Office Action

§103
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 . Status of the Claims This Office Action is in response to Applicant's Restriction Requirement remarks filed on March 27, 2026. Claim(s) 1-3, 7-12, 14-16, 19, 23-28, 30, 33, 35, 37 are pending. Claim(s) 1, 2, 9, 12, 16, 23, 30, 33, 35, and 37 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant's election of Group I drawn to a compound of Formula I or II and election of species of [18F]TZ82112 (compound) without traverse of the restriction requirement in the reply is acknowledged. The requirement is deemed proper and is therefore made FINAL. Claim(s) 3, 7, 8, 10-11, 14-15, 19, 24, and 28 are examined herein insofar as they read on the elected invention and species. 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 claims at issue 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); and 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 a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO internet Web site contains terminal disclaimer forms which may be used. Please visit http://www.uspto.gov/forms/. The filing date of the application will determine what form 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 http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 3, 7, 8, 10-11, 14-15, 19, 24, and 28 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims ## of U.S. Patent No.10,676,467. Although the conflicting claims are not identical, they are not patentably distinct from each other. The instant claims are drawn to a compound of formula V. The patented claims are a compound of formula I. As can be seen in the side-by-side comparison, the patented claims embrace the instant claims. Instant Claims Patented Claims (US 10,676,46) PNG media_image1.png 142 305 media_image1.png Greyscale PNG media_image2.png 186 469 media_image2.png Greyscale PNG media_image3.png 274 642 media_image3.png Greyscale PNG media_image4.png 360 474 media_image4.png Greyscale Thus, the invention as a whole would have been anticipated in view of the patented claims. Claim Rejections - 35 USC § 103 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. 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. Claims 3, 7, 8, 10-11, 14-15, 19, 24, and 28 are rejected under 35 U.S.C. 103 as being unpatentable over Tu (US 2019/0002450) of record. Tu teaches compounds of formula I (claim 1; [0007]-[0010]): PNG media_image5.png 124 338 media_image5.png Greyscale PNG media_image6.png 778 482 media_image6.png Greyscale PNG media_image7.png 1004 388 media_image7.png Greyscale PNG media_image8.png 1012 488 media_image8.png Greyscale PNG media_image9.png 122 504 media_image9.png Greyscale Tu does not specifically exemplify a compound wherein R10 is F as required by the limitations of the elected species. It would been obvious to one of ordinary skill in the art at the time of filing of the invention to have known of the compounds of formula I as taught by Tu and envisioned the R10 as F. Tu teaches a generic group of compounds which embraces applicants’ claimed compounds as discussed above. The claims differ from the reference by reciting specific species and a more limited genus than the reference, particularly as it pertains to R10. However, 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 taught by the Tu, including those 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 compounds from the genus in the reference since such compounds would have been suggested by the reference 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). Thus, based on the foregoing reasons, the instant claims are deemed unpatentable over the cited reference. Conclusion Claims 3, 7, 8, 10-11, 14-15, 19, 24, and 28 are not allowed.
