Office Action

§DP
DETAILED ACTION Applicant’s arguments in the response filed 12/12/2025 are acknowledged. Claims 52-81 are pending and will be examined on the merits. 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 Maintained 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 52-81 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 53-54, 56-58, 60-73 of copending Application No. 18/473,965 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because this instant claims are drawn to the same CAR-T cell comprising a CD20 binding heavy chain variable region comprising the same sequences (SEQ ID NOs: 4-6) and methods of treatment comprising administering said CAR-T. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Response to Arguments Applicant's arguments filed 12/12/2025 have been fully considered but they are not persuasive. Applicants argue since the copending application have not yet been examined and no allowable claims have been identified in the copending application, the rejection should be withdrawn. However, the MPEP states the following: If both the application under examination and the reference application have the same patent term filing date, the provisional nonstatutory double patenting rejection made in each application should be maintained until it is overcome. Provisional nonstatutory double patenting rejections are subject to the requirements of 37 CFR 1.111(b). Thus, applicant can overcome a provisional nonstatutory double patenting rejection by filing a reply that either shows that the claims subject to the rejection are patentably distinct from the claims of the reference application, or includes a compliant terminal disclaimer under 37 CFR 1.321 that obviates the rejection. If the reply is sufficient, the examiner will withdraw the nonstatutory double patenting rejection in the application in which it was submitted (see MPEP 804). Since the instant application and the copending application 18/473,965 both have the same priority date of 4/16/2021 the rejection of record is hereby maintained. Conclusion Claims 52-81 are rejected. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
