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.

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. Corp., 983 F.3d 1334, 1351 (Fed. Cir. 2020) (citing Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006)). 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

Because we need not expressly construe any claim terms, we do not construe any terms of the ’662 patent. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Matal, 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am.

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedReference is prior artDecided for petitioner

    “date of the ’662 patent, Ho is not a “printed publication” within the meaning of 35 U.S.C. § 311(b). PO Resp. 30–33; PO Sur-reply 15–16. 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

    “A person having ordinary skill in the art would have combined Aoki’s teaching of using user-identification information as part of the request for an advertisement with Ho’s system, which also teaches a client device sending information to a server to request hot spot information, such as advertisements. See Ex. 1003 ¶¶ 103–107, 111, 114, 117. Because both Ho and Aoki are directed to improvements in game design and monetization from using advertisements (id. ¶ 106; Ex. 1004, 1:26–28; Ex. 1005 ¶¶ 6–8), a person having ordinary skill in the art would have looked at both Ho and Aoki and combined the relevant features with a reasonable expectation of success (Ex. 1003 ¶¶ 103, 106, 117). A person having ordinary skill in the art would have appreciated that using Aoki’s teaching of sending user-identification information with Ho, which includes sending information with a request for information relating to interactive information elements (hot spots), allows for targeted advertisements, which was a known advantage in advertising. Id. ¶ 117; Ex. 10089 ¶¶ 54–55 (describing advantages of targeted advertising).” slip op. at 26

    “PO Resp. 9. Patent Owner asserts “a POSA would have understood the plain and ordinary meaning of the term ‘acoustic signal’ [is] a signal that is transmitted as a sound wave through the ambient environment.” Id.; Ex. 2003 ¶ 25. Patent Owner therefore asserts a POSA would have understood the claimed “frequency modulated ECG acoustic signal” is a signal that is transmitted as a sound wave through the ambient environment, [and excludes] signals transmitted by electronic or wireless radio means, because claim 1 requires the acoustic signal to be “received from a built-in microphone of the smartphone.” PO Resp. 9; Ex. 2003 ¶ 26. Petitioner responds by asserting that “a POSITA would have understood that acoustic transmission is a form of wireless transmission.” Pet. Reply 24; Ex. 1021, 46:7–47:5 (citing the Jafari Deposition where Dr. Jafari stated “in the event of an acoustic signal, there is no need to connect a wire”) Having considered the entire record, we do not find there is a substantive dispute over the term “acoustic signal” as both Patent Owner and Petitioner agree that acoustic signals include wireless signals transmitted as a sound wave through the environment. We will apply this understanding in our further analysis.” slip op. at 7

    “A person of ordinary skill in the art (“POSITA”) would have had either (1) at least a bachelor of science in electrical engineering, mechanical engineering, or biomedical engineering, or a related discipline, with at least two years of relevant multidisciplinary work experience designing wearable devices and/or sensors for measuring physiological signals or parameters of mammals, or (2) a medical degree and at least five years of relevant work experience designing wearable devices and/or sensors for measuring physiological signals or parameters of mammals.” slip op. at 5

    “interference of sound waves was a known phenomenon at the time of the invention does not demonstrate that the ordinary artisan would have had reason to select particular carrier frequencies for the ECG acoustic signals that avoided human voice frequencies in the absence of any disclosure that such frequencies were known to interfere. Rather, we agree with Patent Owner that this is hindsight reasoning because until the ’882 patent pointed out this concern in the context of claim 1, there is no indication the prior art recognized that human voice interference was an issue.” slip op. at 26

    “that Vyshedskiy’s disclosure of a list of preferred carrier frequencies represents a permissible “obvious to try” situation. In KSR, the Supreme Court stated that a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103. KSR, 550 U.S. at 421. And simply because the prior art “discloses a multitude of effective combinations does not render any particular formulation less obvious.” Merck & Co. v. Biocraft Labs., Inc., 874 F.2d 804, 807 (Fed. Cir. 1989). The instant facts represent a situation where, at the time of invention in 2010, it would have been obvious to try the known carrier frequencies of Vyshedskiy for modulation of the acoustic ECG signal of Albert in the claimed frequency range of 6 kHz to 20 kHz because these carrier frequencies would have been obvious alternatives to try to address Vyshedskiy’s disclosed design need for simultaneous measurement of heart sound auscultation and ECG heart cycle.

    “As a general rule, ‘[u]nless the steps of a method [claim] actually recite an order, the steps are not ordinarily construed to require one.’” Mformation Techs., Inc. v. Research In Motion Ltd., 764 F.3d 1392, 1398 (Fed. Cir. 2014) (quoting Interactive Gift Express, Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001)). “However, a claim ‘requires an ordering of steps when the claim language, as a matter of logic or grammar, requires that the steps be performed in the order written, or the specification directly or implicitly requires’ an order of steps.” Id. (quoting TALtech Ltd. v. Esquel Apparel, Inc., 279 F. App’x 974, 978 (Fed. Cir. 2008)). Our preliminary discussion in the Decision Granting Institution states that “logic dictates that a voice timer must be active before something can happen ‘during a voice timer,’” but the Decision Granting Institution notes that the claims can be read in different ways, e.g.: “(a) changing a mixing gain at some point in time while the voice timer is active, or (b) maintaining an adjusted mix throughout a voice timer ‘pending voice activity.’” Paper 13, 15. On the full record, we determine the latter reading is correct; the claims do not require performing the “activating/activate” step before the “adjusting/adjusts” step, nor that a singular act of “adjusting/adjusts” must occur “during” a voice timer. slip op. at 10

    “based on Kvaløy’s additional teachings of a protective earplug that protects a user’s hearing by sealing a user’s outer ear canal while allowing selected sounds to pass through. Pet. 29–30 (citing Ex. 1009 1:39–44, 3:40–46, 3:50–52, 4:22–26, 4:38–41, Fig. 1; Ex. 1002 ¶¶ 143–156). Petitioner also contends a person of ordinary skill would have been motivated to combine the teachings of Rosenberg and Kvaløy because, among other things, the references teach similar devices designed to protect users’ hearing and employing Kvaløy’s sealing section to provide full sound isolation in Rosenberg’s device would have improved Rosenberg’s hearing protection. Pet. 31–32. Patent Owner does not separately address or rebut Petitioner’s contentions for claim 4. We agree with Petitioner that the cited portions of Kvaløy satisfy claim 4, and we determine Petitioner has adequately articulated reasons a person of ordinary skill would have been motivated to combine the teachings of Rosenberg and Kvaløy, including to improve the hearing protection of Rosenberg’s device with the Kvaløy’s teachings of a sealing section. Accordingly, we determine Petitioner has proven by a preponderance of the evidence that claim 4 would have been obvious in view of the combined teachings of Rosenberg and Kvaløy.” slip op. at 27

Even if these arguments were timely, Petitioner’s arguments are unpersuasive because Olwal describes a user interface for use with a desktop computer, which is well removed from the relevant field of endeavor, and Petitioner has not adequately established that Olwal’s teachings are reasonably pertinent to the problems with which the inventor of the ’244 patent was involved. 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
