Office Action

§112 §DOUBLEPATENT §DP
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 . Application Status The amendment filed on 4/20/2026 in response to the Non-Final rejection of 11/20/2025 is acknowledged and has been entered. Claims 3, 6, 9-13, 34, 37-45 and 59-61 are currently pending and under consideration. Rejections Maintained/Amended in view of Applicants Amendments: 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 3, 6, 9-13, 34 and 37-45 remain and new claims 59-61are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Independent claim 3 recites a compound having a structure of Formula (Ib): PNG media_image1.png 253 186 media_image1.png Greyscale and defines some, but not all, the variables. For example, X is not defined. Accordingly, the claims are indefinite. Regarding claims 6, 9 and 11, the claims appear to define X as being a piperdinyl. However, the piperdinyl lacks antecedent basis since claim 3 does not define X. 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 3, 6, 9-13, 34 and 37-45 remain and new claims 59-61 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-28 of copending Application No. 18/797,148 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the application overlap in scope with the bifunctional degraders of hematopoietic progenitor kinase and therapeutic uses thereof. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. In response to this rejection, Applicants contend that present claim 1 specify the LHM group as certain thalidomide moieties which are not claimed in the reference ‘148 application. These arguments have been carefully considered, but are not found persuasive. Claim 1 of the reference ‘148 application specifically makes reference to an “if” “then” statement PNG media_image2.png 183 612 media_image2.png Greyscale which insinuates that the thalidomide is encompassed within claim 1. Moreover, example compound 146, claimed in claim 28 of the reference ‘148 application has the structure PNG media_image3.png 213 323 media_image3.png Greyscale anticipates the instant claims. As such, the rejection is maintained. Rejections Withdrawn: The rejection of Claims 3, 6, 11-13, 15, 18, 34 and 37-45 on the ground of nonstatutory double patenting as being unpatentable over claims 1-40 of U.S. Patent No. 11739101B2 to Shunatona et al. (2023-08-29) is withdrawn in view of the approval of the Terminal Disclaimer. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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 nonprovisional extension fee (37 CFR 1.17(a)) 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.
