`
`INTRODUCTION
`
`GTP misquotes and mischaracterizes Dr. Stevenson’s opinions in an effort to exclude
`
`proper non-infringement analysis that applies the Court’s constructions, or the plain and ordinary
`
`meaning where appropriate, to the specific technology at issue. Despite arguing Dr. Stevenson
`
`improperly opined as to matters of law for non-infringement, GTP argues he should have opined
`
`as to a legal question for invalidity, namely the subsection of 35 U.S.C. § 102 under which each
`
`prior art system qualifies as such. GTP also mischaracterizes Dr. Stevenson’s invalidity opinions
`
`as incorrectly applying the law, yet GTP ignores the tables to Dr. Stevenson’s report in which he
`
`provides his detailed opinions. Because GTP has failed to meet its burden of proof on any ground
`
`presented in its motion, GTP’s motion should be denied in its entirety.
`
`II.
`
`ARGUMENT
`A.
`
`Dr. Stevenson did not attempt to construe the claims himself, but applied the
`Court’s constructions, including the plain meaning where applicable
`
`GTP attempts to distort Dr. Stevenson’s proper opinions concerning non-infringement, a
`
`question of fact, into improper claim construction in an effort to exclude his analysis. Medgraph,
`
`Inc. v. Medtronic, Inc., 843 F.3d 942, 949 (Fed. Cir. 2016) (“Infringement is a question of fact.”)
`
`(citation omitted); Network-1 Techs., Inc. v. Alcatel-Lucent USA, Inc., No. 6:11-CV-492-RWS-
`
`KNM, 2017 WL 4020591, at *5 (E.D. Tex. Sept. 13, 2017), objections overruled sub nom.
`
`Network-1 Techs., Inc. v. Hewlett-Packard Co., No. 6:13-CV-00072-RWS, 2017 WL 10222211
`
`(E.D. Tex. Nov. 7, 2017) (“Whether the accused products infringe under the Court’s claim
`
`construction is for the jury to decide.”). Dr. Stevenson explicitly states that he did not construe
`
`any term, but rather applied the Court’s constructions or the plain meaning of terms the Court did
`
`not construe:
`
`I have applied the Court’s constructions and the constructions
`agreed upon by the parties as part of the analysis for my Report. For
`
`-1-
`
`
`
`Case 2:21-cv-00040-JRG Document 169 Filed 12/22/21 Page 6 of 21 PageID #: 8142
`
`
`the terms that the Court did not construe or that the parties did not
`agree upon, I applied the plain and ordinary meaning of the term to
`a person of ordinary skill in the art.
`
`Ex. 1 ¶ 39; see also id. at ¶¶ 40-41. Dr. Stevenson’s discussion of intrinsic evidence to educate
`
`the jury on teachings of the Patents-in-Suit does not constitute impermissible claim construction,
`
`especially given that he continually ties his non-infringement analysis back to the claim language.
`
`This Court has found such testimony permissible. SSL Servs., LLC v. Citrix Sys., Inc., 940 F. Supp.
`
`2d 480, 492 (E.D. Tex. 2013), aff'd, 769 F.3d 1073 (Fed. Cir. 2014) (finding expert testimony
`
`concerning preferred embodiments in the specification in support of non-infringement opinions
`
`admissible because it “amounted to nothing more than an effort to educate the jury about the
`
`teachings of the ‘796 patent” and the expert “continually tie[d] [his] analysis back to the claim
`
`language”) (alterations added). It is hardly controversial in a patent case for an expert to refer to
`
`the specification or other intrinsic evidence to support his opinions on fact issues.
`
`The cases GTP cites simply reiterate that an expert cannot provide legal opinions such as
`
`construing a claim term, not that an expert is precluded from relying on any intrinsic evidence to
`
`support his non-infringement opinions. See CytoLogix Corp. v. Ventana Med. Sys., Inc., 424 F.3d
`
`1168, 1172-73 (Fed. Cir. 2005). For example, in the Apple v. Samsung case cited by GTP, the
`
`court declined to exclude an expert’s opinions that referenced the patent specification to support
`
`his understanding of a “video capture module.” Apple, Inc. v. Samsung Elecs. Co., Ltd., No. 12-
`
`CV-00630-LHK, 2014 WL 660857, at *5 (N.D. Cal. Feb. 20, 2014) (“Dr. Storer similarly notes
`
`(correctly) that ‘the specification only uses the term ‘video capture module’ in conjunction with
`
`‘video card.’”) (alteration in original). In EMC Corp. v. Pure Storage, the court precluded experts’
`
`testimony relying on the specification where it amounted to re-arguing claim construction and
`
`improperly “suggest[ed] that literal infringement can be established by a comparison between
`
`accused products and specification embodiments.” EMC Corp. v. Pure Storage, Inc., CV No. 13-

`
`1985-RGA, 2016 WL 775742, at *4 (D. Del. Feb. 25, 2016). Moreover, the court held that “the
`
`determination whetherthe testimony amounts to claim construction will have to be made on an
`
`objection by objection basis in the context of the trial.” Jd. Here, Dr. Stevenson doesnot rely on
`
`the specification “to narrow the plain meaning” of any term. Cf Salazar v. HTC Corp., No. 2:16-
`
`cv-01096-JRG-RSP, Dkt. 247 (E.D. Tex. Apr. 27, 2018) (Mot. Ex. A) at 4. Rather, as explained
`
`below, Dr. Stevenson used the specification and other intrinsic evidence only to educate the jury
`
`about the patented technologyasit pertains to his non-infringement opinions. Dr. Stevenson does
`
`not, and will not attempt to, construe any claim term.
`
`1.
`
`°431 Patent, Claim 7: “meansfor controlling a function of said
`apparatususing said information”
`
`GTP’s motion seeks to exclude the last three sentences of paragraph 105 andthe entirety
`
`of paragraph 106 of Dr. Stevenson’s non-infringement report. Mot. at 3. The opinions GTP seeks
`
`to exclude are simply Dr. Stevenson’s understanding of Mr. Occhiogrosso’s own position:
`
`
`
`Ex. 1 § 105 (emphasis in original). These opinions reflect Dr. Stevenson’s efforts to make sense
`
`of what unspecified “software and hardware” Mr. Occhiogrosso is relying on as corresponding
`
`structure for the recited “means for controlling.” Jd. Dr. Stevenson interprets Mr. Occhiogrosso’s
`
`tetht
`
`refers to the Figure 17 embodiment in the ’431 Patent and to GTP’s proposed construction for
`
`“means for controlling” in the Joint Claim Construction Statement merely to explain why “it is
`
`
`
`Case 2:21-cv-00040-JRG Document 169 Filed 12/22/21 Page 8 of 21 PageID #: 8144
`Case 2:21-cv-00040-JRG Document169 Filed 12/22/21 Page 8 of 21 PagelD#: 8144
`
`understandable”that Mr.Osshioso
`SS not to construe or limit any claim terms. Ex. 1 §§ 105-06. When askedin deposition
`
`which interpretation of “means for controlling” he applied, Dr. Stevenson confirmed he applied
`
`the Court’s construction rather than attempting to construe the claim himself:
`
`. Youstate in the second sentence, read that correctly?
`
`A. Yes.
`
`Q. Whatinterpretation of the claims are you using?
`
`A. The court’s.
`
`Ex. 2 at 145:15-146:4.! Dr. Stevenson’s opinions are simply interpreting Mr. Occhiogrosso’s own
`
`position in view of the surrounding evidence, and are not opinions regarding claim construction.
`
`Dr. Stevenson’s opinionsas to this limitation should not be excluded.
`
`2.
`
`°431 Patent, Claim 1: “determining from said sensed light the
`movementof said finger”
`
`GTP’s motion also seeks to exclude the second to last sentence of paragraph 98 of Dr.
`
`Stevenson’s non-infringement report as offering impermissible claim construction based on claim
`
`differentiation. GTP’s argument has no merit.
`
`Rather than construing the limitation, as GTP incorrectly asserts, Dr. Stevenson appliedits
`
`plain meaning, which requires “determining .
`
`.
`
`. the movement of said finger.” Dr. Stevenson
`
`explains that he seensedpro's
`
`' All emphases added unless otherwisestated.
`
`
`
`Case 2:21-cv-00040-JRG Document 169 Filed 12/22/21 Page 9 of 21 PageID #: 8145
`
`
`specifically points to how the accused products
`
`testimony of Samsung engineers that
`
`. See id. Dr. Stevenson
`
`
`
`
`
` Id. ¶ 99. He also cites to the
`
`
`
` Id. ¶ 98 (citing Cho. Tr. at 33:24-25).
`
`Thus, Dr. Stevenson applies the plain meaning of the claim terms, which require determining the
`
`movement of a finger, to the specific technology of the accused products, in a fact-driven non-
`
`infringement analysis that is well within the purview of a technical expert.
`
`Dr. Stevenson only uses Claims 5 and 6 as examples of how Claim 1 and its dependent
`
`claims consistently specify the movement of the fingers, not of a hand. See Ex. 1 ¶ 98. Dr.
`
`Stevenson does not use the scope of Claims 5 and 6 to limit the scope of Claim 1, but describes
`
`his understanding of “determining the movement . . . of said finger” in a way that neither limits
`
`nor endows additional meaning to the term. Id. at ¶¶ 96, 98; see Kraft Foods, Inc. v. Int’l Trading
`
`Co., 203 F.3d 1362, 1366-67 (Fed. Cir. 2000) (defining claim differentiation as a presumption that
`
`two claims of a patent are of different scope).
`
`It is GTP that is construing the claims. Despite Claim 1 expressly reciting determining the
`
`movement of a finger, GTP attempts to broaden the scope to include alternatively determining the
`
`movement of a hand. Not only did GTP fail to advance such a construction during Markman
`
`proceedings, but it is contrary to the plain language of the claim requiring determining movement
`
`of a finger. Claim 1 distinguishes a hand from the fingers, reciting “moving at least one finger in
`
`space . . .” while separately reciting “holding said device in one hand,” thereby conferring separate
`
`purposes and meanings to the two. In addition, the specification clearly distinguishes hands from
`
`-5-
`
`
`
`Case 2:21-cv-00040-JRG Document 169 Filed 12/22/21 Page 10 of 21 PageID #: 8146
`
`
`fingers. See, e.g., Ex. 3 (’431 Patent) at 22:25-30 (“. . . which through software determines the
`
`position of eyebrows, lips, hands, fingers . . .”); id. at 3:34-37, 11:2-6.
`
`Dr. Stevenson’s opinions regarding the term “movement of said finger” are an application
`
`of the plain meaning of the term to the specific technology of the accused products for purposes
`
`of a fact-based non-infringement analysis, not an attempt to construe any term as having a special
`
`meaning, and thus his opinions as to this limitation should not be excluded.
`
`3.
`
`’924 Patent, Claim 1: “a first camera oriented to view a user of the
`handheld device”
`
`GTP’s motion also seeks to exclude Dr. Stevenson’s opinions on this limitation based on
`
`misinterpretation of the Court’s Claim Construction Order. GTP argues the Court’s rejection of
`
`Defendants’ IPXL argument somehow amounts to a finding that the claims do not require the first
`
`camera to be looking at a user for it to be “oriented to view a user.” GTP’s selective quoting of
`
`the Court’s Order misses a key detail—the Court found Defendants’ argument that a user must use
`
`the device in a particular way for a camera to be “oriented to view a user” requires a configuration
`
`of the device rather than performance of an action by the user:
`
`Defendants’ argument that ‘[w]hether the camera is oriented to view
`a user cannot be determined until a user actually uses the device in
`a particular way’ is likewise unavailing. Defendants do not
`persuasively show that this requires performance of an action by the
`user rather than a configuration of the device.
`
`Dkt. 93 at 46. That is, the position in which the user places the device is part of the configuration
`
`of the camera, i.e., its orientation, not a method step. Thus, a camera in the claimed configuration
`
`is one that is placed in an orientation where it is looking at the user. This is further explained in
`
`Defendants’ pending motion for partial summary judgment. See Dkt. 140 at 14-17.
`
`Dr. Stevenson relied on the Court’s claim construction set forth in its Claim Construction
`
`Order. Ex. 1 ¶¶ 153-54, 157. Moreover, Dr. Stevenson explicitly stated that he was applying the
`
`-6-
`
`
`
`Case 2:21-cv-00040-JRG Document 169 Filed 12/22/21 Page 11 of 21 PageID #: 8147
`Case 2:21-cv-00040-JRG Document169 Filed 12/22/21 Page 11 of 21 PagelD #: 8147
`
`plain meaning of “oriented to view”: “The term ‘oriented to view’ byits plain meaning requires
`
`that the camera be currently lookingat or facing the user.” Ex. 1 § 155. That Dr. Stevenson applies
`
`the plain meaning1s further evident from the testimony of G7P’s technical expert, who agreed that
`
`a camera is not oriented to view until it is lookingat the user:
`
`
`
`Ex. 4 at 102:9-14.
`
`Dr. Stevenson does not use the specification to narrow the scope of the claim term orto
`
`limit the claim to an embodiment, but only to educate the jury about the teachings of the patent as
`
`they relate to Dr. Stevenson’s non-infringement opinions. There is nothing to warrant exclusion
`
`of his application of the plain meaning of “oriented to view” for purposes of non-infringement.
`
`See SSL Servs., 940 F. Supp. 2d at 492; Apple, 2014 WL 660857, at *5. GTP also mischaracterizes
`
`Dr. Stevenson’s opinions as based on “alleged disclaimer during prosecution,” even though Dr.
`
`Stevenson neverreferred to any such disclaimer. Dr. Stevenson refers to the applicant’s addition
`
`of the Figure 18 embodimentto the specification to overcome a written description rejection in
`
`order to identify the embodiment mostrelevant to the claims for purposes of educating the jury.
`
`Ex. 1 § 156. Dr. Stevenson never stated or opined that this should narrow the claims. Moreover,
`
`Dr. Stevenson tied his analysis of the accused products back to the claim language, not the
`
`specification. Jd. at § 159-61; SSZ Servs., 940 F. Supp. 2d at 492 (finding expert’s reliance on
`
`embodiments for non-infringement admissible wherehetied his analysis back to claim language).
`
`GTP’s mischaracterizations of the Court’s Claim Construction Order and Dr. Stevenson’s
`
`opinions are unavailing. Dr. Stevenson’s fact-based opinionsasto the “first camera oriented to
`
`-7-

`
`view a user of the handheld device” should not be excluded. Moreover, even if the Court were to
`
`find that Dr. Stevenson’s reference to intrinsic evidence constitutes improper claim construction
`
`despite the foregoing analysis, he shouldstill be permitted to testify regarding his understanding
`
`of the plain meaning of “oriented to view” without reference to such intrinsic evidence.
`
`4.
`
`°079 Patent: “light source”
`
`GTP’s motion further seeks to exclude Dr. Stevenson’s opinions asto the “light source”
`
`terms as applying a construction inconsistent with the Court’s Claim Construction Order. Dr.
`
`Stevenson, however, faithfully applied the Court’s plain meaning construction of these terms.
`
`First, Dr. Stevenson did not opine thatall displays are not light sources, nor did he apply
`
`Defendants’ rejected claim construction requiring that the light source be designed to directly
`
`illuminate the work volume or body part therein. Mot. at 4. Rather, Dr. Stevenson applied the
`
`plain meaning ofthe “light source” terms with respect to the accused products. GTP’s complaint
`
`boils down to faulting Dr. Stevenson for applying the express claim language:
`
`GTP’s Argument
`
`“Here use Dr.|Claim 1: “providingalight source adaptedto directagain, Defendants
`
`Stevenson in an attempt to contravene the|illumination through a work volume above the
`Court’s claim construction order.
`Dr.|
`light source”
`Stevenson opines that ‘the light source
`must be adapted to direct illumination|Claim 11: “a light source adapted to illuminate a
`throughthe work volumeor to illuminate|human bodypart within a work volume generally
`the human body part in the work|above the light source”
`
`volume.’” Mot. at 5-6.
`
`
`
`Claim 21: “providing a light source in fixed relation
`relative to the camera and adapted to direct
`illumination through the work volume”
`
`GTP also misquotes Dr. Stevenson’s opinions:

`
`“Moreover, Dr. Stevenson opines that the|“As explained in the ’431 Patent by the same

`Ex. B ¶ 211).
`
`source illumination everywhere except for on
`the object of interest.” Mot. Ex. B ¶ 211.
`
`
`Dr. Stevenson never construed the claims to require that the light source somehow overwhelm its
`
`own illumination. Rather, Dr. Stevenson explains the technological background of light sources
`
`and their use in determining gestures with reference to the specification, Ex. 1 ¶¶ 211-14, and how
`
`technology advanced such that light sources have become unnecessary for object recognition, id.
`
`¶ 215. Educating the jury about the background and development of the technology is well within
`
`the purview of a technical expert. SSL Servs., 940 F. Supp. 2d at 492; Network-1 Technologies,
`
`2017 WL 4020591, at *3. Dr. Stevenson further explained that the specification disclosures are
`
`consistent with his understanding of what was well-known in the art at the time of the invention,
`
`making clear he was not relying solely on the intrinsic evidence for his understanding of the
`
`technology, but also on his professional experience and extrinsic evidence. Ex. 1 ¶ 211.
`
`Dr. Stevenson further explained how the displays in certain accused products
`
`
`
`
`
`Ex. 1 ¶¶ 217-19. Dr. Stevenson thus concluded that these specific accused displays do not satisfy
`
`the plain language of the claims, which recite determination of “the gesture performed in the work
`
`volume and illuminated by the light source,” not that all displays can never satisfy the claims. Id.
`
`at ¶¶ 218-19. To the contrary, it is GTP’s efforts to exclude such permissible opinions concerning
`
`the specific accused display technology and related technological background that constitute
`
`improper, belated claim construction. GTP essentially argues that a display must necessarily
`
`constitute the claimed light source, contradicting the Court’s express finding that a display and a
`
`light source, while not mutually exclusive, are “not the same thing.” Markman Tr. at 40:14-20;
`
`Dkt. 93 at 34. There is no legitimate basis to exclude Dr. Stevenson’s opinions in this regard
`
`either. GTP’s motion should be denied.

`
`
`B.
`
`Dr. Stevenson was not required to provide a legal opinion by identifying the
`applicable subsection of 35 U.S.C. § 102 for prior art references he relied on
`for invalidity
`
`GTP complains that Dr. Stevenson did not identify the specific subsections of 35 U.S.C. §
`
`102 under which each prior art reference anticipates and/or renders obvious the Patents-in-Suit,
`
`with more specific complaints directed to the system prior art. Mot. at 6-7. These criticisms are
`
`misguided. The specific subsections of the Patent Act under which prior art anticipates and/or
`
`renders obvious a patent is a legal question reserved for the court. See Samsung Elecs. Co., Ltd.
`
`v. Infobridge Pte. Ltd., 929 F.3d 1363, 1369 (Fed. Cir. 2019) (“The ultimate question of whether
`
`a reference is prior art under § 102(b), however, is a legal question we review de novo.”) (citation
`
`omitted); EmeraChem Holdings, LLC v. Volkswagen Grp. of Am., Inc., 859 F.3d 1341, 1345 (Fed.
`
`Cir. 2017) (“Whether a reference qualifies as prior art under 35 U.S.C. § 103 is a legal question
`
`we review de novo.”) (citation omitted). Plainly, Dr. Stevenson is not a legal expert and cannot
`
`opine as this legal question. Dr. Stevenson testified that he relied on public demonstration of the
`
`prior art system as well as documents describing the system for invalidity of the asserted claims
`
`as laid out in his report, but that he could not provide the legal opinion as to how the system
`
`qualifies as prior art. Ex. 5 at 16:4-18:15, 19:12-20:20, 21:21-24:17.
`
`Defendants gave notice of the specific prior art subsections in their invalidity contentions,
`
`which GTP did not move to strike because they complied with the patent local rules. Ex. 6 at 27
`
`(“Defendants contend the following prior art uses, sales, and/or offers for sale anticipate or render
`
`obvious one or more Asserted Claims of the Asserted Patents under 35 U.S.C. 102(a) and/or (b)
`
`or 35 U.S.C. 103.”); see also id. at 22-26 (same for patents and printed publications). Nor did GTP
`
`move for summary judgment that any reference is not prior art under any subsection.
`
`Further, GTP’s allegation that it could potentially prove earlier conception and reduction
`
`to practice is baseless bordering on falsehood. In an interrogatory response, GTP alleged that Dr.

`
`
`Pryor, the named inventor of the Patents-in-Suit, “conceived the inventions a few months prior to
`
`the filings of” the provisional applications. Ex. 7 at 9. Defendants’ system prior art that GTP now
`
`challenges was available and publicly demonstrated more than a “few months” before the filing of
`
`the earliest provisional application in November 1998. Ex. 8 ¶¶ 166 (MDScope demonstrated in
`
`1997 or early 1998), 172 (MERL demonstrated around 1996). Moreover, Dr. Pryor testified that
`
`. Ex. 9 at 265:21-268:8, 274:23-
`
`275:25, 286:12-287:10, 295:8-25. GTP is thus unable to provide any corroborating evidence of
`
`conception whatsoever. Apator Miitors ApS v. Kamstrup A/S, 887 F.3d 1293, 1295 (Fed. Cir.
`
`2018) (referencing the “well established” law that a party seeking to establish conception through
`
`inventor testimony must proffer corroborating evidence). GTP’s representation that but for Dr.
`
`Stevenson’s alleged failings it could potentially “swear behind” lacks any credible basis.
`
`Moreover, GTP seeks to exclude Dr. Stevenson’s opinions under Daubert and Rule 702 of
`
`the Federal Rules of Evidence, but cites case law concerning Rule 26(a)(2)(C) of the Federal Rules
`
`of Civil Procedure. Mot. at 7 (“[F]ailure to comply with Rule 26 interefer[es] with attorney’s
`
`preparation”) (emphasis added); Carr v. Montgomery Cnty, No. H-13-2795, 2015 WL 5838862,
`
`at *4 (S.D. Tex. Oct. 7, 2015) (relating to defendants’ motion to exclude under Rule 26(a)(2)(C)
`
`for failure to properly designate an expert); id. Dkt. No. 51 at 2 (“These designations do not comply
`
`with Rule 26(a)(2)(C)”). These irrelevant cases cannot support GTP’s motion.
`
`C.
`
`Dr. Stevenson applied the correct legal standard when rendering his opinions
`regarding obviousness of the Asserted Method Claims2
`
` GTP incorrectly alleges that Dr. Stevenson failed to apply the proper legal standard for
`
`determining the obviousness of the Asserted Method Claims because he did not explicitly cite to
`
`
`2 Claims 1-3, 6, 14-22, 25-28 and 30 of the ’431 Patent, and Claims 1-6, 8-9, 21-25, 28, and 30 of
`the’079 Patent (collectively, “Asserted Method Claims”).

`
`
`the purported “standard of Parker Vision.” Mot. at 8 (citing ParkerVision, Inc. v. Qualcomm Inc.,
`
`903 F.3d 1354, 1363 (Fed. Cir. 2018)). ParkerVision merely reiterates that to demonstrate the
`
`obviousness of a method claim, it must be shown that a POSITA would have been motivated to
`
`combine teachings of the prior art references to achieve the claimed inventions with a reasonable
`
`expectation of success. ParkerVision, 903 F.3d at 1363. Dr. Stevenson states the same standard
`
`as provided by counsel: “An obviousness analysis involving two or more references or systems
`
`generally requires a reason why a POSITA in the relevant filed would have combined aspects of
`
`those references or systems in the way the Asserted Claims do.” Ex. 8 ¶ 32; see also id. ¶ 35.
`
`Whether Dr. Stevenson explicitly cited to the ParkerVision case is immaterial; he presented and
`
`followed the same standard in his obviousness analysis of the Asserted Method Claims.
`
`As supposed proof that Dr. Stevenson ignored the “Parker Vision standard,” GTP points
`
`solely to ¶¶ 258-260, 265-272 in the body of Dr. Stevenson’s report, which provides a summary
`
`of his prior art invalidity opinions. Inexplicably, GTP ignores the extensive tables attached to Dr.
`
`Stevenson’s report that provide his complete, detailed invalidity analysis, including with respect
`
`to obviousness. GTP marked these tables as exhibits in its deposition of Dr. Stevenson, yet here
`
`ignores them in seeking to strike the opinions they contain. That tactic is readily dismissed.
`
`In ParkerVision, the Federal Circuit found that Qualcomm failed to prove obviousness of
`
`certain method claims because it did not show that a POSITA would have been motivated to
`
`operate a prior art device to perform a claimed method step. 903 F.3d at 1363. Dr. Stevenson did
`
`the opposite. In the tables attached to his report, which GTP ignores, he repeatedly explains in
`
`detail why a POSITA would have been motivated to combine the prior art to perform the claimed
`
`steps of the Asserted Method Claims. See, e.g., Ex. 8 at Ex. E, p. 3 (“A POSITA would have been
`
`motivated to
