Appeal No. 1997-4234 Application No. 08/423,211 citing: Eiselstein v. Frank, 52 F.3d 1035, 1038, 34 USPQ2d 1467, 1470 (Fed. Cir. 1995). Thus, as we have stated above, all that is necessary to satisfy the description requirement of 35 U.S.C. § 112, first paragraph, is a written description of the presently claimed invention which would convey to those skilled in the art, that, as of the filing date the applicants were in possession of the invention. Vas-Cath Inc. v. Makurar, supra. The rejections under 35 U.S.C. § 102(e)/103 For reasons stated supra in our new ground of rejection under 37 CFR § 1.196(b), we are of the opinion that claims 1-27 and 29, fail to satisfy the requirements of 35 U.S.C. § 112, second paragraph. Since the metes and bounds of these claims are unclear, we do not reach the rejections under 35 U.S.C. § 102(e) or 35 U.S.C. § 103 as it relates to these claims. In making a patentability determination, “[a]nalysis begins with a key legal question -- what is the invention claimed?” since “[c]laim interpretation . . . will normally control the remainder of the decisional process,” Panduit Corp. v.

Where as here, a reasonable interpretation of the claim can not be made, if follows that it is impossible to compare the claimed invention with the prior art. See Graham v. John Deere Co., 383 U.S. 1,17, 148 USPQ 459, 467 (1966)("Under § 103, the scope and content of the prior art are to be determined; differences between the prior art and the claims at issue 11Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
