Appeal No. 1997-2660 Page 13
Application No. 08/224,407
Obviousness
A rejection under 35 U.S.C. 103 should not be based on
"speculations and assumptions." In re Steele, 305 F.2d 859,
862, 134 USPQ 292, 295 (CCPA 1962). "All words in a claim
must be considered in judging the patentability of that claim
against the prior art. If no reasonably definite meaning can
be ascribed to certain terms in the claim, the subject matter
does not become obvious-the claim becomes indefinite." In re
Wilson, 424 F.2d 1382, 1385, 165 USPQ 494, 496 (CCPA 1970).
