Appeal No. 96-2299 Application No. 08/072,753 As for the argument that the details of the bearing construction recited in claims 15, 16 and 18 would not have been obvious to the artisan, we note that Witt describes the pilot as “a ball-bearing pilot 29 which rolls against the unworked portion of the edge of the workpiece” (sentence bridging columns 2 and 3), and McKinney as a “ball bearing guide wheel 11 mounted . . . in a manner well known in the art” (column 3, lines 17-19). It is our opinion that the one of ordinary skill in the art would have recognized that ball bearing guide wheels conventionally comprise one piece inner and outer sleeves within which the ball bearings are mounted, and would have found it obvious to mount the guide wheels such that the inner sleeve is attached to the tool and the outer sleeve contacts the workpiece. It therefore is our conclusion that the teachings of the applied references establish a prima facie case of obviousness with regard to the subject matter of the appealed claims, and we therefore will sustain the rejection. The decision of the examiner is affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 8Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
