) sold
    by Avaya. In fact, Avaya provided training and subsidies to
    companies that hired its former employees, and some
    companies became authorized Avaya dealers or business
    partners. Defendant TLI (the David of the saga) became one
    of those official business partners.
    TLI obtained its first customer in 2001 and invested
    millions in its maintenance business. For whatever reason,
    Avaya reversed course in 2002 and began limiting the ability
    of its business partners, customers, and independent
    (unauthorized) providers to perform PBX maintenance. This
    change in strategy resulted in the creation of the Avaya One
    contract, which required Avaya business partners to promise
    not to solicit maintenance business from selected Avaya
    customers. Some 300 Avaya One contracts were signed and
    TLI signed its contract on March 21, 2003. Unlike all of
    Avaya’s other business partners, however, TLI negotiated a
    handwritten modification to its covenant not to compete that
    expressly authorized TLI to solicit maintenance business from
    certain Avaya customers. This modification was the spark
    1
    that ignited the forest fire that continues to rage twelve years
    later.
    When Avaya’s Head of Global Sales, Linda
    Schumacher, learned of the carve-out TLI had negotiated, she
    was “shocked” and quickly took steps to cancel TLI’s
    contract just four months after it was signed. On July 31,
    2003, Avaya gave the required 60 days’ notice that it was
    terminating the contract and spent the months of August and
    September notifying TLI’s customers that it soon would no
    longer be an Avaya business partner. Claiming antitrust
    violations, TLI went to federal court seeking an injunction
    requiring Avaya to allow TLI access to the codes necessary to
    maintain its customers’ machines. The court denied the
    injunction and TLI dropped the case.
    Undeterred, TLI used a variety of methods to access its
    customers’ PBXs in order to perform maintenance. TLI
    accessed some machines by using passwords and logins it had
    received previously and it obtained others from the internet.
    Some of TLI’s customers had purchased permissions for the
    life of their machines, which enabled TLI to provide
    maintenance by using those logins. Other methods used by
    TLI were deceitful and/or unethical. For example, some
    Avaya business partners acted as conduits for TLI by posing
    as the maintenance provider, only to pass along the
    credentials to TLI. TLI also employed two former Avaya
    employees, David Creswick and Harold Hall, who used what
    they had learned to “hack and crack” the PBXs of TLI’s
    customers to obtain the credentials necessary to service them.
    In short, even after TLI was terminated as an Avaya business
    partner, TLI used various methods to provide aftermarket
    maintenance—a service that purchasers of Avaya’s PBXs
    2
    were expressly authorized by contract to provide for
    themselves or to hire third parties like TLI to provide.
    Avaya sued TLI in federal court in 2006, alleging
    numerous causes of action under federal and state law. After
    seven years of scorched-earth litigation, Avaya withdrew six
    claims just days before the trial began. For almost two
    months, Avaya put on evidence in support of its seven
    remaining claims. At the conclusion of Avaya’s case-in-chief,
    TLI moved for judgment as a matter of law under Rule 50 of
    the Federal Rules of Civil Procedure. The District Court
    granted TLI’s motions, throwing out Avaya’s case in its
    entirety.
    My colleagues on the panel, both experienced former
    trial lawyers and trial judges, conclude that the District Court
    committed legal error when it granted TLI’s Rule 50 motions.
    Although I had far less experience as a trial lawyer and trial
    judge than my distinguished colleagues, my visceral reaction
    to the Court’s Rule 50 decision is consistent with theirs. The
    question looms large: Why, after seven years of discovery
    and two months of trial, did a jurist with 22 years of
    experience not allow any of Avaya’s claims go to the jury?
    To ask the question implies the imprudence of the decision, at
    least on an instinctual level. But visceral reactions aren’t
    always correct, and I must say that after reading the entire
    transcript of the trial, I agree with Judge Irenas’s 52-page
    opinion explaining his reasons for throwing out Avaya’s case.
    After seven years, Avaya finally withdrew almost all of its
    federal claims. The seven state-law claims that remained—
    which involved breach of contract, fraud, and unfair
    competition—simply were not proven at trial. At the end of
    the day, my assessment of Avaya’s case-in-chief is the same
    3
    as the District Court’s: full of sturm und drang, but
    insubstantial.
    Having expressed my opinion on that score, I confess
    enough doubt about the propriety of the District Court’s
    decision to grant the Rule 50 motion that the focus of my
    partial dissent presumes the correctness of my colleagues’
    opinion on that point. Instead, I take issue with the decision to
    vacate the judgment TLI earned on two of its counterclaims
    arising under the antitrust laws. Even assuming, arguendo,
    that the District Court erred when it granted TLI’s Rule 50
    motions, I remain convinced that any error had little or no
    impact on the verdicts in favor of TLI. In my estimation,
    David struck Goliath right between the eyes and should not
    be deprived of his hard-earned victory on the counterclaims.
    The crux of my partial dissent is that I cannot agree
    that the District Court’s rejection of Avaya’s claims “taint[ed]
    the entire trial and the ultimate verdict.” Majority Op. 6.
    Perhaps I would find greater assurance in the Majority’s taint
    analysis if Avaya had adequately raised it. I have serious
    doubts that it did. Even still—without the benefit of
    developed adversarial briefing on the issue—I do not believe
    the District Court’s judgment as a matter of law so impaired
    Avaya’s ability to defend itself against TLI’s allegations of
    anticompetitive conduct that we cannot have confidence in
    the jury verdict as a whole. For that reason, I would affirm the
    verdict with respect to Avaya’s pre-2008 attempted
    monopolization of the PBX maintenance aftermarket and I
    4
    respectfully dissent from the Majority’s holding to the
    contrary.1
    1
    Although I believe the jury was properly instructed as
    to the factors for finding a relevant antitrust aftermarket for
    Avaya PBX system maintenance and could have reasonably
    found Avaya liable for attempted monopolization of that
    aftermarket prior to its introduction of transparent sales
    contracts in May 2008, I agree with the Majority that Avaya
    cannot be held liable for PBX systems sold after that time. I
    also agree that the jury could not have reasonably found
    Avaya liable for tying PDS patches to maintenance either
    before 2007 (the patches were free, so there was no coercion)
    or after (the conditions were clear upfront, so there was no
    relevant antitrust aftermarket). Moreover, because the general
    verdict did not dissociate damages stemming from attempted
    monopolization of the PBX maintenance aftermarket from
    those attributable to the alleged PDS tying, I agree that the
    damages award must be vacated and that we therefore need
    not reach the issue whether the District Court abused its
    discretion in granting TLI’s motion for prejudgment interest
    under the Clayton Act. I also join the Majority’s rejection of
    TLI’s cross-appeals.
    Finally, I commend Judge Jordan for his rigorous
    synthesis of the Eastman Kodak Company v. Image Technical
    Services Inc. branch of antitrust law, which has bedeviled
    litigants and courts alike. I agree with his analysis
    wholeheartedly. Because the District Court’s jury instructions
    comport with the principles outlined by Judge Jordan, I would
    hold that they were sufficient to “properly apprise[] the jury
    of the issues and the applicable law.” Smith v. Borough of
    Wilkinsburg,

    “Forfeiture” and “waiver” are often treated as
    interchangeable terms. As I have explained elsewhere, they
    are not. See Tri-M Grp., LLC v. Sharp,

    they develop it sufficiently to aid our review.” NLRB v.

    in original) (quoting Frank v. Colt Indus., Inc.,

    , 100 (3d Cir. 1990)). This appeal presents just such a
    situation.
    Avaya’s opening brief mentioned the taint issue only
    in passing. The matter received no mention in Avaya’s issues
    section of the brief, which I find significant because the
    question of whether the District Court erred in granting
    judgment as a matter of law against Avaya’s common law
    claims is an issue distinct from whether such error tainted the
    verdict on TLI’s antitrust claims—something the structure of
    the Majority opinion rightly makes clear. See United States v.
    Joseph, 
    730 F.3d 336
    , 341–42 (3d Cir. 2013) (distinguishing
    between “issues” and “arguments”). Then, on the three
    occasions Avaya did mention tainting in its brief, its
    waiver is the intentional relinquishment or abandonment of a
    known right.”) (quoting United States v. Olano,

    argumentation was skeletal at best.4 This was not lost on TLI,
    which—in Avaya’s words—“crie[d] waiver” in its response
    brief. Avaya Reply Br. 18 n.4 (citing TLI Br. 87). Rightly so.
    As TLI put it, Avaya failed to “advance [its] conclusory

    Two of these instances were little more than ipse
    dixits. See Avaya Br. 4 (“The erroneous dismissal of Avaya’s
    claims and the court’s instruction that TLI[’s] conduct was

    id. at 72
    (“In any event, the
    erroneous instructions that tainted the jury’s consideration of
    TLI[’s] “FUD” allegations require a new trial.”). Neither of
    these assertions was supported by any reasoning or citation to
    legal authority or record evidence. The third mention of
    tainting offered a few sentences of additional bluster—
    accusing the trial judge of “discredit[ing] Avaya in the jury’s
    eyes” and “crippl[ing] Avaya’s ability to respond to TLI[’s]
    antitrust claims by showing that it had legitimate and
    procompetitive business reasons” for its actions—but was
    purely skeletal. 
    Id. at 43
    (introductory paragraph to antitrust
    argument section). Avaya again offered no development of its
    theory or citation to case law or the trial record. Passing
    references like these should be deemed forfeited. See Bryant
    v. Gates,

    ‘taint’ contention in a freestanding and developed argument.”
    TLI Br. 86. Because Avaya merely floated the taint idea
    “without squarely arguing it,” FedEx Freight, 
    2016 WL 4191498
    , at *11 (Jordan, J., concurring), I would deem it
    forfeited.
    The three-point tainting theory on which the Majority
    bases its decision comes not from Avaya’s opening brief but
    from its reply brief. See Avaya Reply Br. 18–19; Majority
    Op. 67–79. But the black-letter rule is that “[w]e will not
    revive a forfeited argument simply because” an appellant
    finally develops “it in its reply brief.” Republic of Argentina
    v. NML Capital, Ltd., 
    134 S. Ct. 2250
    , 2255 n.2 (2014); see
    also In re Surrick, 
    338 F.3d 224
    , 237 (3d Cir. 2003). This
    dooms at least two taint-related arguments developed only on
    reply: (1) that judgment as a matter of law against Avaya’s
    common law claims undermined Avaya’s ability to present
    pro-competitive justifications for its conduct, and (2) the
    related point that the District Court erroneously limited
    witness testimony to that effect.
    Avaya did not couch its argument regarding the effects
    of the District Court’s instructions about the lawfulness of
    TLI’s access to maintenance commands on the jury’s
    consideration of the “fear, uncertainty, and doubt” (FUD)
    letters in terms of tainting until its reply brief. It did, however,
    raise this alleged instructional error in its separate argument
    that the jury could not have properly found that Avaya
    engaged in anticompetitive conduct in the PBX maintenance
    aftermarket. I address this argument below. As for the other
    grounds on which the Majority deems the antitrust verdict
    improper, I would hold them forfeited.
    II
    9
    Even had Avaya adequately developed all three prongs
    of its taint argument, I would not conclude that the District
    Court’s errors constituted reversible error. First, the Majority
    concludes that the District Court’s instructions after its
    dismissal of Avaya’s common law claims undermined the
    jury’s ability to assess the reasonableness of Avaya’s actions
    in light of TLI’s allegedly unlawful conduct. It highlights the
    trial judge’s instruction that TLI’s “use of and access to
    [Avaya’s] maintenance software may not be considered by
    you as unlawful when deciding TLI[’s] claims against Avaya
    asserted in the counterclaim.” App. 4739.
    Despite this instruction, Avaya had ample opportunity
    to present the jury with legitimate and procompetitive
    defenses for its actions, and those defenses did not depend on
    whether TLI’s conduct was so egregious as to be against the
    law. Indeed, Avaya’s persistent refrain to the jury was that the
    actions Avaya took against TLI were reasonable because TLI
    was an “unauthorized” PBX servicer undermining Avaya’s
    “procompetitive” Business Partners program. App. 4569–71.5
    5
    In its closing argument, after explaining to the jury
    that it would be instructed that “TLI’s use of and access to
    Avaya’s maintenance software may not be considered by you
    to have been unlawful” Avaya explained that “what remains
    is a series of decisions by you, as to whether Avaya’s conduct
    was a reasonable competitive reaction to the events Avaya
    confronted in the marketplace.” Trial Transcript (“Tr.”)
    3/19/14, 15752. It then proceeded to make the case that
    Avaya’s actions were nothing more than “legitimate efforts to
    protect its software and its business model,” 
    id. at 15756;
    that
    the law “allows for fierce, fierce competition,” 
    id. at 15757;
    that Avaya’s practices were consistent with industry practices
    10
    Avaya made a thorough, sustained case for the legitimacy and
    procompetitiveness of its actions and did not pull any punches
    in lambasting TLI’s conduct. Accordingly, I think it quite
    unlikely that labeling TLI’s conduct “unlawful” on top of all
    this would have changed the result.
    In a similar vein, the Majority finds taint in the
    constraints the District Court imposed on the evidence Avaya
    presented at trial. The Majority notes that Avaya “points to
    two examples in particular” of how the District Court’s
    judgment as a matter of law “hindered its ability to present
    evidence in its defense against the antitrust claims.”6 Majority
    Op. 75. The first is the District Court’s warning that Avaya
    could not “tell the jury” that TLI’s means of accessing Avaya
    PBX systems was “illegal” during its cross-examination of
    TLI’s CEO. App. 4440. My colleagues concede that “the
    Court did allow the line of questions,” Majority Op. 75,
    which was not directed toward criticizing TLI’s access
    practices, but rather, was offered to demonstrate that Avaya’s
    policy toward unauthorized service providers was consistent
    and business realities and that the Business Partner program
    enhanced competition in the marketplace; that its concerns
    about unauthorized PBX maintenance providers with no
    relationship to Avaya were legitimate because poor-quality
    servicing of Avaya PBX’s could damage the Avaya brand;
    and that TLI was the party with questionable practices given
    its choice to pursue Avaya maintenance customers without
    authorization rather than “play” by the “rules,” 
    id. at 15767.
           6
    In doing so, it fails to mention that these two
    examples are drawn exclusively from Avaya’s reply brief—
    the first time Avaya mentioned them in this appeal. Compare
    Majority Op. 75, with Avaya Reply Br. 19.
    11
    with industry practice and did not cause TLI any
    anticompetitive harm. Second, the Majority is troubled by the
    trial judge’s rather innocuous caveat to Avaya when
    examining its economics expert to “[s]tay away from trying
    to, in effect, contradict anything I’ve already decided.” App.
    4587. The Court again allowed Avaya’s line of questioning,
    deeming it “fair game” and unrelated to any allegations of
    illegality. App. 4586. This is unsurprising, given that the
    expert’s testimony was directed toward showing that TLI had
    in fact benefited from Avaya’s allegedly anticompetitive
    conduct because its Business Partners program made TLI the
    only independent game in town. I am at a loss to see how the
    ability to call TLI’s conduct “illegal” would have
    meaningfully advantaged Avaya in these lines of inquiry. And
    even if there were instances in which this characterization
    would have been of rhetorical benefit to Avaya, it would not
    have changed the substance of Avaya’s procompetitive-
    justification argument.
    Finally, I am not persuaded that the District Court’s
    instruction that it was not “unlawful,” App. 615, for TLI to
    access Avaya’s maintenance software tainted the jury’s
    consideration of whether the FUD letters constituted
    anticompetitive conduct. Among other things, these letters
    told Avaya customers that accessing PBX and PDS systems
    through unauthorized service providers “is a violation of
    federal and state laws and could result in civil and criminal
    liability and penalties” and that Avaya would “take all
    necessary legal action against violators.” App. 6945; see also
    App. 3904–05, 3940, 4057–58, 7307. And with respect to
    these letters, the Court instructed the jury that “the law does
    not allow [TLI’s] injury to be based on . . . Avaya’s
    dissemination of truthful statements.” App. 621.
    12
    Even if the jury had not been instructed that
    unauthorized access to Avaya software was not illegal, it is
    unlikely that it would have reached a different verdict.
    Avaya’s own witnesses admitted that they had no idea
    whether there was any legal basis for the letters Avaya sent to
    its PBX customers stating that unauthorized use of
    maintenance service permissions and logins “violat[es] . . .
    federal and state laws” and “could result in civil and criminal
    penalties.” And they conceded that Avaya did not actually
    plan to sue its customers. App. 3904–05, 3940, 4057–58.
    Even if some of the threats Avaya issued in its FUD letters
    might have been rooted in truth (the fact that use of an
    unauthorized service provider could result in the loss of
    certain services only provided by Avaya and its Business
    Partners certainly was), the jury’s inescapable conclusion was
    that at least some of these threats were not true. Indeed, in
    defending the letters, Avaya focused on the obvious truths
    (Avaya-exclusive benefits, TLI’s unauthorized status, etc.)
    yet conceded “the fact that a private party can’t possibly
    pursue criminal liability,” which is “for the public
    authorities.” Tr. 15871. Avaya characterized this
    misstatement of law as “unfortunate language,” id.; the jury
    surely recognized this as a euphemism for “not true.” Simply
    put, it was obvious to any fair-minded reader that the FUD
    letters were over-the-top, at least partially baseless, and
    threats that couldn’t fairly be described as “legal opinion.”
    Avaya Br. 66. I do not perceive a high probability that the
    jury would have found them kosher had it known that a
    customer’s hiring an unauthorized service provider might
    amount to a breach of contract. After all, it was instructed that
    even if “a truthful statement is coupled or limited with an
    13
    untruthful statement, the truthful statement loses its protection
    and can underlie an injury.” App. 621.7
    7
    Avaya’s primary attack on the FUD issue is that the
    jury instructions misstated the law by failing to inform the
    jury of “a presumption” assigning de minimis competitive
    effect to false statements that antitrust plaintiffs “must
    overcome” by meeting a six-factor test if they are to show a
    FUD practice to be anticompetitive. Avaya Br. 64 (citing
    American Prof’l Testing Serv. v. Harcourt Brace Jovanovich
    Legal & Prof’l Publ’ns, 
    108 F.3d 1147
    , 1152 (9th Cir. 1997)).
    Because our Court is not among those that have adopted this
    presumption and six requirements, see, e.g., Maurice E.
    Stucke, How Do (and Should) Competition Authorities Treat
    A Dominant Firm’s Deception?, 63 SMU L. Rev. 1069, 1086
    (2010), I would hold that the instructions were fine. I would
    also conclude that there was sufficient evidence for the jury to
    find the FUD letters anticompetitive, especially given that
    such a finding has stronger foundation “when . . . combined
    with other anticompetitive acts” by Avaya. W. Penn
    Allegheny Health Sys., Inc. v. UPMC, 
    627 F.3d 85
    , 109 n.14
    (3d Cir. 2010).
    To the extent that sufficient evidence also needed to
    support TLI’s other theory of liability (anticompetitive refusal
    to deal) given that the general verdict form does not indicate
    which of Avaya’s allegedly anticompetitive acts formed the
    basis for the verdict, I would hold—with some reservation—
    that it does. The District Court’s instructions were consistent
    with the Supreme Court’s precedents setting forth the
    “limited circumstances in which a firm’s unilateral refusal to
    deal with its rivals can give rise to antitrust liability,” Pac.
    Bell Tel. Co. v. Linkline Commc’ns, Inc., 
    555 U.S. 438
    , 448
    14
    *      *      *
    The Majority upends a sound verdict—reached after a
    decade of litigation and seven months of trial—based on a
    few snippets mentioned only in passing in Avaya’s opening
    brief. The Majority picks up the dropped ball and runs with it,
    imbuing Avaya’s taint argument with force it never pressed in
    its opening brief. And even had it done so, I would not hold
    that any error the District Court may have committed in the
    second month of the trial was fatal to the whole enterprise.
    Accordingly, I respectfully dissent from the decision to vacate
    the judgment in favor of TLI on its counterclaim for Avaya’s
    pre-2008 attempted monopolization of the PBX maintenance
    aftermarket.
    (2009), and my review of the record leads me to conclude that
    TLI provided that “minimum quantum of evidence from
    which a jury might reasonably afford relief.” Starceski v.
    Westinghouse Elec. Corp., 
    54 F.3d 1089
    , 1095 (3d Cir. 1995)
