Appeal No. 2000-1315 Application 09/152,563 provide Famolare’s selectable traction area with a reduced thickness as recited in claim 15. The Aulby affidavit is entitled to little, if any, probative value as evidence of non-obviousness here since the benefits alleged in the affidavit are afforded by a bowling shoe tip which is not part of the shoe recited in claim 15. Accordingly, we shall sustain the standing 35 U.S.C. § 103(a) rejection of claim 15 as being unpatentable over Famolare in view of Bauer, McCord, Leclercq and Trentin. We shall not sustain, however, the standing 35 U.S.C. § 103(a) rejection of claims 12 and 13, which depend from claim 10, as being unpatentable over Famolare in view of Bauer, or the standing 35 U.S.C. § 103(a) rejection of claim 14, which depends from claim 10, as being unpatentable over Famolare in view of Bauer, Ludwig, Gillet and Guarrera. For the reasons expressed below, the scope of these claims is unclear. As a consequence, the standing prior art rejections thereof must fall because they are necessarily based on speculative assumption as to the meaning of the claims. See In re Steele, 305 F.2d 859, 862-63, 134 USPQ 292, 295 (CCPA 1962). It should be understood, however, that our decision in 11Page: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: November 3, 2007
