The Court of Customs and Patent Appeals did not adopt the position that is now urged by Kyocera. In In re Nathan, 328 F.2d 1005, 1008-09, 140 USPQ 601, 604 (CCPA 1964), the court held that the later-added limitation to the claims of the compound's alpha orientation was "an inherent characteristic" of the claimed subject matter, and reversed a new matter rejection. The Nathan court explained that "a subsequent clarification of or a change in an original disclosure does not necessarily make that original disclosure fatally defective." Id. at 1008, 140 USPQ at 603.
