      “The second and third asserted benefits—reduced complexity and reduced latency—rest on the declaration of Dr. Kotzin (Ex. 1003 ¶ 64) rather than on any disclosure of Andersson or Khan. We accord that testimony little weight on this point because it asserts the benefits in conclusory terms without explaining why they would result from inserting a scheduling grant into Andersson’s undefined “other bits,” as distinct from Khan’s separate-slot design.” slip op. at 20

      “A.

As explained above, the current record does not support limiting the term “payout” to just the amount a player will win in relation to the amount wagered.

Pet. 35–36 (“had the first selected position not been randomly selected, the player would only be eligible for the basic payout”). Further, Kido even describes its bonus routines and jackpots as payouts.

As explained above, the current record does not support limiting the term “payout” to just the amount a player will win in relation to the amount wagered.

Patent Owner next contends that Kido does not disclose a first payout that is “for the spin of the roulette wheel.” Prelim. Resp. 29. Patent Owner’s argument is premised on the cumulative nature of Kido’s Prog bonus – it builds with every spin of the roulette wheel until won. Id. (“Each time the wheel is spun, 0.5% of the amount wagered is added to the progressive jackpot, and thus, the jackpot’s value reflects multiple spins of the roulette wheel.”). Thus, according to Patent Owner, the value of the jackpot is determined using multiple spins of the roulette wheel and is not “for a spin of the roulette wheel” as claimed.” Id. at 30. The claims, however, only require a first payout that is higher than a second payout. Nothing prohibits the higher payout from accumulating from prior spins of the roulette wheel because, when it is actually won, it will be for that last spin of the roulette wheel. Ex. 1005, 8:35–36 (“indicating that the first player is to be paid at the first payout for the spin of the roulette wheel”). Regardless of how Kido’s Prog bonus accumulated, it is paid for a spin of the roulette wheel – at that juncture Kido discloses each claim element. Anticipation occurs when a prior art reference discloses every element of a patent claim at a point in time, as Kido does with a single spin of the roulette wheel that pays the Prog bonus. As persuasively explained by Petitioner, “the steps of Figure 12 (including A13) occur within a single round of roulette, for a single spin of the roulette wheel, until the routine ‘returns to the step of A1 and is transited to a next game.’” Pet. 39 (quoting Ex. 1007 ¶ 233).” slip op. at 13

      “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.

      “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

Pet. 10; Ex. 2015; Ex. 2025, 31–47. Instead, the district court adopted a “plain-and-ordinary meaning” construction, which Patent Owner proposed. PO Resp. 36–38; PO Sur-reply 10 n.2; Ex. 2015; Ex. 2025, 31–47. In the Petition, Petitioner proposed applying the plain and ordinary meaning construction that had already been preliminarily adopted by the district court. Compare Pet. (filed May 1, 2024) with Ex. 2015 (preliminarily adopting plain and ordinary meaning construction on March 25, 2024). Applying Revvo, we find that Petitioner had a sufficient reason for advancing the broader, court-adopted construction in this IPR. Thus, we give the dynamic limitation its plain-and-ordinary meaning, which is “adjusting during operation based—at least in part—on information gained during operation.”” slip op. at 14

      “Variable Bandpass Filter Block does not teach the recited “component” or “impedance” that is dynamically adjusted, 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 a variable impedance of a circuit or component thereof, while it is in the signal path.” 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” or “component.” 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 component,” “a circuit,” or “an impedance” in the claims.” Sur-reply 4 (citing Ex. 2020 ¶¶ 46–48, 71, 74–83). Dr. Larson testifies that the ’330 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.” Id. There is no dispute that the recited “circuit” or “component” in the receiver signal path is referring to these “function blocks.” See Tr. 22:20–23:4. The ’330 patent states that Figure 8A, which includes function block 820, is “an embodiment of the present invention” that describes a “possible power saving technique[].” Ex. 1001, 3:30–33, 8:20–25. Similarly, Figure 9A, which includes function block 920, “illustrate[s] one of the possible power saving techniques.” Id. at 3:33–34. The ’330 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.” Ex. 1001, 8:22–25 (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,” “component,” or “impedance.”” slip op. at 42

      “The absence of meaningful disclosure of the implementation details of the circuit in the ’330 patent suggests that the circuit implementation details Patent Owner argues about now would have been within the understanding of a person of ordinary skill in the art. That is, Patent Owner did not provide in its own specification “the type of detail [it] now argues is necessary in prior art references,” which permits a “finding that one skilled in the art would have known how to implement the features of the references and would have concluded that the reference disclosures would have been enabling.” In re Epstein, 32 F.3d 1559, 1568 (Fed. Cir. 1994). When a patent specification does not “specifically describe[]” any “equipment or techniques to be used,” it may be deduced “that all of the equipment and technical knowledge required to perform the claimed method” is known to one of ordinary skill in the art. In re Fox, 471 F.2d 1405, 1407 (CCPA 1973); see also Southwire Co. v. Cerro Wire LLC, 870 F.3d 1306, 1312 (Fed. Cir. 2017) (without proof to the contrary, when there is no focus on a disputed claim limitation in the specification, the limitation is merely “an observed result of an old process”). To that end, Petitioner provides persuasive testimony from Dr. Abidi that signal strength measurement circuits were known in the art, and that a person of ordinary skill in the art would have understood how to implement a known technique for measuring signal strength, which is not disputed by Patent Owner. Ex. 1003 ¶¶ 180– 181; Ex. 1042 ¶¶ 12–16; see Pet. Reply 24–26; Pet. 60–62. Accordingly, we agree with Petitioner that Behbahani’s disclosure at least suggests circuitry for performing such a determination of signal strength. See Pet. Reply 24 (citing Pet. 60–61; Ex. 1003 ¶¶ 92–98, 179–181). Petitioner further argues that Tan “provides an example of circuitry used to detect signals at various points in the low-pass filter signal path as a means of implementing a prefilter automatic gain control.” Pet. 60–61 (citing Ex. 1006, 481); Ex. 1003 ¶ 180. The example in Tan is a peak detector circuit. Pet. 61; Ex. 1003 ¶ 180; Ex. 1006, Fig. 8. Dr. Abidi testifies that a person of ordinary skill in the art would have been motivated to use Tan’s signal strength measurement circuitry to measure nodes AI and AO. Ex. 1003 ¶ 180. In response to Patent Owner’s argument that Petitioner does not sufficiently explain how to use Tan’s peak detector in Behbahani (PO Resp. 70), Dr. Abidi provides testimony explaining how Tan’s peak detector circuit provides a measure of the signal strength, which we find persuasive, and is unrebutted by Patent Owner.

      “Thus, the parties do not dispute the meaning of “signal path,” and we adopt the district court’s construction of plain and ordinary meaning, as agreed by the parties. See PO Resp. 40–41; Pet. 9; Ex. 2025, 14. The dispute concerns the application of this and the surrounding claim language (i.e., “in the receiver signal path”) to the disclosures in Behbahani. See PO Resp. 40–42. 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 in limitation 1(e) and the corresponding limitations in independent claims 3, 5, 7, and 8 – i.e., that “[t]he plain language requires adjusting a bias current, or a bias current and an impedance, in a circuit, while it is in the signal path.” See PO Resp. 48.

      “Owner’s] settled expectations in long-standing patent rights, and Office policies and efficiency.” Id.; see id. at 25–26. Patent Owner’s arguments essentially reassert the arguments made in the Preliminary Response that inter partes review should be discretionarily denied under 35 U.S.C. § 314(a) and 35 U.S.C. § 325(d). In the Institution Decision, we were not persuaded by these arguments. Inst. Dec. 15–22. Patent Owner argues that in Ecto World, LLC v. RAI Strategic Holdings, Inc., IPR2024-01280, Paper 13 (PTAB May 19, 2025) (§ A precedential) supports denial under 35 U.S.C. § 325(d). Sur-reply 25. 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. Piranha Media Distribution, LLC, IPR2024- 01252, Paper 17, at 3 (PTAB April 17, 2025). Id. However, in Hulu, the patent owner timely sought Director Review after the institution decision, and upon Director Review, the institution decision was vacated and denied. IPR2024-01252, Papers 16, 19, 27. By contrast, here, Patent Owner raised this issue for the first time in the Sur-reply (filed August 5, 2025, nearly three months after Ecto World was designated precedential), approximately three weeks prior to oral argument. Patent Owner also did not file a motion to terminate the proceeding. Although we recognize that “that the Board has the inherent authority to reconsider institution decisions (beyond the regulatory time for a patentee’s entitlement to seek reconsideration),” Sling TV, L.L.C. v. Realtime Adaptive Streaming LLC, 840 F. App’x 598, 598–99 (Fed. Cir. 2021), we decline to do so at this late stage in the proceeding.” slip op. at 63

    Claims 1, 2, and 4–23 were not shown unpatentable over Behbahani, Leete, and Tan because the combination did not teach comparing desired and interferer signal strengths.

    RulingsFinal written decision
    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “Behbahani teaches “comparing the strength of the desired signal to the strength of the interfere signal,” as recited in limitation 1(a). See PO Resp. 68–69; Sur-reply 21–23. Although Petitioner argues that Behbahani “expressly teaches comparing the desired and interferer signal strengths,” Petitioner does not cite to sufficient evidence in support of this statement. Pet. 38. The basis of Petitioner’s argument is that Behbahani teaches the same process for determining signal strengths as shown in Figure 4 of the ’202 patent. Figure 4 of the ’202 patent is reproduced below: Figure 4 shows, among other things, signal strength indicator circuits 440 and 450 connected to input line 410 and output line 460, on either side of gain element 420 and filter 430. Ex. 1001, 6:53–57. The input signal on input line 410 is shown as desired signal 412 and interferers 464 and 466. Id. at 59–61. Figure 4 is further described as follows. The signal strength indicators 440 and 450 do not provide information as to the relative sizes of the desired and interfering signals. Rather, a cumulative signal level is provided at their outputs. For example, the first signal strength indicator 440 outputs a level corresponding to the sum of desired signal 412 and interfering signals 414 and 416, while the second signal strength indicator 450 provides a signal level corresponding to the sum of desired signal 462 and interfering signals 464 and 466. In this specific example, the gain of the gain and filter circuit combinations is shown as approximately one, while the interfering signals 414 and 416 signal levels are reduced. A comparison of the signal levels provided by the signal strength indicators 440 and 450 indicates that much of the combined received signal on line 410 has been filtered. Accordingly, it may be deduced that large interfering signals present at the input are being filtered by the filter 430. From this information, as will be shown in greater detail below, the bias, impedance, and gain of the gain stage 420 and filter 430 combination may be optimized to reduce power dissipation. Ex. 1001, 6:61–7:13 (emphasis added). In other words, Figure 4 shows a comparison of a sum of the desired and interferer signals output from the strength indicator circuits, not a comparison of the strength of the desired signal and the strength of the interferer signal, as required by the claim language. See Sur-reply 22–23. The ’202 patent describes Figure 4 as “an embodiment,” and claims are not limited to specific embodiments described in the specification. See Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005) (en banc). Petitioner even admits that Figure 4 “compar[es] a cumulative signal strength at a first node to a cumulative signal strength at a second node.” Pet. 36 (emphasis added).

Ltd. P’ship v. Biomarin Pharm. Inc., 825 F.3d 1360, 1366 (Fed. Cir. 2016). We also note that our Consolidated Trial Practice Guide (“CTPG”) states that In most cases, the Board is capable of identifying new issues or belatedly presented evidence when weighing the evidence at the close of trial, and disregarding any new issues or belatedly presented evidence that exceeds the proper scope of reply or sur-reply. As such, striking the entirety or a portion of a party's brief is an exceptional remedy that the Board expects will be granted rarely. CTPG at 80, 84 Fed. Reg. 64,280 (Nov. 21, 2019). We follow that guidance here. Further, Patent Owner argues that Dr. Abidi’s testimony as a co- author of Behbahani is “self-serving and unsupported.” Mot. 6–7. The fact that Dr. Abidi is a co-author of Behbahani, as well as Petitioner’s expert, is not, in and of itself, sufficient to discredit Dr. Abidi’s testimony. The CTPG provides that “[t]he Board has broad discretion to assign weight to be accorded expert testimony.” CTPG 35. We are capable of discerning from the testimony and the evidence presented whether Dr. Abidi’s testimony should be entitled to any weight, either as a whole or with regard to specific issues. We will weigh the testimony on an issue-by-issue basis as appropriate. Moreover, to the extent that Patent Owner has pointed out the inadequacies of Dr. Abidi’s testimony, we are also capable of noting those inadequacies and weighing that testimony accordingly. For the foregoing reasons, Patent Owner’s motion to strike is denied.” slip op. at 11

We have reviewed the Dr. Abidi’s testimony cited in the Petition and Reply for limitation 1(a) (Ex. 1003 ¶¶ 95, 96, 113–120, 179–181; Ex. 1042 ¶¶ 12–16), and we disagree that Dr. Abidi provided well-reasoned analysis that Behbahani teaches comparing desired signal strengths with interferer signal strengths. Rather, Dr. Abidi’s testimony focuses on determining or measuring desired and interferer signal strengths, generally simply repeats what is in the Petition, and only provides a conclusory assertion that Behbahani expressly teaches comparing the strengths of the desired and interferer signals without providing any explanation. See TQ Delta, LLC v. Cisco Sys., Inc., 942 F.3d 1352, 1358–59 (Fed. Cir. 2019) (“Conclusory expert testimony does not qualify as substantial evidence.”). Accordingly, Dr. Abidi’s supporting testimony is also deficient. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). As Patent Owner points out, the only comparison mentioned by Petitioner in Behbahani is to derive the strength of the interferer signal.
