“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard.

“After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims. As we explain in Section III(G), infra, Petitioner’s challenges to the ’227 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak. Given the strength of Petitioner’s challenges on the present record, this is not a situation where we would say that “reasonable minds can disagree regarding the purported treatment of the art,” and we therefore determine that the Examiner erred by not considering the art in substantially the combination Petitioner proposes. Where Patent Owner states that “evidence that the Examiner did not consider these references in combination” is lacking (PO Sur-Reply 5), we disagree. If the Examiner considered these references in combination, the Examiner would have, given the apparent strength of Petitioner’s position on the merits on this record, issued a rejection.

CONCLUSION For the reasons above, we determine that the information presented in the Petition establishes that there is a reasonable likelihood that Petitioner would prevail with respect to challenged claims 1–30 of the ’602 patent. At this juncture in the proceeding, we have not made a final determination with respect to the patentability of the challenged claims, or with respect to claim construction. V. ORDER For the foregoing reasons, it is ORDERED that pursuant to 35 U.S.C. § 314(a), an inter partes review of claims 1–30 of the ’602 patent is hereby instituted with respect to all grounds of unpatentability set forth in the Petition; and” slip op. at 36

“Petitioner, in the Petition, proposes that a person of ordinary skill in the art “would have at least a bachelor’s degree in Polymer Science and Engineering, Material Science and Engineering, or a related engineering field, combined with at least three years of experience in the formulation, manufacturing, and end-use performance of polymeric film and sheet products.” Pet. 3 (citing Ex. 1003 ¶ 23).

“The Board regularly denies as moot motions to exclude evidence that is not relied upon in a final written decision. See, e.g., Foursquare Labs, Inc., v.

Patent Owner does not persuade us that a deviation from this general practice is warranted in this case––the reason given by Patent Owner, involving concerns stemming from appellate review, would apply to all cases. We do not rely on Exhibit 1047–1049, 1051, 1060, 1061, 1070, or 1071 in this decision, therefore, we deny Patent Owner’s Motion to Exclude as moot. B. Petitioner’s Motion to Exclude Exhibit 2001 (Paper 52) Petitioner moves to exclude paragraphs 13–25, 29–40, 42–43, 48–49, 56–61, and 66–75 of Exhibit 2001, which is the declaration of Dr. Brant. Paper 52. In Petitioner’s view, Dr. Brant’s “declaration is replete with inadmissible hearsay, improper legal conclusions, and testimony unsupported by reliable methods or personal knowledge.” Id. at 1. made available for cross-examination pursuant to routine discovery in our forum. Petitioner’s objections otherwise go primarily to the weight that should be accorded to Dr. Brant’s testimony, without raising any persuasive arguments for its exclusion. See generally id. (Petitioner’s arguments). Accordingly, we deny Petitioner’s Motion to Exclude Exhibit 2001. C. Petitioner’s Motion to Exclude Exhibit 2003 (Paper 53) Petitioner moves to exclude certain paragraphs of Exhibit 2003, which is the declaration of Dr. Schleicher, a named co-inventor of the ’882 patent. Paper 53. We do not rely on Dr. Schleicher’s declaration in this decision. Accordingly, we deny Petitioner’s Motion to Exclude Exhibit 2003 as moot. D. Petitioner’s Motion to Exclude Exhibit 2004 (Paper 54) Petitioner moves to exclude paragraphs 6–59 of Exhibit 2004, which is the declaration of Dr. Boutrid, another named co-inventor of the ’882 patent. Paper 54. In Petitioner’s view, Dr. Boutrid’s declaration “is riddled with inadmissible evidence, including hearsay, double hearsay, and testimony lacking personal knowledge. Much of the declaration relies on out-of-court statements from unidentified customers and unidentified UV-curable resin manufacturers, none of whom are identified or made available for examination.” Id. at 1. Much of the testimony about which Petitioner’s objects pertains to customer complaints about Patent Owner’s products, and whether maleic anhydride was included in the curable resin used by the customers, which form no part of this decision. See, e.g., id. at 4–7. We can take account of Petitioner’s objections, including Petitioner’s view that parts of Dr. Boutrid’s testimony are based on impermissible hearsay and unsound the record for appeal.

“We agree with Patent Owner that Petitioner relies on a list of optional additives set forth in Hummel––a list that Hummel provides without any guidance as to why any particular additive would have been selected to serve any purpose, specifically in relation to the relevant layer (e). See Ex. 1005, 11:18–26 (relevant disclosure in Hummel). In other words, Hummel’s disclosure does not teach, with anticipatory specificity, a multilayer film in which a migrating compound is selected specifically for addition to layer (e).

Reply 3. the particular problem with which the inventor is involved.” In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992). Schuhmann’s release films are “reasonably pertinent” to a problem addressed in the ’882 patent, namely, providing a “release effect against adhesive substances such as resins.” Ex. 1001, 2:56– 57. So too is Hummel, which relates to removal of an inner tubular layer, “after the resin has cured,” without “tearing or seizing” during the process of removal. Ex. 1005, 7, 23.
