“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.

We disagree with Petitioner, and credit the testimony of Dr. Douglas over that of Dr. Hochwald with respect to Martin’s use of sub-windows because, as discussed below, Dr. Hochwald’s testimony is not consistent with the disclosure of Martin, while the testimony of Dr. Douglas is consistent with that disclosure. See, e.g., Ex. 1023 ¶¶ 6–9 (asserting that Martin does not expressly require sub-windows); Ex. 2002 ¶¶ 94–96 (discussing Martin’s use of at least two sub-windows for monotonic determination). 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 is directed to “techniques . . . to estimate the noise spectra or the noise characteristics for noisy speech signals” that “can be combined with a nonlinear spectral subtraction scheme.” Ex. 1005, 153. 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.

“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.

In the Decision, the Board determined that the record before it was insufficient to show that Stevens21 is a prior art printed publication under 35 U.S.C. §§ 102, 311(b) with respect to the ’948 patent. Stevens2 is one of the references relied upon in the sole asserted ground of unpatentability in the Petition. Accordingly, the Board concluded that Petitioner did not slip op. at 2

“Ex. 1005 ¶ 101. Paragraph 101 describes Figure 7. See id. ¶¶ 100, 101. Recognizing that the timing of signals DQ-Pre (between memory controller and data buffer 300 on connectors 120) and the timing of signals DQ-Post (between data buffer 300 and memory chips 200 on data lines L1 or L2) is “off” because “data DQ is buffered by the data register buffer 300,” Saito teaches that “it is required to perform a timing adjustment between the memory chips 200 and the data register buffer 300 and a timing adjustment between the data register buffer 300 and the memory controller in a separate manner.” Ex. 1005 ¶ 101. This paragraph, therefore, does not teach that retiming from CL=5 to CL=6 is based on “time intervals from the leveling operations,” as Petitioner contends. Req. Reh’g 7. To the contrary, it explicitly teaches the necessity of a “separate manner” for adjusting timing between a data buffer and memory chip (i.e., for “signals received by the each respective buffer circuit during a memory write operation,” as recited in claim 1) and adjusting timing between a data buffer and a memory controller (i.e., for “transmission of a respective set of read data signals received from the respective group of memory devices,” as recited in claim 1).” slip op. at 4

“We disagree. Neither paragraph teaches that the re-timing from CL=5 to CL=6 is “based on signals received by the each respective buffer circuit during a memory” read or write “operation,” as required by the claims. Paragraph 101 of Saito is reproduced below. Although the data DQ-Pre and the data DQ-Post have the same content, because the data DQ is buffered by the data register buffer 300, the timing is off between the data DQ-Pre and the data DQ-Post. The same is true for a relationship between the data strobe signal DQS-Pre and the data strobe signal DQS-Post. Therefore, in the present embodiment, it is required to perform a timing adjustment between the memory chips 200 and the data register buffer 300 and a timing adjustment between the data register buffer 300 and the memory controller in a separate manner. Details on the timing adjustments will be described later. Ex. 1005 ¶ 101. Paragraph 101 describes Figure 7. See id. ¶¶ 100, 101. Recognizing that the timing of signals DQ-Pre (between memory controller and data buffer 300 on connectors 120) and the timing of signals DQ-Post (between data buffer 300 and memory chips 200 on data lines L1 or L2) is “off” because “data DQ is buffered by the data register buffer 300,” Saito teaches that “it is required to perform a timing adjustment between the memory chips 200 and the data register buffer 300 and a timing adjustment between the data register buffer 300 and the memory controller in a separate manner.” Ex. 1005 ¶ 101.

“These arguments were not in the Petition so we could not have misapprehended or overlooked them. To the extent that Petitioner is arguing that these paragraphs of our Decision indicate a misapprehension of what was argued in the Petition, we disagree. Specifically, we are unpersuaded by Petitioner’s contention that Saito’s teaching to use time A to time reception of read data by “input buffer circuit INB and the like” (Ex. 1005 ¶ 149) teaches using that same interval “to time transmission” of read data, as claimed, merely because data is received by that input buffer circuit before, at some later point, being transmitted to the memory controller. Req. Reh’g. 8–9. We also are not persuaded that Saito’s use of “and the like” extends to the timing of the output of read data from buffer 300 in the manner argued. Req. Reh’g 9–11. This argument is particularly unpersuasive because, as our Decision points out (Dec. 13–14), Saito discloses an alternative to timing the output of read data from data buffer 300, which is a read leveling operation by the memory controller. Thus, although “Petitioner does not rely on those data buffer-memory controller operations for any of its arguments” (Req. Reh’g 13), they are nevertheless relevant because they corroborate that Saito does not teach its data buffer 300 using a time interval “based on signals received by [it]” for the purpose of “tim[ing] transmission of a respective set of read data signals.”” slip op. at 5
