Through the cooperation of the first charging terminal 2 and the second charging terminal 4, the charging box can be connected to the earphone. charging to ensure the battery life of the headset” in Page 10, Paragraph 7). 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 4, 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen (CN 115395607 A) hereinafter Chen in view of Wang et al (CN 216852306 U) hereinafter Wang Regarding claim 4, Chen teaches the device of claim 3, Chen does not specifically disclose the device further comprising wherein the hook structure includes an elastic part and a rigid part connecting the elastic part and the core module, and a region of the first profiling groove region for accommodating the core module and a region of the second profiling groove region for accommodating the rigid part are inclined towards each other however, Since it is known in the art as evidenced by Wang for a device to further comprise wherein the hook structure includes an elastic part and a rigid part connecting the elastic part and the core module, and a region of the first profiling groove region for accommodating the core module and a region of the second profiling groove region for accommodating the rigid part are inclined towards each other (“As shown in fig. 16, the earphone 100 includes a main body 110, a battery part 120, and an elastic connection part 130, and the elastic connection part 130 is used to connect the main body 110 and the battery part 120.
