Appeal No. 1997-1208 Application 08/077,219 difficulty ascertaining the scope of the invention recited in claims 1, 2, 4-7, 9-12, 14-17, 19, and 20. Therefore, the rejection of claims 1, 2, 4-7, 9-12, 14-17, 19, and 20 under the second paragraph of 35 U.S.C. § 112 is not sustained. The rejection of claims 1, 2, 4-7, 9-12, 14-17, 19, and 20 under 35 U.S.C. § 103 as being unpatentable over East. In rejecting claims under 35 U.S.C. § 103, it is incumbentupon the Examiner to establish a factual basis to support the legal conclusion of obviousness. See In re Fine, 837 F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988). In so doing, the Examiner is expected to make the factual determinations set forth in Graham v. John Deere Co., 383 U.S. 1,17, 148 USPQ 459, 467 (1966), and to provide a reason why one having ordinary skill in the pertinent art would have been led to modify the prior art or to combine prior art references to arrive at the claimed invention. Such reason must stem 10Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
