    Before DYK, MOORE, and O’MALLEY, Circuit Judges.
    Opinion for the court filed by Circuit Judge O’Malley.
    Circuit Judge Dyk concurs.
    O’MALLEY, Circuit Judge.
    In this patent case, Meyer Intellectual Properties
    Limited and Meyer Corporation, U.S. (collectively,
    “Meyer”) filed suit against Bodum, Inc. (“Bodum”) in the
    United States District Court for the Northern District of
    Illinois, alleging that Bodum infringed two of Meyer’s
    patents, both of which are directed to a method for froth-
    ing milk: U.S. Patent Nos. 5,780,087 (“the ’087 Patent”)
    and 5,939,122 (“the ’122 Patent”) (collectively, “the pat-
    ents-in-suit”). Bodum counterclaimed for declaratory
    judgment of noninfringement and invalidity.
    The district court granted Meyer’s motions for sum-
    mary judgment that Bodum’s products infringed the
    patents-in-suit. Before proceeding to trial, the district
    court granted Meyer’s motions in limine prohibiting
    Bodum from: (1) introducing and relying on certain prior
    art; (2) presenting certain testimony relating to that prior
    art; and (3) introducing any evidence to support its ineq-
    uitable conduct claims. The jury returned a verdict in
    favor of Meyer, finding that the patents-in-suit were not
    proven to be invalid, finding that Bodum’s infringement
    was willful, and awarding Meyer damages in the amount
    of $50,000.     The district court subsequently denied
    Bodum’s post-trial motions for judgment as a matter of
    law (“JMOL”) and granted Meyer’s motion requesting
    enhanced damages and attorney fees.
    Bodum appeals from the district court’s final judg-
    ment awarding damages and attorney fees to Meyer in
    the amount of $906,487.56. Judgment, Meyer Intellectual
    Props. Ltd. v. Bodum, Inc., No. 06-cv-6329 (N.D. Ill. Feb.

    16, 2011), ECF No. 237. On appeal, Bodum challenges
    several of the court’s rulings. Specifically, Bodum chal-
    lenges the district court’s decisions: (1) granting summary
    judgment in favor of Meyer on infringement; (2) granting
    Meyer’s motions in limine precluding Bodum from pre-
    senting certain prior art and testimony at trial;
    (3) denying Bodum’s motion for JMOL that Bodum did
    not willfully infringe the patents-in-suit; (4) enhancing
    damages and awarding attorney fees in Meyer’s favor;
    and (5) denying Bodum’s renewed motion for JMOL and
    motion to alter the court’s infringement decisions. For the
    reasons explained below, we reverse-in-part, vacate-in-
    part, and remand.
    BACKGROUND
    A. Factual Background
    1. The Patents-in-Suit
    Frank Brady (“Brady”) is the sole inventor of the ’087
    and ’122 Patents. For approximately ten years, from 1986
    to 1996, Brady was an independent sales representative
    for Bodum, a company that designs and sells housewares
    products, including coffee makers, milk frothers, and
    other kitchen products. Tr. of Proceedings held on Nov.
    12, 2010, Meyer Intellectual Props. Ltd. v. Bodum, Inc.,
    No. 06-6329 (N.D. Ill. Apr. 29, 2011), ECF No. 268 at
    683:14-23. In that capacity, and as the Chief Executive
    Officer of Brady Marketing Company, Inc., Brady mar-
    keted and sold a number of Bodum’s household products,
    including Bodum’s French press coffee makers. Brady
    explained that he first conceived of a frother using aera-
    tion instead of steam in the mid-1990s, and that he intro-
    duced it for sale at a trade show in May 1996. Tr. of
    Proceedings held on Nov. 10, 2010, Meyer Intellectual
    Props. Ltd. v. Bodum, Inc., No. 06-6329 (N.D. Ill. Apr. 29,
    2011), ECF No. 267 at 466:3-467:2. Around that same
    MEYER INTELL PROP   v. BODUM                             4
    time, Brady began selling his frothers through his com-
    pany BonJour, Inc. (“BonJour”).
    On September 23, 1996, Brady filed a patent applica-
    tion directed to a “Method for Frothing Liquids.” That
    application became the ’087 Patent, which issued on July
    14, 1998. During prosecution of the application that
    resulted in the ’087 Patent, the PTO examiner initially
    rejected Claim 1 as anticipated by a prior art reference:
    
    U.S. Patent No. 5,580,169
     (“the Ghidini Patent”). In
    response, Brady amended the claim to provide: (1) a
    dimensional limitation requiring that the container have
    a height that is at least two times the diameter; and (2) a
    plunger with a screen and a spring, where the spring is
    “positioned about the circumference of the plunger body
    such that the spring is biased to hold the screen in place
    in contact with, though not sealably connected to, the
    container.” With these changes, Claim 1 of the ’087
    Patent was allowed.
    While the application that resulted in the ’087 Patent
    was pending, Brady filed a continuation application that
    later became the ’122 Patent. The ’122 Patent issued on
    August 17, 1999.
    The patents-in-suit, which share a common specifica-
    tion, are directed to a method for frothing liquids such as
    milk. Specifically, the patents relate to “an apparatus
    and method for frothing, which allows the user to obtain
    foamy, frothed milk without the use of a complicated
    steamer device.” ’087 Patent col.1 ll.5-10; ’122 Patent
    col.1 ll.8-12. 1 The “Background of the Invention” explains
    that, at the time the application was filed, “[m]ost of the
    1    Despite the reference to an “apparatus” in the
    opening sections of the ’122 Patent, there are no appara-
    tus claims in that patent; only method claims are at issue
    here.
    5                                MEYER INTELL PROP   v. BODUM
    prior art foaming devices [were] complicated machines
    which involve the use of steam to aerate or foam the
    liquid.” ’087 Patent col.1 ll.12-15. The background sec-
    tion concludes with the statement that, “[w]hat is needed,
    and is lacking in the prior art, is a device to froth liquids,
    such as milk, which is simple to use, has no need for
    electricity or steam, and is relatively easy to clean and
    store.” 
    Id.
     at col.1 ll.64-67.
    Generally speaking, the claims disclose four steps:
    (1) providing a container that has a height to diameter
    aspect ratio of 2:1; (2) pouring liquid (e.g., milk) into the
    container; (3) introducing a plunger that includes at least
    a rod and plunger body with a screen; and (4) pumping
    the plunger to aerate the liquid. ’087 Patent col.5 ll.20 –
    col.6 ll.8.
    2. Bodum’s Accused Products
    Meyer accuses three of Bodum’s milk frothers of in-
    fringement: (1) the Chambord Frother Model No. 1964;
    (2) the Aerius Frother Model No. 1364; and (3) the Shin
    Bistro Frother Model No. 10492. Bodum began selling a
    first generation of accused milk frothers – referred to as
    the Version 1 frothers – in 1999. The Version 1 frothers
    departed from Bodum’s previous non-electric milk froth-
    ers in that: (1) the carafe was taller and thinner; and
    (2) the plunger had a different construction involving a
    mesh and spring design. The following images show a
    comparison between Bodum’s Version 1 Chambord
    Frother and the Figures from Meyer’s ’087 Patent:

    7                             MEYER INTELL PROP   v. BODUM
    B. Procedural History
    In May 2005, Brady sold his company – BonJour – to
    Meyer. In the sale, BonJour transferred its intellectual
    property rights to Meyer, and it is undisputed that Meyer
    owns the patents-in-suit.
    On November 20, 2006, Meyer filed suit against
    Bodum in the Northern District of Illinois, alleging in-
    fringement of the patents-in-suit. In the Complaint,
    Meyer alleged that Bodum “has been and still is using,
    selling, offering for sale and/or importing one or more
    milk frother products for frothing liquids that infringe,
    directly, indirectly, contributorily and/or by inducement”
    the ’087 Patent and the ’122 Patent. Complaint, Meyer
    Intellectual Props. Ltd. v. Bodum, Inc., No. 06-cv-6329
    MEYER INTELL PROP   v. BODUM                               8
    (N.D. Ill. Nov. 20, 2006), ECF No. 1. Meyer amended its
    complaint a year later, in November 2007, to add a claim
    for willful infringement.
    On January 19, 2007, Bodum: (1) filed an answer as-
    serting an affirmative defense of inequitable conduct; and
    (2) counterclaimed seeking a declaration that the asserted
    claims of the patents-in-suit are invalid and not infringed.
    Roughly six months after it was served with the com-
    plaint, Bodum ceased manufacturing its Version 1 froth-
    ers and transitioned to Version 2 frothers with a new
    plunger design. Bodum did not change the name or
    designation of its frother products. According to Bodum,
    “[u]nlike the Version 1 plunger, the Version 2 plunger
    does not have a spring or other biasing element that holds
    the screen against the inside wall of the container or
    housing, and the screen does not extend beyond the
    diameter of the plunger plate.” Appellant Br. 9. Instead,
    the Version 2 plunger contains an O-ring around the
    circumference of the plunger body. Bodum subsequently
    removed the O-ring from the Version 2 frother and began
    selling the new design as Version 3 in July 2008.
    1. Claim Construction
    On May 14, 2008, the district court issued its claim
    construction order. Meyer Intellectual Props. Ltd. v.
    Bodum, Inc., 
    552 F. Supp. 2d 810
     (N.D. Ill. 2008) (“Claim
    Construction Order”). In that order, the court noted that
    the parties “agree[d] on which claims are in dispute and
    have submitted a joint letter identifying the disputed
    language.” 
    Id. at 812
    . Consistent with the parties’ re-
    quest, the court limited its construction to certain lan-
    guage in Claim 1 of the ’087 Patent and Claims 1 and 10
    of the ’122 Patent. The bulk of the court’s claim construc-
    tion order is not relevant to resolution of this appeal so we
    do not discuss it in any detail. Notably, however, the
    9                              MEYER INTELL PROP   v. BODUM
    parties did not ask the court to construe the phrase “pro-
    viding a container” as it is used in Claim 1 of the patents-
    in-suit at this stage of the proceedings. See ’087 Patent
    col.5 ll.23-25 (“providing a container characterized by a
    height and a diameter, the height being at least two times
    the diameter”).
    2. Summary Judgment
    On September 2, 2008, Meyer moved for partial sum-
    mary judgment, arguing that, by providing its Version 1
    frothers along with instructions for their use, Bodum
    induced others – specifically Meyer’s own expert Albert
    Karvelis – to infringe the patents-in-suit. In response,
    Bodum argued that: (1) Meyer failed to provide sufficient
    evidence of an intent to induce infringement; (2) Bodum
    could not induce infringement because it believed in good
    faith that the Meyer patents are invalid; (3) Bodum could
    not be liable for inducement because no single third party
    could perform all the steps in the patented claims, not
    even Mr. Karvelis; and (4) even if Mr. Karvelis had per-
    formed all of the steps of the method claims, his acts could
    not be acts of “infringement” since he was acting under an
    implied license created by the umbrella of the parties’
    litigation.
    Two things are notable about the parties’ summary
    judgment filings. First, Meyer presented no evidence that
    anyone other than its own expert had directly “infringed”
    the ’087 and ’122 Patents. Second, both parties discussed
    what it meant to “provide a container” for frothing
    though, again, neither expressly sought construction of
    that term.
    On February 11, 2009, the district court granted
    Meyer’s motion for partial summary judgment, finding
    that Bodum had induced infringement of certain claims in
    the ’087 and ’122 Patents by its sales of the Version 1
    MEYER INTELL PROP   v. BODUM                            10
    frothers. Meyer Intellectual Props. Ltd. v. Bodum, Inc.,
    
    597 F. Supp. 2d 790
     (N.D. Ill. 2009) (“Summary Judgment
    Version 1”).
    Meyer then filed a second motion for partial summary
    judgment, this time arguing that Bodum’s sale of its
    Version 2 and 3 frothers both directly infringed and
    induced infringement of the ’122 Patent. 2 The court
    granted summary judgment of direct infringement and
    inducement as to the Version 2 frothers, but found genu-
    ine issues of material fact as to literal infringement with
    respect to the Version 3 frothers. Meyer Intellectual
    Props. Ltd. v. Bodum, Inc., 
    674 F. Supp. 2d 1015
    , 1022
    (N.D. Ill. 2009) (“Summary Judgment Version 2”). The
    court began by noting that the ’122 Patent includes a
    limitation that “substantially no liquid passes between
    the circumference of the plunger body and the inside wall
    of the container.” 
    Id. at 1017
    . Although Bodum at-
    tempted to design around this limitation by removing the
    O-ring from the Version 2 frother so that a greater
    amount of liquid could pass between the plunger and the
    container, Bodum “mistakenly produced and sold frothers
    with O-rings (“Version 2 frothers”) during a period that
    began about July 2007 and ran through June 2008.” 
    Id.
    Bodum argued that it could not be liable for infringe-
    ment because Meyer did not offer evidence that Bodum
    itself performed each step of the method and Meyer
    offered no evidence that its customers did so. The court
    rejected this argument and reiterated its view that, if
    Meyer’s patents are valid, Bodum’s production and sale of
    the Version 2 frothers infringe directly and induce others
    to infringe.
    2    Meyer did not assert the ’087 Patent against ei-
    ther the Version 2 or Version 3 frothers.
    11                               MEYER INTELL PROP   v. BODUM
    3. Motions in Limine
    In April 2010, Meyer filed several motions in limine.
    Specifically, Meyer sought to: (1) bar Bodum’s proffered
    expert, Robert John Anders (“Anders”), from testifying
    regarding his opinion that the patents-in-suit are invalid
    as obvious under 
    35 U.S.C. § 103
    ; (2) prevent Bodum from
    relying on evidence it claims constitutes prior art, includ-
    ing documents Anders referred to in his report;
    (3) preclude Bodum from presenting any evidence regard-
    ing its inequitable conduct defense; and (4) prevent
    Bodum from introducing what Meyer characterized as
    previously undisclosed prior art references.
    In a series of decisions, the district court granted all of
    Meyer’s motions, limiting significantly the evidence
    Bodum could introduce at trial. First, the court issued an
    order excluding Anders’ opinion on obviousness and
    preventing him from testifying on that subject because he
    “advance[d] his opinion as a mere ipse dixit: ‘Trust me – I
    know obviousness when I see it, and this is it.’” Meyer
    Intellectual Props. Ltd. v. Bodum, Inc., 
    715 F. Supp. 2d 827
    , 830 (N.D. Ill. 2010).
    Next, the district court issued an order barring
    Bodum from using prior art evidence not contained in
    Anders’ report. Meyer Intellectual Props. Ltd. v. Bodum,
    Inc., No. 06-cv-6329, 
    2010 U.S. Dist. LEXIS 56168
     (N.D.
    Ill. June 7, 2010). Looking at Anders’ report, the court
    found that it was divided into three sections – A, B, and C
    – and that, although Anders identified fifty-six items in
    Part A “as matters that [he] reviewed en route to his
    arrival at the opinions that he then sets out in Parts B
    and C,” his “ensuing opinions themselves focused solely on
    just two of those many items as the actual predicates for
    his stated conclusions.” 
    Id. at *4
    . In other words, the
    court found that Anders limited the universe of prior art
    MEYER INTELL PROP   v. BODUM                             12
    and that Bodum’s lawyers could not expand that scope.
    Finally, the court granted Meyer’s motion to preclude
    Bodum from arguing that Brady engaged in inequitable
    conduct in obtaining the patents-in-suit. Specifically, the
    court found that Bodum’s “inequitable conduct charge . . .
    failed to meet the demanding requirements” of material-
    ity and intent. 
    Id. at *6-9
    .
    Bodum moved the court to reconsider both of its or-
    ders granting Meyer’s motions in limine. In relevant
    part, Bodum argued that: (1) during discovery, Bodum
    identified and disclosed much of the contested prior art in
    its Second Supplemental Answers to Plaintiffs’ Interroga-
    tories 2 and 3; (2) it was improper for the court to use the
    Anders’ report to limit the scope of prior art upon which
    Bodum could rely at trial; (3) the Anders’ report is a
    single report with three component parts which should be
    read together; and (4) even if Bodum were limited to the
    references upon which Anders expressly relied, those
    references included a drawing of a Bodum French press
    container with dimensions which matched those disclosed
    in Meyer’s ’122 Patent.
    In a decision dated October 7, 2010, the court denied
    Bodum’s motion to reconsider. First, the court reiterated
    that Anders “considered a great deal of potentially rele-
    vant material and, having done so, settled on just two
    items as the relevant prior art.” Meyer Intellectual Props.
    Ltd. v. Bodum, Inc., No. 06-cv-6329, 
    2010 U.S. Dist. LEXIS 107169
    , at *3 (N.D. Ill. Oct. 7, 2010). Second, the
    court stated that:
    It simply will not do for Bodum to take an end run
    around its own chosen expert’s opinion by adduc-
    ing testimony from its own people, Jorgen Bodum
    and Thomas Perez, as to other items that they
    consider prior art, whether that testimony is ten-
    13                              MEYER INTELL PROP   v. BODUM
    dered under the rubric of Evid. R. 702 (the rule
    governing “expert” testimony) or of Evid. R. 701
    (the rule that gives room for opinion testimony by
    lay witnesses).
    
    Id.
     Accordingly, the court limited Bodum to only two of
    the references identified in Anders’ report: (1) United
    States Reissued Patent, No. RE37,137 (“the Ghidini
    Reissue Patent”); and (2) a Bodum French Press con-
    tainer.
    4. Jury Trial
    Beginning on November 8, 2010, the court conducted
    a jury trial to address three issues: (1) invalidity based on
    obviousness; (2) whether Bodum’s infringement of the
    asserted claims was willful; and (3) damages.
    On November 10, 2010, near the end of Meyer’s case-
    in-chief, Meyer moved the court to preclude Bodum from
    introducing and using a modern version of the Bodum 3-
    Cup French Press as prior art on grounds that: (1) Bodum
    had no corroborating evidence tying the modern version to
    that which allegedly pre-dated the Meyer patents; and
    (2) it was an attempt to backdoor the court’s prior rulings
    limiting the prior art on which Bodum could rely. The
    district court granted the motion on the second ground,
    and the Bodum 3-Cup French Press was not introduced as
    an exhibit at trial.
    Also at the end of Meyer’s case-in-chief, Bodum filed a
    motion for JMOL that it did not willfully infringe the
    asserted patents. The district court denied that motion on
    the record on November 15, 2010.
    On November 17, 2010, the jury returned a verdict in
    favor of Meyer, finding that the patents-in-suit were not
    invalid and that Bodum’s infringement was willful. The
    MEYER INTELL PROP   v. BODUM                              14
    jury awarded damages to Meyer in the requested amount
    of $50,000.
    5. Post-Trial Motions
    Following the jury verdict, Meyer filed a motion ask-
    ing the court to: (1) award treble damages pursuant to 
    35 U.S.C. § 284
    ; (2) declare this case exceptional within the
    meaning of 
    35 U.S.C. § 285
    ; and (3) award Meyer its
    attorney fees in the amount of $756,487.56. In a decision
    dated February 16, 2011, the district court granted
    Meyer’s motion, increased the jury’s damage award to
    $150,000, and awarded Meyer its full attorney fees.
    Meyer Intellectual Props. Ltd. v. Bodum, Inc., 
    764 F. Supp. 2d 1004
     (N.D. Ill. 2011) (“Decision Awarding Attor-
    ney Fees”).
    Bodum subsequently filed two post-trial motions.
    First, Bodum filed a renewed motion for JMOL, again
    asking the court to find that Bodum did not willfully
    infringe the patents-in-suit. In that motion, Bodum
    argued that: (1) it did not have knowledge of the ’087 and
    ’122 Patents prior to the filing of the complaint; (2) Meyer
    failed to move for a preliminary injunction, and thus could
    not show willful infringement under In re Seagate Tech-
    nology, LLC, 
    497 F.3d 1360
     (Fed. Cir. 2007) (en banc);
    (3) Bodum’s efforts to design around the patents-in-suit
    demonstrate that it was not objectively reckless; and
    (4) Bodum raised substantial questions of non-
    infringement and invalidity.
    Second, Bodum moved the court pursuant to Rule
    59(e) of the Federal Rules of Civil Procedure to alter its
    previous decisions granting summary judgment of in-
    fringement. In that motion, Bodum asked the court to
    revisit its prior decisions in light of this court’s December
    2010 decision in Akamai Technologies, Inc. v. Limelight

     (Fed. Cir. 2010), vacated,
    15                             MEYER INTELL PROP   v. BODUM
    419 F. App’x 989 (Fed. Cir. 2011). Specifically, in light of
    Akamai, Bodum argued that the court should withdraw
    its findings of direct infringement because: (1) Meyer
    failed to show that Bodum performed every step of the
    asserted claims; (2) the claims are incapable of being
    directly infringed by a single third party; and (3) there is
    no direct infringement under a divided infringement or
    joint infringement theory because Bodum’s customers are
    not agents of Bodum, and are not obligated to use the
    frothers in any particular way.
    The district court conducted a hearing on March 14,
    2011, and denied both of Bodum’s post-trial motions on
    the record. First, the court denied Bodum’s renewed
    JMOL for the reasons previously stated on the record at
    the conclusion of Meyer’s case in chief. With respect to
    Bodum’s Rule 59(e) motion, the district judge explained
    that he reviewed Akamai and noted that “joint liability
    may be found when one party ‘controls or directs’ the
    activities of another party.” Tr. of Proceedings held on
    Mar. 14, 2011, Meyer Intellectual Props. Ltd. v. Bodum,
    Inc., No. 06-cv-6329 (N.D. Ill. Apr. 29, 2011), ECF No.
    272, at 4:19-21. The judge then stated that the patented
    method here “has only one intended goal. That is the
    production of froth liquid such as milk. And the devices
    marketed by Bodum have exactly that function. This isn’t
    a matter of purchasers that – that where the devices that
    Bodum’s customers choose among several possible means
    of accomplishing a purpose.” Id. at 6:1-7. The court
    concluded that it “would be a solipsism if you permitted
    an escape for a party that practices the method up to the
    point of its ultimate utilization . . . .” Id. at 7:11-16.
    Accordingly, the court found no basis to reverse its prior
    rulings granting summary judgment in Meyer’s favor.

    Bodum timely appealed several of the district court’s
    decisions to this court. We have jurisdiction pursuant to
    
    28 U.S.C. § 1295
    (a)(1).
    DISCUSSION
    On appeal, Bodum argues that the district court erred
    when it: (1) granted summary judgment of direct in-
    fringement and inducement of the asserted method
    claims, despite the lack of evidence that any one party –
    including Bodum – actually performed each step of the
    asserted claims; (2) made several evidentiary rulings that
    made it impossible for Bodum to present its case;
    (3) dismissed Bodum’s affirmative defense of inequitable
    conduct on a motion in limine; and (4) denied Bodum’s
    JMOL of no willful infringement. We address each of
    these issues in turn.
    A. Infringement
    The district court issued two separate decisions grant-
    ing summary judgment that Bodum directly infringed and
    induced infringement of the patents-in-suit. First, with
    respect to Bodum’s Version 1 frothers, the court found
    that: (1) Bodum conceded direct infringement; and
    (2) whenever a Bodum customer uses its milk frother and
    follows the instructions contained therein, that customer
    directly infringes the patents-in-suit, and Bodum induces
    the same as a matter of law. Summary Judgment Ver-
    sion 1, 
    597 F. Supp. 2d at 794, 798-99
    . Bodum moved the
    district court to clarify its decision, arguing that it could
    not be a direct infringer because it only practices the first
    step of the claim – “providing a container” – and its cus-
    tomers could not be direct infringers because, while they
    practice each of the other steps, they do not practice the
    “providing” step. The district court judge conducted a
    status hearing and explained to Bodum that:
    17                              MEYER INTELL PROP   v. BODUM
    I took a look at the box that contains this plunger.
    And everything that you have done is everything
    except hold the customer’s hand on the plunger. I
    mean you know, you have given the direct – you
    have got essentially a one purpose invention. And
    you have done everything, including the first step
    to practice the thing, because again all that you
    lack is putting your client’s hot hand on the
    plunger, because you instructed the customer,
    “Here is how you use the thing.”

    5, 2011), ECF No. 273 at 5:12-20. Accordingly, the court
    denied Bodum’s motion to clarify.
    The district court subsequently granted Meyer’s mo-
    tion for summary judgment that Bodum’s sale of the
    Version 2 frothers infringe the claims of the ’122 Patent,
    finding that: (1) Bodum must have tested its products
    before putting them on the market; and (2) ”[t]hough
    Meyer does not provide evidence of specific instances of
    direct infringement by Bodum’s customers, such proof is
    not required because . . . Version 2 ‘necessarily infringes’
    the patented method when operated as directed.” Sum-

    motion to alter the court’s prior summary judgment
    decisions, reiterating that Bodum’s products have one
    goal – to froth milk – and that Bodum cannot avoid liabil-
    ity by claiming that it does not use the device.

    mary judgment of infringement requires two steps:
    (1) claim construction; and (2) comparison of the properly
    construed claims to the accused product or process.

    566 F.3d 1282
    , 1288 (Fed.

    Where, as here, the asserted patent claims are

    not infringe the patent. i4i Ltd. P’ship v. Microsoft Corp.,
    
    598 F.3d 831
    , 850 (Fed. Cir. 2010) (citation omitted).
    Instead, direct infringement of a method claim requires a
    showing that every step of the claimed method has been
    practiced. Lucent Techs., Inc. v. Gateway, Inc., 
    580 F.3d 1301
    , 1317 (Fed. Cir. 2009).
    Under 
    35 U.S.C. § 271
    (b), a party who “actively in-
    duces infringement of a patent shall be liable as an in-
    fringer.” To prevail on an inducement claim, a patentee
    must establish that: (1) there has been direct infringe-
    ment; (2) the defendant, with knowledge of the patent,
    actively and knowingly aided and abetted such direct
    infringement. DSU Med. Corp. v. JMS Co., 
    471 F.3d 1293
    , 1305 (Fed. Cir. 2006) (en banc).       It is well-
    established that a finding of direct infringement is a
    prerequisite to a finding of inducement. Ricoh Co. v.
    Quanta Computer Inc., 
    550 F.3d 1325
    , 1341 (Fed. Cir.
    2008) (“[A] finding of inducement requires a threshold
    finding of direct infringement.”).
    On appeal, Bodum argues both that the district court
    assumed that acts of direct infringement occurred when
    there was no evidence in the record that they did and that
    the district court misapplied the law with respect to
    inducement in the context of method claims. According to
    19                             MEYER INTELL PROP   v. BODUM
    Bodum, because there was no evidence that any single
    party, including Bodum itself, actually performed each
    step of the asserted method claims, there can be no find-
    ing of direct infringement or inducement. Since this
    court’s decision in Akamai has been vacated pending en
    banc review, Bodum relies upon our decision in BMC
    Resources, Inc. v. Paymentech, L.P., 
    498 F.3d 1373
     (Fed.
    Cir. 2007) to support its argument.
    Meyer responds that: (1) as the district court held,
    Bodum waived its direct infringement argument with
    respect to Version 1; and (2) Bodum’s own witnesses
    admitted actual use of Bodum’s Version 1 and Version 2
    frothers during testing of the frothers. Notably, Meyer
    abandons its argument that a finding of infringement can
    be premised on the acts of its own expert during the
    course of litigation. Meyer neither cites nor discusses
    BMC in its brief to this court. 4
    For the reasons discussed below, we conclude that the
    district court erred in granting summary judgment of
    infringement with respect to both the Version 1 and
    Version 2 frothers because the record was inadequate to
    support such a conclusion as a matter of law. In reaching
    this conclusion, we find no reason to discuss or apply this
    court’s case law on divided infringement or to await its
    clarification en banc because we find that, properly con-
    4  On appeal, Bodum separately argues that its Ver-
    sion 2 frother cannot infringe because it does not have a
    spring biasing screen, as is required in Claims 19 and 23
    of the ’122 Patent. In response, Meyer argues that:
    (1) there is no spring limitation in Claims 19 or 23 of the
    ’122 Patent; and (2) the O-ring present in the Version 2
    frother is the equivalent of the spring specified in certain
    claims of the patents-in-suit. Appellees’ Br. 54-55. Be-
    cause we find issues of material fact with respect to direct
    infringement and inducement, we need not address
    Bodum’s additional arguments at this stage.
    MEYER INTELL PROP   v. BODUM                              20
    strued, each step of the method claims could be performed
    by a single user.
    1. Waiver
    First, we disagree with the district court’s finding that
    Bodum conceded direct infringement as to its Version 1
    frother. In its initial motion seeking summary judgment,
    Meyer’s sole argument with respect to direct infringement
    was that “literal and direct infringement exists by one,
    such as Meyer’s expert, Albert Karvelis, when practicing
    the method prescribed in Bodum’s instructions while
    using Bodum’s accused milk frothers.” Mem. in Supp. of
    Pls.’ Mot. for Partial Summ. J., Meyer Intellectual Props.
    Ltd. v. Bodum, Inc., No. 06-cv-6329, (N.D. Ill. Sept. 2,
    2008), ECF No. 90 at 8 (emphasis added). Meyer did not
    argue that anyone other than Mr. Karvelis practiced each
    step of the claimed method by using Bodum’s Version 1
    frother. Nor did Meyer offer evidence of or even argue
    that anyone at Bodum ever practiced every step of the
    method claim or that there was any known customer who
    did so.
    In response, Bodum both rejected the notion that Mr.
    Karvelis’ actions could constitute acts of infringement and
    argued that no single person or entity – not even Mr.
    Karvelis – could perform all steps of the method claim
    because Bodum itself practiced the “providing a con-
    tainer” step, and only that step. Recognizing that induced
    infringement requires proof of both direct infringement
    and that the alleged inducer knowingly aided and abetted
    that direct infringement, Bodum argued that:
    Meyer’s allegation of direct infringement is im-
    proper for at least the reason that, as drafted, no
    one party can directly infringe any of the inde-
    pendent method claims. Only Bodum performs
    the first step of each independent claim, the step
    21                             MEYER INTELL PROP   v. BODUM
    of providing a container or housing associated
    with its Accused Products. The remaining steps
    are each performed only by Bodum’s customers.
    As a result there is no direct infringement and
    consequently, no inducement.

    Bodum, Inc., No. 06-cv-6329, (N.D. Ill. Nov. 21, 2008),
    ECF No. 99 at 13. Given this language, we find that the
    district court erred in concluding that Bodum “raise[d] no
    defense to the argument that its products directly in-
    fringed the Meyer Patents.” Summary Judgment Version
    1, 
    597 F. Supp. 2d at 794
    . In these circumstances, we
    agree with Bodum that no waiver occurred.
    2. Claim Construction
    Resolution of the parties’ dispute turns, in large part,
    on the construction of the term “providing” as it is used in
    the patent claims. Claim construction is an issue of law
    subject to de novo review on appeal. See Cybor Corp. v.
    FAS Techs., Inc., 
    138 F.3d 1448
    , 1456 (Fed. Cir. 1998) (en
    banc).
    To ascertain the scope and meaning of the asserted
    claims, we look to the claim language, the specification,
    the prosecution history, and any relevant extrinsic evi-
    dence. Phillips v. AWH Corp., 
    415 F.3d 1303
    , 1315-17
    (Fed. Cir. 2005) (en banc). As a general rule, a claim term
    is given the plain and ordinary meaning as understood by
    a person of ordinary skill in the art at the time of inven-
    tion. 
    Id. at 1312-13
    .
    Although claim construction begins with the language
    of the claims themselves, the claims “must be read in view
    of the specification, of which they are a part.” Markman
    v. Westview Instruments, Inc., 
    52 F.3d 967
    , 979 (Fed. Cir.
    1995) (en banc). Indeed, the specification “is the single
    MEYER INTELL PROP   v. BODUM                             22
    best guide to the meaning of a disputed term” and it “acts
    as a dictionary when it expressly defines terms used in
    the claims or when it defines terms by implication.”
    Phillips, 415 F.3d at 1321 (quoting Vitronics Corp. v.
    Conceptronic, Inc., 
    90 F.3d 1576
    , 1582 (Fed. Cir. 1996)).
    We have also recognized that dictionaries “are often
    useful to assist in understanding the commonly under-
    stood meaning of words.” Id. at 1322. As such, we have
    held that judges are free to rely on dictionary definitions
    when construing claims, “so long as the dictionary defini-
    tion does not contradict any definition found in or ascer-
    tained by a reading of the patent documents.” Id. at 1322-
    23 (quoting Vitronics, 
    90 F.3d at
    1584 n.6).
    As noted, representative Claim 1 of the ’087 Patent
    generally discloses four steps: (1) providing a container
    with a 2:1 height to diameter ratio; (2) pouring milk into
    the container; (3) introducing a plunger; and (4) pumping
    the plunger to aerate the liquid. The parties’ summary
    judgment arguments, and the district court’s ruling
    thereon, focused on the first step: “providing a container.”
    It is undisputed that the patents-in-suit do not explicitly
    define the term “providing.”
    During claim construction, neither party asked the
    court to construe the term “providing.” Although claim
    construction is a question of law, we are generally hesi-
    tant to construe claim terms for the first time on appeal.
    Wavetronix v. EIS Elec. Integrated Sys., 
    573 F.3d 1343
    ,
    1355 (Fed. Cir. 2009). Under the circumstances of this
    case, however, we find it appropriate to do so. While the
    parties specifically addressed the meaning and scope of
    this term in their summary judgment briefing to the
    district court, the court did not formally construe the
    claim term because it found no reason to do so. Instead,
    the court found that Bodum could be liable for induced
    infringement even if it, and only it, performed the provid-
    23                             MEYER INTELL PROP   v. BODUM
    ing step because Bodum thereafter directed its customers
    on how to perform the remaining steps of the claim.
    Because the record is sufficiently developed to enable us
    to construe the term, and because the parties’ debate
    really focuses on the scope, rather than the meaning of
    the claim terms, we choose to address the question the
    trial court sidestepped.
    In opposition to Meyer’s motion for summary judg-
    ment, Bodum supplied the following dictionary definition
    for the word “provide”: “1. To furnish; supply. 2. To make
    available; afford. 3. To set down as a stipulation. 4.
    Archaic: To make ready ahead of time; prepare.” Am.
    Heritage College Dictionary 1102 (3d ed. 2000). Bodum
    argued that, because it supplies, furnishes, and otherwise
    makes the accused products available for sale, it is the
    only party that can carry out the providing step. In its
    reply, Meyer agreed that providing should be given its
    common ordinary meaning, but argued that “there is no
    limitation in the claims on who does the ‘providing,’ and
    none exists. Bodum can do the providing or the end user
    completing the claimed method steps can do the provid-
    ing. In either event, direct infringement occurs.” Reply in
    Supp. of Pls.’ Mot. for Partial Summ. J., Meyer Intellectual
    Props. Ltd. v. Bodum, Inc., No. 06-cv-6329, (N.D. Ill. Dec.
    5, 2008), ECF No. 105 at 13.
    In its decision granting summary judgment as to
    Bodum’s Version 1 frothers, the district court acknowl-
    edged Bodum’s proffered dictionary definition and its
    argument that, because an end user “cannot ‘provide’ the
    container as called for by the claims,” Bodum does not
    induce infringement. Summary Judgment Version 1, 
    597 F. Supp. 2d at 798
    . Rather than analyze the scope of the
    term “providing,” however, the district court found that,
    even under Bodum’s definition, Bodum’s argument fails
    because “it impermissibly distorts the fundamental con-
    MEYER INTELL PROP   v. BODUM                            24
    cept of patent infringement.” 
    Id.
     Specifically, the court
    held that, “[w]hen any end user ‘uses’ a Bodum milk
    frother – a container – that has been ‘provided’ by Bodum,
    and in doing so follows Bodum’s instructions detailing the
    steps to be taken in such use of the frother . . . it thus
    directly infringes the Meyer Patents.” 
    Id. at 798-99
    .
    Notably, however, nothing in the district court’s decision
    suggests that Bodum is the only party that can “provide”
    the container for use.
    After careful review of the intrinsic evidence, we find
    that nothing in the claim language or the patent specifica-
    tion limits the “providing” step to a specific party. Under
    Bodum’s proffered dictionary definition, it is clear that
    Bodum “furnishes” or “supplies” the container by manu-
    facturing and selling its milk frothers. It is also clear
    under that same definition, however, that anyone who
    takes a Bodum frother from the kitchen cabinet and
    places it on the counter before filling it with milk can
    satisfy the “providing” step. That person has undoubtedly
    made the container available for use and prepared it for
    frothing. Accordingly, we construe the term “providing” to
    mean “furnishing, supplying, making available, or prepar-
    ing” and find that anyone – Bodum or the end user of its
    products – can satisfy the providing step. Given this
    construction, we find that the claims at issue here are
    drawn to actions that can be performed by a single party.
    3. Direct Infringement
    Having concluded that a single party is capable of in-
    fringing the patents-in-suit, we move to the parties’
    arguments regarding infringement. We turn first to the
    issue of direct infringement. As noted, in its motion for
    summary judgment with respect to Bodum’s Version 1
    frother, Meyer’s only evidence of direct infringement was
    the activities of Meyer’s own expert. On appeal, Bodum
    25                             MEYER INTELL PROP   v. BODUM
    argues that Meyer did not introduce any evidence that
    either Bodum or its customers used the claimed method.
    Meyer responds that Bodum’s witnesses conceded use.
    Again, Meyer does not argue that there was evidence of
    customer infringement. For the reasons explained below,
    we agree with Bodum that the district court’s judgments
    of infringement as to both the Version 1 and Version 2
    frothers suffer from the same deficiency: there was no
    evidence of direct infringement in the record.
    As to the Version 1 frothers, the district court relied
    only on its conclusion that Bodum had conceded direct
    infringement, though the court never explained to whom
    that concession pertained. Because we find that Bodum
    made no such concession, Meyer points to no other evi-
    dence of direct infringement as to the Version 1 frothers,
    and we find none in the underlying summary judgment
    papers, we conclude that the trial court erred in finding
    direct infringement as a matter of law as to those froth-
    ers.
    In its decision granting Meyer summary judgment
    with respect to the Version 2 frothers, the district court
    rejected Bodum’s argument that Meyer failed to prove
    direct infringement. Specifically, the court found it unbe-
    lievable that “an established company such as Bodum
    would have placed Version 2 and later Version 3 on the
    market for public sale, and would have kept those prod-
    ucts on the market for substantial periods of time, with-
    out having first confirmed for itself that each product
    would perform its allotted task . . . .” Summary Judgment
    Version 2, 
    674 F. Supp. 2d at 1018
    . In other words, the
    court assumed that Bodum must have tested its products.
    Given this assumption, the court concluded that Bodum’s
    use of the ’122 Patent method “has been established as a
    matter of law.” 
    Id.
    MEYER INTELL PROP   v. BODUM                             26
    We find it troubling that the district court based its
    direct infringement analysis on what it assumed hap-
    pened, rather than on actual evidence of record. This
    assumption contradicts our well-established law that a
    patentee must prove infringement by a preponderance of
    the evidence. See Siemens Med. Solutions USA, Inc. v.
    Saint-Gobain Ceramics & Plastics, Inc., 
    637 F.3d 1269
    ,
    1279 (Fed. Cir. 2011) (“Patent infringement, whether
    literal or by equivalence, is an issue of fact, which the
    patentee must prove by a preponderance of the evi-
    dence.”). And, by assuming testing without any evidence
    in the record, the court improperly drew an inference in
    favor of Meyer and against Bodum. Because factual
    inferences must be drawn in favor of the nonmoving party
    on summary judgment, we find that the district court’s
    decision cannot stand. See IMS Tech., Inc. v. Haas Auto-
    mation, Inc., 
    206 F.3d 1422
    , 1429 (Fed. Cir. 2000) (noting
    that, on summary judgment, “[w]e view the evidence in a
    light most favorable to the non-movant, and draw all
    reasonable inferences in its favor”).
    For the first time on appeal, Meyer cites to deposition
    testimony from Bodum’s President, Thomas Perez, as
    evidence that Bodum used the claimed method in testing
    and developing its frothers. Specifically, Meyer points to
    Perez’s testimony that Bodum’s design team always tests
    each of its products. Bodum argues that Meyer’s reliance
    on this testimony is misplaced because the portions cited
    were neither submitted with the motions for summary
    judgment nor introduced at trial. In addition, Bodum
    points to the testimony of Jorgen Bodum, Bodum’s Chief
    Executive Officer (hereinafter referred to as “Jorgen”),
    that he conducts product development with his design
    team which consists of five people in Hong Kong and
    fifteen people in Switzerland. In other words, there is no
    27                             MEYER INTELL PROP   v. BODUM
    evidence that Bodum used or tested its milk frother
    products in the United States.
    We agree with Bodum that Meyer cannot for the first
    time on appeal introduce deposition testimony that was
    not before the district court when it was deciding the
    motions for summary judgment. And, given Jorgen’s trial
    testimony that Bodum’s product development team is
    located in Hong Kong and Switzerland, Meyer has not –
    at this stage – shown any instances of direct infringement
    in the United States. Because direct infringement of a
    method claim requires that each of the claimed steps are
    performed within the United States, the evidence of
    record is insufficient as a matter of law to support the
    court’s decision granting summary judgment. See NTP,
    Inc. v. Research in Motion, Ltd., 
    418 F.3d 1282
    , 1318 (Fed.
    Cir. 2005) (“We therefore hold that a process cannot be
    used ‘within’ the United States as required by section
    271(a) unless each of the steps is performed within this
    country.”).
    Based on the foregoing, we find that Meyer failed to
    point to specific instances of direct infringement and
    failed to offer any evidence that someone at Bodum used
    its Version 1 and Version 2 frothers. Accordingly, we find
    that there are genuine issues of material fact as to
    whether anyone at Bodum practiced each step of the
    asserted method claims.
    We now turn to the trial court’s conclusion that
    Bodum intended that its customers would use the frothers
    to produce froth liquid and that the act of frothing there-
    after would constitute direct infringement. While it may
    be true that Bodum’s customers may be characterized as
    direct infringers under our now-controlling construction of
    the providing step, Meyer never argued at the summary
    judgment stage that they were, and it does not make that
    MEYER INTELL PROP   v. BODUM                            28
    argument here. Indeed, Meyer presented no evidence in
    support of its motion for summary judgment regarding
    either product sales or customer use; it relied only on Mr.
    Karvelis’ testing of the product. Judgment as a matter of
    law on such a sparse record is simply not appropriate.
    Because we conclude that genuine issues of material
    fact remain, we reverse the district court’s grant of sum-
    mary judgment with respect to Bodum’s Version 1 and
    Version 2 frothers and remand for further consideration
    in light of our construction of the term “providing.”
    B. Evidentiary Rulings
    We turn next to Bodum’s challenges to the district
    court’s evidentiary rulings. On appeal, Bodum argues
    that the district court improperly: (1) excluded Bodum’s
    primary prior art, including Bodum’s 3-Cup French Press;
    (2) barred Bodum’s expert witness – Anders – from testi-
    fying that the asserted patents were invalid for obvious-
    ness; and (3) precluded Jorgen from testifying about the
    Bodum 3-Cup French Press. Given these rulings, Bodum
    argues that it was stripped of its ability to present its
    obviousness defense at trial.
    We review the district court’s decision to exclude evi-
    dence under the law of the relevant regional circuit.
    Research Corp. Techs. v. Microsoft Corp., 
    536 F.3d 1247
    ,
    1255 (Fed. Cir. 2008) (“The Federal Circuit applies its
    own law with respect to issues of substantive patent law
    and certain procedural issues pertaining to patent law,
    but applies the law of our sister circuits to non-patent
    issues.”) (citation omitted). The Seventh Circuit – the
    pertinent regional circuit in this case – reviews eviden-
    tiary rulings for an abuse of discretion. Von Der Ruhr v.
    Immtech Int’l, Inc., 
    570 F.3d 858
    , 862 (7th Cir. 2009)
    (noting that “decisions regarding the admission and
    29                             MEYER INTELL PROP   v. BODUM
    exclusion of evidence are peculiarly within the compe-
    tence of the district court”) (citation omitted).
    In the Seventh Circuit, appellate review of eviden-
    tiary rulings is limited to determining “whether an ‘error
    in either the admission or the exclusion of evidence’ was
    made which affected ‘the substantial rights’ of the plain-
    tiffs.” Nachtsheim v. Beech Aircraft Corp., 
    847 F.2d 1261
    ,
    1266 (7th Cir. 1988) (quoting Fed. R. Civ. P. 61). Gener-
    ally speaking, “the test of whether a substantial right of a
    party has been affected is whether the error in question
    affected the outcome of the case.” 2 Jack B. Weinstein &
    Margaret A. Berger, Weinstein’s Federal Evidence
    § 103.41[2] (Joseph M. McLaughlin, ed., Matthew Bender
    2d ed. 2011).
    More recently, the Seventh Circuit held that “[n]o er-
    ror in either the admission or exclusion of evidence is
    ground[s] for . . . vacating, modifying, or otherwise dis-
    turbing a judgment or order, unless refusal to take such
    action appears to the court inconsistent with substantial
    justice.” Thompson v. City of Chicago, 
    472 F.3d 444
    , 455
    (7th Cir. 2006) (quoting Goodman v. Illinois Dept. of Fin.
    & Prof. Reg., 
    430 F.3d 432
    , 439 (7th Cir. 2005)). The
    court recognized that “[e]ven an erroneous evidentiary
    ruling can be deemed harmless if the record indicates that
    the same judgment would have been rendered regardless
    of the error.” 
    Id.
     (quoting Goodman, 
    430 F.3d at 439
    ).
    Accordingly, Bodum must show both that the district
    court erred in excluding evidence and that the exclusion
    prejudiced its substantial rights.
    For the reasons explained below, we find that the dis-
    trict court abused its discretion in granting Meyer’s
    motions in limine and that these evidentiary errors were
    prejudicial because they prevented Bodum from present-
    ing its obviousness defense. Accordingly, we vacate and
    MEYER INTELL PROP   v. BODUM                              30
    remand for a new trial to address whether the asserted
    claims are invalid as obvious.
    1. Prior Art
    As previously noted, the district court granted
    Meyer’s motions in limine and limited the universe of
    prior art on which Bodum could rely. In particular, the
    court found that: (1) Bodum’s discovery responses “identi-
    fied a not particularly extensive group of [prior art]
    items”; and (2) Anders reviewed the fifty-six items listed
    in Part A of his report but then “focused solely on just two
    of those many items as the actual predicates for his stated
    conclusions.” Meyer v. Bodum, 
    2010 U.S. Dist. LEXIS 56168
    , at *2-4. In its proposed list of exhibits in the Final
    Pretrial Order, however, Bodum included what the court
    characterized as a “laundry list” of prior art exhibits.
    Because it found that Bodum’s discovery responses and
    expert report narrowed the relevant prior art, the court
    found that Bodum could rely only on two items of prior art
    at trial: the Reissue Ghidini Patent and the Bodum
    French 3-Cup French Press. As discussed below, more-
    over, at trial, the court further limited Bodum’s introduc-
    tion of evidence to exclude the Bodum 3-Cup French
    Press.
    Bodum explains that, prior to trial, its invalidity posi-
    tion was that each claim of the ’087 and ’122 Patents is
    made obvious by a combination of the Bodum 3-Cup
    French Press and the Reissue Ghidini Patent. 5 According
    5     Bodum was not allowed to use the Ghidini Reis-
    sue Patent as prior art because it did not pre-date the
    patents-in-suit. It was, however, permitted to use the
    original Ghidini patent – United States Patent No.
    5,580,169 (“the ’169 Patent”) – which predated the as-
    serted patents, and both Ghidini Patents were admitted
    at trial.
    31                              MEYER INTELL PROP   v. BODUM
    to Bodum, its 3-Cup French Press “teaches all of the
    elements required in the ’087 and ’122 Patents with the
    exception of using a coffee press as a frother,” and the
    Reissue Ghidini Patent teaches a method for frothing
    milk in a container with a plunger assembly. Appellant’s
    Br. 17. Bodum contends that, had it been permitted to
    offer the wrongfully excluded exhibits, “it would have
    been clear to the jury that the combination of at least the
    Bodum 3-Cup French Press and the Reissue Ghidini
    Patent show all of the features of the claimed invention.”
    
    Id. at 20
    .
    On appeal, Bodum argues that the district court erred
    when it excluded its 3-Cup French Press as well as the
    other prior art that was disclosed both during discovery
    and in Anders’ report. In response, Meyer argues that
    Bodum’s prior art was not properly disclosed and that the
    relevant scope of prior art was narrowed by Bodum’s own
    expert. We disagree with Meyer.
    We turn first to the district court’s exclusion of prior
    art that Bodum disclosed in its interrogatory responses.
    During discovery, Meyer asked Bodum to identify and
    explain the factual bases for Bodum’s claim that the
    patents at issue were invalid. In its Second Supplemental
    Answers to Interrogatories 2 and 3, Bodum identified,
    among other things, its prior Chambord French Press
    products, the Insta-Brewer French Press coffee maker,
    which “includes a container that is at least twice as tall as
    it is wide and includes a plunger structure,” advertise-
    ments for the Insta-Brewer showing that it was available
    for sale in 1965, a still frame image from the movie “The
    Ipcress File” which showed use of the Insta-Brewer in
    1965, the file history of the Reissue Ghidini Patent, and
    catalogs showing that the Bodum 3-Cup French Press was
    offered for sale in the United States prior to 1995. In-
    deed, at oral argument, counsel for Meyer conceded that,
    MEYER INTELL PROP   v. BODUM                               32
    at a minimum, the following prior art was disclosed in
    Bodum’s interrogatory responses: “certainly the 3 cup was
    in there, the Ghidini Patent was in there, there was also,
    I think, a digital image from a movie, there was also a
    catalog.” See Oral Argument at 17:45, available at
    http://www.cafc.uscourts.gov/oral-argument-
    recordings/2011-1329/all.
    Turning to the prior art discussed in Anders’ report,
    careful review of Part C reveals that Anders’ opinion on
    obviousness was not, as the district court found, limited to
    just two pieces of prior art. Indeed, Part C of the report
    specifically references: (1) the Ghidini Reissue Patent;
    (2) the Bodum French Press; and (3) the “drawing of a
    Bodum French press container dated 6.2.84 with Bates
    number B01781 shows a container having a height that is
    two times the diameter.” J.A. 4378. The district court
    trifurcated Anders’ report and found that the list of
    documents included in Part A were not relied upon with
    respect to obviousness because they were not substan-
    tively discussed in Part C. The fact remains, however,
    that those references in Part A – including the Bodum
    Chambord 3-cup coffee maker and catalog pages of Bodum
    products – were included in the expert report and were,
    thus, provided to Meyer.
    Even assuming we agree with the district court that
    Anders relied only on the specific prior art listed in Part C
    for his obviousness opinion, the district court still erred in
    using the Anders’ report to limit Bodum’s ability to pre-
    sent, through other witnesses at trial, prior art that was
    previously disclosed during discovery. If anything, the
    scope and content of Anders’ report should operate only to
    limit his testimony at trial – not the testimony of any
    other witnesses.
    33                             MEYER INTELL PROP   v. BODUM
    Meyer concedes that it received Bodum’s interroga-
    tory responses, and thus was on notice of Bodum’s intent
    to use the prior art included therein. 6 Meyer nonetheless
    contends the court was correct to prohibit reliance on that
    art at trial, however. During oral argument, counsel for
    Meyer explained that, although it knew about the prior
    art in Bodum’s discovery responses, “there was a further
    narrowing as to what the case was going to be . . . in the
    expert report.” Oral Argument at 19:40. Counsel ex-
    plained that the district court ultimately precluded
    Bodum’s expert from testifying as to obviousness, and
    that the court “felt that this [other prior art disclosed
    during discovery] should not come in without expert
    testimony coming in with it because it was just going to
    lead to speculation from the jury.” 
    Id. at 23:54
    .
    Where, as here, the technology involved is simple, we
    can think of no explanation for excluding prior art that
    was disclosed in interrogatory responses but was not
    relied upon in an expert report. As this court recently
    reiterated, “[t]here is no invariable requirement that a
    prior art reference be accompanied by expert testimony.”
    In re Brimonidine Patent Litig., 
    643 F.3d 1366
    , 1376 (Fed.
    Cir. 2011) (citation omitted). It is well-established, more-
    6  In its decision, the district court stated that
    Bodum never supplemented its initial discovery responses
    and that “Bodum’s initial response has set the outer
    boundaries of the potential ‘prior art’ universe.” Meyer,
    
    2010 U.S. Dist. LEXIS 56168
    , at *2. To the contrary,
    however, Meyer admits in its briefing in support of its
    motion in limine that it received, and was relying upon,
    Bodum’s Second Supplemental Answers to Plaintiffs’
    Interrogatories Nos. 2 and 3 dated March 18, 2009. Mem.

    erred in finding that Bodum did not supplement its dis-
    covery responses.
    MEYER INTELL PROP   v. BODUM                             34

    standable, expert testimony is not required. Wyers v.

    ,

    testimony will not be necessary because the technology
    will be ‘easily understandable without the need for expert
    explanatory testimony.’” (citation omitted)).
    The district court’s evidentiary errors improperly nar-
    rowed the scope of prior art that Bodum could introduce
    at trial and prevented Bodum from using its primary
    piece of prior art – the Bodum 3-Cup French Press.
    Because we find that the court’s erroneous evidentiary
    rulings prejudiced Bodum’s ability to present its invalid-
    ity defense, we vacate and remand for a new trial on
    obviousness.
    2. Expert Testimony
    Bodum next argues that the district court erred in
    granting Meyer’s motion to exclude Anders’ testimony. In
    response, Meyer contends that Anders offered a conclu-
    sory opinion with no explanation or support and that the
    district court properly excluded his testimony under Rule
    26(a) of the Federal Rules of Civil Procedure. 7
    Rule 26(a) requires disclosure of a written expert re-
    port that contains “a complete statement of all opinions
    7    On appeal, Meyer also argues that the district
    court relied on Rule 702 of the Federal Rules of Evidence
    in excluding Anders, and that this court can only reverse
    the district court’s ruling if it is “manifestly erroneous.”
    Appellees’ Br. 34-35. Notably, however, Meyer moved to
    bar Anders’ testimony solely under Rule 26 – not Rule
    702. And, although the district court’s decision briefly
    mentions Rule 702, the court focuses its analysis on Rule
    26(a)(2)(B)(i).
    35                               MEYER INTELL PROP   v. BODUM
    the witness will express and the basis and reasons for
    them.” Fed. R. Civ. P. 26(a)(2)(B)(i). The purpose of this
    rule is “to convey the substance of the expert’s opinion . . .
    so that the opponent will be ready to rebut, to cross-
    examine, and to offer a competing expert if necessary.”
    Walsh v. Chez, 
    583 F.3d 990
    , 994 (7th Cir. 2009).
    In the patent context, an expert report that merely
    lists a number of prior art references and concludes that
    one skilled in the art would find the claims obvious is
    deficient under Rule 26. Innogenetics, N.V. v. Abbott
    Labs., 
    512 F.3d 1363
    , 1373 (Fed. Cir. 2008). In Innogenet-
    ics, for example, we found that the expert’s report failed to
    “state how or why a person ordinarily skilled in the art
    would have found the claims . . . obvious in light of some
    combination of those particular references.” 
    Id.
     Given
    this deficiency, we affirmed the district court’s decision
    precluding the expert’s vague and conclusory testimony
    regarding obviousness. 
    Id. at 1374
    .
    Here, the district court found that Anders’ report
    failed to comply with Rule 26, and that Anders advanced
    “his opinion as a mere ipse dixit . . . .” Meyer, 
    715 F. Supp. 2d at 830
    . In reaching this decision, the district
    court relied heavily on Innogenetics, suggesting that it
    “might well have been written for this case.” 
    Id.
     We
    disagree. Unlike the situation in Innogenetics, here,
    Anders’ report does more than merely list prior art refer-
    ences and provide a conclusion of obviousness.
    First, Anders defined a person of ordinary skill in the
    art as someone who has “an undergraduate degree in
    industrial design or mechanical engineering, with one to
    three years experience” or, in the alternative, “a person
    without a degree but with five or more years of practical
    experience in the consumer products or housewares
    industry.” Expert Report of Robert John Anders, Meyer
    MEYER INTELL PROP   v. BODUM                             36
    Intellectual Props. Ltd. v. Bodum, Inc., No. 06-cv-6329
    (N.D. Ill. Nov. 16, 2010), ECF No. 217 at 27. Anders then
    provided detailed claim charts comparing the asserted
    claims to the relevant prior art. As previously noted, the
    claim charts in Part C of Anders’ report identify three
    items of prior art: (1) the Ghidini Reissue Patent; (2) the
    Bodum French Press; and (3) the “drawing of a Bodum
    French press container dated 6.2.84” with a height that is
    two times the diameter.
    In his report, Anders explained that “a designer of or-
    dinary skill in the art at the time of the claimed invention
    would have been familiar with the methods for aerating
    milk based liquids as well as with the structure of the
    French press apparatus, and thus the combination would
    have been obvious to said designer.” Id. at 29. In Anders’
    opinion, all Brady did was “copy an old apparatus which
    was also known to be capable of frothing milk . . . and
    fabricate a ‘method’ that was in fact also old and well
    known and detailed in the prior art patents.” Id. Given
    these circumstances, Anders concluded that the patents-
    in-suit are invalid for obviousness.
    Careful review of Anders’ report reveals that it con-
    tains a sufficiently detailed statement of his opinions and
    the bases for his conclusions. This is particularly true
    given that the technology involved in this case – using a
    plunger to froth milk in a container – is not complex.
    According to Anders, the patents-in-suit are obvious
    because one skilled in the art would have been motivated
    based on familiarity with the prior art to combine the
    known method for aerating milk in a frother with the
    structure of a French press. In other words, Anders
    invoked the common sense of one skilled in the art as
    evidence of motivation to combine prior art references.
    Given the technology involved, we find no fault in Anders’
    reliance on common sense in rendering his obviousness
    37                             MEYER INTELL PROP   v. BODUM
    opinion. Indeed, this court has specifically recognized
    that the common sense of one skilled in the art can play a
    role in the obviousness analysis. See Perfect Web Techs.,
    Inc. v. InfoUSA, Inc., 
    587 F.3d 1324
    , 1329 (Fed. Cir. 2009)
    (holding that “an analysis of obviousness . . . may include
    recourse to logic, judgment, and common sense available
    to the person of ordinary skill [which] do[es] not necessar-
    ily require explication in any reference or expert opin-
    ion”).
    Because the technology involved is simple and com-
    mon sense would motivate one of skill in the art to make
    the combination, Anders’ report is sufficiently detailed.
    Accordingly, we conclude that the district court abused its
    discretion when it excluded Anders’ testimony. We fur-
    ther find that the exclusion of Anders’ testimony was not
    harmless because it impaired Bodum’s ability to present
    its obviousness defense. And, as Bodum points out in its
    brief, while Meyer’s expert was permitted to testify as to
    why the patent was not obvious, the exclusion of Anders’
    testimony made it look as though Bodum had no rebuttal.
    3. Lay Testimony
    Prior to trial, the district court ruled that Bodum
    could not introduce testimony from lay witnesses to
    expand the scope of prior art on which its expert relied.
    Although Bodum intended to have Jorgen introduce and
    authenticate a Bodum 3-Cup French Press at trial, the
    district court ultimately prohibited any such testimony on
    grounds that it was an impermissible attempt to “back-
    door” the court’s prior orders excluding prior art.
    On appeal, Bodum argues that the district court erred
    in refusing to let Jorgen testify to issues that were within
    his personal knowledge, including the Bodum 3-Cup
    French Press and catalogs and drawings depicting the
    features of that device prior to the filing of the applica-
    MEYER INTELL PROP   v. BODUM                              38
    tions that resulted in the patents-in-suit. In response,
    Meyer argues that the district court acted within its
    discretion in refusing to let Jorgen testify be-
    cause uncorroborated testimony from interested parties is
    insufficient to invalidate a patent under the so-called
    Barbed Wire doctrine.
    The     “Barbed   Wire    doctrine”   provides   that
    “[c]orroboration is required of any witness whose testi-
    mony alone is asserted to invalidate a patent.” TypeRight

    invalidating patents on the basis of mere testimonial
    evidence absent other evidence that corroborates that
    testimony.”) (citation omitted). We have explained that
    this requirement “arose out of a concern that inventors
    testifying in patent infringement cases would be tempted
    to remember facts favorable to their case by the lure of
    protecting their patent or defeating another’s patent.”

    can be “unsatisfactory” given “the forgetfulness of wit-
    nesses, their liability to mistakes, their proneness to
    recollect things as the party calling them would have
    them recollect them, aside from the temptation to actual
    perjury . . . .”).
    Bodum argues that the Barbed Wire doctrine does not
    apply here because: (1) the district court did not rely on it
    in excluding the testimony; and (2) Bodum is not relying
    on oral testimony alone to prove invalidity. We agree
    with Bodum on both points.
    39                              MEYER INTELL PROP   v. BODUM
    First, as noted, the district court excluded Jorgen’s
    testimony on grounds that its proffer was an attempt to
    “backdoor” the judge’s prior ruling excluding Anders’
    expert testimony. Meyer, 
    2010 U.S. Dist. LEXIS 107169
    ,
    at *3. Nowhere in that order did the court cite to or rely
    upon the Barbed Wire doctrine. When counsel for Meyer
    invoked the Barbed Wire doctrine on the record during
    trial, the court reiterated its earlier order limiting
    Bodum’s prior art and simply stated that: “whether it
    happens to be supported or not by the barbed wire theory,
    which I think tends to sort of, in a way, corroborate it, is
    really not the point. So I am not permitting it.” Tr. of
    Proceedings held on Nov. 10, 2010, Meyer Intellectual
    Props. Ltd. v. Bodum, Inc., No. 06-cv-6329 (N.D. Ill. Apr.
    29, 2011), ECF No. 267 at 459:13-460:17. Accordingly, the
    record reveals that the district court did not base its
    decision on the Barbed Wire doctrine.
    Second, Meyer’s reliance on the Barbed Wire doctrine
    is misplaced because Bodum did not seek to rely on uncor-
    roborated oral testimony to establish invalidity. Instead,
    Bodum proffered Jorgen to testify that the version of the
    Bodum 3-Cup French Press it sought to introduce into
    evidence was an accurate example of the product as it
    existed prior to the patents-in-suit. According to Bodum,
    Jorgen would have testified that the design of the Bodum
    3-Cup French Press has not changed in any material
    respect since 1982, and that it includes: (1) a carafe with a
    2:1 height to diameter ratio; and (2) a plunger mechanism
    almost identical to that disclosed in the patents-in-suit.
    To corroborate Jorgen’s testimony, Bodum intended to
    offer drawings of the carafe and pages from its catalogs –
    all of which predated the patents-in-suit. According to
    Bodum, the drawings and catalogs show that the Bodum
    3-Cup French Press has the dimensional requirements
    and plunger disclosed in the patents-in-suit, and that
    MEYER INTELL PROP   v. BODUM                             40
    those features were present in the model that pre-dated
    Meyer’s patents. Although Meyer convinced the district
    court that Bodum’s reliance on the catalogs and drawings
    was an attempt to establish those documents as prior art
    to get around the court’s prior orders limiting the scope of
    prior art admissible at trial, it is clear that Bodum was
    relying on those documents to corroborate Jorgen’s testi-
    mony – not as independent prior art. Given this corrobo-
    rating evidence, the Barbed Wire doctrine would not have
    barred Jorgen’s testimony.
    Finally, we agree with Bodum that, given the simplic-
    ity of the technology involved, the jury could have consid-
    ered the Bodum 3-Cup French Press, other documents
    disclosed during discovery, and lay testimony to reach its
    decision regarding obviousness. This is not a situation
    where Bodum sought to have a lay witness give his own
    opinion regarding invalidity. Indeed, as counsel for
    Bodum explained to the district court: “we are not asking
    them to give an opinion. Mr. Bodum is going to testify
    about facts. Was this [3-Cup French Press] on sale? Yes.
    Is it – was it sold in 1982? Yes.” Tr. of Proceedings held
    on Nov. 10, 2010, Meyer Intellectual Props. Ltd. v. Bodum,
    Inc., No. 06-cv-6329 (N.D. Ill. Apr. 29, 2011), ECF No. 267
    at 460:18-20. In these circumstances, we see no problem
    with having Bodum’s CEO of thirty-six years testify to
    factual matters within his personal knowledge where
    those facts are supported by corroborating documentation.
    Accordingly, we hold that the district court erred in
    granting Meyer’s motion in limine barring Jorgen Bodum
    from testifying as to the Bodum 3-Cup French Press and
    the related drawings and catalogs. This error – coupled
    with each of the district court’s evidentiary errors dis-
    cussed above – had the cumulative effect of preventing
    Bodum from presenting the substance of its obviousness
    defense. The district court’s exclusion of Bodum’s primary
    41                              MEYER INTELL PROP   v. BODUM
    exhibits and related testimony resulted in a one-sided
    trial and we find that the court’s errors were not harm-
    less. On remand, the court should permit Jorgen to
    testify as to those matters within his personal knowledge
    with the corroborating documentation Bodum has identi-
    fied and previously disclosed during discovery.
    C. Inequitable Conduct
    Prior to trial, the district court granted Meyer’s mo-
    tion in limine to bar Bodum from presenting evidence in
    support of its inequitable conduct defense. Specifically,
    the court found that Bodum “failed to meet the demand-
    ing requirements” to prove inequitable conduct. Meyer,
    
    2010 U.S. Dist. LEXIS 56168
    , at *9. Bodum filed a mo-
    tion asking the court to reconsider its decision. In that
    motion, Bodum argued that the court erred in transform-
    ing Meyer’s request to limit evidence into a motion for
    summary judgment of no inequitable conduct without
    giving Bodum a chance to introduce all evidence that
    would be relevant to the court’s decision. The court
    denied Bodum’s motion to reconsider in a minute entry on
    August 4, 2010, and Bodum was barred from presenting
    any evidence regarding inequitable conduct at trial.
    On appeal, Bodum argues that the district court erred
    by dismissing its affirmative defense of inequitable con-
    duct on a motion in limine. In response, Meyer argues
    that, even if the district court erred, that error was harm-
    less because there is no right to a jury trial on inequitable
    conduct.
    As previously noted, the exclusion of evidence on a
    motion in limine is an evidentiary ruling reviewed for an
    abuse of discretion. Mid-America Tablewares, Inc. v.
    Mogi Trading Co., 
    100 F.3d 1353
    , 1362 (7th Cir. 1996).
    The Seventh Circuit has held that a motion in limine is
    not the appropriate vehicle for weighing the sufficiency of
    MEYER INTELL PROP   v. BODUM                             42
    the evidence. Specifically, in Mid-America, the court
    stated that, while argument regarding the sufficiency of
    the evidence “might be a proper argument for summary
    judgment or for judgment as a matter of law, it is not a
    proper basis for a motion to exclude evidence prior to
    trial.” 
    Id. at 1362-63
     (affirming the district court’s deci-
    sion denying a motion in limine to exclude evidence of lost
    profits and noting that the “determination as to whether
    future profits were within the contemplation of the par-
    ties when contracting necessarily turns on the specific
    facts established at trial”).
    After careful review of the record, we conclude that
    the district court erred in addressing the sufficiency of
    Bodum’s inequitable conduct defense on an evidentiary
    motion. We agree with Bodum that the district court
    essentially converted Meyer’s motion in limine into a
    motion for summary judgment. In doing so, the court did
    not allow for full development of the evidence and de-
    prived Bodum of an opportunity to present all pertinent
    material to defend against the dismissal of its inequitable
    conduct defense. Although both parties argue the merits
    of Bodum’s inequitable conduct defense on appeal, we
    need not address those arguments at this stage. Because
    we conclude that it was procedurally improper for the
    court to dispose of Bodum’s inequitable conduct defense
    on a motion in limine, we reverse the court’s decision and
    remand for further proceedings.
    D. Willfulness
    The jury found in favor of Meyer on the issue of will-
    fulness. After the jury verdict, Bodum filed a renewed
    motion for JMOL that it did not willfully infringe the
    patents-in-suit. On March 14, 2011, the district court
    denied Bodum’s motion in an oral ruling on the record
    and entered a minute entry to that effect. The court later
    43                               MEYER INTELL PROP   v. BODUM
    granted Meyer’s motion to enhance damages and award
    Meyer its attorney fees, stating that: (1) ”the jury’s find-
    ing of willfulness implies that Bodum was aware of
    Meyer’s products and, as already indicated, Bodum copied
    those products in every relevant way”; and (2) there was
    “serious trial misconduct on Bodum’s part” including that
    “Bodum moved to allow their lay witnesses to testify
    about asserted prior art that this Court had previously
    excluded because those items had not been designated as
    relevant prior art by Bodum’s retained expert.” Decision
    Awarding Attorney Fees, 
    764 F. Supp. 2d at 1008-09
    .
    On appeal, Bodum argues both that the court erred in
    denying its motion for JMOL of no willful infringement,
    and that enhanced damages and attorney fees are not
    warranted. Given our decision to remand this case for a
    new trial to address infringement and invalidity, we
    vacate the jury’s verdict of willfulness and the district
    court’s decision denying Bodum JMOL that it did not
    willfully infringe the patents-in-suit. On remand, Bard
    Peripheral Vascular, Inc. v. W.L. Gore & Associates, Inc.,
    
    682 F.3d 1003
     (Fed. Cir. 2012), may be a helpful starting
    place for any future analysis of willfulness.
    Because we vacate the jury’s finding of willfulness, we
    also vacate the district court’s decision awarding en-
    hanced damages to Meyer. See i4i, 
    598 F.3d at 858
     (“A
    finding of willful infringement is a prerequisite to the
    award of enhanced damages.”). With respect to attorney
    fees, the district court based its decision, at least in part,
    on the willfulness verdict and Bodum’s alleged litigation
    misconduct in its presentation of evidence. Because we
    have herein reversed the district court’s evidentiary
    rulings and vacated the willfulness verdict, we also vacate
    the award of attorney fees.
    MEYER INTELL PROP   v. BODUM                            44
    CONCLUSION
    For the foregoing reasons, we:
    (1)   reverse the district court’s decision
    granting summary judgment that
    Bodum’s Version 1 frother infringed the
    patents-in-suit;
    (2)   reverse the district court’s decision
    granting summary judgment that
    Bodum’s Version 2 frother infringed the
    ’122 Patent;
    (3)   reverse the district court’s decisions pre-
    cluding Bodum from introducing prior
    art that was disclosed during discovery
    and preventing Jorgen Bodum from tes-
    tifying as to the Bodum 3-Cup French
    Press and other prior art evidence;
    (4)   reverse the district court’s decision bar-
    ring Bodum’s expert from testifying on
    the issue of obviousness;
    (5)   reverse the district court’s decision pre-
    cluding Bodum from introducing any
    evidence of inequitable conduct;
    (6)   vacate the district court’s decision deny-
    ing Bodum JMOL that it did not will-
    fully infringe the patents-in-suit and
    therefore vacate the jury’s verdict of
    willfulness; and
    (7)   vacate the district court’s decision en-
    hancing damages and awarding attor-
    ney fees to Meyer.
    This case is remanded for further proceedings consis-
    tent with this opinion.

    DYK, Circuit Judge, concurring.
    While I agree with and join the thorough majority
    opinion, in looking at this case from a broader perspec-
    tive, one cannot help but conclude that this case is an
    example of what is wrong with our patent system. The
    patents essentially claim the use of a prior art French
    press coffee maker to froth milk. Instead of making coffee
    by using the plunger to separate coffee from coffee
    grounds, the plunger is depressed to froth milk. The idea
    of frothing cold milk by the use of aeration rather than
    steam is not new as reflected in the prior art Ghidini
    patent. Under the Supreme Court’s decision in KSR
    International Co. v. Teleflex, Inc., 
    550 U.S. 398

    MEYER INTELL PROP   v. BODUM                               2
    (2007), and its predecessors, it would be reasonable to
    expect that the claims would have been rejected as obvi-
    ous by the examiner, and, if not, that they would have
    been found obvious on summary judgment by the district
    court. But no such thing. The parties have spent hun-
    dreds of thousand of dollars and several years litigating
    this issue, and are invited by us to have another go of it in
    a second trial. Such wasteful litigation does not serve the
    interests of the inventorship community, nor does it fulfill
    the purposes of the patent system.
