Office Action

§112
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 . Claims 1-8 are currently pending in this Application. Claim 1 is withdrawn from further consideration by the examiner, 37 CFR 1.142(b), as being drawn to a non-elected invention. Priority FOREIGN APPLICATIONS CHINA 202310352682.1 04/04/2023 Response to Restriction Applicants’ election, with traverse, the invention of Group II, claims 2-8, drawn to a process of preparing products of Formula PNG media_image1.png 223 189 media_image1.png Greyscale , in response filed on March 02, 2018 is acknowledged. The traversal is on the ground(s) that there is a unity of invention and that both the products and method of preparing the product can be examined together, and that there is no undue burden to search all of the claimed inventions. This is not found persuasive because as pointed out in the previous Office Action, restriction for examination purposes as indicated is proper because there would be a serious search and examination burden if restriction were not required because one or more of the following reasons apply: (a) the inventions have acquired a separate status in the art in view of their different classification; (b) the inventions have acquired a separate status in the art due to their recognized divergent subject matter; (c) the inventions require a different field of search (for example, searching different classes/subclasses or electronic resources, or employing different search queries); (d) the prior art applicable to one invention would not likely be applicable to another invention; (e) the inventions are likely to raise different non-prior art issues under 35 U.S.C. 101 and/or 35 U.S.C. 112, first paragraph. In the instant case the invention of Group I is not allowable. Therefore, the restriction requirement is considered proper and is maintained. Applicant is reminded that upon the cancellation of claims to a non-elected invention, the inventorship must be amended in compliance with 37 CFR 1.48(b) if one or more of the currently named inventors is no longer an inventor of at least one claim remaining in the application. Any amendment of inventorship must be accompanied by a petition under 37 CFR 1.48(b) and by the fee required under 37 CFR 1.17(i). Claim Interpretation Examination requires claim terms first be construed in terms in the broadest reasonable manner during prosecution as is reasonably allowed in an effort to establish a clear record of what applicant intends to claim. See MPEP § 2111. Under a broadest reasonable interpretation, words of the claim must be given their plain meaning, unless such meaning is inconsistent with the specification. See MPEP § 2111.01. It is also appropriate to look to how the claim term is used in the prior art, which includes prior art patents, published applications, trade publications, and dictionaries. MPEP § 2111.01 (III). However, specific embodiments of the specification cannot be imported into the claims, particularly where the subject claim limitation is broader than the embodiment. MPEP § 2111.01(II). Compact Prosecution In the interest of compact prosecution, the examiner attempted to reach out to applicants to suggest some Examiner’s Amendment to advance the prosecution of the case. 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. The primary purpose of this requirement of definiteness of claim language is to ensure that the scope of the claims is clear so the public is informed of the boundaries of what constitutes infringement of the patent. A secondary purpose is to provide a clear measure of what applicants regard as the invention so that it can be determined whether the claimed invention meets all the criteria for patentability and whether the specification meets the criteria of 35 U.S.C. 112, first paragraph with respect to the claimed invention.", (see MPEP § 2173). Claim 2-8 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. In the present instance: Claim 2-8 depend on a non-elected claim. The claims recite “midazolam-D3 as claim1”. The claims are considered indefinite because they depend on a non-elected claim. It is suggested that the claims be amended to be as an independent claims and include the structural formula of midazolam-D3 product. Allowable Subject Matter Claims 2-8 would also be allowable once the 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph rejection, outlined above have been overcome. The following is a statement of reasons for the indication of allowable subject matter: The instant elected invention is drawn to a method of preparing midazolam-D3 product of Formula, PNG media_image1.png 223 189 media_image1.png Greyscale as defined in claim 2. The process involves several steps including the formation of several intermediate products. The process of preparing the products of the instant claims are novel and non-obvious over the prior art. The closest prior art is US Patent No. 8,557,981 which discloses process of preparing similar products. US Patent No. US Patent No. 8,557,981 fail to disclose or suggest the modifications necessary to arrive at Applicant's claimed compounds. None of the published processes anticipated, or rendered obvious, the process as described in this application.
