Office Action

§103
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 § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1 – 6 and 8-16 are rejected under 35 U.S.C. 103 as being unpatentable over Shibuya (US 6140928) in view of Joo (US 20200136500). Regarding claim 1, Shibuya teaches an apparatus for controlling current consumption of a battery management system (BMS) managing a battery pack (figure 1 shows an apparatus for controlling a current consumption, item 6 interpreted as an integrated circuit (IC) for measuring the remaining battery capacity of a battery management system, interpreted as microprocessor item 5) the apparatus comprising: an input unit including a logic element (figure 2 item 60 shows an input unit including a logic element, interpreted as a logical data distribution circuit) to which a charger connection signal and an always constant power source off signal are input (column 8 lines 56 – column 9 lines 11 teaches wherein a charger connection signal is input. Column 8 lines 35 – 56 teaches wherein a constant power signal is input) an operation unit including a control circuit (figure 2 shows an operation unit IC item 6 including a plurality of control units including a current measuring circuit item 10, overcurrent measuring circuit item 20, voltage measuring circuit item 30, driver circuit item 40, power switch circuit item 50, logical data distribution item 60 and voltage detection circuit 1 and 2 items 70 and 80) , wherein the control circuit includes: a plurality of switches (figures 3, 4, and 5 show a plurality of switches); a plurality of operational amplifiers (figures 3, 4, 5 and 7 show a plurality of operational amplifiers); and a plurality of resistance elements (figures 3, 4, and 5 show a plurality of resistance elements). Shibuya does not explicitly teach wherein the operation unit is configured to generate a current consumption control signal for at least one component in the BMS according to an output of the logic element and an output voltage of the battery pack ([0066]-[0067] discloses wherein a current control signal is generated, interpreted as a signal corresponding to a current consumption to control a switching frequency of FETs and an output voltage). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Shibuya reference with the charging system of the Joo reference so that the power-on time of an electronic device is shortened. The suggestion/motivation for combination can be found in the Joo reference in [0005] wherein the power-on time of an electronic device is shortened.

Shibuya does not explicitly teach a driving voltage to output a micro controller unit (MCU) alarm signal. Joo teaches a driving voltage to output a micro controller unit (MCU) alarm signal (paragraph [0070] discloses wherein an alarm signal from the control circuit includes an LED provided on a display). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Shibuya reference with the charging system of the Joo reference so that the power-on time of an electronic device is shortened. The suggestion/motivation for combination can be found in the Joo reference in [0005] wherein the power-on time of an electronic device is shortened.

Shibuya does not explicitly teach wherein this signal is a current consumption signal Joo teaches wherein the signal is a current consumption signal ([0066]-[0067] discloses wherein a current control signal is generated, interpreted as a signal corresponding to a current consumption to control a switching frequency of FETs and an output voltage). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Shibuya reference with the charging system of the Joo reference so that the power-on time of an electronic device is shortened. The suggestion/motivation for combination can be found in the Joo reference in [0005] wherein the power-on time of an electronic device is shortened. Regarding claim 6, Shibuya teaches the apparatus of claim 1, wherein the at least one component in the BMS includes a micro controller unit (MCU) and a current supply device (column 6 lines 66 – column 7 line 9 discloses a microcontroller as a microprocessor 5.

Regarding claim 12, Shibuya teaches a battery management apparatus managing a battery pack (figure 1 shows an apparatus for controlling a current consumption, item 6 interpreted as an integrated circuit (IC) for measuring the remaining battery capacity of a battery management system, interpreted as microprocessor item 5), the battery management apparatus comprising: a current consumption control circuit including: a logic element (figure 2 item 60 shows an input unit including a logic element, interpreted as a logical data distribution circuit) to which a charger connection signal and an always constant power source off signal are input (column 8 lines 56 – column 9 lines 11 teaches wherein a charger connection signal is input.

Shibuya does not explicitly teach a driving voltage to output a micro controller unit (MCU) alarm signal. Joo teaches a driving voltage to output a micro controller unit (MCU) alarm signal (paragraph [0070] discloses wherein an alarm signal from the control circuit includes an LED provided on a display). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Shibuya reference with the charging system of the Joo reference so that the power-on time of an electronic device is shortened. The suggestion/motivation for combination can be found in the Joo reference in [0005] wherein the power-on time of an electronic device is shortened.

Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Shibuya (US 6140928) in view of Joo (US 20200136500) as applied to claim 1 and in further view of Perelle (US 20020195994) Regarding claim 7, Shibuya and Joo teach the apparatus of claim 1, but does not explicitly teach wherein the logic element is an AND gate. Perelle teaches wherein the logic element is an AND gate (figure 1 item 13 [0045] discloses wherein the logic element used within the system is an AND gate). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of the Shibuya and Joo reference with the gate system of the Perelle reference so that the current does not exceed a maximum threshold. The suggestion/motivation for combination can be found in the Perelle reference in paragraph wherein [0046] wherein the AND gate controls the flow of current so that a maximum threshold is not exceeded.
