      “their plain and ordinary meaning, with one exception. Pet. 3. Specifically, Petitioner asserts “storage element” or “energy storage element” are recited “interchangeably” in the claims and should each be construed to mean “an element of a system that stores non-negligible amounts of energy from an input EM signal,” which Petitioner notes was “determined by the Board and affirmed by the [U.S. Court of Appeals for the] Federal Circuit.” Id. (citing ParkerVision, Inc. v. Vidal, 88 F.4th 969, 976 (Fed. Cir. 2023) (holding “ParkerVision acted as its own lexicographer to define the term ‘storage element’” and “the Board’s construction of ‘storage element’ [(quoted above)] correctly tracks the lexicography provided by [ParkerVision]”) (citing U.S. Patent No. 6,061,551 (“the ’551 patent”), 66:55–67)). Petitioner contends that, like U.S. Patent No. 7,110,444 that was at issue in ParkerVision v. Vidal, the ’528 patent also incorporates the ’551 patent by reference. Pet. 4 (citing Ex. 1001, 1:30–34). And Petitioner notes that the ’528 patent “includes an identical disclosure to that deemed dispositive from the incorporated by reference ’551 patent.” Id. (citing Ex. 1001, 73:9–22 (which Petitioner contends defines “storage module”)). Further, Petitioner asserts “[n]o intrinsic evidence demands a different construction” because, even though claim 1 recites “system,” “energy,” and “transfer,” it does so “in isolation” and “does not recite ‘energy transfer system,’ let alone restrict the claimed ‘storage element’ to any energy transfer system.” Id. at 5 (also contending the file history of the ’528 patent does not support a different construction). Petitioner also contends “the proposed combinations teach the claimed ‘storage element’ or ‘energy storage element,’ even including the alleged condition of ‘low impedance load’ that purportedly ‘goes to the heart of what makes an element, a “storage” element.’” Id. Patent Owner does not take a position on claim construction in the Preliminary Response. See generally Prelim. Resp. On the present record at this stage of the proceeding, we agree with Petitioner, for the reasons discussed above, that “storage element” and “energy storage element” are used interchangeably in the claims and should be construed consistently with our prior construction of “storage element,” which, as noted above, was affirmed by the Federal Circuit, to mean “an element of a system that stores non-negligible amounts of energy from an input EM signal.” We need not construe any other claim terms expressly because there is no present controversy as to the meaning of any other claim terms in this proceeding.

      “h. Summary as to Claim 14 For the reasons discussed above, on the present record we find that Petitioner has established that the combination of Tayloe and TI Datasheet teaches each of the elements of claim 14 and that one of ordinary skill in the art would have been motivated to combine the teachings of these two references as proposed by Petitioner with a reasonable expectation of success in so doing. 3. Objective Indicia of Nonobviousness In the record presently before us, neither Petitioner nor Patent Owner has presented any evidence of objective indicia of nonobviousness. 4. Weighing the Graham Factors “Once all relevant facts are found, the ultimate legal determination [of obviousness] involves the weighing of the fact findings to conclude whether the claimed combination would have been obvious to an ordinary artisan.” Arctic Cat, 876 F.3d at 1361. On balance, considering the record presently before us, Petitioner has established a reasonable likelihood that it would prevail in showing that the combination of Tayloe and TI Datasheet would have rendered the subject matter of claim 14 of the ’177 patent obvious to one of ordinary skill in the art at the time of the invention.” slip op. at 35

      “A datasheet is a well-known resource for learning detailed information of the multiplexer/demultiplexer, and a [person of ordinary skill in the art] would have been motivated to consult the TI Datasheet for a more complete understanding of Tayloe’s express teachings of the SN74CBT3253 demultiplexer, the only matching multiplexer available at the time.

When viewing the detailed diagram of the SN74CBT3253 demultiplexer, a [person of ordinary skill in the art] would have been motivated to apply four of the switches because the architecture of one switch on the demultiplexer is analogous to one of the four switching paths of Tayloe’s commutating switch 38.

Even though TI identifies four claim terms in total in the Petition, TI argues that the asserted prior art renders the challenged claims unpatentable under any reasonable construction of those claim terms. See, e.g., id. at 4 (arguing that the “prior art analyzed here renders the claims unpatentable under either [party’s] constructions” proposed in the district court case), 6 (arguing that the “prior art renders the Challenged Claims unpatentable under . . . the [Board’s] constructions”).

Compare Pet. 16–71, with Samsung Pet. 15–68; see Mot. Resp. 1. And as discussed above, copying a previously instituted petition is “common in the joinder context” and “an accepted approach.” Expedia, IPR2022-00785, Paper 16 at 7–9; see supra § III.C.1. Further, any differences between the Petition and Samsung’s petition did not result from roadmapping to correct a deficiency in Samsung’s petition because the Board instituted review in the Samsung IPR. See Code200, IPR2022-00861, Paper 18 at 5; Gen. Plastic, IPR2016-01357, Paper 19 at 17; Samsung Inst. Dec. 87. For these reasons, factor (3) does not favor discretionary denial.” slip op. at 35

An inter partes review may not be instituted unless it is determined that “the information presented in the petition filed under section 311 and any response filed under section 313 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). before us, that there is a reasonable likelihood Petitioner would prevail in showing at least one of the challenged claims is unpatentable. Furthermore, we deny Patent Owner’s request that we exercise our discretion to deny institution in this proceeding based on the filing by Petitioner of two additional parallel petitions or due to the alleged lack of particularity in the instant Petition.

For reasons discussed in our concurrent Decisions Denying Institution in IPR2024-00414 and IPR2024-00415, we agree with Patent Owner that plural petitions are not warranted.

In Adaptics, the petitioner’s use of “and/or” in its challenges yielded “hundreds of possible combinations.” Adaptics, Paper 20 at 19. In addition, the petitioner in Adaptics asserted a “catch-all” ground asserting obviousness as an alternative if its extensive anticipation grounds failed. Id. at 14. In finding that the petition lacked sufficient particularity, the Board cited this “catch-all” ground as “the worst offender.” Id. at 18.

      “Fintiv, we agree that it indicates that this factor weighs in favor of discretionary denial because the trial date is scheduled to occur before the final written decision deadline. However, the trial date here is closer to the deadline for the final written decision, with only a two-month difference here rather than the six-month difference in Fintiv, which increases the possibility here that any unforeseen delay in the district court proceeding could cause the order of those two events to reverse. Fintiv at 9 (“If the court’s trial date is at or around the same time as the projected statutory deadline . . . the decision whether to institute will likely implicate other factors.”).

      “access switches on the second port.” Ex. 1001, claim 5. We find that Petitioner has not provided sufficient information for us to find a reasonable likelihood that Gai teaches or suggests dependent claims 5 and 17 at this time. Dependent claim 17 is similar to claim 5, but depends on claim 16 (which in turn depends on independent claim 13), adding “wherein the protocol processor is adapted to update the entries in the database to point to the second access port before receiving the communication traffic from the one or more access switches on the second port.” Id. at claim 17. These claims both require the switch implementing the method for rapid recovery, such as switch 124 in Petitioner’s example discussed above, to update its filtering database before receiving communication traffic from access switches, such as access switches 115 and 116 in Petitioner’s example. Pet. 58. That effectively means that switch 124 must update its database immediately upon transitioning to the new port either before or at the same time it transmits dummy messages to the access switches. So this differs from the analysis for claim 4 because allowing the corresponding entry in the filtering database to time out will not be sufficient to ensure that the entries will be updated before receiving communication traffic from one of the access switches. There is no express disclosure from the portions of Gai cited by Petitioner of immediately updating the database on the switch implementing the method. Pet. 57–58, 94; Ex. 1005, 2:30–41, 5:36–39, 5:54–56, 12:62– 65. Based on the current record, we are also not persuaded by Petitioner’s declarant’s explanation of why Gai allegedly teaches or suggests this limitation. In the section addressing dependent claim 5, Dr. Houh asserts that: are transmitted before any communication traffic is received by the switch. As I discuss in Section VIII.A.5.ii, the filtering database is updated before transmitting the dummy messages. Accordingly, a POSITA would have understood that the database entries would have been updated before receiving any communication traffic from the access switches. Ex. 1003 ¶ 139. However, Section VIII.A.5.ii of Dr. Houh’s declaration relates to dependent claim 4 which does not have any timing requirement, and the citations to Gai there do not describe that the switch first updates its filtering database before sending the dummy message.12 Id. ¶¶ 133–136. Therefore, the conclusory and unsupported assertions that Gai teaches or suggests this limitation, or renders it obvious to a POSITA, do not persuade us that Petitioner has shown a reasonable likelihood of prevailing on these claims, at least at this stage of the proceeding.” slip op. at 58

      “Id. Therefore, after a failure and switchover, edge switch 124 transmits dummy traffic to access switch 116 over the second link. Id. Based on the current record, we agree that this example is at least suggested by Gai’s teaching that “the method and apparatus manifests, in part, as a series of novel commands that may be entered at the devices. The devices, moreover, may be classified as either access switches or backbone switches.” Ex. 1005, 6:6–9. Switch 124 is a backbone switch because it interconnects at least access switches 114–116, and, according to Gai, the invention can be implemented on that switch by entering the corresponding commands on it. Id. The rest of the example, whereby ports are switched based on a failure and dummy traffic that is transmitted to the access switches updates their filtering databases, also follows Gai’s teaching. Pet. 39–46; Ex. 1005, 5:35– 6:12. Patent Owner responds to this argument by asserting that “Gai itself never describes backbone switch 124 in such a way,” disputing it could transmit dummy traffic to access switch 116 over the second link. Prelim. Resp. 10–11. Rather, according to Patent Owner, “Gai clearly explains that such an action is in response to a port failure in access switch 114, not in teaching to the preferred embodiment that describes the failure occurring at switch 114, which we do not find warranted in view of the general teaching from Gai discussed above saying the invention can also be implemented on backbone switches.

      “on May 8, 2024 (see 35 U.S.C. § 314(b)(1)), and none of the relevant deadlines for fact discovery or expert discovery, or the date of the scheduled Markman hearing, will have passed by that date. As described by Petitioner, fact and expert discovery do not close until next year, the parties have not yet exchanged preliminary claim constructions, and the Markman hearing is not scheduled until December 4, 2024, approximately four months after our deadline for this decision. See Pet. 83. We also find that Petitioner’s diligence in filing the Petition only about a month after receiving Patent Owner’s infringement contentions, and only four months after the filing of the original complaint, supports this factor weighing more strongly against exercising our discretion to deny the Petition. See id. at 82. Accordingly, in view of the parties’ respective arguments, we find that factor 3 weighs strongly against discretionary denial. 4. Overlapping Issues with the Parallel Proceeding Under this factor, Petitioner stipulates that “[i]f the Board institutes trial, Petitioner will cease asserting in the co-pending litigation the combination of references on which trial is instituted for the claims, to the extent Petitioner even asserts the same combination in the district court.” Pet. 83. We find that this stipulation “mitigates to some degree the concerns of duplicative efforts between the district court and the Board, as well as concerns for potentially conflicting decisions.” Sand at 12. More specifically, if we institute, then by stipulation the court in the Cisco litigation will not have to determine whether the challenged claims of the ’279 patent would have been obvious in view of Kovvali, Kalman, Masters, and RFC 2892, and therefore the risk of inconsistent results is also reduced. against discretionary denial because the stipulation is limited in nature.10 Prelim. Resp. 20. We agree, and therefore find this factor weighs slightly against discretionary denial. Sand at 12 n.5 (“Petitioner stipulates only that it will not pursue, in district court, the ‘same grounds’ presented in the Petition in this case. . . . Petitioner could have stipulated that it would not pursue any grounds raised or that could have reasonable been raised in an IPR . . . .

      “Decision below, Petitioner relies on Kovvali alone as teaching all but two steps recited in independent claim 1, and Petitioner similarly relies on Kovvali alone as teaching all but two limitations of independent claim 15. See Pet. 26–50, 63–64. For those additional steps and limitations, Petitioner relies on combined teachings of Kovvali and Kalman. See id. at 42–47. As Petitioner points out and Patent Owner acknowledges, however, Kovvali was not previously presented to the Office during prosecution of the application for the ’279 patent. See id. at 80; Prelim. Resp. 26. Moreover, notwithstanding Patent Owner’s assertion that Drake has “similar[ities] to how Petitioner characterizes Kovvali,” Patent Owner identifies only that “Drake teaches a ‘management system for local area networks’ that features an ‘allocator,’ which determined ‘if requested facilities are available, and if so, reserves these facilities for the requesting station.’” Prelim. Resp. 26 (citing Ex. 2003, code (57)). In contrast, Petitioner’s reliance on Kovvali goes significantly beyond such high-level generalizations, providing a detailed mapping of Kovvali’s teachings to, for limitations [15.1]–[15.5] and [15.8] of independent claim 15, as well as to the additional limitations recited in each of dependent claims 2, 5, 11–14, and 18, with supporting testimony from Dr. Mir’s declaration. Pet. 27–42, 48–51, 55–56, 59–64, 67 (citing Ex. 1003 ¶¶ 62–103, 120–130, 146–150, 160–185). Notably, Patent Owner does not expressly contest Petitioner’s arguments with respect to those limitations at this stage of the proceeding. See generally Prelim. Resp. Nor does Patent Owner cite any evidence of arguments substantially the same as those presented by Petitioner having been presented during prosecution. Accordingly, on this record and after taking into account Becton, Dickinson factors (a), (b), and (d), cited by Advanced Bionics as relevant to the first part of the two-part framework set forth therein (see Advanced Bionics at 9–10), we are not persuaded that the same or substantially the same art previously was presented to the Office or that the same or substantially the same arguments previously were presented to the Office. Accordingly, we need not proceed to the second part of the framework, and we decline to exercise our discretion to deny institution under 35 U.S.C. § 325(d).” slip op. at 20
