Office Action

§DP
DETAILED ACTION 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 . 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. Claims 1-3 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3 respectively; Claims 8-10 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 8-10 respectively; Claims 15-17 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 15-17 respectively, of copending Application No. 18/339916 (US Pub. 2023/0422173 A1). Although the claims at issue are not identical, they are not patentably distinct from each other because the scopes of claims 1-3, 8-10 and 15-17 of the present application merely broaden the scope of the US Application No. 18/339916 published claims 1-3, 8-10 and 15-17 respectively by eliminating some characters/functions. It has been held that the omission an element and its functions is an obvious expedient if the remaining elements perform the same as before. In re Karlson, 136 USPQ 184 (CCPA). Also, note Ex parte Rainu, 168 USPQ 375 (Bd.App.1969); omission of a reference element whose function is not needed would be obvious to one skilled in the art. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Allowable Subject Matter Claims 4-7, 11-14 and 18-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Xia et al, US Pat. 12598644 B2, discloses multiple link device (MLD) apparatus for communication in wireless network while providing dynamic power saving (PS) for access point (AP) and non-AP stations, has cross-link signal that suspends and resumes target wait time (TWT) agreements and schedules for select TWT elements. Lu et al, WO 2023/159404 A1, discloses a communication method and a multilink device (MLD) comprise: a first MLD executing a first operation, with which a non-access point (non-AP) MLD is affiliated, to enter a monitoring operation state before the start point of a first restricted-target wake time (r-TWT) service period (SP). Naik et al, US Pub. 2023/0199641 A1, discloses low latency solutions for restricted target wake time (R-TWT) during multi-link operation (MLO).
