      “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

      “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

      “We find Dr. Tamassia’s testimony as to public accessibility of RFCs in general to be credible, especially given the independent support of RFC 2026 (Ex. 1036), the contents of which Patent Owner does not challenge.7 As part of routine discovery, see 37 C.F.R. § 42.51(b)(1)(ii), Patent Owner had the opportunity to cross-examine Dr. Tamassia, but does not point us to any discussion of this issue. Moreover, RFC 2401’s contents are consistent with the publication process described by RFC 2026 and Dr. Tamassia, including the inclusion of a date “November 1998” on the top right corner of the first page of the document. Ex. 1008, 1. In addition, this document—a request for suggestions and improvements for an Internet standards protocol, 7 As addressed below, Patent Owner objects and moves to dismiss a number of Exhibits based on hearsay and relevancy. See Paper 20 (Motion to Exclude). having no indication of being a mere draft or internal paper—is precisely the type of document whose very purpose is public disclosure, including on the Internet. Both of the magazine articles, Exhibits 1064 and 1065, further corroborate the indicia of availability on the face of RFC 2401, although they are not necessary to our finding of public accessibility. We do not rely on the testimony of Sandy Ginoza, Exhibits 1060 and 1063, which Patent Owner seeks to exclude as discussed further below.” slip op. at 12

    • Expert testimonyPetitioner expert creditedDecided for petitioner

      “Patent Owner does not articulate a persuasive reason for giving Dr. Tamassia’s declaration, as a whole, little or no weight in our analysis. We agree with Petitioner that experts are not required to opine on every relevant factual and legal issue in order to be accorded substantial weight. The cases upon which Patent Owner relies do not show otherwise. For example, Patent Owner cites Schumer v. Laboratory Computer Systems, Inc., 308 F.3d 1304, 1315 (Fed. Cir. 2002), for the proposition that “[expert] testimony . . . ‘must identify each claim element, state the witnesses’ interpretation of the claim element, and explain in detail how each claim element is disclosed in the prior art reference.’” PO Resp. 52–53. Patent Owner’s quotation, however, mischaracterizes Schumer by omitting introductory words necessary to the meaning of the quoted sentence. In its entirety, the quoted portion of Schumer states the following: Typically, testimony concerning anticipation must be testimony from one skilled in the art and must identify each claim element, state the witnesses’ interpretation of the claim element, and explain in detail how each claim element is disclosed in the prior art reference. The testimony is insufficient if it is merely conclusory. Schumer, 308 F.3d at 1315–16. The Federal Circuit then adds that it is not the task of the courts to “attempt to interpret confusing or general testimony to determine whether a case of invalidity has been made out” and “if the testimony relates to prior invention and is from an interested party, as here, it must be corroborated.” Id. at 1316. So, instead of laying out a specific, required format for the content of all testimony regarding invalidity, as asserted by Patent Owner, this portion of Schumer confirms the unremarkable proposition that conclusory, overly general, confusing, and self-interested testimony should not be relied upon. Id.; see also Koito Mfg. Co., Ltd. v. Turn-Key-Tech, LLC, 381 F.3d 1142, 1152 (Fed. Cir. 2004) (“General and conclusory testimony, such as that provided by Dr. Kazmer in this case, does not suffice as substantial evidence of invalidity.”). Patent Owner does not show that the whole of Dr. Tamassia’s testimony suffers from any of these failings. Under 35 U.S.C. § 316(e), the preponderance of the evidence standard governs in determining whether Petitioner establishes unpatentability. We exercise discretion to determine the appropriate weight to accord the evidence presented, including expert opinions, based on the underlying facts supporting the opinion. We accord relevant portions of Dr. Tamassia’s testimony the appropriate weight based on that particular testimony and supporting evidence.” slip op. at 14

      “usage, could encompass motorcycles. Tr. 41:12–23. Patent Owner further concedes that the ’034 patent does not contain an express lexicographic definition of the term “vehicle,” (Tr. 41:24–43:8), and instead argues that “the disclosure of the patent in the claims and the problem to be solved” make clear that the term “vehicle” excludes motorcycles (id. at 42:19–43:5). Patent Owner, however, does not sufficiently identify the portions of the specification that allegedly support its claim construction argument. See PO Resp. 6–7 (indicating that Patent Owner’s claim construction argument is based on “certain discussion throughout the specification of the ’034 patent, as noted throughout this Response”). Patent Owner cites to Paragraph 38 of the Katona Declaration (see PO Resp. 7), but this declaration testimony relates to the Kato reference and does not identify any portion of the ’034 patent that supports Patent Owner’s argument (see Ex. 2002 ¶ 38; Ex. 1007 ¶¶ 4–5). Moreover, we find that the “Claim Interpretation” section of the Katona Declaration is conclusory in nature because it does not identify any specific portion of the ’034 patent specification that supports Patent Owner’s argument. See Ex. 1002 ¶ 44. For the foregoing reasons, and based on the current record and our review of the specification of the ’034 patent, we are not persuaded that the intrinsic record contains a lexicographic definition or a disclaimer that would exclude motorcycles from the scope of the term “vehicle.” To the contrary, the specification makes clear that the term ”vehicle” is a broad term that is intended to encompass any type of vehicle. Accordingly, we determine that the term “vehicle,” as used in the specification and claims of the ’034 patent, encompasses motorcycles.” slip op. at 10

      “directed to different fields of endeavor, depends on its argument that the term “vehicle,” as used in the ’034 patent, excludes motorcycles. As discussed above, we reject this argument. In view of our determination that the ’034 patent’s use of the term “vehicle” does not exclude motorcycles, we are persuaded by Petitioner’s arguments (see Reply 7–8; Ex. 1037 ¶ 23) and find that Kato is directed to the same field of endeavor as the ’034 patent, i.e., automatic directional control systems for vehicle headlights. Compare Ex. 1001, 1:57–67, with Ex. 1007 ¶ 1. Even if the ’034 patent’s controller and Kato’s motorcycle controller were directed to different fields of endeavor, Kato’s controller would still be reasonably pertinent to the problem addressed by the ’034 patent. In particular, we find that Patent Owner is incorrect in its assertion that “[n]o crossover applicability exists [] between control devices for a motorcycle headlight and those of four-wheeled vehicles.” PO Resp. at 19. For example, Kato’s controller adjusts a headlight’s optical axis based upon changes to pitch angle or steering angle of a motorcycle. Ex. 1007 ¶ 11; see Ex. 1037 ¶ 33. The controller of the ’034 patent adjusts the aiming angle of vehicle headlights to account for operating conditions such as “steering angle” and “pitch.” Ex. 1001, 2:3–20. In view of the fact that the ’034 patent and Kato both disclose controllers that automatically adjust headlights of motorized vehicles according to steering angle and pitch, we are persuaded by Petitioner’s arguments (see Reply 8–13; Ex. 1037 ¶¶ 24–29) that Kato would “logically have commended itself” to the attention of an inventor considering the problem addressed by the ’034 patent, even if the problem addressed by the ’034 patent only related to four wheeled vehicles.

Kato’s stated “Object of the Invention” is “to provide a headlight optical axis control device that can stably ensure a beam irradiation range of a headlight even when pitch, bank, steering angle or the like change while driving a motorcycle.” Ex. 1007 ¶ 6. Kato does disclose an embodiment that is able to correct direction of a headlamp “immediately” (id. ¶ 8), but we do not find that the portions of Kato cited by Patent Owner “criticize, discredit, or otherwise discourage investigation” into the use of a threshold of the type taught by Takahashi.

In step one of the Alice analysis, to determine whether the challenged claims are directed to an abstract idea, the inquiry is to ask, considered in light of the Specification, whether “their character as a whole” is directed to an abstract idea, not, as Patent Owner contends, identifying the “core invention” of the patent.

Relying on the distinction made in Alice between, on one hand, computer-functionality improvements and, on the other, uses of existing computers as tools in aid of processes focused on “abstract ideas,” the court in Enfish clarified that a relevant inquiry in step one of the Alice framework is to ask whether the “focus” of the claims is on the specific asserted improvement in computer capabilities or, instead, on a process that qualifies as an “abstract idea” for which computers are invoked merely as a tool.

We, therefore, find that substantially the same prior art was previously presented to the Office. We also find that substantially the same arguments were previously presented to the Office, including to the Board.

Finally, Petitioner argues that it has submitted “ample evidence” that the compounds of claims 1 and 2 would be the intended and expected result of combining the asserted references, and that claims 3–6 would not be an unexpected result of the suggested combination.

But Petitioner’s cited evidence relates to how a person of ordinary skill in the art would have considered separating and studying the stereoisomers of compound 84 to be ordinary and routine. See, e.g., Ex. 1050 ¶ 73 (“A POSITA at the time would have had an expectation that this stereochemical resolution could be easily achieved using known and commercially available techniques, without undue experimentation.”); Ex. 1052 ¶ 93 (“[I]t is my opinion that a POSITA at the time of the ’040 Patent’s priority date, would have been motivated to carry out standard new-drug investigation on each of the purified stereochemical forms in order to determine the effectiveness of each stereochemical form, to determine whether the drug could be administered as a racemic mixture or whether a purified enantiomer was required, to determine the interactions between stereoisomers if administered together, and to determine the effective amounts of each compound necessary for treatment of hypertension.”). The Board, however, assumed examiner established a prima facie case of obviousness. Ex. 1002, 199. Nevertheless, the Board still found the unexpected results evidence presented by the applicants to be sufficient. Finally, although the prior panel expressly set forth the deficiencies in the examiner’s position with respect to the evidence of unexpected results, the Petition is silent as to those deficiencies. In particular, Petitioner has not offered sufficient evidence to show why an ordinary artisan “would have expected the RSSS stereoisomer to have such [potentiating] properties” or to show “that the potentiating property, described in the declaration, is insignificant.” See Ex. 1002, 200. Because Petitioner has not addressed these issues, we are not inclined to reconsider the Board’s prior decision.

We recognize that the specification, in one instance, refers to zones with “different concentration levels of gas laden sterilant (e.g., hydrogen peroxide in air).” Ex. 1001, 9:51–53. The specification, however, refers elsewhere to the “residual concentration” of H2O2, measured in terms of ppm.

However, insofar as it is undisputed that “residual” sterilant concentrations on the bottle surface are disclosed in the specification and encompassed by the claim scope, Patent Owner does not explain why the skilled artisan would have understood such a concentration would be measured as parts of sterilant per million parts of carrier gas (i.e., airborne) as opposed to parts of sterilant per million parts of distilled water in accordance with the FDA Regulations. See Ex. 1013, 326 (“No use of hydrogen peroxide solution in the sterilization of food packaging material shall be considered to be in compliance if more than 0.5 part per million of hydrogen peroxide can be determined in distilled water packaged under production conditions.”). In short, neither the claims nor the specification limit how or where within “the plurality of zones” the sterilant concentration levels should be assessed in order to determine whether the 5 to 1 ratio is satisfied. As such, we find no basis to limit the claimed sterilant concentration levels to only airborne concentrations.” slip op. at 13

      “14 Petitioner asserts that a person of ordinary skill in the art (“POSITA”) would possess “an undergraduate scientific or engineering degree in a relevant field (such as microbiology or mechanical, packaging, process, or food engineering), at least five years of experience in an aseptic packaging and/or processing field (or a graduate degree conferring similar expertise), and an understanding of the relevant principles of microbiology and food science and technology.” Pet. 12; Ex. 1004, ¶ 12. Patent Owner has not contested that definition in its Patent Owner Response, but its expert Dr. Sharon asserts that Petitioner’s definition is only partially correct insofar as it does not recognize that the POSITA could have a mechanical engineering Patent Owner’s arguments are directed primarily to the sterilant concentration ratio requirement recited in each of the challenged independent claims 1, 4, 17, and 33. Specifically, the challenged claims all require that the sterilant concentration levels in the plurality of zones within the sterilization tunnel “are maintained at a ratio of at least about 5 to 1.” Accordingly, we focus on that limitation, and treat the claims together for purpose of our analysis. 1. Scholle in view of Chambers, the FDA Regulations, Biewendt, Kelbrick, Elliott, Akai, and Kodera Petitioner asserts that, using partitions and pressure differentials, the apparatus of Scholle (Ex. 1004) is configured to prevent the H2O2 sterilant from migrating from the sterilizing compartment to the drying and filling compartments, and, thus, the sterilant concentration in the sterilization compartment of Scholle is necessarily different from the concentration in the drying and filling compartments. Pet. 20 (citing Ex. 1004 ¶ 55; Ex. 1005, 6:36–41). Petitioner also points to Scholle’s teaching of using a 30% solution of H2O2 in water (i.e., 300,000 ppm) as a sterilant (id. at 21 (citing Ex. 1004 ¶ 56; Ex. 1005, 5:18–22)), and asserts that the skilled artisan “would understand that to ensure consistent sterilization and residual peroxide levels, the concentration of applied sterilant must necessarily be ‘maintained.’” Id. degree.

      “A preponderance of the evidence supports the conclusion that the skilled artisan would have found it obvious to optimize the sterilant concentration levels within the different “zones” (i.e., compartments) of Scholle’s apparatus in such a manner. Several features of Scholle’s apparatus facilitate such an optimization. First, a 30-percent solution of H2O2 in water is atomized and continuously sprayed into the spraying compartment during operation. Ex. 1005, 5:18–26, 45–49. Second, the spraying zone is separated from other compartments by a partition with a narrow opening designed “to reduce the amount of [H2O2] mist passing through the opening.” Id. at 6:12-15. Third, in the drying compartment, the H2O2 is “evaporated” and vented out of the sterile tunnel. Id. at 6:33-36, 44- 55. And finally, the sterile air maintains a positive pressure in the filling and drying compartments, thus reducing any tendency of the H2O2 mist in the spray compartment to migrate through the narrow opening into those other compartments. Id. at 5:36–43, 6:36-41. Although the parties dispute the particular concentration of H2O2 that exists in the sterilization tunnel after it is sprayed, there is no dispute that the spraying compartment in Scholle’s apparatus will have a higher sterilant concentration than the filling compartment. Indeed, even if airborne concentration levels were to be considered, Patent Owner’s counsel acknowledged during oral argument that “there is going to be more sterilant in the air in the spray zone than in the fill zone.” Tr. 122:12–14; see also Ex. 1035, 122:21–123:3 (Patent Owner’s expert Dr. Sharon conceding that the airborne concentration is lower in the fill zone than in the spray zone). Furthermore, we find that the concentration of the 30% solution of H2O2 will remain close to 300,000 ppm in the liquid phase at some point after it is sprayed into the spraying compartment. Scholle discloses that the spray heads atomize the H2O2 solution into a “fine mist or fog,” which coats the exterior of the containers to kill microorganisms. Ex. 1005, 5:22–23, 8:8–13. Although Dr. Sharon asserts that the skilled artisan “would be motivated to use as little sterilant in the sterilization zone as necessary to get the job done” (Ex. 2056, ¶24), he nonetheless acknowledged that, after condensation, the concentration of liquid H2O2 that coats the containers is “somewhere in the neighborhood” of 30%, or 300,000 ppm. Ex. 1035, Tr. 105:17–106:15. Here, we also credit Dr. Heldman’s testimony who stated that although the process of atomizing H2O2 may “result in varying concentrations,” the skilled artisan nonetheless “would understand that to ensure consistent sterilization and residual peroxide levels, the concentration of applied sterilant must necessarily be ‘maintained.’” Ex. 1004 ¶¶ 51, 56.” slip op. at 22
