Office Action

§DP
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Obvious-type Double Patenting (ODP) Rejections The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). Claims 21-22, 26-29, and 33-36 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 16-20 of U.S. Patent 12/197358 hereinafter ‘358. Although the conflicting claims are not identical, they are not patentably distinct from each other. For example, Claims 21-22, 26-29, 33-36, and 40 of instant Application, respectively contain elements of claims 16-20 of the ‘358 as follows: Claims Instant Claims ‘358 21, 28, 35 a memory device instructions processors an accelerator device a guest UMD a virtualized instance a workload a SWQ a request a write a completion status a number of retries a retry threshold a determination a host KMD 16 medium instructions processor an accelerator device a UMD (within guest) a virtualized instance a workload a SWQ a request a write a completion status a number of retries a retry threshold determining KMD (of a host) 22, 29, 36 query 17 querying 26 graphic engines 18 a graphic processor a plurality of … 27, 34 a portion of graphic engines 18 a graphic processor a plurality of … Therefore, claims 16-20 of the ‘358 anticipate(s) the claims of instant application above. Allowable Subject Matter Claims 21-40 would be allowable with a proper Terminal Disclaimer to overcome the rejection(s) under ODP, set forth in this Office action.
