    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “In our Institution Decision, we adopted Petitioner’s proposed level of ordinary skill in the art, with the exclusion of “at least” because it introduces ambiguity. Inst. Dec. 8. Patent Owner “does not dispute the Board’s findings on the qualifications of a POSA [person of ordinary skill in the art] for purposes of this proceeding.” See RMTA 13. We determine that Petitioner’s definition, with the exclusion of “at least,” is consistent with the prior art of record and the skill reflected in the Specification of the ’034 patent and we use this level of skill here in the evaluation of the Revised Motion to Amend.” slip op. at 9

      “Patent Owner argues that “claim construction is not necessary” and that “the meaning of the claims would be easily understood by a POSA.” RMTA 13. In the Petition, Petitioner proposed constructions for the terms “client device” and “first server,” and the original claims were rendered obvious under this construction. Pet. 23–27. Petitioner does not assert that the substitute claims of the Revised Motion to Amend are anticipated or rendered obvious by prior art or are patent ineligible. See generally RMTA Opp. Nor does Petitioner’s patentability challenge of the substitute claims contend that express construction is needed. See generally id. For purposes of this Decision, we determine that express claim construction is unnecessary. We need only construe terms that are necessary to resolve disputes. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

Patent Owner argues that we should construe “packetize” to mean “create data packets that include destination information.” PO Resp. 19–20. Patent Owner argues that this is consistent with how the Board previously interpreted this claim term in the 00571 IPR. PO Resp. 19 (citing Ex. 1017). We do not need to construe “packetizing” because collateral estoppel prevents Patent Owner from arguing that Wu does not disclose “packetizing” as explained below.

      “When deciding whether issue preclusion applies, we consider whether: (1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party. 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

Patent Owner argues that one of ordinary skill would not have been motivated to combine Littleworth and Linder as Petitioner proposes because Linder is limited to corresponding stereoscopic images and would not have been suitable for correlating Littleworth’s non-stereoscopic imagery.

As we explained there, the evidence of record, including Dr. Forsyth’s testimony and relevant passages from Linder, supports that Linder’s correlation method applies more broadly than to just stereoscopic images, and none of the additional material Patent Owner cites undermines Petitioner’s proposed combination. See IPR2022-01009, Paper 28 at 52–54, 56–67.

Petitioner identifies R1, R2, R3 and switches ka and kb as the claimed variable impedance. See, e.g., Pet. 39–41. The Petition (and the supporting Baker Declaration) do not explain adequately how, under this interpretation by Petitioner and its expert, Rauhala meets the adjusting an impedance “in the signal path” limitation. See Prelim. Resp. 39–41. For the reasons given, therefore, even if we were to disagree with Patent Owner’s construction of “impedance,” we agree with Patent Owner that Petitioner fails to demonstrate sufficiently that Rauhala meets the limitation in claims 7 and 19 requiring “dynamically adjusting one or more of an impedance . . . in the [receiver] signal path.” For the reasons given, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claims 11 and 13 as anticipated by Rauhala.

      “We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process.

On balance, Petitioner’s proposal of education plus a minimum of two years of experience is a better reflection of the level of skill in the prior art. For example, Rauhala presents functional block diagrams of signal strength information. See, e.g., Ex. 1004, Figs. 1–5, ¶¶ 15, 17, 19, 21.

      “strength indicator circuits 440 and 450, the written description unambiguously discloses that each circuit determines the cumulative signal level of the desired signal and the interfering signals. Neither circuit determines only the signal strength of the interferer signals, nor does a circuit determine only the signal strength of the desired signal. In other words, the written description does not support a limited reading of the claim language so as to require two separate circuits—one circuit for determining a a signal strength of the desired signal. Thus, based on this preliminary record, we do not construe the circuit limitation as requiring the wireless transceiver necessarily to have two circuits, one circuit for determining a signal strength of the interferer signal and a different circuit for determining a signal strength of the desired signal, because, under that reading of the claim, the only embodiment in the written description would not fall within the scope of the claim. It is well-established that “[s]uch an interpretation is rarely, if ever, correct and would require highly persuasive evidentiary support,” which is not present in this record as discussed below.

      “As explained above, however, on this preliminary record, we do not interpret the circuit limitation to impose a timing requirement such that the determining has to occur at precisely the same time. Nor at this preliminary juncture do we read a precise timing requirement into the circuit limitation based on written description disclosure that the desired signal and the interferer signal are part of the received signal input spectrum. As explained above, for example, the written description describes a circuit providing a cumulative signal level corresponding to the sum of the desired and interfering signals. Ex. 1001, 6:59–67. As such, the written description describes making the determinations on two signals that are part of the received signal input spectrum. Patent Owner argues that Rauhala does not disclose “two determinations of two different signal strengths together.” Prelim. Resp. 40. We do not agree with Patent Owner on this preliminary record. Rauhala’s disclosure of providing control bits based on the comparisons of the signal strengths to respective thresholds, discussed above, also undermines Patent Owner’s argument that detector DET, which (i) provides one or the other and (ii) needs to be re-tuned to read the other signal, cannot anticipate the claim. Notably, for example, Rauhala discloses setting control bits based on comparisons of the respective signal strengths to thresholds: cM. Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the same time smaller than Sn. Otherwise, signal cA is 1. Signal cA is taken to amplifiers Al and A2. Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Ex. 1004 ¶ 17 (emphases added). Here Rauhala describes providing control signals based on the strength of both signals from the receive and neighboring channels, which undermines Patent Owner’s arguments.” slip op. at 25

      “On the present record and for the purpose of this Decision, we agree with Petitioner that the proper construction of “communications unit” encompasses multiple DRUs or antenna units. Although Patent Owner is correct that not every embodiment needs to be reflected in every claim, and indeed, some embodiments may not appear in any claim, we do not agree that there is evidence supporting Patent Owner’s argument that the construction of “communications unit” should be narrowed to the embodiment requiring only one DRU/antenna. The cited claims do not indicate that multiple units may not transmit at the sets of frequencies recited. Additionally, although Patent Owner cites claim 16 as requiring that each communications unit is a single DRU, if that were a correct reading of claim 16, it is not clear what the claim recitation would add, as it would not narrow the prior recitation of a “communications unit” from claim 15. Such interpretations are disfavored. See Cat Tech LLC v. TubeMaster, Inc., 528 F.3d 871, 885 (Fed.

      “This distinction is particularly significant because Harris describes that its low-power feature is realized by using “the test mode.” Ex. 1003, 4:64–65. The test mode uses a software-selected switch that allows the CPU to write to a register to control which power supply is provided to the memory. Id. at 3:9–18, 3:50–51. Thus, Harris describes that the low-power feature uses a software-defined switching threshold, and nothing about that threshold requires that it be the same as the threshold used for the failure mode. The failure mode, in contrast, is “a hardware controlled function” that monitors the voltage on the VDD terminal, and when that voltage “drops below a set level or threshold, the voltage on the Vstby terminal 132 is switched to power the memory 105 to sustain memory contents when either main or VDD power is failing.” Id. at 3:52–60. Accordingly, we do not agree with Patent Owner that “Harris’s system cannot use a threshold [for its low-power feature] lower than the power-failure detection threshold.” PO Resp. 11–12 (emphasis omitted). The two aspects use different mechanisms to control which power supply is provided to the memory. Relatedly, Patent Owner asserts that Petitioner fails to justify “why a POSITA would have been motivated to abandon the ‘failure mode’ in favor of pursuing the specific ‘low power feature.’” Id. at 14. Because Harris’s failure mode and low-power feature are distinct aspects of Harris’s operation, however, there would have been no need for skilled artisans to abandon one in favor of the other. In that regard, we credit Dr. Singh’s testimony that because Harris’s circuitry can be used for multiple functions, skilled artisans would have understood “how the operation of the circuitry would have been configured differently for those different functions or operations.” Ex. 1040 ¶ 9. Patent Owner argues additionally that, even if the low-power feature is distinct from the failure mode, Petitioner has not justified using the failure mode’s “set level or threshold” with a different threshold for the low-power feature. PO Resp. 13–14. But that argument ignores that the low-power feature uses software to control the switch, rather than the hardware-controlled failure mode, as described above. Because the low-power feature and failure mode are based on different controlling mechanisms, Harris already describes using different thresholds for switching the memory’s power supply in the two instances. And as Dr. Singh testifies, achieving the desired power savings or low-power operating parameters would have motivated skilled artisans to select a specific minimum operating voltage for the low-power feature.

      “When the evidence shows that a product includes “the invention disclosed and claimed in the patent,” we presume that any commercial success of the product is due to the patented invention. PPC Broadband v. Corning Optical Commc’ns, 815 F. 3d 734, 746–747 (Fed. Cir. 2016). Such a presumed nexus requires not only that a commercial product embodies the claims, but also that it is coextensive with them. See Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed.

According to Petitioner, Patent Owner fails to show the verdict demonstrates commercial success with a nexus to the challenged claims. Id. at 24. Petitioner argues that the challenged claims were not the basis for customer demand of the accused products. Id. (citing Ex. 1044, 811:13– 812:24 (Intel employee Adam King testifying that Intel’s customers care about numerous technical attributes, including graphics performance for video editing, camera quality for video conferencing and power efficiency for laptops)). Petitioner notes that Patent Owner accused only the “C6 SRAM multiplexer” feature of infringing the ’373 patent (Ex. 1042, 453:20– 25; Ex. 1044, 815:16–816:21) and that Patent Owner’s damages expert, Dr. Sullivan, “conceded that many of the thousands of other features ‘have nothing to do with what [Patent Owner] accuses.’” Pet. Reply 24 (quoting Ex. 1043, 690:19–691:24). The record before us does not show that Intel’s product or products underlying the infringement verdict are coextensive with “the invention disclosed and claimed.” See Fox Factory, 944 F.3d at 1373, 1377; Facebook, Inc. v. Express Mobile Inc., IPR2021-01457, Paper 38 at 76–80 (PTAB Mar. 14, 2023) (concluding an infringement verdict was insufficient to establish nexus). Rather, the record shows that the accused products contained many features beyond those claimed in the ’373 patent. Ex. 1043, 690:19–691:24; Ex. 1044, 815:16–816:21. That evidence persuades us that, regardless of a presumed nexus, the commercial success does not have a nexus with the challenged claims.” slip op. at 22

    • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

      “We agree with Petitioner. Both Harris and the ’373 patent are in the field of memory power supply. While Harris describes a voltage-supply system allowing for a particular testing approach, its field is not limited to its primary purpose of soft-defect testing on-chip memory. Rather, Harris also describes that its system allows other features such as failure protection and a low-power feature. Ex. 1003, 3:50–67, 5:59–5:4. Thus, we find that Harris’s field is memory power supply, and more specifically, switchable memory power supplies. As discussed, the ’373 patent describes its related art as making tradeoffs between performance and power when choosing voltage and frequency for processors and memory. Ex. 1001, 1:12–25. While the ’373 patent describes determining the minimum operating voltage for each part and storing that determined value (id. at 2:3–37, 6:22–8:15), its disclosures are considerably broader in scope. The patent describes selecting memory voltage based on multiple considerations, such as using the logic voltage when it is higher than the memory minimum operating voltage, or a variety of minimum voltages depending on operating circumstances. Id. at 3:30–5:41. As to the system controlling a memory’s power supply, the ’373 patent describes mechanisms that may be used to control a memory’s power supply, such as power supply selector 21. Id. at 2:52–59, 5:42–58. It details operation of the power supply controller 28 and selector 21. Id. at 8:33–9:4. The ’373 patent describes alternatively that memory may be permanently coupled to a particular voltage bus that is scaled to provide the desired power. Id. at 2:59–61, 5:61–67. The disclosures regarding mechanisms for controlling the memory power supply show that the ’373 patent’s field is broader than just determining the minimum operating voltage. We find that the ’373 patent’s field includes switchable memory power supplies, supporting that Harris is from the same field as the ’373 patent. As to whether Harris is reasonably pertinent to the problem addressed by the ’373 patent, Petitioner contends that the ’373 patent addresses “lowering power consumption in integrated circuits, considering that ‘different types of circuitry within a data processing system may have different ranges of allowable operating voltages’ and that ‘the processor may be able to operate at a lower voltage than is possible for the memory.’” Pet. Reply 19 (quoting Ex. 1001, 1:12–25, 2:5–7). Petitioner contends that Harris addresses the same problem with its circuit to “ensure the memory is provided with sufficient voltage to avoid data loss.” Pet. 14–15 (citing Ex. 1003, 3:54–56, 3:64–67 (Harris’s disclosure of switching memory power supply “to avoid memory data loss”)). Patent Owner’s expert agrees that the ’373 patent addresses “the problem of providing different voltages to different parts of the circuit” to accommodate different “allowable operating voltages.” PO Resp. 49 (quoting Ex. 2052 ¶ 159). As discussed above, Harris discloses a mechanism for providing different voltages to different parts of its circuit, whether for testing or low-power operation. Ex. 1003, 3:50–67, 5:59–5:4. We find that Harris is reasonably pertinent to the problem of providing different voltages to different parts of the circuit. While the ’373 patent addresses other problems also, that does not undermine the problem to which Harris is reasonably pertinent. See Ethicon LLC v. Intuitive Surgical, Inc., No. 2021-1601, 2022 WL 1576779, at *4 (Fed. Cir. May 19, 2022) (nonprecedential) (holding that the patent owner’s identification of an additional problem beyond that supporting analogous art was irrelevant); Donner Tech., LLC v. Pro Stage Gear, LLC, 979 F.3d 1353, 1361 (Fed. Cir. 2020) (noting the analysis considers “one or more problems to which the claimed invention relates”). Accordingly, Harris is analogous art to the ’373 patent because it is both from the same field of endeavor and reasonably pertinent to a problem confronting the inventor of the ’373 patent.” slip op. at 25
