Office Action

§101 §DP
DETAILED ACTION Claims 47-66 are pending. Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Double Patenting (Statutory) 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 47-66 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-20 of prior U.S. Patent No. 12048769. This is a statutory double patenting rejection. Double Patenting (Nonstatutory) 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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The 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/process/file/efs/guidance/eTD-info-I.jsp. Claims 47-66 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 of U.S. Patent No. 8,722,085. Although the claims at issue are not identical, they are not patentably distinct from each other because the ‘085 discloses a method of administering bupropion and naltrexone and the claims in the application recited the same method of administering bupropion and naltrexone for reducing the risk of side effect of naltrexone and bupropion. Thus, the ‘085 patent is broad enough to encompass the method of reducing the risk of side effects of naltrexone and bupropion. The ‘085 and claims of the application possess significant overlapping scopes of inventions. Claims 47-66 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 of U.S. Patent No. 9,125,868. Although the claims at issue are not identical, they are not patentably distinct from each other because the ‘868 discloses a method of administering bupropion and naltrexone and the claims in the application recited the same method of administering bupropion and naltrexone for reducing the risk of side effect of naltrexone and bupropion. Thus, the ‘868 patent is broad enough to encompass the method of reducing the risk of side effects of naltrexone and bupropion. The ‘868 and claims of the application possess significant overlapping scopes of inventions. Claims 47-66 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 10,307,376. Although the claims at issue are not identical, they are not patentably distinct from each other because the ‘376 discloses a method of promoting weight loss by administering bupropion and naltrexone to an obese patient and the claims in the application recited the same method of administering bupropion and naltrexone for reducing the risk of side effect of naltrexone and bupropion to an obese individual (claim 60-62, 64, 66). Thus, the ‘376 patent is broad enough to encompass the method of reducing the risk of side effects of naltrexone and bupropion to an obese individual. The ‘376 and claims of the application possess significant overlapping scopes of inventions. Conclusion Claims 47-66 are rejected. No claims are allowed.
