Appeal No. 96-1819 Application 08/112,151 of claims 8 and 10 under 35 U.S.C. § 112, first paragraph, and (3) enter new rejections of claims 8-10 under 35 U.S.C. § 112, second paragraph. Considering first the rejection of claims 8-10 under 35 U.S.C. § 103 based on the combined teachings of Marx and Choski, we have carefully considered the subject matter defined by these claims. However, for reasons stated infra in our new rejections entered under the provisions of 37 CFR § 1.196(b) no reasonably definite meaning can be ascribed to certain language appearing in the claims. In comparing the claimed subject matter with the applied prior art, it is apparent to us that considerable speculations and assumptions are necessary in order to determine what in fact is being claimed. Since a rejection on prior art cannot be based on speculations and assumptions (see In re Steele, 305 F.2d 859, 862-63, 134 USPQ 292, 295-96 (CCPA 1962) and In re Wilson, 424 F.2d 1382, 1385, 165 USPQ 494, 496 (CCPA 1970)), we are constrained to reverse the examiner's rejection of claims 8-10 under 35 U.S.C. § 103. We hasten to add that this is a procedural reversal rather than one based upon the merits of the § 103 rejection. 3Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
