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.

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.

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.

    “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.

    “Although Patent Owner argues that adding Konstaninos’s multi- channel functionality to Kamieniecki’s single-channel device would increase costs and complexity, Patent Owner overlooks that multi-channel functionality would also increase the STB’s capabilities. In any case, “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate a motivation to combine.” General Elec. Co. v. Raytheon Tech.

Furthermore, Petitioner presents preponderant evidence that the market demand was such that customers would have desired an STB with multi-channel functionality even though it would cost more than a basic STB. Pet. Reply 6–8 (citing Ex. 1010 ¶¶ 1, 11, 16, 102–104; Ex. 1032 ¶¶ 5–6; Ex. 1033, 27:6–29:23; Ex. 2013 ¶¶ 70, 108). Konstantinos expressly teaches that the “evolving market for data and programming services will demand that receivers have the capability of multi-channel tuning.” Ex. 1010 ¶ 1. Petitioner has thus established that there was market demand that would have led a POSITA to improve Kamieniecki with Konstantinos’s multi-carrier capability. See KSR, 550 U.S. at 418 (“Often, it will be necessary for a court to look to interrelated teachings of multiple patents; the effects of demands known to the design community or present in the marketplace; and the background knowledge of a [POSITA], all in order to determine whether there was an apparent reason to combine the known elements in the manner claimed by the patent at issue.” (emphasis added)). Moreover, we agree with Petitioner that Konstantinos addresses the cost and complexity issues that Patent Owner asserts are problematic. Pet. 35–36; Pet. Reply 8–9 (citing Ex. 1010 ¶¶ 102, 105–106). For example, Konstantinos teaches that breaking up the original signal into smaller subsignals decreases the required sampling rate for each band since interleaved lower-rate samplers can be used, which reduces power consumption and interference, and enables conventional digital channel selection methods to be used for fine selection of one channel from a band of channels. Ex. 1010 ¶¶ 102, 104105. In addition, Konstantinos teaches reducing cost and complexity through a single chip solution. Ex. 1002 ¶ 150; Ex. 1010 ¶ 44. Hence, we do not see the cost or complexity issues that Patent Owner mentions as barriers that would have prevented a POSITA from making the combination. Similarly unavailing is Patent Owner’s stance that Kamieniecki is satisfactory for the applications for which it is designed such that a POSITA would not seek to improve it with Konstantinos. PO Sur-Reply 8–11. Konstantinos recognizes the market demand for multi-channel functionality, so adding this capability to Kamieniecki’s single-channel device would have been a natural thing for the POSITA to pursue in light of the advantages afforded thereby. Ex. 1010 ¶ 1; KSR, 550 U.S. at 420 (“any need or problem known in the field of endeavor at the time of the invention and addressed by the patent can provide a reason for combining the elements in the manner claimed”).” slip op. at 17

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.

Accordingly, we determine Petitioner has not shown by a preponderance of the evidence that claim 15 is unpatentable in view of Rosenberg, Park, and Olwal.” slip op. at 35

    “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

    “reciting “a processor operatively coupled to evaluate a seal quality of the earpiece based on seal quality measurements made while driving or exciting a signal into the speaker located in the earpiece.” To construe this phrase, we start with the claim language itself. The claim language requires that the “processor” is operatively coupled “to evaluate a seal quality of the earpiece,” indicating that the processor evaluates seal quality. The claim also states that this evaluation is performed “based on seal quality measurements made while driving or exciting a signal into the speaker located in the earpiece,” indicating that the processor uses seal quality measurements to evaluate seal quality. The phrase “while driving or exciting a signal into the speaker located in the earpiece” modifies “seal quality measurements made,” indicating the timing of when the seal quality measurements are made, namely while (at the same time as) a signal is driven or excited into the speaker. This “while driving or exciting . . .” clause does not specify what component performs the “driving or exciting a signal into the speaker located into the earpiece.” Significantly, although the claim language states that the processor “evaluate[s] seal quality,” it does not state that the processor drives or excites the signal into the speaker. Had the applicant wanted to limit the claim in that manner, it could have drafted it to specify that the seal quality measurements are made “while the processor is driving or exciting a signal into the speaker.” The applicant, however, did not do so. Indeed, elsewhere in the claim, the language clearly specifies that certain functions are carried out by the processor, for example: • “a processor operatively coupled to evaluate a seal quality of the earpiece” (claim [1b]); • “the processor is configured to generate a visual or audio message identifying whether the at least one earpiece is properly sealed” (claim [1c]); • “the processor by way of the speaker and microphone adjusts the audio” (claim 3); • “the processor measures differences in a further sound pressure level between an ambient microphone and the [earpiece] microphone, and determines a sealing profile of the ear canal” (claim 4); • “the processor determines whether the earpiece is properly inserted . . . and generates the visual or audio message identifying compliance” (claim 5); • “the processor by way of the speaker and microphone in the earpiece performs in-situ measurement of a user’s ear anatomy” (claim 6); and • “the processor monitors changes in the ECTF to determine a sealing level of the earpiece” (claim 7). Ex. 1001, 13:25–67. Claim 1, however, does not include any comparable language specifying that the processor performs the “driving or exciting a signal into the speaker located in the earpiece.” Therefore, we find that the plain and ordinary meaning of claim 1’s language does not require that the processor itself must drive or excite a signal into the speaker.” slip op. at 19

    “We do not agree with Dr. Struck’s testimony that “[a] person of ordinary skill in the art would understand that the processor performs the ‘driving or exciting’ of the signal to the speaker” and “would not even consider any other component mentioned in claim 1 as a candidate to perform the driving or exciting.” See Ex. 2006 ¶ 46. Dr. Struck does not discuss the grammar and structure of the claim language, including the fact that the phrase “while driving or exciting a signal into the speaker” modifies “seal quality measurements” and indicates the timing of when the seal quality measurements are made (while (at the same time as) a signal is driven or excited into the speaker). See id. Dr. Struck also does not discuss the fact that claim 1 recites that the processor “evaluate[s] a seal quality of the earpiece” but does not say that the same processor “driv[es] or excit[es] a signal into the speaker located into the earpiece, instead leaving the subject of what component performs the “driving or exciting” unspecified. See id. Indeed, Dr. Struck acknowledged at his deposition that his declaration lacks an “analysis of the grammar used in the limitation of [c]laim 1” at issue here. Ex. 1027, 20:4–15. Additionally, Dr. Struck appears to assume that the “driving or exciting” must be performed by some “other component mentioned in claim 1,” but there is no requirement that the claim must specify a particular component for carrying out this function. See Ex. 2006 ¶ 46.” slip op. at 21

    “We also agree with Patent Owner that, in Petitioner’s proposed combination, the above rule that gates off the ear canal microphone would frustrate Allen’s purpose of comparing the signals from the inner and outer microphones to determine a reverse transfer function and perform a seal fit analysis. See PO Resp. 53–54; PO Sur-reply 13. In reaching this conclusion, we credit the testimony of Mr. Struck that “[w]hen this rule is in force, the Allen-Victorian combination would not be able to measure a reverse transfer function” and, accordingly, “would be incapable of performing the automatic adjustments that the Allen hearing aid can perform based on the reverse transfer function.” Ex. 2006 ¶ 114. Dr. Kyriakakis also confirmed at his deposition that, when this rule is in effect, Allen would not be able to use the reflectance method, which relies on signals from the inner and outer microphones: Q: So while the rule at Column 10, lines 19 through 22, of Victorian is being employed, Allen is not able to solve any of the problems that it solves by the reflectance method; is that correct? A: If Allen doesn’t have access to the signals, that is correct, to the two microphone signals. Ex. 2007, 63:16–23. We are not persuaded by Petitioner’s argument that Victorian’s VOX circuit would not interfere with Allen’s seal fit analysis, because Victorian states that gating off may cause microphone signals to be “blanked or substantially attenuated,” and “[s]ubstantial attenuation refers to an attenuation after which the attenuated sound does not cause any echo or tinging7 having an intolerable intensity.” See Pet. Reply 14–15 (citing Ex. 1013 ¶ 32; Ex. 1027, 120:1–8, 121:3–9). As noted above, the Petition relies on the embodiment of Victorian’s VOX that “prevents the remote sound from being detected by ear canal microphone 440,” rather than an embodiment that simply attenuates that sound. See Pet. 46; Ex. 1002 ¶ 152; Ex. 2007, 61:2–16. Petitioner’s shift to relying on a different embodiment of Victorian that “substantially attenuat[es]” the sound rather than blocking it is a new argument that is presented for the first time in Petitioner’s Reply, and we therefore need not consider it. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019), at 73 (“Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.”). 8 Moreover, 7 The quoted portion of Victorian refers to “tinging,” but this appears to be intended to refer to “ringing.” For example, the previous sentence states that “[b]lanking refers to a substantially complete blockage of a sound, or in other words, that a detected sound is practically ignored by processor 460 such that it does not cause any echo or ringing which is audible by an ear.” See Ex. 1013 ¶ 32 (emphasis added). 8 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated.” slip op. at 52

    “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
