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 . Response to Arguments Applicant's arguments filed 2/11/2026 have been fully considered but they are not persuasive. The Applicant argues that Wiryadinata et al. U.S. PGPub 2014/0251965 does not disclose a "weld monitoring station... [that] receive[s] welding data from [a] welding device ..., determine[s] whether a threshold amount of time has passed... with no further welding data being received, and in response to determining the threshold amount of time has passed, send[s] a disable command to the welding device....". The Applicant asserts that Wiryadinata does not disclose specifying that the supervising circuitry 14 sends a disable command to the torch 16 after the delay period passes with no further actuation of the torch trigger. The Examiner respectfully disagrees. Wiryadinata states, “Entering the accessory mode may start a timer. The supervising circuitry determines (node 156) whether a weld signal is received prior to timer increasing to be substantially equal to the idle delay period. If the weld signal is received, the timer is reset (block 157) and the supervising circuitry re-enters the welding mode (block 152). If the weld signal is not received and the value of the timer is approximately equal to the idle delay period, then the supervising circuitry enters the monitoring mode (block 158). In the monitoring mode, the supervising circuitry may stop distributing the input power to all the power supplies except for the background power supply and certain power supplies (e.g., auxiliary power supply) selected by the operator to remain turned on. In some embodiments of the monitoring mode, the supervising circuitry may only distribute the input power as the background power to the background power supply. Entering the monitoring mode may restart the timer or compare the timer to a different period (e.g., monitoring delay period). The supervising circuitry may determine (node 160) whether a weld signal is received prior to the timer increasing to be substantially equal to the monitoring delay period. If the weld signal is received, the timer is reset (block 157) and the supervising circuitry re-enters the welding mode (block 152). If the weld signal is not received and the timer is substantially equal to the monitoring delay period, then the supervising circuitry may shut down (block 162) the welding power source or remain in monitoring mode (block 158) (¶39-40).” “In some embodiments of the monitoring modes 198 or 202, the supervising circuitry may transition to a shut down mode 204 at a time t.sub.10 after a monitoring delay 206 from entering the second monitoring mode 202. In the shut down mode 204, the supervising circuitry may turn off the background power supply to shut down the welding power source. In the shut down mode 204, the supervising circuitry may turn off each component of the welding power source. The monitoring delay 204 may be less than approximately 1, 5, 10, 15, 30, 60, or 90 minutes or more. The operator may adjust and/or eliminate the monitoring delay 204 via the operator interface. The duration of the monitoring delay 204 may also be defined in the supervising circuitry (¶47).” First, the Examiner notes that a torch does not have to be part of the "welding device" since the independent claims state a welding device "comprising a gas supply, a wire feeder, a welding torch, or a welding-type power supply". The Examiner asserts that Wiryadinata discloses circuitry configured to "determine whether a threshold amount of time (e.g. time t₁₀) has passed since an end of the first time period (e.g. monitoring delay) with no further welding data being received (i.e. no weld signal received) (e.g. ¶39-40), and in response to determining the threshold amount of time has passed, send a disable command (e.g. shutdown mode, turning off each component of the welding power source) to the welding device (e.g. ¶47). For at least these reasons, the rejection is maintained. 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 1-3, 5-10, 12-17, 19 and 20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4, 7-10, 14, 16 and 17 of U.S. Patent No. 12,042,887.
