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 . DETAILED ACTION This action is in response to a request for continued examination received May 20th, 2026. Status of Claims Claims 1-2, 45, 49, 51, 55, 70, 78, 80, 102, 105, 137-138, 141, 144, 147, 152-153, 158, and 160-161 are pending in the instant application. Claims 3-44, 46-48, 50, 52-54, 56-69, 71-77, 79, 81-101, 103-104, 106-136, 139-140, 142-143, 145-146, 148-151, 154-157, 159, and 162-164 have been canceled. Claims 153, 158, and 161 stand withdrawn. Withdrawn Rejections/Objections Applicant’s amendment is sufficient to overcome the rejections of Claims 1-2, 45, 49, 51, 55, 70, 78, 137-138, 141, and 144 under 35 U.S.C. 102(a)(1). These rejections are hereby withdrawn. Claim Rejections - 35 USC § 112 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. Claim 1 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 the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 1 recites the broad recitation “R4 is hydrogen, substituted or unsubstituted alkyl, -C(=O)ORA, -C(=O)RA, -C(=O)N(RA)2, or a nitrogen protecting group” in lines 3-4 of Page 3 of the instant Claims and “each R5 is independently -ORA, -N(RA)2, substituted or unsubstituted alkyl, substituted or unsubstituted carbocyclyl, substituted or unsubstituted aryl, substituted or unsubstituted heterocyclyl, or substituted or unsubstituted heteroaryl” at lines 5-7 of Page 3 of the instant Claims, and the claim also recites “R4 is hydrogen, substituted alkyl, -C(=O)ORA, -C(=O)RA, -C(=O)N(RA)2, or a nitrogen protecting group” at lines 25-26 of Page 3 of the instant Claims and “each R5 is independently -ORA, -N(RA)2, substituted or unsubstituted hetrocyclyl, or substituted or unsubstituted heteroaryl” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. 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 1-2, 45, 51, 70, 78, 80, 102, 137-138, 141, 144, 152, and 160 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by WO 2015/090226 (machine translation provided; hereinafter referred to as WO ‘226).
