“See Section II.C.3.a.ii supra. Although Dr. Rubin calls Hayhurst’s security benefits “ancillary” (Ex. 2033 ¶¶ 108–109, quoted in PO Resp. 40), this does not align with Hayhurst (see Ex. 1007 ¶¶ 2, 7, 8, 21). For example, Hayhurst describes the security measures in the Technical Field section (id. ¶ 2) and the Summary of the Invention section (id. ¶¶ 7, 8). Hayhurst also discusses piracy deterrence in both the Summary of the Invention section (id. ¶ 8) and the invention’s detailed description (id. ¶ 21). Because Dr. Rubin does not give sufficient weight to Hayhurst’s discussion of piracy deterrence and security, we do not credit Dr. Rubin’s testimony on this issue. See Ex. 2033 ¶¶ 108–109.

“We are persuaded and find for the reasons given that Petitioner fails to prove by a preponderance of the evidence that White teaches or suggests “receiving a bus workload for a communication bus and a first processing element workload for a first processing element based on an integrated circuit reaching a limit.” Patent Owner’s expert Dr. Brogioli testifies that “[t]he workload is a function of the demands imposed by, e.g., applications running on the system, and may or may not be subject to direct control, whereas the conditions under which that workload is processed are controlled directly.” Brogioli Decl. ¶ 66. We agree with Dr. Brogioli and find that White’s frequency and voltage monitoring and adjustments do not result in the power management logic receiving the bus workload as recited in claim element 4[a]. Id. ¶¶ 64–66. We find the testimony of Mr. Wyatt on this issue unconvincing. Wyatt Decl. ¶ 103. In support of his opinion that “monitoring the operating voltages and frequencies of the logic core 120A and common logic bridge 110 is monitoring the workload of those components,” he states: “It was well understood that operating frequency and voltage of a component reflect the activity and use, or workload, of that component.” Id. However, he does not provide any evidentiary support for this statement. We, therefore, give it little weight.

“Nowhere does Petitioner or its expert point to an explicit disclosure in Bose of making a comparison of the claimed “bus workload and a bus workload threshold.” Instead, Petitioner relies on its expert’s opinion as to what a person of ordinary skill might have known, without any additional supporting evidence. See, e.g., Pet. 26 (“[A person of ordinary skill] would have understood global PMCU compares a workload threshold as exemplified by the predicted power and performance of each power mode and the monitored workload to select and adjust the power mode of a component” (citing Wyatt Decl. ¶¶ 54–55)). This opinion is not supported by the record. The only disclosure of a comparison in Bose that we have been shown is the comparison of PowerTotal to PowerMax in step 303 of Figure 3, which Petitioner does not rely on to meet the “comparison” limitation in the claim. Hearing Tr. 17:16–20. Also without proper support is Petitioner’s assertion that “a [person of ordinary skill] would have understood that in Bose, selecting or adjusting power mode for a component entails comparing a workload threshold, such as predicted power and performance associated with each power mode with real time statistics, such as the monitored workload of a component.” Pet. 26 (citing Wyatt Decl. ¶¶ 55–56). We determine that for the reasons given, Petitioner fails to demonstrate by a preponderance of the evidence that the claimed comparison element 1[g] of claim 1 is taught or suggested by Bose.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted
“Based on our review and consideration of the current record, we determine that Petitioner has sufficiently shown that the combination of Bigbee and Nguyen teaches the recited elements of limitation 19a for purposes of institution and has provided reasons sufficiently supported by factual underpinnings to combine the references with a reasonable expectation of success. Nguyen discloses, “[t]he present invention addresses mechanisms for combining recoverable and non-recoverable error handling mechanisms efficiently in FRC-enabled processors.” Ex. 1006 ¶ 9. Subsequently, Nguyen distinguishes recoverable from non-recoverable errors by treating non-recoverable errors differently from recoverable errors. Nguyen discloses, “If an error reaches error detector 140 from either core 120, recovery module 150 is activated to implement a recovery routine. Recovery can be implemented with relatively low latency by hardware, software, firmware or some combination of these.” Id. ¶ 22, Fig. 1. “However, an FRC error will be triggered if the corrupted data from one execution core and an uncorrupted version of the data from the other execution are allowed to reach FRC checker 130 before recovery module 150 is activated.” Id. Nguyen recognizes, “[s]ince FRC errors are not recoverable, reset module 160 resets the system, if FRC checker 130 signals an FRC error before the underlying parity/ECC error is detected.” Id. Nguyen further recognizes that, “[n]ot all FRC-errors are traceable to underlying parity/ECC or other correctible soft errors. For those that are, it is faster for error detector 140 to address the under lying soft error than for FRC-checker to address the FRC error that results when the corrupted data reaches FRC boundary 104.” Id. ¶ 23 (emphasis added). In this instance instead of the FRC-error being processed by the FRC checker 130 and the Reset module 160, the FRC error is directed to the Error detector 140 and eventually recovery module 150. See id. at Fig. 1. Nguyen also discloses, “the recovery routine triggered by error detector 140 provides greater system availability than the reset routine triggered by FRC checker 130” and “[e]xpanding the FRC boundary thus increases both the amount of logic that is duplicated for execution cores 120 and the flight time, during which detectable errors may be identified.” Id. ¶ 30, Fig 1; see Pet. 37. Nguyen further discloses, “[t]he former increases FRC protection, albeit through a reset mechanism” as shown in Figure 1, elements FRC Checker 130 and Reset Module 160. Ex. 1006 ¶ 30. “The latter increases the likelihood that errors identifiable through parity, ECC [error correction code] or similar core-specific protections are handled through recovery rather than reset” as shown in Figure 1, elements Error Detector, 140 and Recovery Module 150.

“system.” Under Phillips, the starting point for the analysis is the language of the claims themselves. See Phillips, 415 F.3d at 1314. The language of claim 9 does not include limitations precluding the later occurring transfer of any profile information as a result of tagging the first computer of a first visitor visiting a first website. See Ex. 1001, 14:7–40. We also agree with Petitioner’s arguments that the language of claim 9, by use of the transitional phrase “comprising,” does not preclude the occurrence of “transferring to the third party computer system any profile information” after the step of “arranging for a third party computer system . . . to electronically tag a first computer of a first visitor visiting a first website, which occurs “at a first time.” See id. We also do not agree with Patent Owner’s arguments that the ’615 Patent Specification supports its construction. Although Patent Owner directs attention to the ’615 Patent Specification disclosures that the BT computer company stores a visitor’s collected profile information and does not transfer it to the second media property, but asks the second media property to tag the visitor or arrange for a tag to be placed (see PO Resp. 10; Ex. 1001, 9:47–54), and further discloses that the BT company has no economic incentive to transfer profile information to the second media property (see PO Resp. 11; Ex. 1001, 9:54–65), these disclosures do not provide sufficient support for Patent Owner’s requirement that “arranging for a third party computer system . . . to electronically tag a first computer of a first visitor visiting a first website” must not result in transfer of visitor profile information to the third party computer system.

“We do not agree with Patent Owner that Petitioner’s showing uses the same sound data to teach the “first sound data” of limitation 1.a and the “second sound data” of limitation 1.c. Patent Owner is correct that Rosenberg’s claim 5 describes the determination of a volume threshold based on the volume of the ambient audio signal in which characteristic form(s) (e.g., the name of the user of the media player) are present. Ex. 1006, 13:66–21, 14:28–30. However, the Petition describes using Fu’s “predetermined threshold” in combination with Hart-787’s device, which attenuates audio output of a device upon detecting a user’s utterance intended to gain the attention of the device, in order to “include adjusting the audio output volume of a wirelessly-linked audio-producing device when the voice-controlled device determines that the ambient noise level at the time a Ex. 1004, 2:22–37, 5:61–6:10, 9:18–25; Ex. 1005 ¶¶ 24, 32, 54; Ex. 1003 ¶¶ 88–89). Petitioner further proposes including a threshold that is advantageously based on the environment in which the device is operating as described in Fu, for example to respond to differing levels of noise at different times of day. Id. at 26, 29–30, 40 (citing Ex. 1006, 10:42–67, 14:28–30; Ex. 1003 ¶¶ 48–53, 55, 58, 87, 91, 107–109). We agree with Petitioner that Patent Owner’s arguments address the references individually instead of addressing the combination of the teachings proposed in the Petition. See Pet. Reply 8, 13–14; see also Dec. on Inst. 21–22, 23–24, 25–26. The Petition relies upon a combination of elements of Hart-787 with the predetermined threshold as taught in Fu and with establishing such a threshold based on the operating environment of a device as in Rosenberg. Pet. 26–31, 34–41. Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition. We also find that the preponderance of the evidence supports Petitioner’s showing regarding the motivation to combine the references.” slip op. at 23

See Pet. 23 (citing Ex. 1004, 5:47–51; Ex. 1003 ¶ 82), 43–44 (citing Ex. 1004, 1:67–2:7, 2:26–27, 5:47–51; Ex. 1003 ¶ 118). In addition, Petitioner shows that these control signals were well-known in the art and would have been known to one of ordinary skill in the art at the time of the invention, supporting its showing with additional testimony from its declarant. Id. at 44 (citing Ex. 10183, 2:39–47, 5:35–38; Ex. 10194 ¶¶ 3, 13; Ex. 1003 ¶¶ 44–45, 118). We conclude Petitioner’s evidence regarding the showing in Hart-787 is sufficient with respect to this point. Hart-787 describes altering a signal sent to the speaker to attenuate the audio from that speaker. Ex. 1004, 1:67– 2:1. Petitioner’s declarant testifies that using transmitted control signals to do this would have been known to one of ordinary skill. Ex. 1003 ¶¶ 44–45, 82, 118. We consider Petitioner’s evidence regarding what one of ordinary skill in the art would have understood from Hart-787’s disclosure to be sufficient for the showing regarding the “causing one or more commands to be automatically issued to the controllable appliance to thereby cause” that appliance to transition to a lower volume level, as required in limitation 1.e.

“Figure 6 of Rauhala has been annotated by Patent Owner to show that the parallel connection (outlined in red) including resistors R1, R2. R3 and switches ka, kb is outside the signal path (highlighted in yellow) through differential amplifier 61. Prelim. Resp. 38. Petitioner identifies R1, R2, R3 and switches ka and kb as the claimed variable impedance. See, e.g., Pet. 39–41. The Petition (and the supporting Baker Declaration) do not explain adequately how, under this interpretation by Petitioner and its expert, Rauhala meets the adjusting an impedance “in the signal path” limitation. See Prelim. Resp. 39–41. For the reasons given, therefore, even if we were to disagree with Patent Owner’s construction of “impedance,” we agree with Patent Owner that Petitioner fails to demonstrate sufficiently that Rauhala meets the limitation in claims 7 and 19 requiring “dynamically adjusting one or more of an impedance . . . in the [receiver] signal path.” For the reasons given, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claims 11 and 13 as anticipated by Rauhala.

“We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process.

“For purposes of this Decision, we thus make a preliminary determination that collateral estoppel precludes Patent Owner from relitigating the issue of whether Kovatch teaches a ranking associated with web site addresses indicating the order in which to access a plurality of preselected web sites. In challenging independent claims 1 and 2 as unpatentable under 35 U.S.C. § 103(a) over Kovatch and Burrows, the Petition presents an element-by-element analysis to support its position. Pet. 14–32. That analysis relies on Kovatch’s disclosure of the HeyAnita system for accessing web sites to retrieve information a user requested, and relies on Burrows for disclosure of a system for ranking database records that are “presented to the users in a rank order where the pages having a higher rank are presented first.” Id. at 12–13 (citing Ex. 1006, 27:28–32, 32:14–47). Petitioner reasons that a person of ordinary skill in the art “would have found it obvious to apply Burrows’s numbered ranking and polling approach to Kovatch’s destination tree to better identify and present the records of the most interest to the user.” Id. at 13 (citing Ex. 1006, 3:56– 58). In particular, because Burrows explains that “there needs to be a way to rank order the list in a meaningful manner,” Petitioner reasons that a person of ordinary skill in the art “would have been motivated to apply Burrows’s numbered ranking to Kovatch’s destination tree web pages to provide those of interest first.” Id.

Although Patent Owner makes a number of arguments in its Preliminary Response why the combination does not meet certain limitations, those arguments are precluded by our preliminary determination that collateral estoppel applies. See Prelim. Resp. 29–44.7 We have thus re-evaluated the parties’ arguments in light of the findings made in the 846 IPR, and affirmed by the Federal Circuit, and we conclude that Petitioner demonstrates a reasonable likelihood of prevailing on its challenge of independent claims 1 and 2 as unpatentable under 35 U.S.C. § 103(a) over Kovatch and Burrows.

“The party seeking to invoke collateral estoppel must show: “(1) the issue is identical to one decided in the first action; (2) the issue was actually litigated in the first action; (3) resolution of the issue was essential to a final judgment in the first action; and (4) [the party against who collateral estoppel is being asserted] had a full and fair opportunity to litigate the issue in the first action.” Google, 54 F.4th at 1381. Each of these requirements appears to be met with respect to the issue of whether Kovatch discloses rankings associated with the order in which web site addresses are accessed. First, the claim limitations at issue in the two proceedings are sufficiently similar to raise the issue of collateral estoppel. See Ohio Willow Wood, 735 F.3d at 1342 (“If the differences between the unadjudicated patent claims and adjudicated patent claims do not materially alter the question of invalidity, collateral estoppel applies. . . . Thus, the mere use of different words in these portions of the claims does not create a new issue of invalidity.”). For example, claim 1 of the ’705 patent recites “a rank number assigned to each one of said web sites and stored in said database” and “access[ing] one of said web sites having the highest said rank number,” while claim 10 of the ’431 patent recites “a ranking associated with each said web site address, said ranking indicating the order in which the plurality of pre-selected web sites are accessed.” Ex. 1001, 19:58–59, 19:65–66; 846 IPR, Ex. 1001, 21:9–11.” slip op. at 18
