“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. Accordingly, Cristofalo’s “user identifiers” are not the claimed “data related to the plurality of media streams.” Goodrich PO Resp. Decl. at ¶ 136.” slip op. at 73

“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. Cir. 1995) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). 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. Indeed, Whitehead acknowledges that such modifications are possible. EX1003 at 19:64-20:6, 22:26-40.” Id. at 33–35 (citing Ex. 1002 (Almeroth Decl.) ¶¶ 110–115) (emphasis omitted).

Pet. 9; Ex. 2015; Ex. 2025, 31–47. Instead, the district court adopted a “plain-and-ordinary meaning” construction, which Patent Owner proposed.

“In our Institution Decision, we stated that we “will give the term ‘signal path’ its ‘plain and ordinary meaning’ and not limit it only to analog components, as the district court found and the parties agree.” Inst. Dec. 11. Given that the parties continue to agree on this point, we see no need to depart from the construction we adopted in our Institution Decision. Moreover, applying Revvo, we find that Petitioner had a sufficient reason for advancing the broader, court-adopted construction in this IPR for the same reasons as discussed above. In this proceeding, the dispute between the parties concerns the application of this and the surrounding claim language (i.e., “in the receiver signal path,” “in the signal path”) to the disclosures in Behbahani. See PO Resp. 43–45. Therefore, we will provide further discussion in the context of the parties’ arguments regarding Behbahani below. However, we agree with Patent Owner’s plain reading of the claim language to the extent it requires adjusting an impedance and/or bias current of a circuit while it is in the signal path.

“Patent Owner’s arguments generally fail to address why Behbahani’s Variable Bandpass Filter Block does not teach the recited “plurality of circuits [comprising/including] . . . a filter,” and instead focus on why the low-pass and high-pass filter circuits do not teach the limitation, which is not Petitioner’s position. As stated above, we agree with Patent Owner’s plain reading of the claim language – i.e., that it “requires adjusting the bias, in or of a circuit.” See PO Resp. 49. However, Patent Owner’s reading of the claim does not persuasively address why the Variable Bandpass Filter Block does not teach the recited “circuit.” We have reviewed Dr. Larson’s cited testimony and disagree with Patent Owner that he provided “a well-supported opinion . . . as to why a [person of ordinary skill in the art] would not understand the entire bandpass box to be a single ‘circuit,’ or to reflect variation in ‘an impedance’ or ‘a bias’ in the claims.” Sur-reply 4 (citing Ex. 2020 ¶¶ 46–48, 71, 74–83). Dr. Larson testifies that the ’330 patent (which has the same specification as the ’164 patent) “teach[es] these adjustments [that dynamically change operating parameters] as changes effected in a single circuit block.” Ex. 2020 ¶ 46 (citing, e.g., Ex. 1001, Figs. 8A, 9A, 8:20–25, 8:36–39, 9:36–59, 10:1–18 (emphasis added)). Dr. Larson does not provide further explanation as to what he means by a “single circuit block,” but relies on Figures 8A and 9A, which show a “function block,” and other disclosures referring to a “function block.” See id. There is no dispute that the recited “circuit” in the receiver signal path is referring to these “function blocks.” See Tr. 22:20–23:4. The ’164 patent states that Figure 8A, which includes function block 820, is “an embodiment of the present invention” 8:28–30. Similarly, Figure 9A, which includes function block 920, “illustrate[s] one of the possible power saving techniques.” Id. at 3:41–42. The ’164 patent describes that “[f]unctional block 820 . . . may be a filter, mixer, amplifier, or other circuit or circuits in a wireless transceiver or other electronic circuits or system.” Id. at 8:30–33 (emphasis added). Based on these disclosures, we are not convinced that Function Block 820 or 920 cannot include multiple filters in a Variable Bandpass Filter Block, or that Behbahani’s Variable Bandpass Filter Block does not teach the recited “circuit.” Dr. Larson also relies on Figure 6 of the ’164 patent to conclude that” slip op. at 45

“Owner’s] settled expectations in long-standing patent rights, and Office policies and efficiency.” Id.; see id. at 25–26.

In the Institution Decision, we were not persuaded by these arguments. Inst. Dec. 15–22. Patent Owner argues that in Ecto World, LLC v.

However, Ecto World was designated precedential on May 19, 2025, and our Standard Operating Procedure 2 provides that “[a] precedential decision is binding Board authority in subsequent matters involving similar facts or issues.” SOP2, 7 (emphasis added). Therefore, re-evaluation under Ecto World does not appear to be appropriate under the circumstances here. Patent Owner also argues that proceedings can be properly dismissed post-institution in the Director’s discretion. Sur-reply 26. In support, Patent Owner cites to Hulu LLV v.

“3. Motivation to Combine Buibas and Sinyavskiy Petitioner argues that “it would have been obvious to partition Buibas’[s] spiking networks according to the specific techniques disclosed in Sinyavskiy” for multiple reasons.

First, Petitioner asserts, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to parallelize task execution on the robot and improve learning capabilities (e.g., through faster learning, greater computing efficiency, and task-specific learning models) of the Buibas mobile robotic apparatus as described by Sinyavskiy and discussed by Dr. Janet.” Id. (citing Ex. 1003 ¶ 64). Second, Petitioner contends, “partitioning Buibas’[s] robotic brain as suggested by Sinyavskiy would have beneficially expanded the range of tasks that the robot could perform by dedicating partitions to specialized tasks.” Id. at 13– 14 (citing Ex. 1006 ¶¶ 12, 185, 188, Fig. 6A; Ex. 1005 ¶¶ 71–72, 85, 92, 179–205; Ex. 1003 ¶ 65). Third, Petitioner argues, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to permit unused partitions or unused resources in the partitions to be reassigned for different tasks,” which would allow for a network processing apparatus that has increased processing capability for the same network capacity while also having a lower cost, size and power consumption. Id. at 14 (citing Ex. 1006 ¶¶ 190–192, 105, 34, code (57); Ex. 1003 ¶ 66). Fourth, Petitioner argues that “Buibas briefly mentions that its spiking neural networks can be partitioned but discloses little detail about the partitioning,” which would invite one of ordinary skill to turn to other references, such as Sinyavskiy, for additional detail on how to implement partitioning. Pet. 14–15 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 67). Fifth, Petitioner asserts, combining Buibas and Sinyavskiy would merely “involve[] the application of known techniques (e.g., Sinyavskiy’s partitioned neural network) to a known system (e.g., Buibas’[s] mobile robot and robotic brain) to yield predictable results (e.g., Buibas’[s] robot using a spiking neural network partitioned as taught in Sinyavskiy),” particularly because “the partitioning of the Buibas neural network is reminiscent of Recurrent Fuzzy Neural Networks (RFNNs) that were already commonplace at the end of the 1990’s.” Id. at 15 (citing Ex. 1003 ¶ 68). Finally, Petitioner contends, the proposed combination merely involves “use of known techniques (e.g., Sinyavskiy’s partitioned neural network) to improve a similar system (e.g., Buibas’[s] mobile robot and robotic brain).” Id. (citing Ex. 1003 ¶ 69). Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70).

“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. Cir. 1995) (citing Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed.

“We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed.

“We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra. Having decided proper constructions for the disputed terms, we proceed in our analysis to consider the parties’ arguments concerning the challenge grounds. In the following sections, we apply the plain meaning of the claim terms, and as necessary, specify what the plain meanings are.” slip op. at 23

“C. Level of Ordinary Skill in the Art Petitioner contends as follows: A POSITA8 would have had a bachelor’s degree in electrical engineering, computer engineering, or a similar discipline, and three to four years of experience working in signal processing and/or communication systems/networks. Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art. We adopt and apply Petitioner’s proposed skill level because it is consistent with the problems and solutions identified in the ’690 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.

“We agree with Patent Owner and find that “computer network protocols” is correct in light of the ’072 patent’s disclosure and claim 1. In particular, the ’072 patent teaches that it “generally relates to [USB] connectivity between, for example, mobile consumer devices and vehicle electronic systems.” Ex. 1009, 1:21–23. And the ’072 patent’s teachings focus on common network components (e.g., hub, bridge, ports) and common networking concepts (e.g., master/slave network architecture and bridging) which are used in the USB context, rather than detailed aspects (e.g., signal timing, signal levels, power levels) of the USB protocol. See generally Ex. 1009; see also Ex. 1084, 103:21–104:2, 104:24–105:4; Pet. Reply 4 (citing Ex. 1084,7 100:17–101:12 (acknowledging that Dr. Houh testifies that one of ordinary skill in the art “would know basic USB concepts like bridging, master/slave architecture, etc.”), 102:3–8, 103:21– 104:2, 104:24–105:4). Likewise, claim 1 repeatedly recites “USB,” but does so to identify that all of the components of the data system (i.e., USB ports, USB hub, USB bridge, USB host, USB multiplexing switches) employ the USB protocol. Ex. 1009, 9:15–10:18. As the ’072 patent teaches, “USB 7 Houh Deposition Tr. (2024/12/18, Day 1). technology . . . [wa]s commonly available, familiar to the end user, cost effective and ubiquitous.” Id. at 1:35–37. Thus, although the ’072 patent is taught in the USB context, “computer network protocols” concepts are the focus. For these same reasons, we find unavailing Petitioner’s argument that one of ordinary skill in the art “would have been well-versed in USB standards (including the USB 2.0 and 3.0 Specifications and the OTG Supplement) and the design/deployment of USB hosts, USB devices, and USB hubs, including suitable environments for USB systems.” Pet. 26.” slip op. at 11

“Here, Petitioner argues that “embedded USB host” means “USB host physically embedded in a vehicle.” See Pet. 27–28. “Patent Owner does not contend that any claim construction is required.” PO Resp. 5. We agree with Patent Owner that we do not need to construe any term to resolve the disputes between the parties. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

“that the asserted objective evidence is tied to a specific product that ‘embodies the claimed features, and is coextensive with them.’” Id. (quoting Brown & Williamson Tobacco Corp. v. Philip Morris, Inc., 229 F.3d 1120, 1130 (Fed. Cir. 2000)). In other words, “[a] presumption of nexus requires both that the product embodies the invention and is coextensive with it.” Id. at 1211 (citing Brown, 229 F.3d at 1130). Patent Owner fails to show either of these requirements. First, Patent Owner argues that in his Supplemental Declaration, Dr. Houh “provides on a per limitation basis how [Patent Owner]’s dual role hub meets all limitations of claim 1.” PO Resp. 73 (citing Ex. 2019 ¶ 136). Notably, Patent Owner cites to a single paragraph in this declaration, without providing any specific arguments in its Response that its product practices claim 1. Id. Rather, Patent Owner incorporates its arguments by reference, which is not permitted. See 37 C.F.R. § 42.6(a)(3) (“Arguments must not be incorporated by reference from one document into another document.”). Thus, we do not consider these arguments, and we are not persuaded that Patent Owner’s product practices claim 1.

“Patent Owner contends that a person of ordinary skill in the art of the ’251 patent would have had: (1) the equivalent of a four-year, B.S. degree from an accredited institution in computer science, computer engineering or an equivalent field; (2) approximately two years of professional experience with Internet-based video delivery systems; and (3) working proficiency with network architecture, including Internet-hosted server-client systems, and with computer programming.

“Mr. Lett testifies that Mahajan “allows for its server media abstraction module to be located in a processing device that may not typically be labeled a ‘server,’ such as remote control 14 of Danciu.” Ex. 1198 ¶ 9 (citing Ex. 1102 ¶ 162; Ex. 1114 ¶ 17). Yet, both Petitioner and Mr. Lett fail to explain how or why a person of ordinary skill in the art would take the distributed nature allowed by Mahajan and completely flip its teachings to put a client or remote device process on a server device. Mr. Lett further fails to explain how or why one would want to move Mahajan’s abstraction layer in the first place. Although Mahajan teaches that its system can operate in a distributed environment, based on the explicit disclosure of Mahajan and its examples, we do not understand “distributed” to mean that (i) the server processes can occur on client devices and (ii) that client processes can occur on server devices. See Ex. 1114 ¶¶ 51, 58, 60, 61, 76, 77. Rather, we understand “distributed computing environments” to encompass “an environment where tasks are performed by remote processing devices that are linked through a communications network” because that is what is taught in Mahajan. Id. ¶ 58. Our understanding is supported by the testimony of Mr. Lett. See Ex. 1198 ¶ 8 (reciting the explicit disclosure in Mahajan). It is clear, based on the plain reading of Mahajan, that the distributed environment indicates that server 202 and client 204 could be located in different locations, but would be linked through a communications network where user-command 230 flows from client 204 to server 202. See Ex. 1114 ¶ 35, Fig. 2. At no point does Mahajan teach or even suggest that user-commands 230 would flow from server 202 to client 204 as proposed by Petitioner. Additionally, we find insufficient reason in the record to explain Petitioner’s argument appears to be based completely on hindsight bias created in view of the challenged claims. Therefore, we find little credibility in Mr. Lett’s testimony regarding the change or in Petitioner’s position. To the contrary, we find Dr. Wicker’s testimony to be credible because it is supported by the disclosures in both Mahajan and Danciu. Specifically, we agree with Dr. Wicker, who testified that Mahajan does not describe an abstraction layer as ever being on “a server in the network.” See Ex.1197, 18:21–24. We also find Dr. Wicker’s testimony credible when he explained that even if Mahajan’s abstraction layer were implemented on a server in a network as posited by Petitioner, it still would not result in the claim mapping proposed by Petitioner. See Ex. 2025 ¶ 45 (Dr. Wicker: “[T]he two abstraction modules work together to create a ‘collaboration media abstraction layer 130.’”) (citing Ex. 1114 ¶ 22; Ex. 2027, 39:6–40:12, 44:10–19 (Mr. Lett reading from and agreeing with paragraph 45 of Dr. Wicker’s Declaration)).” slip op. at 25
