“B. Level of Ordinary Skill in the Art The level of skill in the art is “a prism or lens” through which we view the prior art and the claimed invention. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). “This reference point prevents . . . factfinders from using their own insight or, worse yet, hindsight, to gauge obviousness.” Id.” slip op. at 17

“processor” to the spare processor, we determine that the claim is describing this transfer of identification of “boot processor,” which is required when transferring a boot processor’s functions to a spare because of the “problems [that] arise in attempting to idle (or eject) the boot processor.” Id. at 6:25– 27. This is confirmed by the language of limitation [1d], stating that the switching of the role of boot processor involves “changing a system identifier of the spare processor to that of the boot processor.” Thus, the firmware and operating system exchange this information identifying the boot processor, which is described in the specification as a device tree. See, e.g., id. at 13:21–35. The ’302 patent makes clear that accurate identification of which processor is the boot processor remains critical during runtime. See, e.g., id. at 6:25–27. Thus, Patent Owner is correct in requiring the system to have a way to identify the boot processor and to transfer this identification during runtime. However, as made clear in the embodiments described in the ’302 patent discussed above, this identification is for runtime purposes to accommodate runtime problems, not for booting purposes. Although Patent Owner may be correct that a function of the boot processor is to boot the system (PO Sur-reply 5), the problem identified in the ’302 patent is a problem relating to the runtime reassignment of the boot processor identity, to address a runtime need to identify the boot processor. See, e.g., Ex. 1001, 11:6–9. Accordingly, based on our analysis of the claims and specification, we determine that “switching the role of boot processor to a spare processor without shutting down the system’s operating system” means causing the system to identify the spare processor as the boot processor (e.g., in a device tree), which then causes the spare processor to appear as the boot processor to the system during runtime. Ex. 1001, 6:25–41, 11:4–18 (describing why boot processors are treated differently even after the boot process has completed); compare id. at 9:65–11:3 (process for recovering from loss of lockstep of a non-boot processor without using a spare), with id. at 11:4–43 (process for recovering from loss of lockstep of a boot processor using a spare because boot processors, during runtime, need special treatment); see also 14:66–15:21 (emphasizing that spares are only needed for recovering boot processors). We construe switching a “role of boot processor” to mean transferring an identification in the system of which processor is the boot processor. This construction comports with the embodiments described in the specification. We do not adopt an additional requirement that this procedure also requires designating which processor will boot the system in the next reboot, which is not disclosed in the specification.” slip op. at 24

“may swap processors that are failing, and perform the necessary bookkeeping to keep the operating system informed as to how to address the processors available, nothing in the Petition persuasively explains whether this generic processor swapping switches the boot processor role. As we explained in our claim construction section, the term “boot processor” is not merely a label of convenience to describe the processor that happened to have earlier booted the system. The role of boot processor is specifically switched to the spare; it is a piece of information tracked by the system. As we explain below, Petitioner does not adequately address the transfer of this information to make the system aware of which processor has the boot processor role. Petitioner asserts that “the BSP flag” of the IA-32 system is used to “determine whether a processor is the boot processor.” Pet. 17–18. Petitioner here is relying on a register used in IA-32 processors to identify whether or not they are the boot processor. This register is used during booting so that only the boot processor boots the system. See, e.g., Ex. 1008, 238–40, 710. This register does not appear to serve any further role, and Petitioner offers no persuasive evidence or argument that the processor register flag is exposed or copied to the operating system or APIC table. Petitioner’s proposed combination does not involve updating this register, nor does Petitioner explain how, even if the register were updated, it would meet the “switching” a “role of boot processor” in limitation [1d].” slip op. at 32

“information” should be given its plain and ordinary meaning as “data,” and that Patent Owner’s narrower construction of “first information” and “second information” lacks sufficient support in the intrinsic record. We agree with Petitioner that the ’802 patent Specification defines “information” as data when it uses the phrase “information (i.e., data).” See Ex. 1001, 5:60–62 (“Information (i.e., data) to be transmitted may be received in a baseband digital system 250, such as a wireless digital baseband processor.” (emphasis added)), 11:30–32 (“In this example, the signals 911 and 912 carry the same information (data).” (emphasis added)).

“argument based on Fernandez alone, we find that Petitioner has not provided a sufficient evidentiary basis to support a motivation to remove the amplification from each of Fernandez’s signal generators 10A-10E and add a single power amplifier instead. See Pet. 76–77 Ex. 1003 ¶ 235. Petitioner’s only rationale for this modification to Fernandez is that “[a] single amplifier has several advantages compared to multiple amplifiers, including lower complexity, a single (vs. multiple) potential point of failure, and lower cost,” and that one of ordinary skill “would have found a single amplifier to be a simple matter of design preference.” Pet. 76–77. Dr. Almeroth simply repeats these cursory allegations without providing any further explanation or evidentiary support. Ex. 1003 ¶ 235.

For example, Dr. Cooklev testifies that a single amplifier would need to have a wider bandwidth than the multiple amplifiers used in Fernandez, which could cause potential stability issues.

“We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35

“We agree with Petitioner that the above-quoted paragraph of Wouters teaches “combining . . . correct working codes from the scanned remote control code-sets into a new custom configuration code set” using Wouters’s “fixer,” which combines the codes into a custom codeset, gives it a name, such as “user1,” and stores it in a memory (the “RC code set data base”). See Pet. Reply 2; Ex. 1009, 10:18–20. This custom codeset includes a combination of the working codes previously tested and installed by the user. Ex. 1009, 10:18–20. We also find that the above-quoted paragraph of Wouters teaches “installing . . . the combined correct working codes of the new custom configuration code set for use by the remote control.” Specifically, Wouters teaches that, when the remote control’s batteries die, “the user may easily reinstall the chosen code set by choosing ‘user1’ from the proposed list or immediately selecting ‘user1.’” Ex. 1009, 10:20–22 (emphasis added). This reinstallation is of the combined correct working codes of a new custom configuration codeset previously stored and named by the fixer, such as the “user1” codeset. Id. at 10:20–24. We find that Wouters’s “reinstallation” of the chosen code set (e.g., the “user1” codeset) is an “installation” of that codeset.

“Petitioner does not explain why an ordinarily skilled artisan who used Ciais-Quadband’s antenna for Dou’s two antennas 206 and 208 would have departed from the commonly accepted rule of thumb and Dou’s preference for at least a quarter-wavelength spacing between antennas at the lowest frequency to the extent needed to implement the proposed combination, i.e., with only about 55% of the preferred spacing between antennas. See Pet. 60–69; Ex. 1007 ¶¶ 172–187. Hence, based on the current record, Petitioner does not establish sufficiently for purposes of institution that an ordinarily skilled artisan would have been motivated to combine Ciais-Quadband’s teachings with Dou’s teachings in the way Petitioner proposes.

“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.

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

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.

“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 does not provide a new theory of unpatentability; rather, Petitioner responds and elaborates on the theory presented in the Petition to explain why Patent Owner’s arguments are incorrect. E.g., Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d 919, 925 (Fed. Cir. 2019) (“Parties are not barred from elaborating on their arguments on issues previously raised.”); Belden Inc. v.

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 also disagree with Petitioner that “Dr. Abidi provided well- reasoned analysis that Behbahani teaches determining and comparing desired and interferer signal strengths.” Reply 27 (citing Ex. 1003 ¶¶ 179– 181). 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.
