Office Action

§DP
DETAILED ACTION This office action is in response to applicant’s filing dated May 14, 2024. 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 . Status of Claims Claims 58-98 are pending in the instant application. Acknowledgement is made of Applicant's amendments filed May 14, 2024. Acknowledgement is made of Applicant's cancelation of claims 1-57; and addition of new claims 58-98. Claims 58-98 are presently under examination. Priority The present application is a continuation of US Application No. 16/685,431 filed on November 15, 2019; which is a continuation of US Application No. 15/955,337 filed on April 17, 2018, which is a continuation of PCT/EP2016/076905 filed on November 8, 2016, which claims benefit of foreign priority to EP 15194297.6 filed on November 12, 2015. Information Disclosure Statement The information disclosure statements (IDS) submitted on May 14, 2024 and January 3, 2025 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner, except where marked with a strikethrough. Drawings Acknowledgement is made of the drawings received on January 31, 2024. These drawings are accepted. Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. In the instant case, the abstract contains language that can be implied, “The present invention provides” and “the present invention is concerned.” Applicant is reminded of the proper content of an abstract of the disclosure. In chemical patent abstracts for compounds or compositions, the general nature of the compound or composition should be given as well as its use, e.g., “The compounds are of the class of alkyl benzene sulfonyl ureas, useful as oral anti-diabetics.” Exemplification of a species could be illustrative of members of the class. For processes, the type of reaction, reagents and process conditions should be stated, generally illustrated by a single example unless variations are necessary. In the instant case, the instant claims are not directed to a genus of compounds but to a specific compound and the abstract should be illustrative of the claimed invention. Moreover, the abstract does not provide the use of the compound. 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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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/apply/applying-online/eterminal-disclaimer. Claims 58-98 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-47 of U.S. Patent No. 11,938,136 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because: The instant claims are directed to a pharmaceutical composition, comprising: 7-(4,7-diazaspiro[2.5]octan-7-yl)-2-(2,8-dimethylimidazo[1,2-b]pyridazin-6- yl)pyrido[1,2-a]pyrimidin-4-one or a pharmaceutically acceptable salt thereof; a stabilizer comprising disodium ethylenediaminetetraacetate; an antioxidant comprising ascorbic acid; and an acidifier comprising tartaric acid; wherein the pharmaceutical composition is in the form of a powder. The previously allowed claims are directed to a dry granulated powder blend for an oral solution, said dry granulated powder blend comprising 7-(4,7-diazaspiro[2.5]octan-7-yl)-2-(2,8-dimethylimidazo[1,2-b]pyridazin-6-yl)pyrido[1,2-a]pyrimidin-4-one or a pharmaceutically acceptable salt thereof; a stabilizer comprising disodium ethylenediaminetetraacetate; an antioxidant comprising ascorbic acid; and an acidifier comprising tartaric acid. The dried granulated powder blend of the previously allowed claims would anticipate the instantly claimed pharmaceutical powder composition. Moreover, the previously allowed claims encompass the same additional components as instantly claimed in the same amounts and ratios. Moreover, the instant claims and the copending claims encompass aqueous oral solution comprising the same components in the same amounts and ratios. Thus, the composition of the previously allowed claims would anticipate the composition of the instant claims. Conclusion Claims 58-98 are rejected. No claim is allowed.
