Office Action

§DOUBLEPATENT
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 . Status of the Claims Claims 1-20 are pending. 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- 20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 5-6, 8-11, 13-17, 35-38 of U.S. Patent No. 11851673, and claims 1 and 4-17 of U.S. Patent No. 12123013. Although the claims at issue are not identical, they are not patentably distinct from each other because the claimed T cell composition is a product of the method claimed in US12123013, which is a method of using the vector claimed in US11851673. The table below is helpful to illustrate the similarity, and the nearly word-for-word identical nature of the present claims to the allowed claims of US11851673 and US12123013. Present application claim Nearly identical analogous claim in US11851673 (Application 17/197,927) Nearly identical analogous claim in US12123013 (Application 18/501,269) 1 – composition comprising a T cell transduced with a vector with specific WPRE mutations. 1 – a vector comprising specific WPRE mutations 1 – method of preparing T cells comprising transducing T cells with a vector with specific WPRE mutations 2 5 5 3 6 - 4 8 6 5 9 7 6 10 8 7 11 9 8 13 10 9 14 11 10 15 12 11 16 13 12 17 14 13 35 15 14 36 16 15 37-38 17 16 - 1, 16 (A method of preparing T cells for immunotherapy necessarily implies the administration of these cells to a subject. Then claim 16 teaches that the composition further comprises an RNA molecule) 17 - 4 18 - 1 (A method of preparing T cells for immunotherapy necessarily implies the administration of these cells to a subject) 19 - 1 (A method of preparing T cells for immunotherapy necessarily implies the administration of these cells to a subject) 20 - 1 (Method results in the claimed composition of T cells) Conclusion Claims 1-20 are rejected.
