“The parties’ definitions are similar, although we observe that Patent Owner proposes that the person of ordinary skill would have a bachelor’s degree or an equivalent or professional experience, whereas Petitioner proposes that such a person would have both a degree and experience. Neither party presents any arguments relating or referring to the level of ordinary skill in the art. 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.

We adopt Petitioner’s assessment of the level of skill in the art. Petitioner’s assessment is supported by the testimony of Dr. Almeroth and is consistent with the ’753 patent and the asserted prior art. However, our obviousness analysis would be the same under either party’s assessment. See Ex. 2014 ¶ 17 (Patent Owner’s declarant, Dr. Goodrich, stating that “I note that my definition of a POSITA is similar to that of Dr. Almeroth” and “My opinions in this declaration would not change were I to adopt the definition of a POSITA offered by Dr. Almeroth.”).” slip op. at 11

Petitioner supports this contention by articulating the following reasons for the asserted modification of Whitehead’s mixing server 130 to incorporate Marcus ’904’s algorithm: “makes it more likely the system will identify content best suited for a particular user,” “allows for more targeted advertising and/or an opportunity to maximize revenue,” “improves Whitehead’s ability to target content and advertising to a particular user,” “would unlock new revenue sources for Whitehead,” “Marcus ’904’s content selection and concatenation algorithm improves Whitehead’s efficiency,” “[b]oth Whitehead and Marcus ’904 generate custom media programming based on a user profile,” “incorporating Marcus ’904’s teachings would not require redesigning Whitehead’s architecture and instead merely supplements Whitehead’s disclosure,” and “Petitioner’s proposed modification can be implemented entirely in software and does not require any hardware modifications.

“anticipated by Rao. Pet. 1, 30–31, 33–42. We have reviewed Petitioner’s arguments for each of those dependent claims. See Pet. 30–31, 33–42. For each of those dependent claims, the Petition appears to only argue a theory of obvious. That is, the Petition never states that the additional limitation is disclosed by Rao. See id. For example, claim 26 depends from claim 1 and further recites “wherein the policy is based on a background service class.” Ex. 1001, 112:49–52. We reproduce Petitioner’s arguments directed to claim 26 below: Rao’s policies 520 may “define prioritization” for network packets “based on whether an application is running in the foreground or the background.” [Ex. 1002] ¶ 182; id. ¶¶ 38–43, 180, 182, 188–89, 193, Figs. 5A, 5B. Each packet “may be placed and arranged in a priority order respective to all other . . . packets to provide a packet by packet prioritization across all applications 338a-338n and . . . network packets.” Id. ¶ 191. It would have been obvious to determine and apply a policy assigning a specific priority to packets associated with background applications, supra [1e]-[1f], and Rao thus discloses or renders obvious assigning a priority to network communications based on whether they are characterized as background services (class of services associated with application(s) running in the background of client 105), EX-1015 ¶¶195-96; supra [1e], [1f].

See id. Similar arguments are presented for the other claims. See Pet. 30–31, 35–42. Because the Petition does not sufficiently show how the additional limitations recited in claims 20, 26, 58, 64, 165, and 169 were disclosed by Rao, Petitioner has not shown by a preponderance of the evidence that claims 20, 26, 58, 64, 165, and 169 were anticipated by Rao.” slip op. at 28

“Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” is too narrow. Although Patent Owner points to various parts of the ’518 patent as supporting its restrictive proposal, other parts of the patent are not so limited. For example, the patent’s technical field and summary are not limited to coaxial cable, and the patent discusses twisted pair wiring and satellite communications as media that can be used. See, e.g., Ex. 1001, 1:27–29, 3:33–35, 3:49–50, 3:67–4:3, 5:61–6:3, 8:20–23, 9:28–33. Accordingly, we adopt the following level of ordinary skill in the art for use in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to four years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find that this skill level is consistent with the problems and solutions identified in the ’518 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date. Lynk Labs, Inc. v. Samsung Elecs. Co., 125 F.4th 1120, 1127 (Fed. Cir. 2025). Thus, Petitioner asserts permissible grounds of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–20 are unpatentable under 35 U.S.C. § 103(a) on the basis of Ho, which is a prior art printed publication, and either Aoki or Kim.” slip op. at 11

“We have authority, acting on the designation of the Director, to determine whether to institute an inter partes review under 35 U.S.C. § 314 (2024) and 37 C.F.R. § 42.4(a) (2024). Inter partes review may not be instituted unless “the information presented in the petition filed under section 311 and any response filed under section 313 shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). “When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a). For the reasons set forth below, upon considering the briefing and the evidence of record, we determine that the information presented in the Petition establishes a reasonable likelihood that Petitioner will prevail with respect to at least one of the challenged claims. Accordingly, we institute inter partes review on all of the challenged claims based on all of the grounds identified in the Petition.” slip op. at 2

“Petitioner argues that a person having ordinary skill in the art “would have had a (1) bachelor’s degree in electrical engineering, computer engineering, computer science, or a comparable field of study, and (2) approximately two to three years of practical experience with video and/or image processing or coding.” Pet. 25–26 (citing Ex. 1003 ¶¶ 60–63). Petitioner further argues that “[a]dditonal experience can substitute for the level of education, and vice-versa.” Id. at 26 (citing Ex. 1003 ¶¶ 60–63). Petitioner also identifies knowledge that a person having ordinary skill in the art would have. Id. (citing Ex. 1003 ¶ 64). Patent Owner states that it “has applied Petitioner’s [person having ordinary skill in the art] for the sake of this Response.” Prelim. Resp. 21. Because Petitioner’s proposed level of ordinary skill in the art is consistent with the field of the invention of the ’991 patent and not disputed by Patent Owner, we adopt Petitioner’s formulation of the person having ordinary skill in the art.7” slip op. at 9

“1. Spatial Coding Petitioner argues that “spatial coding” means “coding in the spatial domain.” Pet. 28. According to Petitioner, the specification of the ’991 patent “describes spatial coding as the coding (e.g., quantizing and entropy coding) of pixel values in the spatial domain ‘without transform,’ but without limiting it to a particular algorithm or technique.” Id. (citing Ex. 1001, 5:6–23, Fig. 4). “Patent Owner does not contest Petitioner’s construction for the sake of this [Patent Owner Preliminary Response], but reserves the right to challenge this construction in the event of institution.” Prelim. Resp. 21. Accordingly, for purposes of this Decision, we adopt Petitioner’s undisputed construction.” slip op. at 11

“3. “The Difference Signal” (Claims 13 and 14). Petitioner argues that claims 13 and 14 “contain a drafting error that recites ‘the difference signal,’ without antecedent basis.” Pet. 29. According to Petitioner, a person having ordinary skill in the art “would have understood ‘the difference signal’ in these claims to mean ‘a difference signal representing differences between sample values of a predicted block of data and values for an original input block’ as recited in limitation [1a] of claim 1.” Id. For purposes of its Preliminary Response, Patent Owner “agree[d] with Petitioner’s construction of ‘the difference signal’ in Claims 13 and 14.” Prelim. Resp. 24. Accordingly, for purposes of this Decision, we adopt Petitioner’s undisputed construction.” slip op. at 11

“predictably improved Sauve’s quick pick interface, and would have promoted space efficiency and conveyed order more clearly. Id. at 59–60 (citing Ex. 1003 ¶ 159). Petitioner further argues that the combination would have exploited spatial memory and more efficient use of screen space and, thus, would have been a differentiator among competing web browsers. Id. at 60–61 (citing Ex. 1003 ¶¶ 160–162). Petitioner argues that a skilled artisan would have had a reasonable expectation of success in making the combination because GUIs, web browsers, and simulated 3D environments were all well-known technologies that had been demonstrated successfully in the real world. Id. at 61 (citing Ex. 1003 ¶ 163). Dr. Fuchs’ testimony has rational underpinning, is logical and well-reasoned, and, accordingly, we give it substantial weight.” slip op. at 64

“reference teaches away “when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” Gurley, 27 F.3d at 553. We have considered the portions of Sauve and Tsuda cited by Patent Owner and Dr. Schaefer, and find nothing that would discourage or lead in a direction divergent from the path taken by the inventor. Other than repeating Patent Owner’s argument that Sauve and Tsuda provide drastically different solutions for moving from one active window to another, Dr. Schaefer does not explain why he concludes that the solutions teach away from one another or point to evidence to support that conclusion.
