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 . Response to Amendment Applicant’s amendment to the claims filed August 4, 2026 has been entered. Claim 1 is currently amended and under examination. 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. Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,502,254. Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding claim 1, claim 1 of the ‘254 patent claims a method for manufacturing a transparent dental alignment device comprising 3D printing a dental alignment device using a raw material for forming transparent alignment devices; removing uncured resin and liquid from the dental alignment device; post-curing the dental alignment device; post heat treating the dental alignment device; cleaning the dental alignment device obtained in the step of post heat treating; wherein, removing the uncured resin and liquid is performed by spraying compressed air with a pressure of 5-12 bar into the device; the step of post curing is performed at a temperature of 60-90°C; the step of post heat treating is performed at a rate of less than 25°C/min, starting from a temperature of 60-90°C; and cleaning includes a solution washing step, a drying step for 5 minutes or more to allow the washing fluid to completely dry, and a water rinsing step. Claim 1 of the instant application is directed to “a whitening tray” while claim 1 of the ‘254 patent is directed to “a dental alignment device”. The structures associated with the different recitations are understood to overlap in scope. Further, to the extent the structures are possibly different, one having ordinary skill in the art would have found it prima facie obvious to have made a substantially similar transparent dental appliance, such as the claimed whitening tray, by the method set forth in the ‘254 patent in order to effectively 3D print a transparent raw material into a suitable and substantially similar dental appliance having a substantially similar shape and oral application. As to the different language associated with the post heat treating/cooling in the claims at a rate 25°C/min or less, the limitations are understood to be stating and suggesting substantially the same thing with somewhat different wording. Response to Arguments Applicant’s arguments filed August 4, 2026 have been fully considered and they are persuasive in view of the amendment to the claims. The previous objections, section 112b, and section 103 rejections have been withdrawn. There are no arguments of record traversing the double patenting rejection and the rejection is understood to remain applicable. 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.
