    2               GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    WALLACH, Circuit Judge.
    Following a claim construction ruling adverse to Ap-
    pellant Holland L.P. (“Holland”), a jury in the U.S. Dis-
    trict Court for the Eastern District of Texas (“District
    Court”) found that Holland infringed Appellee
    Georgetown Rail Equipment Company’s (“Georgetown”)
    U.S. Patent 7,616,329 (“the ’329 patent”) and awarded
    Georgetown lost profits. The District Court later ap-
    proved an additional award of enhanced damages based
    on a finding of willful infringement. Holland appeals the
    District Court’s conclusions as to claim construction,
    willful infringement, and enhanced damages, as well as
    its decision to deny Holland’s renewed motion for judg-
    ment as a matter of law (“JMOL”) of noninfringement.

    BACKGROUND
    I. The Patented Technology
    The ’329 patent generally relates to a “system and
    method for inspecting railroad tracks” with the use of
    digital technology. ’329 patent, Abstract. Specifically, it
    discloses a system for inspecting tie plates, which are
    steel plates that connect the steel rail tracks to wooden
    ties. 
    Id. col. 2
    ll. 19−31; J.A. 928. Tie plates can sink or
    cut into the wooden ties and disrupt railroad service. ’329
    patent, Abstract. The ’329 patent purportedly improves
    the prior art by automating the examination of misa-
    ligned tie plates, a process that was historically per-
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.            3
    formed manually with certain software systems. See 
    id. col. 1
    l. 39−col. 2 l. 6 (describing the prior art).
    Claim 16, the only asserted claim, recites:
    A system for inspecting a railroad track bed, in-
    cluding the railroad track, to be mounted on a ve-
    hicle for movement along the railroad track, the
    system comprising:
    at least one light generator positioned ad-
    jacent the railroad track for projecting a
    beam of light across the railroad track
    bed;
    at least one optical receiver positioned ad-
    jacent the railroad track for receiving at
    least a portion of the light reflected from
    the railroad track bed and generating a
    plurality of images representative of the
    profile of at least a portion of the railroad
    track bed; and
    at least one processor for analyzing the
    plurality of images and determining one or
    more physical characteristics of the said
    portion of the railroad track bed, the one
    or more physical characteristics compris-
    ing at least a geographic location of the
    plurality of images along the railroad
    track bed, wherein the processor includes
    an algorithm for detecting a misaligned or
    sunken tie plate of the railroad track bed,
    the algorithm comprising the steps of:
    (a) analyzing a frame of the plural-
    ity of images, the frame compris-
    ing a region of interest;
    4                GEORGETOWN RAIL EQUIP. CO.    v. HOLLAND L.P.
    (b) determining whether the re-
    gion of interest contains a tie
    plate;
    (c) if a tie plate is present, deter-
    mining a crosstie contour and a tie
    plate contour;
    (d) comparing an orientation of the
    crosstie contour and an orientation
    of the tie plate contour; and
    (e) determining whether the tie
    plate is misaligned or sunken
    based upon the comparison.

    l. 40−col. 12 l. 2 (emphasis added).
    II. Relevant Facts and Procedural History
    Holland purchases track and crosstie measuring
    technologies from Rail Vision Systems, J.A. 1072−73, and
    then places those technologies on its own track inspection
    vehicles, called TrackStar vehicles, J.A. 1564. Data from
    the track is collected and then may be sent to third-party
    companies, for example, Rail Vision Europe Ltd., a com-
    pany based in the United Kingdom, for data processing.
    See Georgetown Rail II, 
    2016 WL 3346084
    , at *6. Rail
    Vision Europe Ltd. then sends finished reports back to
    Holland for distribution to Holland’s customers. 
    Id. at *5−6;
    see J.A. 1103−04.
    Georgetown markets similar products that practice
    the ’329 patent as part of its Aurora Track Inspection
    System. J.A. 850. Specifically, the Aurora Track Inspec-
    tion System uses lasers and cameras mounted on a Hi-
    Rail vehicle to collect and process information about track
    ties. J.A. 817−19. The purpose of these types of systems
    is generally to allow customers to use the processed data
    to “manage the logistics of crosstie replacement and to
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.            5
    quantify the need for new crossties.” ’329 patent col. 1
    ll. 39−40; see J.A. 1102−03.
    Holland and Georgetown knew of each other’s place in
    the track-tie market. In January 2012, both companies
    participated in a “head-to-head challenge,” in which they
    demonstrated their services to potential customer Union
    Pacific Railroad (“Union Pacific”). Georgetown Rail II,
    
    2016 WL 3346084
    , at *3 (citations omitted). Following
    the demonstrations, Union Pacific and Holland entered
    into a change order agreement (“Change Order”) to alter
    an existing contract between Holland and Union Pacific to
    allow Holland to provide Rail Vision Systems technology
    to Union Pacific on an as needed basis. Id.; Appellant’s
    Br. 23; Appellee’s Br. 13; J.A. 10741−44. The Change
    Order was signed for a particular number of years and
    included compensatory amounts for actual quantities of
    work performed upon Union Pacific’s request. Appellant’s
    Br. 25–26; J.A. 10742.
    Georgetown sued Holland for infringement in 2013
    and was granted a preliminary injunction in January
    2014, ending any of Holland’s potential sales to Union
    Pacific under the Change Order. Georgetown Rail II,
    
    2016 WL 3346084
    , at *3. The parties proceeded to a jury
    trial, and the jury found that Holland willfully infringed
    the ’329 patent and awarded $1,541,333 in damages. 
    Id. The District
    Court then denied Holland’s motion for
    JMOL and awarded Georgetown an additional $1,000,000
    in enhanced damages based on a finding of willful in-
    fringement pursuant to 35 U.S.C. § 284 (2012). 
    Id. at *12–21.

    ceptional under 35 U.S.C. § 285 and awarded attorney
    fees. Georgetown Rail II,

    , at *21−24.
    6               GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    DISCUSSION
    Holland raises four issues on appeal. First, Holland
    challenges the District Court’s finding that the term
    “mounted on a vehicle for movement along the railroad
    track” in the preamble of claim 16 is not a claim limita-
    tion. Appellant’s Br. 62−66. Second, Holland challenges
    the jury’s infringement finding. 
    Id. at 33−45.
    Third,
    Holland challenges the District Court’s approval of the
    jury’s award of lost profits. 
    Id. at 45−58.
    Fourth, Holland
    argues that we should reverse the District Court’s award
    of enhanced damages. 
    Id. at 58−62.
    We address these
    issues in turn.
    I. Claim Construction
    At the District Court, Holland argued that the phrase
    “mounted on a vehicle for movement along the railroad
    track” in the preamble of claim 16 was a claim limitation,
    such that Holland’s product, which did not have a proces-
    sor capable of mounting on a vehicle, could not infringe.
    Georgetown Rail I, 
    2014 WL 11498109
    , at *2. The Dis-
    trict Court rejected this argument for four reasons. First,
    it found that the term did not recite an “essential struc-
    ture” of the invention because the specification also in-
    cluded the phrase “[a]lternatively, the computer analysis
    can be performed by another computer system having
    image processing software known in the art,” ’329 patent
    col. 7 ll. 12−14, such that the system need not be per-
    formed in a vehicle, Georgetown Rail I, 
    2014 WL 11498109
    , at *2−3. Second, it found that, for the same
    reason, the phrase could not recite “additional structure
    or steps . . . underscored as important by the specifica-
    tion.” 
    Id. at *3
    (capitalization omitted). Third, it found
    that the term was not an “antecedent basis” for the claim
    Holland does not challenge this finding.     See generally
    Appellant’s Br.
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.              7
    terms because “[t]he claim body, neither in whole [n]or in
    part, mentions the phrase ‘mounted on a vehicle.’” 
    Id. Finally, it
    found that Georgetown did not clearly rely on
    the limitation during prosecution because the cited
    statements from the prosecution history did not “distin-
    guish the claimed invention from the prior art by refer-
    ence to the system being mounted on a vehicle.” 
    Id. at *4.
           A. Standard of Review and Legal Standard
    We review the district court’s ultimate construction of
    the claim language de novo. Teva Pharm. USA, Inc. v.
    Sandoz, Inc., 
    135 S. Ct. 831
    , 835 (2015). “[W]hen the
    district court reviews only evidence intrinsic to the patent
    (the patent claims and specifications, along with the
    patent’s prosecution history[2]), the judge’s determination
    will amount solely to a determination of law, and the
    Court of Appeals will review that construction de novo.”
    
    Id. at 841.
    “In cases where . . . subsidiary facts [relating
    to claim construction] are in dispute, courts will need to
    make subsidiary factual findings about that extrinsic
    evidence. These are the evidentiary underpinnings of
    claim construction . . . and this subsidiary factfinding
    must be reviewed for clear error on appeal.” 
    Id. (internal quotation
    marks omitted). Because our analysis of the
    relevant issue here, the preamble, involves an examina-
    tion of only intrinsic evidence, we review the District
    Court’s determination de novo.
    “Whether to treat a preamble as a limitation is a de-
    termination resolved only on review of the en-
    2    A patent’s prosecution history “consists of the
    complete record of the proceedings before the [U.S. Patent
    and Trademark Office (‘USPTO’)],” providing “evidence of
    how the [US]PTO and the inventor understood the pa-
    tent.” Phillips v. AWH Corp., 
    415 F.3d 1303
    , 1317 (Fed.
    Cir. 2005) (en banc) (citation omitted).
    8               GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    tire . . . patent to gain an understanding of what the
    inventors actually invented and intended to encompass by
    the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com,
    Inc., 
    289 F.3d 801
    , 808 (Fed. Cir. 2002) (internal quota-
    tion marks, brackets, and citation omitted); see Applied
    Materials, Inc. v. Advanced Semiconductor Materials Am.,
    Inc., 
    98 F.3d 1563
    , 1572−73 (Fed. Cir. 1996) (stating that
    whether the preamble constitutes a limitation “is deter-
    mined on the facts of each case in light of the overall form
    of the claim, and the invention as described in the specifi-
    cation and illuminated in the prosecution history”).
    “[T]here is no simple test” for understanding the import of
    the preamble, but “we have set forth some general princi-
    ples to guide th[e] inquiry.” Am. Med. Sys., Inc. v. Bio-
    litec, Inc., 
    618 F.3d 1354
    , 1358 (Fed. Cir. 2010).
    “Generally, the preamble does not limit the claims.”
    Allen Eng’g Corp. v. Bartell Indus., Inc., 
    299 F.3d 1336
    ,
    1346 (Fed. Cir. 2002) (citation omitted). However, a
    preamble may be limiting if: “it recites essential struc-
    ture or steps”; claims “depend[] on a particular disputed
    preamble phrase for antecedent basis”; the preamble “is
    essential to understand limitations or terms in the claim
    body”; the preamble “recit[es] additional structure or
    steps underscored as important by the specification”; or
    there was “clear reliance on the preamble during prosecu-
    tion to distinguish the claimed invention from the prior
    art.” Catalina 
    Mktg., 289 F.3d at 808
    (citations omitted).
    The reverse is also true. A preamble is not a claim
    limitation if the claim body “defines a structurally com-
    plete invention . . . and uses the preamble only to state a
    purpose or intended use for the invention.” Rowe v. Dror,
    
    112 F.3d 473
    , 478 (Fed. Cir. 1997). “[P]reamble language
    merely extolling benefits or features of the claimed inven-
    tion does not limit the claim scope without clear reliance
    on those benefits or features as patentably significant.”
    Catalina 
    Mktg., 289 F.3d at 809
    (citations omitted).
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.              9
    B. The District Court Properly Found the Preamble Is Not
    Limiting
    In the context of the entire patent, it is apparent that
    the term “mounted on a vehicle for movement along the
    railroad track” is meant to describe the principal intended
    use of the invention but not to import a structural limita-
    tion or to exclude from the reach of the claims an assem-
    bly that does not include a vehicle mount. Nothing in the
    specification or prosecution history states, or even sug-
    gests, that Georgetown intended to exclude use of tech-
    nology that was structurally identical to its claimed
    product but that was installed and performed analysis on
    a non-vehicle mount. See generally ’329 patent; see J.A.
    10967, 11034, 11043, 11057–58, 11067, 11070, 11078,
    11092–94 (’329 patent prosecution history). The body of
    the claim itself describes a “structurally complete inven-
    tion,” 
    Rowe, 112 F.3d at 478
    , because it describes a closed
    “system” comprised of a “light generator,” “optical receiv-
    er,” and “processor,” which are the objects required to
    perform the stated purposes of gathering and processing
    data on misaligned track ties, ’329 patent, col. 11 ll. 42,
    43, 46, 51; see 
    id., Abstract, col.
    2 ll. 13−34 (Summary of
    the Disclosure). The location of the system is not an
    essential feature of the invention. Indeed, as the District
    Court noted, the specification states that “[t]he computer
    analysis can be performed by the processing device . . .
    located on the inspection vehicle. Alternatively, the
    computer analysis can be performed by another computer
    system having image processing software known in the
    art.” Georgetown Rail I, 
    2014 WL 11498109
    , at *2−3
    (quoting ’329 patent col. 7 ll. 10−14).
    Holland’s arguments do not require us to reach a dif-
    ferent conclusion. First, Holland argues that the specifi-
    cation describes all embodiments of the invention as
    vehicle-based, such that the phrase is “underscored as
    important” by the specification. Appellant’s Br. 63 (inter-
    nal quotation marks and citation omitted). Holland is
    10              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    incorrect. The specification states that the disclosed
    inspection system “can be mounted on an inspection
    vehicle . . . or other device moving along the track so as to
    maintain the inspection system . . . in the proper posi-
    tion.” ’329 patent col. 3 ll. 55−57 (emphasis added). It
    gives additional options that are not vehicle mounts as
    well, such as mounting the system on a “chassis that is
    towed by a vehicle” or on a “locomotive” or “freight car.”
    
    Id. col. 4
    ll. 7−8. The specification also uses the verb “can
    be,” indicating an option rather than a requirement. 
    Id. col. 3
    l. 54. Moreover, the specification describes the
    patented invention as the system itself, noting that to
    mount the system “it is understood that other known
    components . . . may be needed” but do not form the basis
    for the patented invention. 
    Id. col. 3
    ll. 59–60. As the
    District Court noted, the specification explicitly states
    that the relevant computation and processing of the data
    using the patented algorithms and the processing device,
    respectively, also do not need to be performed on or af-
    fixed to a vehicle. Georgetown Rail I, 
    2014 WL 11498109
    ,
    at *2–3; see ’329 patent col. 7 ll. 10−14. For these reasons,
    the phrase “mounted on a vehicle for movement along the
    railroad track” cannot be a part of the essential structure
    of the invention or a “fundamental characteristic” re-
    quired for any part of the claims. Poly-Am., L.P. v. GSE
    Lining Tech., Inc., 
    383 F.3d 1303
    , 1310 (Fed. Cir. 2004).
    Holland’s second argument, that the preamble is “es-
    sential” to understand limitations in the claim body,
    Appellant’s Br. 66 (internal quotation marks and citation
    omitted), fails for the same reason. Contrary to Holland’s
    assertion, the system described in the claim body and in
    the specification is structurally complete without the
    disclosure of how the technology moves over the tracks.
    Holland argues as an example of the need to include the
    preamble in the claim language that the claim terms
    “plurality of images” and light generator and cameras
    that are “positioned adjacent” to the track would not
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.               11
    make sense without the preamble. 
    Id. (internal quotation
    marks omitted). This puts the caboose before the locomo-
    tive. It is easy to imagine that the patented system could
    be manually carried or pulled across tracks, and that
    software configured in any type of device, on-site or off,
    could process the data. These claim terms still would
    apply, because the system, i.e., the “lasers, cameras, and a
    processor,” ’329 patent col. 2 ll. 14–15, still would gener-
    ate a “plurality of images” using a light generator and
    cameras that are “positioned adjacent” to the track, 
    id. col. 1
    1 ll. 43−48. Such a preamble is not limiting “where a
    patentee defines a structurally complete invention in the
    claim body and uses the preamble only to state a purpose
    or intended use for the invention.” Catalina 
    Mktg., 289 F.3d at 808
    (internal quotation marks and citation omit-
    ted).
    Finally, Holland argues that Georgetown relied upon
    the preamble during prosecution to distinguish the inven-
    tion from the prior art. Appellant’s Br. 66−67. Holland
    relies upon Georgetown’s statements that various prior
    art references teach away from the ’329 patent because
    the prior art did not teach “analyzing or determin-
    ing . . . characteristics . . . along the railroad track bed,”
    J.A. 11092 (internal quotation marks and emphasis
    omitted), “utiliz[ing] physical track measurements to
    position the system,” J.A. 11058, or “correlat[ing] meas-
    ured surface characteristics to geographic measured
    locations along roadway/rail surfaces,” J.A. 11034. How-
    ever, none of these statements distinguish the patented
    invention from the prior art based on the mounting of the
    data processor part of the invention onto a vehicle. Am-
    biguous statements made during prosecution, especially
    those that do not directly distinguish the element claimed
    as essential for purposes of finding a limitation in the
    preamble, “cannot fairly limit the characteristics of the
    claim term.” Grober v. Mako Prods., Inc., 
    686 F.3d 1335
    ,
    1342 (Fed. Cir. 2012). For these reasons, we hold that the
    12              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    District Court properly found the preamble does not limit
    the asserted claim term.
    II. Infringement
    At the District Court, Holland argued that it could not
    have infringed because it “did not benefit from or control”
    the purported infringing technology. Georgetown Rail II,
    
    2016 WL 3346084
    , at *5. In denying Holland’s request for
    JMOL, the District Court found that “Holland has provid-
    ed no basis for the [District] Court to reevaluate the
    evidence,” because “[a] reasonable jury could find that
    Holland exercised control of and benefited from” its in-
    fringing Rail Vision Systems device, regardless of the fact
    that a third party, Rail Vision Europe Ltd., processed the
    gathered data.

    cessing would not be put into service,” demonstrating
    “control” of the system. 
    Id. at 1285.
     B. The District Court Did Not Err in Denying JMOL for
    Infringement
    Holland presents two theories why it has not directly
    infringed the ’329 patent pursuant to 35 U.S.C. § 271(a). 3
    First, it alleges that “[n]o reasonable jury could have
    found that Holland ‘used’ . . . the allegedly infringing data
    processing equipment.” Appellant’s Br. 34; see 
    id. at 34−41.
    Second, it claims that no reasonable jury could
    have found that it “offer[ed] to sell” the entire invention
    covered by the ’329 patent, as required under a separate
    theory of infringement. 
    Id. at 42
    (internal quotation
    marks and citation omitted); see 
    id. at 42−45.
    Because we
    resolve this question on the first theory argued by Hol-
    land, we need not address Holland’s arguments related to
    the offer to sell. See Novartis AG v. Noven Pharm., Inc.,
    
    853 F.3d 1289
    , 1296 (Fed. Cir. 2017).
    3   In relevant part, § 271 provides that “whoever
    without authority makes, uses, offers to sell, or sells any
    patented         invention[]     within    the      United
    States . . . infringes the patent.” 35 U.S.C. § 271(a) (em-
    phasis added). Section 271 was not amended in the
    Leahy-Smith America Invents Act, Pub. L. No. 112-29,
    § 3, 125 Stat. 284, 285−93 (2011).
    14              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    In Centillion, this court addressed infringement of a
    system claim on information technology. The claim
    recited a “front-end” system maintained by an end user
    and a “back-end” system maintained by a service provid-
    er. 
    Centillion, 631 F.3d at 1281
    . The facts of the case
    were that customers of the company accused of infringing
    used the company’s front-end client application software
    to trigger data processing by the company’s back-end
    system. See 
    id. at 1281−82.
    Relevant to this case, we
    held that the company’s customers “used” the entire
    system for purposes of § 271(a) because the customers
    entered informational queries into the front-end, and
    these queries caused the back-end to perform additional
    processing as required by the patent claim. 
    Id. at 1285.
    Importantly, we held that “[i]t makes no difference that
    the back-end processing is physically possessed by” a
    third party. 
    Id. Holland’s use
    of Rail Vision Systems’s technology is
    analogous to the system found “used” for purposes of the
    infringement analysis in Centillion. As in Centillion,
    Holland collects and gathers data by its system platform
    on the front-end. J.A. 1137−39. Then, Holland sends the
    gathered information to a back-end third-party company
    with instructions to process and analyze the information.
    J.A. 1106, 1139−40. The fact that the transmission from
    the front-end to the back-end in this case involves “physi-
    cally remov[ing] the hard drives with data . . . and
    ship[ping] them overseas to Rail Vision [Europe Ltd.]” is
    of no consequence.        Appellant’s Br. 38 (citing J.A.
    1103−04). The intermediary steps are still “put into
    service” as a result of Holland’s front-end collection and
    request for processing, demonstrating Holland’s ultimate
    control of, and derivation of benefit from, the system. See
    
    Centillion, 631 F.3d at 1285
    . Holland would have us look
    to the part of Centillion that found the back-end processor
    had not infringed because it only supplied software for the
    customer to use on the front-end. Appellant’s Br. 39−40.
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.             15
    However, this analogy overlooks the finding of infringing
    use by the company’s customers, who were actively using
    and requesting the analysis of their data. J.A. 1126−27,
    1139−40. Here, Holland acts like the customers in Centil-
    lion―its trucks gather and collect the data, and it makes
    the choice to send collected information to the third-party,
    Rail Vision Europe Ltd., for processing.
    Holland argues that, as a factual matter, it may have
    collected and shipped the raw data to Rail Vision Europe
    Ltd., but it has not been proven that Holland actually
    ever gathered any data that was sent for processing.
    Appellant’s Br. 34−37; see Oral Arg. at 3:45−4:09,
    http://oralarguments.cafc.uscourts.gov/default.aspx?fl=20
    16-2297.mp3. Specifically, Holland points to a line in the
    District Court opinion stating that “Holland’s 2012
    demonstration in Yuma is a use of the Rail Vision Sys-
    tems,” Appellant’s Br. 20 (quoting Georgetown Rail II,
    
    2016 WL 3346084
    , at *5), and alleges that there is “no
    evidence that any data collected during the Yuma
    Demonstration was processed by anyone,” 
    id. at 34.
    Regardless of whether the information shown at the
    Yuma Demonstration was ever processed by Rail Vision
    Europe Ltd., Holland’s expert affirmatively stated several
    times on the record that Holland has collected data and
    has directed Rail Vision Systems to process the collected
    data. See J.A. 1135, 1138−39, 1141, 1143−44; see also J.A.
    1103, 1106 (similar). 4 As such, a reasonable jury could
    4     Although these pages have been designated as
    confidential, the information generally contained therein
    was discussed publically at oral argument. Oral Arg. at
    2:19−5:05, 31:51−32:24 (statements made by Holland’s
    attorney), 20:45−21:49 (statements made by Georgetown’s

    find evidence supporting its conclusion that Holland
    infringed Georgetown’s ’329 patent by putting all ele-
    ments of the infringing system into use. That is all that is
    required to uphold the jury finding of infringement.
    III. The District Court Did Not Err in Denying JMOL for
    Damages Based on Lost Profits
    Holland challenges the District Court’s denial of
    JMOL on lost profits damages. At trial, Georgetown
    asserted that Holland’s infringing sales of data collected
    and analyzed from the Rail Vision Systems technology
    caused it to lose profits that it otherwise would have made
    from the ’329 patent. The jury awarded Georgetown
    $1,541,333 in lost profits. Georgetown Rail II, 
    2016 WL 3346084
    , at *7.
    A. Standard of Review and Legal Standard
    As stated above, the Fifth Circuit reviews denials of a
    renewed JMOL de novo. Vanderbilt 
    Mortg., 692 F.3d at 364
    . To recover lost profits, “a patent owner must prove a
    causal relation between the infringement and its loss of
    profits.” Crystal Semiconductor Corp. v. TriTech Microe-
    lecs. Int’l, Inc., 
    246 F.3d 1336
    , 1353 (Fed. Cir. 2001)
    (internal quotation marks and citation omitted). “In other
    words, the burden rests on the patentee to show a reason-
    able probability that but for the infringing activity, the
    patentee would have made the infringer’s sales.” 
    Id. (internal quotation
    marks and citation omitted). “There is
    no particular required method to prove but for causation”
    in patent cases. Mentor Graphics Corp. v. EVE-USA, Inc.,
    
    851 F.3d 1275
    , 1284 (Fed. Cir. 2017). “One useful, but
    non-exclusive method to establish the patentee’s entitle-
    ment to lost profits is the . . . test first articulated by the
    Sixth Circuit” in Panduit Corp. v. Stahlin Brothers Fibre
    Works, Inc., 
    575 F.2d 1152
    (6th Cir. 1978). Mentor
    
    Graphics, 851 F.3d at 1284
    (internal quotation marks and
    citation omitted). Before the District Court, Georgetown
    chose to calculate damages based on a lost profits model
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.               17
    under the four-factor Panduit test. See Georgetown Rail
    II, 
    2016 WL 3346084
    , at *7−8. The Panduit test requires
    the patentee to show: (1) “demand for the patented
    product”; (2) “absence of acceptable noninfringing substi-
    tutes”; (3) “manufacturing and marketing capability to
    exploit the demand”; and (4) “the amount of profit
    that . . . would have [been] 
    made.” 575 F.2d at 1156
    .
    B. Substantial Evidence Supports the Award of
    Lost Profits
    Holland challenges the sufficiency of evidence for
    Panduit factors one and four, arguing that Georgetown’s
    calculation of lost profits had “no legally sufficient eviden-
    tiary basis” to support the District Court’s findings as to
    these factors. Appellant’s Br. 46. We disagree.
    1. Demand for the Patented Product
    As to the first Panduit factor, Holland alleges that
    there is no evidence that Union Pacific demanded
    Georgetown’s patented invention and, instead, evidence
    points to a conclusion that Union Pacific “repeatedly
    rejected” Georgetown’s patented technology. 
    Id. at 49;
    see
    
    id. at 49−53.
    Holland further contends that the evidence
    cannot support demand for the patented product because
    it “consists only of generalized market projections by
    Holland, not Union Pacific,” 
    id. at 51−52
    (citation omit-
    ted), and that Georgetown “fail[ed] to show demand
    during the period of allegedly infringing sales,” 
    id. at 51.
    Holland also states that evidence of demand by other
    Class I railroads cannot satisfy the Panduit test because
    it does not “establish that Union Pacific demanded its
    technology.” 
    Id. Holland improperly
    narrows the scope of the inquiry
    for the first Panduit factor. The proper inquiry asks
    whether demand existed in the marketplace for the
    patented product, i.e., a product “covered by the patent in
    suit or that directly competes with the infringing device.”
    18              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 
    567 F.3d 1314
    , 1330 (Fed. Cir. 2009) (internal quotation
    marks and citation omitted). Georgetown’s Aurora Sys-
    tem and Holland’s Rail Vision Systems are covered by
    claim 16 of the ’329 patent. See supra Section II. Holland
    submitted its own evidence showing that there was de-
    mand for the Rail Vision Systems device at least before
    2011. See J.A. 1113−15, 1127−30. Georgetown submitted
    evidence that its Aurora System generated millions in
    revenue and was contracted out to four U.S. railroad
    companies in long-term contracts, exhibiting strong
    evidence of demand. See J.A. 66, 867−68, 1011−12, 1591,
    10091−147. Although Holland attempts to discredit this
    evidence by stating that Georgetown must show demand
    “during the period of allegedly infringing sales,” Appel-
    lant’s Br. 51 (internal quotation marks and citation
    omitted), Holland again recites an incorrect standard. All
    a patentee must do is “sell[] some item, the profits of
    which have been lost due to infringing sales.” Versata
    Software, Inc. v. SAP Am., Inc., 
    717 F.3d 1255
    , 1265 (Fed.
    Cir. 2013) (internal quotation marks and citation omit-
    ted). Holland has not suggested, nor can it suggest, that
    Georgetown was not selling its Aurora System from 2012
    through 2015 (the period of allegedly infringing sales).
    See generally Appellant’s Br. Thus, we find substantial
    evidence supports a finding that demand for the patented
    product existed, and we decline to disturb the jury’s
    award or the District Court’s denial of Holland’s request
    for JMOL on this basis.
    2. Amount of Profits That Would Have Been Made
    As to the fourth Panduit factor, Holland alleges that
    Georgetown did not submit adequate evidence to show its
    lost profits. 
    Id. at 53−58.
    Georgetown submitted evi-
    dence that its lost profits calculation was based on failure
    to secure a contract with Union Pacific, which entered
    into a deal with Holland instead through the Change
    Order. See Georgetown Rail II, 
    2016 WL 3346084
    , at *8;
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.            19
    J.A. 1600. Holland contends that because it made no
    profit under the Change Order signed with Union Pacific,
    Georgetown could not have missed any potential profits.
    Appellant’s Br. 47. It further alleges that the District
    Court’s assumption that Holland made no profit on the
    Change Order solely due to the January 2014 preliminary
    injunction preventing sales was improper speculation
    running contrary to actual commercial data. 
    Id. at 48.
         Georgetown’s expert calculated lost profits using the
    following method. First, he assumed that had the Change
    Order between Holland and Union Pacific not been im-
    plemented, Union Pacific’s track maintenance business
    would have gone to Georgetown. J.A. 1608−10. Second,
    he calculated that Georgetown would have inspected a
    certain mileage of Union Pacific’s track over a certain
    period at a prevailing market rate. J.A. 1606, 1610−12.
    Third, he accounted for the typical delay between the
    contract’s effective date and the start of Georgetown’s
    hypothetical work. J.A. 1610. He further stated that the
    per-mile rate was on the higher end of comparable ranges
    because it would not have included downward pressure on
    price created with the entrance of the infringing technolo-
    gy into the current market. J.A. 1599−600. Fourth, to
    calculate the length of the contract, he looked at compa-
    rable contracts already entered into between Georgetown
    and four other U.S. railway companies. See J.A. 10148,
    10170, 10179, 10091; see also J.A. 1586, 1608. His pro-
    posed contract length, squarely in the middle of lengths
    contracted with other railroads, was also the same num-
    ber of years as Holland’s Change Order with Union Pacif-
    ic. See J.A. 10742−45. 5 Finally, to keep the estimate
    5    Holland makes an additional argument objecting
    to the lost profits calculation as improper for calculating
    subjective “future” profits that would accrue following
    trial. See Appellant’s Br. 56−57. Georgetown counters
    20              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    within a reasonable range, he did not include more specu-
    lative damages, such as loss of market share or ancillary
    costs. J.A. 1587−88, 1601, 1605.
    Georgetown’s expert used the same method of review-
    ing competitive market contracts to determine the num-
    ber of miles of track to be inspected yearly and to
    approximate the per-mile rates of inspection.           See
    J.A. 1585−618. Both of these numbers were within the
    range of rates in the valid contracts Georgetown main-
    tained with other U.S. railroads. See J.A. 10145, 10160,
    10177, 10198; see also J.A. 860−63. The number used for
    the per-mile rate was also the same calculation that
    Georgetown had submitted in a revised proposal to Union
    Pacific to use its technology in April 2012, an offer which
    Union Pacific did not accept. J.A. 973, 10213. Finally,
    Georgetown’s expert deducted costs to arrive at the final
    calculation. J.A. 1612−18. These cost deductions includ-
    ed job costs, capital expenditures, and deductions for net-
    present value using a standard discount rate.
    J.A. 1613−18.
    Holland’s argument that the award does not reflect
    market or economic variables is belied by the record. “We
    have affirmed lost profits awards based on a wide variety
    of reconstruction theories in which the patentee has
    presented reliable economic evidence of but for causation.”
    Ericsson, Inc. v. Harris Corp., 
    352 F.3d 1369
    , 1377 (Fed.
    Cir. 2003) (internal quotation marks and citation omit-
    that this argument has been waived because it was not
    raised below. See Appellee’s Br. 56 (citing Golden Bridge
    Tech., Inc. v. Nokia, Inc., 
    527 F.3d 1318
    , 1323 (Fed. Cir.
    2008)). Because we find substantial evidence exists to
    support the length of the contract calculation for lost
    profits, we decline to address arguments related to future
    lost profits that are encompassed within the reasonable
    contract length.
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.            21
    ted). That is the case here. Georgetown’s lost profits
    calculation, including contract length, per-mile rate, and
    yearly miles of track to review, was based on sound eco-
    nomic proof confirmed by the historical record. As such,
    Georgetown “made a prima facie showing of lost profits
    and the burden shifted to [Holland] to prove that a differ-
    ent rate would have been more reasonable.” 
    Versata, 717 F.3d at 1267
    (citation omitted); see Mentor 
    Graphics, 851 F.3d at 1285
    −89 (reviewing case law using the Panduit
    test and using similar evidence to award lost profits in a
    two-player market), Crystal 
    Semiconductor, 246 F.3d at 1354
    −57 (calculating lost profits based on similar “market
    variables”). Holland did not make any such showing, nor
    has it alleged that it made a showing of a more reasonable
    damages award. See generally Appellant’s Br.
    Holland also contends that there is no but-for causa-
    tion because Georgetown’s calculations assume that
    Union Pacific would have ordered from Georgetown;
    however, during the same period where Union Pacific
    could have ordered data collection services “as needed”
    from Holland under the Change Order, Union Pacific did
    not purchase any services. 
    Id. at 47−48.
    Losses must be
    “reasonably related” to the infringing activity. Brooktree
    Corp. v. Advanced Micro Devices, Inc., 
    977 F.2d 1555
    ,
    1579 (Fed. Cir. 1992). Georgetown presented evidence
    that the market for its laser-based track inspection ser-
    vices was a two-supplier market. See J.A. 828, 1264,
    1522. Its expert stated that only Georgetown and Holland
    were invited to demonstrate their technologies for Union
    Pacific, J.A. 890−92, and that Union Pacific was interest-
    ed in purchasing this technology and asked for it,
    J.A. 1592. Georgetown provided further evidence that
    Union Pacific entered into a Change Order with Holland
    that contemplated providing the services, J.A. 1626−27,
    and that Union Pacific purchased a certain amount of
    inspection system technologies from Holland before the
    preliminary injunction went into effect, J.A. 1179,
    22              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    10521−24. We conclude that there was a legally sufficient
    evidentiary basis in the record from which a reasonable
    jury could have found that Georgetown would have re-
    ceived business from Union Pacific for data collection
    services if Holland’s infringing product was not in the
    market. Holland presented evidence that: Georgetown
    had offered its services unsuccessfully to Union Pacific
    prior to the relevant time period, J.A. 1627; Union Pacific
    had not authorized work under the Change Order, J.A.
    1627−29; and at all times, even after the Change Order
    was signed, Union Pacific was free to enter into a sepa-
    rate contract for services with Georgetown, J.A. 10740−43
    (demonstrating non-exclusivity of the Change Order).
    The jury weighed that evidence against Georgetown’s and
    found Georgetown’s evidence more persuasive. We may
    not reweigh that evidence here. See Lighting Ballast
    Control LLC v. Philips Elecs. N. Am. Corp., 
    790 F.3d 1329
    , 1342 (Fed. Cir. 2015). Thus, we affirm the District
    Court’s entry of the jury award of lost profits.
    IV. Willfulness and Enhanced Damages
    The final issue before us concerns the District Court’s
    finding of willful infringement and its related decision to
    enhance damages. The District Court found, in relevant
    part, that the jury verdict of willful infringement was
    supported by substantial evidence and that “the totality of
    the circumstances” warranted an award of enhanced
    damages based, in part, on the fact that “Holland contin-
    ued to rely on arguments through trial that were substan-
    tially weak and rejected time and again.” Georgetown
    Rail II, 
    2016 WL 3346084
    , at *15, *17; see 
    id. at *15−21.
    The District Court awarded Georgetown an additional
    $1,000,000 in enhanced damages.

    1341−42 (Fed. Cir. 2016). A district court’s decision to
    award enhanced damages upon a finding of willful in-
    fringement is reviewed for abuse of discretion. Halo
    Elecs., Inc. v. Pulse Elecs., Inc., 
    136 S. Ct. 1923

    When a court is assessing appropriate damages upon
    a finding for the claimant, “the court may increase the
    damages up to three times the amount found or assessed.”
    35 U.S.C. § 284. This case was decided by the District
    Court under the then-applicable willful infringement
    standard. At the time of the decision, proof of willful
    infringement required “clear and convincing evidence that
    the infringer acted despite an objectively high likelihood
    that its actions constituted infringement of a valid patent”
    and that “this objectively-defined risk . . . was either
    known or so obvious that it should have been known.” In
    re Seagate Tech., LLC, 
    497 F.3d 1360
    , 1371 (Fed. Cir.
    2007). Since the District Court’s decision, the Supreme
    Court issued Halo Electronics, which rejected the re-
    quirement of “finding . . . objective recklessness in every
    case before district courts may award enhanced 
    damages.” 136 S. Ct. at 1932
    . Now, “[t]he subjective willfulness of a
    patent infringer, intentional or knowing, may warrant
    enhanced damages, without regard to whether his in-
    fringement was objectively reckless.” 
    Id. The Supreme
    Court has made it clear that awards of
    enhanced damages are discretionary, and “courts should
    continue to take into account the particular circumstances
    of each case in deciding whether to award damages, and
    in what amount.” 
    Id. When deciding
    how much to award
    in enhanced damages, district courts often apply the non-

    B. The District Court Did Not Err in Its Willfulness
    Finding or Award of Enhanced Damages
    Holland argues that this court should reverse the
    finding of willful infringement and the award of enhanced
    damages because (1) there is no evidence to suggest that
    Holland knew of the ’329 patent before the start of this
    litigation; (2) there is no evidence to suggest that Holland
    had access to the technical algorithms used in the ’329
    patent, such that willful copying would be impossible;
    (3) it is undisputed that Holland was not involved in
    development of the Rail Vision Systems software; and
    (4) Holland processes its data using different software
    algorithms than those in the ’329 patent. Appellant’s
    Br. 58−61.
    6  The Read factors consider (1) “whether the in-
    fringer deliberately copied the ideas of another”;
    (2) “whether the infringer, when he knew of the other’s
    patent protection, investigated the scope of the patent and
    formed a good-faith belief that it was invalid or that it
    was not infringed”; (3) “the infringer’s behavior as a party
    to the litigation”; (4) the “[d]efendant’s size and financial
    condition”; (5) the “[c]loseness of the case”; (6) the
    “[d]uration of the defendant’s misconduct”; (7) “[r]emedial
    action by the defendant”; (8) the “[d]efendant’s motivation
    for harm”; and (9) “[w]hether the defendant attempted to
    conceal its 
    misconduct.” 970 F.2d at 827
    (footnote and
    citations omitted).
    GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.            25
    Substantial evidence supports the jury’s finding that
    subjective recklessness led to willful infringement in this
    case. The jury heard evidence that Holland was aware of
    the ’329 patent prior to the current litigation, see, e.g.,
    J.A. 1180−87, 1340, 1384−85; see also J.A. 1161−62, 1277,
    and believed that it was infringing the patent. Evidence
    to support this latter proposition included evidence of the
    parties’ prior business dealings from which the jury could
    have inferred that Holland believed that it needed to
    acquire or license Georgetown’s Aurora System to avoid
    infringement, see, e.g., J.A. 1187−88, and “circumstantial
    evidence that Holland copied [Georgetown’s] technology,”
    Georgetown Rail II, 
    2016 WL 3346084
    , at *17. Although
    Holland continues to dispute several of these facts, the
    jury was free to decide whose evidence it found more
    compelling on the question of willfulness and found in
    Georgetown’s favor. Lighting Ballast 
    Control, 790 F.3d at 1342
    . We will not disturb that finding here, where sub-
    stantial evidence supports the jury’s conclusions. See 
    id. As for
    enhanced damages, on this record, we cannot
    conclude that the District Court abused its discretion in
    weighing the evidence or applying the Read factors. See
    i4i Ltd. 
    P’ship, 598 F.3d at 858
    . Holland makes no specif-
    ic arguments with respect to the District Court’s applica-
    tion of the Read factors in its Opening Brief. See
    generally Appellant’s Br. In its Reply Brief, Holland
    states that the same arguments it makes to reverse the
    finding of willfulness go to certain Read factors, without
    directly connecting its arguments to individual Read
    factors. Reply Br. 28.
    None of the arguments Holland makes with respect to
    the findings of enhanced damages demonstrate abuse of
    discretion by the District Court. The District Court made
    detailed factual findings which, taken together, support
    its award of enhanced damages. It did not merely look at
    the jury’s finding of willfulness; rather, it applied and
    considered all nine Read factors. Specifically, after ana-
    26              GEORGETOWN RAIL EQUIP. CO.   v. HOLLAND L.P.
    lyzing each Read factor individually, the District Court
    stated that “[f]actors 1, 2, and 5 support enhancement;
    factors 3, 4, and 7 slightly support enhancement; and
    factors 6, 8, and 9 are neutral.” Georgetown Rail II, 
    2016 WL 3346084
    , at *21. It also found that “no single factor
    weighs against enhancement.” 
    Id. Finally, the
    District
    Court took into account the degree of willfulness and
    found that it was “not warranted” to enhance damages to
    the full maximum statutory amount of treble damages
    (over $4,500,000); rather, it awarded only an additional
    $1,000,000. 
    Id. Considering all
    of the Read factors and
    the District Court’s statutory authority to treble damages
    under § 284, the award of $1,000,000 in addition to the
    damages award of $1,544,333 was not an abuse of discre-
    tion.
    CONCLUSION
    We have considered the parties’ remaining arguments
    and find them unpersuasive. Accordingly, the Final
    Judgment of the U.S. District Court for the Eastern
    District of Texas is
    AFFIRMED
