Appeal No. 1998-3281 Application 08/650,500 appellant's claims reasonably may be said to embrace. See In re Wilson, 424 F.2d 1382, 1385, 165 USPQ 494, 496 (CCPA 1970) ("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."). Compare In re Steele, 305 F.2d 859, 862-63, 134 USPQ 292, 295 (CCPA 1962). Specifically, claim 22 defines a "polymer" selected from two groups of polymers defined by their formulae. The polymers denominated as group (a) include a backbone R defined solely as an "organic group" having two or more carbon atoms in the repeating unit. One substituent on the backbone is represented by the substituent C, the universally recognized symbol for carbon, although C in at least part of appellant's claim does not stand for carbon! Rather C is stated to be "a hydrophobic saturated alkyl group having at least about 6 carbon atoms bonded in a linear chain." The second substituent on the backbone is represented by the substituent B, the universally recognized symbol for boron, although B does not stand for boron in the appealed claims! Rather, B is stated to be a "hydrophilic groupPage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
