Office Action

§112 §DP
DETAILED ACTION The amendment submitted on June 3, 2026 has been entered. Claims 1-17 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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Election/Restrictions Applicant’s election without traverse of Group I, drawn to a method of treating an indi-vidual suffering from multiple myeloma, leukemia or lymphoma, in the reply filed on June 3, 2026 is acknowledged. All of the pending claims correspond to the elected invention, with claims drawn to the other inventions having been cancelled. The requirement for a species election in the communication mailed on April 10, 2026 is hereby withdrawn. Applicant’s election thereof in the response submitted on June 3, 2026 is accordingly moot. Claim Objections Claim 1 is objected to because of the following informality: The phrase “to an individual in need thereof” should be inserted after the word “administering.” Appropriate correction is required. Claim Rejections – 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claim 11 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. The phrase “said orally administering” lacks antecedent basis. See MPEP1 2173.05(e) (lack of antecedent basis). It appears to be applicant’s intention that claim 11 should depend from claim 10 (not claim 1). 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 1-17 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,066,410 B2. Although the claims at issue are not identical, they are not patentably distinct from each other. The claims of the ‘410 Patent (cited in applicant’s IDS2) are drawn to the same compounds of the instant claims, as well as pharmaceutical compositions thereof. Compare, for example, Formula I and Formula II of the instant claims with the corresponding compounds defined in claims 1-2 of the ‘410 Patent. Although the ‘410 Patent does not specifically claim a method of administering the compounds to treat multiple myeloma, leukemia or lymphoma, such a method would have been prima facie obvious over the utility disclosed in the Patent (see, e.g., col. 20, ll. 52-58). The instant claims are therefore not patentably distinct from the claims of the ‘410 Patent. Claims 1-15 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-14 of U.S. Patent No. 11,987,583 B2. Although the claims at issue are not identical, they are not patentably distinct from each other. Claim 1 of the ‘583 Patent, of which the present application is a divisional, is directed to a method of treating multiple myeloma comprising administering a pharmaceutical composition comprising a therapeutically effective amount of the same compounds of Formula I as defined in the instant claims. At least claim 1 of the ’583 Patent therefore anticipates instant claim 1. Claim 13 of the ‘583 Patent is drawn to the same compound of instant claim 9, so at least instant claim 9 is anticipated by claim 13 of the ‘583 Patent. Claims 14-15 of the ‘583 Patent are drawn to oral administration and therefore anticipate at least instant claims 10-11.
