Appeal No. 96-1950 Application No. 08/099,929 are critical, see In re Woodruff, 919, F.2d 1575, 1578, 16 USPQ2d 1934, 1936-37 (Fed. Cir. 1990), and we consider that they have done so. The examiner argues that appellants have merely used routine skill to discover the optimum or workable range of thicknesses to produce a hose having flexibility, bendability and endurance to vibrations. However, we do not believe that appellants’ experimental data can be 5 characterized as the discovery of optimum ranges (In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955)), because there is no teaching in the prior art references (Igarashi ‘906 and Satoh) that the variables here involved, i.e., layer thickness and thickness ratios, are "known to be result effective." See In re Boesch, 617 F.2d 272, 276, 205 USPQ 215, 219 (CCPA 1980). In order for a claimed parameter to be deemed the result of obvious experimentation, any such experimentation must have come from within the teachings of the art. In re Waymouth, 499 F.2d 1273, 1276, 182 USPQ 290, 5The data in question are those contained in the Rule 132 Declaration of Tsutomu Kodama, filed April 11, 1994 (Paper No. 7). 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
