Office Action

§103
DETAILED ACTION Status of the Claims In the communication dated December 26, 2025, claims 1, 4-9, 15-17, 20-21 and 24-31 are pending. Claims 1, 4, 9, and 17 are amended, claims 24-31 are newly added, claims 2-3, 10-11, 18-19 and 22-23 are presently cancelled and claims 12-14 are previously cancelled. Response to Arguments The applicant argues that Kim1 does not switch M1 on within a preset time period when the charging power is less than a preset power threshold to bypass the rectifier circuit so that an input current cannot enter a direct bus (see pages 14-17). It should be noted that “so that an input current cannot enter a direct bus” is not included in the claim language. Kim1 discloses the rectifier circuit 4 detailed in at least FIG. 5. AS illustrated, the transistors M1-M4 are adjusted to allow current to flow. When more power is needed, the impedance of the transistors is reduced effectively allowing the current to bypass rectification. The applicant argues that obtaining the preset time period based on a difference between the charging power and the preset threshold, wherein the preset time period is directly proportional to the difference is not disclosed by Kim1 (see pages 17-19 of the applicant remarks. However, in FIG. 7 of Kim1, impedance is reduced when the gate signal is on and FIG. 8 illustrates that when the turn on time is low (T1 is the turn on time and T being the period),the impedance is high. When the turn-on time is high, the impedance is low. Thus, when more power is needed (the difference is high), the impedance will be low and the turn-on time will be high. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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, 4-9, 15-17, 20-21 and 24-31 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al.

Kim2 discloses that the rectifier (320/321) rectifies an alternating current into a direct current (¶14 - rectifier circuit 321 receives AC power) and supplying the direct current to a charging control circuit (¶14 – the rectifier outputs DC power).

Kim1 does not explicitly teach that the receive coil is configured to output an alternating current; the matching circuit performs matching on the alternating current and supply the alternating current; the rectifier circuit is configured to receive the alternating current from the matching circuit and rectify the alternating current into a direct current and supply the direct current to a charging control circuit. Kim2 discloses that the receive coil (FIG. 3B) is configured to output an alternating current (¶14 – resonant circuit outputs AC power); the matching circuit (312) performs matching on the alternating current and supply the alternating current (¶14 – because the rectifier circuit 321 receives AC power it follows that the matching circuit outputs AC power); the rectifier circuit (320/321) is configured to receive the alternating current from the matching circuit (¶14 - because the rectifier circuit 321 receives AC power) and rectify the alternating current into a direct current (¶14) and supply the direct current to a charging control circuit (¶14 – the rectifier outputs DC power). It would be obvious to one of ordinary skill in the art to provide an AC power, as taught by Kim2, to be converted to a DC/DC voltage by the rectifier of Kim1, as an AC current is commonly used to transmit to a receiver. Regarding claim 20. Kim1 discloses that the rectifier circuit (4) comprises at least one bridge arm that comprises at least one diode (the FET’s M1-M4 include a diode), and wherein the first controllable switching transistor (M2) is connected in parallel to two ends of one diode of the at least one diode (FIG. 5; M2 – the switch is parallel to the diode); and wherein the controller (gate driver 41) is further configured to control the first controllable switching transistor to be switched on (¶50 - gate driver controls on/off) when the charging power is less than the preset power threshold to bypass the rectifier circuit to reduce the input impedance of the rectifier circuit (¶44/53 – parameter setting unit 63 varies the on-time of the rectifier by comparing the current output power with the previous output power and adjusting the impedance). Regarding claim 21.

Regarding claim 24. Kim1 discloses that the controller is further configured to control the first controllable switching transistor to be switched on for the preset time period when the charging power is less than the preset power threshold (FIG. 7 – impedance is reduced when the gate signal is on; FIG. 8 illustrates that when the turn on time is low (T1 is the turn on time and T being the period), the impedance is high – when the turn-on time is high, the impedance is low, thus, when more power is needed (the difference is high), the impedance will be low and the turn-on time will be high). Regarding claim 25. Kim1 discloses that the rectifier circuit (4) further comprises a second controllable switching transistor (M1), wherein the first controllable switching transistor (M2) is located in a first lower-half bridge arm of the first bridge arm (M2/M4), wherein the second controllable switching transistor is located in a second lower-half bridge arm of the second bridge arm (M1/M3), and wherein the controller (41) is further configured to: control the first controllable switching transistor (M2) to be switched on for the preset time period when the charging power for the battery is less than the preset power threshold (FIG. 7; ¶60-61) and the alternating current received by the rectifier circuit is positive (FIG. 5 – connected to the positive output of the external matching element 3) (¶55- M1 and M2 are the active elements); and control the second controllable switching transistor (M1) to be switched on for the preset time period when the charging power for the battery is less than the preset power threshold (FIG. 7; ¶60-61) and the alternating current received by the rectifier circuit is negative (FIG. 5 – connected to the negative output of the external matching element 3) (¶55- M1 and M2 are the active elements). NOTE: the claim language includes conditional language (“when”) thus the device may be greater than the present power threshold and, thus, because the condition required in the claim does not occur, the claim limitations are met. Regarding claim 26. Kim1 discloses that the rectifier circuit (4) is a full-bridge rectifier circuit (4) (¶79 – FETs connected in the form of a bridge) and further comprises a second controllable switching transistor (M1), a third controllable switching transistor (M4), and a fourth controllable switching transistor (M3), wherein the first controllable switching transistor (M2) is located in a lower-half bridge arm of the first bridge arm (M2/M4), wherein the second controllable switching transistor (M1) is located in a lower-half bridge arm of the second bridge arm (M1/M3), wherein the third controllable switching transistor (M4) is located in an upper-half bridge arm of the first bridge arm (M2/M4), wherein the fourth controllable switching transistor (M3) is located in an upper-half bridge arm of the second bridge arm (M1/M3), and wherein the controller is further configured to: when the charging power for the battery is less than the preset power threshold (FIG. 7; ¶60-61) and the alternating current received by the rectifier circuit is positive (FIG. 5 – connected to the positive output of the external matching element 3), control the second controllable switching transistor (M1) to be switched on (¶49-50 – gate driver controls on/off of the switch resistance), control the fourth controllable switching transistor (M3) to be switched off (¶49-50 – gate driver controls on/off of the switch resistance), control the first controllable switching transistor (M2) to be switched on for the preset time period (¶49-50 – gate driver controls on/off of the switch resistance), and control the third controllable switching transistor (M4) to be switched on until the alternating current received by the rectifier circuit becomes zero (to make the current received zero, if the switch is turned off then the impedance is raised such that the current becomes zero ¶53 – “The parameter setting unit 63 may vary the input impedance of the active rectifier 4 by adjusting the turn-on time, gate voltage and/or switch resistance of each of the FET switches included in the active rectifier 4.”); and when the charging power for the battery is less than the preset power threshold (FIG. 7; ¶60-61) and the alternating current received by the rectifier circuit is negative (FIG. 5 – connected to the negative output of the external matching element 3), control the third controllable switching transistor (M4) to be switched off (¶49-50 – gate driver controls on/off of the switch resistance), control the first controllable switching transistor (m2) to be switched on (¶49-50 – gate driver controls on/off of the switch resistance), control the second controllable switching transistor (M1) to be switched on for the preset time period (¶49-50 – gate driver controls on/off of the switch resistance), and control the fourth controllable switching transistor (m3) to be switched on until the alternating current received by the rectifier circuit becomes zero (to make the current received zero, if the switch is turned off then the impedance is raised such that the current becomes zero ¶53 – “The parameter setting unit 63 may vary the input impedance of the active rectifier 4 by adjusting the turn-on time, gate voltage and/or switch resistance of each of the FET switches included in the active rectifier 4.”). NOTE: the claim language includes conditional language (“when”) thus the device may be greater than the present power threshold and, thus, because the condition required in the claim does not occur, the claim limitations are met. Regarding claim 27. Kim1 discloses to the controller is further configured to obtain the charging power by obtaining a voltage and a charging current output by the rectifier circuit (204) calculate the charging power based on the direct-current bus voltage and the charging current (¶14 – “The output value may include an output voltage and an output current of the rectifier” - because the general equation for determining power is power = current x voltage, a person of ordinary skill in the art would understand that the charging power is determined using the voltage and current from the rectifier). Because Kim1 does not specify the type of voltage, Kim1 does not explicitly teach that the voltage is a direct-current bus voltage. Kim2 discloses that the output of the rectifier is a DC voltage as the output is sent to a DC/DC converter (FIG. 3a). It would be obvious to one of ordinary skill in the art to use a DC voltage, as taught by Kim2 to calculate the charging power, as taught by Kim1, to provide batteries with a compatible charging voltage as batteries are commonly charged with a DC voltage. Regarding claim 28. Kim1 does not explicitly teach that the controller is further configured to obtain the charging power directly from a charging control chip. Kim2 teaches that the controller (360) is further configured to obtain the charging power directly from a charging control chip (¶89 – controller includes a multi-chip package and the controller detects changes to provide adjustments). It would be obvious to one of ordinary skill in the art to provide the controller details of Kim2 to the controller of Kim1 to illustrate details of a controller that control the charging power of the system. Regarding claim 29. Kim1 discloses that the preset power threshold corresponds to a charging power at which the matching circuit operates at a rated power (¶53 – the rectifier is operated at a maximum power, thus, the amount of power received from the matching circuit 3 is the maximum power that can safely be delivered to the rectifier 4). Regarding claim 30. Kim1 discloses that the preset time period increases as the charging power decreases (when the charging power decreases, the difference between the charging power and the power threshold increases, thus decreasing the resistance – as illustrated by FIG. 8B – when the resistance is decreased T1 increases). Regarding claim 31. Kim1 discloses repeatedly obtaining the charging power and repeatedly adjusting the preset time period in real time during the wirelessly charging the battery (¶53 – the current output power is compared with the previous output power thus obtaining the charging power is repeated; the input impedance is varied by adjusting the turn on time). Related Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Motoki et al. US5479336A discloses using a DC power-supply unit.
