Office Action

§101 §DOUBLEPATENT
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 . DETAILED ACTION This office action is in response to applicant’s reply filed on August 29, 2025. Status of Claims Claims 21-40 are currently pending and are the subject of this office action. Claims 21-40 are presently under examination. Priority PNG media_image1.png 44 402 media_image1.png Greyscale Rejections and/or Objections and Response to Arguments Rejections and/or objections not reiterated from previous office actions are hereby withdrawn. The following rejections and/or objections are either reiterated (Maintained Rejections and/or Objections) or newly applied (New Rejections and/or Objections, Necessitated by Amendment or New Rejections and/or Objections not Necessitated by Amendment). They constitute the complete set presently being applied to the instant application. Responses to Applicant’s arguments have been addressed immediately after the corresponding rejections, or in the section: Withdrawn Rejections and/or Objections, if the rejection was withdrawn. Claim Objections (Maintained Objection) Applicant is advised that should claim 25 be found allowable, claims 27 and 29 will be objected to under 37 CFR 1.75 as being a substantial duplicate thereof. When two claims in an application are duplicates or else are so close in content that they both cover the same thing, despite a slight difference in wording, it is proper after allowing one claim to object to the other as being a substantial duplicate of the allowed claim. See MPEP § 608.01(m). Response to Applicant’s arguments related to the above rejection Applicant's arguments have been fully considered but are not persuasive. Applicant argues that: Claims 25, 27, and 29 have different recitations by virtue of their differing dependencies. Claim 25 depends directly from claim 21. Claim 27 depends from claim 21 via claim 26 as an intermediate claim. Claim 29 depends from claim 21 via claim 28 as an intermediate claim. Examiner’s response: MPEP § 608.01(m) states: “When two claims in an application comply with the requirements of 35 U.S.C. 112(d) but are duplicates, or else are so close in content that they both cover the same thing, despite a slight difference in wording, it is proper after allowing one claim to object to the other claim under 37 CFR 1.75 as being a substantial duplicate of the allowed claim.” In other words, even though claims 25, 27 and 29 have different dependencies, they recite the exact same limitations, so they are not considered to be different. Double Patenting (Maintained Rejection) A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention, so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 21, 22, 23, 24, 25, 26, 27, 29, 34, 35, 36, 37, 38 and 39 stand rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1, 2, 3, 4, 5, 7, 7, 7, 8, 10, 13, 15, 16 and 19 respectively of prior U.S. Patent No. 11,813,239. This is a statutory double patenting rejection. Response to Applicant’s arguments related to the above rejection Applicant's arguments have been fully considered but are not persuasive. Applicant argues that: Claim 1 of US Patent 11,813,239 differs from claim 21 of the present application at least insofar as claim 1 of US Patent 11,813,239 recites “administering a succinate dehydrogenase inhibitor to the subject starting at least 90 minutes after a cardiac event,” whereas claim 21 of the present application merely recites “administering a succinate dehydrogenase inhibitor to the subject at least 90 minutes after a cardiac event” Examiner’s response: While the wording of the claims is slightly different, the claims prima facie encompasses the same method. Even though the instant application does not explicitly use the word starting, the fact is that it is implicit in the instant claims. In other words, the instant claims imply that the administration of the succinate dehydrogenase inhibitor cannot start before 90 minutes after a cardiac event, while the US 11,813,239 also states that the administration of the succinate dehydrogenase inhibitor cannot start before 90 minutes after a cardiac event, or in other words, both, the instant application and the ‘239 patent claim that the administration of succinate dehydrogenase inhibitor can start at least 90 minutes after a cardiac event. Double Patenting (Maintained Rejection). 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 28, 30-33 and 40 stand rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. 11,813,239. Although the claims at issue are not identical, they are not patentably distinct from each other because both claim the treatment of cardiac events comprising the administration of a succinate hydrogenase inhibitor. Response to Applicant’s arguments related to the above rejection Applicant's arguments have been fully considered but are not persuasive. Applicant argues that: Applicant filed a Terminal Disclaimer Examiner’s response: The Terminal Disclaimer was disapproved (see Terminal Disclaimer Review Decision dated 09/02/2025). Conclusion No claims are allowed. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
