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 . DETAIL ACTION This office action is a response to a 371 application filed -----4/4/2023, which is a national stage application of PCT/US2021/071692 filed 10/4/2021, which claims domestic priority to 63/087,780 filed 10/5/2020. As filed, claims 1-10, 20-22, and 24-29 are pending; and claims 11-19, 23, and 30 are cancelled. Information Disclosure Statement The information disclosure statement (IDS) submitted on 9/21/2023 has been considered by the Examiner. Claim Rejections - 35 USC § 112(b) The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: 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. Claims 26-29 are 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 the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 26, the claim is dependent of claim 25 and recites the phrase, “a mutation in the Bcr-Abl tyrosine kinase gene” wherein the word, “the”, requires antecedent basis, and it is unclear where applicant has defined “a” Bcr-Abl tyrosine kinase gene in claims 25 and 26. Without antecedent basis, the claim is rendered indefinite. Regarding claim 27, the claim is dependent of claim 26, and it failed to correct the indefiniteness issue of claim 26, which rendered the claim indefinite. Regarding claim 28, the claim is dependent of claim 25 and recites the phrase, “ one or more mutations in the Bcr-Abl tyrosine kinase gene” wherein the word, “the”, requires antecedent basis, and it is unclear where applicant has defined “a” Bcr-Abl tyrosine kinase gene in claims 25 and 28. Without antecedent basis, the claim is rendered indefinite. Regarding claim 29, the claim is dependent of claim 28, and it failed to correct the indefiniteness issue of claim 28, which rendered the claim indefinite. 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, 2, 5, 6, 9, and 22 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chemical Abstract Registry No. 1262291-12-2, hereinafter CAS122. Regarding claims 1, 2, 5, 6, 9, and 22, CAS122 teaches the following compound or pharmaceutical composition thereof (with unbuffered water), which meets all the limitations of these claims. PNG media_image1.png 216 378 media_image1.png Greyscale PNG media_image2.png 86 1294 media_image2.png Greyscale Wherein: instant variable X is CR8; instant variable R8 is H; instant variable R2 is pyridine substituted by two R6 groups; one of R6 groups is chlorine, the other R6 group is -NR4NR5; instant variable R4 is H; instant variable R5 is cyclohexyl; instant variable R0 is -NH-R3; and instant variable R3 is ethyl. Claims 1, 2, 5, 6, 9, 22, and 24 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Patent No. 8,435,980, hereinafter Florjancic. Regarding claims 1, 2, 5, 6, 9, 22, and 24, Florjancic, for instance, teaches the following compound or pharmaceutical composition thereof for treating acute myelocytic leukemia, which meets all the limitations of these claims. PNG media_image3.png 546 644 media_image3.png Greyscale (abstract) PNG media_image4.png 66 542 media_image4.png Greyscale (column 89, example 79) PNG media_image1.png 216 378 media_image1.png Greyscale (structure of example 79) PNG media_image5.png 262 632 media_image5.png Greyscale (column 48, lines 58-67) PNG media_image6.png 400 620 media_image6.png Greyscale (column 49, lines 54-67) Claim Objections Claims 1-10, 20-22, 24, and 28 are objected to because of the following informalities: Regarding claims 1-10, 20-22, and 24, the claims recites the phrase, “mixture of any of the foregoing”. Such expression can be clarified by reciting -- mixture of the pharmaceutically acceptable salt, solvate, hydrate, or co-crystal thereof --. Regarding claim 28, the claim recites the phrase, “the human having refractory leukemia has one or more mutations”. Such expression can be clarified by reciting -- the human has refractory leukemia, and the refractory leukemia has one or more mutations --. Appropriate correction is required. Allowable Subject Matter Claim 25 is 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. Conclusion Claims 1, 2, 5, 6, 9, 22, 24, and 26-29 are rejected. Claims 1-10, 20-22, 24, 25, and 28 are objected. Claims 11-19, 23, and 30 are cancelled.
