Appeal No. 1997-3801 Application 08/397,960 such an explanation but, rather, has merely made an assertion that one of ordinary skill in the art would have determined the degree of fusing by routine experimentation. The motivation relied upon by the examiner for using only partial fusing comes solely from the description of appellant’s invention in the specification. Thus, the examiner used impermissible hindsight when rejecting the claims. See W.L. Gore & Associates v. Garlock, Inc., 721 F.2d 1540, 1553, 220 USPQ 303, 312-13 (Fed. Cir. 1983), cert. denied, 469 U.S. 851 (1984); In re Rothermel, 276 F.2d 393, 396, 125 USPQ 328, 331 (CCPA 1960). Accordingly, we reverse the examiner’s rejections.5 DECISION The rejections under 35 U.S.C. § 103 of claims 1, 2, 6-11 and 15 over Warther in view of Ohta, and claims 3-5 and 12-14 over Warther in view of Ohta and Biddle, are reversed. REVERSED 5 Biddle, which is applied by the examiner to dependent claims 3-5 and 12-14, is not relied upon for any teaching which would remedy the above-discussed deficiency in the disclosures of Warther and Ohta. 6Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
