Office Action

§102 §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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 2/3/2026 has been entered. Response to Amendment Claims 1-20 remain pending in the application. Response to Arguments Applicant's arguments filed 2/3/2026 have been fully considered but they are not persuasive. Applicant submits in the third paragraph on pages 11-12 and the first paragraph on page 14 of remarks that Gong merely describes separate entities, such as a main emergency power supply module and a first slave emergency power supply module that provide power to a power system when an AC grid is powered off. For example, with reference to FIGs. 3 and 4 of Gong, the vehicles in Gong provide power to the system, but not via a switching power supply, as claimed. See Gong, paragraphs [0056] and [0057]. Gong does not disclose or suggest a switching power supply that uses switches to stop discharging and conduct a path via another entity (e.g. the vehicle) to supply power to the load device. The examiner submits that the first switch corresponds to the switch next to the AC power grid 400 (Gong - Fig. 4) and the second switch corresponds to the switch next to AC/DC converter in slave emergency power module 201. The examiner submits that main emergency power supply module 100 in conjunction with the above described switches encompasses the claimed charging and discharging switching apparatus and method. Switches are controlled in a manner to provide power to the load either from main emergency power supply module 100 including , the AC power grid 400, or the vehicle in the slave emergency power module 201 (Gong ¶’s [14, 16]). The applicant submits on page 13, the emergency power supply device 300 of Gong does not form part of the path when switching power supply sources from the master emergency power supply module 100 to the first slave emergency power supply module for providing power to the power consumption system 500, and certainly does not do so via switches that are part of the emergency power supply device. This is contrast to the features of claim 1 of the charging and discharging switching apparatus including a first switch, a second switch, and the switching power supply for discharging and switching to form different paths via the first switch and second switch to the load device and vehicle via the controller, where the switching power supply serves as the power supply body during such a transfer. Instead, Gong is silent as to another entity serving as power supply body for their load device during transfer of power to their power consumption system. The examiner submits that claim language does not require the emergency power supply device 300 of Gong to form part of the path when switching power supply sources from the master emergency power supply module 100 to the first slave emergency power supply module for providing power to the power consumption system 500. The examiner interprets main emergency power supply module 100 along with switches A* and B* from the annotated figure as a power supply body, wherein paths are generated to the load either from main emergency power supply module 100, the AC power grid 400, or the vehicle in the slave emergency power module 201 (Gong ¶[14, 16, 57]).

Kempton teaches a transceiver (Fig. 3: microprocessor 304) connected to a controller (microcomputer 320), the controller configured to control the transceiver to send first indication information (¶0051 and ¶0092: EVSE attributes include vehicle authorizations and capabilities, which the examiner interprets as whether it is to be in a power supply state), wherein the first indication information indicates the vehicle to be switched to the power supply state (¶0025, 0052, and 0092 and Fig. 5: microcontroller 304 in EVSE and vehicle link (VL) in the EV communicate with each other to determine power flow). Gong and Kempton both teach vehicle to grid systems. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the instant application to incorporate the transceiver in the system of Kempton into the system of Gong to ensure a vehicle exists in the system to serve as a power source. Regarding claim 3, Gong in view of Kempton teaches the charging and discharging switching apparatus according to claim 2, wherein controlling the switching power supply to stop discharging (Gong - ¶0057 and Fig. 4) after the vehicle is switched to the power supply state (Kempton - ¶0052) comprises: after receiving first response information from the vehicle, control the switching power supply to stop discharging (Gong - ¶0057 and Fig. 4), wherein the first response information indicates that the vehicle has been switched to the power supply state (Kempton - ¶0052: 304 and VL are in mutual communication regarding reverse flow of power into EVSE 104 from EVE 102). Regarding claim 4, Gong teaches the charging and discharging switching apparatus according to claim 1. Gong does not explicitly teach wherein before controlling the switching power supply to discharge, the controller is further configured to: disconnect the first switch and the second switch. Smolenaers teaches switches being disconnected as part of a safety measure (¶0155 and 0181). Both Gong and Smolenaers teach power distributions systems involving electric vehicles. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the instant application to incorporate disconnecting switches leading to the battery in the system of Smolenaers into the system of Gong to help prevent inrush current or other wear and tear processes to the charging circuits. Regarding claim 5, Gong in view of Kempton teaches the charging and discharging switching apparatus according to claim 2, wherein the controller is further configured to: before turning on the first switch after the second condition is met, control the transceiver to send second indication information, wherein the second indication information indicates the vehicle to stop the power supply state (Kempton - ¶0052: 304 and VL are in mutual communication regarding reverse flow of power into EVSE 104 from EVE 102); and after the vehicle stops the power supply state, turn on the first switch (Gong - ¶0057 and Fig. 4).

Gong does not teach disconnecting first and second switches. Smolenaers teaches switches being disconnected as part of a safety measure (¶0155 and 0181). Both Gong and Smolenaers teach power distributions systems involving electric vehicles. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the instant application to incorporate disconnecting switches leading to the battery in the system of Smolenaers into the system of Gong to help prevent inrush current or other wear and tear processes to the charging circuits. Regarding claim 13, Gong teaches the method according to claim 12. Gong does not explicitly teach the method wherein before the discharging to the load device after the first condition is met, the method further comprises: sending, by the charging and discharging switching apparatus, first indication information, wherein the first indication information indicates the vehicle to be switched to the power supply state. Kempton teaches a transceiver (Fig. 3: microprocessor 304) connected to a controller (microcomputer 320), the controller configured to control the transceiver to send first indication information (¶0051 and ¶0092: EVSE attributes include vehicle authorizations and capabilities which the examiner interprets as whether it is to be in a power supply state), wherein the first indication information indicates the vehicle to be switched to the power supply state (¶0025, 0052, and 0092 and Fig. 5: microcontroller 304 in EVSE and vehicle link (VL) in the EV communicate with each other to determine power flow). Gong and Kempton both teach vehicle to grid systems. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the instant application to incorporate the transceiver in the system of Kempton into the system of Gong to ensure a vehicle exists in the system to serve as a power source. Regarding claim 14, Gong in view of Kempton teaches the method according to claim 13, wherein the stopping discharging to the load device (Gong - ¶0057 and Fig. 4) after the vehicle is switched to the power supply state (Kempton - ¶0052) comprises: after receiving first response information from the vehicle, stopping discharging to the load device (Gong - ¶0057 and Fig. 4), wherein the first response information indicates that the vehicle has been switched to the power supply state (Kempton - ¶0052: 304 and VL are in mutual communication regarding reverse flow of power into EVSE 104 from EVE 102). Regarding claim 15, Gong teaches the method according to claim 13, wherein before the conducting, after the second condition is met, the path through which the power supply device supplies power to the load device, the method further comprises: after the vehicle stops the power supply state, conducting, by the charging and discharging switching apparatus, the path through which the power supply device supplies power to the load device switch (Gong - ¶0057 and Fig. 4).

Shi teaches wherein the charging and discharging switching apparatus is provided with second setting information, and the second setting information comprises at least one of the following information: power consumption statistics information of the load device (¶0008: real time load conditions), charge state information of the vehicle, travel distance information of the vehicle, or charging information of the power supply device (alternative claim language used); and wherein the controller is further configured to: calculate a power supply time segment of the vehicle based on the second setting information (¶0047: V2G dispatching plan for a period of time for the willing vehicle); based on a current time point being within the power supply time segment of the vehicle, determine that the first condition is met (Fig. 1 and ¶0053-0055: examiner interprets when a vehicle is willing to participate in V2G within the planned period of time, the first condition is met); and based on the current time point being beyond the power supply time segment of the vehicle, determine that the second condition is met (Fig. 1 and ¶0053-0055: examiner interprets when it is not within the planned period of time, the second condition is met). Gong and Shi both disclose power distribution systems involving electric vehicles. It would have been obvious for a person having ordinary skill in the art before the effective filing date of the instant application to incorporate the designated time periods for V2G in the system of Shi into the system of Gong to efficiently manage the demand from the grid while preserving as much as possible the life of batteries in electric vehicles (¶0004).
