Appeal No. 98-0683 Application 08/505,853 rear view mirror with an attaching means is an "obvious expedient," we must point out that obviousness under § 103 is a legal conclusion based on factual evidence. In re Fine, 837 F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988). The mere fact that Short attaches the auxiliary sun visor in "close proximity" to the front face of the rear view mirror (i.e., on the supporting arm or stud 15) does not serve as a sufficient factual basis for establishing the obviousness of providing an attaching means that substantially covers the entire front face of the rear view mirror as claimed. See In re GPAC, Inc., 57 F.3d 1573, 1582, 35 USPQ2d 1116, 1123 (Fed. Cir. 1995) and In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968). With respect to claim 9, we have carefully reviewed the teachings of Viertel but find nothing therein which would overcome the deficiencies of Short, Lystad, Gleason and Hou that we have noted above. The rejections of claims 1-11 under 35 U.S.C. § 103(a) are reversed. REVERSED 6Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
