Office Action

§DP
DETAILED ACTION Claims 1-13 are pending. 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 . Priority The instant application filed 8/1/2023 is a Continuation of 18011084, filed 12/16/2022, now U.S. Patent 11,767,311. 18011084 is a National Stage entry of PCT/KR2021/007572, International Filing Date of 6/16/2021, and claims foreign priority to 10-2020-0073900, filed 6/17/2020. Information Disclosure Statement The Information Disclosure Statements (IDS) submitted on 8/11/2023 and 1/24/2024 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the Information Disclosure Statements are being considered by the Examiner. 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. U.S. Patent No. 11,767,311 Claims 1-13 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims of U.S. Patent No. 11,767,311. Although the claims at issue are not identical, they are not patentably distinct from each other because the ‘311 patent is directed to the same compounds for the same use, claims 1-8 are identical compounds and claim 9 states, “[a] pharmaceutical composition for preventing or treating gastrointestinal ulcers, gastrointestinal inflammatory diseases, or gastric acid-related diseases, comprising the compound according to any one of claims 1 to 8 or the pharmaceutically acceptable salt thereof, wherein the gastrointestinal ulcer, gastrointestinal inflammatory disease or gastric acid-related disease is any one or more selected from the group consisting of peptic ulcer, gastric ulcer, duodenal ulcer, NSAID-induced ulcer, acute stress ulcer, Zollinger-Ellison syndrome, Helicobacter pylori infection, gastritis, erosive esophagitis, non-erosive esophagitis, reflux esophagitis, inflammatory bowel disease, symptomatic gastroesophageal reflux disease (symptomatic GERD), functional dyspepsia, gastric cancer, gastric MALT lymphoma, hyperacidity, and upper gastrointestinal hemorrhage due to invasive stress.” Given the instant claims are directed to a method of treating gastrointestinal ulcers, gastrointestinal inflammatory diseases, or gastric acid-related diseases, the method comprising administering to a subject in need a therapeutically effective amount of a compound. Given the compounds are the same, the claims are anticipatory. Copending Application No. 18710749 Claims 1-13 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 10-11 of copending Application No. 18710749 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because ‘749 is directed to an anticipatory compound for treating gastrointestinal ulcers, thereby anticipating the instant claims. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Copending Application No. 18720436 Claims 1-13 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 11-12 of copending Application No. 18720436 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because ‘436 is directed to an anticipatory compound for treating gastrointestinal ulcers, thereby anticipating the instant claims. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Copending Application No. 18719710 Claims 1-13 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 25-26 of copending Application No. 18719710 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because ‘710 is directed to an anticipatory compound for treating gastrointestinal ulcers, thereby anticipating the instant claims. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Conclusion No claims allowed.
