      “The parties agree that a person of ordinary skill in the art in the field of the ’087 patent in June 20154 “would have had at least a bachelor’s degree in a field such as chemistry, physics, or chemical engineering, as well as at least two years of experience with plasma-polymerization techniques.” Pet. 20 (citing Ex. 1002 ¶¶ 22–29); PO Resp. 13 (Patent Owner stating that it “does not dispute this characterization of the level of ordinary skill in the art.”); see also PO Sur-reply 1–2 (noting both parties’ agreement on the education and experience level of the ordinarily skilled artisan).” slip op. at 7

      “Because of Patent Owner’s shifting definitions of the education and experience level of the ordinarily skilled artisan, it is unclear on the complete record what precise definition Patent Owner and Dr. Senkevitch are applying when arguing the skilled artisan’s capabilities. PO Resp. 13, 22–27, 31–32, 34–40; PO Sur-reply 1–6, 11–13; Ex. 2007 ¶¶ 30, 31, 33, 34, 37, 40, 52–55, 60, 68, 74, 76, 77, 80–86, 89, 91, 94, 95, 100, 102–105, 108, 110, 111, 113–116, 118–120, 122, 124, 127–134. We, therefore, give Dr. Senkevitch’s testimony regarding the capabilities of a person of ordinary skill in the art minimal weight, which leaves us with Patent Owner’s insufficiently supported arguments regarding the skilled artisan’s capabilities. PO Resp. 13, 22–27, 31–32, 34–40; PO Sur-reply 1–6, 11–13. Moreover, as Petitioner correctly points out, the ʼ087 patent expressly teaches that the precise conditions for forming a protective polymeric coating “will vary depending upon factors such as, without limitation, the nature of the monomer compound, the crosslinking agent, the substrate, as well as the desired properties of the coating” and that such “conditions can be determined using routine methods.” Ex. 1001 15:1–15:5 (emphasis added); Pet. Reply 17. Where the patent itself leaves to the judgment of an ordinarily skilled artisan the assessment of these factors to ascertain suitable conditions for forming the protective coating, we find persuasive Petitioner’s view that it would have been well within the level of ordinary skill to ascertain such suitable conditions.” slip op. at 20

    • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

      “We disagree with Patent Owner. Although the claims of the ʼ087 patent recite obtaining the protective cross-linked polymeric coating “by exposing the device or component to a plasma,” the field of endeavor analysis in an analogous art inquiry does not exclusively turn on the claims at issue, but rather takes account of the entirety of a patent’s disclosure. See In re Bigio, 381 F.3d 1320, 1326 (Fed. Cir. 2004) (explaining that “the PTO must show adequate support for its findings on the scope of the field of endeavor in the application’s written description and claims” (emphasis added)); In re Mettke, 570 F.3d 1356, 1359 (Fed. Cir. 2009) (rejecting an argument that the field of endeavor was limited to a claimed “Internet terminal” when “the specification describes various communication media, including facsimile machines and email, as related to the invention.”). This is significant here because the ʼ087 patent discloses that “[t]he … invention relates to protective coatings” and specifically “relates to protective coatings for electronic or electrical devices and components thereof, and methods of forming such coatings.” Ex. 1001, 1:14–17. Based on this disclosure, we find that the ʼ087 patent’s field of endeavor relates to “protective coatings for electronic or electrical devices and components thereof” broadly, not just those formed on such devices or components via a plasma polymerization process as asserted by Patent Owner. Id. Although Cohen does not explicitly disclose that its crosslinked polymers constitute a “protective coating,” Cohen does disclose that its “copolymerizable mixture can be cast into films” (Ex. 1004, 2:61–62), that the polymerization can “effected in situ,” and that the polymers may be used in “numerous” electrical applications (id. at 5:17–25). Tr. 8:9–10:2, 27:2– 21; see Pet. Reply 5 (explaining how “Cohen described insulating polymers that could be applied as films and be used to protect substrates including cables and electrical coils.” (citing Ex. 1004, 2:60–63, 5:13–25)). These disclosures suggest strongly that Cohen’s crosslinked polymers––if cast into a film or formed in situ on an electrical device or component––would serve as a protective coating on that electrical device or component, even though Cohen does not expressly refer to its crosslinked polymers ipsis verbis as a “protective coating.” Thus, we find that Cohen is within the field of endeavor of the ʼ087 patent.” slip op. at 15

      “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.

      “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

      “speech-recognition device” discussed supra, this limitation requires a “speech recognition device that recognizes spoken words without using predefined voice patterns.” A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious to a person of ordinary skill in the art at the time the invention was made. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). Obviousness is resolved based on underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). Petitioner bears the burden of proving unpatentability of the challenged claims, and the burden of persuasion never shifts to Patent Owner.

      “analogous art. PO Resp. 47; Sur-Reply 8, 15–16. Patent Owner incorrectly frames the analogous art inquiry by comparing whether the prior art references are analogous to each other. See PO Resp. 47 (“not all three references are in the same field of endeavor”); Sur-Reply 16 (asserting that CN400 “is not analogous art with Iannotta [] and/or Kolc” because CN400’s NBPT is purportedly “not dissolved in any solvent”). Our reviewing court has stated, however, that “[a] reference qualifies as prior art for a determination under § 103 when it is analogous to the claimed invention.” Innovention Toys, LLC v. MGA Entertainment, Inc., 637 F.3d 1314, 1322 (Fed. Cir. 2011) (citing In re Clay, 966 F.2d 656, 658 (Fed. Cir. 1992). Quoting In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004), the court stated Two separate tests define the scope of analogous art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed, and (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. Innovention Toys, 637 F.3d at 1322. Regarding whether the CN400 patent is in the same field of endeavor as the ʼ108 patent, we must consider the scope of the ʼ108 patent as a whole and not just the claims. In re Mettke, 570 F.3d 1356 (Fed. Cir. 2009) (rejecting appellant’s attempt to rely on the claimed subject matter to define the relevant “field of endeavor” when the specification described a broader one). Significantly, the ʼ108 patent discloses both solutions and suspensions of NBPT. See Ex. 1001, 5:20–52, 6:5–12, 6:39–40 (disclosing various solutions of NBPT), and 13:24–36 (setting forth an embodiment that formed “a suspension of NBPT in the aqueous mixture” that may “be solved by agitation”). Therefore, regardless of whether CN400’s process set forth in its claim 1 results in a solution or suspension of NBPT, CN400 is from the same field of endeavor as defined by the ʼ108 patent itself––“solvent formulations for the urease inhibitor . . . NBPT.” Ex. 1001, 1:15–18. Even if CN400 was not in the same field of endeavor as the ʼ108 patent, we find it is reasonably pertinent to the particular problem with which the inventor was involved. The ʼ108 patent identifies NBPT formulation toxicity as problematic to the environment, animals, and possibly humans (id. at 2:60–62, 4:8–33), and expressly states “it is desirable to develop formulations/fertilizers that are less toxic to the environment and to animals and humans” (id. at 4:34–36). The skilled artisan would have been aware of this toxicity problem with NBPT-containing formulations (Ex. 1025, 1; Ex. 1007 ¶ 6), and CN400 was also concerned with this problem (Ex. 1006, 1 (Abstract), ¶¶ 2, 5; see also Ex. 2006, 461 (machine translation of CN400 abstract noting how use of its fertilizer formulation will not pollute the environment), 462 ¶ 2, 463 ¶ 5. Notably, Patent Owner does not address this second test in its briefing. Tr. 39:6–11 (Patent Owner’s counsel acknowledging “[w]e did not address the other prong in the briefing”).

      “II. THE REQUEST FOR REHEARING In pertinent part, 37 C.F.R. § 42.71(d) states: The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. Thus, a request for rehearing is not an opportunity merely to disagree with the Board’s assessment of the arguments or weighing of the evidence, or to present new arguments or evidence.” slip op. at 2

      “held cake decorator extruder” as “a three-dimensional (3D) drawing device” in the ʼ444 patent’s Notice of Allowance. Req. 4; Ex. 1002, 344. When viewed in context, however, we do not share Petitioner’s view that the Examiner’s mere characterization of Young’s extruder as a three-dimensional (3D) drawing device, on its own, rises to the level of a “rejection” of Patent Owner’s arguments distinguishing 3D drawing devices from devices that deposit material in layers over time. Ex. 1002, 317–322.2 In fact, the Examiner provides no discussion whatsoever regarding the “three-dimensional” aspect of Young’s device in the Notice of Allowance, but rather focuses on Young’s internal actuators, motor, and gear train. Id. at 344. Thus, the Examiner’s isolated statement that Young’s device is a three-dimensional (3D) drawing device, without more, is not enough to 2 We disagree with Petitioner’s contention (Req. 5) that Patent Owner’s statements made during prosecution were not sufficiently “clear and unmistakable” to invoke the doctrine of prosecution disclaimer. Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1325–26 (Fed. Cir. 2003); see also Spectrum Int’l, Inc. v. Sterilite Corp., 164 F.3d 1372, 1378–79 (Fed. Cir. 1998) (explaining how “explicit statements made by a patent applicant during prosecution to distinguish a claimed invention over prior art may serve to narrow the scope of a claim” because “[b]y distinguishing the claimed invention over the prior art, an applicant is indicating what the claims do not cover.”). persuade us that the Examiner was unequivocally rejecting Patent Owner’s construction of “a three-dimensional (3D) drawing device.”” slip op. at 6

      “Thus, Petitioner’s Request raises new arguments that could have been raised in its Petition. Specifically, the prosecution histories of both the ʼ444 patent and the ʼ266 application provided ample notice to Petitioner of Patent Owner’s previous claim construction positions. Petitioner could have presented a countervailing claim construction argument in its Petition, but instead raises new arguments here in its Request. These new arguments fail the standard set forth in Rule 42.71(d) at the outset because the Board cannot overlook or misapprehend an argument that was not before it. Nevertheless, we determine that even if these arguments were timely made in the Petition or in a Board-authorized Reply, they do not persuade us that the claim construction for the phrase “three-dimensional (3D) drawing device” as set forth in our Decision was erroneous.
