Office Action

§DP
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 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. Claims 2-9 and 11-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 4-7, 9-11, 13, 14, and 16 of U.S. Patent No. 12,362,779. Although the claims at issue are not identical, they are not patentably distinct from each other because many of the limitations of the pending claims are also in the claims of the patent. Regarding Claims 2 and 3, both the pending claim and claim 1 of the patent teach an antenna, transceiver, and first and second transistors. Claim 1 of the patent teaches third and fourth transistors, but that is taught in pending claim 3. The resistive element in pending claim 1 is taught in claim 4 of the patent. Regarding Claim 11, all elements of pending claim 11 are in claim 8 of the patent. Regarding Claim 17, all elements of pending claim 17 are in claim 13 of the patent. Claim 4 is taught in claim 8 of the patent. Claim 5 is taught in claim 8 of the patent. Claim 6 is taught in claim 4 of the patent. Claim 7 is taught in claim 5 of the patent. Claim 8 is taught in claim 6 of the patent. Claim 9 is taught in claim 7 of the patent. Claim 12 is taught in claim 14 of the patent. Claim 13 is taught in claim 13 of the patent. Claim 14 is taught in claim 13 of the patent. Claim 15 is taught in claim 9 of the patent. Claim 16 is taught in claim 16 of the patent. Claim 18 is taught in claim 9 of the patent. Claim 19 is taught in claim 10 of the patent. Claim 20 is taught in claim 11 of the patent. Response to Arguments Applicant's arguments filed 5/26/2026 have been fully considered but they are not persuasive. The Double Patenting rejection is maintained because despite the amendment, all of the key similarities between the pending claims and the claim of the patent stated above still exists.
