Appeal No. 96-2520 Application 07/891,852 as taught by Sotome '124. However, every patent is presumed valid. 35 U.S.C. § 282. It is the burden of the Appellant to come forward with evidence, affidavits or declarations to rebut the presumption of operability of a patent by a preponderance of the evidence. In re Sasse, 629 F.2d 675, 681, 207 USPQ 107, 111 (CCPA 1980). We note that Appellant has not come forward with any evidence to support Appellant's argument and thereby Appellant has not met this burden of overcoming the Examiner's prima facie case. Therefore, we will sustain the Examiner's rejection of claim 4. In regard to the rejection of claim 5 under 35 U.S.C. § 102, Appellant argues on page 3 of the first reply brief that Sotome '124 fails to teach that the "peripheral ring portion is attached inside said support unit" as recited in claim 5. In the first supplemental answer, the Examiner argues that Sotome '124 teaches in Figure 5 that the peripheral ring portion is attached inside the support unit 19.
