The most pertinent of Bohannan’s fibers in this regard are those in the generally helically extending rovings 28 which form an angle of near 0° to near 90°, and usually between about 20° and 70°, with respect to a plane normal to the longitudinal axis. While both of these ranges fully encompass the significantly narrower 35° to 55° range set forth in the claim, they do not describe it with the specificity necessary to establish anticipation. At most, Bohannan presents a rebuttable prima facie case of obviousness here. See, e.g., In re Malagari, 499 F.2d 1297, 182 USPQ 549 (CCPA 1974) which notes, with implicit approval, “several cases wherein the prior art taught a broad range and the inventor was held entitled to claims limited to a narrow range within the 2 Similar arguments advanced by the appellants with respect to independent claims 12, 23 and 29 (see pages 6 through 8 in the brief) are likewise unconvincing. 6Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
