    Before PROST, Chief Judge, WALLACH and TARANTO,
    Circuit Judges.
    TARANTO, Circuit Judge.
    Chrimar Systems, Inc., filed a patent infringement
    suit against ALE USA Inc. (formerly known as Alcatel-
    Lucent Enterprise USA Inc.). In response, ALE asserted
    numerous defenses and counterclaims, including a claim
    of fraud under Texas law. As relevant here, a jury found
    infringement by ALE and awarded damages to Chrimar,
    and it rejected ALE’s fraud claim. The court entered
    judgment in favor of Chrimar on those issues. The court
    also denied Chrimar’s post-trial motion for attorney fees
    under 35 U.S.C. § 285. Both parties appeal. We reject
    one of the claim constructions adopted by the district
    court, but we affirm the damages award, the judgment on
    ALE’s fraud claim, and the denial of fees.
    I
    A
    Chrimar owns four related patents—U.S. Patent Nos.
    8,155,012; 8,942,107; 8,902,760; and 9,019,838—whose
    specifications are materially the same for present purpos-
    es. We treat the ’012 patent’s specification as representa-
    tive. The specification describes the use of devices that
    connect to a wired network, such as Ethernet, and that
    manage or track remote electronic equipment, such as a
    personal computer, on that network. ’012 patent, col. 1,
    lines 23–26, 37–39. In the arrangement described, such
    equipment, called an “asset,” has a tracking device, called
    a “remote module,” attached internally or externally to it.
    
    Id., col. 1,
    line 66 through col. 2, line 2. The asset can be
    managed, tracked, or identified by using the remote
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.                  3
    module to communicate a unique identification number,
    port identification, or wall jack location to the network
    monitoring equipment, or “central module.” 
    Id., col. 3,
    lines 22–27; see 
    id., col. 8,
    line 58 through col. 9, line 23;
    see also 
    id., col. 6,
    lines 48–67 & Fig. 4. Asset identifica-
    tion may be done without using existing network band-
    width, because the remote module can convey information
    about the asset to the central module through the same
    wiring or cables that convey the high-frequency data on
    the network, without adversely affecting the high-
    frequency data. See 
    id., col. 3,
    lines 10–12; 
    id., col. 11,
    line 64 through col. 12, line 1 (“The system transmits a
    signal over preexisting network wiring or cables without
    disturbing network communications by coupling a signal
    that does not have substantial frequency components
    within the frequency band of network communications.”).
    And asset identification does not require that the asset be
    powered on. 
    Id., col. 4,
    lines 65–67; 
    id., col. 12,
    lines 48–
    50.
    According to Chrimar, all four patents are standard-
    essential patents in that they cover features required by
    the Institute of Electrical and Electronics Engineers
    (IEEE) Power over Ethernet (PoE) 802.3af standard
    (ratified in 2003) and 802.3at amendments to the IEEE
    PoE 802.3 standard (ratified in 2009). Those standards
    address detection, classification, power-on, operating
    power, and removal of power. Chrimar’s patents cover
    the first three features (detection, classification, and
    power-on).
    A Power over Ethernet controller chip controls the ac-
    tivities addressed in the standard relevant here. Products
    with such a controller chip interact with other products to
    enable the safe delivery of power from power-sourcing
    equipment (e.g., switches) to powered devices (e.g., wire-
    less access points and voice over internet protocol (VoIP)
    phones). ALE sells VoIP phones, wireless access points,
    4                  CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    and switches that implement the IEEE PoE 802.3af/at
    standard.
    B
    The IEEE ratified the PoE 802.3af standard in 2003.
    That ratification followed a series of meetings convened
    by the IEEE regarding adoption of the standard. John
    Austermann, Chrimar’s Chief Executive Officer and listed
    inventor on the patents, participated in several such
    meetings in 2000.
    Under the then-applicable bylaws of the IEEE Stand-
    ards Association Board (2000)—which have since been
    changed—if the IEEE knew of an essential patent, the
    IEEE could adopt a standard that includes the known use
    of that patent or patent application “if there is technical
    justification in the opinion of the standards-developing
    committee and provided the IEEE receives assurance
    from the patent holder that it will license under reasona-
    ble terms and conditions for the purpose of implementing
    the standard.” J.A. 10548. The bylaws also stated that
    the letter of assurance “shall be provided without coer-
    cion,” J.A. 10548; and the IEEE Standards Association
    operations manual required that the working group “shall
    request that known patent holders submit statements”
    but that the working group refrain from coercing the
    patent holders to do so, J.A. 6711. According to Chrimar’s
    expert Clyde Camp, who served as Chair of the IEEE
    Patent Committee, the IEEE’s patent policy at the time
    was one of “request and encourage,” J.A. 6706, consisting
    of sending letters to owners of patents that may be essen-
    tial and requesting (without requiring) that the patent
    owner return a “Letter of Assurance,” J.A. 6705–09; see
    also J.A. 6713–14 (IEEE 2002 statement submitted to
    FTC: “Disclosure of patents is based on the willingness of
    the individual participants to disclose any known patents
    whose use would be required in the practice of the stand-
    ard.”). Mr. Camp also testified that patent holders did not
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.                5
    always provide a letter of assurance in response to such
    requests. J.A. 6712. 1
    In October 2001, while the relevant IEEE component
    was considering the adoption of the PoE 802.3af standard,
    Chrimar expressed its belief to the IEEE that the Chri-
    mar-owned U.S. Patent No. 5,406,260—not asserted in
    this case—was an essential patent for that standard.
    Chrimar submitted a “letter of assurance” agreeing to
    license the ’260 patent upon request “to all applicants at
    royalty rates that [Chrimar] deems reasonable in light of
    the specific circumstances of this particular situation.”
    J.A. 10559. The IEEE never requested, and Chrimar did
    not submit, any similar letter regarding the four patents
    asserted in this case.
    C
    In 2015, Chrimar sued ALE in the Eastern District of
    Texas for direct and indirect infringement of the ’012,
    ’107, ’838, and ’760 patents under 35 U.S.C. §§ 271(a), (b).
    ALE asserted defenses of, inter alia, noninfringement,
    invalidity (including anticipation, obviousness, lack of
    enablement, lack of sufficient written description, and
    lack of proper inventorship), unenforceability based on
    unclean hands and inequitable conduct, prosecution
    laches, equitable estoppel, waiver, and implied license.
    ALE also asserted counterclaims of, inter alia, breach of
    contract with the IEEE (with ALE as a third-party benefi-
    ciary), fraud, and violation of section 2 of the Sherman
    Act, as well as declaratory judgment counterclaims corre-
    sponding to several of ALE’s affirmative defenses.
    The court issued a claim construction order in late
    March 2016. Chrimar Sys., Inc. v. Alcatel-Lucent USA,
    Inc., No. 6:15-cv-163, 
    2016 WL 1228767
    (E.D. Tex. Mar.
    1   In 2004, the IEEE changed its policy to require
    the submission of letters of assurance.
    6                   CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    28, 2016) (Claim Construction Order I). Two weeks before
    trial, on September 20, 2016, ALE stipulated to infringe-
    ment of claims 1, 5, 72, and 103 of the ’107 patent and
    claims 1, 7, and 26 of the ’838 patent under the governing
    claim construction order; and ALE requested further
    construction of the claim terms “adapted” and “physically
    connect” in the asserted claims of the ’012 and ’760 pa-
    tents. A week later, the court issued a second claim
    construction order construing those terms. Chrimar Sys.,
    Inc. v. Alcatel-Lucent USA, Inc., No. 6:15-cv-163, 
    2016 WL 5393853
    (E.D. Tex. Sept. 27, 2016) (Claim Construction
    Order II). In light of that order, ALE, on September 30,
    2016, stipulated to infringement of claims 31, 35, 43, and
    60 of the ’012 patent and claims 1, 59, 69, 72, and 145 of
    the ’760 patent. 2
    In late June 2016, ALE moved to strike the expert re-
    port and exclude the testimony of Chrimar’s damages
    expert, Robert Mills, arguing that, in his damages calcu-
    lation, he did not properly limit compensation to the value
    of the patented features of ALE’s products, i.e., he did not
    adequately separate the value of the patented features
    2    The claims of the ’107, ’838, ’012, and ’760 patents
    to which ALE stipulated infringement in this case were
    all determined to be unpatentable by the Patent Trial and
    Appeal Board in four final written decisions. Appeals
    from the final written decisions for the first three patents
    have been filed with this court. Notice of Appeal, Chri-
    mar Sys., Inc. v. Juniper Networks, Inc., No. 18-1499 (Fed.
    Cir. Feb. 1, 2018), ECF No. 1; Notice of Appeal, Chrimar
    Sys., Inc. v. Juniper Networks, Inc., No. 18-1500 (Fed. Cir.
    Feb. 1, 2018), ECF No. 1; Notice of Appeal, Chrimar Sys.,
    Inc. v. Juniper Networks, Inc., No. 18-1503 (Fed. Cir. Feb.
    1, 2018), ECF No. 1. ALE has not yet appealed the final
    written decision regarding the ’760 patent, entered by the
    Board on April 26, 2018.
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.               7
    from the value of nonpatented features and the value
    associated with the IEEE standardization. In August
    2016, the court granted the motion only in part. The
    court concluded that, for admissibility, Mr. Mills had
    adequately separated patented from nonpatented fea-
    tures. But the court concluded that Mr. Mills improperly
    stated in his report that there was no need even to assess
    the value of standardization because, when the IEEE
    standard was adopted, there were no noninfringing alter-
    natives to the features at issue; the court struck that
    statement. Mr. Mills then submitted a supplemental
    report, as authorized, addressing the value of standardi-
    zation. When ALE again moved to strike and exclude, the
    court again granted ALE’s motion only in part, striking
    from the supplemental report one sentence about the lack
    of noninfringing alternatives at the time the standard was
    adopted.
    A jury trial was held in early October 2016. ALE
    dropped many of its defenses and counterclaims shortly
    before or during trial and, as mentioned previously,
    stipulated to infringement under the governing claim
    constructions shortly before trial. The issues submitted to
    the jury were infringement damages, invalidity based on
    improper inventorship, fraud, and breach of contract. On
    October 7, 2016, the jury returned a verdict in favor of
    Chrimar on all issues and awarded Chrimar a royalty of
    $324,558.34. The defenses of equitable estoppel, waiver,
    prosecution laches, and inequitable conduct were left to
    the court, which ruled for Chrimar on all issues.
    After the jury trial, Chrimar filed a motion for attor-
    ney fees under 35 U.S.C. § 285, and ALE moved for judg-
    ment as a matter of law or a new trial. The court denied
    both motions. Chrimar Sys., Inc. v. Alcatel-Lucent Enter.

    entered final judgment.
    ALE timely appealed. Chrimar timely cross-appealed.

    II
    ALE appeals three of the district court’s claim con-
    structions, the denial of its motion to exclude Mr. Mills’s
    damages testimony, and the jury instruction on ALE’s
    state-law fraud claim.
    A
    We review de novo a district court’s claim construc-
    tion, while reviewing for clear error any underlying factu-
    al findings. Teva Pharms. USA, Inc. v. Sandoz, Inc., 
    135 S. Ct. 831
    , 840–42 (2015). ALE challenges the district
    court’s construction of (1) “adapted,” as used in the rele-
    vant claims of the ’012 patent; (2) a series of infinitive
    phrases in the relevant claims of the ’107, ’760, and ’838
    patents; and (3) “physically connect,” as used in the
    relevant claims of the ’760 patent. We agree on the first
    issue, not the others.
    1
    ALE objects to the court’s construction of “adapted” in
    claim 31 of the ’012 patent (on which claims 35, 43, and
    60 directly or indirectly depend). That claim reads:
    31. An adapted piece of Ethernet data termi-
    nal equipment comprising:
    an Ethernet connector comprising a plurality
    of contacts; and
    at least one path coupled across selected con-
    tacts, the selected contacts comprising at least one
    of the plurality of contacts of the Ethernet con-
    nector and at least another one of the plurality of
    contacts of the Ethernet connector,
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.                  9
    wherein distinguishing information about the
    piece of Ethernet data terminal equipment is as-
    sociated to impedance within the at least one
    path.
    ’012 patent, col. 18, line 62 through col. 19, line 5 (empha-
    sis added).
    In this case, the district court, at the parties’ request,
    adopted the construction of “[a]n adapted piece of Ether-
    net data terminal equipment” from an earlier case in
    which the same court construed the preamble in claim 31
    of the ’012 patent. See Claim Construction Order II, 
    2016 WL 5393853
    , at *1, *3 (referring to ChriMar Sys., Inc. v.
    Alcatel-Lucent, Inc., No. 6:13-cv-880, 
    2015 WL 233433
    ,
    at *7–9 (E.D. Tex. Jan. 8, 2015) (6:13-cv-880 Claim Con-
    struction Order)). In the claim construction order entered
    in the earlier case, the court construed the preamble as
    “limiting” and stated that its “plain and ordinary mean-
    ing” should govern its scope, a construction with which
    both parties to that case agreed. 3 6:13-cv-880 Claim
    Construction Order, 
    2015 WL 233433
    , at *9. While ac-
    knowledging that the parties continued to dispute the
    meaning of the term “adapt,” 
    id., the court
    in that order
    reasoned:
    The “adapting” requirement in the claims of the
    ’012 Patent is essential to address the problem
    confronted by the inventors taking existing net-
    works and adapting them to make equipment dis-
    3    That case, filed in 2013, involved Chrimar and Al-
    catel-Lucent. (The present case involves Chrimar and
    ALE USA Inc., which was spun off from Alcatel-Lucent in
    2014.) With the parties’ agreement, the 2013 case was
    dismissed without prejudice in June 2015. Chrimar Sys.,
    Inc. v. Alcatel-Lucent, Inc., No. 6:13-cv-880 (E.D. Tex. Jan.
    8, 2015), ECF No. 140.
    10                  CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    tinguishable. Thus, the word “adapting” must
    have some meaning.
    
    Id. The court
    did not say more about what that “mean-
    ing” is. See 
    id. Two weeks
    before trial in the present case, ALE asked
    for further claim construction of the term “adapted.”
    Claim Construction Order II, 
    2016 WL 5393853
    , at *1.
    According to ALE, the term should be construed as a
    “modification of preexisting equipment.” See 
    id. at *3.
    The court disagreed with that narrowing construction. 
    Id. at *4.
    Instead, the court construed the term “consistently
    with its plain and ordinary meaning to mean ‘designed,
    configured, or made.’” 
    Id. at *3–4.
         In light of the parties’ agreement in this case that the
    preamble is limiting, both before the district court and on
    appeal, see ALE Br. 12; Chrimar Br. 18 n.5, we disagree
    with the district court’s claim construction. Generally,
    every apparatus may be described as “designed, config-
    ured, or made,” and Chrimar has not explained how that
    construction in any way limits the scope of claim 31.
    Chrimar also contends that “piece of Ethernet data ter-
    minal equipment,” rather than “adapted,” is the limiting
    term in the preamble, but it does not explain how the
    former is limiting. Chrimar Br. 20–21. The district court
    did not adopt that position. See Claim Construction Order
    II, 
    2016 WL 5393853
    , at *3–4; see also 6:13-cv-880 Claim
    Construction Order, 
    2015 WL 233433
    , at *9 (assuming
    that “the word ‘adapting’ must have some meaning”).
    The specification is consistent with giving “adapted” a
    meaning tied to existing equipment to avoid stripping the
    concededly limiting claim language of meaning. The
    specification describes the invention generally as designed
    to operate on a preexisting network connected to pieces of
    networked terminal equipment. See ’012 patent, col. 3,
    lines 18–22 (“In accordance with the teachings of the
    present invention, a communication system is provided
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.               11
    for generating and monitoring data over a pre-existing
    wiring or cables that connect pieces of networked comput-
    er equipment to a network.”); 
    id., col. 1,
    line 67 through
    col. 2, line 2 (“[A] method for permanently identifying an
    asset by attaching an external or internal device to the
    asset and communicating with that device using existing
    network wiring or cabling is desirable.”). As the district
    court noted, moreover, the specification states that “[t]his
    invention is particularly adapted to be used with an
    existing Ethernet communications link or equivalents
    thereof,” ’012 patent, col. 3, lines 35–37, and that “[t]he
    communication system 15 and 16 described herein is
    particularly adapted to be easily implemented in conjunc-
    tion with an existing computer network 17 while realizing
    minimal interference to the computer network,” 
    id., col. 4,
    lines 56–60. Claim Construction Order II, 
    2016 WL 5393853
    , at *3; see also 6:13-cv-880 Claim Construction
    Order, 
    2015 WL 233433
    , at *9 (stating that “[t]he ‘adapt-
    ing’ requirement in the claims of the ’012 Patent is essen-
    tial to address the problem confronted by the inventors
    taking existing networks and adapting them to make
    equipment distinguishable” and therefore “must have
    some meaning”).
    Chrimar does not dispute that the specification de-
    scribes embodiments that require modification of a preex-
    isting piece of Ethernet data terminal equipment. Nor
    does it dispute that “adapted” appears only in the claims
    of the ’012 patent, not the other patents involving essen-
    tially the same specification, suggesting that the claim
    scope chosen for the asserted claims in this patent is only
    a subset of what the specification may support. 4 It is
    4    The district court noted that the patent describes
    at least one embodiment in which the invention is imple-
    mented at the manufacturing stage, rather than through
    a modification of already-manufactured equipment.
    12                  CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    hardly unknown for one set of claims to use language that
    picks out one among several embodiments, especially
    where other claims (perhaps in the same or related pa-
    tents) claim more broadly or focus on other embodiments.
    E.g., Advanced Cardiovascular Sys., Inc. v. Medronic,
    Inc., 
    265 F.3d 1294
    , 1305–06 (Fed. Cir. 2001) (refusing to
    apply limitations expressed in prosecution histories of
    related patents where relevant claim term was not in-
    cluded in claims of the asserted patent and “[t]he patent-
    ee’s whole point in filing the application that resulted in
    the [asserted patent] was to secure broader claims”); see
    also, e.g., Haemonetics Corp. v. Baxter Healthcare Corp.,
    
    607 F.3d 776
    , 782 (Fed. Cir. 2010) (construing term
    “centrifugal unit” differently in two separate claims in the
    same patent where language in each claim tracked differ-
    ent embodiments described in the specification). The
    claim language here, to be meaningful, requires such a
    construction of “adapted.” We therefore adopt ALE’s
    proposed construction of “adapted” to mean “modified.”
    2
    ALE also objects to the constructions of the infinitive
    phrases “to detect,” “to control,” “to provide,” and “to
    distinguish” in the relevant claims of the ’838 patent; “to
    draw,” “to result,” and “to convey” in the relevant claims

    U.S.C. § 112, ¶ 6 because they do not recite sufficient
    structure to perform the required function. 5 The district
    court rejected that argument. So do we.
    The district court properly recognized the presump-
    tion against application of § 112, ¶ 6 where, as here, the
    word “means” is not used in the claim and properly asked
    whether the terms preceding the infinitive phrases—
    “central piece of equipment,” “Ethernet terminal equip-
    ment” (or “BaseT Ethernet terminal equipment”), and
    “end device”—identify structures or instead are, like
    “means,” essentially place-holder nonce words. Claim

    meaning as the name for structure.”). ALE did not dis-
    pute before the district court, and has not disputed on
    appeal, that those terms refer to known structures in the
    art. Claim Construction Order I,

    ALE argues that the district court erred in construing
    “physically connect”—as used in claim 1 of the ’760 patent
    (on which claims 59, 69, and 72 depend) and claim 73 of
    the ’760 patent (on which claim 145 depends). Claim 1
    reads:
    1. A BaseT Ethernet system comprising:
    a piece of central BaseT Ethernet equipment;
    a piece of BaseT Ethernet terminal equip-
    ment; and
    data signaling pairs of conductors comprising
    first and second pairs used to carry BaseT Ether-
    net communication signals between the piece of
    central Ethernet BaseT Ethernet equipment and
    the piece of BaseT Ethernet terminal equipment,
    the first and second pairs physically connect be-
    tween the piece of BaseT Ethernet terminal
    equipment and the piece of central BaseT Ether-
    net equipment having at least one DC supply, the
    piece of BaseT Ethernet terminal equipment hav-
    ing at least one path to draw different magnitudes
    of current flow from the at least one DC supply
    through a loop formed over at least one of the con-
    ductors of the first pair and at least one of the
    conductors of the second pair, the piece of central
    BaseT Ethernet equipment to detect at least two
    different magnitudes of the current flow through
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.                15
    the loop and to control the application of at least
    one electrical condition to at least two of the con-
    ductors.
    ’760 patent, col. 17, lines 15–36 (emphasis added).
    The district court considered dependent claim 71 (not
    asserted in this case), in which the only additional limita-
    tion is that “the first and second pairs are physically
    connected between the piece of BaseT Ethernet terminal
    equipment and the piece of central BaseT Ethernet
    equipment.” 
    Id., col. 21,
    lines 28–30 (emphasis added). In
    light of that dependent claim and the presumption of
    claim differentiation, the court stated that the term
    “physically connect” in claim 1 requires only that the
    components be configured (have the ability) to physically
    connect, rather than actually be physically connected (as
    in claim 71). Claim Construction Order II, 
    2016 WL 5393853
    , at *4–5.
    On appeal, ALE argues that the district court’s con-
    struction renders the term “physically connect” meaning-
    less and that, without an actual physical connection, the
    system would be inoperable. But requiring that a system
    be configured to physically connect is a meaningful limita-
    tion (it imports a meaningful capability), and such a
    system is operable (upon action by a user, the system
    makes the physical connection needed for actual opera-
    tion). Not surprisingly, it is hardly uncommon for an
    apparatus or system claim, as a claim to a product rather
    than a process (or a forbidden mix), to be directed to
    capability, instead of actual operation. Finjan, Inc. v.
    Secure Computing Corp., 
    626 F.3d 1197
    , 1204 (Fed. Cir.
    2010) (“[W]e have held that, to infringe a claim that
    recites capability and not actual operation, an accused
    device need only be capable of operating in the described
    mode.” (citation and quotation marks omitted)); see, e.g.,
    Ericsson, Inc. v. D-Link Sys., Inc., 
    773 F.3d 1201
    , 1217
    (Fed. Cir. 2014) (affirming infringement verdict based on
    16                  CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    claims directed to components “reasonably capable of
    ‘arranging information for transmission . . . which identi-
    fies a type of payload information’” (quoting U.S. Patent
    No. 6,466,568, col. 13, lines 12–18)); 
    Finjan, 626 F.3d at 1204

    claims describ[ing] capabilities without requiring that any
    software components be ‘active’ or ‘enabled’” because
    “software for performing the claimed functions existed in
    the products when sold—in the same way that an auto-
    mobile engine for propulsion exists in a car even when the
    car is turned off”). Chrimar cites no authority barring a
    claim to a component “configured to” work and capable of
    operation by a user, where the user’s actual operation is
    unclaimed. See Versata Software, Inc. v. SAP Am., Inc.,
    
    717 F.3d 1255
    , 1262–63 (Fed. Cir. 2013) (affirming in-
    fringement verdict based on evidence that the system
    would operate in an infringing manner if a user followed
    the accused infringer’s instructions, and explaining that
    “[w]hile a device does not infringe simply because it is
    possible to alter it in a way that would satisfy all the
    limitations of a patent claim, . . . an accused product may
    be found to infringe if it is reasonably capable of satisfy-
    ing the claim limitation” (citation and quotation marks
    omitted)). Thus, ALE has not provided any reason that
    overcomes the presumption in favor of claim differentia-
    tion. See Phillips v. AWH Corp., 
    415 F.3d 1303
    , 1315
    (Fed. Cir. 2005) (en banc).

    We affirm the judgment of infringement of the ’107,
    ’838, and ’760 patents. Because we agree with ALE as to
    the term “adapted” in the ’012 patent, we vacate the
    district court’s claim construction order as to that term.
    We remand for further proceedings on infringement of the
    ’012 patent under the proper construction of “adapted.”
    That result does not call for a new trial on damages.
    ALE did not ask for a new trial on damages based on our
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.                17
    adoption of its construction of “adapted.” See ALE Br. 21
    (requesting only reversal of the infringement judgment);
    ALE Reply Br. 11 (requesting that the court either “re-
    verse or vacate the infringement judgment . . . so that the
    fact finder may assess whether the accused products
    infringe the asserted claims of the ’012 patent under a
    proper construction”). And a new trial on damages is not
    warranted on that basis. Chrimar’s technical expert Dr.
    Vijay Madisetti testified that all four patents “cover the
    PSE [power sourcing equipment] and the PD [power
    device] aspects of classification, detection, and controlling
    the power,” J.A. 5892—a proposition that ALE agrees
    with on appeal, ALE Br. 8. Dr. Madisetti also testified
    that the smallest saleable patent-practicing units are
    ALE’s power sourcing equipment, which infringe the ’760
    and ’838 patents, and ALE’s power devices, which infringe
    the ’012, ’107, and ’760 patents, J.A. 5921—a proposition
    ALE does not dispute on appeal. Given the (affirmed)
    judgment of infringement of the ’107 and ’760 patents, the
    absence of an infringement judgment on the ’012 patent is
    immaterial to damages because any damages that would
    result from the alleged infringement of the ’012 patent
    also results from the infringement of the ’107 and ’760
    patents. We therefore proceed to consider ALE’s inde-
    pendent arguments directed to damages.
    B
    ALE challenges the damages award by attacking the
    testimony of Mr. Mills, Chrimar’s damages expert. Ac-
    cording to ALE, Mr. Mills, in calculating a reasonable
    royalty, (1) relied on licenses not comparable to the hypo-
    thetical negotiation for the present case; (2) did not ade-
    quately separate the value of patented features from the
    value of standardization and the value of nonpatented
    features; and (3) prejudicially referred to ALE’s total net
    revenue and profit. The challenge is most naturally
    viewed as a challenge to the admission of Mr. Mills’s
    testimony, reviewable for abuse of discretion. See Gen.
    18                 CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    Elec. Co. v. Joiner, 
    522 U.S. 136
    , 138–39 (1997); 
    Versata, 717 F.3d at 1261
    (applying Fifth Circuit law); Snap-
    Drape, Inc. v. Comm’r, 
    98 F.3d 194
    , 197 (5th Cir. 1996).
    Our conclusion would not change even if we viewed ALE’s
    argument as challenging the denial of judgment as a
    matter of law, reviewed de novo for compliance with the
    deferential standard for such challenges to jury verdicts,
    see Mirror Worlds, LLC v. Apple Inc., 
    692 F.3d 1351
    ,
    1356–57 (Fed. Cir. 2012) (applying Fifth Circuit law), or
    the denial of a new trial, reviewed for an abuse of discre-
    tion, see LaserDynamics, Inc. v. Quanta Computer, Inc.,
    
    694 F.3d 51
    , 66 (Fed. Cir. 2012) (applying Fifth Circuit
    law).
    1
    There is no reversible error based on Mr. Mills’s
    reliance on certain licenses to come to a range for a rea-
    sonable royalty rate and his selection of a rate in the low
    end of that range—i.e., $2.50 per PoE port.             See
    J.A. 6223–28 (Mills’s trial testimony); see also J.A. 6164–
    89 (testimony of Chrimar CEO Austermann going
    through 30 licenses). To the extent that ALE argues that
    those licenses were not sufficiently comparable to be
    reliable indicators of what would have occurred in a
    hypothetical negotiation between it and Chrimar, ALE
    failed to make that challenge when seeking to exclude Mr.
    Mills’s testimony or when that testimony was presented
    at trial. See JMOL Order, 
    2017 WL 568712
    , at *6 & n.7.
    In addition, ALE was able to—and did—attack any dis-
    crepancies in the license-comparison approach by present-
    ing extensive contrary testimony from its expert.
    J.A. 6807–27. This court has approved reliance on licens-
    es, which often will not be in identical circumstances, as
    long as reasonable adjustments for differences in contexts
    are made. See, e.g., Prism Techs. LLC v. Sprint Spectrum
    L.P., 
    849 F.3d 1360
    , 1368–70 (Fed. Cir. 2017) (citing
    cases). ALE has not persuasively shown either an unrea-
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.             19
    sonable methodology or prejudicial error under that
    standard.
    2
    Nor has ALE shown reversible error regarding Mr.
    Mills’s testimony as to apportionment—separating the
    patented features’ value from other elements of value in
    the accused products. Mr. Mills explained at trial that he
    accounted for the products’ non-PoE functionality (non-
    patented functionality outside the PoE standard), the
    products’ nonpatented PoE functionality (two nonpatent-
    ed features of the PoE standard: operating power and
    removal of power), and the value of standardization
    (generally requiring practice of a standard-essential
    patent rather than noninfringing alternatives). J.A. 6239.
    For the first, he calculated the “profit premium” of the
    PoE functionality, comparing ALE’s products that differ
    only in the addition of that functionality. See J.A. 6240–
    42. In apportioning the value of that profit premium to
    each of the nonpatented and patented features of the PoE
    standard, Mr. Mills relied on the testimony of the tech-
    nical expert, Dr. Madisetti, who stated that the patents
    “are fundamental to the provision of PoE under the
    standards” and “relate to the majority and the most
    critical aspects of the standard”; that “the standards
    would not be successful without Chrimar’s inventions”;
    and that “the standards would not have gained wide-
    spread adoption without Chrimar’s patented inventions.”
    J.A. 6243–44; see also J.A. 4642–43 (Mills expert report
    relying on Dr. Madisetti’s explanation); J.A. 5878, 5887–
    88, 5892 (Madisetti testimony). Mr. Mills also testified
    that, although there was some value attributable to the
    nonpatented features of the PoE standard and to stand-
    ardization, he adopted a conservative estimate of the
    profit premium attributable to the patented features
    ($2.50 per PoE port), which did not include those values.
    J.A. 6244–45 (relying on Dr. Madisetti’s testimony regard-
    ing the value of standardization and the nonpatented
    20                 CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    features of the PoE standard, and stating that the testi-
    mony “ultimately tells me that $2.50 per port is inherent-
    ly reasonable”).
    Mr. Mills’s opinion that his conservative estimate of
    the portion of the profit premium attributable to the
    patented features did not encompass the value of stand-
    ardization and nonpatented features does not flunk
    standards of reliability and reasonableness. See Aqua
    Shield v. Inter Pool Cover Team, 
    774 F.3d 766
    , 771 (Fed.
    Cir. 2014) (noting that royalty calculations often involve
    “approximation and uncertainty”); VirnetX, Inc. v. Cisco
    Sys., Inc., 
    767 F.3d 1308
    , 1328 (Fed. Cir. 2014) (stating
    that “absolute precision” is not required in the task of
    apportionment, as “it is well-understood that this process
    may involve some degree of approximation and uncertain-
    ty”). Nor is unreliability or unreasonableness established
    by the fact that Mr. Mills’s proposed royalty rate did not
    change in his supplemental report, after he was directed
    to take into account the value of noninfringing alterna-
    tives. Mr. Mills assumed, based on Dr. Madisetti’s testi-
    mony, that the value of nonpatented features of the PoE
    standard and the value of standardization were not large,
    and he selected a figure toward the low end of the range of
    royalty rates from comparable licenses, see J.A. 6223–28,
    including a license that covered comparable technology
    and in which ALE was the licensee, J.A. 6227–28, to reach
    a royalty rate for the patented features. In light of those
    assumptions and his initially conservative estimate, the
    unchanged royalty rate does not prove his method unreli-
    able or unreasonable.
    Mr. Mills’s assumptions underlying his damages theo-
    ry were the subject of cross-examination. ALE used that
    process to suggest that he had neither adequately appre-
    ciated the value of nonpatented features and standardiza-
    tion nor quantified such value. See, e.g., J.A. 6273–84.
    ALE also provided contrary testimony from its own expert
    about the value of standardization and noninfringing
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.              21
    alternatives available at the time the standard was
    adopted (leading to ALE’s proposed royalty rate of $0.05
    per PoE port). J.A. 6824–27. The jury was given instruc-
    tions regarding apportionment (not challenged here),
    including a specific instruction regarding the need to
    factor out the value of standardization and of nonpatented
    features. J.A. 349–50. ALE has not shown reversible
    error in leaving the damages dispute in this case to that
    process.
    3
    ALE’s final challenge regarding damages is that the
    district court improperly allowed Mr. Mills to refer to
    ALE’s total revenue and profit, a reference that, according
    to ALE, “skewed” the damages inquiry. ALE Br. 62. The
    district court, however, allowed that testimony only after
    concluding that ALE had opened the door to it by solicit-
    ing testimony from its own witness that relied on ALE’s
    net revenue to estimate the very large amount that would
    go to Chrimar at ALE’s proposed rate of $0.05 per PoE
    port. J.A. 6316–18. We have no basis for disturbing the
    district court’s determination that ALE opened the door
    and that the now-challenged reference was accordingly
    permissible. See United States v. Keith, 582 F. App’x 300,
    302 (5th Cir. 2014) (no abuse of discretion in “allow[ing]
    the government to elaborate more fully on th[e] line of
    questioning” opened by the defendant) (citing United
    States v. Walker, 
    613 F.2d 1349
    , 1353 (5th Cir. 1980)).

    ALE challenges the district court’s instruction to the
    jury on the law of fraud under Texas law. “[W]e review
    the district court’s determination of state law de novo,
    though the district court still has ‘wide discretion’ in
    formulating the jury charge.” EMJ Corp. v. Hudson
    Specialty Ins. Co., 
    833 F.3d 544
    , 550 (5th Cir. 2016).
    22                  CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    The jury instruction at issue is as follows (challenged
    portions emphasized):
    To prove fraud, ALE must show by a prepon-
    derance of the evidence that Chrimar: (1) made a
    misrepresentation of material fact to ALE,
    (2) with knowledge of its falsity, (3) with the in-
    tent to defraud ALE, (4) which induced justifiable
    reliance by ALE, and (5) which resulted in dam-
    age to ALE. . . .
    In order to prove fraud by omission, ALE must
    show by a preponderance of the evidence that:
    (1) Chrimar concealed or failed to disclose a mate-
    rial fact within its knowledge from ALE;
    (2) Chrimar had a duty to disclose that fact;
    (3) Chrimar knew that ALE was ignorant of the
    fact and ALE did not have an equal opportunity to
    discover the truth; (4) Chrimar intended to in-
    duce ALE to take some action by concealing or
    failing to disclose the fact; (5) ALE relied on
    Chrimar’s non-disclosure; and (6) ALE was in-
    jured as a result of acting without that knowledge.
    J.A. 351–52 (emphases added).
    ALE argues that the instruction improperly excluded
    the possibility that Chrimar’s alleged misrepresentations
    or omissions to the IEEE, in failing to submit a Letter of
    Assurance regarding the four asserted standard-essential
    patents, could support ALE’s fraud claim. 6 ALE relies on
    6  ALE has not disputed Chrimar’s contention on
    appeal that ALE “provided no evidence at trial regarding
    its predecessor’s interest and involvement in the IEEE or
    the PoE standard-setting process.” Chrimar Br. 52 n.19
    (emphasis omitted) (quoting Chrimar Sys., Inc. v. Alcatel-
    Lucent Enter. USA Inc., No. 6:15-cv-163,

    Exxon Corp. v. Emerald Oil & Gas Co., 
    348 S.W.3d 194
    (Tex. 2011), for the proposition that common-law fraud
    under Texas law “does not require proof that the entity
    committing the fraud—here, Chrimar—intended to de-
    fraud the specific party that is making the fraud allega-
    tion.” ALE Br. 68. We see no reversible error in the
    district court’s decision to give the instruction it gave.
    The district court’s instruction mirrors a statement of
    the law in an intermediate Texas court of appeals deci-
    sion, 7979 Airport Garage, L.L.C. v. Dollar Rent A Car
    Sys., Inc., 
    245 S.W.3d 488
    , 507 n.27 (Tex. App. 2007)
    (reciting elements of a Texas state law fraud claim in
    materially identical terms). That decision post-dates the
    Texas Supreme Court’s decision in Ernst & Young, L.L.P.
    v. Pac. Mutual Life Ins. Co., 
    51 S.W.3d 573
    (Tex. 2001),
    which announced the fraud standard later applied by
    
    Exxon, 348 S.W.3d at 218
    –19. And after Exxon, the Fifth
    Circuit itself recited (in an unpublished decision) that
    same statement of the elements of a fraud claim from the
    7979 Airport Garage decision. Shaver v. Barrett Daffin
    Frappier Turner & Engel, L.L.P., 593 F. App’x 265, 271
    (5th Cir. 2014). Unless Exxon clearly showed those rul-
    ings to be incorrect, the district court permissibly followed
    them.
    Exxon does not clearly show those rulings to be incor-
    rect. In Exxon, the court addressed the “intent to induce”
    element of 
    fraud. 348 S.W.3d at 217
    –18 (affirming prin-
    ciple announced in Ernst & 
    Young, 51 S.W.3d at 580
    –82).
    Emerald, a lessor of the O’Connor oil well field, presented
    evidence that Exxon, the previous lessor, filed public
    plugging reports with the Texas Railroad Commission
    with false representations regarding the amount of re-
    serves in the oil field, as well as evidence that “the first
    place subsequent operators turn is to those very filings at
    the Railroad Commission when deciding whether redevel-
    opment can be economically undertaken.” 
    Id. at 216–17.
    The Texas Supreme Court stated that whether a party
    24                   CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    “might or should rely on statements” in such reports
    “alone is not sufficient to establish an intent to induce
    reliance.” 
    Id. at 218.
    Rather, as in § 531 of the Restate-
    ment (Second) of Torts (1977), “[o]ne who makes a fraudu-
    lent misrepresentation is subject to liability to the persons
    or class of persons whom he intends or has reason to
    expect to act or to refrain from action in reliance upon the
    misrepresentation, for pecuniary loss suffered by them
    through their justifiable reliance in the type of transac-
    tion in which he intends or has reason to expect their
    conduct to be influenced.” 
    Id. at 218–19
    (quoting Re-
    statement § 531). As explained by the court:
    [The] “reason-to-expect standard requires more
    than mere foreseeability; the claimant’s reliance
    must be ‘especially likely’ and justifiable, and the
    transaction sued upon must be the type the de-
    fendant contemplated.”       Ernst & 
    Young, 51 S.W.3d at 580
    . . . . Even an obvious risk that a
    misrepresentation might be repeated to a third
    party is not sufficient to satisfy the reason-to-
    expect standard. A plaintiff must show that “[t]he
    maker of the misrepresentation [has] information
    that would lead a reasonable man to conclude that
    there is an especial likelihood that it will reach
    those persons and will influence their conduct.”
    [Restatement] § 531, cmt. d . . . , quoted in Ernst
    & 
    Young, 51 S.W.3d at 581
    .
    
    Id. at 219.
    As a matter of law, the court said, it is not
    enough that Exxon “knew” that subsequent lessors would
    rely on its reports; Exxon must have known that there
    was “an especial likelihood that Emerald specifically
    would rely on the plugging reports in a transaction being
    considered at the time [Exxon] filed the plugging reports.”
    
    Id. The Exxon
    court therefore ruled that the misrepresen-
    tation, even in a public filing, must be directed at the
    defrauded party. That court’s language can fairly be
    viewed in the terms (intent even with some constructive
    CHRIMAR HOLDING CO., LLC   v. ALE USA INC.               25
    aspect) articulated before Exxon in 7979 Airport Garage
    (adopted after Exxon by the Fifth Circuit in Shaver).
    It is true that Texas law “does not require proof that a
    misrepresentation be made to the defrauded party” in the
    sense ALE suggests—in substance, directly to. ALE
    Br. 68. But the jury instructions did not require that the
    misrepresentation or omission be made “directly to” ALE.
    The instructions permitted liability if the misrepresenta-
    tion or omission was made to ALE, whether directly or
    indirectly. See Neuhaus v. Kain, 
    557 S.W.2d 125
    , 138
    (Tex. Civ. App. 1977) (“We recognize the rule that a
    fraudulent representation may be either direct or indi-
    rect”). Perhaps the instruction would have benefited from
    specifying that the fraudulent statement could be made
    “directly or indirectly” to ALE; but ALE made no request
    for inclusion of words to that effect. ALE objected to the
    instruction on the ground that “[w]e think that the evi-
    dence has shown that the – Chrimar has committed fraud
    on the IEEE in general and that it’s not necessary to show
    fraud against ALE in this case.” J.A. 6919. The district
    court could reasonably reject that proposal as incorrectly
    suggesting that neither a direct nor indirect misrepresen-
    tation is required. In these circumstances, ALE lacks a
    meritorious argument on appeal for vacatur of the fraud
    verdict based on erroneous instructions.
    III
    Chrimar cross-appeals the district court’s denial of its
    motion for attorney fees under 35 U.S.C. § 285, which we
    review for abuse of discretion. Highmark Inc. v. Allcare
    Health Mgmt. Sys., Inc., 
    134 S. Ct. 1744
    , 1747 (2014).
    Chrimar’s argument relies chiefly on the ground that
    ALE pressed a large number of defenses and counter-
    claims for years, only to drop most of them (e.g., concern-
    ing antitrust, inequitable conduct, and some invalidity
    grounds) late in the litigation, even during trial. Chrimar
    does not meaningfully show that those dropped claims
    26                   CHRIMAR HOLDING CO., LLC   v. ALE USA INC.
    were objectively meritless. It focuses on the contention
    that ALE never truly intended to try them.
    The district court did not abuse its discretion in mak-
    ing what here was a case-specific judgment that it was
    distinctively well-positioned to make. The court denied
    summary judgment as to a number of the claims ALE
    later dropped, allowing them to proceed. And the court
    determined that ALE’s litigation decisions fell within the
    range of ordinary practices involving the narrowing of
    claims for trial. Fees Order, at 3–4.
    We have considered Chrimar’s arguments that this
    was an exceptional case as a matter of law and find them
    unpersuasive. We therefore affirm the district court’s
    ruling on ALE’s § 285 motion.
    IV
    We vacate in part the district court’s second claim
    construction order—the part adopting a construction of
    “adapted” in claim 31 of the ’012 patent, a construction we
    reject. We affirm the district court’s remaining claim
    constructions and the infringement damages award and
    the fraud judgment. We remand for further proceedings
    consistent with this opinion.
    Each party shall bear its own costs.
