    “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

    “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.

Pet. 16 (citing Ex. 1102 ¶ 49). In our Institution Decision, we found Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the prior art of record, see Okajima v.

Neither Patent Owner, in its Response, nor Dr. Annavaram, in his declaration, proposes a level of ordinary skill in the art.

    “To the extent Patent Owner argues that these particularized selection clauses recited in different claims must have the same or similar meaning because they all use the word “selecting” (see PO Resp. 28–29), we disagree with Patent Owner. See IGT v. Bally Gaming Int’l, Inc., 659 F.3d 1109, 1117 (Fed. Cir. 2011) (“We caution that claim language must be construed in the context of the claim in which it appears. Extracting a single word from a claim divorced from the surrounding limitations can lead construction astray. Claim language must be construed in the claim in which it appears.” (emphasis added)). The selection clauses recited in these claims are plainly different on the face of the claims when considering the material differences in the claim language set forth above. According the same meaning to the limitations that recite “select . . . based on” indicators, “select . . . when” certain conditions are met, and “select . . . out of a group” of values would be improper because it would blur the material differences in the claim language recited expressly in the claims. Instead, we interpret the selection clauses recited in the challenged claims “in the context of the particular claim in which the disputed term appears” and “in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. In other words, we do not construe the single word “selecting” in isolation, but, rather, interpret the full selection clauses recited in the challenged claims in the context of the entire patent. Claim 13 recites “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator.” In our view, the plain meaning of this limitation is clear on the face of the claim—a value of a control signal is selected based on two indicators, the mode indicator and the leakage indicator.” slip op. at 14

    “Tr. 47:7–23. Because the output of Kim’s NAND gates will be different depending on the value of Kim’s memory cells C1–CN allowed to “pass through,” we agree with Petitioner that the value of Kim’s memory cells C1– CN (the claimed “leakage indicator”) “plays a role” in deciding what the output of Kim’s NAND gates (the claimed “value of the control signal”) will be. Moreover, Patent Owner acknowledged that the output of Kim’s NAND gate is determined based on the inputs to the NAND gates (i.e., the sleep signal input and the memory cell signal input). JUDGE CHUNG: But, knowing a little bit about how a NAND gate works, isn’t it the case that the input to the NAND gates, G1 through GN, with the input of the sleep signal and the C1 through CN signal, isn’t it the case that input to the NAND gate determines what the output is? MS. ZHONG: Okay. So any logic gate, the output will depend on the input. That’s for sure. Tr. 44:18–25; but see id. at 45:3–10 (stating that even if the “output is in control of the input, . . . that does not mean the selection is based on that input”). Thus, we find that Kim’s NAND gate (the claimed “control circuit”) operates to determine its output (the claimed “value of the control signal”) based on its input of the sleep signal (the claimed “mode indicator”) and the memory cell value input (the claimed “leakage indicator”). As discussed in Section III.B, the Specification indicates that “select[ing] the value of the control signal based on the mode indicator and on the leakage indicator” recited in claim 13 is synonymous to determining the value based on the recited indicators. See Ex. 1101, 4:4–11. Thus, the evidence of record shows that Kim teaches “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator,” as recited in claim 13.” slip op. at 44

    “We are not persuaded by Petitioner’s argument and evidence. First, although Petitioner proposes “[s]ubstituting Lee’s inputs of leakage current and temperature for generating a power gate control signal” (i.e., Lee’s “control signal (BIAS)”) for “Kim’s inputs of leakage current and other ‘stimuli’ for generating a power gate control signal” (Pet. 64 (citing Ex. 1102 ¶ 115)), neither Petitioner nor Dr. Harris explains adequately how they are proposing to “substitute” Kim’s control signal with Lee’s “control signal (BIAS).” For example, Figure A reproduced above does not show how Petitioner or Dr. Harris proposes to use Lee’s “control signal (BIAS)” in the proposed combination. Petitioner asserts that “[a]lthough Lee’s control signal is analog and Kim’s control signal is digital, it was well known to apply teachings in an analog domain to a digital domain, and conversions between analog and digital domains were easy to implement.” Pet. 66 (emphases added) (citing Ex. 1102 ¶ 121; Ex. 1115). Dr. Harris similarly states that Figures A and B show examples of obvious ways to use in Kim’s system Lee’s teaching of setting conductance of the array based on temperature. A POSA would have found both of these ways obvious. That Lee uses an analog control signal and Kim uses a digital control signal would have presented no obstacle to a POSA. . . . That is, converting analog circuit elements and signals to digital was well known long before the ’026 patent. Ex. 1102 ¶ 121 (emphases added) (citing (Ex. 1115) (“Analog-to-digital converters (ADC’s) are ubiquitous, critical components of software radio and other signal processing systems.”)). But Dr. Harris does not explain adequately how “to use in Kim’s system” the digitized BIAS signal of Lee. See id. The only additional input signal shown in Figure A compared to Figure 4 of Kim is the temperature line that has the value of 0 when the temperature is cold and the value of 1 when the temperature is hot. See Ex. 1102 ¶ 116 (Fig. A). There is no explanation of how the modified teaching of the BIAS signal of Lee (i.e., modified or converted to a digital signal) would have worked in the proposed combination of Figure A.” slip op. at 69

Pet. 29 (citing Ex. 1010 ¶¶ 102–103).16 We afford this evidence little weight for several reasons. First, the video does not show the strut or the bending of a strut. See Ex. 1018.

Reply 15–16 (citing Ex. 1058, 1– 12; Ex. 1010 ¶¶ 77–82). We must base our decision in this case on the arguments and evidence presented.

Id. Thus, from the video, it is unknown whether the skirt panel is attached to the trailer by one strut, multiple struts, or additional features. Second, Petitioner does not identify clearly how the tested system precisely corresponds to the teachings of Layfield. For example, Patent Owner raises a number of issues with the struts and panels in the video to which Petitioner provides either no response or an unconvincing response. For example, Patent Owner argues that each embodiment of Layfield uses trusses 36 to “interconnect each skirt panel and reinforce the panel assembly,” while it is asserted that the skirt panels in the video do not have trusses and are not interconnected.

    “components (see, e.g., id. at 17:1–10), Layfield does not contain any express disclosure concerning the flexibility of the struts. Nor does Layfield include any discussion about the desirability of strut flexibility. The closest Layfield comes to discussing flexibility of the struts is by frequently referring to the struts as “support struts” (see, e.g., id. at 18:40) and discussing the use of a “bracket means,” which is on the struts, to “rigidly secure” the skirt panels to the trailer (id. at 6:48–49). Further, Layfield’s detailed discussion of the embodiment of support strut 58 shown in Figure 10, reproduced below, highlights the bracing and reinforcement features. Figure 10, above, shows the construction detail of a support strut 58. Ex. 1004, 15:45. Specifically, Layfield discloses that strut 58 includes “a pair of spaced-apart vertical members 160, which are braced by horizontal cross-members 162” and “reinforcing rectangular lattice 170.” Id. at 15:46– 54. Thus, we agree with Patent Owner’s argument that “Layfield does not expressly teach that the ‘support struts 58’ are ‘resilient.’” PO Resp. 42 (citing Ex. 2001 ¶¶ 148–149). We reiterate that Petitioner’s first challenge is based on anticipation. Thus, Petitioner must show that resilient struts are “either expressly or inherently described, in” Layfield. Verdegaal Bros. Inc., 814 F.2d at 631; see also PO Resp. 42. In its Reply Brief and at the oral hearing, Petitioner contends that its challenge is based on express disclosure, not inherency. See Pet. Reply 17–18; Tr. 9:21–11:4 (arguing that “this is not a case of inherency”). Petitioner contends one of ordinary skill in the art “would have understood, based upon Layfield’s express disclosures concerning the material, structure, and connection of the strut, that the Layfield strut is resilient and can sustain significant and substantial elastic deformation.” Pet. Reply 18 (citing REG Synthetic Fuels, LLC v. Neste Oil Oyj, 841 F.3d 954, 960–61 (Fed. Cir. 2016)). Whether we analyze Petitioner’s argument based on express disclosure or inherency, we reach the same result. To begin, although we agree with Petitioner that a prior art reference “need not satisfy an ipsissimis verbis test” (Pet. Reply 17 (quoting In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir. 2009))), there is no express statement that Layfield’s strut is resilient or otherwise exhibits a characteristic synonymous with resiliency. Additionally, we do not agree that Petitioner’s reliance on the thermoplastic materials, disclosed by Layfield for construction of the strut, establishes whether the strut is resilient and capable of elastic deformation. The evidence submitted by the parties is contradictory as to whether one of ordinary skill in the art would have understood Layfield’s struts to be resilient based on the material alone.15 Compare Ex. 1010 ¶¶ 74–82 15 Petitioner also points to a finding by the examiner, during prosecution of the ’017 patent application, that an aluminum strut was resilient, and argues (Mr. Tres opining as to the materials disclosed by Layfield), with Ex. 2001 ¶¶ 160–164 (Dr. Micklow contradicting Mr. Tres’s testimony regarding the materials disclosed by Layfield). Further, the evidence is contradictory as to whether one of ordinary skill in the art would have understood from the design of Layfield’s strut, specifically the taper design and mechanism by which the strut connects to the trailer I-beam, that the strut is resilient. Compare Ex. 1010 ¶¶ 83–90 (Mr. Tres’s testimony regarding the design and connection mechanism), with Ex. 2001 ¶¶ 165–175 (Dr. Micklow’s contradictory testimony). Turning to Petitioner’s video (Ex. 1018), Petitioner asserts testing of commercial versions of the Layfield fairing illustrates what one skilled in the art would have understood from Layfield itself, namely that the Layfield strut is adapted to sustain an elastic deformation when a load is applied to the resilient strut when the skirt panel moves away from the configuration reducing air drag about the trailer and to self-recover the resilient strut original shape when the load is removed. Pet. 29 (citing Ex. 1010 ¶¶ 102–103).16 We afford this evidence little weight for several reasons. First, the video does not show the strut or the bending of a strut. See Ex. 1018.

    “Additionally, Patent Owner similarly contends that the modifications proposed are redundant of Layfield’s “flexible lower panel 20,” which already “allow[s] flexing when impacting a road object.” PO Resp. 59 (citing Ex. 1004, 14:13–18); see PO Sur-reply 26–27. We disagree. Again, the proposed modifications here are to Layfield’s struts. In the context of Petitioner’s anticipation challenge, we agreed with Patent Owner and found that Petitioner had not established sufficiently on the record that Layfield’s struts were resilient. See supra, § II.D.a.i., ii. Therefore, the proposed modification addressed here, to make Layfield’s struts resilient, does not duplicate the objective of Layfield’s flexible lower panel 20 at least because (a) Layfield’s struts are a different structure than lower panel 20 and (b) modification of Layfield’s struts would provide greater impact protection to other panels aside from just lower panel 20. See Pet. Reply 26–27 (One of ordinary skill in the art “would have been motivated to do so because Rinard and Layfield both seek to provide fairing panels with ‘sufficient flexibility’ to bend when encountering objects.” (citing Ex. 1004, 12:67– 13:4; Ex. 1006, 10:43–50; Ex. 1055 ¶ 47)). We determine that Petitioner has shown that one of ordinary skill in the art would have had a reason with rational underpinning to look to other similar types of trailer components that are flexible to make further improvements to Layfield’s design. See KSR, 550 U.S. at 417 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.”). Third, Patent Owner contends one of ordinary skill in the art “would not have a reasonable expectation of success at achieving the claimed technology by looking to the vertical supports of Rinard’s air scoops to modify the Layfield skirt panels 10 and support struts 58.” PO Resp. 61 (citing Ex. 2001 ¶¶ 237–240). Patent Owner asserts that because Layfield’s upper skirt panels are rigid and non-moving one of ordinary skill in the art “would not reasonably expect the hypothetical modified panels (with their reinforcing trusses 36) to move.” Id. Patent Owner also argues that Rinard teaches “an upper skirt panel that is rigid and non-moving” and so it is not reasonable to expect modifying Layfield as proposed would somehow cause Layfield’s fixed skirt panels to be able to move as claimed. PO Sur-reply 27–28 (citations omitted). We disagree for the same reasons discussed above—namely, we find Layfield’s upper skirt panels to be resilient. Therefore, one of ordinary skill in the art would have a reasonable expectation of success in achieving a resilient strut adapted as claimed by modifying Layfield’s strut in light of Rinard, for the reasons proposed by Petitioner. See Pet. Reply 27 (“Applying this solution to the Layfield skirt panel and struts would yield the predictable result of allowing the Layfield skirt panel 10 and struts 58 to absorb greater impacts without having to be repaired or replaced.” (citing Ex. 1021, 7–8, 11–12)).” slip op. at 42

    “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). Accordingly, we are persuaded that Helf’s minimum value (Mk) corresponds to the “future minimum value” recited in claims 4 and 39.” slip op. at 13

    “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. See Ex. 2005 69:10–17 (explaining that you need at least two data points to make such a determination, meaning W ≥ 2).

Hirsch discusses use of “FFT based spectral analysis” (id. at 154), for example, which Petitioner cites as corresponding to the “generating the frequency spectrum of said audio signal thereby generating frequency bins of said audio signal” recited in claim 1 (Pet. 27). 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
