“Based on Petitioner’s arguments and evidence, we are persuaded that Petitioner has shown sufficiently for purposes of this Decision that Zhang teaches the recited “digitizing” step of element 1C. For example, Zhang teaches that its ADC 220 “converts the down-converted multi-channel analog RF signal to a multi-channel digital RF signal.” Ex. 1013 ¶ 27 (cited by Pet. 22). Zhang explains that “many modifications, variations, alternatives, and equivalents . . . are intended to be within the scope of [its] invention,” and gives the example that “the RF channels need not be contiguous.” Id. ¶ 48 (cited by Pet. 22). We agree with Petitioner that Zhang’s example teaches or suggests that the RF channels may be contiguous. Zhang further describes “demultiplex[ing] the multi-channel digital RF signal into separate digital RF channels C1 to Cn,” which “contain content channels that are selected or used by a subscriber.” Id. ¶ 28 (cited by Pet. 22).

Patent Owner does not address the level of ordinary skill in the art in its Preliminary Response. Based on our review of the record before us, we determine that Petitioner’s stated level of ordinary skill in the art is reasonable because it appears consistent with the evidence of record, including the asserted prior art. Accordingly, we adopt Petitioner’s definition for the purposes of this Decision.” slip op. at 8

“On the present record, we do not discern a need to construe explicitly any claim language because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).” slip op. at 9

“persuaded on the current record that Patent Owner provides sufficient evidence to establish the failure of others. Patent Owner makes much of Broadcom and CableLabs allegedly failing to “realize the possibility of remote spectrum monitoring” prior to the ’008 patent. See Prelim. Resp. 50–52. The mere failure to “realize the possibility” of a certain technique or device, however, is not sufficient to show the failure of others. Rather, the failure of others as an indicium of nonobviousness generally 8 DOCSIS refers to “Data Over Cable System Interface Specification.” Ex. 1011, 1:42–43. relates to situations where others failed while attempting to address a particular problem. See In re Cyclobenzaprine Hydrochloride Extended- Release Capsule Pat. Litig., 676 F.3d 1063, 1081 (Fed. Cir. 2012) (“Evidence that others tried but failed to develop a claimed invention may carry significant weight in an obviousness inquiry. . . . [E]vidence of failed attempts by others could be determinative on the issue of obviousness.” (emphases added)); see also Volvo Penta of the Americas, LLC v. Brunswick Corp., 81 F.4th 1202, 1213 (Fed. Cir. 2023) (“Indeed, we have found that ‘[o]bjective considerations such as failure by others to solve the problem . . . may often be the most probative and cogent evidence of nonobviousness.’” (emphasis added)). In this case, Patent Owner does not show sufficiently that any alleged failure experienced by Broadcom or CableLabs (or any other party) occurred attempting to address a pertinent problem.” slip op. at 15
