Office Action

§DP
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on 02/12/2026 is being considered by the examiner. Double Patenting 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 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); 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 nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Independent Claim 2 is rejected on the ground of nonstatutory double patenting as being unpatentable over independent claim 1 of U.S. Patent No. 12,455,701. Although the claims at issue are not identical, they are not patentably distinct from each other because both of the inventions are about access-permission table for controlling data movement accessing memory from multiple requestors. Claim 2 of instant application Claim 1 of US 12,455,701 An apparatus comprising: a memory to store an access-permissions table comprising a plurality of entries An apparatus comprising: a memory to store an Inter-Domain Permissions Table (IDPT) having a plurality of entries each entry corresponding to a target address space for data movement operations and having an authorization field usable to identify one or more requester identities authorized by the entry wherein a single entry of the IDPT is to provide a relationship between u an access address space identifier and a plurality of submitter address space identifiers and a data-movement accelerator coupled to the memory and configured, when processing a descriptor submitted from a requester identity, and a hardware accelerator device to allow access to an access address space, corresponding to the access address space identifier, by one or more submitters, determine an entry of the access-permissions table based on a handle in the descriptor, corresponding to the plurality of requester submitter address space identifiers, respectively, based at least in part on the relationship provided by the single entry of the IDPT validate, based on the authorization field associated with the entry, whether the requester identity is authorized by the entry, and perform direct memory access to the target address space when the validation succeeds wherein allowing the access comprises finding the single entry within the IDPT, the single entry being capable of identifying the plurality of submitter address space identifiers including submitter address space identifiers that correspond to the one or more submitters The limitation of claim 2 of instant application has been broadened without specifically mentioning “Inter-Domain Permissions”. Other limitations of instant application is also taught in US 12,455,701 in much broader way essentially executing same feature.
