Appeal No. 2000-0504 Application 08/799,898 for the expression “fixedly positioned mounting means.” In view of the situation, wherein numerous claim terms lack antecedent basis, it is our opinion that no definite meaning can be ascribed to the claimed subject matter. When this is true of the terms in a claim, the subject matter of the claim cannot be considered obvious, but rather the claim should be rejected as indefinite. See In re Wilson 424 F.2d 1382, 1385, 165 USPQ 494, 496 (CCPA 1970). Since it is clear to us that considerable speculation and assumption are necessary to determine the metes and bounds of what is being claimed, and since a rejection under 35 U.S.C. § 103 cannot be based upon speculation and assumption, we are constrained to reverse the examiner’s rejection of claims 11 through 17. See In re Steele 305 F.2d 859, 862, 134 USPQ 292, 295 (CCPA 1962). It should be understood, however, that our reversal of the rejection under § 103 is not a reversal on the merits of the rejection but rather is a procedural reversal predicated upon the indefiniteness of the claimed subject matter. Accordingly, under the provision of 35 CFR 1.196(b) we enter this rejection of claims 11 through 17 under 35 U.S.C. § 112 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
