For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed.

Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). On the record before us, we do not agree that the ’171 Patent is entitled to a filing date earlier than Jan. 11, 2021. In particular, we do not agree that PCT ’199 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the performing preset padding before the FCS field of the trigger frame according to one embodiment (see Ex. 1012 ¶ 136, Fig. 20); and (4) inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a frame for allocating resource for uplink (UL) multi-user (MU) transmission to one or more terminals that includes the AID field set to a value related to a first padding field, when the padding field is included in the frame. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) an AID field for the MU UL resource allocation frame is set to a value, (2) that the AID field is set to a value related to the padding field, and (3) that the AID field is set to a value related to the padding field, and conditioned on the inclusion of the AID field in the frame. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20. PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment.” slip op. at 16

“To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art.

“C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v.

“Additionally, we credit the testimony of Dr. Almeroth, who opines that Kleve discloses that certain restrictions are sent with the request to generate a virtual key. Ex. 1003 ¶¶ 118–123. Specifically, Dr. Almeroth testifies that Kleve discloses that the virtual key “enable[s] the keyless drive system for the appropriate Temporary User during a given rental period.” Id. According to Dr. Almeroth, this “indicates that rental agreement restrictions were sent with the request so that the virtual key could be associated with said restrictions.” Id. (citing Ex. 1004 ¶¶ 39, 68 (“Once the rental period has expired the virtual key may be reset and cleared from the VCS.”)). Dr. Almeroth further testifies that the virtual key in Kleve is always generated after the rental agreement. Id. (citing Ex. 1004 ¶¶ 39 (“[O]nce the Temporary User selects the vehicle, pays the appropriate amount and signs a consent agreement, th[e]n the system may generate a virtual key to distribute to the Temporary User and VCS.”), 68). We do not agree with Patent Owner’s argument that Dr. Almeroth’s declaration testimony contradicts Kleve. See PO Resp. 27–29. Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing Ex. 2030, 27:5–10, 27:21–28:1). In a particular embodiment to which Dr. Almeroth was citing, he noted that the e-key is always generated after the rental agreement. See Ex. 2030, 26:14–20. Then the following exchange occurs: Q. So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don't know that the real world is necessarily cut and dry. So reading -- a person reading Kleve would understand it’s describing embodiments where it’s always the case. That might be a pretty common scenario, but I don't know that it would necessarily be a hard and fast rule in every embodiment or in the understanding a person of skill in the art would have. Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2001 ¶¶ 56–57. Therefore, we do not credit or agree with Dr. Malek’s testimony that Kleve teaches away from the concept of a virtual key created with the agreed-upon rental period as a restriction.

Obviousness is resolved based on underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness, i.e., secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17– 18 (1966). A party who petitions the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v. Teva Pharms. USA, Inc., 566 F.3d 989, 994 (Fed. Cir. 2009) (quoting Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1361 (Fed. Cir. 2007)). We assess Petitioner’s evidence and argument according to the above- referenced obviousness standard. We determine that the Petition satisfies the reasonable likelihood of prevailing standard under 35 U.S.C. § 314(a). We begin our analysis with a discussion of the Menon, Trefethen, RS6000, and POEref references. slip op. at 15

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed.

“Petitioner relies on the ordinary and customary meaning of the claim terms consistent with the Phillips standard. Pet. 12–13 (citing 37 C.F.R. § 42.100(b)). The Petition addresses the construction of “peer-to-peer architecture” recited in independent claims 1 and 30 of the ’034 patent, a limitation we need not construe to decide the institution question. Id. at 13; Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). Patent Owner contends that “no claim construction is required” to address the Petition’s asserted deficiencies. Prelim. Resp. 6. Patent Owner also contends, however, that the Petition relies on a “novel claim construction” of limitations [1.4.1] and [1.5.1]—“second [third] hardware processor with a plurality of processing cores”—to support Petitioner’s obviousness argument. Id. at 11–12.8 Patent Owner challenges the Petition’s reliance on “single core processors on different chips,” such as the Power3 single-core processors of the Symmetric Multi- Processor (“SMP”) configuration disclosed in the RS6000 reference, as a disclosure of limitations [1.4.1] and [1.5.1]. Id. Patent Owner contends that such single-core processors on different chips do not satisfy limitations [1.4.1] and [1.5.1] because the ’034 patent “claims only multicore processors.” Prelim. Resp. 5 (citing Ex. 1001, 7:15–27). Petitioner responds in part as follows: To the extent PO is implicitly arguing that RS6000’s “four, eight, twelve, or sixteen 375 MHz 630FP 64-bit processors” do not teach the recited “cores,” Patent Owner’s argument excludes embodiments described in the ’034 patent’s specification. The ’034 patent describes “[p]rocessor cores [as] generally independent microprocessors.” Ex.1001, 5:14–15. Patent Owner’s attempt to exclude RS6000 from the scope of the claims 8 Pursuant to the Board’s Order on Related Matter Updates (Paper 14), the parties filed the September 26, 2025 Claim Construction Order entered in the co-pending District Court litigation in this proceeding. Ex. 1085. The District Court Claim Construction Order did not construe the claim phrase “hardware processor with a plurality of processing cores.” Id. patent where the processor has independent microprocessors. Patent Owner’s attempt to distinguish RS6000’s Symmetric MultiProcessor as a “configuration” (Paper 8, 24) also fails because a “Symmetric MultiProcessor configuration” is no different than the ’034 patent’s description of a configuration of independent microprocessors. Id. Paper 9, 30.9 It is apparent there is a dispute over the plain meaning of Limitations [1.4.1] and [1.5.1], “a second [third] hardware processor with a plurality of processing cores,” recited in the independent claims.10 The parties are ordered to propose and support a particularized plain meaning or other construction of Limitations [1.4.1], [1.5.1], and [30.1.2] in their briefs. The parties are ordered to analyze the relevant claim language and cite to the specification and prosecution history in support of their claim construction, where applicable, with particular attention to the description of a hardware processor with a plurality of processing cores in the ’034 patent.

“Motivation to Combine and Analogous Art The Petition offers several motivations to combine Menon, Trefethen, RS6000, and POEref in the manner claimed in the ’034 patent with a reasonable expectation of success, which we find sufficient on the present record. The Petition first asserts that Menon and Trefethen are analogous prior art because they pertain to the same “field of cluster computing” as the ’034 patent and “are reasonably pertinent to the problem of the ’034 patent, namely, executing a single program on multiple nodes.” Pet. 22 (citing Ex.1001, 1:14–15; Ex.1003, ¶¶ 65–69; Ex. 1005, 2; Ex. 1006, Abstract). The Petition points out that Menon expressly cites and builds on the MultiMATLAB system taught by Trefethen. Id. (citing Ex. 1003 ¶ 71; Ex. 1005, 1–2). The Petition also contends that: Accordingly, Menon and Trefethen together represent a combination of prior art elements according to known methods (executing MATLAB code on a multiprocessor system) to yield the predictable result discussed in both papers: the MultiMATLAB system executing MATLAB in parallel to perform mathematical calculations. Id. at 22–23 (citing Ex. 1003 ¶ 70; Ex.1005, Abstract; Ex. 1006, 2–7).

“On this record, it is not entirely clear that comparing a BSS color value to determine if a receiving station is in that BSS is prohibited by the claim’s recitation “not to use” a BSS color, as Patent Owner’s argument implies. Rather, claim 1’s recitation “not to use a Basic Service Set (BSS) color when signaling information indicates that an operation based on the BSS color is not allowed” appears directed to prohibiting a particular operation based on the BSS color, not necessarily disregarding the BSS color entirely. Further, comparing BSS values to determine BSS identity appears consistent with claim 1’s recitation that “the BSS color is an communication terminal recognizes that a BSS color collision has occurred.” On this record, it appears that BSS color would need to be identified to determine if a color collision occurs. See Prelim. Resp. 4 (“BSS color collisions occur when two or more BSSs operating on the same frequency channel (and overlapping in coverage area) use the same BSS color. See ’163 Patent at 2:46-59, 10:41-62. In other words, a wireless communication terminal receives a signal with the same BSS color that device understands applies to it, even though the signal is intended for another device in a different BSS (albeit using the same BSS color). When a color collision is detected, the wireless communication terminal reports to the base wireless communication terminal, which will indicate that a color collision has occurred. ’163 Patent at 3:16-20.”). In that light, we see some merit in Petitioner’s position that an “operation based on BSS COLOR (e.g., allowing access and re-using the channel) is not allowed” based on the Low Power/High Interference Indicator, even if some reference is made to the BSS color to resolve a condition precedent to that determination, namely whether the data are from a different BSS. See Pet. 53–54 (citing Ex. 1009 ¶ 26; Ex. 1003 ¶ 170). Petitioner’s second theory is based on setting the color field to a reserved value of “0000,” which Petitioner argues “indicates that operations based on BSS COLOR are not allowed and the receiving STA does not use BSS COLOR.” Pet. 54–55 (citing Ex. 1009 ¶¶ 25, 29; Ex. 1003 ¶ 172). On this record, we question how setting a color value to 0000 can teach the subject matter of claim 1, which also requires that “the BSS color is an identifier of a BSS.” Petitioner acknowledges that a reserved value of 0000 in the color field does not identify a BSS. See Pet. 54–55 (asserting that a that a COLOR field value of ‘0000’ does not represent a valid BSS identifier”). We also recognize, however, that claim 7, depending from claim 1, recites “the BSS color indicated by the signaling field of the PPDU is a predetermined value” and that claim 8, depending from claim 7, recites that the predetermined value is 0. Thus, Choudhury’s reserved value disclosures appear to teach this subject matter of claims 7 and 8, even if claims 7 and 8 are inconsistent with claim 1’s requirement that “the BSS color is an identifier of a BSS.” See Ex. 1001, 21:23–30 (disclosing that the BSS color value may be set to a predetermined value such as zero).” slip op. at 12
