    “F.3d at 1279–80, we begin our analysis with the Specification of the ’711 Patent. The Specification indicates when a UAV (such as the recited “reference aerial vehicle”) navigates autonomously, it flies without manual control, and can, for example, track and fly to a target using information captured onboard the vehicle itself. See Ex. 1001, 3:24–28 (“[I]t may not be desirable to manually control the interceptor aerial vehicle to follow the target UAV. In some embodiments, the interceptor aerial vehicle is able to autonomously track and fly to the target UAV using machine vision based on images captured by a camera of the interceptor aerial vehicle.”). The Specification also indicates that “autonomous” means more than just “automatic flight,” and clarifies that autonomous navigation occurs when a UAV that previously received a target location from an external source subsequently turns and flies itself towards the received location. See, e.g., id. at 4:15–17 (disclosing that the detected location of a target may be provided to an interceptor “to allow it to automatically and autonomously fly toward the direction of the detected location”); 15:64–16:3 (automatic and autonomous navigation occurs when an interceptor’s navigation component and/or flight controller receive the location of a target, and adjust the interceptor “to turn and fly towards the received location . . . based on the received location”); 16:49–60 (“For example, a flight direction and/or speed of an interceptor aerial vehicle are automatically and autonomously adjusted based on a location and size of the target within the captured image. . . . This allows the flight path of the interceptor aerial vehicle to be dynamically adjusted to track and follow a moving target.”).” slip op. at 11

    “have had reason to combine Beard and Laufer in the manner proposed by Petitioner, the combination would not satisfy the Autonomous Navigation limitation required by claim 12 because Laufer’s autopilot commands are generated by and transmitted from a remote command center (i.e., Laufer’s central controller 115). PO Resp. 15–16. In its Reply, Petitioner does not dispute that Laufer’s autopilot commands are generated by Laufer’s central controller 115, which is remote from the aircraft being controlled. See Reply 13–17. Petitioner asserts, however, that the combination still satisfies the Autonomous Navigation limitation because these autopilot commands are generated without human input. See id. Based on the complete trial record, Patent Owner’s arguments are persuasive. See PO Resp. 15–16; PO Sur-reply 42, 1–6; Ex. 2025 ¶¶ 84–87. The flight of Beard’s UAV 100 under the control of Laufer’s autopilot commands does not satisfy the Autonomous Navigation limitation of claim 12, as we have construed that limitation, because Laufer’s autopilot commands are generated at a location that is remote from UAV 100 (Laufer’s central controller 115.) See, e.g., Ex. 1010 ¶ 40 (“Central controller 115 uses autopilot command module 440 to generate autopilot aircraft commands”), ¶¶ 26, 30 (clarifying that central controller 115 and the controlled interceptor aircraft are separate devices that may communicate through a “wireless connection”), Fig. 4 (depicting “aircraft control commands 475” being generated externally from the depicted “Interceptor Aircraft”); see also Ex. 2025 ¶¶ 95–95. Petitioner never disputes that, in the proposed combination, Laufer’s central controller 115 would remain external to Beard’s UAV 100. See Reply 13–17. Instead, Petitioner relies on its proposed construction of the Autonomous Navigation limitation, which would have encompassed such an arrangement. See id. Our construction of the Autonomous Navigation limitation, which did not adopt Petitioner’s claim construction position, is dispositive of Petitioner’s argument. We thus determine that Petitioner has not shown by a preponderance of the evidence that claim 12 would have been obvious over Beard and Laufer.” slip op. at 15

Patent Owner has responded to the grounds of unpatentability involved in this proceeding by amending the claims in response to the Petition’s asserted prior art. See MTA 2, 25, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 3. No Enlargement of the Scope of the Claims An amendment may not seek to enlarge the scope of the claims of the patent. 35 U.S.C. § 316(d)(3); 37 C.F.R. §§ 42.121(b)(1)–(b)(2). Patent Owner asserts that the amendments in the Motion do not enlarge the scope of the claims of the patent because each proposed substitute claim “retains all of the limitations of the corresponding challenged claim, and each proposed independent substitute claim adds further limitations.” See MTA 2, Claims App. Petitioner does not argue otherwise.

  • 112 supportDecided for patent owner

    “Having considered the evidence and argument cited by both parties, we determine there is sufficient written description support for the disputed portions of limitations [37.e1], [37.e3,] and [37.e4]. The ’452 application discloses selecting between groups of processing schemes (e.g., algorithms) depending on a confidence level, where the groups are, for example: high cost, high robustness algorithms; medium cost, medium robustness algorithms; and low cost, low robustness algorithms. See Ex. 2019 ¶¶ 146–147. These schemes or algorithms may be neural networks. See, e.g., id. ¶ 50 (including neural network as a type of algorithm); see also id. ¶¶ 109–110); see generally MTA Opp 1 (not disputing that schemes may be neural networks). Specifically, the ’452 application describes “algorithms that process video frames of one or more video data streams,” and “produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Id. ¶ 141. The ’452 application also discloses the concept of switching between neural networks based on confidence levels. In particular, the ’452 application discloses that a “process cycles through the processing schemes to produce a detection of an object,” for example, where “if the confidence number is higher than an activation number, an action is performed to stop or change a running group (i) and select or switch to group (ii).” Id. ¶ 146. More particularly, “a processing scheme from the group of (i) High cost (low refresh rate), high robustness algorithm[s] can select a cheaper processing scheme from the group of (ii) Medium cost, medium robustness algorithms.” Id. The ’452 application additionally discloses that schemes or algorithms (e.g., neural networks) are applied to individual video frames, and that the confidence levels that determine which neural network will be applied in the future are also derived from individual video frames. For example, as discussed above, the ’452 application describes that “[t]he processing schemes produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Ex. 2019 ¶ 141 (emphases added). The ’452 application also describes selecting and applying an individual neural network, rather than only selecting and applying a group of processing schemes. For example, as highlighted above, the ’452 application describes that “a processing scheme from the” “High” group “can select a cheaper processing scheme from the” “Medium” group. Id. ¶ 146 (emphases added). In our view, these disclosures, read together, would reasonably convey to one skilled in the art that the inventor had possession of the disputed subject matter described above.

    “We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

    “The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration. We find that this evidence, including Mr. Frank- White’s declaration testimony, persuasively supports the public availability of Amira as of the date shown in the Wayback Machine URL.

    “motivated to add error processing to Garcia’s mobile phone so that it could address errors before transmitting the check image in order “to avoid wasting communications resources and adding delays.” Pet. 42. But, Petitioner does not support this rationale with a persuasive explanation or evidence. Indeed, we assume that Petitioner’s theory is that the error checking at the mobile device would have conserved bandwidth and reduced delay because it would have allowed the mobile device to identify some unsuitable images before they were sent to the payee bank; however, the Petition does not actually include an explanation to this effect. Rather, it simply states that an ordinary artisan would have known that mobile telephone networks (such as that used by Garcia) “are bandwidth and resource-constrained, and that communications over such networks takes time.” Id.; see also Ex. 1002 ¶ 115. However, all networks have bandwidth and resource constraints, and all communications take time, and neither the Petition nor Dr. Mowry explain why these considerations would have been relevant to an ordinary artisan implementing Garcia. Indeed, the Petition next asserts that “Byrne provides the requisite solution to this problem” (Pet. 42), but neither the Petition nor Dr. Mowry identify any problem. For example, Dr. Mowry does not testify that an ordinary artisan would have expected Garcia’s system to consume excessive bandwidth or incur for claim 2). In addition, Petitioner recognizes that the verification process is performed by the payee bank in Garcia, yet does not address the fact that its proposal would apparently shift a portion of the verification process to the mobile phone. See Pet. 40–44. Dr. Mowry’s trial testimony casts further doubt on Petitioner’s rationale for this claim. Dr. Mowry testifies that conserving bandwidth would “potentially” have been one of the goals of an ordinary artisan “depend[ing] on how precious their resource is.” Ex. 2020, 68:12–24. But Dr. Mowry “wouldn’t necessarily characterize [Garcia] as bandwidth intensive.” Id. at 76:13–23. In addition, he disagreed that “in the Garcia system, the motivation would have been to shift it to the client side for the verification,” noting simply that “[t]here are tradeoffs” associated with doing the verification processing on either the client or the server. Id. at 241:22– 242:13. Petitioner attempts to limit the impact of Dr. Mowry’s answers (Pet. Reply 16); however, the fact remains that Petitioner has the burden of proof, and it does not identify persuasive evidence to support its contention. Petitioner’s Reply asserts that these considerations were “particularly important in 2006, when 3G bandwidth was at a premium” (id. at 22 (citing Ex. 1029 ¶ 49)), but neither Petitioner nor Dr. Mowry provide analysis or evidence to support this conclusory assertion. Moreover, the Petition also fails to address whether the proposed combination would have, in fact, conserved communications resources or reduced delays. In Petitioner’s proposed combination, Byrne’s thin client application would be downloaded to Garcia’s mobile phone at each use (which would require communication resources and incur latency), but the Petition fails to address whether the net result of the proposed combination 148:1 (Dr. Mowry agreeing that the impact of downloading the thin client is not discussed in his report). Moreover, Garcia touts the “speed” of its process, stating that its “immediate processing . . . allows the immediate availability in the user’s account” (Ex. 1003, 7:18–8:3), which indicates that an ordinary artisan would not have perceived a problematic delay in Garcia’s system. Petitioner’s attempt to shift the burden to Patent Owner to determine whether or not its purported benefits would be realized (see Pet. Reply 17) is unavailing. In its Reply, Petitioner cites testimony from Dr. Mowry (see Ex. 1029 ¶ 37), but it simply compares the size of a compressed image with the size of a “large” application. This evidence does not outweigh the other evidence above, and it was submitted too late to remedy the Petition. See supra § II.A.; see also Trial Practice Guide 73 (explaining that a petitioner “may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability”).

    “would have been motivated to implement Garcia’s application by downloading, onto the mobile device, a thin client application, as disclosed by Byrne. See Pet. 19–25. Byrne touts the benefits of downloading a thin client rather than storing an application on a user’s device (Ex. 1004 ¶¶ 45– 46; see also id. ¶¶ 47–48), and Dr. Mowry testifies that an ordinary artisan would have understood downloading a thin client to be a well-known way of distributing software in the relevant time period and suited for mobile devices (Ex. 1002 ¶¶ 64–65, 70). In addition, Dr. Mowry testifies that a thin client improves security and ease of software maintenance.

See supra § II.A; Pet. Reply 15–16 (noting that the Response had not addressed these issues). Moreover, even if this argument had been properly raised, it would not be persuasive because Patent Owner does not identify persuasive evidence to support its position. See, e.g., Icon Health & Fitness, Inc. v. Strava, Inc., 849 F.3d 1034, 1043 (Fed. Cir. 2017) (“Attorney argument is not evidence.”). (Garcia’s mobile phone) with predictable results. We are also persuaded that a person of ordinary skill in the art would have been motivated to implement Garcia’s application such that the application provides a user-interface and controls the image capture device, as disclosed by Byrne. See, e.g., Pet. 22–23. Garcia suggests that the application should perform these functions (see Ex. 1003, 5:1–6:10, 9:19– 10:18), and we credit Dr. Mowry’s testimony that an ordinary artisan would find this desirable (see Ex. 1002 ¶¶ 65, 67). Moreover, the references lend themselves to the combination because Garcia and Byrne both describe remotely depositing a check via the Internet using software on a user’s device that opens an interactive session, and both perform substantially similar steps. See Pet. 22–23; Ex. 1003, 9:21–10:3, 10:10–18, 11:7–15; Ex. 1004 ¶¶ 41, 48, 174–175, 177–178. Finally, Dr. Mowry testifies that the ordinary artisan would have had a reasonable expectation of success in implementing the combination, and he provides supporting analysis and evidence.

    “Although the dictionary defines “periodically” as “from time to time” or “at regular intervals of time,” based on the record before us, we agree with Patent Owner that its proposed construction is how one skilled in the art would have understood that term in the context of the ’345 patent Specification. Turning first to the intrinsic evidence, the Specification explains that “[t]he future and current minimum values are calculated continuously and initiated periodically, for example, every 5 seconds.” Ex. 1001, 8:37–39. Although the Specification later notes that “[i]t will be appreciated that, while specific values are used as in the several equations and calculations employed in the present invention, these values may be different than those shown” (id. at 8:64–67), this passage does not mean that the Specification contemplates arrangements where “periodically” is simply “from time to time.” Rather, we determine that statement from the Specification indicates that the specific amount of time (i.e., every 5 seconds) may vary. Turning now to the extrinsic evidence, the testimony of Dr. Douglas supports our conclusion, explaining that “at regular intervals of time” is the “only . . . definition . . . consistent with the understanding of a person skilled in the art in light of the specification of the ’345 Patent and its use in the particular field of audio signal processing” because [l]ike the “period” of an audio signal itself, which is the amount of time it takes for a signal to repeat itself, “periodically” as recited in claims 6 and 9 and throughout the remainder of the specification of the ’345 Patent refers to actions that occur at regular intervals (e.g., every 5 seconds rather than merely “from time to time”). Ex. 2002 ¶ 48. Moreover, Petitioner’s declarant, Dr. Hochwald testifies that outside of the context of the ’345 patent Specification, “periodically” means “at regular time intervals” (Ex. 2005, 99:13–15), and when asked about that term’s meaning in the context of the ’345 patent Specification, Dr. Hochwald simply noted that “all I can do is read what it says,” which is that “[i]t’s doing something periodically, for example, every five seconds” (id. at 100:4–6). Accordingly, the testimony from Dr. Douglas, as well as that from Dr. Hochwald, supports Patent Owner’s construction. In summary, we adopt Patent Owner’s construction of “periodically,” requiring “at regular intervals of time,” because (1) this is consistent with how this term is used in the context of the ’345 Patent Specification; and (2) this is supported by the testimony of both experts.” slip op. at 7

    “Patent Owner responds that, because Helf uses average values (i.e., the average of eight consecutive values), it does not disclose using a minimum value. PO Resp. 17–23. Patent Owner acknowledges that the ’345 patent, itself, uses a “smoothing process [that] produces frequency bins with multiple smoothed magnitude values, ultimately finding the minimum of all of the values,” but contends that “Helf’s averaging process produces a single output representing one average of the original samples.” Id. at 20–21 (underlining omitted) (citing Ex. 1001, 8:14–28; Ex. 2002 ¶¶ 52, 63–72). We disagree with Patent Owner’s characterization of the differences between Helf and the ’345 patent. While Helf may ultimately produce a single minimum value, as discussed above, that value is based on a minimum value of the averages calculated over the given time period. At oral hearing, Patent Owner acknowledged that Helf determines many averages values (i.e., the averages of the eight consecutive frames) and determines a minimum of those values. See, e.g., Tr. 22:2–6. The claim simply requires a “future minimum value,” and does not preclude that value from being a minimum value taken from a set of average values. Indeed, such an interpretation of the claim would be inconsistent with the ’345 patent’s use of smoothed values noted by Patent Owner. Ex. 1001, 8:14–28. The testimony of Dr. Douglas cited by Patent Owner does not convince us otherwise. See Ex. 2002 ¶¶ 52, 63–72 (effectively repeating Patent Owner’s contentions, which are unpersuasive for the reasons set forth above).

    “With respect to its “running minimum estimator,” Helf explains that the “running minimum estimator” is used “when either the speech signal is never absent for more than a second or the background noise itself is never constant in spectral shape.” Ex. 1010, 8:11–15. Helf acknowledges that its “running minimum estimator” is “much less accura[te]” than its “stationary estimator,” which is typically used for background noise estimates. Id. at 8:15–17. As a result, Helf only uses its “running minimum estimator” if “[i]t has been more than 10 seconds since the last update of the background noise spectral estimate due to the Stationary Estimator,” and “[t]he difference, D, between the past background noise estimate, which may have resulted from the Stationary Estimator or the Running Minimum Estimator, and the current Running Minimum Estimator is great.” Id. at 8:32–42. We see no persuasive reason to set Helf’s current background noise estimate (Nk and Ck, considered the “current minimum” by Petitioner) to the minimum estimate (Mk) from the “running minimum estimator” (considered the “future minimum” by Petitioner). The testimony of Dr. Douglas supports this conclusion. See, e.g., Ex. 2002 ¶¶ 119, 120. Addressing the portions of Helf noted above, Dr. Douglas testifies that “Helf only relies on Mk in a ‘worst case’ scenario” and “disfavors the use of Mk, even where Bk is unavailable,” and concludes that “one of ordinary skill would not be motivated to force the use of the disfavored Mk every ten seconds even where the much more accurate Bk estimate is available.” Id. ¶ 119. Dr. Douglas further testifies that “one of ordinary skill would not have been motivated to abandon[] the comparison of D to a threshold” because “one of ordinary skill in the art would recognize that Helf is a signal-dependent system, and it would not abandon its ability to adapt to varying signal conditions in favor of a blind periodic update using a disfavored estimate.” Id. ¶ 120. We credit the testimony of Dr. Douglas over that of Dr. Hochwald in this regard. See Ex. 1004 ¶¶ 157–159; Ex. 2002 ¶¶ 115–120. The testimony from Dr. Douglas is consistent with the disclosure of Helf, while that of Dr. Hochwald is based on conclusory statements. For example, the only portions of Dr. Hochwald’s testimony cited in the Petition in connection with the rationale provided in this challenge are conclusory statements that “[a] person of ordinary skill would have found it obvious to modify Helf to update the background noise estimate after every 10 second period based on the teachings of Martin,” and “[t]he skilled person would have recognized it was beneficial to periodically update the minimum noise value to ensure it accurately reflected the current noise level,” which are contrary to the disclosure of Helf noted above.

As noted above, Martin’s algorithm requires a determination of whether or not “the minimum power of the last W windows with M samples each is monotonically increasing.” Ex. 1006, 1094. We are not persuaded by Petitioner’s argument that one skilled in the art would have found it obvious to modify Hirsch’s system based on a scenario from Martin where W = 1 because such a scenario is counter to the entire purpose of Martin. Even Petitioner’s Declarant, Dr. Hochwald, acknowledges that a single data point (i.e., W = 1) cannot be used to determine whether something is monotonically increasing.

Hirsch discusses use of an “adaptive threshold” for each frequency bin to distinguish between speech and noise (Ex. 1005, 153), which Petitioner cites as corresponding to the “setting a threshold for each frequency bin using a noise estimation process” recited in claim 1 (Pet. 27). Hirsch describes comparing spectral components to their corresponding thresholds to determine if speech is present (Ex. 1005, 153), which Petitioner cites as corresponding to the “detecting for each frequency bin whether the magnitude of the frequency bin is less than the corresponding threshold, thereby detecting the position of noise elements for each frequency bin” recited in claim 1 (Pet. 27–28). Based on the record before us, we are persuaded that Hirsch discloses each and every element of claim 1. We also are persuaded that Hirsch discloses each and every element of claim 38 for the reasons discussed above in connection with claim 1, as well as the “subtracting said noise elements . . . from said audio signal” additionally recited in claim 38. With respect to the recited “subtracting,” Petitioner cites Hirsch’s discussion of spectral subtraction. Pet. 25–26 (citing Ex. 1005, 153–155). As Petitioner notes, “[t]he spectral subtraction technique shown in Hirsch subtracts the noise estimate from each sub-band or ‘bin’ and sets any negative values to zero” (id. (citing Ex. 1005, 153)), which “is the same technique used in the ’345 patent” (id. (citing Ex. 1001, 6:58–61, 7:16–27)). Claims 2, 3, 12, 13, 21, and 23 depend from claim 1, and Petitioner cites to relevant portions of Hirsch as disclosing the additional limitations of those claims. See Pet. 28–31. We are persuaded by Petitioner’s unrebutted arguments and evidence related to how Hirsch properly accounts for each and every element of these dependent claims, which we adopt for purposes of this decision. Specifically, we find that Hirsch discloses the additional limitations recited in those claims based on the citations to Hirsch therein and the supporting expert testimony. See id. Based on our review of the record before us, the preponderance of the evidence supports Petitioner’s contentions that claims 1–3, 12, 13, 21, 23, and 38 are anticipated by Hirsch.” slip op. at 7

    “Initially, we agree with Petitioner that one skilled in the art would have considered Martin’s teachings, generally, when reviewing the teachings of Hirsch, as Martin is specifically referenced in Hirsch itself. Nevertheless, we are not persuaded that one skilled in the art would have modified Hisch’s system based on the teachings of Martin in the particular manner proposed by Petitioner. Consistent with Patent Owner’s contentions noted above, Martin describes determining “[t]he noise power estimate is based on the minimum of signal power within a window of L samples” and “[f]or reasons of computational complexity and delay the data window of length L is decomposed into W windows of length M such that M * W = L,” and provides an example where W=4. Ex. 1006, 1094. Martin distinguishes between “slowly varying noise power” and “rapidly varying noise power” to determine its noise power estimate, with a determination of whether the minimum power in successive sub-windows is monotonically increasing central to its estimation. Id. “If the minimum power of the last W windows with M samples each is monotonically increasing we decide on rapid noise power variation” and “the noise power estimate equals the power minimum of the last M samples Pn(i) = PMmin(i = r * M).” Id. “In case of non monotonic power the noise power estimate is set to the minimum of the length L window.” Id. Regardless of whether the noise power calculation is that for “slowly varying noise power” or “rapidly varying noise power,” Martin requires that first a determination is made as to whether or not “the minimum power of the last W windows with M samples each is monotonically increasing.” Id. (emphasis added). To the extent there can be any dispute on this issue, the testimony from Dr. Douglas supports the understanding that at least two subwindows are required to determine which noise power calculation to use. See Ex. 2002 ¶¶ 95, 96. In its Reply, Petitioner contends that, “[i]n this configuration [where” slip op. at 13
