 2                  VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 Before PROST, Chief Judge, BRYSON and WALLACH, Circuit
                         Judges.
 BRYSON, Circuit Judge.
     Following trial, a jury in the United States District
 Court for the District of Delaware found that defendants
 GlaxoSmithKline LLC and Glaxo Group Limited (collec-
 tively, “GSK”) infringed U.S. Patent No. 8,303,991 (“the
 ’991 patent”), owned by plaintiff Vectura Limited, and that
 the patent was not invalid. The district court denied GSK’s
 post-trial motions for judgment as a matter of law and a
 new trial. GSK now appeals from the judgment against it.
 We affirm.
                               I
                              A
     Vectura filed this action in 2016, alleging that GSK had
 directly and vicariously infringed various claims of the ’991
 patent. Vectura later narrowed its infringement case to al-
 lege only direct infringement of claim 3 of the patent.
     The ’991 patent concerns the production of “composite
 active particles” for use in pulmonary administration, such
 as in dry-powder inhalers. The composite active particles
 described in the patent consist of additive material that is
 adhered to particles of active ingredient. ’991 patent, col.
 11, ll. 48–55. The active ingredient produces the desired
 chemical or biological effect, while the additive particles
 promote the dispersion and delivery of the active ingredi-
 ent into the lungs when the inhaler is activated. Id. at col.
 10, ll. 6–16.
     The specification of the ’991 patent first discloses a
 method for adhering additive material to the active ingre-
 dient. The method entails milling solid active particles in
 the presence of solid additive particles with sufficient en-
 ergy to break down coarse particles into fine particles, re-
 sulting in the additive particles smearing over, and fusing

 onto, the active particles. Id. at col. 2, line 4, through col.
 3, line 8. The specification also discloses various composite
 particles that are created by the disclosed milling method.
Id. at col. 11, ll. 44–59; cols. 13–15. The specification con-
 tains a list of additive materials that promote pulmonary
 dispersion and are compatible with its milling method. Id.
 at col. 8, line 62, through col. 10, line 52. Magnesium stea-
 rate is one of the additive materials discussed in the speci-
 fication. Id. at col. 10, ll. 4–5.
     The claims of the ’991 patent cover the composite active
 particles, not the milling method. Apparatus claim 1 reads
 as follows:
     1. Composite active particles for use in a pharma-
     ceutical composition for pulmonary administra-
     tion, each composite active particle comprising a
     particle of active material and particulate additive
     material on the surface of that particle of active
     material, wherein the composite active particles
     have a mass median aerodynamic diameter of not
     more than 10 μm, and wherein the additive mate-
     rial promotes the dispersion of the composite active
     particles upon actuation of a delivery device.
     Claim 2 depends from claim 1 and requires the additive
 material to include one or more of certain compounds, one
 of which is “a metal stearate or derivative thereof.” Claim
 3 depends from claim 2 and requires the additive material
 to be magnesium stearate.
                               B
     In the district court, Vectura alleged infringement by
 GSK’s Ellipta-brand inhalers: the Breo, Anoro, and Incruse
 devices. Each of the accused inhalers features one or more
 “blisters,” which are sealed receptacles containing a single
 active ingredient, an excipient, and, optionally, additive
 material. The blisters use magnesium stearate as the ad-
 ditive material and lactose as the excipient. As for the
Case: 20-1054    Document: 54      Page: 4    Filed: 11/19/2020

 4                  VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 active ingredients, the blisters contain one of three drugs—
 vilanterol, umeclidinium, or fluticasone.
     The Breo inhaler features two blisters. The first con-
 tains a mixture of vilanterol, lactose, and magnesium stea-
 rate. The second contains a mixture of fluticasone and
 lactose, but not magnesium stearate.
     The Anoro inhaler also features two blisters. The first
 contains a mixture of vilanterol, lactose, and magnesium
 stearate. The second contains a mixture of umeclidinium,
 lactose, and magnesium stearate.
     The Incruse inhaler features only one blister. That
 blister contains a mixture of umeclidinium, lactose, and
 magnesium stearate.
     In preparing the mixtures containing magnesium stea-
 rate, GSK uses a multi-step mixing process. GSK first
 mixes the lactose excipient with magnesium stearate in the
 absence of the active ingredient. That step yields lactose
 particles that are discontinuously coated with magnesium
 stearate. After a de-lumping step, GSK then mixes the lac-
 tose particles with the active ingredient. In that step,
 small particles of the active ingredient are deposited onto
 the larger lactose particles, which are already coated with
 small particles of magnesium stearate.
                              C
     The district court construed various claim terms in the
 ’991 patent, two of which are relevant to this appeal. First,
 the court construed the phrase “promotes the dispersion of
 the composite active particles” (the dispersion limitation)
 to mean “wherein a composition that contains one or more
 composite active particles has increased dispersion of the
 active material upon activating a delivery device for inha-
 lation into the lungs by a patient, as compared to the same
 composition wherein unmodified active particles are sub-
 stituted for the composite active particles.” Vectura Ltd. v.

 GlaxoSmithKline LLC, No. 1:16-CV-00638, 2018 WL
4700222, at *9 (D. Del. Oct. 1, 2018).
      Second, the court construed the term “composite active
 particles.” GSK’s proposed construction of that term in-
 cluded a process limitation requiring that the composite ac-
 tive particles be “formed by milling . . . using sufficient
 energy and duration to ensure sufficient break-up of ag-
 glomerates of both constituents, dispersal, and even distri-
 bution of additive over the active particles.” Id. at *2. The
 district court rejected GSK’s proposed construction, hold-
 ing that the term “composite active particles” does not in-
 clude a process limitation. Id. at *3–8. The court construed
 the term to mean “[a] single particulate entit[y/ies] made
 up of a particle of active material to which one or more par-
 ticles of additive material are fixed such that the active and
 additive particles do not separate in the airstream.” Id. at
 *8.
     At trial, Vectura’s infringement theory focused on the
 vilanterol and umeclidinium mixtures in the accused inhal-
 ers. Vectura presented evidence that those mixtures con-
 tain active particles coated with magnesium stearate, i.e.,
 composite active particles, even though GSK’s multi-step
 process does not mix the active ingredient and the magne-
 sium stearate in isolation, but instead mixes them in the
 presence of lactose.
     Vectura prevailed on the issues of validity, infringe-
 ment, and willful infringement. The jury awarded Vectura
 a royalty of 3% on a royalty base of $2.99 billion in sales for
 the accused inhalers, which resulted in an award of
 $89,712,069 in damages for the period of infringement end-
 ing in December 2018.
     Following the jury’s verdict, GSK moved for judgment
 of noninfringement as a matter of law or, alternatively, a
 new trial on infringement. GSK argued that Vectura pre-
 sented insufficient evidence to support the jury’s implied
 finding that the accused inhalers satisfy the dispersion

 6                  VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 limitation. GSK also moved for a new trial on damages.
 GSK argued that Vectura’s damages theory was legally
 flawed and that Vectura’s counsel made prejudicial com-
 ments that affected the jury’s damages award. The district
 court denied GSK’s post-trial motions, Vectura Ltd. v. Glax-
 oSmithKline LLC, 397 F. Supp. 3d 579, 596 (D. Del. 2019),
 and GSK appealed to this court.
                               II
     On appeal, GSK raises four issues: First, GSK argues
 that it is entitled to judgment of noninfringement as a mat-
 ter of law because Vectura failed to present substantial ev-
 idence that the accused inhalers use additive material that
 “promotes the dispersion” of the active material. In the al-
 ternative, GSK requests a new trial on infringement. Sec-
 ond, GSK argues that the district court’s construction of
 the term “composite active particles” was erroneous, re-
 quiring a new trial on infringement. Third, GSK argues
 that it is entitled to a new trial on damages because of flaws
 in the calculation of the royalty proposed by Vectura’s dam-
 ages expert. Fourth, GSK argues that it is entitled to a new
 trial on damages because Vectura made prejudicial refer-
 ences to GSK’s sales and advanced an improper “pennies
 on the dollar” argument in comparing Vectura’s royalty re-
 quest to GSK’s sales.
     The denial of a motion for judgment as a matter of law,
 an issue not unique to patent law, is governed by the re-
 gional circuit’s standard of review. Personalized User
 Model, LLP v. Google Inc., 797 F.3d 1341, 1345 (Fed. Cir.
 2015). Under Third Circuit law, a district court must grant
 judgment as a matter of law if a jury’s verdict is not sup-
 ported by substantial evidence, i.e., if “the record is criti-
 cally deficient of the minimum quantum of evidence from
 which the jury might reasonably afford relief.” Gomez v.
 Allegheny Health Servs., Inc., 71 F.3d 1079, 1083 (3d Cir.
 1995).

 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC                   7

     This court is also bound by the Third Circuit’s applica-
 tion of an “abuse of discretion” standard for reviewing the
 denial of a motion for new trial. Union Carbide Chems. &
 Plastics Tech. Corp. v. Shell Oil Co., 308 F.3d 1167, 1182
 (Fed. Cir. 2002) (citing Greenleaf v. Garlock, Inc., 174 F.3d
352, 363 (3d Cir. 1999)). Under Third Circuit law, a district
 court should grant a new trial only if the jury’s verdict is
 against the great weight of evidence and either is a miscar-
 riage of justice or cries out to be overturned. Leonard v.
 Stemtech Int’l Inc., 834 F.3d 376, 386 (3d Cir. 2016).
                              A
     The parties agree that, under the district court’s con-
 struction of the dispersion limitation, Vectura needed to
 prove that the use of magnesium stearate in the accused
 inhalers improves the dispersion of the active ingredient
 compared to identical products in which only the lactose
 excipient is coated with magnesium stearate. GSK argues
 that there was no substantial evidence of infringement as
 to that limitation because Vectura staked its case on a de-
 fective scientific test. That test, referred to as “Study 2,”
 was a GSK study in which GSK examined the dispersion
 rates of experimental blends of vilanterol, magnesium stea-
 rate, and lactose.
     The principal flaw in GSK’s argument is that Vectura
 did not rely solely on Study 2 to prove that the accused in-
 halers satisfy the dispersion limitation. Vectura intro-
 duced other evidence on dispersion as well. We first
 address GSK’s criticisms of Study 2 and then turn to the
 other evidence introduced by Vectura.
     Study 2 included a total of six blends of lactose and vi-
 lanterol particles. In blend 5, the lactose particles were
 coated with magnesium stearate, but the vilanterol parti-
 cles were uncoated. In blend 6, both the lactose particles
 and the vilanterol particles were coated with magnesium
 stearate. Study 2’s results showed that blend 6 produced
 better dispersion than blend 5, thus appearing to support

 8                 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 Vectura’s infringement theory on dispersion, at least as to
 the accused inhalers containing vilanterol mixtures.
     At trial, GSK sought to discount Study 2 as evidence of
 infringement. First, GSK introduced evidence that blend 5
 was a flawed control due to its poor content uniformity.
 GSK pointed to a statement in the report on Study 2 that
 the low dispersion in blends in which magnesium stearate
 had been used to coat the lactose but not the active drug
 was likely due to poor content uniformity and that drawing
 conclusions regarding dispersion “is not possible for those
 blends.” J.A. 6194. Second, GSK argued that it was im-
 proper for Vectura to extrapolate from Study 2 to the ac-
 cused inhalers in light of the differences between the
 mixing processes used to prepare the blends in Study 2 and
 the processes used to prepare the blends in the accused in-
 halers. Finally, GSK contended that Study 2 was irrele-
 vant to the umeclidinium mixtures in the accused inhalers
 because Study 2 tested only vilanterol mixtures.
     While Study 2 was not a perfect model for GSK’s com-
 mercial products, the authors of the report on Study 2 con-
 cluded that coating all components with magnesium
 stearate “produced a blend with a stable high FPF,” i.e., a
 high degree of dispersion, and that when the active drug is
 coated with magnesium stearate, “better uniformity has
 been observed.” J.A. 6193. From that evidence and the
 testimony of the experts at trial, the jury could conclude
 that despite its drawbacks, Study 2 generally supported
 the view that coating the active ingredient with magne-
 sium stearate improves dispersion of the active ingredient.
     As to whether Study 2 provides any support for Vec-
 tura’s claim of infringement as to the blisters containing
 only umeclidinium, the record contained evidence that vi-
 lanterol and umeclidinium behave similarly when coated
 with magnesium stearate. See, e.g., J.A. 1324. On this rec-
 ord, if the jury credited the results of Study 2 regarding
Case: 20-1054      Document: 54     Page: 9     Filed: 11/19/2020

 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC                      9

 vilanterol, it could reasonably have extrapolated those re-
 sults to umeclidinium.
     More fundamentally, regardless of any infirmities in
 Study 2 as evidence for the dispersion limitation, there was
 ample other evidence at trial indicating that coating vilan-
 terol with magnesium stearate and coating umeclidinium
 with magnesium stearate improves the dispersion of both
 active ingredients. That evidence included testing evi-
 dence and testimony from Vectura’s infringement expert
 and employees of both Vectura and GSK, as well as numer-
 ous documents relating to GSK’s work on dry-powder-in-
 haler formulations.
     Vectura’s witnesses testified that coating active ingre-
 dient particles with magnesium stearate helps overcome
 the tendency of the particles to stick together and therefore
 increases the dispersion of the particles in the lungs. J.A.
 1151–54. Evidence of tests conducted on coated and un-
 coated active-ingredient particles showed that coating the
 active particles substantially increased the dispersion of
 the active-ingredient particles and thus the amount of the
 active ingredient that could be delivered deep into the
 lungs. J.A. 1154–55. Tests run on GSK’s products showed
 that the particles of vilanterol and umeclidinium were con-
 sistently associated with magnesium stearate. J.A. 1201–
 04, 1208–12. And a GSK employee who was involved in
 testing GSK products acknowledged that the presence of
 magnesium stearate in the GSK products has the effect of
 increasing the fine particle mass of vilanterol, i.e., increas-
 ing the dispersion of the drug. J.A. 1426–27. 1
    Vectura also relied on GSK’s own documents as evi-
 dence that GSK’s products satisfy the dispersion

     1   The evidence showed that “fine particle mass,”
 “fine particle fraction,” and “fine particle dose” are all indi-
 cators of dispersion. See J.A. 1295–96, 1426–27, 1593–94.
Case: 20-1054    Document: 54      Page: 10     Filed: 11/19/2020

 10                  VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 limitation. A 2013 GSK report documenting the “current
 understanding associated with the use of magnesium stea-
 rate as a stabilising excipient” in vilanterol dry-powder-in-
 haler formulations relied on a finding that coating the
 active particles with magnesium stearate “provided better
 drug delivery in giving higher fine particle dose [(i.e., dis-
 persion)] than coating the matrix particles.” J.A. 1259–62,
 1292–95, 5008, 5013–14. Vectura’s expert testified that
 the recited portion of the GSK report meant that “coating
 the drug particles give[s] better dispersion than coating the
 matrix particles [(i.e., in this context, the lactose parti-
 cles)].” J.A. 1295. Based on the physical tests of GSK’s
 products, GSK’s documents, and his own analysis, the ex-
 pert concluded that coating the active ingredients in GSK’s
 products with magnesium stearate “would promote disper-
 sion of the composite active particle.” J.A. 1350.
     Another GSK document, directed to the use of magne-
 sium stearate as an excipient in the Ellipta inhalers,
 acknowledged that magnesium stearate, which acts to coat
 inhalation powder particles, tends to “physically stabilize
 the aerodynamic particle size distribution of the active in-
 gredient.” J.A. 5001. It does so, the document explained,
 by coating particles, thereby “reduc[ing] interparticle inter-
 actions.” Id. Vectura’s expert explained that reducing in-
 teractions between the particles improves particle
 dispersion. J.A. 1297–98.
      GSK’s documents also established that the active in-
 gredient becomes coated with magnesium stearate in
 GSK’s mixing process, and that magnesium stearate when
 mixed with the lactose and the drug substance in GSK’s
 products “tends to coat drug substance and the lactose.”
 J.A. 1309–13 (referencing documents at J.A. 5020 and
 5562). The addition of the magnesium stearate, according
 to those documents, aids “chemical stability and/or physi-
 cal (i.e., Fine Particle Dose) stability.” J.A. 5025 (referring
 to products containing umeclidinium); J.A. 5566 (referring
 to products containing vilanterol).          Vectura’s expert
Case: 20-1054    Document: 54      Page: 11    Filed: 11/19/2020

 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC                   11

 explained that fine particle dose “is how much drugs go into
 the lungs. So it’s a measure of the dispersion.” J.A. 1312;
 see also J.A. 1313–15.
     In sum, substantial evidence supported the jury’s im-
 plied finding that the accused inhalers satisfy claim 1’s dis-
 persion limitation.
                               B
     GSK next challenges the district court’s construction of
 the claim term “composite active particles.” GSK contends
 that the court should have construed that term to require
 that the composite particles be produced by the “high-
 energy milling” process referred to in the specification.
     To support its argument, GSK relies on two pieces of
 intrinsic evidence. First, GSK points to various passages
 in the ’991 specification that describe high-energy milling.
 According to GSK, those passages indicate that the dis-
 closed milling method is essential to the claimed composite
 active particles.
     Second, GSK looks to the ’991 patent’s prosecution his-
 tory and in particular an April 2012 response to an office
 action in which the applicants distinguished a prior art ref-
 erence to Bosch et al. GSK argues that the applicants dis-
 tinguished Bosch on the ground that Bosch’s wet-mixing
 processes were different from the “aggressive milling pro-
 cedure” recited in the application. For that reason, GSK
 argues, the applicants clearly disclaimed mixing processes
 other than high-energy milling, confirming that the term
 “composite active particles” should be construed to include
 a process limitation.
     Because GSK challenges the district court’s claim con-
 struction based only on intrinsic evidence, this court ap-
 plies de novo review. See Teva Pharm. USA, Inc. v. Sandoz,
 Inc., 574 U.S. 318, 332 (2015).
Case: 20-1054     Document: 54      Page: 12    Filed: 11/19/2020

 12                  VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

      At the outset, Vectura argues that GSK waived its
 claim construction challenge by proposing a different con-
 struction in the district court. We disagree. The construc-
 tion that GSK proposed to the district court required that
 the composite particles be crafted by “milling . . . using suf-
 ficient energy and duration to ensure sufficient break-up of
 agglomerates of both constituents, dispersal, and even dis-
 tribution of additive.” Vectura, 2018 WL 4700222, at *2.
 In support of that construction, GSK argued that the in-
 trinsic evidence established that “‘composite active parti-
 cles’ must be defined by how the particles are made—by a
 high energy milling process.” J.A. 10359. GSK makes the
 same argument to this court. See Appellants’ Opening Br.
 53 (“Vectura disclaimed processes for making ‘composite
 active particles’ other than high-energy milling.”). Also, as
 in its proposed construction, GSK asserts that the inherent
 milling process must be “capable of breaking coarse parti-
 cles . . . down to fine particles” by “appl[ying] a sufficiently
 high degree of force or energy to the particles.” See id. at
 53–54 (quoting the ’991 patent) (ellipses in original). Given
 the similarities between GSK’s arguments here and in the
 district court, we find no waiver.
     As to the merits of GSK’s claim construction argu-
 ments, this case falls between two prior cases from this
 court: Continental Circuits LLC v. Intel Corp., 915 F.3d 788
 (Fed. Cir. 2019), and Andersen Corp. v. Fiber Composites,
 LLC, 474 F.3d 1361 (Fed. Cir. 2007). In Andersen, we con-
 strued an apparatus claim to include a process limitation.
474 F.3d at 1373–74, 1377. In Continental Circuits, we de-
 clined to import a process limitation into an apparatus
 claim. 915 F.3d at 799–800. In both cases, we recognized
 that “process steps can be treated as part of the product
 claim if the patentee has made clear that the process steps
 are an essential part of the claimed invention.” Continen-
 tal Circuits, 915 F.3d at 799 (quoting Andersen, 474 F.3d
 at 1375). In both cases, as here, the accused infringers ar-
 gued that the patent’s specification made it clear that a
Case: 20-1054     Document: 54       Page: 13      Filed: 11/19/2020

 VECTURA LIMITED    v. GLAXOSMITHKLINE LLC                       13

 process was an essential part of the apparatus claim and
 that the patent’s prosecution history confirmed that essen-
 tial role. See Continental Circuits, 915 F.3d at 796–99; An-
 dersen, 474 F.3d at 1371–75.
     In Andersen, we emphasized that the specification used
 “language of requirement, not preference,” when describ-
 ing the apparatus-producing process. 474 F.3d at 1372. In
 Continental Circuits, however, we found that the specifica-
 tion “merely indicate[d] a preference for using” the appa-
 ratus-producing process. 915 F.3d at 799. We considered
 the specification’s statements that the apparatus “can be
 carried out” by the disclosed process and that the process
 was merely “one technique for forming the [apparatus].”
Id. at 797.
      The specification of the ’991 patent is more like the
 specification in Continental Circuits than the specification
 in Andersen. Although the ’991 patent contains a few state-
 ments suggesting that its high-energy milling is required,
 see, e.g., col. 2, ll. 57–65, and col. 3, ll. 9–14, those state-
 ments are outweighed by the numerous statements indi-
 cating that high-energy milling is merely a preferred
 process. See, e.g., col. 3, ll. 15–25 (describing how high-en-
 ergy milling may not be required for smaller particles be-
 cause the short-range Van der Waals forces may be
 sufficient to ensure adhesion); col. 3, ll. 59–65, and col. 5,
 ll. 35–37 (naming “preferred methods”); col. 4, ll. 22–25
 (“Preferably, the milling step involves the compression of
 the mixture of active and additive particles . . . .”); col. 6, ll.
 38–57. Moreover, the fact that the ’991 patent criticizes
 other methods, see, e.g., col. 2, ll. 57–65, and col. 3, ll. 52–
 58, is not dispositive. See AstraZeneca LP v. Breath Ltd.,
 542 F. App’x 971, 976 (Fed. Cir. 2013) (“[M]ere criticism of
 a particular embodiment encompassed in the plain mean-
 ing of a claim term is not sufficient to rise to the level of
 clear disavowal.” (quoting Thorner v. Sony Comput. Entm’t
 Am. LLC, 669 F.3d 1362, 1366 (Fed. Cir. 2012)). We thus
 conclude that the specification of the ’991 patent does not

 14                 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 make its milling method an essential part of apparatus
 claim 1.
     We also reject GSK’s argument that the prosecution
 history requires “composite active particles” to be con-
 strued to include a process limitation. In Andersen, the ap-
 plicant distinguished the prior art based on the method
 used to produce the claimed product. 474 F.3d at 1373. We
 held that the applicant clearly disclaimed apparatuses pro-
 duced by the prior art’s methods, confirming that the appa-
 ratus claim should be construed to include a process
 limitation. Id. at 1373–74.
      In this case, the applicants distinguished the Bosch ref-
 erence on the ground that Bosch disclosed only “the appli-
 cation of surface modifier material that is in the liquid
 phase,” while the applicants’ claim recited active particles
 coated with “particulate additive material.” J.A. 10218–19.
 Thus, according to the applicants, Bosch involved “wet pro-
 cesses that involve dissolution of the surface modifier, or
 use of a liquid surface modifier, and subsequently forming
 a film over the active particle,” while “the composite parti-
 cles claimed in the present application do not comprise
 ‘coatings such as those formed by wet processes that re-
 quire dissolution of one or both components.’” J.A. 10220
 (quoting the patent application). The applicants added
 that Bosch “does not teach or suggest the milling of partic-
 ulate surface modifier with drug particles. Instead, the
 milling operations disclosed in the Bosch reference are per-
 formed with liquid phase surface modifier, in other words,
 surface modifier that is a liquid or is in solution.” Id. Be-
 cause Bosch teaches “the application of a film layer of sur-
 face modifier material by adsorption, which will produce a
 thin, uniform, continuous coating on the drug particles,” it
 does not “include particulate additive material on the sur-
 face of the active particles” and therefore “does not disclose
 the particles claimed in the present application.” J.A.
 10221.

      Although the applicants stated that the composite par-
 ticles “are fused to the active particle in a manner only pos-
 sible using an aggressive milling procedure,” J.A. 10218, 2
 that statement did not purport to add a process limitation
 to the apparatus claim. Instead, that statement merely
 sought to demonstrate that Bosch’s coated particles were
 necessarily different from the applicants’ coated particles
 because Bosch used a process that could not possibly pro-
 duce “particulate additive matter on the surface of [a] par-
 ticle of active material,” as required by the applicants’
 claim. Accordingly, the most reasonable interpretation of
 the April 2012 response is that the applicant distinguished
 Bosch based on the unique structure of the claimed compo-
 site particles, not the disclosed milling method. We there-
 fore reject GSK’s challenge to the district court’s claim
 construction.
                               C
     GSK argues that Vectura’s damages theory is legally
 flawed, leaving the jury’s award unsupported by the record.
 GSK requests a new trial on damages as a remedy. As ex-
 plained above, we review the district court’s denial of a new
 trial for an abuse of discretion.
     The parties have a licensing history. In 2010, Vectura
 granted GSK a non-exclusive, worldwide license to more
 than 400 patents, the sum of which covered GSK’s respira-
 tory therapeutics containing vilanterol and/or umec-
 lidinium. The centerpiece of the 2010 license was a now-
 expired Vectura patent with claims directed to coating lac-
 tose excipients with additive material such as magnesium
 stearate. The 2010 license also contained a non-assert

     2   See also J.A. 10222 (“These particles can only be
 produced using high energy milling processes to fuse and
 smear the additive particles on to the surface of the active
 particles.”).

 16                  VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 clause for Vectura patents that covered formulations con-
 taining magnesium stearate. The non-assert clause in-
 cluded the application that matured into the ’991 patent.
     The 2010 license featured a tiered royalty structure in
 which GSK would pay a royalty of 3% on its first 300 mil-
 lion British pounds in sales, 2% on sales between 300 mil-
 lion and 500 million pounds, and no additional royalties on
 sales above 500 million pounds. The 2010 license expired
 on July 25, 2016.
     At trial, Vectura presented a damages theory based on
 the 2010 license being a comparable license. Vectura’s
 damages expert, Kimberly J. Schenk, adopted the 2010 li-
 cense’s first-tier royalty rate (3%) as a flat royalty rate and
 the 2010 license’s royalty base (total sales of the licensed
 products) as her royalty base. Ms. Schenk declined to
 adopt the royalty cap from the 2010 license, citing changed
 circumstances by the time of the hypothetical negotiation,
 which would have occurred in July 2016 when the 2010 li-
 cense expired. GSK presented an alternative theory, also
 based on the total revenue produced by the licensed prod-
 ucts. Under GSK’s theory, however, the royalty rate would
 have been much lower, only 0.0187%.
      GSK argues that Vectura’s evidence was insufficient to
 support the jury’s damages award. GSK first attacks Ms.
 Schenk’s use of the total sales of the accused inhalers as
 her royalty base. GSK argues that, under this court’s prec-
 edents, Ms. Schenk needed to show that the patented vi-
 lanterol and umeclidinium mixtures drove consumer
 demand for the accused inhalers before presenting a dam-
 ages theory based on the entire market value of the accused
 inhalers. GSK contends that Ms. Schenk did not make
 such a showing and, as a result, she needed to apportion
 her royalty base to account for the non-infringing compo-
 nents in the accused inhalers, such as the fluticasone blis-
 ter in the Breo inhaler. Appellants’ Opening Br. 61 (citing

 Ericsson, Inc. v. D-Link Sys., Inc., 773 F.3d 1201 (Fed. Cir.
 2014)).
      The damages theories tried in this case present a ra-
 ther unusual circumstance. Ordinarily, an entire-market-
 value royalty base is appropriate only when the patented
 feature creates the basis for customer demand or substan-
 tially creates the value of the component parts, and appor-
 tionment is required when an entire-market-value royalty
 base is inappropriate. Virnetx, Inc. v. Cisco Sys., Inc., 767
F.3d 1308, 1326 (Fed. Cir. 2014). However, this court has
 explained that when a sufficiently comparable license is
 used as the basis for determining the appropriate royalty,
 further apportionment may not necessarily be required.
 See, e.g., Bio-Rad Labs., Inc. v. 10X Genomics Inc., 967 F.3d
1353 (Fed. Cir. 2020); Elbit Sys. Land & C4I Ltd. v. Hughes
 Network Sys., LLC, 927 F.3d 1292 (Fed. Cir. 2019); Com-
 monwealth Sci. & Indus. Rsch. Organisation v. Cisco Sys.,
 Inc., 809 F.3d 1295 (Fed. Cir. 2015). That is because a dam-
 ages theory that is dependent on a comparable license (or
 a comparable negotiation) may in some cases have “built-
 in apportionment.” See, e.g., Commonwealth, 809 F.3d at
 1303.
     This is one such case. Although GSK refers to the 2010
 license as being “purportedly comparable,” the evidence
 clearly supports Vectura’s contention that the 2010 license
 was sufficiently comparable for use in its damages calcula-
 tion. Indeed, GSK’s own damages expert, Dr. William
 Kerr, testified that the 2010 license was “a very close com-
 parable, much closer than you ever find in a patent case.”
 J.A. 1857–60.
     Built-in apportionment effectively assumes that the
 negotiators of a comparable license settled on a royalty rate
 and royalty base combination embodying the value of the
 asserted patent. Id. As the district court noted, a party
 relying on a sufficiently comparable license can adopt the
 comparable license’s royalty rate and royalty base without

 18                 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 further apportionment and without proving that the in-
 fringing feature was responsible for the entire market
 value of the accused product. Vectura, 397 F. Supp. 3d at
 593 (citing Commonwealth, 809 F.3d at 1301–04).
     That is what Ms. Schenk did when she adopted the roy-
 alty rate and royalty base that was used in the 2010 li-
 cense. To support Ms. Schenk’s damages theory, Vectura
 offered evidence that the circumstances of the 2010 license
 and the hypothetical negotiation in 2016 were highly com-
 parable and that principles of apportionment were effec-
 tively baked into the 2010 license. J.A. 1447–48; see Bio-
 Rad, 967 F.3d at 1373.
     We have cautioned that “district courts performing rea-
 sonable royalty calculations [must] exercise vigilance when
 considering past licenses to technologies other than the pa-
 tent in suit” and “must account for differences in the tech-
 nologies and economic circumstances of the contracting
 parties.” Virnetx, 767 F.3d at 1330. Here, GSK argues that
 even if the 2010 license is superficially comparable, Ms.
 Schenk failed to account for the technical and economic dif-
 ferences between the 2010 license and the hypothetical ne-
 gotiation that would have occurred when the 2010 license
 expired in 2016. GSK notes that the 2010 license encom-
 passed rights to more than 400 patents and that the royalty
 established in that license was subject to a cap for sales
 above a certain amount.
     Vectura introduced evidence, however, that the key
 component of the 2010 license was permitting GSK to use
 Vectura’s invention of coating lactose particles with mag-
 nesium stearate. The 2010 license and the hypothetical ne-
 gotiation thus cover “roughly very similar technologies,” as
 Ms. Schenk testified. J.A. 1448. Similarity of scope is con-
 firmed by the fact that the mixtures Vectura points to as
 infringing the ’991 patent would have been the very same
 mixtures covered by the 2010 license. On appeal, GSK has
 offered nothing to undermine that conclusion. Accordingly,
Case: 20-1054    Document: 54     Page: 19    Filed: 11/19/2020

 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC                  19

 the fact that other patents were included in the 2010 li-
 cense does not fatally undermine Ms. Schenk’s theory of
 comparability.
     Ms. Schenk also considered and rejected the argument
 that there were meaningful economic differences between
 the benefits of coating the lactose particles and coating the
 active ingredients. J.A. 1481–82. She also considered and
 rejected the suggestion that there were other technical or
 economic distinctions between the 2010 license and the
 2016 hypothetical negotiation that rendered them not com-
 parable. J.A. 1465–85. GSK cross-examined Ms. Schenk
 on those matters, and the disputes over that evidence were
 properly left for the jury to resolve. See Bio-Rad, 967 F.3d
 at 1374.
      GSK’s second line of attack focuses on the absence of a
 royalty cap in Vectura’s damages theory. GSK argues that
 if the 2010 license is truly a comparable license, it was im-
 proper for Ms. Schenk to discard the royalty cap while sim-
 ultaneously retaining the royalty rate and royalty base
 used in the 2010 license. For support, GSK asserts that
 the royalty cap was an integral part of the 2010 negotia-
 tions and that in 2016 Vectura had proposed an extension
 of the 2010 license that would have retained the royalty
 cap.
      Ms. Schenk testified that the assumption of validity
 and infringement in a hypothetical negotiation, among
 other changed circumstances, supported not including a
 cap on her proposed royalty. J.A. 1458, 1484. The jury was
 entitled to credit that testimony and to note that by 2016
 the accused inhalers had already become hugely success-
 ful, which would have increased Vectura’s leverage in the
 hypothetical negotiation. It was therefore permissible for
 the jury to credit Ms. Schenk’s testimony and to award
 damages without applying a royalty cap. In sum, the dis-
 trict court did not abuse its discretion in denying GSK’s
 motion for a new trial on damages.

                               D
      Finally, GSK contends that the district court should
 have ordered a new trial on damages because Vectura
 made improper references during the trial to GSK’s $3.8
 billion in U.S. sales for the accused inhalers. In particular,
 GSK complains that Vectura overemphasized GSK’s U.S.
 sales and made an improper “pennies on the dollar” argu-
 ment by framing its requested damages as small compared
 to those sales. Under Third Circuit law, a new trial is
 proper with respect to such claims if the appellee made
 prejudicial remarks and it is “reasonably probable” those
 prejudicial remarks influenced the jury’s verdict. Draper
 v. Airco, Inc., 580 F.2d 91, 97 (3d Cir. 1978).
     At the outset, Vectura argues that GSK waived its prej-
 udice arguments by not moving to bar Vectura from refer-
 ring to GSK’s total inhaler sales and by not making timely
 objections to those references during trial.
      The waiver issue is complicated by the unusual way
 that the evidentiary record developed at trial. In a motion
 in limine directed to the issue of sales, GSK requested that
 Vectura be prohibited from introducing evidence of GSK’s
 foreign sales, and the motion was granted. Notably, how-
 ever, GSK did not request that evidence of the volume of
 U.S. sales be prohibited. In fact, GSK admitted at trial
 that “under the agreement of the [motion in limine], the
 sales of the accused products come in. But global sales for
 GSK, global sales for the respiratory division, anything
 else are out.” J.A. 1464.
     Vectura referred to GSK’s U.S. sales of the accused in-
 halers twice during its opening statement and once during
 the direct testimony of Vectura’s corporate witness, all
 without objection from GSK. Not until Vectura elicited the
 amount of GSK’s sales during Ms. Schenk’s testimony on
 damages did GSK’s counsel object. Counsel claimed that it
 was improper for Ms. Schenk “to give an opinion on the en-
 tire market value of the product” without apportioning
Case: 20-1054    Document: 54     Page: 21    Filed: 11/19/2020

 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC                  21

 damages to the infringing features; that it was improper
 for her to rely on the 2010 license between Vectura and
 GSK “without apportioning between the value of the pa-
 tent-in-suit, and that license, and all other intellectual
 property rights that were obtained in that license”; and
 that she should not be allowed to “rely on the entire market
 value rule without addressing non-infringing alternatives.”
 J.A. 1429. Counsel also stated that it was “inflammatory
 to put billion dollar numbers in front of juries, and that
 should be avoided if at all possible.” J.A. 1430–31. Counsel
 added that it was inflammatory “to put up billion dollars
 on the screen, and then do the math from that, or worse to
 do what we heard a little bit in the opening of, and I expect
 to hear in closing, all we want is three percent of the bil-
 lions of dollars that GSK made.” J.A. 1435–36.
      The district court noted that GSK had not filed a pre-
 trial Daubert motion. See Daubert v. Merrell Dow Pharms.,
 Inc., 509 U.S. 579 (1993). For that reason, the court deter-
 mined that GSK had waived its general objections to Ms.
 Schenk’s built-in apportionment testimony and would be
 required to object to any particular question asked of her.
 However, the court made clear that it did not regard GSK
 as having waived its objection to the argument that “it’s
 just pennies on the dollar, so what’s the big deal?” The
 court added, “I don’t think the sales should be in any way
 emphasized beyond what is strictly required by the law. So
 if I hear that happening, I will make my own objection and
 I will sustain it because that should not be an argument.”
 J.A. 1437–40.
     Subsequently, Ms. Schenk provided testimony on dam-
 ages, in which she referred several times to GSK’s U.S.
 sales. GSK did not object to those references or to the
 demonstrative exhibits that included the dollar amount of
 those sales.
     During GSK’s case, its damages expert, Dr. Kerr, testi-
 fied that he thought Vectura’s three percent royalty rate
Case: 20-1054    Document: 54      Page: 22    Filed: 11/19/2020

 22                 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC

 was “holding GSK over a barrel.” J.A. 1886. On cross-ex-
 amination, Vectura’s counsel challenged that statement,
 saying, “so it’s your testimony that a three-percent royalty
 would be putting GSK over a barrel when they had $3 bil-
 lion worth of infringing product at stake?” J.A. 1887. At
 that point, the trial judge interceded, noting that he had
 said that he would police excessive references to the sales
 amounts. He added: “Let’s not talk any more about [the] 3
 billion figure.” J.A. 1888.
     There was no further reference at trial to the amount
 of GSK’s sales. Following the close of the evidence, the
 court instructed the parties not to refer to the overall sales
 figure during closing arguments. In his closing argument,
 Vectura’s counsel referred to GSK’s profits, but not the
 amount of its sales. GSK did not object to counsel’s closing
 argument.
      In its opinion on the motion for judgment as a matter
 of law and for a new trial, the district court found that Vec-
 tura had “repeatedly emphasized the amount of revenues
 made by Defendants and the relative smallness of the dam-
 ages award they were requesting,” and that its conduct in
 that regard was improper. Vectura, 397 F. Supp. 3d at 594.
 However, the court agreed with Vectura that, unlike in
 most cases in which there was no legitimate reason for the
 jury to hear large total revenue figures, in this case “there
 was no smallest salable patent-practicing unit, and the to-
 tal revenue was an appropriate base that the jury needed
 to hear to understand Plaintiff’s damages expert’s analy-
 sis.” Id. at 596. For that reason, the court concluded, “I do
 not find the introduction of the total revenue figure to be so
 prejudicial that the damages verdict ‘cries out to be over-
 turned.’” Id.
     With respect to the issue of waiver, the district court
 concluded that GSK had not waived its objections to the
 “pennies on the dollar” argument or to statements “empha-
 sizing [GSK’s sales] beyond what’s strictly required by the
Case: 20-1054    Document: 54      Page: 23    Filed: 11/19/2020

 VECTURA LIMITED   v. GLAXOSMITHKLINE LLC                   23

 law” in proving damages. J.A. 1439–40, 1888. We agree
 with the district court that although GSK may have waived
 its more general objections to Ms. Schenk’s damages testi-
 mony, it did not waive its objections to the “pennies on the
 dollar” argument or to statements unnecessarily emphasiz-
 ing GSK’s billion-dollar sales. The district court’s finding
 of no waiver is particularly well-founded in light of the
 court’s statement during trial that it would enter its own
 objection if it heard such arguments being made.
      We also agree with the district court that where Vec-
 tura made such arguments, they were improper. The dis-
 trict court pointed to three places in the trial record that
 Vectura made what the court considered to be the improper
 “pennies on the dollar” argument: during opening state-
 ment; during the cross-examination of Dr. Kerr; and in
 closing argument, where counsel referred to Vectura’s
 three percent royalty as “a small portion of GSK’s profits,
 which are in excess of 75 percent of its sales.” J.A. 2023. 3
      The district court was correct in not condemning the
 remaining references to GSK’s total U.S. sales because
 those remaining references were neither objected to nor ob-
 jectionable. They were not objectionable because it was
 necessary for Vectura to reference GSK’s total sales, either
 directly or indirectly, considering that Vectura’s damages
 theory asked the jury to multiply the three-percent royalty
 rate by the royalty base, i.e., GSK’s total sales. In particu-
 lar, it was legitimate for Ms. Schenk to reference GSK’s to-
 tal sales when calculating her proposed damages award
 because her royalty base was the total sales of the accused

     3   Notably, however, the remarks made by Vectura’s
 counsel in his opening statement, which were not objected
 to, occurred prior to the time the district judge announced
 that he would make his own objections to any references to
 GSK’s sales that were directed to the “pennies on the dol-
 lar” argument.
Case: 20-1054    Document: 54      Page: 24     Filed: 11/19/2020

 inhalers. As the district court noted, GSK did not attempt
 to prevent her from doing so with a motion in limine or a
 Daubert motion.
      It was also proper for Ms. Schenk to refer to the sales
 figures when analyzing the comparability of the 2010 li-
 cense and the 2016 hypothetical negotiation—an analysis
 critical to any built-in apportionment theory. She ex-
 plained that the 2016 negotiation, unlike the 2010 negoti-
 ation, featured certainty as to commercial success and
 profitability, considerations that bear on the eighth Geor-
 gia Pacific factor, “the commercial success and profitability
 of the accused products.” See Georgia-Pacific Corp. v. U.S.
 Plywood Corp., 318 F. Supp. 1116, 1120 (S.D.N.Y. 1970).
 Her references to GSK’s sales in that connection were
 therefore proper. See Bio-Rad, 967 F.3d at 1373–74; Fin-
 jan, Inc. v. Secure Computing Corp., 626 F.3d 1197, 1210
 (Fed. Cir. 2010) (rejecting defendant’s argument that its fi-
 nancial numbers from the years after the hypothetical ne-
 gotiation were irrelevant for purposes of the eighth Georgia
 Pacific factor). 4 The same is true of the brief reference to
 GSK’s sales by Vectura’s corporate representative, in the
 context of addressing the uncertainties surrounding the
 2010 negotiation relative to 2016. See J.A. 1108–09.
     After carefully surveying the remarks GSK identified
 as prejudicial, the district court found that the effect of the

      4   Ms. Schenk’s references to GSK’s sales do not suf-
 fer from the flaw found in the references to the defendant’s
 total sales in Uniloc USA, Inc. v. Microsoft Corp., 632 F.3d
1292 (Fed. Cir. 2011), relied on by GSK. In Uniloc, we held
 that the patentees’ using the defendant’s $19 billion in
 sales as a “check” on its proposed damages was “irrelevant
 and tainted the jury’s damages award.” 632 F.3d at 1318–
 21. Unlike in this case, the patentee’s damages theory in
 Uniloc did not depend on the use of the total amount of
 sales of the accused products. See id. at 1312.

 remarks that it found improper was not so prejudicial as to
 require a new trial. On the issue of the impact of improper
 conduct at trial, the views of the judge who supervised the
 trial proceedings are entitled to considerable weight. See
 Fineman v. Armstrong World Indus., Inc., 980 F.2d 171,
 207 (3d Cir. 1992) (“Because the trial judge was present
 and able to judge the impact of counsel’s remarks, we defer
 to his assessment of the prejudicial impact.”). We find no
 basis to second-guess the judgment of the experienced trial
 judge in this regard. We therefore decline to conclude that
 the district court abused its discretion, and we uphold the
 court’s decision denying a new trial on this ground.
                              III
     For the foregoing reasons, we affirm the district court’s
 post-trial order denying GSK’s motion for judgment of non-
