Office Action

§112 §DP
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 . The compound of claims 2 and 3, namely, 2-chloro-N-(5-(2-(((1r,4r)-4- (dimethylamino)cyclohexyl)amino)-8-ethylquinazolin-6-yl)-6-methylpyridin-2- yl)benzenesulfonamide has the following structural formula PNG media_image1.png 200 400 media_image1.png Greyscale . 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. Claim 2 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. The pharmaceutical composition in claim 2 should necessarily have “an effective amount” of the compound present for it to work. Insertion of the phrase “an effective amount of ” following “comprising” is suggested. 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 2-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-24 of U.S. Patent No. 10,745,379. Claims 2-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-24 of U.S. Patent No. 10,961,218. Claims 2-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-22 of U.S. Patent No. 11,634,403. Claims 2-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-21 of U.S. Patent No. 12/071,424. Claims 2-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of U.S. Patent No. 11,649,224. Claims 2-3 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-13 and 16-18 of U.S. Patent No. 11,021,466. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims are embraced by the patented claims. The reference patents are directed to compounds, pharmaceutical compositions and methods of use of compounds which embraces applicants’ instantly claimed compounds, pharmaceutical compositions and methods of use. The instant claims differ from the reference claims by reciting a specific species of the reference patent claims. It would have been obvious to one having ordinary skill in the art at the time of the invention to select any of the species of the genus claimed by the reference patents, including the one instantly claimed, because the skilled chemist would have the reasonable expectation that any of the species of the genus would have similar properties and, thus, the same use as taught for the genus as a whole. One of ordinary skill in the art would have been motivated to select the claimed compound from the genus in the reference claims since such compound would have been suggested by the references as a whole. It has been held that a prior art disclosed genus of useful compounds is sufficient to render prima facie obvious a species falling within a genus. In re Susi, 440 F.2d 442, 169 USPQ 423, 425 (CCPA 1971), followed by the Federal Circuit in Merck & Co. v. Biocraft Laboratories, 847 F.2d 804, 10 USPQ 2d 1843, 1846 (Fed. Cir. 1989). Claim 3 is not patentably distinct from the reference claims because it simply claims the use disclosed in the specification of the reference patents as a method of use claim. See Pfizer, 518 F.3d at 1363; Geneva, 349 F.3d at 1385. See Sun Pharmaceutical Industries v. Eli Lilly and Co., 611 F.3d 1381, 1389 (2010). In AbbVie Inc. v. Kennedy Institute of Rheumatology Trust, 764 F.3d 1366, 112 USPQ2d 1001 (Fed. Cir. 2014), the court explained that it is also proper to look at the disclosed utility in the reference disclosure to determine the overall question of obviousness in a nonstatutory double patenting context. See also Pfizer, Inc. v. Teva Pharm. USA, Inc., 518 F.3d 1353, 86 USPQ2d 1001 (Fed. Cir. 2008); Geneva Pharmaceuticals Inc. v. GlaxoSmithKline PLC, 349 F3d 1373, 1385-86, 68 USPQ2d 1865, 1875 (Fed. Cir. 2003). Any inquiry concerning this communication or earlier communications from the examiner should be directed to BRUCK KIFLE whose telephone number is (571)272-0668.
