The Board canceled claims 1–20 and denied substitution of claims 21–30 because the proposed claims lacked written-description support and were not shown patentable over prior art.

“2. Written Description Support Patent Owner bears the burden to show written description support in the original disclosure for each proposed substitute claim. 37 C.F.R. § 42.121(b)(1); 37 C.F.R. § 42.20(c). The test for written description support is “whether the disclosure of the application relied upon reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010).” slip op. at 8

“Dr. Sughrue testifies that one of ordinary skill in the art would have understood that the “different reactor configurations and catalysts” used in Jakkula “could and would lead to differing optimal temperatures from those reported in Craig.” Ex. 1040 ¶ 36 (emphasis added). For example, Dr. Sughrue testifies that one of ordinary skill in the art would have understood that reduced temperatures, as well as dilution—which was used in Jakkula but was not studied as an operating variable in Craig—could “greatly reduce the rate of dimerization and oligomerization of free fatty acids” and would lead to lower levels of high molecular weight hydrocarbons. Ex. 1040 ¶¶ 42, 60, 90; Ex. 1013, 4:11–13. Dr. Sughrue also provides evidence that in the years after the publication of Craig “the activity of hydroprocessing catalysts increased dramatically,” permitting lower reaction temperatures in the HDO step. Id. ¶¶ 31, 33. In light of these differences, Dr. Sughrue concludes that one of ordinary skill in the art “would not have been dissuaded from considering HDO reaction temperatures at or near the low end of the preferred temperature range taught in [Jakkula], e.g., 300 °C, or even lower temperatures within the more broadly taught range of 200-500 °C.” Ex. 1040 ¶ 37. We find Dr. Sughrue’s testimony persuasive. In particular, in light of Jakkula’s disclosed successful results, we are persuaded that one of ordinary skill in the art would not have viewed Craig’s 350 °C minimum temperature for “trouble-free operation” as a line not to be crossed, but would have understood that the optimal and minimum temperatures for the HDO step would vary depending on the particular reactor configuration and operating conditions used. See In re Boesch, 617 F.2d 272, 276 (CCPA 1980) (“Discovery of an optimum value of a results effective variable in a known process is ordinarily within the skill in the art.”). Although Dr. Klein presents an opposing view from that of Dr. Sughrue, upon review of both expert declarations and their corresponding depositions, on balance, we find that Dr. Sughrue’s testimony more persuasively considers not only the express teachings of Craig and Jakkula, but also the timing of the two disclosures, the differences in reactor configuration and operating conditions, and the knowledge, skill, and reasoning ability of one of ordinary skill in the art. Syntex (U.S.A.) LLC v. Apotex, Inc., 407 F.3d 1371, 1380 (Fed. Cir. 2005) (“What a reference teaches or suggests must be examined in the context of the knowledge, skill, and reasoning ability of a skilled artisan.”)” slip op. at 14

- Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayTeaching away not foundDecided for petitioner
“A reference may be said to teach away when a person of ordinary skill in the art, upon reading a reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). “[I]n weighing the suggestive power of each reference, [the Board] must consider the degree to which one reference might accurately discredit another.” In re Young, 927 F.2d 588, 591 (Fed. Cir. 1991). When two references do not use directly comparable techniques or operating conditions, the impact of an allegedly discrediting reference may be significantly reduced.
