Appeal No. 1996-2966 Application No. 08/257,232 claimed invention. The legal standard for definiteness is whether a claim reasonably apprises those of ordinary skill in the art of its scope. In re Warmerdam, 33 F.3d 1354, 1361, 31 USPQ2d 1754, 1759 (Fed. Cir. 1994). We are unable to ascertain the scope of the invention as set forth in claims 1 and 11 in view of the failure of the claims to establish a meaning for the resetting step. Since the scope of these claims is not clear, a rejection of independent claims 1 and 11 under the second paragraph of 35 U.S.C. § 112 is appropriate.

We now consider the examiner’s rejections of the claims under 35 U.S.C. § 103.

In re Steele, 305 F.2d 859, 862-63, 134 USPQ 292, 295 (CCPA 1962). Since we have just determined that the scope of the claimed invention is indefinite and subject to conjecture, a 5Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
