Office Action

§102
DETAILED 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 . Priority 2. The instant application is a national stage entry of PCT/EP2022/076491, filed September 23, 2022. 3. Acknowledgment is made of applicant's claim for foreign priority under 35 U.S.C. 119(a)-(d) by application no. GB2113588.4 filed in the United Kingdom on September 23, 2021, which papers have been placed of record in the file. Information Disclosure Statement 4. The information disclosure statements (IDS) submitted on August 6, 2024; January 14, 2025; February 18, 2026 were is in compliance with the provisions of 37 CFR 1.97 and 37 CFR 1.98. The IDS document was considered. A signed copy of form 1449 is enclosed herewith. Election/Restrictions 5. Applicant’s election without traverse of Group I in the reply filed on May 29, 2026 is acknowledged. 6. In accordance with the MPEP 803.02, if upon examination of the elected species, no prior art is found that would anticipate or render obvious the instant invention based on the elected species, the search of the Markush-type claim will be extended (see MPEP 803.02). If prior art is then found that anticipates or renders obvious the non-elected species, the Markush-type claim will be rejected. It should be noted that the prior art search will not be extended unnecessarily to cover all non-elected species. Should Applicant overcome the rejection by amending the claim, the amended claim will be reexamined. Id. The prior art search will be extended to the extent necessary to determine patentability of the Markush-type claim. Id. In the event prior art is found during reexamination that renders obvious or anticipates the amended Markush-type claim, the claim will be rejected and the action made final. Id. 7. As per MPEP 803.02, the Examiner will determine whether the entire scope of the claims is patentable. Applicants' elected species PNG media_image1.png 114 233 media_image1.png Greyscale makes a contribution over the prior art of record. Therefore, according to MPEP 803.02: should the elected species appear allowable, the search of the Markush-type claim will be extended. If art is found on a non-elected species, the Markush-type claim shall be rejected and claims to the nonelected invention held withdrawn from further consideration. Since art was found on a non-elected species, subject matter not embraced by the elected species is therefore withdrawn from further consideration. It has been determined that the entire scope claimed is not patentable. Status of Claims 8. Claims 1-12, 15-17, 20, and 23 are pending in the instant application. Claims 4, 8, 15-17, 20, and 23 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a non-elected invention and species. Therefore, claims 1-3, 5-7, and 9-12 read on an elected invention and species and are therefore under consideration in the instant application. Claim Rejections - 35 USC § 102 9. 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 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. 10. 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. 11. Claims 1-3, 5-7, and 9-12 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by WO 2011/025690. WO 2011/025690 teaches anticipatory compounds compositions, including for example: Compounds 342 and 343 in Table 9 on page 176: PNG media_image2.png 137 279 media_image2.png Greyscale PNG media_image3.png 173 639 media_image3.png Greyscale Wherein formula I, the ring comprising Q1 to Q5 represents phenyl, R1 is H, A is phenyl subsituted with Z2, Z2 is Ra4, Ra4 is alkyl substituted with one or more G1, wherein the one or more G1 are =O and -N(Rb5)(Rc5) wherein Rb5/Rc5 are linked together to form a piperazine ring substituted by -H or -C(=O)-Me. Pharmaceutical compositions are taught starting at page 30. Conclusion 12. No claims are allowed. 13.
