Office Action

§112 §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 . According to a preliminary amendment filed on Feb. 26, 2025, the applicants have canceled claims 3, 5-6, 8, 10-11, 13-15, 17, 20-23, 25-32, 34-36, 40-41, 44 and 50 and furthermore, have amended claims 1, 2, 7, 9, 12, 16, 18-19, 24, 33, 37, 39, 42-43, 45-47, 49 and 52. Claims 1-2, 4, 7, 9, 12, 16, 18-19, 24, 33, 37-39, 42-43, 45-49 and 51-52 are pending in the application. Claim Rejections - 35 USC § 112 4. 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 45 and 46 are 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. In claims 45 and 46, specific diseases associated with activity of KRAS, are not defined. 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, 4, 7, 9, 12, 16, 19, 24, 33, 37-39 and 42 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-30 of U.S. Patent No. 12, 441, 727. Although the claims at issue are not identical, they are not patentably distinct from each other because it would have been obvious to one skilled in the art to prepare instant compounds of formula (I) where variable X represents CR7 and pharmaceutical compositions comprising these compounds with reasonable expectation of success. Claims 1-2, 4, 7, 9, 12, 16, 19, 24, 33, 37-39, 42-43 and 45-49 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-34 of U.S. Patent No. 12, 600,717. Although the claims at issue are not identical, they are not patentably distinct from each other because it would have been obvious to one skilled in the art to prepare instant compounds of formula (I) where variable X represents CR7, pharmaceutical compositions comprising these compounds and methods of inhibiting KRAS activity and treating cancer with reasonable expectation of success. Allowable Subject Matter Claims 18 and 51-52 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The instant compounds of formula (I) are allowable over the prior art since they are neither disclosed nor obvious over the prior art. In the prior art, Bouillot (U.S. Patent 8,557,984, cited on applicant’s form 1449) discloses imidazoquinoline derivatives. The compounds disclosed in examples 211-214 (see co. 163) by Bouillot do anticipate the instant compounds. However, these compounds are excluded by a proviso since variable CY1 can’t represent 3,5-dimethylisoxazol-4-yl.
