Office Action

§102
DETAILED ACTION This is a first action on the merits, in response to the claims received 08/28/2023. Claims 1-5 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 8/28/2023,3/15/2024 has been considered by the examiner. An initialed copy is attached herewith. Claim Objections Claim 5, recites “the auxiliary machine” which lacks proper antecedent basis. Appropriate correction is required. 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) 1,2, and 5 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lin et al, (USNO.2016/0054390]). As for claim 1, Lin discloses and shows in Fig. 1 a battery management system, comprising: an acquisition section that acquires, in a case where a charging current flowing from a charger to a battery is measured by a current measurement device, a measurement value measured by the current measurement device; an estimation section that estimates a current value of the charging current by referring to a characteristic map (ref’s lookup table) based on a known value of a current flowing from the charger, the characteristic map indicating a characteristic of the battery; and a correction section (ref’s current correction module) that corrects an offset in the current measurement device based on the current value having been estimated and the measurement value (par.[0018-0028,0032-0033]). As for claim 2, Lin discloses and shows in Fig. 1 the characteristic map is a map indicating a relationship of the current value of the charging current with a terminal voltage of the battery, an ambient temperature of the battery, and a state of charge of the battery As for claim 5, Lin discloses and shows in Fig. 1 a vehicle, comprising: the battery and the auxiliary machine which are mounted in the vehicle; and the battery management system according to claim 4. Allowable Subject Matter Claims 3-4 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Claim 3: a current value calculation section that calculates the current value of the charging current based on the known value of the current flowing from the charger; and an average value calculation section that calculates an average value of a plurality of measurement values, wherein the correction section corrects the offset in the current measurement device in a case where a difference between the current value and the average value exceeds a predetermined range, the current value and the average value having been calculated, in combination with the remaining limitations of independent claims Contact Information Any inquiry concerning this communication or earlier communications from the examiner should be directed to ARUN C WILLIAMS whose telephone number is (571)272-9765.
