Appeal No. 96-0122 Application No. 08/096,581 performed without looking to appellant’s disclosure for the specific steps involved in the mathematical calculations. Thus, we will look to appellant’s disclosure for an understanding of the steps needed to solve the required calculations of claims 1, 2 and 5. When we turn to appellant’s disclosure for an4 understanding of the calculation steps, the meaning of the claimed calculations is no longer in doubt, and the claims 5 satisfy the provisions of the second paragraph of 35 U.S.C. § 112. The indefiniteness rejection of claims 1, 2 and 5 is reversed. The non-enablement rejection under the first paragraph Commission, 75 F.3d 1545, 1557, 37 USPQ2d 1609, 1617 (Fed. Cir.), cert.denied, 116 S.Ct. 2523 (1996). 4Keeping in mind that appellant has never relied on the provisions of the sixth paragraph of 35 U.S.C. § 112 or In re Donaldson, 16 F.3d 1189, 29 USPQ 1845 (Fed. Cir. 1994) to distinguish the claimed invention over any applied prior art. 5“When the meaning of claims is in doubt . . . they are properly declared invalid.” Amgen Inc. v. Chugai Pharmaceutical Co.
