“Patent Owner attacks Petitioner’s “post-hoc rationalization for its proposed modification,” namely “more efficient processing or ‘simplifying processing and communications.’” Prelim. Resp. 26 (citing Pet. 18–19).14 Patent Owner asserts, in part, that Whitehead’s design already permits the “real time or near-real time” assembly of a custom media channel, so “it would be superfluous to include the same information again in the custom channel request.” Id. at 27–28 (citing, e.g., Ex. 1003, 4:40–44, 8:45–51, 11:45–49). At this stage, we tend to agree with Patent Owner. Petitioner acknowledges that “[m]ixing server 130 creates custom media channel 170 in real time or near real-time” yet asserts a POSITA would have modified Whitehead to speed up this process. See Pet. 18. If Whitehead already processes in real time or near real time, it is unclear why a skilled artisan would have sped up that process. Thus, Petitioner’s rationale does appear to be superfluous and hindsight-based at this stage.” slip op. at 17

“II. ANALYSIS A. Principles of Law Petitioner bears the burden of persuasion to prove unpatentability of the claims challenged in the Petition, and that burden never shifts to Patent Owner. Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) if present, any objective evidence of obviousness or non-obviousness.

“the gap between the playback deadline and the target schedule, (td(n) − tT(n)), is the target buffer duration, i.e., ‘the desired client buffer duration (in client time).’” Id. at 22–23 (quoting Chou ¶ 74). Petitioner also argues that “in efforts to match upper bound tb(n) to target schedule tT(n), Chou takes into consideration the time duration between target schedule tT(n) and the playback deadline td(n).” Thus, it appears Petitioner assembles three separate and distinct time intervals from Chou’s timing diagrams and equations to construct one contiguous time interval equivalent to claim 1’s remaining time. However, Chou does not recognize the time interval that Petitioner posits, and Petitioner has not persuasively shown that this combined time interval exists as a teaching in the prior art and is used as part of any step or decision involved in determining the code rate. As admitted by Petitioner’s expert, Dr. Reader, Petitioner’s analysis “used the claims as a road map to find limitations in the prior art.” Ex. 2015, 76:4–9 (Reader Deposition Transcript). See also Tr. 28:20–31:2 (Petitioner’s response to whether identification of and integration of separate time ranges described by Chou is hindsight reconstruction, Petitioner argues Chou’s device operates such that code rate is based on remaining time). Under the circumstances, this is improper because Petitioner and Dr. Reader do not justify this combination of separately identified time ranges except based solely on hindsight reconstruction of the claimed invention. However, even if that were not the case, we are not persuaded that Chou or the other asserted prior art references suggest using the combined time interval td(n) − ta(n) as the basis for any decision related to determining the code rate.” slip op. at 37

“d) Analysis In our Institution Decision, although expressing some uncertainty with respect to certain of Patent Owner’s arguments on the preliminary record then before us, “we [were] not persuaded by Petitioner’s contentions that [(1)] Wang teaches [1d]’s code rate” (Dec. 53 (citing Pet. 62–65) or (2) “a POSITA would have been motivated to combine the teachings of Chou and Wang” (id. at 54 (citing Pet. 74)).

Furthermore, Petitioner does not address or otherwise dispute Patent Owner’s arguments challenging the asserted obviousness of claims 1, 4–6, 10–16, and 19–26 over the combined teachings of Chou and Wang. Thus, for at least the reasons set forth in our Institution Decision, we agree with Patent Owner that Petitioner fails to show that (1) one skilled in the art would have combined the teachings of Chou and Wang or (2) the combined teaching of Chou and Wang renders limitation 1(d) obvious. e) Conclusion Regarding Claim 1 For the foregoing reasons, we determine that Petitioner has not shown by a preponderance of the evidence that independent claim 1 is unpatentable over the combination of Chou and Wang.” slip op. at 47

Determining the level of ordinary skill in the art involves various factors, 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) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). For purposes of this Institution Decision, we adopt the assessment offered by Petitioner, as it is not disputed by the Patent Owner and is consistent with the ’601 patent and the asserted prior art.10” slip op. at 9

“The Petition, to justify institution of review, must demonstrate a reasonable likelihood that Petitioner would prevail with respect to at least one challenged claim. 35 U.S.C. § 314(a) (2018). After considering the Petition, the Preliminary Response, and the evidence of record, we determine that the Petition has met this standard.

“7 Patent Owner criticizes the Shenoy Declaration as related to the internal firewall limitations and argues that this testimony should be given little weight: The testimony of Petitioner’s expert as to the “internal firewall” limitation should be given little weight as, apart from a single extended quotation in ¶91, it merely repeats verbatim the assertion in the Petition it purportedly supports. Compare Pet. at 38-41 with EX1003 at ¶¶90-96; see Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper No. 9 at 15 (PTAB Aug. 24, 2022) (precedential). Prelim. Resp. 5 n.1. We agree with Patent Owner.
