      “Petitioner argues that a person of ordinary skill in the art “would have had a bachelor’s degree, or equivalent, in electrical engineering, computer science, or a related field, and 2–3 years of experience researching, designing, or developing content delivery systems and related hardware, software, and firmware, or equivalent experience.” Pet. 4 (citing Ex. 1008 ¶¶ 36–40). Patent Owner does not dispute this. See PO Resp. 3 (citing Ex. 2001 ¶ 22). Because it is uncontested, supported by testimonial evidence, and appears consistent with the types of problems and solutions in the ’427 patent, we adopt the above articulation of the level of ordinary skill for this decision.” slip op. at 12

      “Having considered all the evidence of record relating to Mr. Taniguchi’s activities during the relevant time frame, we find that Patent Owner has not produced sufficient corroborating evidence to show that Mr. Taniguchi’s work on reducing to practice the claimed invention was reasonably continuous during the critical period between September 19, 2008 (the filing date of Ueda), and November 18, 2008 (the filing date of the Japanese patent application). Although there is corroborating evidence of diligence beginning on November 6, 2008, when Mr. Taniguchi transmitted a draft application to the Baba law firm, there is no evidence of any diligence prior to that date, other than Mr. Taniguchi’s own testimony. We do not agree with Patent Owner that the evidence of Mr. Taniguchi’s other activities for NEC, or research relating to IPTV, corroborate Mr. Taniguchi’s reduction to practice of the claimed invention. Although these activities may have something to do with the general subject matter of IPTV, Patent Owner has not shown any nexus between these activities and the challenged claims. See Naber, 567 F.2d at 385 (“It is well settled that, to satisfy the ‘reasonable diligence’ requirement . . . , the work relied on must ordinarily be directly related to reduction to practice of the invention . . . in issue.” (citing cases)). Although Mr. Taniguchi doubtlessly spent substantial time preparing the application he completed on November 6, 2008 (see Ex. 2017), there is no corroborating evidence that this work was reasonably continuous during the critical period. As far as the corroborating evidence attests, Mr. Taniguchi could have done no work on the draft until early November, or he could have worked on the draft briefly in August and put it aside until early November. Considering all the evidence as to Mr. Taniguchi’s activities, we find that Patent Owner has not met its burden of producing corroborating evidence that the named inventors of the ’427 patent exercised reasonably continuous diligence during the critical period when Ueda was filed until the constructive reduction to practice that occurred on November 18, 2008. Therefore, we determine, by a preponderance of the evidence, that Ueda is prior art to the challenged claims.” slip op. at 24

      “In general, we disagree with Patent Owner that, in showing a reason to incorporate the SIP Standard’s teachings about proxy servers, Petitioner must necessarily show that Ueda’s system was deficient or inferior.

Also, “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR, 550 U.S. at 416. For this reason and the specific reasons discussed below, we find Patent Owner’s arguments unpersuasive. The evidence of record suggests that it would have been within the ordinary skill in the art to modify Ueda’s system by replacing direct communication between content-providing device 150 and servers 191 or 192 with an indirect connection in the form of proxy servers using well-known, predictable techniques as described in the SIP Standard.” slip op. at 33

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayTeaching away not foundDecided for petitioner

      “(4) Whether Ueda Teaches Away from Providing Play-list Information While Establishing a Connection Finally, Patent Owner argues that Ueda teaches away from providing “play-list information” at the same time as establishing a connection, because Ueda teaches successfully completing user authentication before transmitting the playlist. PO Resp. 52–53 (citing Ex. 1003 ¶¶ 56, 365, Fig. 25; Ex. 2001 ¶ 99). According to Patent Owner, “Petitioner’s argument fails to reconcile[] this ordering of Ueda, which would prevent implementation of the proposed combination with the SDP Standard, in which the playlist is transmitted as part of the ‘Session Initiation.’” Id. at 53 (citing Ex. 2001 ¶ 100). In its Reply, Petitioner argues that limitation 1g “does not require transmitting ‘play-list information’ ‘at the same time’ as authentication, but at a same time ‘the one or more connection control servers executes a process for guaranteeing a communication bandwidth . . . as a process for establishing the connection.’” Pet. Reply 23. Petitioner also argues that the ’427 patent also describes an authentication step before transmitting the play-list information. Id. (citing Ex. 1001, 12:56–13:13, 13:50–58, Fig. 4). We find Petitioner’s arguments persuasive, and we disagree with Patent Owner that claim 1 restricts the timing of user authentication. As Petitioner notes, user authentication occurs in the ’427 patent before the process of establishing a connection as depicted in Figure 5. See Ex. 1001, 12:36–55, Fig. 4 (user authentication occurs when user equipment 2 is powered-up); id. at 13:50–58 (SIP message A501, at the beginning of Figure 5, includes “user authentication success information”). But we find nothing in the claim language, itself, that requires any particular timing for authentication. Nor do we understand Petitioner’s motivation-to-combine argument to hinge on the timing of authentication. Thus, Ueda does not “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004).” slip op. at 58

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightDecided for petitioner

      “We find Petitioner’s arguments persuasive. Petitioner does not rely solely on the SDP Standard for teaching the sending of play-list information, but also relies on Ueda, which discloses sending a playlist including an identification of main content, commercial content, and an output sequence, as we discuss in more detail below in the context of limitation 1h. See infra Section III.D.3(g). Petitioner relies on the SIP and SDP Standards for teaching that Ueda’s playlist, as with other data describing a session, may be formatted and transmitted as payload within a standard SIP message, for example using SDP fields. Based on the evidence of record, we find it persuasive that a person of ordinary skill in the art would have recognized SDP as a known way to format play-list information, since SDP has specific fields to convey the features of a playlist such as metadata and links to the content. See Pet. 50–52. Petitioner’s arguments are not based on improper hindsight bias. Although Petitioner argues that the SDP Standard “can” or “could” be used to format Ueda’s playlist, the evidence suggests that doing so would merely be “[t]he combination of familiar elements according to known methods,” and that kind of combination “is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416. The evidence shows that is the case here. As such, the Petition relies on the predictable combination of the prior art according to known methods and on various motivations to combine the references (see Supra Sections III.D.1–2), not on the ’427 patent itself, for teaching the combination.” slip op. at 57

      “Zhang, in light of Zill’s suggestion, to generate wakeup packets at Zhang’s server 404 rather than at end user 406. Pet. 36 (citing Ex. 1004 ¶¶ 61, 62; Ex. 1003 ¶¶ 112–119). Petitioner contends that doing so would have allowed Zhang to accommodate more types of requesting computers, including legacy hosts that might not have the software or hardware to securely process Zhang’s query replies and generate wakeup messages. Id. at 36–37 (citing Ex. 1004 ¶¶ 61, 62, 64, 65, 77; Ex. 1005 ¶ 111; Ex. 1003 ¶ 113).

Id. at 37 (citing Ex. 1004 ¶ 36; Ex. 1005 ¶¶ 40, 111; Ex. 1003 ¶¶ 114–115). Petitioner further argues that generating wakeup messages at the server would have reduced the quantity of messages exchanged containing sensitive information, reducing the risk of interception by a malicious actor. Id. at 37–38 (citing Ex. 1003 ¶ 116). Petitioner further argues that it would have been more efficient to generate the wakeup message at the server, as Zill suggests, as the server can include optimized hardware. Id. at 38 (citing Ex. 1003 ¶ 117). According to Petitioner, the combination would only require combining familiar elements according to known methods, to yield predictable results, and that a skilled artisan would have a reasonable expectation of success doing so. Id. at 38–39 (citing Ex. 1003 ¶¶ 118–119). Patent Owner does not yet contest these allegations.

      “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.

      “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

      “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.

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. 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.

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.

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.
