      “We have authority to determine whether to institute an inter partes review. 35 U.S.C. § 314(b) (2018); 37 C.F.R. § 42.4(a) (2025). An inter partes review may not be instituted “unless . . . the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). Upon institution of inter partes review, the review proceeds “on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a). Based on our consideration of the Petition, the Preliminary Response, and the evidence of record, we conclude that the information demonstrates a reasonable likelihood that Petitioner would prevail in showing the unpatentability of at least one of the Challenged Claims. Accordingly, we institute an inter partes review as to the Challenged Claims of the ’336 patent on all grounds asserted in the Petition.” slip op. at 2

Level of Ordinary Skill in the Art At this stage of the proceeding, there is no evidentiary dispute about the level of ordinary skill in the art.8 Based on the testimony of Mr. Crevelt, we determine that a person of ordinary skill in the art would have had at least a bachelor’s degree in computer science or computer engineering, with at least three years of experience in game development.

      “standard as would be used by a district court to construe a claim in a civil action involving the validity or infringement of a patent. 37 C.F.R. § 42.100(b). Under that standard, claim terms are given their ordinary and customary meaning, as would have been understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history of record. Id.; see also Phillips v. AWH Corp., 415 F.3d 1303, 1312–19 (Fed. Cir. 2005) (en banc); Thorner v. Sony Comput. Entm’t Am. LLC, 669 F.3d 1362, 1365–66 (Fed.

Petitioner argues that it is not necessary for us to provide an express construction for any claim term because the Petition “establishes the prior art meets each claim limitation under any reasonable construction.” Pet. 14–15. Patent Owner similarly submits that we “need not construe any terms at this stage, because under any reasonable construction of the claim terms, the prior art fails to disclose or suggest the claimed features.” Prelim.

      “an application filed September 20, 2010, that asserts the benefit of an application filed September 2, 2003. Ex. 1001, codes (22), (45), (54), (62). Petitioner asserts that the Challenged Claims of the ’336 patent “are entitled to an effective filing date of no earlier than September 2, 2003,” consistent with the date of the earliest application identified by the ’336 patent.9 See Pet. 7. For purposes of our analysis on the current record, in this Decision we apply September 2, 2003, as the priority date of the Challenged Claims. Walker was filed on May 1, 2003, and refers back to a provisional application filed on May 6, 2002, but Walker was not published until January 1, 2004. Ex. 1006, codes (22), (43), (60). Thus, Petitioner fails to show on the current record how, under pre–AIA 35 U.S.C. § 102(a), Walker discloses an invention that was described in a printed publication in this country before the invention thereof by the Patent Owner, because Walker was published after the applied priority date of the Challenged Claims of the’336 patent.” slip op. at 17

      “On July 16, 2025, the Acting Director issued her decision, which denied Patent Owner’s request for discretionary denial and referred this case to the Board. Paper 9, 3. The Decision stated “Petitioner provides persuasive reasoning, supported by evidence, that the Office erred in a manner material to the patentability of the challenged patents during patent examination, and, accordingly, discretionary denial under 35 U.S.C. § 325(d) is not appropriate.” Id. The Decision also stated “it is an appropriate use of Office resources to review the potential error.” Id. As stated in the Acting Director’s decision, “the Petitions [in IPR2025-00559; 00636] are referred to the Board to handle the cases in the normal course, including by issuing a decision on institution addressing the merits and other nondiscretionary considerations, as appropriate.” Id.

Therefore, at this stage of the proceeding, we need not reach Patent Owner’s assertions as to the third alternative argument and evidence Petitioner provides, namely the combination of examples 2), 3), and 4). For completeness, however, we acknowledge that Bucknell does not expressly combine examples 2), 3), and 4), mainly because example 4) only refers back to example 2). However, we note that from a plain reading of Bucknell’s written description it may not be a significant leap to understand that the disclosed combination of examples 2) and 4), with first and second portions 90 and 95 populated in reverse order as taught in example 4), that this combination could be subsequently modified by example 3) to provide a “second iteration . . . based on buffered data.” Ex. 1006 ¶¶ 26–27.

Conclusion as to Claim 1 In summary, we find Petitioner’s arguments and evidence sufficient to show a reasonable likelihood that claim 1 is unpatentable over Eckert in view of Bucknell and Lohr-1. On the current record, we find that Bucknell discloses “a first iteration” based on receiving the priority values for logical channels associated with the MAC-d flows. Ex. 1006 ¶ 26.

      “of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197.

      “Record evidence supports Petitioner’s contentions that a skilled artisan would have had reason to look to Kumar for further implementation details of a circuit that performs functions like those performed by Fujiyoshi. See Pet 24–26. For example, Dr. Young testifies that a person of ordinary skill in the art would have recognized that Kumar discloses the details, at a granular level, of Fujiyoshi’s capacitive sensing systems and would have looked to Kumar for understanding of how to implement Fujiyoshi’s system. Ex. 1002 ¶ 145. Patent Owner does not point to persuasive evidence to rebut this opinion. Moreover, Petitioner cites to Kumar, not only for an explicit disclosure of capacitive pickoff signals, but also for its disclosure of both DC bias and AC carrier signals and recognizing the applicability of an AC carrier pickoffs that operates without DC bias. Pet. 24–26 (citing Ex. 1005 3:65–4:2, 6:29–36). We credit Dr. Young’s testimony on this issue and agree with Petitioner that a person of ordinary skill in the art, looking at Fujiyoshi’s description of capacitive sensing systems, would be motivated to look to Kumar for its more detailed teachings of the implementation details of such systems and would combine these details to arrive at limitation 1(a). We determine that Petitioner has shown, by a preponderance of the evidence, that one of ordinary skill in the art would have been motivated to combine Fujiyoshi and Kumar in the manner argued by Petitioner.” slip op. at 37

Ex.1003, ¶¶34-37.

      “We find the District Court’s reasoning persuasive, and we, like the District Court, decline to adopt Petitioner’s overly broad proposed construction. However, for purposes of deciding the dispositive fact issue before us, we need not determine the precise boundaries of “surrounding textile structure,” for example whether it completely or mostly encircles the textile element, and if “mostly,” what percentage of encircling is required. See Pet. Reply 2 (Petitioner characterizing Patent Owner’s position as “mostly” means over 50%); id. at 4 (Petitioner impliedly arguing that the “surrounding” need not be complete, i.e., 100%); PO Sur-reply 3–4 (Patent Owner arguing that “Zuckerman’s textile structures . . . each abut only about 25% of the periphery of Zuckerman’s blank.”). We find that a person of ordinary skill in the art would not understand the portion of Zuckerman’s strip 13 in purple to surround the green blank 11 (textile element) under any reasonable construction of “surrounding textile structure.” Dr. Pastore testifies that “Zuckerman discloses two separate textile structures adjacent the blank—one on each side . . . they abut only two sides of Zuckerman’s blank, with each structure abutting only about a quarter of the blank’s periphery,” and opines that “a POSITA would not have understood these two separate structures, designated by purple in the figure above, to be a textile structure ‘surrounding’ the blank [shown in green].” Ex. 2003 ¶ 54. We find Dr. Pastore’s tesimony credible as it is consistent with Zuckerman’s Figure and with the plain and ordinary meaning of “surrounding” and with the Specification of the ’749 patent (particularly Figure 9). Dr. Brookstein’s testimony, on the other hand, is based on Petitioner’s overly broad proposed construction—that any part of a textile area that is not a textile element is “surrounding textile structure”—” slip op. at 44

      “We point out that in contrast with Patent Owner’s case law, the “indefinite article ‘a’ or ‘an’ in patent parlance usually carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising.’” KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed.

      “As discussed in section II.C.2 above, we interpret a “blade member” to have a cutting surface. Petitioner does not support adequately its assertion that Lint’s barbs 19 have a cutting surface. Petitioner acknowledges that Lint discloses “barb 19,” but Petitioner merely labels the barbs as blade members in annotated versions of Lint Figure 2. Pet. 21–22, 24. Petitioner’s witness, Dr. Kuhn, provides substantially identical testimony, also failing to explain how Lint’s barbs have a cutting surface or perform a cutting function. See Ex. 1019 ¶¶ 68, 70. Such conclusory assertions fail to satisfy Petitioner’s burden of persuasion. To the contrary of Petitioner’s assertions, Lint discloses that its barbs do not perform a cutting function. Lint discloses that its barbs retract to the closed position upon impact with an animal. Ex. 1002, 2:62–67. Only when the arrowhead has “completely penetrated the flesh of an animal” does the spring urge the barbs into the extended position “to retain the arrowhead within the animal.” Id. at 2:67–70.6 Lint discloses that its barbs provide 6 During the hearing, Petitioner’s counsel argued that Lint’s disclosure of its barbs deploying “[a]fter the arrowhead 10 has completely penetrated the flesh of an animal” means the spring urges the barbs forward after the resistance to the removal of the arrow from an animal (id. at 1:53–57, 2:67–70), but Lint does not disclose its barbs as performing any cutting function.

      “A claimed modification to the prior art may be an obvious design choice if the claimed structure performs the same function as in the prior art and it presents no novel or unexpected result over the prior art. See In re Kuhle, 526 F.2d 553, 555 (CCPA 1975) (finding that the use of the claimed feature “would be an obvious matter of design choice” when it “solves no stated problem” and “presents no novel or unexpected result” over the disclosed alternatives); Ex parte Maeda, Appeal No. 2010-009814, at 6–7 (PTAB Oct. 23, 2012) (informative) (“‘design choice’ may be appropriate where the applicant fails to set forth any reasons why the differences between the claimed invention and the prior art would result in a different function or give unexpected results” (citing In re Chu, 66 F.3d 292, 298–99 (Fed. Cir. 1995)). The ’177 patent explains that the purpose of the recited blade members is to maximize the cutting surface of the arrowhead through an animal’s soft flesh to increase the likelihood of a successful kill and minimize undue suffering of the animal. Ex. 1001, 1:26–30, 4:8–10, 4:21–24. The purpose of Lint’s barbs, on the other hand, is to resist removal of the arrow from an animal. Ex. 1002, 2:67–70. Indeed, Lint discloses that only when the arrowhead has “completely penetrated the flesh of an animal” does the spring urge the barbs into the extended position. Id. Thus, contrary to the conclusory assertions of Petitioner and Petitioner’s witness, Dr. Kuhn (see Pet. 49–51; Ex. 1019 ¶ 119), the recited blade members and Lint’s barbs perform vastly different functions.
