Office Action

§DP
DETAILED ACTION Application filed 3/5/25 has been examined. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-20 are pending. Specification and drawings are accepted. IDSs have been considered. PTO-1449s are attached. Application is pending. 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 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 12,095,556. Although the claims at issue are not identical, they are not patentably distinct from each other. For example, claim 1 of the present application teaches a system for conditional forward error correction codeword decoding comprising: at least one processor; and memory including instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to: receive a conditional decoding window including a first codeword; decode the first codeword to determine a second codeword in the conditional decoding window; obtain a report that includes a codeword relevance bit for the second codeword; and upon a determination that the codeword relevance bit indicates that the second codeword is irrelevant, discard the second codeword without decoding the second codeword. Whereas claim 1 of U.S. patent ‘556 teaches a system for conditional forward error correction codeword decoding comprising: at least one processor; and memory including instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to: identify a first codeword in a network transmission; generate a conditional decoding window that begins with the first codeword; align the conditional decoding window with a frame of the network transmission; generate a report that includes an indication of relevance of the conditional decoding window to a network device; and transmit the conditional decoding window and the report to the network device. Both claims are directed towards conditional forward error correction decoding having a processor and a memory. A first codeword decoding window is either received or identified and a report is generated and used for further determination. The claims are obvious embodiments are each other and not patentably distinct. A terminal disclaimer would obviate the rejection. Claims 1-20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 2-21 of copending Application No. 18886820 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other. For example, claim 1 of the present application teaches a system for conditional forward error correction codeword decoding comprising: at least one processor; and memory including instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to: receive a conditional decoding window including a first codeword; decode the first codeword to determine a second codeword in the conditional decoding window; obtain a report that includes a codeword relevance bit for the second codeword; and upon a determination that the codeword relevance bit indicates that the second codeword is irrelevant, discard the second codeword without decoding the second codeword. Whereas claim 2 of U.S. patent application ‘820 teaches a system for conditional forward error correction codeword decoding comprising: at least one processor; and memory including instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to: generate a conditional decoding window that begins with a codeword in a network transmission; align the conditional decoding window with a frame of the network transmission; and transmit the conditional decoding window and an indication of relevance of the conditional decoding window to a network device. Therefore the claims are obvious variations of each other and not patentably distinct. A terminal disclaimer would obviate the rejection. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
