“A reference is considered analogous prior art: (1) if the reference is from the same field of endeavor as the claimed subject matter, or (2) if “the reference still is reasonably pertinent to the particular problem with which the inventor is involved,” even though the reference is not within the field of the inventor’s endeavor. In re Bigio, 381 F.3d at 1325. The field of endeavor test asks if the structure and function of the prior art is such that it would be considered by a person of ordinary skill in the art because of the similarity to the structure and function of the claimed invention. Bigio, 381 F.3d at 1325–27. A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor’s endeavor, it is one which, because of the matter with which it deals, logically would have commended itself to an inventor’s attention in considering his problem.

“Petitioner proposes constructions for three claim terms, including the term “trick play functionality.” Pet. 22–23. Patent Owner argues for construction of the related claim term “the first and second indexes enabling trick play functionality.” See PO Resp. 41–49. We determine that it is not necessary to provide an express interpretation of any of those claim terms because construction of the proposed terms does not impact our determination that Petitioner has not shown that one of the prior art references is analogous to the claimed invention. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

“Under the particular circumstances in this case, we need not assess the merits of Patent Owner’s Motion to Exclude. As discussed above, we have determined that Petitioner has not demonstrated by a preponderance that Kaku is analogous prior art to the ’792 patent and do not reach Petitioner’s arguments on the motivation to combine Kaku with Zetts or Seo. Accordingly, Patent Owner’s Motion to Exclude is dismissed as moot.” slip op. at 34

“As discussed above (supra § III.E.4.a), Petitioner’s papers fail to link Dr. Reader’s declaration testimony on the level of ordinary skill in the art to the analogous art inquiry and fail to identify a field of endeavor for the ’792 patent. We therefore agree with Patent Owner that Petitioner’s demonstrative slide 53 presents improper new arguments that have not been previously made. See Paper 38, 2 (“The parties may only rely upon evidence that has been previously submitted in the proceeding and may only present arguments that have been previously made in the submitted papers. No new evidence or arguments may be presented at the hearing.”), 5 (“Demonstratives are not a mechanism for making new arguments.”). We therefore sustain Patent Owner’s objections. We note, however, that demonstratives are not evidence. See id. at 5 (“Demonstrative exhibits used at the hearing are not evidence, nor will they be relied upon as evidence. Rather, demonstratives are visual aids to a party’s oral presentation regarding arguments and evidence previously presented and discussed in the papers”); CTPG 84 (“Demonstrative exhibits used at the final hearing are aids to oral argument and not evidence.”). In this Final Written Decision, we rely solely on the arguments properly presented in the parties’ briefs and the evidence of record, not on the demonstratives.” slip op. at 35

“ordinary meaning of “bias signal” is “a signal having a steady predetermined level.” Resp. 28; Reply 6–7. The parties also agree that at least some information signals may be considered “bias signals.” The crux of the parties’ disagreement is which type of information signal. The ’940 patent defines “information signal” as “[t]he signal that contains the information that is to be transmitted. As used herein, it refers to the original baseband signal at the source.” Ex. 1001, 8:48–50 (emphasis added). Thus, the ’940 patent clearly defines “information signal” as “the original baseband signal at the source.” The ’940 patent defines “baseband signal” as: Any generic information signal desired for transmission and/or reception. As used herein, it refers to both the information signal that is generated at a source prior to any transmission (also referred to as the modulating baseband signal), and to the signal that is to be used by the recipient after transmission (also referred to as the demodulated baseband signal). Ex. 1001, 7:41–47. The ’940 patent clearly gives a broad meaning to “baseband signal” such that it encompasses any signal desired for transmission and/or reception, but the definition of “information signal,” as quoted above, does not refer to any baseband signal. Rather, it refers to “the original baseband signal at the source.” Ex. 1001, 8:48–54. By including the terms “original” and “at the source,” the meaning of information signal, as defined by the ’940 patent, is more limited than the definition of a baseband signal. Thus, Petitioner’s contention that the meaning of “information signal,” and, hence, “bias signal” should be expanded to include any “baseband signal” (Reply 4) improperly takes “information signal” out of context. Petitioner’s contention eliminates the terms “original” and “at the source” from the ’940 patent’s definition of “information signal,” without providing any reason why those terms should not be considered. Accordingly, we agree with Patent Owner and construe “bias signal” to mean “(1) a signal having a steady, predetermined level or (2) the original baseband signal at the source.”” slip op. at 11

“Further, Patent Owner explains that “[t]he parties agree on the portion of the ‘to gate’ construction that is material to this IPR, i.e., that ‘to gate,’ the switch module must change between connecting and disconnecting the bias signal from the switch module’s output.” Id. at 37 (citing Pet. 13–14). Patent Owner’s proposed construction is consistent with the construction proposed by Petitioner. See Dec. 11 (discussing Petitioner’s construction of “to gate [a signal]” as “to change . . . between (i) connecting a signal at an input to an output such that the input and output have an equal voltage, and (ii) disconnecting the signal from the output” (quoting Pet. 14)). In light of the consistency between the proposed constructions, and in light of the lack of an actual controversy between the parties with respect to the impact of the minor differences in the proposed meanings of this term, we need not construe expressly the term further.4 Petitioner’s Reply does not challenge Patent Owner’s arguments regarding these claim terms. Accordingly, we adopt the construction of “switch module,” as reproduced above, for the reasons explained in our Decision to Institute. See Dec. 8–11. Additionally, we decline to construe expressly the terms “summer” and “to gate,” for the reasons discussed above.” slip op. at 13

“3. Level of Ordinary Skill in the Art Petitioner contends that one of ordinary skill in the art as of October 1998 would possess, at a minimum, either (a) a master of science degree in electrical engineering and two or more years of experience in radio frequency circuit design, or (b) a bachelor of science degree in electrical engineering with three or more years of experience with the design and development of RF circuits. Pet. 11 (citing Ex. 1002 ¶¶ 24–29). Petitioner’s argument is supported by Dr. Larson’s testimony. Ex. 1002 ¶¶ 24–29.

“High Level Radio Frequency (“RF”) Source 10. The RF signal contains the information that television watchers see and hear.” Pet. 29 (citing Ex. 1023, 1:14–17). Petitioner asserts that Dobrovolny’s “RF Source signals are information signals that constitute ‘bias signals’ as that term is defined by the ‘940 patent.” Id. (citing Ex. 1002 ¶¶ 154, 210). Petitioner’s position is based on its claim construction of “bias signals” as “encompassing information signals.” Id. Notably, in the Petition,5 Petitioner does not assert that the recited “bias signal[s]” would have been obvious to one of ordinary skill in the art in light of Dobrovolny’s RF Source signals; rather, Petitioner’s position is that “bias signal[s]” are disclosed expressly. See id. (“RF Source signals . . . constitute ‘bias signals’”) (emphasis added).6 Patent Owner’s primary argument is as follows: [E]ven accepting [Petitioner’s] assertion that the ’940 patent expanded the ordinary meaning of ‘bias signal’ to include ‘information signal’ as defined in the patent . . . . [Petitioner] does not even allege, much less prove, that the purported ‘bias signal’—Dobrovolny’s high frequency Radio Frequency (RF) television signal—meets either of these definitions. Resp. 38–39. Patent Owner reiterates that Petitioner’s “only attempt to prove that the Dobrovolny RF television signal satisfies the claimed first and second bias signals is its assertion that Dobrovolny’s ‘RF signal contains the information that television watchers see and hear.’” Id. at 39 (quoting 5 As discussed infra, see Section III.C., Petitioner’s additional argument that bias signals would have been obvious in light of Dobrovolny’s RF Source signals constitutes a new argument, set forth only in Petitioner’s Reply, and we do not consider it here for the reasons explained below. 6 With respect to independent claim 18, Petitioner relies upon its arguments directed to the similar claim limitations of claim 1. See Pet. 44–45 (referring to Petitioner’s arguments directed to claim 1). Pet. 29). Patent Owner contends, however, that “an ‘information signal’ is not just any signal containing information . . . as [Petitioner’s] argument implicitly presumes. Rather, as defined in the ’940 patent, an information signal is restricted to ‘the original baseband signal at the source.’” Id. (quoting Ex. 1001, 8:48–54). Petitioner’s argument in its Reply is based on its incorrect claim construction of “bias signal” as encompassing any information signal. See, e.g., Reply 7 (asserting that the “bias signal” is met by Dobrovolny’s disclosure because it teaches “an information carrying High Level RF Source for reception”) (citing Ex. 1023, 1:14–17; Ex. 1002 ¶¶ 154, 210). As explained above, “bias signal” is understood to mean “(1) a signal having a steady, predetermined level or (2) the original baseband signal at the source.” See supra Section II.A. Petitioner does not argue, and has not established, that Dobrovolny’s RF Source signal is either at a steady, predetermined level or is the original baseband signal at the source. Thus, Petitioner has not shown that Dobrovolny discloses the “bias signal” limitations recited in claims 1 and 18, and the claims that depend from each.7 Accordingly, Petitioner has not shown, by a preponderance of the” slip op. at 19

“Read in light of the Specification, “providing said communication resource to queued packet data users on a tier-by-tier basis,” as recited in claim 1, means providing the communication resource to queued users of packet data on a tier-by-tier basis. We are persuaded by Patent Owner that this is the only reasonable reading that is consistent with the Specification. Petitioner provides no examples in the Specification consistent with its reading. Although the preamble of claim 1 recites a “method of processing queued data packets,” this is consistent with the Specification’s general statement that the invention pertains to “an improved packet data queueing algorithm,” Ex. 1001, 9:3. We do not read this general statement in the preamble of claim 1 (or the similar preamble recitations in claims 11 and 24) to provide a basis for construing more specific language in the body of the claim in a manner inconsistent with the description in the Specification. In sum, the only reasonable reading of “queued packet data users,” in the context of the dependent claims, and in light of consistent description in the Specification, is queued users of packet data, not users of queued packet data.” slip op. at 14
