    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “at the time the application was filed, we consider the level of ordinary skill in the pertinent art at the critical time. Graham, 383 U.S. at 17. The resolution of this question is important because it allows us to “maintain[] objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu–Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quotation omitted). Generally, it is easier to establish obviousness under a higher level of ordinary skill in the art. Innovention Toys, LLC v. MGA Entm’t, Inc., 637 F.3d 1314, 1323 (Fed. Cir. 2011) (“A less sophisticated level of skill generally favors a determination of nonobviousness . . . while a higher level of skill favors the reverse.”).” slip op. at 9

      “after November 13, 2018, a patent claim shall be construed using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. § 282(b). 37 C.F.R. § 42.100(b) (as amended Oct. 11, 2018). This rule adopts the same claim construction standard used by Article III federal courts, which follow Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc), and its progeny. Under this standard, the words of a claim are generally given their “ordinary and customary meaning,” which is the meaning the term would have to a person of ordinary skill at the time of the invention, in the context of the entire patent including the specification. See Phillips, 415 F.3d at 1312–13.” slip op. at 10

      “Pet. 15–18. Petitioner’s proposed constructions are consistent with the claim construction decision from related litigation or the parties’ prior stipulations regarding claim construction. Id.; Ex. 1023 (parties’ stipulation); Ex. 1027 (parties’ stipulation); Ex. 1028, pp. 24–32 (District Court order). Patent Owner does not dispute Petitioner’s proposed claim construction. PO Resp. passim. We note that, the District Court held, in a non-final order, that claims 1 and 12 were indefinite because of the term “in proximity.” Ex. 1028, 24– 28. The District Court, however, did not issue a final ruling with respect to claims 1 and 12 because the parties narrowed the dispute concerning the ’784 Patent to only claim 11. Ex. 2018, ¶ 3. We also note that we do not need to assess whether or not the term “in proximity” renders claims 1 and 12 indefinite to assess the Petition. Rather, we agree with Petitioner that the “in proximity” language is at least broad enough to “encompass” the matter set forth in Petitioner’s claim construction. See Pet. 17, 37–41. This is sufficient definition to make it logically possible to reach the merits of Petitioner’s challenge. See Intel Corp. v. Qualcomm Inc., 21 F.4th 801, 813 (Fed. Cir. 2021) (holding that indefiniteness only precludes a patentability determination 102 or 103 if the indefiniteness makes it “logically impossible” to reach such a decision).” slip op. at 11

Pet. 26 (citing Ex. 1008 ¶¶ 111–112). Patent Owner does not dispute Petitioner’s contentions regarding this recitation. Based on the entire trial record, we agree with Petitioner’s analysis and credit Mr. William’s testimony supporting Petitioner’s position. Thus, in view of the evidence of record, we find that Crane and Spain disclose the preamble of recitation 1.1.” slip op. at 20

      “b) Reason to Combine & Expectation of Success As explained earlier, Petitioner asserts that it would have been obvious to improve Zhou’s video stabilization techniques by using the techniques in Cai for using future frames to characterize the video as having zero motion or not. Pet. 36. Patent Owner first argues that neither reference “offers any hint or suggestion of combining such reactive systems to create a proactive stabilization solution.” Prelim. Resp. 17; see also id. at 17–19 (similar). Patent Owner has not offered a claim construction, or otherwise explained, how the claims require a “proactive stabilization solution.” Thus, this argument is unpersuasive. Patent Owner next argues that Zhou and Cai are technically incompatible. Id. at 20–23. In particular, Patent Owner argues that Zhou “uses buffering to adjust stabilization strength,” whereas Cai uses buffering “for trajectory adjustment and distinguishing jitter from zero-motion or lowspeed movements.” Id. at 21–22 (emphasis removed). On this record, however, we are not provided with sufficient technical reasoning explaining how using the buffer for one purpose precludes its use for another purpose. Patent Owner cites its declarant, Dr. Foroosh, but his testimony merely repeats Patent Owner’s arguments without any meaningful elucidation. Id. at 22 (citing Ex. 2001 ¶ 70); 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Xerox Corp. v. Bytemark, Inc., IPR2022- 00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). On this record, we are shown no technical impediment with using the buffer in Zhou for distinguishing non-zero motion by looking ahead some number of frames, as proposed in the Petition.” slip op. at 12

      “5. Conclusion for the Bell & Shi Ground In summary, we determine on this limited record that Petitioner has shown sufficiently that Shi discloses the low-light high-pass parameter of claim 1 and that there would have been a reason to combine Bell and Shi. We adopt Petitioner’s remaining unchallenged assertions regarding claim 1 as our own. We are not persuaded by Patent Owner’s objective indicia analysis, which is lacking a showing of nexus. In conclusion, we determine that Petitioner has demonstrated a reasonable likelihood of success in showing that the subject matter of claim 1 of the ’840 patent would have been obvious in view of Bell and Shi. No issue unique to any of the other claims in this ground is raised at this time.” slip op. at 17

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownOther

      “Looking to the claim language itself, we note that the claim mentions “low-light high-pass parameter” once, in the context of listing it as one of three alternative things covered by the claim. Ex. 1001, 30:35–38. We find the specification of the ’840 patent discusses the low-light high-pass parameter in two paragraphs. Id. at 21:59–22:21. In these passages, the ’840 patent states that the low-light high-pass parameter may be “a parameter that controls the amount/strength of smoothing performed to generate the smoothed trajectory.” Id. at 21:59–61. The parameter may take a value corresponding to the amount of motion blur compensation to be used. Id. at 22:8–21. Thus, the specification states that the low-light high-pass parameter is used to control the amount of motion blur compensation.” slip op. at 8

      “Patent Owner then argues that Bell and Shi are incompatible techniques and would not be combined. Prelim. Resp. 19–20. In particular, Patent Owner argues that Bell preemptively adjusts for future motion, whereas Shi reacts only after blur is detected. Id. at 20. On this record, this argument is unpersuasive because Patent Owner has not sufficiently explained the alleged technical incompatibility. Patent Owner’s position relies on the testimony of Dr. Foroosh, but we do not credit his testimony here because it merely mirrors what Patent Owner has argued, without technical explanation. Ex. 2001 ¶ 65; 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight”); Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In contrast, both Bell and Shi look at future frames for motion smoothing. Ex. 1006, 10:10–16 (describing Bell’s “look-ahead buffer”); Ex. 1007, 1:61– 65 (describing Shi’s “use [of] future frames”). Thus, on this record, we are not persuaded that there is a technical incompatibility in the manner Patent Owner alleges.” slip op. at 14

    • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusOther

      “Prelim. Resp. 23–31. Patent Owner’s position is underpinned by its evidence purporting to show its “dominant position in the U.S. action camera market,” based on its “HyperSmooth technology” that it asserts “has garnered widespread industry recognition.” See generally id. However, even if we were to accept Patent Owner’s argument that it has a revolutionary and successful product, that does not mean that all claims of its patents would have been non-obvious. For us to give substantial weight to objective indicia of non-obviousness, a proponent must establish a nexus between the evidence and the merits of the claimed invention. ClassCo, Inc., v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” Id. (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)); see also Wyers v. Master Lock Co., 616 F.3d 1231, 1246 (Fed. Cir. 2010) (“For objective evidence of secondary considerations to be accorded substantial weight, its proponent must establish a nexus between the evidence and the merits of the claimed invention.”) (cleaned up). Patent Owner here has not attempted a nexus analysis in its Preliminary Response. At best, it improperly incorporates by reference a claim chart (Exhibit 2016) served in the related ITC proceeding. Prelim. Resp. 25; 37 C.F.R. § 42.6(a)(3) (“Arguments must not be incorporated by reference from one document into another document.”). Even then, the claim chart appears to admit that claim 1 does not read on Patent Owner’s technology. Ex. 2016, 30.2 On this record, we cannot determine whether, or the extent to which, Patent Owner’s assertions of non-obviousness are due to the claimed invention because of the failure to show nexus to the subject matter of the claims.” slip op. at 16

Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91.

Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13.

First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery.

Ex. 1014, 2:14–30 (explaining the long training sequence for a conventional 802.11a preamble), 6:11–15. Notably, Jones also teaches that “packet formation block 314 may insert appropriate complex values at unused . . . subcarrier locations in each group of symbols D[k],” and that “any or all of the subcarriers k may be used to transmit data, thereby increasing the data rate.” Id. at 6:15–20 (emphasis added); see also id. at 8:22–24 (teaching that an extended long training sequence “can contain more than 52 non-zero subcarriers”). At this stage, we credit Dr. Buehrer’s testimony that one of ordinary skill in the art would have been motivated to “add[] four subcarriers to 802.11a data and training fields [to] increase[] data rate throughput as taught in . . . Jones,” as this testimony is consistent with Jones’s teachings. Ex. 1005 ¶ 107. In addition, we agree with Petitioner and find that one of ordinary skill in the art extending the long training sequence would want to use the same 52 center subcarriers to maintain backwards compatibility with 802.11a. Pet. 28–29. This is supported by Jones’s teaching of having a long training sequence that “is usable in a process for determining whether the packet is an 802.11a packet or an extended-mode packet.” Ex. 1014, 8:37– 40. Moreover, Jones’s L2 example of an extended long training sequence maintains the same 52 center subcarriers as 802.11a, which also supports this finding. Id. at Fig. 4; Ex. 1005 ¶¶ 96, 113. Thus, up to 11 subcarriers unused in 802.11a could be used for an extended long training sequence. “more than 52 non-zero subcarriers” can be used for an extended long training sequence, which explicitly teaches that only a portion of the 11 subcarriers may be used. Ex. 1014, 6:15–20, 8:22–24. In light of the above teachings, we find that one of ordinary skill in the art would have found it obvious to use only the next 4 nearest to the center of these 11 unused subcarriers. Ex. 1005 ¶ 87. The remaining 7 subcarriers would remain at zero.” slip op. at 15
