Appeal No. 2002-2309 Application No. 09/099,386 combined as suggested by the examiner, the skilled artisan would still not know from the combined teachings whether the memory manager in the preferred embodiment should not use duplicate cache tags. Any rejection put forth by the examiner must be supported by substantial evidence in the record, and, when that evidence is lacking in the record, the Board can not and should not resort to unsupported speculation to lend credence to the rejection. See In re Lee, 277 F.3d 1338, 1343, 61 USPQ2d 1430, 1433 (Fed. Cir. 2002), and In re Zurko, 111 F.3d 887, 889, 42 USPQ2d 1476, 1478-79 (Fed. Cir. 1997). The only teaching of record of a memory manger without duplicate cache tags is appellants’ disclosed and claimed invention, and it is not available to the examiner in an obviousness rejection. Thus, the obviousness rejection of claims 1 through 11 and 24 is reversed. With respect to claim 12, and the claims that depend therefrom, the examiner is of the opinion (answer, page 9) that the DTag New State Values 322 and the S REPLY type 325 entries in the Status Vector in Active Transaction Status Array 294 in Figure 14 of Nishtala are a “data movement field” and a “next state field,” respectively. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
