    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “II. ANALYSIS A. LEVEL OF ORDINARY SKILL IN THE ART Petitioner proposes that a person of ordinary skill would have been knowledgeable regarding liquid cooling systems for computer systems, would have had a Bachelor of Science (B.S.) in electrical or mechanical engineering, or similar advanced post-graduate education in this area, or would have possessed at least 2–3 years of experience in liquid cooling systems for computer systems or similar systems. A POSITA would be knowledgeable of the concepts, components, and their functions described as “prior art” in the ’355 patent such as, e.g., pumps, radiators, fans, reservoirs, and other techniques of heat dissipation and liquid cooling. (Ex- 1001,1:11–47.) In addition, a POSITA would be knowledgeable about electric motors and their components (e.g., electromagnetic coils, rotors, stators, AC/DC motors, etc.) Pet. 6–7 (citing Ex. 1003 ¶¶ 13–18). Patent Owner has not proposed a level of ordinary skill in the art. We adopt Petitioner’s proposed level of ordinary skill as it appears to be consistent with the level of skill reflected by the specification and in the asserted prior art references.” slip op. at 9

      “disclosures. Pet. 17–45. Petitioner maps the claimed reservoir to Duan’s “structure formed by an accommodation chamber 21, lower cover 225, cap 3, and cooling plate 1.” Id. at 18. Petitioner maps the claimed double-sided chassis to Duan’s accommodation chamber 21 and the claimed impeller cover to Duan’s lower cover 225. Id. at 22–27. Petitioner maps the claimed thermal-exchange chamber to Duan’s cap 3 and cooling plate 1, with heat-absorbing face 11 and cooling plate 1 corresponding to the claimed heat exchanging interface. Id. at 27–36. Petitioner maps the claimed radiator to Duan’s cooling stage 53. Id. at 36–39. Petitioner asserts that Duan’s inlet is “below a center of the impeller” because it is along the axis about which the impeller rotates. Id. at 39–41. Petitioner asserts that Duan’s lower cover 225 defines an outlet tangential to the impeller’s circumference. Id. at 41–45. In summary, Petitioner asserts that Duan, without modification, discloses all of claim 1’s limitations. Patent Owner does not challenge Petitioner’s contentions, as it has filed no Patent Owner Response. We have reviewed Petitioner’s contentions and conclude that they show by a preponderance of the evidence that claim 1’s subject matter would have been obvious over Duan. See Pet. 17– 45. We adopt Petition’s unchallenged contentions as our analysis.” slip op. at 11

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundUnpatentable

      “As to claim 5, Petitioner asserts that it would have been obvious to use Wu’s approach to securing chassis and heat-exchanging interface to the heat generating component, because Duan discusses the need to assemble its components but does not provide detailed instruction. Id. Thus, the modification would provide the benefit of securing Duan’s cooling plate module and cooling plate to the CPU. Id. at 72. For claim 8, Petitioner asserts that it would have been obvious to use Wu’s approach to blowing air through the radiator using a fan driven by a motor separate from the pump’s motor. Id. at 72–73. Petitioner reasons that doing so would improve Duan’s performance by increasing heat dissipation. Id. at 74. We agree that Petitioner’s contentions support the modification with rational underpinning.” slip op. at 12

      “involved two petitioners accused of infringement based on the same product—made by one petitioner and incorporating technology licensed from the other. Valve I, at 9–10 (finding a significant relationship between the two petitioners “with respect to Patent Owner’s assertion” of the challenged patent); Valve II, at 10 (same); see Prelim. Reply 3. Patent Owner has asserted no such relationship here, and we conclude that Patent Owner has failed to establish that Petitioner has a significant relationship with the -522 IPR petitioner. Representation by the same counsel and being accused of infringing the same patent does not create a relationship that justifies discretionarily denying institution.

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “Synthes USA, LLC v. Spinal Kinetics, Inc., 734 F.3d 1332, 1344 (Fed. Cir. 2013). And, although there are no bright-line rules for the amount of disclosure needed in an unpredictable art, that amount “necessarily changes with each invention” and “changes with progress in the field.” Ariad, 598 F.3d at 1351. Here, we find that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. Thus, we conclude that the ’525 application requires a more-detailed disclosure than would be required in a predictable field to adequately demonstrate possession of a heat-transfer composition consisting essentially of HFO-1234yf and PAG for use in AAC. (iii) Disclosure in the ’525 Application With these background findings in mind, we now turn to the four corners of the ’525 application—and we find that the ’525 application does not contain the detailed disclosure needed in this case to reasonably convey possession of a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for use in AAC.” slip op. at 37

      “develops new refrigerants for use as heat transfer fluids. Ex. 1002 ¶ 149. Such a person would have had a Ph.D. in Chemistry, Chemical Engineering, Mechanical Engineering, Material Science, or a related field or discipline and at least 3 to 5 years of experience, or alternatively an M.S. degree and 5 to 10 years of experience. Id. Patent Owner’s Declarant, Dr. Bivens, provides a similar description of the person of ordinary skill in the art, stating that such a person would have a B.S. degree in Chemical Engineering or Chemistry, and five years of work experience, or a Ph.D. or M.S. degree and 2–3 years of experience. Ex. 2001 ¶ 23. Based on these descriptions, we find that the parties’ definitions of ordinary skill in the art are substantially the same, and agree with the parties that an ordinarily skilled artisan would be educated in the Chemical and Chemical Engineering arts or related disciplines. We also agree with the parties that a person having less formal education, such as a B.S. or M.S. degree, would require more years of experience than a person with more formal education, such as a Ph.D., to qualify as an ordinarily skilled artisan. We also find that neither party states how any difference in the parties’ articulated levels of skill impacts this proceeding. Thus, our analysis would be the same regardless of any minor differences between the parties’ respective articulations. Finally, we note that the level of ordinary skill in the art is reflected by the prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Tr. 114:15–115:18 (emphases added). Thus, we find that Patent Owner does not contest that a heat-transfer composition consisting essentially of HFO- 1234yf and PAG for AAC was in public commercial use before the March 26, 2014, filing date of the ’017 patent. Accordingly, we find that Petitioner’s evidence, together with Patent Owner’s concessions, demonstrates by a preponderance of evidence that the claimed subject matter of the ’017 patent was in commercial use before its March 26, 2014, effective filing date. See Ex. 1002 ¶¶ 399–409. In particular, as to claims 1, 3–10, 12, 13, and 15–20, we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant AAC composition of the Ford Transit Custom Bus, the Mazda CX 5 (2.0i and 2.2D), and the Opel Mocca used HFO-1234yf and a PAG lubricant as early as 2012. Ex. 1002 ¶ 399 (citing Ex. 101324, 2, 38, 55, 70). We also credit Dr. Brown’s 24 Behr Hella Services, Refrigerant and Oil Filling Quantities Passenger Cars & Commercial Vehicles 2014–15. PGR12 Ex. 1013. (“Service Guide”). PGR12 Ex. 1013. The Service Guide provides tables setting forth specifications for refrigerant type, refrigerant quantity, vehicle manufacturers’ original equipment compressor oil type, and oil filling quantity for the air-conditioning system of each vehicle listed in the tables. Id. at 2–3. Petitioner and Dr. Brown direct us to the Sevice Guide’s entries calculations, which show that the Ford Transit Custom Bus had an AAC refrigerant-lubricant composition of 26.7% of PAG lubricant and 73.3% of HFO-1234yf (Ex. 1002 ¶ 401 (citing Ex. 1013, 38)); the Mazda CX 5 2.0i had 16.7% PAG lubricant and 83.3% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 55)); the Mazda CX 5 2.2D had a 17.5% PAG lubricant and 82.5% HFO-1234yf (id.); and the Opal Mocca had 11.6% PAG lubricant and 88.4% HFO-1234yf (Ex. 1002 ¶ 402 (citing Ex. 1013, 70)). As to dependent claims 2, 11, and 14, which all require that the lubricant is present “in an amount from about 30% to about 50% weight,” we credit Dr. Brown’s uncontested testimony that the refrigerant-lubricant composition of the Ford Transit Custom Bus recited lubricant amount. Ex. 1002 ¶ 403. In particular, we agree with Dr. Brown that, because the lubricant accounts for 26.7% of the AAC refrigerant-lubricant composition in the Ford Transit Custom Bus, the lubricant makes up “about 30%” of the refrigerant-lubricant composition as claimed. Id. For these reasons, we find that Petitioner has met its burden to show that claims 1–20 are unpatentable for anticipation under § 102(a)(1).” slip op. at 55

      “We agree with Petitioner that the ’525 application’s statement that the compounds are “adaptable for use” weighs against a finding of adequate written description. First, “adaptable for use” is vague, as Dr. Bivens acknowledges. See Ex. 1177, 151:15 (testifying that “adaptable for use can have a wide range of meaning”). Second, the ’525 application gives no direction on how a skilled artisan would need to adapt any particular composition for use in AAC, or even if any “adaptation” was necessary. We find that such a teaching is important in this case to show that the inventors had possession of the claimed invention, given our findings above that the art of AAC was unpredictable and that a heat-transfer composition for AAC required specific technical features that were unpredictable and unexpected. For completeness, we again reject Patent Owner’s argument that “[t]o show the inventors possessed claim 1 requires no more” than the statement in the written description that “‘the compositions of the present invention are believed to be adaptable . . . with or without system modification.’” PGR12 Resp. 27–28 (quoting Ex. 1001, 7:4–8). Regardless of the exact wording of claim 1, the inventors “still [had to have] describe[d] some way of performing the claimed methods.” Ariad, 598 F.3d at 1355. And here, with merely a passing reference to AAC, the ’525 application fails to provide any credible “technologic knowledge” to demonstrate to an ordinarily skilled artisan that Patent Owner “was in possession of the invention that is claimed.” Id.” slip op. at 43

      “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.

      “In its Reply, Petitioner contends that, “[i]n this configuration [where W = 1], any purported distinction between windows and sub-windows in Martin vanishes and [Patent Owner]’s argument is irrelevant,” acknowledging that the proposed modification eliminates Martin’s sub-windows. Pet. Reply 5. Petitioner further contends that Patent Owner “incorrectly argues that the use of sub-windows is central to Martin’s algorithm” and “[n]othing in Martin suggests that the use of sub-windows is required.” Id. at 7 (citing Ex. 1023 ¶¶ 6–8). 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). Petitioner fails to provide persuasive reasoning as to why one skilled in the art would have modified Hirsch’s teachings in a manner that is contrary to the express disclosure of Martin.” slip op. at 14

      “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. 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.
