Appeal No. 96-3643 Application No. 29/008,022 design expedient to one of ordinary skill in the art. The Bell catalog page also discloses various tennis rackets with varying throat widths which shows that this change in size is obvious. Appellant asserts that the “Bell racket head is smaller and has a larger aspect ratio (length/width) and the shaft is longer in comparison with the claimed design. Also, the shaft and head frame portions are thinner in the claimed design than the frame of the Bell racket “C”.”. Again these differences are minor changes in proportions or sizes and are not seen to be patentable advances in the racket art. In re Stevens, [173 F.2d 1015,] 81 USPQ 362 [(CCPA 1949)], was cited to support the Examiner’s contention that changes in proportions was obvious and not a basis for patentability. [Answer, pages 4 and 5.] From the above it is readily apparent that the examiner recognizes that significant differences exist between the claimed design and that of tennis racquet “C” of the Bell Catalog but, nevertheless, seeks to dismiss such differences as changes in proportion that are “obvious and not a basis for patentability,” citing Stevens as authority. To the extent that the examiner is attempting to extract from Stevens a hard and fast rule that all changes in proportion are per se unpatentable advances, we are of the opinion that the examiner’s reliance upon this authority is misplaced inasmuch as the court therein made it clear that the changes in proportion there involved did not result in an over- all appearance which was substantially different. 6Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
