“field of the ’690 Patent would have had at least (1) an undergraduate degree in electrical engineering, computer engineering, computer science, or a comparable field of study and (2) at least two years of experience with optical data communications or a comparable field of work.” Pet. 14 (citing Ex. 1003 ¶ 22). Petitioner also states that “[i]ndividuals having different educational backgrounds and supplemental experience might still be of ordinary skill in the art if such experience compensates for any deficiencies in education relative to the criteria stated above” and “[i]n some cases, additional education might be an acceptable substitute for some experience, or vice versa.” Id. Patent Owner does not dispute Petitioner’s characterization of the level of skill in the art. See e.g., PO Resp. 9.

“Thus, although Petitioner contends that Njølstad implements a dynamically changeable frequency for each domain wherein a local “rate requirement can dynamically be configured” such that “the locally generated clock rate is just high enough to perform the actual processing task” at that rate (Pet. 31 (citing Ex. 1009 § IV.D)), such teaching merely supports Petitioner’s contention that the frequency is dynamically changeable at the local level (id.).

According to Patent Owner, while Soerensen claims priority to the Soerensen Provisional Application (Ex. 1022), the passages from Soerensen relied on in the Petition are not entitled to the benefit of the filing date of the Soerensen Provisional Application because the subject matter was not disclosed in the manner provided by 35 U.S.C. § 112.

Soto, IPR2023-00680, Paper 18 at 6 (Vidal Mar. 28, 2024) (“[P]rior art references are not ‘substantially the same’ when there are differences between them that are material to the Office’s prior consideration of the art.” (citing Wolfspeed, Inc. v. Trustees of Purdue University, IPR2022-00761, Paper 13 at 7–8 (Vidal Mar. 30, 2023)). Both parties agree that the Examiner distinguished Carmel during prosecution because it did not teach streamlets of the same duration. Pet. 10–11 (citing Ex. 1002, 1270–71); Prelim. Resp. 37 (citing Ex. 1002, 1270–73). In contrast, Petitioner cites Ogdon in the Petition for teaching, inter alia, segments that have “approximately the same presentation duration.” See, e.g., Pet. 27 (quoting Ex. 1004, 2:49–55). For the same reasons discussed above (see supra § II.D.3.f), and based on the present record, we disagree with Patent Owner (Prelim. Resp. 38) that this disclosure does not teach streamlets of the same length. As such, we find that Petitioner applies Ogdon in a manner that is distinguishable from the way Carmel was understood by the Examiner during prosecution of the ’138 patent. Thus, we find that the same or substantially the same art or arguments were not previously presented, so we need not proceed past the first stage of the Advanced Bionics framework with respect to Ogdon.

- Obviousness (§103) › Analogous artAnalogous artDecided for petitioner
“Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). Our inquiry begins and ends with the first test pertaining to the field of the endeavor. Patent Owner is correct that the ’138 patent is in the field of video streaming over the internet with shifting of streaming content based on network conditions. See Ex. 1001, 1:31–34. Similarly, Ogdon discloses shifting presentation content that is transmitted over the internet based on network conditions. See, e.g., Ex. 1004, 1:9–15. The only potential discrepancy appears to be whether Ogdon’s disclosed presentation content can include streaming video. And Ogdon discloses an example where a presentation version may include “real time or animated video.” Id. at 2:61– 66; see also infra § II.D.3.a (discussing Ogdon’s disclosure of video presentations). We find that Ogdon’s disclosure of transmitting real-time video as part of a presentation is the same as video streaming. Thus, we conclude that Ogdon is analogous art because it is in the same field of endeavor as the ’138 patent. For purposes of this Decision, we determine that Ogdon qualifies as prior art under 35 U.S.C. § 102(b) because Ogdon’s issue date of December 12, 2000, is more than one year before the earliest effective filing date of the challenged claims, which is April 30, 2004.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“reasonable likelihood of prevailing in showing that an ordinarily skilled artisan would have been motivated to combine Ogdon and Allen to yield this limitation. Ogdon teaches different quality versions of a presentation that may include video (see, e.g., Ex. 1004, 2:8–10, 2:30–66, 13:47–49, 22:44– 47, 24:55), and Allen expressly teaches encoding the same content at bitrates of 56 kbps, 300 kbps, and 600 kbps (see, e.g., Ex. 1005, 12:1–5). Based on these teachings, Petitioner shows sufficiently, on this record, that it would have been obvious to encode streaming video into low, medium, and high quality streams. See, e.g., Ex. 1003 ¶¶ 65–67. We also are sufficiently persuaded on this record that an ordinarily skilled artisan would have combined Allen with Ogdon to enable streaming video presentations for a variety of different available bandwidths. See, e.g., Ex. 1003 ¶ 67; Ex. 1004, code (57). In particular, Ogdon’s teaching of retrieving alternatively sized presentations based on transmission data rates supports Petitioner’s proposed combination with Allen’s teaching of encoding video at different bitrates. See Ex. 1004, code (57) (stating that a greater-sized presentation for a “higher transmission rate” has “corresponding enhanced quality of presentation” compared to a reduced-sized version for a “low transmission data rate”), 22:44–47 (stating that “as the expected amount of time for retrieving one or more presentation elements lengthens, . . . better presentation quality presentation elements may be retrieved (e.g., the presentation quality may be enhanced from limited or no animation to full animation)”). And Petitioner establishes sufficiently that an ordinarily skilled artisan reasonably would have expected success in making the combination, particularly given that Ogdon already contemplates alternative presentations for different transmission rates. See, e.g., Ex. 1003 ¶¶ 65, 67; Ex. 1004, code (57). Patent Owner’s arguments are directed to Ogdon alone and do not account for Petitioner’s proposed modification based on Allen.3 Such arguments do not show nonobviousness where Petitioner’s obviousness ground is based on a combination of references. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). Furthermore, to the extent Patent Owner argues that an ordinarily skilled artisan would not have been motivated to modify Ogdon as proposed, it fails to sufficiently explain this contention. For example, we do not read Ogdon to indicate that its presentation versions must be wholly different types of presentation materials, i.e., presentations in different languages or presentations tailored for different audiences. We also do not agree with Patent Owner (Prelim. Resp. 22–25) that Ogdon fails to teach or suggest video streaming for the same reasons discussed above. See supra §§ II.D.1, II.D.3.a. Thus, based on the present record, Patent Owner’s arguments regarding this limitation are unavailing.” slip op. at 21

“FIG. 4.” Pet. Reply 7. That is, even if “the parties do not dispute that Figure 1 applies to the Passint invention as a whole” (PO Sur-Reply 15), Petitioner has met its burden of establishing anticipation if it shows that each and every element in claim 17 is found in the single embodiment set forth in Figure 4 of Passint. Thus, although Patent Owner argues that “Petitioner never explains why Passint’s nodes 22, 24, and 26 are alleged to be router cluster nodes in a cluster router” (id.), Petitioner nevertheless can establish anticipation by showing that Figure 4 of Passint discloses router cluster nodes in a cluster router, as recited in claim 17. As Petitioner persuasively points out, contrary to Patent Owner’s contention, “the Petition does not cite Passint’s FIG. 1 as disclosing the ‘router cluster node,’” but rather, “specifically refers to Passint’s router chips 50/150 as disclosing the ‘router cluster node’ of the ‘router cluster’ of Passint’s FIG. 4.” Pet.
