    “The claims at issue are apparatus claims rather than process claims. Accordingly, no specific means of achieving the interference fit is required. We construe “interference fit” as a structural limitation specifying the relationship of the bevel and frame. Even if construed as a product-by-process limitation (with the process being the insertion of a lens within a frame of lesser size), “determination of patentability is based on the product itself.” In re Thorpe, 777 F.2d 695, 697 (Fed. Cir. 1985). Patent Owner frames its proposed construction in terms of the process by which the fit comes about, but says little about the structural characteristics of the interference fit upon assembly. The Specification teaches that pressure upon the lens would lead to compression of the vertex. Ex. 1001, 4:40–55. That the vertex is in a compressed state is separately required in all claims by the “in compression” limitation. Id. at 8:54, 9:24. In view of the foregoing and in light of the parties’ arguments following institution, we modify our preliminary construction to recognize that an interference fit in this context implicates associated compressive forces. We, therefore, construe “interference fit” to mean “a relationship of the bevel of the lens and the receiving channel bottom of the eyeglass frame where such parts are in contact so as to exert frictional and compressive forces that secure the lens in place.”” slip op. at 17

    “Petitioner sets forth a rationale to combine the teachings of Gottschald and Schaeffer. Id. at 20. Petitioner argues that the teachings of Gottschald are applicable to the prescription lenses of Schaeffer as follows: POSITA would have been motivated by these teachings to use the method and device of Gottschald, with no change in its function, to edge the prescription plastic lens blank described by Schaeffer “so that the spectacle lens edge machining directly delivers a spectacle lens which is suitable for the selected spectacle frame, which has been ground to shape and which is provided with a bevel” (Gottschald, p. 6), and thereby to obtain the expected result of a “prescription plastic lens for use in an eyeglass frame” as recited in claim 1. Id. at 20. Patent Owner does not challenge the adequacy of Petitioner’s rationale with specificity. See PO Resp. 48–54. Rather, Patent Owner argues that Petitioner relies on “mere conclusory statements” throughout the Petition. Id. at 49. Such a generalized argument has little force. Having reviewed the evidence as a whole, we find that a person of ordinary skill in the art would have had reason to combine the teachings of Gottschald (regarding lens edging) and Schaeffer (regarding prescription lenses) in the manner Petitioner proposes.” slip op. at 28
