See Ex. 1001, 1:11–62 (describing the invention in terms of wireless communications).

“We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

“(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

Moreover, the Board denied the Canon IPR largely due to the immediacy of an upcoming district court trial. Id. at 5–11. Thus, even if Patent Owner’s request did not fail under the first prong of Advanced Bionics, the request would fail under the second prong, which considers Becton, Dickson8 factors (c) and (f). Advanced Bionics, Paper 6 at 10. Factor (c) “focuses on the record developed by the Office in previously reviewing art or arguments” and informs “the petitioner’s showing under factor[] . . .

Principal among them is the first factor—“whether the same petitioner previously filed a petition directed to the same claims of the same patent.” Id. at 16. This factor has been extended to consider not only whether the petitioner is the same as a previous petitioner, but whether the petitioner has “a significant relationship” with the previous petitioner. See Valve Corp. v. Elec. Scripting Prods., Inc., IPR2019-00062, Paper 11 at 9– 10 (PTAB Apr. 2, 2019) (precedential). The Director has found that when two petitions challenge the same patent and “the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic (PTAB Apr. 19, 2024) (emphasis added). Petitioner and Sony are not the same party and the entities that constitute Petitioner contend that they “lack any legally significant relationship” with Sony. Pet. 86.

“As to the claim requirement that the direct memory access device concurrently write the packet buffer memory and the protocol stack layer memory, Petitioner asserts that neither Cornett nor Paatela explicitly describes the timing of packet writing. Pet. 42. Petitioner asserts, however, that Nelson discloses writing a packet header separately and in parallel with writing the entire packet. Id. (citing Ex. 1006, 6:66–7:4; Ex. 1003 ¶ 89). Indeed, Nelson explains that the parallel storage action “avoid[s] having to read the frames out of the [larger frame] buffer” when reading a header, which eliminates the need for a separate reading step and “allows the routing decision to be made before the [frame] buffer becomes available.” Ex. 1006, 2:1–22 (containing the quoted language), 7:1–4 (describing “parallel . . . storage”). Petitioner asserts that it would have been obvious to write the packet header at the same time as writing the entire packet in Cornett, because Cornett, Paatela, and Nelson are concerned with speed, and writing in parallel would increase speed (vs. writing serially). Id. at 43–44 (citing Ex. 1003 ¶ 90); see also id. at 26 (similar argument). Reviewing Petitioner’s position with respect to independent claim 13, we determine that Petitioner has addressed each limitation in sufficient detail and with adequate citations to the record. Petitioner has also provided sufficient reasons for combining the teachings of Cornett, Paatela, and Nelson with a reasonable expectation of success. Reviewing the record before us, we determine that Petitioner has established a reasonable likelihood of success in showing that claim 13 would have been obvious in view of Cornett, Paatela, and Nelson.” slip op. at 11
