“Accordingly, the Director instructed us to “determine whether Petitioner has demonstrated that Figure 1 of Godefroy ‘is clear on its face’ or would have reasonably suggested the placement of Godefroy’s sacrificial anode ‘within 10 inches’ of the hot liquid inlet.” Id. at 9. “In making this determination,” the Director instructed us to “consider whether the expert testimony provides sufficient ‘technical detail, explanation, or statements supporting why the expert determines that the feature in question was required or would have been obvious based on the prior art disclosure.’” Id. In addition, although the Director’s decision “is limited to [our] application of Hockerson to the grounds in the Petition involving Godefroy,” the Director instructed us also to “consider what effect, if any, this decision has on the other asserted grounds.” Id. Finally, the Director instructed us to “set forth [our] interpretation” of “the limitation ‘within 10 inches of a hot liquid inlet to the radiator.’” Id. at 8 n.4.” slip op. at 4

“original decision, the Director’s decision, and the evidence currently of record, we determine that Petitioner has not shown a reasonable likelihood that it will prevail in showing that at least one of the challenged claims is unpatentable. Accordingly, we do not institute an inter partes review of any challenged claim based on any ground asserted in the Petition. IV. ORDER For the reasons given, it is: ORDERED that, pursuant to 35 U.S.C. § 314, the Petition is denied, and no inter partes review is instituted.” slip op. at 19
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner
“evidence. The challenged claims require that a sacrificial anode be placed within a certain distance—10 inches—of the hot liquid inlet, and, because the inlet has some non-zero size, it might be possible for an anode to be within that distance from some parts, but not from all parts, of the inlet. Accordingly, specifying the center axis of the inlet as the point from which to measure the distance to the anode improves on the plain words of the claim in terms of achieving the claim’s objective of placing the anode within a specified distance of the inlet. Moreover, when discussing the distance from the inlet to the anode, the specification of the ’494 patent uses the language “within 10 inches in any direction of the center axis of the inlet connection.” Ex. 1001, 7:61–64. Thus, the intrinsic evidence supports adopting Petitioner’s claim construction. Petitioner’s declarant, Dr. Medlin, relies on Petitioner’s proposed construction. See, e.g., Ex. 1004 ¶¶ 20 (noting that the construction “within 10 inches of the center axis of [a] hot liquid inlet” “ha[s] been adopted by Petitioner”), 96 (“the sacrificial anodes contained in each of the turbulators 2 would be placed within 10 inches of a center axis of a hot liquid inlet to the radiator of Tomosada”), 144 (“A POSITA would understand from Figure 1 that the sacrificial anode 14 is within 10 inches of a center axis of a hot liquid inlet”), 267 (“These teachings would further motivate a POSITA to located the sacrificial anode 12 within 10 inches of a center axis of the hot liquid inlet.”). This support for Petitioner’s proposed construction provides further reason for us to adopt it. Because it is supported by the intrinsic evidence of record, because Patent Owner proposes no alternative construction, and because Petitioner’s expert supports it, we adopt the construction of “within 10 inches of a hot liquid inlet to the radiator” that Petitioner proposes. Thus, we construe this term as “within 10 inches of the center axis of a hot liquid inlet to the radiator.” In other words, when discussing the distance between a hot liquid inlet and a sacrificial anode, we interpret “hot liquid inlet” as “center axis of the hot liquid inlet.”” slip op. at 5

“Inherency may be relied upon in arguing either anticipation or obviousness. Schering, 339 F.3d at 1377 (applying inherency in an anticipation context); Par Pharma. Inc. v. TWI Pharma., Inc., 773 F.3d 1186, 1195–96 (Fed. Cir. 2014) (applying inherency in an obviousness context). In both cases, however, “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” Therasense, Inc. v. Becton, Dickinson & Co., 593 F.3d 1325, 1332 (Fed. Cir. 2010). Instead, “the limitation at issue necessarily must be present, or the natural result of the combination of elements expressly disclosed by the prior art.” Par Pharma., 773 F.3d at 1195–96. Here, Petitioner has not shown sufficiently that, in Godefroy, the sacrificial anode necessarily is placed within 10 inches of the center axis of the hot liquid inlet. Dr. Medlin testifies that Figure 1 of Godefroy shows that “an entirety . . . or at least a significant portion of the sacrificial anode 14, is within 10 inches of a center axis of the inlet.” Ex. 1004 ¶ 144. But we cannot say that Figure 1 of Godefroy is clear on its face, or reasonably suggests, that this is necessarily the case. There are no dimensions shown on Figure 1, so it is unclear from the figure what the diameter of pipe 12 is. If that diameter is larger than 20 inches, then it simply is untrue that “sacrificial anode 14 is . . . necessarily placed within 10 inches of a center axis of a hot liquid inlet to the radiator,” as Dr. Medlin testifies. Id. ¶ 361. As noted above, neither Petitioner nor Dr. Medlin relies on the hot liquid inlet of Godefroy having any particular diameter, and Godefroy is silent as to the diameter of its inlet. Pet. 69–70; Ex. 1004 ¶¶ 144, 359–361, 381–382, 406–408; Ex. 1008, 1–15. Moreover, as Patent Owner notes, there is a wide range of sizes of radiators, including automobile radiators, available. Prelim. Resp. 3–5; Exs. 2001–2003. In the absence of any testimony or other evidence that tends to show that radiator inlet pipes necessarily have diameters less than 20 inches, Petitioner has not shown sufficiently that the diameter of Godefroy’s inlet pipe is small enough to ensure that any portion of the anode necessarily is within 10 inches of the center axis of the inlet.” slip op. at 11

“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.

“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.
