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 . DETAILED ACTION RCE Nonfinal Rejection Request for Continued Examination A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant’s submission filed on 12/08/2025 has been entered. Claim Status Claims 1-17 and 23-37 were pending as of the prior Office Actions and Advisory Action. Upon RCE amendment entrance, Claims 1-17 and 23-37 are pending examination. Priority PNG media_image1.png 78 346 media_image1.png Greyscale No foreign priority was claimed in the Instant Application; EFD is 12/23/2021. Information Disclosure Statement All references have been considered in the one (1) IDS(s) filed on 05/11/2026 unless marked with a strikethrough. Review of Claims for Clarification Examiner acknowledged election of Group I: Claims 1-17 made without traverse. Claims 23-24 were withdrawn as being drawn to a non-elected invention. Elected Specie: Applicant elected Cpd. No. 84: N-((1-(difluoromethyl)-4-(4-(trifluoromethyl)phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-b]pyridin-6-yl)methyl) acrylamide, the structure which is shown below. The elected specie chosen (Cpd. No. 84) reads on Claims 1-2, 5-6, 8-14, 17. Newly added Claims 25-37 were also examined. For clarification: the Elected Specie (Cpd. 84 above) reads on Claims 1-2, 5-6, 9-14, 17 and newly added Claims 25, 31, 33. PNG media_image2.png 280 296 media_image2.png Greyscale Pursuant to 37 CFR 1.142(b), Claims 3-4, 7-8, 15-16, 18-24, 26-30, 32, 34-37 are withdrawn as being drawn to a nonelected invention. The elected specie (Cpd. 84) was not identified in prior art. The elected specie would be allowable if drafted as an independent claim to the elected specie alone. Expanded Specie: Examiner expanded her search to additional species within the genus, per MPEP § 802.03. An expanded specie was found which read on Claims 1-2, and 5-6 and 17. Therefore, pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, the expanded specie does not read on Claims 3-4, 7-16, and 18-37 and therefore are withdrawn. Information Disclosure Statement Examiner acknowledged IDS(s) submitted in the Office Action mailed 05/11/2026. Examiner Responses to Amendments/Arguments The issues raised in the Office Action are addressed below: I. Claim Amendments – Upon amendment entrance, Applicant amended Claims 1 and 2 with changes in the limitations; Claim 11 has been amended editorially. II. Withdrawn Claims Rejection – Applicant' s arguments with respect to claim(s) 1, 2, 5, 6, 11, 12 and 25-37 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Though the elected specie is free of art, the amended claims read on a new expanded specie. III. RCE Claims Rejection – The amended claims read on a different expanded specie, a new rejection is listed below. 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2, 5-6 and 17 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by N. Luise, et. Al in “A Continuous Flow Strategy for the Facile Synthesis and Elaboration of Semi-Saturated Heterobicyclic Fragments” (Eur. J. Org. Chem., 2019: 1341-1349; hereinafter “Luise”). With respect to Claims 1-2, 5-6 and 17, Luise developed a continuous flow hydrogenation strategy for the efficient synthesis of semi-saturated heterobicyclic fragments with high sp³ content, targeting fragment-based drug discovery (FBDD). On pg. 1342, Scheme 1 (see below), the generated fragments, with appropriate physicochemical properties, present diverse hydrogen- bonding pharmacophores and useful vectors for their synthetic elaboration in the optimization stage PNG media_image3.png 216 834 media_image3.png Greyscale Conclusion Claims 1-2, 5-6, and 17 are rejected.
