      “II. STANDARD OF REVIEW The party challenging a decision in a request for rehearing bears the burden of showing the decision should be modified. 37 C.F.R. § 42.71(d) (2019). A request for rehearing “must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed.” 37 C.F.R. § 42.71(d). When rehearing a decision on a petition, the decision will be reviewed for an abuse of discretion. 37 C.F.R. § 42.71(c).” slip op. at 2

      “Petitioner also provides a reason why a person of ordinary skill in the art would have used [Baalmann’s] outer-wall configuration with a 1 m3 chamber such that the plasma zone covers the full chamber volume: “because doing so would have maximized the effective chamber capacity at any given chamber size by allowing the reactive plasma to reach all substrate surfaces, even for large substrates or large batches of smaller substrates extending near the outer limits of the chamber.” Pet. 35; Ex. 1002 ¶ 125. Dec. 20–21. Patent Owner does not address this portion of the Decision or our citation to page 35 of the Petition in the section of its Rehearing Request asserting we incorrectly found the Petition asserts a ground of obviousness based on Baalmann alone. Req. Reh’g 7–11.5 These portions of the record, which address Petitioner’s evidence demonstrating a person of ordinary skill in the art would have had reason to use a particular reactor configuration and plasma zone size, undermine Patent Owner’s assertion that “Petitioner’s obviousness theory fails to provide any reasoning why a POSA would combine Baalmann’s separate and distinct teachings to arrive at the claimed” slip op. at 6

      “teaching away argument in the Decision, we will do so here. With regard to Patent Owner’s contention that “Baalmann teaches away from the claimed method because . . . Baalmann discloses applying a power of 2kW in its only example using a reactor large enough to potentially satisfy claim 1’s plasma zone volume requirement, which would result in a plasma power density well outside the claimed range” (Req. Reh’g 14), we note that a reference teaches away from a claimed invention if it “criticize[s], discredit[s], or otherwise discourage[s]” modifying the reference to arrive at the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Patent Owner does not direct us to any such evidence in Baalmann, and we will not “read into a reference a teaching away . . . where no such language exists.” DyStar Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1364 (Fed. Cir. 2006). Additionally, although the one example of a 1 m3 reactor in Baalmann involved using a power density that did not fall within the claimed range, for purposes of an obviousness analysis, we cannot ignore the broader disclosure of Baalmann regarding the use of power densities in the range of between 0.5 kW/m3 and 5kW/m3, which does overlap the claimed range. See In re Wesslau, 353 F.2d 238, 241 (CCPA 1965) (“It is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position, to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one of ordinary skill in the art.”).” slip op. at 10

    • Strike new argumentNew argument disregardedDecided for petitioner

      “Req. Reh’g 14. Patent Owner cites to pages 54–56 of the Preliminary Response as the source for this argument and evidence. Although these pages do provide a discussion of the use of certain power densities in prior art references, this portion of the Preliminary Response primarily addresses Patent Owner’s arguments regarding whether a person of ordinary skill in the art “would have had a reasonable expectation of success when combining the disparate process of Coulson and Baalmann,” not what a person of ordinary skill in the art would have been “motivated” to do. Prelim. Resp. 56; see Par Pharmaceutical v. Twi Pharmaceuticals, Inc., 773 F.3d 1186, 1196 (Fed. Cir. 2014) (noting the proper analysis under § 103 requires “consideration of two factors: (1) whether the prior art would have suggested to those of ordinary skill in the art that they should make the claimed composition or device, or carry out the claimed process; and (2) whether the prior art would also have revealed that in so making or carrying out, those of ordinary skill would have a reasonable expectation of success”) (quoting Medichem, S.A. v. Rolabo S.L., 437 F.3d 1157, 1164 (Fed. Cir. 2006). As such, Patent Owner appears to present a new argument for the first time in the Rehearing Request. Not only is such an argument improper (see 37 C.F.R. § 42.71(d)), but the fact that it was raised for the first time in the rehearing means it is not something we could have overlooked. Even if Patent Owner had presented this “motivation” argument in the Preliminary Response, we remain unpersuaded of any error in our Decision. Patent Owner fails to explain sufficiently why a person of ordinary skill in the art would look to other prior art references for guidance regarding the use of a particular power density in large scale reactors in view of our determination that Baalmann itself discloses the use of a power density in the claimed range in a large scale reactor.” slip op. at 11

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “In light of the complete record now before us, we adopt Petitioner’s definition of one of ordinary skill in the art. In addition to the academic requirements associated with obtaining a bachelor’s degree in chemistry or chemical engineering, Petitioner’s definition includes at least two years of experience specific to chemical formulations used in the agricultural industry. Pet. 8. Patent Owner’s “definition” is generic to “formulation chemistry.” Sur-Reply 4. Patent Owner does not explain, nor do we discern, why the skilled artisan would not have had at least some work experience in developing chemical formulations in the relevant field, i.e., the agrochemical industry. Indeed, some of Patent Owner’s arguments are directed to solvent delivery systems used in the agricultural market. PO Resp. 57–78.” slip op. at 7

      “filing date, we apply the claim construction standard articulated in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). Under Phillips, claim terms are afforded “their ordinary and customary meaning.” Id. at 1312. “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Id. at 1313. Only terms that are in controversy need to be construed, and then only to the extent necessary to resolve the controversy. Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999). Neither party offers a construction for any claim term. Pet. 11; see also PO Resp., generally. On the complete record, we determine that no claim limitations need an express construction to resolve the controversy.” slip op. at 6

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

      “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”). Thus, on several bases, we find CN400 is analogous art to the ʼ108 patent and may be properly relied on in our obviousness determination.” slip op. at 24

      “Resp. 7–8. Patent Owner contends that “a POSITA is a person with a masters or doctorate degree in chemistry and/or chemical engineering, and having at least 3 years of experience working on the research, development, manufacture and formulations of HFC, HCFC and HFO compounds and mixtures.” Id. at 8 (citing Ex. 2003 ¶ 23). Patent Owner’s declarant Dr. Thrasher testifies, however, that he has “reviewed Dr. Sandford’s definition of a person of ordinary skill in the art” and his opinions “do not change under Dr. Sandford’s definition.” Ex. 2003 ¶ 24. We agree with the parties that a POSITA would have had an advanced degree in chemistry or chemical engineering, and experience in the research, development, and/or manufacture of hydrofluorocarbons (HFC) and hydrofluoroolefins (HFO), which is consistent with the level of ordinary skill in the art at the time of the invention as reflected in the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). Our determination regarding Petitioner’s challenge does not turn on the differences between Petitioner’s and Patent Owner’s definitions, and we note that our conclusions would be the same under either definition.” slip op. at 6

The ’709 patent states that the examples present a “general procedure [that] is illustrative of the method used for analyzing the products of fluorination reactions.” Ex. 1001, 12:30– 33. Examples 1, 2, and 3 of the ’709 patent use that procedure to measure the reaction product of (1) vapor phase dehydrofluorination of HFC-245eb to HFO-1234 with fluoride alumina catalyst, (2) pyrolysis of HFC-245eb, and (3) liquid phase dehydrofluorination of HFC-245eb to HFC-1234yf, respectively. Id. at 13:1–14:16. Although the ’709 patent provides the amounts of a number of different reaction products detected in each example, i.e., HFO-1234yf, HFO-1234ze, and HFC-245eb, notably absent is a measurement for 3,3,3-trifluoropropyne.

An experiment reproducing or recreating an example falls within the scope of that example so long as the reproduction is consistent with the teachings of the example, any deviations are immaterial, and the reasons for any deviations are adequately explained.
