Office Action

§102 §DP
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 The non-statutory 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 non-statutory 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 non-statutory 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 non-statutory 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 e-Terminal Disclaimer may be filled out completely online using web-screens. An e-Terminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about e-Terminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 13-22, 24, 25, 27, 29, 30 and 32 are rejected on the ground of non-statutory double patenting as being unpatentable over claims 1-12 of U.S. Patent No. 12,017,406 B2 in view of Zhao et al (WO 2018/022034 A1). Claims 1-12 of U.S. Patent No. 12,017,406 B2 recite a process of three-dimensional printing and a multi-fluid material for three-dimensional printing as claimed, except for the use of a fusing agent, which is taught by Zhao et al (see paragraphs [0021] (dispensing a fusing agent 32) and [0066] (phthalocyanine dye) of Zhao et al), and it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a fusing agent in the process and composition of claims 1-12 of U.S. Patent No. 12,017,406 B2 in view of Zhao et al in order to absorb applied electromagnetic radiation (see paragraph [0065] of Zhao et al). Response to Arguments Applicant’s arguments, see pages 10-21 of the reply, filed on 19 February 2026, with respect to claims 13-22, 24, 25, 27, 29, 30 and 32 under 35 U.S.C. §102(a)(1) and 35 U.S.C. §103 have been fully considered and are persuasive. The rejection of claims 13-22, 24, 25, 27, 29, 30 and 32 under 35 U.S.C. §102(a)(1) and 35 U.S.C. §103 has been withdrawn.
