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 . Application Status The preliminary amendment filed on 4/26/2024 is acknowledged. Claims 1, 10-14, 20-22, 24-25, 33-35, 37-42 are currently pending and under consideration. Information Disclosure Statement The information disclosure statements filed on 1/04/2024, 8/13/2024 and 3/13/2025 are acknowledged and have been considered except where lined through. Claim Rejections - 35 USC § 102 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 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. Claim(s) 1, 10-13, 20-22, 24-25, 37-39 and 41-42 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Berdini et al. (US2008/0167309A1, 2008-07-10). Berdini et al teach compounds for use in the prophylaxis or treatment of a disease state or condition mediated by a cyclin dependent kinase, the compound having the formula (I): PNG media_image1.png 108 161 media_image1.png Greyscale (abstract). Specifically, Berdini et al. teach compounds including, but not limited to, PNG media_image2.png 188 325 media_image2.png Greyscale (paragraph 0758), PNG media_image3.png 194 302 media_image3.png Greyscale (paragraph 0755), PNG media_image4.png 201 306 media_image4.png Greyscale (paragraph 0773), and PNG media_image5.png 228 360 media_image5.png Greyscale (cmpd 15, page 61) which read on the instantly claimed compound wherein R1 and R2 are H, Ring B is a phenyl, Rb is ORa (e.g. ethoxy) or a halogen, n=2 to 3, R3 is a heterocycloalkyl or aryl and R3a is ORa (Ra is a C1-C6 heteroalkyl) or NRcRd, wherein Rc and Rd together form a ring. With regards to the diseases, Berdini et al. teach that cyclin dependent kinase mediated disease include, but are not limited to, toxin-induced or alcohol related liver diseases (paragraph 0544). Moreover, Berdini et al. teach pharmaceutical compositions comprising said compounds, wherein the pharmaceutical compositions further comprises a pharmaceutically acceptable carrier (paragraph 0591). Conclusion Therefore, claims 1, 10-13, 20-22, 24-25, 37-39 and 41-42 are rejected. Claims 14, 23. 33-35 and 40 are 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.
