Office Action

§102 §112
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 Claims 1-4, 9-21 and 23-25 are pending in the application. Claims 1-4, 9-14 and 16 are rejected. Claims 1 and 15 are objected to. Claims 17-21 and 23-25 are withdrawn. Restriction/Election of Species Applicant’s election without traverse of Group I, claims 1-4 and 9-16, and the further elected species, shown below, in the reply filed on June 15, 2026 is acknowledged. PNG media_image1.png 197 298 media_image1.png Greyscale Claims 17-21 and 23-25 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on June 15, 2026. As per MPEP § 803.02(III), the examiner will determine whether the entire scope of the claims is patentable. Applicant’s elected species appears to be free of the prior art. Therefore, according to MPEP § 803.02(III): should the elected species be found allowable over the prior art, the examination of the Markush claim will be extended. The prior art search will be extended to cover non-elected species or group of species that fall within the scope of a proper Markush grouping which includes the elected species. The prior art search will not be extended unnecessarily to cover all nonelected species, and need not be extended beyond a proper Markush grouping. However, if prior art is found that anticipates or renders obvious the Markush claims with respect to a nonelected species, the Markush claims shall be rejected and claims to the nonelected species held withdrawn from further consideration. Consequently, the prior art search was extended to include the compounds (i.e., C1, C2, C3, C4 and C5) recited in instant claim 15 as well as the following non-elected species: PNG media_image2.png 161 310 media_image2.png Greyscale , PNG media_image3.png 191 368 media_image3.png Greyscale , PNG media_image4.png 288 366 media_image4.png Greyscale and PNG media_image5.png 204 333 media_image5.png Greyscale . Priority This application is a 35 U.S.C. § 371 National Stage Filing of International Application No. PCT/US2022/045904, filed on October 6, 2022, which claims benefit of Provisional Application No. 63/253,341, filed on October 7, 2021. Information Disclosure Statement The Information Disclosure Statement(s) (IDS) filed on April 5, 2024 and August 12, 2025 are in compliance with the provisions of 37 CFR 1.97 and 1.98. Accordingly, the Examiner has considered the IDS documents and signed copies of the 1449 forms are attached. Claim Objections Claim 1 is objected to because of the following informalities: Claim 1 should be amended to recite “...each occurrence of Y is independently selected from the group consisting of R, F, Cl ... C3-10 heterocycloalkyl, and C5-10 heteroaryl...” for sake of clarity and consistency. Appropriate correction is required. Claim Rejections - 35 USC § 112(d) The following is a quotation of 35 U.S.C. § 112(d): (d) REFERENCE IN DEPENDENT FORMS — Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. § 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 12 is rejected under 35 U.S.C. § 112(d) or pre-AIA 35 U.S.C. § 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 12 recites the expression “Z1 is H, and R1 is absent.” Parent claim 1, however, is narrower in scope than dependent claim 12 as parent claim 1 does not provide for variable definitions wherein “Z1 is H, and R1 is absent.” Therefore, dependent claim 12 fails to further limit the subject matter of parent claim 1. It is suggested Applicant replace the expression “Z1 is H, and R1 is absent” with “-(Z1)n1-R1 is H” (as recited in parent claim 1) to overcome this issue of improper dependent form. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim Rejections - 35 USC § 102 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 1-4 and 16 are rejected under 35 U.S.C. § 102(a)(1) as being anticipated by CAS Registry No. 179125-68-9 (entered STN on August 7, 1996). (1 of 5) CAS Registry No. 179125-68-9 corresponds to the following chemical structure: PNG media_image2.png 161 310 media_image2.png Greyscale .
