Office Action

§102 §112
DETAILED ACTION Claims 1, 4, 6, 9-10, 12-13, 48-52, 54, 56, 58-59, 61, 64-66 are pending in the instant application. Applicant's election without traverse of group II, claims 48-52, 54, 56 in the reply filed on 06/26/2026 is acknowledged. The requirement is still deemed proper and is therefore made FINAL. Claims 48-52, 54, 56 are examined. Claims 1, 4, 6, 9-10, 12-13, 58-59, 61, 64-66 are withdrawn per 37 CFR 1.142(b). 2. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 48-52, 54, 56 are rejected under 35 U.S.C. 112, first paragraph, as failing to comply with the enablement requirement. The claim contains subject matter, which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. The specification lacks enablement of the term “RBP4 inhibitor”, which are claimed in the method claims. While enabling for RBP4 inhibitor has the structure of PNG media_image1.png 254 314 media_image1.png Greyscale in claim 56, it is not seen where this is enables for other RBLP4 inhibitor. Therefore, the specification lacks enablement for the term “RBLP4 inhibitor” other than the structure in claim 56. 3. 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. (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. Claims 1-5, and 8-15 are rejected under 35 U.S.C. 102(a)(1) and 102(a) as being anticipated by Cioffi et al., US 9434727. Cioffi et al. discloses the instant claimed compound on column 12 as follow: PNG media_image2.png 228 306 media_image2.png Greyscale , which anticipates the instant claims and can be used for treating age-related macular degeneration. The genomic variants are inherently there. There are people has some of these genomic variants and the other people has all or none of these genomic variants. Therefore, the instant claims are anticipated by Cioffi et al. 4. Claims 1-5, and 8-15 are rejected under 35 U.S.C. 102(a)(1) and 102(a) as being anticipated by Lin et al., US 11389444. Lin et al. discloses the instant claimed compound on column 7 as follow: PNG media_image2.png 228 306 media_image2.png Greyscale , which anticipates the instant claims and can be used for treating age-related macular degeneration. The genomic variants are inherently there. There are people has some of these genomic variants and the other people has all or none of these genomic variants. Therefore, the instant claims are anticipated by Lin et al. 5. Claims 1-5, and 8-15 are rejected under 35 U.S.C. 102(a)(1) and 102(a) as being anticipated by Petrukhin et al., WO 2020028723. Petrukhin et al. discloses the instant claimed compound on page 66 as follow: PNG media_image2.png 228 306 media_image2.png Greyscale , which anticipates the instant claims and can be used for treating age-related macular degeneration. The genomic variants are inherently there. There are people has some of these genomic variants and the other people has all or none of these genomic variants.
