“establishes that the subject matter of independent claim 19 would have been obvious in view of Whitehead. Claim 19 recites “an aggregator having a memory and a processor, the processor adapted for . . . providing an output signal including data indicative of the selection and of user data.” Ex. 1001, 15:51–16:3. As discussed above (Section II.C.2), we construe claim 19 as requiring a signal including both “data indicative of the selection and of user data.” Accordingly, we consider whether Petitioner has shown that Whitehead teaches or suggests that the “aggregator” “provid[e] an output signal including” both “data indicative of the selection and of user data.”” slip op. at 46

“Cristofalo’s “user identifiers” represent data about users that Cristofalo’s system uses to “select a specific media object” (advertisements) from received “multi-object programming data.” Cristofalo at ¶ [0048]. For example, a user identifier may indicate that a given user is a Coca-Cola drinker, and when the receiving system receives the multi-object programming data it can select a particular media object out of several possible media objects (e.g., a Pepsi advertisement) to push to the user. Id. This user data exists independently of, and does not relate to, any particular media stream or streams. See Goodrich PO Resp. Decl. at ¶ 135. Petitioner seems to recognize this when tersely referring to “user identifiers” as “data,” not “data relating to a plurality of streams.” Pet. at 71.

“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 contends, “[a] POSITA would have modified Whitehead’s mixing server 130 to incorporate Marcus ’904’s algorithm (running on Marcus ’904’s receiver) for receiving, selecting, ordering, and assembling different media streams (both for content and advertising).” Pet. 33. 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.

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).

“reasonable expectation of success in achieving the proposed Le-Kvaløy combination. Our conclusion is supported by Dr. Atlas’s testimony that one of ordinary skill “would have been able to adapt Le’s computer unit 15 to wirelessly communicate with Kvaløy’s ear terminal, as Le itself suggests.” Ex. 1002 ¶ 110. We also credit Dr. Atlas’s testimony that one of ordinary skill would have been able to “pass the signal from the outer microphone [of Kvaløy] (which replaces Le’s environmental microphone in the combination) continually to Le’s computer unit through the digital interface.” Id. ¶ 112; see also id. ¶¶ 113–114. We further agree with and find credible Dr. Atlas’s testimony that one of ordinary skill would have been aware of the potential for feedback, echo, and ringing, and would have been able to implement solutions to address this issue.

“3. Motivation to Combine Le and Kvaløy a) The Parties’ Arguments Relying on the testimony of Dr. Atlas, Petitioner argues that one of ordinary skill “would have been motivated to combine the teachings of Le and Kvaløy, and would have had a reasonable expectation of success in doing so.” Pet. 18 (citing Ex. 1002 ¶ 93). According to Petitioner, Le emphasizes the desire for the system to be unobtrusive and blend in with the user’s appearance, and discloses that computer unit 15 can be implemented as a cellular telephone with wireless connections for microphones 36 and 38. Id. (citing Ex. 1005 ¶¶ 5, 9, 31, 33, 42). Petitioner also contends that Le is “concerned with properly recognizing voice commands that initiate recording in noisy environments.” Id. (citing Ex. 1005 ¶¶ 23–24). In view of these disclosures, Petitioner argues, one of ordinary skill would have been motivated to look for ways to implement Le’s system with a wireless connection to the microphones 36 and 38 and an ability to input audio commands in noisy environments, while making the system more unobtrusive. Id. at 18–19 (citing Ex. 1002 ¶ 99). Petitioner argues that this motivation would have led one of ordinary skill to Kvaløy. Pet. 19 (citing Ex. 1002 ¶ 99). According to Petitioner, one of ordinary skill “would have recognized that Kvaløy’s ear terminal was compatible with and even advanced Le’s disclosed objectives and be as good or superior to Le’s earpiece 30” for the following reasons: 1. Kvaløy’s ear terminal is analogous to Le’s earpiece 30 because both are configured to exchange audio signals with other devices. Id. at 20 (citing Ex. 1002 ¶ 103). 2. Kvaløy’s ear terminal would be less obtrusive and better blend in with the user’s natural appearance than Le’s wired earpiece 30. Id. (citing Ex. 1002 ¶ 104). 3. Kvaløy’s inner microphone M2 would provide an equivalent or superior voice signal to Le’s personal microphone 36 for Le’s natural voice commands to computer unit 15 because it is less susceptible to noise. Id. (citing Ex. 1002 ¶ 105). 4. Kvaløy’s outer microphone M1 for picking up ambient sound so that the user can speak with other people would be as effective as Le’s belt-worn environmental microphone 38 without the obtrusiveness of having to carry around a separate microphone or wear it on a belt. Id. at 20–21 (citing Ex. 1002 ¶ 106). 5. Le’s recording of ambient sound for later recall would have been an obvious use for Kvaløy’s ear terminal microphones. Id. at 21 (citing Ex. 1002 ¶ 107). Accordingly, in Petitioner’s combined Le-Kvaløy system, “Kvaløy’s ear terminal would replace Le’s earpiece and Le’s environmental microphone such that Kvaløy’s outer microphone would replace Le’s environmental microphone, and Kvaløy’s inner microphone would be used to pick up the user’s speech instead of the personal microphone.” Pet. 21–22 (citing Ex. 1002 ¶ 109). Petitioner asserts that “wireless headsets for mobile devices were common in the 2007 timeframe,” and one of ordinary skill “would have been able to adapt Le’s computer unit 15 to wirelessly communicate with Kvaløy’s ear terminal, as Le itself suggests.” Id. at 22 (citing Ex. 1002 ¶¶ 110–111).” slip op. at 18

“using its earpiece.” Id. at 3–4 (citing Ex. 1007, code (57), ¶¶ 2, 6, 16). “Accordingly,” Petitioner contends, “a user of the Le-Victorian combination could still hear the surrounding environment, including the conversation, in his/her other ear even when the ear canal speaker is off.” Id. at 4. “Furthermore,” according to Petitioner, “as long as the ear canal speaker is off, there is no feedback loop between Victorian’s ear canal microphone and ear canal speaker, and thus no risk of the echo, ringing, or feedback that [Patent Owner] complains about.” Id. Petitioner also argues that, in the proposed combination, it would have been obvious to modify Victorian’s ear-level device 110 to pass the signal from the external microphone to both the ear canal speaker and continually to Le’s computer unit, so that the external microphone signal is transmitted to the remote device independent of whether the external microphone signal was also transmitted to the ear canal speaker. Pet. Reply 4–5 (citing Pet. 18; Ex. 1002 ¶¶ 114–115). In this configuration, Petitioner asserts, Victorian’s ear-level device would “transmit the external microphone signal to Le’s computer unit to record conversations independent of whether the signal was also transmitted to the ear canal speaker.” Id. at 5. Thus, according to Petitioner, “there would be no need to ‘completely redesign Victorian’s VOX circuit 430’ or to ‘chang[e] all its existing rules.” Id. (citing PO Resp. 28). Petitioner further contends that Victorian discloses a rule in which “ambient sound gating module 421 is off, occluded sound gating module 441 is on, and remote sound gating module 451 is off” which, when combined with Petitioner’s proposed modification to provide an independent path from the external microphone to the computer unit, would allow the combined system to record conversations. Id. Petitioner also disagrees with Patent Owner’s argument that, due to technical challenges, one of ordinary skill would not have had a reasonable expectation of success in making the proposed Le-Victorian combination. Pet. Reply 7–8. Petitioner argues that Patent Owner does not argue that Petitioner’s proposed independent path modification would have been beyond the level of ordinary skill, and that the features Patent Owner points to, such as incorporating components into a “small earpiece” that operates within a “power budget,” are “unclaimed.” Id. at 7. Additionally, Petitioner asserts that Victorian itself refutes Patent Owner’s arguments about purported technical limitations “because Victorian discloses an earpiece with an in-ear canal form factor including the components that [Patent Owner] alleges would be ‘difficult to miniaturize,’” and Victorian is presumed to be enabling. Id. (citing Ex. 1007 ¶¶ 13, 29, Figs. 3, 4). Petitioner also contends that Patent Owner’s argument about “the alleged absence of commercialized consumer electronics” is “irrelevant.” Id. at 8. Moreover, Petitioner argues, “the ’839 patent itself admits the absence of these purported technical challenges,” because “despite having the same microphone and speaker placement as Victorian and the ability to record conversations with a ‘user-defined verbal activation message,’ the ’839 patent does not even mention feedback, echo, or ringing as a problem to solve.” Id. Furthermore, Petitioner argues, even if the Le-Victorian combination did not allow recording of conversations, that would not render the combination “inoperable.” Pet. Reply 10. According to Patent Owner, Le discloses uses for its system that do not require simultaneous recording of the user and another speaker, including situations “when the user is alone” and an embodiment “in which the audio information received ‘between’ two commands is stored (such as ‘start recording’ and ‘stop recording’).” Id. (citing Ex. 1006 ¶¶ 36, 37). “Thus,” Petitioner contends, “only some features Le describes would be less effective, which does not show inoperability.” Id.” slip op. at 24
