His uncontradicted cross-examination supports a finding that one skilled in the art (1) knows the nature of the Pallflex filter and (2) would have been able to use the Pallflex filter in the diesel engine Otake environment. Opposing Dr. Farrauto’s testimony, all we have is an argument by counsel for Patent Owner. Paper 21, pages 8–9.

“3. Conclusion We hold that Petitioner has established by a preponderance of the evidence that the subject matter of claim 1 would have been obvious to a person having ordinary skill in the art. Patent Owner has not argued the separate patentability of dependent claims 5, 9, and 39. Accordingly, those claims fall with claim 1. We hold that Petitioner has not established by a preponderance of the evidence that the subject matter of claim 41 would have been obvious.” slip op. at 30

“The evidence supports a conclusion that the broadest reasonable interpretation of the term “moisture” is liquid water—that is, a condition of 100% relative humidity. The written description uses the term “moisture” in a context that suggests liquid water. See, e.g., Ex. 1001, 28:65-67 (applying a “wax/water slurry” to surface of sample film in order “to retain moisture”); 35:17-18 (applying heat to remove “moisture” from samples, suggesting removal of liquid water). Moreover, where the written description discusses water in vapor form, the inventors use the word “humidity” or “atmospheric moisture,” but not “moisture” alone. See, e.g., id. at 21:47 (referring to “atmospheric moisture”); 28:48, 60, 65 (referring to “humidity”). The ’189 patent further discloses that a “ribbon assembly can be buried under ground or water for long distance connections, such as between cities,” which is consistent with the proposition that an optical fiber coating must endure long periods of immersion in liquid water without delaminating. Ex. 1001, 67:43-45. In light of the context in which the term “moisture” appears in the specification, we conclude that the inventors used that term in its ordinary sense to refer to liquid water. The ’189 patent, thus, is directed to a coating composition that, after radiation cure, has sufficient adhesion to glass to prevent delamination in the presence of liquid water. We decline to resolve what temperature, or length of time of exposure to liquid water the coating must endure, without delaminating, in order to satisfy the claimed adhesion property. Resolving those conditions is not necessary to our analysis, which focuses on whether Corning’s wet adhesion test, conducted under conditions of 95% relative humidity, is probative of the extent to which a cured coating delaminates from glass when exposed to liquid water.” slip op. at 10

“We do not agree with Corning that the ’189 patent defines the term “stripping temperature” as “about 90°C to about 120°C.” Rather, the patent indicates that stripping temperature is “typically” within this range. Ex. 1001, 13:32-34; accord id. at 14:21-25 (“[F]or most coating compositions the design ribbon stripping temperatures are usually about 90° C. to about 120° C., but may be different depending on the specific design parameters for the particular coating composition.”). This disclosure is too imprecise to serve as a definition. See Paulsen, 30 F.3d at 1480. The ’189 patent does refer repeatedly, however, to 90°C as an exemplary stripping temperature. E.g., Ex. 1001, 31:14-15, 31:41-42, 50:55. The ’189 patent also identifies 100°C as an exemplary stripping temperature, particularly in the context of measuring change in length. Id. at 14:46-47, 18:44-45. Whatever other temperatures this term encompasses, it certainly encompasses at least the ones specifically identified. See Oatey Co. v. IPS Corp., 514 F.3d 1271, 1276 (Fed. Cir. 2008) (“We normally do not interpret claim terms in a way that excludes embodiments disclosed in the specification.”). The limitation requires no further construction.” slip op. at 11

“plots is whether they exhibit a linear region of negative slope. Corning argues that they do, and the description in Exhibit 2015 that a region of the Shustack Example I plot showing a “linear relationship” was used to calculate slope bears out this argument. See Ex. 2015, 1. DSM, in contrast, argues that Corning’s plots lack “a substantially smooth linear region” but offers little evidence to support this assertion beyond Dr. Taylor’s statements that the plots “have no linear region from which to measure a slope” and that they lack any “substantial linear region.” See Resp. 31; Ex. 2032 ¶ 86. Dr. Taylor gives no credible explanation for the basis on which he reaches these conclusions. Even if Dr. Taylor provided some underlying facts or data for this conclusion, Dr. Taylor’s statements do not support DSM’s argument that there is no substantially smooth linear region. As between the conflicting evidence on this point, we credit Corning’s evidence, particularly from Exhibit 2015, in which Corning’s Mr. Gleason identifies the region of linear relationship as extending between displacements of 2.76 mm and 7 mm. DSM does not explain why this determination is invalid. We agree with Corning that the plots for Shustack Example I show a linear region of negative slope from 2.76 mm to 7 mm. To be sure, the signal is noisy, and the plots are jagged, but that does not mean that a linear relationship is not discernible in that region.” slip op. at 23

“Corning’s proposed claim construction of “absorption maximum” as unreasonably broad in light of the Specification. Dec. 6. Based on the language in the Specification, the Board explained that [A]n absorption maximum does not include a “wavelength with the highest absorbance on either side of [the identified valley within the range of 240 and 360 nm]” unless that wavelength is also “a point on the curve wherein the tangent to the curve is parallel with the horizontal axis.” Id.

“patent under 35 U.S.C. § 102(e). Pet. 9. According to Corning, examples 8- 13 and a-d of Murphy meet all the limitations recited in claims 35, 39, 44, and 53-57, and thus, anticipate these claims. Id. at 40-46. DSM did not dispute that Murphy meets all the limitations recited in the challenged claims. Nor did it dispute that the effective filing date of Murphy is December 23, 1999. PO Resp. 41. Instead, it contended that Murphy could not qualify as § 102(e) prior art, because the inventors of the ’543 patent made the claimed invention through an actual reduction to practice before December 23, 1999. Id. at 41-55. As evidence, DSM submitted a “Rule 37 C.F.R. § 1.131 Declaration of Timothy E. Bishop,” one of the co-inventors of the ’543 patent. Ex. 2041. DSM also attached Exhibits A, B, and C to the Bishop Declaration as proof to antedate Murphy.4” slip op. at 5

“We find Corning’s arguments unconvincing. Nevertheless, we deny DSM’s Motion to Exclude. Similar to a district court in a bench trial, the Board, sitting as a non-jury tribunal with administrative expertise, is well-positioned to determine and assign appropriate weight to evidence presented. See, e.g., Donnelly Garment Co. v. NLRB, 123 F.2d 215, 224 (8th Cir. 1941) (“One who is capable of ruling accurately upon the admissibility of evidence is equally capable of sifting it accurately after it has been received . . . .”). Thus, in this inter partes review, the better course is to have a complete record of the evidence to facilitate public access as well as appellate review. See id. (“If the record on review contains not only all evidence which was clearly admissible, but also all evidence of doubtful admissibility, the court which is called upon to review the case can usually make an end of it, whereas if evidence was excluded which that court regards as having been admissible, a new trial or rehearing cannot be avoided.”).” slip op. at 19
