Office Action

§101 §DOUBLEPATENT §DP
DETAILED ACTION The preliminary amendment submitted on October 29, 2024 has been entered. Claims 1-22 are pending in the application and are rejected for the reasons set forth below. No claim is allowed. 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 . Claim Rejections – 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufac-ture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claim 21 is rejected under 35 U.S.C. 101 as claiming the same invention as that of claim 1 of prior U.S. Patent No. 12,102,606 B2. This is a statutory double patenting rejection. Even though instant claim 21 is written in dependent form, it is nevertheless of identical scope to claim 1 of the ‘606 Patent. 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). This rejection can be overcome by canceling or amending the claim that is directed to the same invention so it is no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. 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 possi-ble 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 provi-sions 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 accompa-nied 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 1-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. 11,660,273 B2. Although the claims at issue are not identical, they are not patentably distinct from each other. Claim 1 of the ‘273 Patent is essentially the same as instant claim 1, except the Patent requires a “daily dose of the (S)-bupropion is about 60 mg to about 120 mg.” On the other hand, the instant claims require that the dose “is about 100 mg to about 300 mg” (see claim 1) or “about 120 mg to about 210 mg” (see claim 21). In situations like this, where “where the claimed ranges ‘overlap or lie inside ranges disclosed by the prior art’ a prima facie case of obviousness exists.” See MPEP 2144.05. The examiner therefore concludes that the instant claims are prima facie obvious over the claims of the ‘273 Patent. Claims 1-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. 11,660,274 B2. Although the claims at issue are not identical, they are not patentably distinct from each other for substantially the same reasons discussed above. Claims 1-20 and 22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. 12,102,606 B2. Although the claims at issue are not identical, they are not patentably distinct from each other for the same reasons discussed above. Claims 1-22 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 of copending Application No. 18/813,008 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other. Although the claims of the ‘008 Application do not specify any particular dosage amount, the subject matter of the instant claims would have been apparent over the disclosure in the specification of the ‘008 Application at pp. 6-7. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-22 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-21 of copending Application No. 18/650,022 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the ranges of dosage amount overlap. Compare, for example, claims 15-17 of the ‘022 Application with the corresponding dosage amounts in the instant claims. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
