Office Action

§DOUBLEPATENT
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 . Priority This application is a 371 of PCT/EP2021/084987 (12/09/2021) and claims foreign priority to EP 20213020.9 (12/10/2020). Status Claim rejections not reiterated in this action are withdrawn. 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 1-11 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of U.S. Patent No. 12195448 in view of Tan et al. (US20130210798) as detailed supra and in view of Meanwell (J. Med. Chem. 2018, 61, 5822−5880). Although the claims at issue are not identical, they are not patentably distinct from each other because the patent claims the following compound having the same utility as Tan: PNG media_image1.png 431 401 media_image1.png Greyscale which differs from the instant claims by a difluoromethyl substituent on the pyrazole ring. Meanwell teaches fluorine bioisosteres in drug design including modifying a difluoromethyl group to a trifluoromethyl group to improve pharmaceutical properties, including stability (Table 7, Table 22). One of ordinary skill in the art would have considered modifying the patent compound in the well-known manner suggested by Meanwell and arrive at the claimed invention with a reasonable expectation of success. Claims 1-11 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 7-11, 13 of copending Application No. 17667410 (reference application) in view of Tan et al. (US20130210798) as detailed supra and in view of Meanwell (J. Med. Chem. 2018, 61, 5822−5880). Although the claims at issue are not identical, they are not patentably distinct from each other because the reference application claims the difluoromethyl substituted pyrazole and as detailed above is rendered obvious. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-11 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 11, 15-21 of copending Application No. 18893545 (reference application) in view of Tan et al. (US20130210798) as detailed supra and in view of Meanwell (J. Med. Chem. 2018, 61, 5822−5880). Although the claims at issue are not identical, they are not patentably distinct from each other because the reference application claims the difluoromethyl substituted pyrazole and as detailed above is rendered obvious. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-11 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-11 of copending Application No. 18256650 (reference application) in view of Tan et al. (US20130210798) as detailed supra and in view of Meanwell (J. Med. Chem. 2018, 61, 5822−5880). Although the claims at issue are not identical, they are not patentably distinct from each other because the reference application claims the difluoromethyl substituted pyrazole and as detailed above is rendered obvious. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-11 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-11 of copending Application No. 18256645 (reference application) in view of Tan et al. (US20130210798) as detailed supra and in view of Meanwell (J. Med. Chem. 2018, 61, 5822−5880). Although the claims at issue are not identical, they are not patentably distinct from each other because the reference application claims the same compound and as detailed above is rendered obvious. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Response to Remarks - Double Patenting Applicant requests that the rejection be held in abeyance. This is not persuasive; thus the rejections are maintained. Conclusion No claims allowed. 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.
