The written description, however, indicates “[a] viral event is defined as occurring when one or more predefined parameter thresholds have been surpassed, as determined in the exemplary embodiment in the Network Monitor 302.” Ex. 1001, 4:40–43. As Petitioner notes, the written description also provides examples of predefined parameter thresholds used by Network Monitor 302 “to determine if the monitored network indicates that a viral event may be occurring or impending.” Ex. 1001, 5:9–12; Pet. 13–14 (citing Ex. 1001, 5:9–15). Examples of predefined parameter thresholds include an excessive number of wireless devices in an area, excessive use of wireless devices in an area, two highly dense clusters of wireless devices converging at a significant rate of speed, and the difference in the number of wireless devices in an area exceeds a threshold over consecutive time periods. Ex. 1001, 5:12–14, 5:27–31, 5:35 (“to assess the number . . . of wireless devices”), 5:48–51; see Pet. 14 (citing Ex. 1001, 5:26–31, 5:45–51).

“4. 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). Regarding the required articulate reasoning, Petitioner contends that “[a]lthough Wolfe teaches providing relevant crowd information to police, Wolfe does not provide the details for how to alert and notify the police.” Pet. 24 (citing Ex. 1004 ¶ 14). “Pfeffer, however, fills in Wolfe’s details by specifically teaching techniques for receiving information about crowds, evaluating the information, and alerting first responders when needed,” according to Petitioner. Pet. 24 (citing Ex. 1005, Abstract, ¶¶ 6, 40–41). 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). Regarding the required expectation of success, Petitioner contends that “[a] POSITA would have found the combination of Wolfe and Pfeffer predictable” because they are similar in that “both systems analyze crowd information to identify safety risks.” Pet. 25 (citing Ex. 1003 ¶ 75; Ex. 1004, Abstract, ¶¶ 11, 14; Ex. 1005 ¶ 28). Petitioner further asserts that “[a] POSITA would have had a reasonable expectation of success when combining Wolfe and Pfeffer because [they] are implemented in the same manner,” with both being implemented on servers and with Pfeffer indicating that its techniques could be “any combination of software and/or hardware that is configured to perform one or more tasks.” Pet. 25–26 (citing Ex. 1003 ¶ 78; Ex. 1004 ¶ 70, 74; Ex. 1005 ¶¶ 37, 32). Petitioner also contends “the combination would use known techniques (Pfeffer’s implementation details of an incident response method) to improve a similar system (Wolfe’s crowd detection and incident response system) in the same way (providing crowd details and incident information to first responders so that they may better respond to comprised crowd safety).” Pet. 26–27 (citing Ex. 1003 ¶¶ 77–79).

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)).

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.

“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.

“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. 8–9. The record does not contain further argument or evidence regarding the level of skill of one of ordinary skill in the art, and we again adopt Petitioner’s definition, which does not encompass an open-ended (“at least 3 years”) amount of experience and which is supported by the testimony of Dr. Houh. We would reach the same conclusions if we were to remove the open-ended terminology from Patent Owner’s definition and adopt that definition.” slip op. at 14

“We have authority to determine whether to institute an inter partes review. 37 C.F.R. § 42.4(a) (2023). Under 35 U.S.C. § 314(a), an inter partes review may not be instituted “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” A decision to institute under 35 U.S.C. § 314 may not institute on fewer than all claims challenged in the petition. 37 C.F.R. § 42.108(a) (implemented as a result of SAS Inst., Inc. v. Iancu, 138 S. Ct. 1348, 1359–60 (2018)). Upon consideration of the arguments and evidence presented by Petitioner and Patent Owner, we are persuaded that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing the unpatentability of at least one challenged claim. See 35 U.S.C. § 314(a). For the reasons explained below, we institute an inter partes review of all challenged claims.” slip op. at 2

“The purpose of requiring reasonable diligence by the first to conceive the invention but second to reduce to practice is to assure that the invention was not abandoned or unreasonably delayed by the first inventor during the period after the second inventor entered the field.” Brown v. Barbacid, 436 F.3d 1376, 1379 (Fed. Cir. 2006). “A patent owner need not prove the inventor continuously exercised reasonable diligence throughout the critical period; it must show there was reasonably continuous diligence.” Perfect Surgical Techniques, Inc. v. Olympus Am., Inc., 841 F.3d 1004, 1009 (Fed. Cir. 2016). “[T]here need not necessarily be evidence of activity on every single day if a satisfactory explanation is evidenced.” Monsanto Co. v. Mycogen Plant Sci., Inc., 261 F.3d 1356, 1369 (Fed. Cir. 2001). Thus, Patent Owner must provide an explanation that is satisfactory to indicate that the relied-upon computer modeling and prior art search update show reasonably continuous diligence from November 10, 2003 to January 15, 2004. Patent Owner has provided some evidence to show diligence from November 10, 2003 to January 15, 2004, but Patent Owner has not explained why, under the facts of this case, the evidence is sufficient to establish reasonably continuous diligence for the period before Bhandarkar’s effective filing date to the date of constructive reduction to practice. We have reviewed Petitioner’s contentions as to how Bhandarkar teaches the subject matter of the claims, and we find them sufficiently persuasive at this stage. Based upon the above-discussed evidence and that the optical combiner claimed in claims 1, 2, 6, 7, and 9 would have been obvious to one of ordinary skill in the art over Bhandarkar. slip op. at 26
- PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Decided for petitioner
“institution under 35 U.S.C. § 314(a) because the factors identified in Apple, Inc. v. Fintiv, Inc., IPR2020-00019, Paper 11 (PTAB Mar. 20, 2020) (precedential) (“Fintiv”), weigh in favor of denying institution in view of the district court litigation (Prelim. Resp. 68–69). A Memorandum from Director Vidal titled Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (USPTO June 21, 2022) (“Interim Procedure”)2 provides that “the PTAB will not deny institution of an IPR or PGR under Fintiv . . . 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” (Interim Procedure 9). Petitioner has submitted such a stipulation (Paper 11). Thus, we do not exercise discretion to deny institution under 35 U.S.C. § 314(a).” slip op. at 27

“B. Claim Construction In inter partes reviews, the Board construes claims using the same claim construction standard employed in a civil action under 35 U.S.C. § 282(b). 37 C.F.R. § 42.100(b) (2020). Under the principles set forth by our reviewing court, the “words of a claim ‘are generally given their ordinary and customary meaning,’” as would have been understood by a person of ordinary skill in the art in question at the time of the invention. Phillips v. AWH Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc) (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.
