Office Action

§DOUBLEPATENT
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 . Double Patenting Rejections -Withdrawn Applicant's arguments filed 08/15/2025 have been fully considered and they are not persuasive. Terminal disclaimers filed by the Applicant overcomes the double patenting rejections for the rejection of instant claims over U.S. Patent No. 10588862 claims and U.S. Patent No. 10945958.claims. The rejection of Claims 1-10,12-14,16-20 on the ground of nonstatutory double patenting as being unpatentable over claim of U.S. Patent No. 10588862 claims and U.S. Patent No. 10945958 claims are withdrawn. Applicant filed respective terminal disclaimers which have been accepted by the USPTO as clearing/removing the two Obviousness type double patenting rejections of record Double Patenting Rejection -New 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. New Obviousness type Double Patenting rejection Claims 1-7,9-10,13,17-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 of U.S. Patent No. 11612567. Although the claims at issue are not identical, they are not patentably distinct from each other because both instant claims and US Patent 11612567 claim sets make claim to an implant comprising the steroid dimer having the dimers: PNG media_image1.png 35 237 media_image1.png Greyscale PNG media_image2.png 94 587 media_image2.png Greyscale Wherein the implant comprises at least 60% by weight of the steroid formulas above(instant claims 1) in comparison to USPN ‘567 claim 1 reciting : PNG media_image3.png 407 419 media_image3.png Greyscale Both instant claims and US patent ‘567 claims teach treating/administering the dimer to the eye. Thus, the claims of US patent ‘567 renders obviousness type double patenting over the instant claims. Claim Objection/Allowable Subject Matter Claims 8,11-12,14-15 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. Claim 16 is allowable.
