We adopt this as the definition of one of ordinary skill in the art for the purposes of this Decision. We note that since it is unclear whether the bachelor’s degree in the proposed definition is considered by Petitioner to be “an advanced-level degree” we do not adopt years of experience for “an advanced-level degree” at this time.” slip op. at 8

      “blur[ring] . . . at least a portion of” an object, as recited in independent claims 2 and 225, and argues that displaying less detail in a portion of a background object because of the display of a semitransparent foreground object would have been “a type of blurring”. Pet. 32–33 (citing Ex. 1001, 99:51–53; Ex. 1004 ¶ 70; Ex. 1009, 3, 6; Ex. 1003 ¶ 93). Petitioner asserts that one of ordinary skill would have understood “blur” to mean “make or become unclear or less distinct” and that the ’754 patent, in a dependent claim, recites that a blur “includes changing a translucency” of an overlaying object. Id. (citing Ex. 1001, 99:51–53). Patent Owner does not address this contention. On the present record, Petitioner’s proposed construction appears correct and, for purposes of institution, we construe the blurring of an object as displaying that object with less detail. Otherwise, for institution and on the present record, we determine that none of the claim terms from the related litigation require construction, and neither do any other claim terms.

      “petition is warranted given the number of claims at issue. See Trial Practice Guide 59 (identifying situations where “two petitions . . . may be needed”). Patent Owner has asserted 166 claims in the co-pending district court litigation, and Petitioner challenges 91 unique claims in these petitions. See Ranking Notice 2; Ranking Response 2. Also, the vast majority of the challenged claims are asserted in litigation. See Ranking Response 2; Ex. 2004, 3. As a result, we agree that this is the type of “rare” situation where multiple parallel petitions are necessary. Petitioner’s primary argument is that seven petitions were required because the common sections needed to be repeated in each petition, which left few words for arguments directed to new claims (given word count limits). See Ranking Notice 2–3. But this argument is premised on an assumption that these common sections “require[d] approximately 8,350 words” (id. at 3), and Petitioner has not persuasively shown that so many words were actually required for these sections. Petitioner includes no explanation or justification of the length of the sections, but instead, it simply assumes that the words used were required. Having reviewed the analysis in those sections, we do not agree. In other words, although we agree that the common sections needed to be repeated in each petition (and that this reduced the number of words available for other analysis), we are not persuaded that the common sections required approximately 8,350 words. A petitioner is certainly entitled to allocate its words as it sees fit, and we typically have no reason to evaluate those strategic decisions; however, we agree with Patent Owner (see Ranking Response 3) that Petitioner cannot justify a large number of petitions by claiming that it needed additional words for its analysis (given the Board’s word count limits) unless Petitioner’s analysis was concise.” slip op. at 11

      “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.

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.

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.

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.

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.

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.

      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. 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. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. 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.

      “constructions. 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. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

      “52 subcarriers are used while “the DC subcarrier and 11 subcarriers near the edges of the 20 MHZ channel are not used for data transmission” (i.e., are set to zero). 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
