Office Action

§102
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 . This Office Action responses to the Application filed on 06/06/2025. Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. CN202411404948.3 and CN202422444826.9, filed on 10/08/2024. Information Disclosure Statement Information Disclosure Statement (IDS) filed on 09/17/2025 was considered. Claims 1-20 are pending for examination. Note to Applicant In the case of amending the claimed invention, Applicant is respectfully requested to indicate the portion(s) of the specification which dictate(s) the structure relied on for proper interpretation and also to verify and ascertain the metes and bounds of the claimed invention. Claim Objections Claims 1, 3, 11, and 13 are objected to because of the following informalities: Claim 1 lines 1-2 recites “an alternating current[[, AC,]] (AC) input interface, a first AC/direct current[[, DC,]] (DC) conversion module”. The recitation should be “an alternating current, AC, input interface, a first AC/direct current, DC, conversion module”. Similarly, acronyms in claim 11 should be enclosed by parentheses and followed by written in full text. Because claim 11 is an independent claim. Semicolon or new line with proper indentation should be used to further segregate subcombinations or related steps. Currently, each limitation and subcombinations or related steps merely separate by commas. An example for claim 1 as follows: A power supply circuit, comprising: an alternating current, AC, input interface[,]; a first AC/direct current, DC, conversion module[,]; a second AC/DC conversion module[,]; and an AC output interface[,]; the AC input interface being configured to be connected to an external AC power supply[,]; each of the first AC/DC conversion module and the second AC/DC conversion module being configured to be connected to a battery module[,]; the AC input interface and the AC output interface being electrically connected to each other to form a first branch circuit[,]; the AC input interface, the first AC/DC conversion module, the second AC/DC conversion module, and the AC output interface being sequentially electrically connected to form a second branch circuit, wherein: the first branch circuit is configured to output electric energy through the AC output interface by using the external AC power supply when the external AC power supply is available; and the second branch circuit is configured to output electric energy to the AC output interface through the second branch circuit by using the external AC power supply when the external AC power supply is available, and/or the second branch circuit is configured to output electric energy to the AC output interface through the second AC/DC conversion module by using the battery module when the external AC power supply is available or unavailable. Regarding claims 11, the claim is similarly objected for the same reason as in independent claim 1 above. Regarding claims 3 and 13, the claims recite: “the first AC/DC conversion module comprises a first AC/DC sub-conversion module and a first DC/DC conversion module connected to the first AC/DC sub-conversion module; and the second AC/DC conversion module comprises a second AC/DC sub-conversion module and a second DC/DC conversion module connected to the second AC/DC sub-conversion module”; should be: “the first AC/DC conversion module comprises a first AC/DC sub-conversion module and a first DC/DC conversion module; wherein, the first DC/DC conversion module is connected to the first AC/DC sub-conversion module; and the second AC/DC conversion module comprises a second AC/DC sub-conversion module and a second DC/DC conversion module; wherein, the second DC/DC conversion module is connected to the second AC/DC sub-conversion module”. Appropriate correction is required. Claim Rejections - 35 USC § 102 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 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.
