Office Action

§102
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 . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Mazaki et al (US 2022/0169193). Re Claim 1; Mazaki discloses a vehicle power supply system that supplies electric power to a load mounted on a vehicle, (Fig. 26) comprising: a main power supply source (801); a sub-power supply source (802); a main power distribution control unit (ESI and ES2) that distributes and supplies electric power of the main power supply source (801) to a plurality of first loads (21, 31, 32); and a sub-power distribution control unit (ES4, ES3) that distributes and supplies electric power of the sub-power supply source to a plurality of second loads (22, 34, 33), the sub-power distribution control unit being connected to the main power distribution control unit so as to be able to supply the electric power of the sub-power supply source via a switch (152, 153), wherein the switch is controlled to a disconnected state when in a first state in which power supply from the sub-power supply source to the second loads is possible. (Par 0191-2) Re Claim 2; Mazaki discloses wherein the switch is controlled to a conductive state when in a second state in which the power supply from the sub-power supply source to the second loads is impossible. (Fig. 26) Re Claim 3; Mazaki discloses wherein the switch is controlled to a conductive state when in a third state in which the main power supply source is backed up by the sub-power supply source. (Fig. 26) Claim(s) 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hakushima et al (US 2023/0085180). Re Claim 1; Hakushima discloses a vehicle power supply system that supplies electric power to a load mounted on a vehicle, (Fig. 1) comprising: a main power supply source (10); a sub-power supply source (20); a main power distribution control unit (110) that distributes and supplies electric power of the main power supply source (10) to a plurality of first loads (101, 102); and a sub-power distribution control unit (120) that distributes and supplies electric power of the sub-power supply source to a plurality of second loads (103, Par 0024), the sub-power distribution control unit being connected to the main power distribution control unit so as to be able to supply the electric power of the sub-power supply source via a switch (41, Fig. 1), wherein the switch is controlled to a disconnected state when in a first state in which power supply from the sub-power supply source to the second loads is possible. (Fig. 1) Re Claim 2; Mazaki discloses wherein the switch is controlled to a conductive state when in a second state in which the power supply from the sub-power supply source to the second loads is impossible. (Fig. 2) Re Claim 3; Mazaki discloses wherein the switch is controlled to a conductive state when in a third state in which the main power supply source is backed up by the sub-power supply source.
