Appeal No. 1998-0714 Application No. 08/092,622 reduced each year as the cost and technology change. Nonetheless, Kobayashi discloses (column 7, lines 59-63) that the central elements of the PPM could be incorporated in a module that is 9.06" long, 5.12" wide, and 0.91" high, which is sized and shaped so that the housing could be physically mounted in a disk drive slot. Thus, Kobayashi meets all of the limitations of claim 1 with Blackborow being merely cumulative. Although the rejection is based on Kobayashi in view of Blackborow, it is permissible to affirm the rejection relying on only Kobayashi. See In re Bush, 296 F.2d 491, 496, 131 USPQ 263, 266-67 (CCPA 1961). Accordingly, we will affirm the rejection of claim 1 and of claim 2, grouped therewith. As to the second group of claims, representative claim 3 requires that the second means for interfacing "allows communications from one central processing unit to a second central processing unit." As stated above, Kobayashi includes a single central processing unit and precludes adding a second central processing unit. Therefore, the combination fails to meet the claim limitation. Accordingly, we cannot sustain the rejection of claim 3 nor of the claims grouped therewith, claims 4 through 8. 7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
