    2                    AQUA SHIELD   v. INTER POOL COVER TEAM
    Before WALLACH, TARANTO, and CHEN, Circuit Judges.
    TARANTO, Circuit Judge.
    Aqua Shield sued Inter Pool Cover Team, Alukov Hz
    spol. s.r.o., Alukov spol. s.r.o., and Pool & Spa Enclosures
    (collectively, IPC) for infringement of 
    U.S. Patent No. 6,637,160
    . Aqua Shield won summary judgment that IPC
    infringed and that no claim was invalid. A bench trial led
    eventually to determinations that Aqua Shield was enti-
    tled to damages in the form of a royalty of $10,800 and
    that IPC had not been willful in its infringement. Aqua
    Shield appeals the amount of the royalty award and the
    finding of no willfulness that led to the denial of enhanced
    damages and attorney’s fees. For the reasons set forth
    below, we vacate the district court’s decision on those
    issues, affirm on one narrow infringement issue also
    raised by Aqua Shield, and remand for further proceed-
    ings consistent with this opinion.
    BACKGROUND
    The ’160 patent claims enclosures designed to cover
    pools or create sun rooms. The enclosures consist of
    arched sections that can slide over or under one another
    to enclose or expose the encompassed area as desired.
    The inventor, Bob Brooks, is the chief executive officer of
    Aqua Shield, to which he assigned ownership of the
    patent.
    In 2005, Aqua Shield sued IPC in the Eastern District
    of New York, alleging that IPC, by importing and selling
    pool enclosures, was infringing claims 1–16 of the ’160
    patent. The district court in New York denied the re-
    quested preliminary injunction because Aqua Shield
    lacked information needed to show a likelihood of success
    on the merits and because of questions about personal
    jurisdiction over the defendants. Eventually, the case was
    AQUA SHIELD   v. INTER POOL COVER TEAM                   3
    transferred to the District of Utah. Aqua Shield, Inc. v.
    Inter Pool Cover Team, No. 05 CV 4880(CBA), 
    2009 WL 29312
    , at *3 (E.D.N.Y. Jan. 5, 2009).
    Aqua Shield moved for summary judgment of in-
    fringement based on IPC’s sales of various enclosure
    models. One allegation involved an installation in Utah
    (the Utah Installation).      IPC responded with non-
    infringement arguments only as to claims 10 and 15, not
    the other fourteen asserted claims. The district court held
    that there was no genuine issue of fact about IPC’s in-
    fringement of all claims except claim 15, and therefore
    entered summary judgment of infringement of claims 1–
    14 and 16. Aqua Shield, Inc. v. Inter Pool Cover Team,
    
    830 F. Supp. 2d 1285
    , 1291 (D. Utah 2011). Aqua Shield
    later dropped its allegation of infringement of claim 15,
    and it presented no infringement issues at the later trial.
    With respect to invalidity, the parties filed cross-
    motions for summary judgment. As to anticipation, the
    district court ruled that IPC failed to “compare[] the
    construed claims of the ’160 patent to the prior art” and
    did “not introduce[] evidence showing that the [prior art]
    discloses each limitation of the ’160 patent.” Aqua Shield,
    Inc. v. Inter Pool Cover Team, No. 2:09-CV-13 TS, 
    2013 WL 164244
    , at *4 (D. Utah Jan. 15, 2013). As to obvious-
    ness, the court ruled that IPC did “not argue[] obvious-
    ness on a claim-by-claim basis,” “try to show that all of
    the elements of even a single claim in the ’160 patent
    were made obvious by prior art,” or “articulate[] why a
    person of ordinary skill in the art would have been moti-
    vated to combine the prior art to produce the claimed
    invention.” 
    Id. at *5
    . For those reasons the district court
    granted summary judgment in favor of Aqua Shield
    regarding validity. 
    Id.
     Neither party appeals the sum-
    mary judgment rulings (except for one discrete infringe-
    ment issue concerning the “Elegant” model).
    4                    AQUA SHIELD   v. INTER POOL COVER TEAM
    The district court next conducted a two-day bench tri-
    al on issues concerning relief. In one ruling not chal-
    lenged on appeal, the court found that Aqua Shield failed
    to prove lost-profit damages. Aqua Shield, Inc. v. Inter
    Pool Cover Team, No. 2:09-CV-13 TS, slip. op. at 13–17
    (D. Utah Aug. 14, 2013) (Initial Damages Op.). The court
    also granted Aqua Shield a permanent injunction against
    IPC’s infringement. 
    Id.
     at 31–38.
    The court rejected not only Aqua Shield’s claim for
    lost-profits damages but also its claim for damages in the
    form of a reasonable royalty. 
    Id.
     at 17–28. It determined
    that several familiar considerations favored a “higher”
    royalty rate, 
    id.
     at 19–23 (citing Georgia-Pacific Corp. v.
    U.S. Plywood Corp., 
    318 F. Supp. 1116
    , 1120 (S.D.N.Y.
    1970), modified, 
    446 F.2d 295
     (2d Cir. 1971)), but that it
    lacked sufficient evidence from which to determine an
    initial royalty rate, 
    id.
     at 26–27 (“Although some of the
    factors weigh in favor of a ‘higher’ royalty rate, the Court
    is without sufficient evidence to determine what that rate
    should be higher than.”). The court thus awarded Aqua
    Shield no damages at all. 
    Id.
     at 27–28.
    The court also found no willfulness on IPC’s part. The
    court determined that, until summary judgment of in-
    fringement was granted, IPC had a reasonable belief that
    its products were non-infringing, based on the New York
    district court’s denial of Aqua Shield’s motion for a pre-
    liminary injunction. Id. at 29. And after summary judg-
    ment of infringement was granted, the court found, IPC
    “made a good faith effort to design around the [p]atent.”
    Id. Based on those conclusions, the court found that IPC
    had not willfully infringed the ’160 patent. Id. Further
    concluding that IPC did not otherwise “act in bad faith,
    engage[] in litigation misconduct, or exhibit[] bad behav-
    ior,” the court determined that this was not an “excep-
    tional case” within the meaning of 
    35 U.S.C. § 285
     and so
    denied Aqua Shield’s motion for fees. 
    Id.
     at 28–30.
    AQUA SHIELD   v. INTER POOL COVER TEAM                      5
    Aqua Shield then moved to alter the district court’s
    judgment. The district court reassessed several of the
    conclusions it had reached, but it changed only the no-
    royalty finding. Aqua Shield, Inc. v. Inter Pool Cover
    Team, No. 2:09-CV-13 TS, 
    2013 WL 6410975
    , at *1, *5–6
    (D. Utah Dec. 9, 2013). Noting 
    35 U.S.C. § 284
    ’s “clear”
    instruction “that the Court ‘shall’ award damages ‘in no
    event less than a reasonable royalty,’ ” 
    id. at *5
    , the court
    relied on evidence of IPC’s profits on past infringing sales
    as the foundation for a royalty calculation, 
    id.
     at *3–5.
    The court found that IPC’s net profit on infringing sales
    had been five percent, amounting to $135,000. 
    Id. at *5
    .
    Then, “[c]onsidering the[] benefits [of the patented inven-
    tion], while still allowing Defendants a profit on infring-
    ing sales,” the court stated that, in a hypothetical
    negotiation occurring before infringement began, IPC
    would have been willing to pay a royalty of five percent of
    those net profits, but the court raised that figure to eight
    percent to reflect the Georgia-Pacific considerations that
    pointed toward a higher royalty. 
    Id.
     The result was an
    award to Aqua Shield of $10,800 in damages. 
    Id.
    Aqua Shield now appeals, principally challenging the
    royalty-award methodology and the rejection of willful-
    ness. We have jurisdiction under 
    28 U.S.C. § 1295
    (a)(1).
    DISCUSSION
    A. Reasonable Royalty
    The amount of damages awarded to a patentee, when
    fixed by the district court, is a factual finding reviewed for
    clear error. SmithKline Diagnostics, Inc. v. Helena Labs.
    Corp., 
    926 F.2d 1161
    , 1164 (Fed. Cir. 1991). But the
    methodology underlying the district court’s damages
    computation is reviewed for abuse of discretion. 
    Id.
     A
    district court abuses its discretion when it “ma[kes] a
    clear error of judgment in weighing relevant factors or
    6                    AQUA SHIELD   v. INTER POOL COVER TEAM
    exercise[s] its discretion based upon an error of law or
    clearly erroneous factual findings.” Genentech, Inc. v.
    Novo Nordisk A/S, 
    108 F.3d 1361
    , 1364 (Fed. Cir. 1997).
    In the damages context, therefore, we examine the meth-
    odology for consistency with the legal principles defining a
    reasonable royalty.
    After making a finding of infringement, “the court
    shall award the claimant damages adequate to compen-
    sate for the infringement, but in no event less than a
    reasonable royalty for the use made of the invention by
    the infringer.” 
    35 U.S.C. § 284
    . The “value of what was
    taken”—the value of the use of the patented technology—
    measures the royalty. Dowagiac Mfg. Co. v. Minn. Moline
    Plow Co., 
    235 U.S. 641
    , 648 (1915). A traditional heuris-
    tic for assessing this market value is to posit a “hypothet-
    ical negotiation” between the patentee and adjudicated
    infringer and to “attempt[] to ascertain the royalty upon
    which the parties would have agreed had they successful-
    ly negotiated an agreement just before infringement
    began.” Lucent Techs., Inc. v. Gateway, Inc., 
    580 F.3d 1301
    , 1324 (Fed. Cir. 2009). The inquiry, besides being
    hypothetical, involves approximation: “[t]he hypothetical
    negotiation tries, as best as possible, to recreate the ex
    ante licensing negotiation scenario and to describe the
    resulting agreement.” 
    Id. at 1325
    .
    Aqua Shield does not challenge the district court’s de-
    cision to use a hypothetical-negotiation approach, but it
    does challenge how the court applied that approach. We
    agree with that challenge in part. The district court
    correctly noted that the infringer’s actual profits earned
    during the period of infringement can be relevant to the
    inquiry, see Trans-World Mfg. Corp. v. Al Nyman & Sons,
    Inc., 
    750 F.2d 1552
    , 1568 (Fed. Cir. 1984), but it erred in
    the use it made of IPC’s profit figures.
    AQUA SHIELD   v. INTER POOL COVER TEAM                    7
    What an infringer’s profits actually turned out to have
    been during the infringement period may be relevant, but
    only in an indirect and limited way—as some evidence
    bearing on a directly relevant inquiry into anticipated
    profits. Thus, when the infringer is a profit-making
    enterprise, a “reasonable royalty is the amount that ‘a
    person, desiring to manufacture[, use, or] sell a patented
    article, as a business proposition, would be willing to pay
    as a royalty and yet be able to make[, use, or] sell the
    patented article, in the market, at a reasonable profit.’ ”
    
    Id.
     (bracketed changes in original; quoting earlier author-
    ity). In hypothetical-negotiation terms, the core economic
    question is what the infringer, in a hypothetical pre-
    infringement negotiation under hypothetical conditions,
    would have anticipated the profit-making potential of use
    of the patented technology to be, compared to using non-
    infringing alternatives. If a potential user of the patented
    technology would expect to earn X profits in the future
    without using the patented technology, and X + Y profits
    by using the patented technology, it would seem, as a
    prima facie matter, economically irrational to pay more
    than Y as a royalty—paying more would produce a loss
    compared to forgoing use of the patented technology. See
    Riles v. Shell Exploration & Prod. Co., 
    298 F.3d 1302
    ,
    1312 (Fed. Cir. 2002) (“The economic relationship between
    the patented method and non-infringing alternative
    methods, of necessity, would limit the hypothetical nego-
    tiation.”); Dowagiac, 
    235 U.S. at 648
     (it is “permissible to
    show the value [of using the patented technology] by
    proving what would have been a reasonable royalty,
    considering the nature of the invention, its utility and
    advantages, and the extent of the use involved” (emphasis
    added)); Suffolk Co. v. Hayden, 70 U.S. (3 Wall.) 315, 319–
    20 (1865).
    The hypothetical negotiation is hypothetical not only
    because, in the typical case, no successful pre-
    infringement negotiation ever occurred, but also because
    8                    AQUA SHIELD   v. INTER POOL COVER TEAM
    the negotiation is constructed on hypothetical assump-
    tions. Most basically, the method assumes infringement
    and validity of the patents and willingness of the parties
    to negotiate an agreement. See Lucent, 
    580 F.3d at 1325
    .
    Another hypothetical assumption, bearing particularly on
    the anticipated-profits inquiry, abstracts away from the
    particular infringer’s degree of efficiency. An especially
    inefficient infringer—e.g., one operating with needlessly
    high costs, wasteful practices, or poor management—is
    not entitled to an especially low royalty rate simply
    because that is all it can afford to pay without forfeiting
    or unduly limiting its profit if it uses the patented tech-
    nology rather than alternatives. Thus, the royalty the
    particular infringer could profitably pay by going about its
    business in its particular way does not set the market
    value that the hypothetical negotiation aims to identify.
    See Mars, Inc. v. Coin Acceptors, Inc., 
    527 F.3d 1359
    , 1373
    (Fed. Cir. 2008), modified in other respect, 
    577 F.3d 1377
    (Fed. Cir. 2009); Monsanto Co. v. Ralph, 
    382 F.3d 1374
    ,
    1384 (Fed. Cir. 2004); Golight, Inc. v. Wal-Mart Stores,
    Inc.,

    (Fed. Cir. 1989).
    Real-world application of this conceptual structure of-
    ten involves “approximation and uncertainty,” Lucent, 
    580 F.3d at 1325
     (internal quotation marks omitted), and the
    ultimate royalty determination must reflect the two-sided
    nature of the posited negotiation. 1 The inquiry, besides
    1   In copyright law, which uses a hypothetical nego-
    tiation to estimate fair market value in a similar way, see
    Gaylord v. United States, 
    678 F.3d 1339
    , 1343 (Fed. Cir.
    2012), the Ninth Circuit recently wrote:
    AQUA SHIELD   v. INTER POOL COVER TEAM                    9
    being hypothetical, asks about a comparative business
    prediction in an uncertain, complex world, and many
    variables may affect the hypothetical forecast, including
    costs and availability of non-infringing alternatives, the
    patented technology’s role in the firm’s (expected) overall
    business, and the (expected) actions of competing firms in
    the market. Moreover, various kinds of evidence, such as
    licenses, business prognostications, and information about
    cost savings or value enhancements compared to alterna-
    tives, where such evidence is reliable, relevant, and not
    unduly prejudicial, may be used in the inquiry to deter-
    mine “the economic value of the patented technology in
    the marketplace” at the relevant time. LaserDynamics,
    Inc. v. Quanta Computer, Inc., 
    694 F.3d 51
    , 79 (Fed. Cir.
    2012). But we do not have before us broad questions
    Fair market value in a voluntary licensing
    transaction between arms-length parties ordinari-
    ly lies somewhere between the two poles of cost to
    the seller and benefit to the buyer. That is, the
    seller will not ordinarily charge less for a license
    than its anticipated cost, and the buyer will not
    ordinarily pay more for a license than its antici-
    pated benefit. In the case of a hypothetical li-
    cense, it is often difficult to determine what, at
    the time of the infringement, the seller and buyer
    thought would be their respective cost and benefit.
    Further, even if the cost and benefit can be de-
    termined with some degree of certainty, it is often
    difficult to determine the range between the two
    poles of cost and benefit within which the parties
    would likely have settled.
    Oracle Corp. v. SAP AG, 
    765 F.3d 1081
    , 1089 (9th Cir.
    2014).
    10                    AQUA SHIELD   v. INTER POOL COVER TEAM
    about what evidence meets admissibility standards or
    would support a sustainable royalty award.
    We deal here only with a challenge to the soundness
    of the district court’s particular use of IPC’s profits in its
    rationale. For purposes of Aqua Shield’s challenge, two
    points are key. First, anticipated incremental profits
    under the hypothesized conditions are conceptually cen-
    tral to constraining the royalty negotiation, as recognized
    in Trans-World Mfg., 
    750 F.2d at 1568
    .               Second,
    “[e]vidence of the infringer’s actual profits generally is
    admissible as probative of his anticipated profits.” Id.; see
    Interactive Pictures Corp. v. Infinite Pictures, Inc., 
    274 F.3d 1371
    , 1385 (Fed. Cir. 2001); see also Sinclair Ref. Co.
    v. Jenkins Petrol. Process Co., 
    289 U.S. 689
    , 698 (1933)
    (post-infringement evidence can be a relevant “book of
    wisdom”); Lucent, 
    580 F.3d at 1333
    .
    Contrary to Aqua Shield’s broader contention, there-
    fore, the district court did not err in considering IPC’s
    profits. But it did err in treating the profits IPC actually
    earned during the period of infringement as a royalty cap.
    That treatment incorrectly replaces the hypothetical
    inquiry into what the parties would have anticipated,
    looking forward when negotiating, with a backward-
    looking inquiry into what turned out to have happened.
    See Interactive Pictures, 
    274 F.3d at 1385
     (expectations
    govern, not actual results).
    The district court’s analysis also incorrectly replaces
    the inquiry into the parties’ anticipation of what profits
    would be earned if a royalty (of amounts being negotiated)
    were to be paid with an inquiry into what profits were
    earned when IPC was charging prices without accounting
    for any royalty. Thus, the district court seems to have
    simply assumed that any royalty paid by IPC would have
    directly reduced its profits, dollar for dollar. But that
    would not be true, in general, if IPC could have raised its
    AQUA SHIELD   v. INTER POOL COVER TEAM                   11
    prices (over what it actually charged for infringing sales)
    to account (fully or partly) for a royalty payment. The
    district court did not find, and IPC has not argued here,
    that IPC was selling in a perfectly competitive market in
    which it was forced to act as a pure price-taker. We have
    not been shown proof that this case is different from the
    typical one in which pricing might be adjusted to account
    for a royalty based on sales price. Indeed, IPC has not
    pointed to any evidence supporting the district court’s
    conclusion that a royalty should be a percentage of profits
    rather than sales revenues. 2
    In Douglas Dynamics, LLC v. Buyers Prod. Co., 
    717 F.3d 1336
    , 1346 (Fed. Cir. 2013), this court explained:
    “The infringer’s selling price can be raised if necessary to
    accommodate a higher royalty rate, and indeed, requiring
    the infringer to do so may be the only way to adequately
    compensate the patentee for the use of its technology.”
    The court held, for that reason, that “the district court
    clearly erred by ensuring the ongoing royalty rate it
    awarded would ‘leave some room for profit’ by [the in-
    fringer] at its current prices.” 
    Id.
     On the record before
    us, we conclude that the district court committed the
    same error in the present case.
    We vacate the district court’s royalty calculation and
    remand for redetermination in a manner consistent with
    this opinion. On remand, the court should consider all
    relevant record evidence, including the advantages of the
    2    Evidence of the parties’ abandoned settlement ne-
    gotiations refers to percentages of “selling prices.” J.A.
    329. One IPC witness may have recognized a sales-based
    royalty, though the testimony leaves room for interpreta-
    tion. J.A. 239–40. On appeal, IPC has not specifically
    answered Aqua Shield’s assertion that the sale price is
    the appropriate base on this record.
    12                    AQUA SHIELD   v. INTER POOL COVER TEAM
    patented product, the ease and cost of designing around
    the claimed invention, and the relevance of IPC’s actual
    profits to what IPC’s expectations would have been in a
    hypothetical negotiation. Our correction of the erroneous
    focus on the net profits IPC actually earned may require
    reconsideration of aspects of the district court’s analysis
    we have not specifically discussed. For example, in reject-
    ing the testimony of Mr. Brooks, the court relied in part
    on its focus on IPC’s actual profits, which we hold to be
    erroneous. Initial Damages Op. at 26. The district court
    also should reconsider the relevance of Aqua Shield’s
    evidence regarding IPC’s gross profits now that the in-
    quiry is not constrained by the erroneous focus on IPC’s
    net profits.
    B. Willful Infringement
    To prove that its patent was willfully infringed, a pa-
    tentee must make two related showings. First, it must
    “show by clear and convincing evidence that the infringer
    acted despite an objectively high likelihood that its ac-
    tions constituted infringement of a valid patent.” In re
    Seagate Tech., LLC, 
    497 F.3d 1360
    , 1371 (Fed. Cir. 2007).
    Second, “the patentee must also demonstrate that this
    objectively-defined risk (determined by the record devel-
    oped in the infringement proceeding) was either known or
    so obvious that it should have been known to the accused
    infringer.”

     The first issue is legal, with our review de
    novo, Bard Peripheral Vascular, Inc. v. W.L. Gore &
    Assocs., Inc., 
    682 F.3d 1003
    , 1006–07 (Fed. Cir. 2012), and
    the second issue is factual, see 
    id. at 1008
    , which means
    clear-error review in a bench-trial case. Our disposition
    here, however, does not turn on the standard of review.
    The district court did not lay out its willfulness analy-
    sis in Seagate’s two-part terms. See Initial Damages Op.
    at 10–11, 29–30; Aqua Shield, 
    2013 WL 6410975
    , at *1–2.
    And with regard to infringement that occurred before the
    AQUA SHIELD   v. INTER POOL COVER TEAM                    13
    court’s decision granting Aqua Shield summary judgment
    of infringement, the court gave only one reason for con-
    cluding that “Defendants[] reasonably believed that their
    products did not infringe the ’160 Patent”—namely, that
    “the Eastern District of New York denied Aqua Shield’s
    motion for preliminary injunction.” Initial Damages Op.
    at 10. The court gave no additional reasons when, in
    ruling on Aqua Shield’s post-judgment motion, it reiterat-
    ed that IPC “prudently conducted [itself] with confidence
    that a court might hold the patent invalid or not in-
    fringed.” Aqua Shield, 
    2013 WL 6410975
    , at *2.
    Our opinion in Seagate expressly connects findings of
    willfulness to preliminary-injunction rulings. Seagate,
    
    497 F.3d at 1374
     (“A substantial question about invalidity
    or infringement is likely sufficient not only to avoid a
    preliminary injunction, but also a charge of willfulness
    based on post-filing conduct.”). But it states no rigid rule,
    and it notes that preliminary injunctions can be denied
    even when a defendant has not raised “substantial ques-
    tion[s] about invalidity or infringement.” See 
    id.
     In a
    later willfulness determination, the significance of a
    preliminary-injunction denial depends on why the prelim-
    inary injunction was denied. In this case, the Eastern
    District of New York’s decision to deny Aqua Shield’s
    motion for a preliminary injunction cannot reasonably be
    read to support a conclusion that any substantial basis
    existed for doubting infringement or validity. The New
    York court denied Aqua Shield’s motion because of per-
    sonal-jurisdiction questions and because Aqua Shield
    lacked sufficient knowledge of IPC’s product to make the
    required showing of a likelihood of success on the merits.
    Personal jurisdiction does not speak to infringement or
    validity at all. And Aqua Shield’s ignorance of IPC’s
    products appears irrelevant to a validity analysis and
    does not indicate what an infringement analysis of those
    products would show once the details of those products
    were fully known—as they were all along to IPC. The
    14                   AQUA SHIELD   v. INTER POOL COVER TEAM
    denial of Aqua Shield’s motion for a preliminary injunc-
    tion is thus a legally insufficient reason for determining
    that IPC did not willfully infringe.
    With respect to the willfulness of any infringement
    that occurred after summary judgment of infringement,
    the evidence cited by the district court stops short of
    demonstrating that IPC did in fact design around the ’160
    patent and, if so, when. The court pointed to evidence
    that IPC instructed its factory to fix the end panels of its
    pool enclosures in place, in a manner it believed to avoid
    the patent’s claims. Initial Damages Op. at 11; Aqua
    Shield, 
    2013 WL 6410975
    , at *2. Questions remain about
    whether that change was actually implemented or wheth-
    er the resulting products avoided infringement. Both
    inquiries are relevant to the issue of willfulness. They
    may also bear on the royalty issue, because they may be
    relevant to the ease and cost of designing around the
    patented technology.
    We therefore vacate the court’s decision that IPC did
    not willfully infringe and remand for an analysis that
    conforms to Seagate’s standard. 
    497 F.3d at 1371
    . We do
    not reach an ultimate conclusion ourselves. We observe,
    however, that Seagate’s first requirement focuses on
    whether the infringer’s defenses, as ultimately presented
    to the court, were reasonable. Bard, 682 F.3d at 1008. On
    remand, the district court should focus on IPC’s defenses
    as articulated during the infringement and invalidity
    proceedings—during which IPC presented no infringe-
    ment defenses for claims 2–9, 11–14, or 16, Aqua Shield,
    830 F. Supp. 2d at 1287–89, and presented no element-by-
    element argument for invalidity, Aqua Shield, 
    2013 WL 164244
    , at *4–5. If the court finds that the defenses were
    objectively unreasonable, in the sense that no “reasonable
    litigant could realistically expect” them to succeed, Bard,
    682 F.3d at 1008 (internal quotation marks omitted), it
    should proceed to consider Seagate’s second requirement.
    AQUA SHIELD   v. INTER POOL COVER TEAM                    15
    On that issue, we note that the objective baselessness of
    an infringer’s defenses, assessed on the litigation record,
    may have a strong bearing on whether the “objectively-
    defined risk” of infringement “was either known or so
    obvious that it should have been known to the accused
    infringer.” Seagate, 
    497 F.3d at 1371
    ; see Kilopass Tech.,
    Inc. v. Sidense Corp., 
    738 F.3d 1302
    , 1314 (Fed. Cir. 2013)
    (under the then-similar approach in the fee-shifting
    context, “[o]bjective baselessness alone can create a
    sufficient inference of bad faith to establish exceptionality
    under § 285, unless the circumstances as a whole show a
    lack of recklessness on the patentee’s part”).
    If the court determines on remand that IPC willfully
    infringed Aqua Shield’s patent, it should reconsider its
    decision to deny enhanced damages and attorney’s fees.
    C. The “Elegant” Model
    One issue remains. Aqua Shield argues that the dis-
    trict court erroneously omitted one of IPC’s pool-enclosure
    models—the “Elegant”—from the calculation of IPC’s
    infringing sales and, thus, from the royalty award and
    injunction. We reject this challenge.
    Aqua Shield argues that, in the summary-judgment
    proceedings, it asserted that the Utah Installation in-
    fringed and that it was an Elegant model that was in-
    stalled. But the district court, while finding that the
    Utah Installation infringed, made no finding that the
    Utah installation was an Elegant model. Aqua Shield,
    830 F. Supp. 2d at 1291; Initial Damages Op. at 6; Aqua
    Shield, 
    2013 WL 6410975
    , at *6. And the subsequent
    trial involved no infringement issues, but was limited to
    issues concerning relief. Aqua Shield thus never obtained
    a finding of infringement by the Elegant model, and there
    was no error in the district court’s refusal to include that
    model in its royalty calculation or injunction.

    CONCLUSION
    For the foregoing reasons, we vacate the district
    court’s royalty award, non-willfulness finding, and denial
    of enhanced damages and attorney’s fees. We remand the
    case for further proceedings consistent with this opinion.
    Costs are awarded to Aqua Shield.
