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 . Applicant’s amendment and argument of 2/12/26 are entered. Claim 1 is amended. Claims 1, 7-15, 17, and 19-22 remain pending and are considered herein. 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, 7-15, 17, and 19-22 remain rejected on the ground of nonstatutory double patenting as being unpatentable over the claims, each separately, of U.S. Patent Nos. 10,130,659; 10,166,257; 10,272,113; 10,363,273; 10,463,697; 10,646,517; 10,653,723; 10,905,718; 10,925,900; 10,933,094; 10,946,044; 10,946,045; 10,953,046; 10,953,047; 11,007,225; 11,013,770; 11,083,752; 11,202,803; 11,202,804; 11,241,456; 11,273,181; 11,364,266; 11,517,592; 11,401,507; 12,121,541; and 11,998,568.

Applications: Method of Expanding TILs Claims 1, 7-15, 17, and 19-22 remain provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over the claims, independently, of copending Application Nos. 17/147,412*; 17/997,648; 17/997,731; 18/262,365; 18/262,843; 18/291,536; 18/337,454; 18/429,006; 18/551,138; 18/551,586; 18/555,513; 18/560,898; 18/609,772; 18/619,119; 18/661,510; 18/668,092; 18/690,067; 18/693,508; 18/707,719; 18/781,928; 18/832,901; 18/849,440; 18/858,710; 18/957,327; 18/957,327 and 18/984,595. (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the references are drawn to methods of expanding TILs, but do not necessarily contain the same steps and structure. On the other hand, the essential written description for the subject matter claimed provides for the limitations such that the same subject matter is claimed. Thus, in light of the patents, the Artisan would make the invention, as it is claimed, and provided the same essential written description, and would expect success for the same reasoning. Further there is no restriction excluding the rejections. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Response to Argument – NSDP rejections, pending Applications Applicant’s argument of 2/12/26 has been considered but is not persuasive. Applicant argues the claims are not obvious variants, broadly averring the same, without particularity (pp. 5-6) and they should be withdrawn as being to earlier filed Applications (p. 7). Such is not persuasive. The claims are properly rejected as NSDP, requiring a terminal disclaimer. As far as being the earlier filed Application, they will not be withdrawn, unless no other issue exist, including all the rejections against the patents for NSDP, addressed above. TILs Claims 1, 7-15, 17, and 19-22 remain provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over the claims, independently, of copending Application Nos. 17/817,226*; 17/817,239*; 17/817,247*; 17/817,273*; 17/823,419*; 17/823,448*; 17/856,806*; 18/555,513; and 18/984,525. (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the references are drawn to TILs themselves, including product by process in instances, which requires, in the claims or as part of the essential written description for the claimed subject matter, providing the same steps. Thus, in light of each of the references, the invention is obvious. One would make the subject matter in process of making the TILs, and expect success, as it is claimed or provided as essential written description for the making of the TILs claimed. Further there is no restriction excluding the rejections. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Response to Argument – NSDP rejections, pending Applications Applicant’s argument of 2/12/26 has been considered but is not persuasive. Applicant argues the claims are not obvious variants, broadly averring the same, without particularity (pp. 5-6) and they should be withdrawn as being to earlier filed Applications (p. 7). Such is not persuasive. The claims are properly rejected as NSDP, requiring a terminal disclaimer. As far as being the earlier filed Application, they will not be withdrawn, unless no other issue exist, including all the rejections against the patents for NSDP, addressed above. Method of Treating Cancer Claims 1, 7-15, 17, and 19-22 remain provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over the claims, independently, of copending Application Nos. 16/969,362; 17/050,552; 17/110,179; 17/810,540; 17/817,217*; 17/817,276*; 17/823,454*; 17/856,793*; 18/247,877; 18/256,421; 18/256,798; 18/256,853; 18/291,536; 18/410,900; 18/674,562; 18/707,719; 18/745,958; 18/781,928; 18/810,044; 18/832,901; 18/858,710; and 18/886,988. (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the reference claims are drawn to treating cancers. However, the same either claims the same process of making the TILs, or claims the TILs in the use, of which the essential written description fills in those portions not directly claimed. Thus, the Artisan would have found the invention obvious in light of these patents. The Artisan would make the invention, in the process of treating the cancer. The Artisan would expect success, as it is claimed, or provided by way of essential written description for the claims. Further there is no restriction excluding the rejections. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Response to Argument – NSDP rejections, pending Applications Applicant’s argument of 2/12/26 has been considered but is not persuasive. Applicant argues the claims are not obvious variants, broadly averring the same, without particularity (pp. 5-6) and they should be withdrawn as being to earlier filed Applications (p. 7). Such is not persuasive. The claims are properly rejected as NSDP, requiring a terminal disclaimer. As far as being the earlier filed Application, they will not be withdrawn, unless no other issue exist, including all the rejections against the patents for NSDP, addressed above.
