Office Action

§DOUBLEPATENT
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 . Status of the Application This Office Action is in response to applicant’s arguments filed on 6/24/26. Claims 3-4 have been cancelled. Claims 1-2, 5-20 are pending. Claims 1 and 18 have been amended. Claims 1-2, 5-20 are examined herein. The claim amendments have rendered the 103 rejection of the last Office Action moot, therefore hereby withdrawn. The terminal disclaimer filed on 6/24/26 disclaiming the terminal portion of any patent granted on this application, which would extend beyond the expiration date of Application No. 18/675,829; 19/339,926; and US Patent 12,029,721 have been reviewed and accepted. The terminal disclaimer has been recorded. The obviousness double patenting rejections are hereby withdrawn. Applicant’s arguments with regard to the remaining rejections have been fully repeated below for Applicant’s convenience. 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 1-2, 5-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over each the following: claims 1-8 of copending Application No. 17/429,259 (now US Patent 12,708,631) and claims 1-25 of copending Application No. 18/739,002. Although the claims at issue are not identical, they are not patentably distinct from each other because the referenced claims recite a method of treating migraine pain by administering a composition comprising CBD and THC in the same amounts and ratios. However, the referenced claims do not recite specifically pre-treating migraine pain. It would have been obvious to one of ordinary skill in the art to pre-treat migraine since the same composition is known to be useful for treating migraine pain. Therefore, one of ordinary skill in the art would have had a reasonable expectation of success in pre-treating migraine pain by administering a composition comprising CBD and THC. Response to Arguments Applicant argues that nothing in the referenced claims teach or suggests pre-treatment of migraine pain since the claims require administering the active agents after onset of symptoms. This is not persuasive because it would have been obvious to one of ordinary skill in the art to pre-treat migraine since the same composition is known to be useful for treating migraine pain. Therefore, one of ordinary skill in the art would have had a reasonable expectation of success in pre-treating migraine pain by administering a composition comprising CBD and THC. Conclusion 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.
