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 .
Response to Amendment
The Amendment filed 12/1/2025 has been entered. Claims 1-20 remain pending in the application. Applicant’s amendments to the Specification and Claims have overcome every claim objection previously set forth in the Non-Final Office Action mailed 9/8/2025. The new grounds of rejection presented below are necessitated by the amendments. Accordingly, this Office Action is made Final.
Response to Arguments
Applicant's arguments filed 12/1/2025 have been fully considered but they are not persuasive.
Applicant submits in the third paragraph on page 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, the AC power grid 400, or the vehicle in the slave emergency power module 201 (Gong ¶’s [14, 16].
