Office Action

§103
CTFR 18/620,114 CTFR 89701 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. This office action is in response to the filling of the Amendment on 03/05/2026. Double Patenting 08-33 AIA 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. 08-35 Claim s 1-3, 5, 6, 10-13 and 16 provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim s 1-2, 7, 8, 11, 12 and 16 of copending Application No. 18/899,228 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because : Regarding claim 1, the copending Application discloses a circuit comprising: a power electronics converter disposed in a vehicle, the power electronics converter to receive alternating current (AC) electrical power from an AC grid source and to provide AC electrical power to an AC load external to the vehicle; and an on-board charging module electrically connected to the power electronics converter and a battery disposed in the vehicle, the on-board charging module providing galvanic isolation between the battery and the AC load external to the vehicle, wherein the power electronics converter provides vehicle-to-load functionality by providing, to the AC load, AC electric power as an output of at least one of a 120 Vac output or a 240 Vac output (see claim 1) ; Regarding claim 2, the copending Application discloses the power electronics converter provides vehicle-to-load functionality based at least in part on an operating mode of the vehicle (see claim 2) ; Regarding claim 3, the copending Application discloses the power electronics converter comprises an AC-AC converter (see claim 1) ; Regarding claim 5, the copending Application discloses the power electronics converter comprises a relay matrix (see claim 7) ; Regarding claim 6, the copending Application discloses the power electronics converter comprises an AC-AC converter and a relay matrix (see claims 1 and 7) ; Regarding claim 10, the copending Application discloses the output is a split-phase output offering access to both 120 Vac and 240 Vac (see claim 8) ; Regarding claim 11, the copending Application discloses a vehicle comprising: a battery; a power electronics converter disposed in the vehicle, the power electronics converter to receive alternating current (AC) electrical power from an AC grid source and to provide AC electrical power to an AC load external to the vehicle and to the battery; and an on-board charging module electrically connected to the power electronics converter and the battery disposed in the vehicle, the on-board charging module providing galvanic isolation between the battery and the AC load external to the vehicle, wherein the power electronics converter provides vehicle-to-load functionality by providing, to the AC load, AC electric power as an output of at least one of a 120 Vac output or a 240 Vac output (see claim 11) ; Regarding claim 12, the copending Application discloses the power electronics converter provides vehicle-to-load functionality based at least in part on an operating mode of the vehicle (see claim 12) ; Regarding claim 13, the copending Application discloses the power electronics converter comprises an AC-AC converter (see claim 11) ; Regarding claim 16, the copending Application discloses the power electronics converter comprises an AC-AC converter and a relay matrix (see claims 11 and 16) .

Standards may be defined to identify particular plugs and connectors for each type of electrical power connection. The outlet panel 210 may be configured with a variety of outlets that provide power with different characterizing parameters) . Bhat does not expressly disclose an on-board charging module providing galvanic isolation between a battery of the vehicle and the AC load; and an AC-AC converter. Sahoo teaches (see figures 1-9) a power electronics converter (figure 4A, part 407) of a vehicle (paragraph [0038]; electrical system 101 may include various power conversion circuitry, described in greater detail below, for converting electrical energy received from one or more of the “sources” to a level suitable for another of the “sources.” For example, electrical system 101 may include circuitry for converting the voltage from AC grid 105 into a suitable voltage for charging high voltage battery 102 and/or low voltage battery 103.

Additionally, a non-isolated AC-AC converter 407 may be provided, which can convert the voltage appearing at the AC side of converter 406 to a suitable level for convenience outlet 404) . It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to configure the power electronics converter of Bhat with the on-board charging module and the AC-AC converter features as taught by Sahoo and obtain a method for providing vehicle-to-load functionality, the method comprising: configuring a plurality of switches and a plurality of relays of a power electronics converter of a vehicle based on an operating mode of the vehicle; and providing vehicle-to-load functionality by directing alternating current (AC) electrical power to an AC load electrically connected to the vehicle based on the configuration of the plurality of switches and the plurality of relays, wherein the vehicle comprises an on-board charging module providing galvanic isolation between a battery of the vehicle and the AC load, wherein the power electronics converter comprises an AC-AC converter and a relay matrix, the AC-AC converter comprising a first relay and a plurality of switches, the relay matrix comprising a plurality of relays, and wherein the first relay, the plurality of relays, and the plurality of switches are selectively enabled or disabled based on an input to the power electronics converter and based on whether the AC electric power is a 120 Vac output or a 240 Vac output, because it provides more isolation protection between power stages in order to obtain more efficient power converter with reduction in power device components, cost, and weight of the battery-based DC power system (paragraph [0003]) . Regarding claim 21, Bhat and Sahoo discloses everything claimed as applied above (see claim 20). Further, Bhat discloses (see figures 1-8) the converter (figures 1 and 2, part power electronics converter generated by 132 and converter stages inside of 160) comprises a first relay (figures 1 and 2, part 142) and a plurality of switches (figures 1 and 2, part plurality of switches inside of 132, 202 and 204) and the relay matrix (figures 1-3, part 322) comprises a plurality of relays (figures 1-3, part 322) (paragraph [0054]; A switch matrix 322 may include a plurality of contactor groups that may selectively couple one or more outlets with selected power connections 320.

However, Bhat does not expressly disclose the AC-AC converter. Sahoo teaches (see figures 1-9) the AC-AC converter (figure 4A, part 407) (paragraph [0046]; a battery based electrical system 400 using a high voltage battery 402. Electrical system 400 includes a single isolated AC-DC charger stage 406.

(US 2020/0122585), hereinafter Bhat, in view of Sahoo et al. (US 2023/0089299), hereinafter Sahoo, and further in view of Wade (US 6,515,883) . Regarding claim 4, Bhat and Sahoo teach everything claimed as applied above (see claim 3). Further, Bhat discloses (see figures 1-8) the converter (figures 1 and 2, part power electronics converter generated by 132 and converter stages inside of 160) . However, Bhat does not expressly disclose the AC-AC converter comprises a buck converter and a Ćuk converter. Sahoo teaches (see figures 1-9) the AC-AC converter (figure 4A, part 407) (paragraph [0046]; a battery based electrical system 400 using a high voltage battery 402. Electrical system 400 includes a single isolated AC-DC charger stage 406. Charger stage 406 may be a bidirectional charger, allowing for power delivery in either direction, i.e., either as an AC-DC converter in the forward direction or DC-AC converter in the reverse direction.

Additionally, a non-isolated AC-AC converter 407 may be provided, which can convert the voltage appearing at the AC side of converter 406 to a suitable level for convenience outlet 404) comprises a buck converter (figure 4A, part 407) (paragraph [0053]; AC converter 407 will perform a step-down) . It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to configure the power electronics converter of Bhat with the AC-AC converter features as taught by Sahoo, because it provides more efficient power converter with reduction in power device components, cost, and weight of the battery-based DC power system (paragraph [0003]) . Wade teaches (see figures 1-5) the AC-AC converter (figure 2) (column 7; lines 53-61; the converter 200 utilizes an AC input voltage source 202 and generates an output AC voltage for the load 228) comprises a buck converter (figure 2, part buck converter at 200) (column 2; lines 7-8; As will be recognized by those skilled in the art, this converter may be operated in a boost or buck fashion) and a Ćuk converter (figure 2, part Ćuk converter at 200) (column 8; lines 1-3; As will be recognized by those skilled in the art, this configuration approximates a Cuk converter topology with the addition of diode 206 and SCR 222) . It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to configure the combination of Bhat and Sahoo with the AC-AC converter features as taught by Wade and obtain the AC-AC converter comprises a buck converter and a Ćuk converter, because it improves power efficiency and reduced cost (column 8; lines 43-44) . Regarding claim 14, claim 4 has the same limitations, based on this is rejected for the same reasons . Response to Arguments 07-37 AIA Applicant's arguments filed 03/05/2026 have been fully considered but they are not persuasive. Applicant’s argues on pages 7-10 of the Applicant's Response (“Applicant submits that Bhat fails to disclose, teach, or suggest at least "the on board charging module providing galvanic isolation between the battery and the AC load external to the vehicle" as claimed. Regarding claim 11, Applicant submits that Bhat fails to disclose, teach, or suggest at least "the on board charging module providing galvanic isolation between the battery and the AC load external to the vehicle" as claimed… Applicant respectfully traverses this rejection for at least the reason that Bhat, Sahoo, and/or Wade, individually or together in any combination, fail to disclose, teach, or suggest all of the claimed features of claims 3, 4, 6-9, 13, 14, and 16-20”). The Examiner respectfully disagrees with Applicant’s arguments, because the new 103 rejection between Bhat and Sahoo (based on the new proposed amendment) meet with the claimed limitation. The primary reference Bhat discloses the circuit (figure 1) with the on-board charging module (figure 1, part on-board charging module generated by 132) (paragraph [0021]; an on-board power conversion module or charger 132. The charger 132 may condition the power supplied from the EVSE 138 to provide the proper voltage and current levels to the traction battery 124). Sahoo teaches the on-board charging module (figure 4A, part on-board charging module generated by 406; applicable to electric vehicle) providing galvanic isolation (figure 4A, part on-board charging module generated by 406) (paragraph [0046]; a battery based electrical system 400 using a high voltage battery 402. Electrical system 400 includes a single isolated AC-DC charger stage 406. Charger stage 406 may be a bidirectional charger, allowing for power delivery in either direction, i.e., either as an AC-DC converter in the forward direction or DC-AC converter in the reverse direction… Additionally, a non-isolated AC-AC converter 407 may be provided, which can convert the voltage appearing at the AC side of converter 406 to a suitable level for convenience outlet 404) between the battery (figure 4A, part 402) and the AC load external (figure 4A, part 404) to the vehicle (paragraph [0038]; electrical system 101 may include various power conversion circuitry, described in greater detail below, for converting electrical energy received from one or more of the “sources” to a level suitable for another of the “sources.” For example, electrical system 101 may include circuitry for converting the voltage from AC grid 105 into a suitable voltage for charging high voltage battery 102 and/or low voltage battery 103. This arrangement may be included in applications such as electric vehicles). It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to configure the on-board charging module of Bhat with the on-board charging module features as taught Sahoo and obtain a circuit comprising: a power electronics converter disposed in a vehicle, the power electronics converter to receive alternating current (AC) electrical power from an AC grid source and to provide AC electrical power to an AC load external to the vehicle; and an on-board charging module electrically connected to the power electronics converter and a battery disposed in the vehicle, the on-board charging module providing galvanic isolation between the battery and the AC load external to the vehicle, wherein the power electronics converter provides vehicle-to-load functionality by providing, to the AC load, AC electric power as an output of at least one of a 120 Vac output or a 240 Vac output, because it provides more isolation protection between power stages in order to obtain more efficient power converter with reduction in power device components, cost, and weight of the battery-based DC power system (paragraph [0003]). Therefore, the 103 combination between Bhat and Sahoo result in the claimed limitation .
