Office Action

§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 1-9 are currently pending in the instant application. Claim 3 is rejected, claims 1-2 are objected and claims 4-9 are considered allowable in this Office Action. I. Priority The instant application is a 371 of PCT/IN2022/051099, filed on December 19, 2022 and claims benefit of Foreign Application INDIA 202111061087, filed on December 25, 2021. II. Information Disclosure Statement The information disclosure statement (IDS) submitted on June 24, 2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has been considered by the examiner. III. Rejections Claim Rejections - 35 USC § 112 The following is a quotation of the second paragraph of 35 U.S.C. 112: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 3 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention. Specifically, claim 3 lists various compounds (e.g. compound 2) that are used or prepared in the claimed process but does not provide the structure of these compounds. The examiner must refer to the specification to find the structures of the various compounds being referred in claim 3. A claim referring to the specification is improper except in rare instances and fails to particularly point out the subject matter that applicant regards as the invention. Ex parte Fressola, 27 USPQ 2d 1608 (1993). To overcome the rejection, Applicants need to insert the structures of each compound number listed to overcome the rejection. IV. Objections Claim Objections Claims 1 and 2 are objected to because of the following informalities: claim 1 does not have the term “and” in between the last structures in variables R1, R2 and R3. Claim 1 is objected because the structures in variable R2 are difficult to read. Claim 1 is missing a period at the end of the claim. Each claim begins with a capital letter and ends with a period (MPEP 608.01 (m)). Claim 2 does not have the term “and” in between the last two compounds listed in the claim. Appropriate correction is required. ***closest prior art is Zhou, et al. (Mol Divers (2013) 17: 197-219) teaches quinazoline compound such as PNG media_image1.png 78 173 media_image1.png Greyscale which have 2 substituents on the benzene ring the quinazoline ring but does not teach compounds with only 1 substituent on the benzene ring as seen in the instant claimed compounds PNG media_image2.png 92 126 media_image2.png Greyscale .
