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 . 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. Current Status of 18/558,351 This Office Action is responsive to the amended claims of 31 October 2023. Claims 1-14 have been examined on the merits. Claims 1-3, 5-6, 8-9, and 12-14 are currently amended. Claims 4, 7, and 10-11 are original. Priority The effective filing date is 6 May 2022. Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 31 October 2023, is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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. Claims 9-11 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. Claim 9 contains the limitation/word “includes”. This renders the metes and bounds of claim 9 undefined (hence rendering claim 9 indefinite) since the artisan does not know if the limitations following “including” are merely exemplary or are required limitations for the claim. Examiner recommends revising claim 9 to: -- obtaining crystals further comprises [[includes]] additionally introducing a second crystallization solvent -- to render moot this indefiniteness rejection. Claims 10-11, which also contain “includes” are similarly rejected as indefinite. The Examiner recommends a similar strategy of using -- further comprises -- in place of “[[includes]]”, as above, to render moot the indefiniteness rejection against claims 10-11. Conclusion Claims 9-11 are not presently allowable as written. Claims 1-8 and 12-14 are presently allowable as written. There is no known prior art reference that either teaches or anticipates the polymorph of instant claim 1. The reference MacNEIL (MacNeil, Douglas, et. al. “The role of melanocortins in body weight regulation: opportunities for the treatment of obesity.” European J. of Pharmacology. (2002), Vol. 450, pp. 93-109, provided by Applicants – see IDS of 31 October 2023), discloses the compound: PNG media_image1.png 296 386 media_image1.png Greyscale (page 101). However, MacNEIL reference is a close art but not a prior art reference since it does not teach, suggest, or anticipate the polymorphs of the compounds of genus formula I from instant claim 1.
