    “As set forth in the Director’s Memorandum, Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (dated June 21, 2022), at 7, available at https://www.uspto.gov/sites/default/files/documents/interim_proc_discretion ary_denials_aia_parallel_district_court_litigation_memo_20220621_.pdf, the PTAB will not discretionarily deny institution of an IPR . . . in view of parallel district court litigation where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.

    “We disagree. The Petition is clear that it presents alternative challenges where Goldberg, Thacker, ITU-T J.83, and/or AAPA are added to the combination of Gibson and Schiltz or are added to Crols, if the term “cable modem,” recited in the preamble of claim 1, is determined to be limiting. Pet. 6–7. In the context presented here, “and/or” clearly means one or more of the four additional references. And Petitioner’s reliance on one or more of the additional references is clear in the context of the issues before us based on Petitioner’s analysis of the preamble of claim 1, where Petitioner clearly states, “[a]nd to the extent that the preamble is limiting and requires a ‘cable modem,’ it would have been obvious to use the modem of Gibson (as modified by Schiltz, discussed below) as a cable modem, in view of Thacker, Goldberg, ITU-T J.83, and/or AAPA.” Pet. 42 (Ground 1); see id. at 66–67 (similarly asserting, in the context of Ground 2, that, “[t]o the extent that the preamble is limiting and requires a ‘cable modem,’ it would have been obvious to use the modem of Crols as a cable modem, in view of Thacker, Goldberg, ITU-T J.83, and/or AAPA”). Petitioner also includes a discussion as to why one of ordinary skill in the art would have been motivated to “use the modems of Gibson modified with Schiltz (Ground 1), and Crols (Ground 2), as ‘cable modems,’ in view of the DOCSIS References (Thacker and Goldberg), ITU-T J.83, and AAPA,” and would have had a reasonable expectation of success in so doing.

The Combination of Wolfe and Pfeffer To demonstrate obviousness, Petitioner must provide “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418. More specifically, to prevail, Petitioner must demonstrate by a preponderance of evidence that “a skilled artisan would have had reason to combine the teaching of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success from doing so.” PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1193 (Fed. Cir. 2014).

Petitioner also contends that the combination would provide additional benefits to Wolfe’s system from Pfeffer’s additional features, such as providing “continuous updates to the incident scenario model saved for future use, recommendations for the most effective methods to respond to the incident based on past responses and current trends, and determining if an incident should be elevated based on the number of people involved in the incident.” Pet. 26 (citing Ex. 1003 ¶ 77; Ex. 1005 ¶¶ 28, 77, 85).

VirnetX Inc. v Apple, Inc., 909 F.3d 1375, 1377 (Fed. Cir. 2018) (citing Stephen Slesinger, Inc. v. Disney Enterprises, Inc., 702 F.3d 640, 644 (Fed. Cir. 2012)). To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet. Reply 24; Ex. 1017, 31–34 (final written decision determining obviousness of claims 9, 10, 14, and 16 of the ’473 patent over Wu and Sabat-426); Ex. 1072, 5 (summarizing the final written decision regarding the packetizing limitations), 10–16 (finding no error in the determinations regarding the packetizing limitations).” slip op. at 12

    “would have a bachelor’s degree in electrical engineering (or equivalent field) with 2–3 years of work experience in wireless communications.” Pet. 21 (citing Ex. 1003 ¶¶ 20–22). Patent Owner argues that one of ordinary skill in the art “would have an educational background in electrical engineering and experience in the design of wireless communication systems,” and “[m]ore particularly, a POSA would be a person with a bachelor’s degree in electrical engineering (or a similar technical degree or equivalent work experience) and at least 3 years of experience working with wireless communication systems.” PO Resp. 13. We found in the Decision on Institution that Patent Owner’s definition was generally consistent with Petitioner’s definition, with the exception of requiring 3 years or more (as opposed to 2 to 3 years) of work experience in wireless communication systems and, for the purpose of institution, we adopted Petitioner’s provided definition for the level of skill of a person of ordinary skill in the art as reasonable and consistent with the prior art. Dec. on Inst. 20–21.

    “institution of inter partes review of claims 1–19 (“the challenged claims”) of U.S. Patent No. 10,334,499 B2 (Ex. 1001, “the ’499 patent”). Dali Wireless Inc. (“Patent Owner”) filed a Preliminary Response (Paper 7, “Prelim. Resp.”). Ericsson filed a Preliminary Reply (Paper 9). We determined that the information presented in the Petition established that there was a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims, and therefore we instituted this proceeding on March 9, 2023, as to all challenged claims and all grounds of unpatentability. Paper 11 (“Dec. on Inst.”). We granted a request in IPR2023-00831 by AT&T Corp., AT&T Communications LLC, AT&T Services, Inc., AT&T Mobility LLC, and AT&T Mobility II LLC to be joined as a Petitioner in this proceeding. Paper 19. After a joint request of Patent Owner and Ericsson, we terminated the proceeding as to Ericsson, leaving AT&T Corp., AT&T Communications LLC, AT&T Services, Inc., AT&T Mobility LLC, and AT&T Mobility II LLC (“Petitioner”) as the lead (and sole) petitioner in this proceeding.

To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1004. Thus issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence.

    “a . . . set of radio resources” is not limited to and does not necessarily include configuration information that is required to or used to reconfigure remote radio units. As Petitioner argues, there does not appear to be any indication in the specification and other intrinsic evidence that “digital representation” should be given more than its ordinary meaning, or that an underlying construction of “radio resources” would not be applied to this claim term, which explicitly includes “radio resources.” Pet. Reply 9–10 (citing Ex. 1001, representation” in the specification of the ’499 patent). Our construction is further supported by the language of the claims, which requires that each “set of radio resources” is “for transmission at an antenna of the first remote unit.” Ex. 1001, 14:17–19, 14:22–24, 15:3–5, 15:8–10, 16:6–8, 16:11–13. With respect to the “digital representation” of “set[s] of radio resources,” the specification of the ’499 patent describes that in the downlink (base station to DRU antenna) path for data, RF signals received at the DAU from base station(s), are down-converted, digitized, and further processed resulting in “independently serialized, parallel data streams” that are delivered to DRUs. Ex. 1001, 4:63–5:12. Petitioner contends that this description of delivery of a digitized version of an RF signal to DRUs describes the sending/transmission of a digital representation of the radio. Pet. 9–10. While Patent Owner appears to argue that a “digital representation” of a radio resource would be only an “identifier” of, e.g., an RF carrier (PO Resp. 18), this does not appear to be supported by the specification or the cited testimony of Dr. Chrissan. We do not see a reason to relate “digital representation of . . . a set of radio resources” in the claims to the description in the ’499 patent specification of the remote configuration of DRU parameter settings via the DAU, including detecting or determining radio resources assigned to a DRU and configuring the DRU, turning on and off individual carriers transmitted and received by a DRU. PO Resp. 16–18 (citing Ex. 1001, 4:50–62, 6:31–44, 7:44–50, 12:15–39, 12:58–13:2). No cited portion of the specification describes these signals sent from a DAU to control a DRU as digital representations of a set of radio resources. While Patent Owner cites, in support, Dr. Chrissan’s declaration, Dr. Chrissan does” slip op. at 16
