Appeal No. 2006-2217 Reexamination Control Nos. 90/006,789 and 90/007,420 Interfacing Dynamic RAM to iAPX 86, 88 Systems Using the Intel 8202A and 8204, Application Note AP-97A, Intel Corp., April 1982, pages 3-110 to 3-145 ("AP-97A"). 51C64H High Performance Ripplemode™ 64K x 1 CHMOS Dynamic RAM, Intel Corp., pages 2-1 to 2-20, June 1984 ("51C64H"). iSBC® MEM/312/310/320/340 Memory Boards User's Guide, Intel Corp., February 1985 ("iSBC MEM/3XX"). Claims 1, 6, 12, and 17 are rejected under 35 U.S.C. § 103(a) as unpatentable over "Multibus II," "82C08," "51C64H," and Bruce. "iSBC MEM/3xx" are applied as evidence of the level of ordinary skill in the art. Obviousness Factual findings Scope and content of the prior art Scope The "scope" of the prior art relates to whether references are from analogous art. See In re Deminski, 796 F.2d 436, 442, 230 USPQ 313, 315 (Fed. Cir. 1986) (the reference must either be in the field of the applicant's endeavor or, if not, then be reasonably pertinent to the particular problem with which the inventor was concerned); Stratoflex, Inc. v. Aeroquip Corp., 713 F.2d 1530, 1535, 218 USPQ 871, 876 (Fed. Cir. 1983) ("The scope of the prior art has been defined as that 'reasonably pertinent to the particular problem with which the inventor was involved'."). The field of inventor's endeavor is memory controllers for "page mode" access of DRAMs in a system having "requesting agents and "replying agents" connected to a "system bus," in particular, the Multibus II standard. "Multibus II" and "iSBC MEM/3XX" both relate to memory access in the Multibus II system and are within the field of endeavor. "82C08" relates to a memory controller with "page mode" and "51C64H" is a DRAM with page mode, which can be controlled by "82C08"; thus, both are within the field of endeavor. Patent Owner argues in connection with the examiner's rejection that Bruce is nonanalogous art (and, therefore, not within the scope of the prior art) (Br48-50). These arguments are addressed in detail in connection with the rejection of claims 6 and 17. However, the short answer is that Bruce discloses apparatus for detecting and crossing a page boundary in "page mode" memory accesses and is at least reasonably pertinent to the same problem facing the inventor. The apparatus is, in fact, identical. Since Bruce also describes memory - 13 -Page: Previous 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 NextLast modified: November 3, 2007
