Office Action

§102 §103 §DOUBLEPATENT
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 . Detailed Action Response to Amendments The amendments made to the claims 02/05/2026 have been entered. Restriction/Species Election Claims 24-27, 30, and 36-38 remain withdrawn. Withdrawn Rejections In view of the amendments made to the claims, the 112(a) written description rejection, the 112(b) indefinite rejection, 102 and 103 rejections have been withdrawn. New Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1, 11-13, 15, 19, and 22 is/are rejected under 35 U.S.C. 102(a)(1) and (a)(2) as being anticipated by Hendricks (WO 2011/144585). Hendricks discloses a compound of the following structure on p. 253, example 225. Hendricks compound PNG media_image1.png 154 160 media_image1.png Greyscale The compound above embraces the limitations of claims 1, 11, 12, 13, and 15. Regarding claims 19 and 22, the claims are drawn to limitations that are properties of the claimed compound. Therefore, without data showing that opposite, the limitations are considered inherent properties of the compound and are also embraced by the disclosure of the compound above. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1, 11-13, 15, 18-19, and 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hendricks (Cited above). KSR Rationales The MPEP in section 2143, subsection I gives examples of Rationales for supporting a conclusion of obvious. These rationales are non-exhaustive and include (A) Combining prior art elements according to known methods to yield predictable results; (B) Simple substitution of one known element for another to obtain predictable results; (C) Use of known technique to improve similar devices (methods, or products) in the same way; (D) Applying a known technique to a known device (method, or product) ready for improvement to yield predictable results; (E) “Obvious to try” – choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success; (F) Known work in one field of endeavor may prompt variations of it for use in either the same field or a different one based on design incentives or other market forces if the variations are predictable to one of ordinary skill in the art; (G) Some teaching, suggestion, or motivation in the prior art that would have led one of ordinary skill to modify the prior art reference or to combine prior art reference teachings to arrive at the claimed invention. Discussion of Hendricks from the 102 rejection above is incorporated here. Regarding claim 18, which is drawn to a composition comprising the claimed compound and a pharmaceutically acceptable excipient, Hendricks on p. 101, l. 19-21 contemplates compositions comprising the compound of Hendricks with a conventional excipient. Hendricks states “A compound or compounds of the present invention, as well as their pharmaceutically useable salts, together with one or more conventional excipients, carriers, or diluents, may be placed into the form of a pharmaceutical compositions and unit dosages.” Therefore, it would have been prima facie obvious at the time of the effective filing date for one of ordinary skill in the art to have taken the compound of Hendricks and create a composition comprising the compound with a reasonable assumption of success. One of ordinary skill would find motivation in Hendricks which directly contemplates compositions comprising its compounds. New rejections necessitated by amendments Applicant has amended the claims to exclude art that was cited in the prior action. Further search identified new art that is applied to the newly amended claims. Maintained Double Patenting Rejections 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. Co-pending application 18/688,088 Claims 1, 3-6, 8-9, 11-19, and 22 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 137 of copending Application No. 18/688,088 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other. The reference claim is drawn to a method of treating a proliferative disease comprises of administering a compound of or a composition comprising Formula III shown below. Reference compound PNG media_image2.png 194 610 media_image2.png Greyscale The claim also specifies constituents which are all identical to the substituents claimed in instant claim 1. A sampling of the substituents is shown below. Instant claim PNG media_image3.png 334 616 media_image3.png Greyscale Reference claim PNG media_image4.png 345 626 media_image4.png Greyscale Additionally, the reference specification discloses the following compound 667 on p. 194. Reference compound PNG media_image5.png 108 450 media_image5.png Greyscale Compound 667 embraces all elements of claims 1, 3-6, and 8-9, 11-16 and is identical to compound 195 of instant table 1. Compound 195 PNG media_image6.png 110 534 media_image6.png Greyscale The reference claim also contemplate administration of a composition comprising the compounds above. Regarding claims 19 and 22, for similar reasoning discussed in the 103 rejection above, the compounds read on the limitations of instant claim 1 and would therefore also embrace the claim limitations of instant claims 19 and 22. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Response to Arguments Applicant has not traversed the non-statutory double patenting rejections in favor of keeping the rejection in abeyance until allowable subject matter has been identified. 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.
