Appeal No. 1998-3101
Application 08/313,175
argument that it encompasses the amount used by the appellants
is mere speculation, and such speculation is not a sufficient
basis for a prima facie case of obviousness. See In re
Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967),
cert. denied, 389 U.S. 1057 (1968); In re Sporck, 301 F.2d
686, 690, 133 USPQ 360, 364 (CCPA 1962). We therefore reverse
the rejection under 35 U.S.C. § 103.
DECISION
The rejections of claims 1, 3 and 4 under 35 U.S.C.
§ 112, first and second paragraphs, and under 35 U.S.C.
§§ 102(b) and 103 over Snow, are reversed.
REVERSED
