Appeal No. 1998-3398 Application No. 08/634,515 see no reason why this optimization function would not meet the claim limitation of augmenting mathematical functions, as broadly recited in the claim, particularly as no arguments have been presented to convince us otherwise. Therefore, Hayashi appears to meet all of the limitations of claim 12, with Cocke and either Morgan or Rall merely being cumulative. Although the rejection is based on a combination of references, it is permissible to affirm the rejection relying on only one. See In re Bush, 296 F.2d 491, 496, 131 USPQ 263, 266-67 (CCPA 1961). Accordingly, we will affirm the rejections of claim 12 and its dependents, claims 13 through 18. CONCLUSION The decision of the examiner rejecting claims 1 through 18 under 35 U.S.C. § 103 is reversed as to claims 1 through 11 and affirmed as to claims 12 through 18. 7Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
