Office Action

§102
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 . Claims 1-5, 10, 11, 18, 19, 21-24, 29, 32, 33, 39, 40 and 46 are presented for examination. Applicants’ drawings and information disclosure statement filed February 28, 2023 have been received and entered. Applicants’ preliminary amendments filed February 28, 2023 and September 22, 2023 have been received and entered. Applicants’ election filed January 27, 2026 in response to the restriction requirement of December 4, 2025 has been received and entered. The applicants elected the invention described in claims 23, 24 and 29 (Group III) without traverse. Claims 1-5, 10, 11, 18, 19, 21, 22, 32, 33, 39, 40 and 46 are withdrawn from consideration as being drawn to the non-elected invention (37 CFR 1.142(b)). Priority Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) is acknowledged. Claim Objections Claims 24 and 29 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. 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. Claim 23 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 and 5 of U.S. Patent No. 11,219,625 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the present applications teach compounds of formula (III), or salt thereof (A product), and the patented application teaches method of use claims containing the compounds of the present application therein which makes the compound claim of the present application obvious variations of the patented application’s claims. Claim 23 is not allowed. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 23 is rejected under 35 U.S.C. 102(a)(2) as being anticipated by WO 2017/019540 A2, hereby known as Contessa et al. Contessa et al. teach compounds of formula (I), or a salt, solvate, enantiomer, diastereoisomer or tautomer thereof with R1, R2 and R3 substituents that will formulate the present application’s compounds of formula (III) (see page 88, claim 1 to page 93, claim 11). Clearly, the applicants’ compounds of formula (III) are encompassed by the compounds of the cited reference. Therefore, applicants’ instant compounds are anticipated by the cited reference. Claim 23 is not allowed. Any inquiry concerning this communication or earlier communications from the examiner should be directed to KEVIN E WEDDINGTON whose telephone number is (571)272-0587.
