Office Action

§102 §103
DETAILED ACTION Claims 1-2, 4, 6-7, 10, 13-17, 21, 23, 29, 34, 39, 45-47 and 49-51, submitted on 11 October 2023, are pending in the application. Claims 2, 6, 10, 13, 15, 34 and 50-51 have been withdrawn. Claims 1, 4, 7, 14, 16-17, 21, 23, 29, 39, 45-47 and 49 are under examination in the instant Office 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 . Election/Restrictions Claims 2, 6, 10, 13, 15, 34 and 50-51 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Group and/or species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 20 January 2026. Applicant’s election without traverse of Group I and the species election of the compound I-17, PNG media_image1.png 194 204 media_image1.png Greyscale , in the reply filed on 20 January 2026 is acknowledged. The Examiner did not find prior art on the elected species. In the search of the claimed species, prior art which reads on the genus and subsequent compounds of the claimed invention was found. Thus, the species election was expanded to include species identified in the below prior art rejection. As detailed in the following art rejection, the generic claim encompassing the elected species was not found patentable. Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Rejections - 35 USC § 103 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1, 7, 14, 16-17, 21, 23, 29, 39, 45-47, and 49 are rejected under 35 U.S.C. 103 as being obvious over Bearss et al. (US Patent No. 11,161,852). The applied reference has a common Assignee and Inventors with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2). Bearss discloses a genus, shown below, similar to that of the Applicant, which reads on the compounds of the instantly claimed invention. This reference teaches compounds which read on the limitations of the genus when A = C10 aryl or 9-10 membered heterocyclyl; X = CH or N; Y = NH; R1 = H; R2 = C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl; R3 = H (Col. 13, Lines 11-61); R4 = PNG media_image2.png 157 200 media_image2.png Greyscale , PNG media_image3.png 139 200 media_image3.png Greyscale , PNG media_image4.png 146 218 media_image4.png Greyscale , PNG media_image5.png 139 215 media_image5.png Greyscale , PNG media_image6.png 139 196 media_image6.png Greyscale , PNG media_image7.png 137 198 media_image7.png Greyscale , PNG media_image8.png 105 166 media_image8.png Greyscale , PNG media_image9.png 106 164 media_image9.png Greyscale , PNG media_image10.png 142 197 media_image10.png Greyscale , PNG media_image11.png 141 199 media_image11.png Greyscale , PNG media_image12.png 144 207 media_image12.png Greyscale , or PNG media_image13.png 136 209 media_image13.png Greyscale (Col. 16-17, Lines 60-67 and 1-33, respectively); R5 = H (Col 13, Line 62). Genus taught by Bearss PNG media_image14.png 266 352 media_image14.png Greyscale (Col 13, Lines 13-26) Genus taught by Applicant PNG media_image15.png 202 180 media_image15.png Greyscale With respect to claim 14, Bearss teaches wherein the A ring can be a C10 aryl (Col. 13, Line 30) which reads on the limitations of the instant claim when PNG media_image16.png 106 89 media_image16.png Greyscale is PNG media_image17.png 94 92 media_image17.png Greyscale . With respect to claim 16, Bearss teaches wherein X is nitrogen (Col. 13, Line 33) which reads on the limitations of the instant claim which recites that the equivalent moiety of the Applicant’s structure, Z, is nitrogen. Regarding claim 17, the genus taught by Bearss, as shown above, does not have an equivalent moiety to the X moiety taught by the Applicant. However, the atom in place of the Applicant’s moiety is a carbon atom with an R3 moiety which reads on the limitations of the instant claim when R3 = H (Col. 13, Lines 33 and 43). Regarding claim 21, Bearss teaches wherein R2 is C1-C6 alkyl, C2-C6 alkenyl, and C2-C6 alkynyl each of which is optionally substituted (Col. 13, Lines 36-40). With respect to claim 23, Bearss teaches wherein R2 is cyclopropyl or cyclobutyl (Col. 14, Line 27) With respect to claim 29, Bearss teaches wherein R2 is PNG media_image18.png 105 77 media_image18.png Greyscale (Col. 14, Lines 46-54). Regarding claim 39, Bearss teaches wherein R4 is isoxazolyl (Col. 13, Line 49) Regarding claim 45, Bearss teaches wherein R4 can be PNG media_image19.png 133 170 media_image19.png Greyscale , PNG media_image20.png 124 178 media_image20.png Greyscale , PNG media_image21.png 126 188 media_image21.png Greyscale , PNG media_image22.png 114 176 media_image22.png Greyscale , PNG media_image23.png 116 164 media_image23.png Greyscale , PNG media_image24.png 121 175 media_image24.png Greyscale , PNG media_image25.png 104 164 media_image25.png Greyscale , PNG media_image26.png 100 155 media_image26.png Greyscale , PNG media_image27.png 115 160 media_image27.png Greyscale , PNG media_image28.png 114 161 media_image28.png Greyscale , PNG media_image29.png 116 168 media_image29.png Greyscale , or PNG media_image13.png 136 209 media_image13.png Greyscale (Col. 16-17, Lines 60-67 and 1-33, respectively); R5 = H (Col 13, Line 62). Regarding claim 46, while Bearss does not exemplify a compound of the instantly claimed invention, the contents of the prior art teach the limitations of a compound of the instant claim (e.g., Compound I-1). With respect to claim 47, Bearss teaches wherein the compound of the disclosure is capable of inhibiting NEK7 and/or modulating the activity of NLRP3 inflammasome (Col. 11, Lines 47-50). With respect to claim 49, Bearss teaches a pharmaceutical composition comprising a pharmaceutically acceptable diluents, excipients, and carriers (Col. 79, Lines 23-26). Allowable Subject Matter Claim 4 is 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. The closest prior art, Bearss, teaches wherein A can be C10 aryl or 9-10 membered heterocyclyl, which reads, in part, on the limitations of independent claim 1. However, Bearss does not teach wherein A is a bicyclic heteroaryl and instead teaches a 5-6 membered monocyclic heteroaryl (Col. 13, Line 30-31). Claim 7 is 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. As shown above, the A ring as taught by Bearss is not explicitly drawn to a 6-membered heteroaryl containing a moiety at an equivalent point similar to that of the Applicant’s genus. Instead, Bearss exemplification of the A ring monocyclic heteroaryl has the nitrogen atom in a different location as shown, PNG media_image30.png 81 199 media_image30.png Greyscale (Col. 28, Lines 17-20).
