Office Action

§102
DETAILED ACTION This is a first action on the merits, in response to the claims received 11/28/2023. Claims 1 are pending for prosecution below. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) file on 11/28/2023 has been considered by the examiner. An initialed copy is attached herewith. 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 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jung et al, (Jung), (USNO.2018/0262027). As for claim 1, Jung discloses and shows in Figs. 1,6, and 12 a charging system including an automobile including a battery, and a power feed device for charging the battery, wherein: the automobile notifies the power feed device of a charging voltage suitable for charging the battery, prior to charging the battery (ref’s charging profile); the power feed device, upon receiving the charging voltage, raises voltage at an output end (via Buck/Boost converter) of the power feed device to a lower supply voltage of a rated output voltage of itself, and the charging voltage, and concurrently executes (via ref’s processor) a leakage check of checking for presence or absence of leakage between a positive electrode and a negative electrode of the output end, and starts power feed to the battery at the supply voltage when no leakage is detected by the leakage check; and the automobile monitors the voltage at the output end while the power feed device is executing the leakage check, to identify the supply voltage, and (1) charges the battery with electric power at the supply voltage when the supply voltage is equal to the charging voltage, and (2) raises the supply voltage to the charging voltage using a boost converter when the supply voltage is lower than the charging voltage, and charges the battery with electric power from the power feed device (par.[0039,0071-0077,0121,0167]).
