Unexpected Results Irrelevant to 102 Rejections
Note:
Evidence of unexpected results cannot overcome a rejection under 35 U.S.C. 102 based on prior art.

Evidence of secondary considerations, such as unexpected results or commercial success, is irrelevant to 35 U.S.C. 102 rejections and thus cannot overcome a rejection so based. In re Wiggins, 488 F.2d 538, 543, 179 USPQ 421, 425 (CCPA 1973).
