Office Action

§DP
Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Request for continued examination A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 11/14/2024 has been entered. DETAILED ACTION As filed, claims 12, 15, 17, 18, 20, 43-45 are pending of which claim 12 is amended. Claims 44-46 are newly added. Claims 1-11, 13, 14, 16, 19, 21-42 are cancelled. Response to Remarks Applicant’s amendments have been fully considered and are entered. The status for each rejection and/or objection in the previous Office Action is set out below. The rejection of claims 12, 15, 17, 18, 20, and 43 under 35 U.S.C. §103(a) over US 20070129282,by Ahlem, 6/7/2007 is withdrawn in view of claim amendments to specify the characterization data of the claimed crystalline solvate of PNG media_image1.png 200 400 media_image1.png Greyscale . The NSDP rejections of are maintained/modified in view of the amendments to claims. The requisite Terminal Disclaimers were not submitted by Applicants. The examiner had a telephone conversation with Applicant's Representative regarding submission of terminal disclaimer. It was noted that the Applicants prefer an office action to be issued at this time. Claim Objections 1.Claims 15, 17, 18, 20, 43-45 are objected to because of the following informalities: the recitation in said claims “Claim” should be changed to lower case. 2.The recitation in claim 12 “essentially” should be change to avoid potential indefiniteness issues. 3. Claims 44 and 46 are objected to because of the following informalities: the recitation “10° C./min”; “20° C. to 100° C. “ contains extra punctuation. Appropriate correction is required. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. 1.Claims 12, 15, 17, 18, 20, 43-46 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8 of U.S. Patent No. 10,995,112 in view of US 2008/0153792 by Frinke et al June 2008. Claims 1-8 of the patent teach a solid form of 17a-ethynylandrost-5-ene-3b,7b,17b -triol but do not teach the use of such for the treatment of conditions. However, the patent discuss treatment of such conditions with same crystalline solvates as claimed with the same characterization data as shown on Figures 1-6 of the ‘112 patent. Furthermore, the ‘792 publication teaches on [0062]-[0063] and [0044] the treatment of inflammatory condition such as inflammatory bowel, lung conditions, cystic fibrosis, acute asthma, chronic asthma with 17α-ethynylandrost-5-ene-3β,7β,17β -triol (instant claims 12). Regarding instant claims 25 and 26, the ‘792 publication teaches on [0002], [0023] and [0044] the treatment of condition such as lung conditions, cystic fibrosis, acute asthma, chronic asthma with 17α-ethynylandrost-5-ene-3β,7β,17β -triol. Thus, it would have been obvious for one of ordinary skill in the art to have employed the solid compound of the patent in the method of the ‘792 publication. There would have been a reasonable expectation of success given the similar purposes of the references. 2.Claims 12, 15, 17, 18, 20, 43-46 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8 of U.S. Patent No. 8,518, 922 in view of US 2008/0153792-A1 06-2008.

However, the ‘792 publication teaches on [0062]-[0063] and [0044] the treatment of inflammatory condition such as lung conditions, cystic fibrosis, acute asthma, chronic asthma with 17α-ethynylandrost-5-ene-3β,7β,17β -triol (instant claims 12,13). Regarding instant claims 25 and 26, the ‘792 publication teaches on [0002], [0023] and [0044] the treatment of condition such as lung conditions, cystic fibrosis, acute asthma, chronic asthma with 17α-ethynylandrost-5-ene-3β,7β,17β -triol There would have been a reasonable expectation of success given the similar purposes of the references. 3.Claims 12, 15, 17, 18, 20, 43-46 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 9,555,046 in view of US 2008/0153792-A1 06-2008.

However, the ‘792 publication teaches on [0062]-[0063] and [0044] the treatment of inflammatory condition such as lung conditions, cystic fibrosis, acute asthma, chronic asthma with 17α-ethynylandrost-5-ene-3β,7β,17β -triol (instant claims 12,13). Regarding instant claims 25 and 26, the ‘792 publication teaches on [0002], [0023] and [0044] the treatment of condition such as lung conditions, cystic fibrosis, acute asthma, chronic asthma with 17α-ethynylandrost-5-ene-3β,7β,17β -triol There would have been a reasonable expectation of success given the similar purposes of the references. 4.Claims 12, 15, 17, 18, 20, 43-46 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 9,314,471 in view of US 2008/0153792-A1.
