Office Action

§102 §103
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 . Election/Restrictions Applicant’s election without traverse of claims 3-6 in the reply filed on 11/20/2025 is acknowledged. Claims 1-2 and 7-9 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 11/20/2025. 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. Claim(s) 3 and 5 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zhou et al. (US Pub. NO.: 2022/0323981 A1) (hereinafter Zhou). Regarding claim 3, Zhou anticipates a glue spreading device for bonding a motor core, comprising a plurality of the cone (29) (corresponding to spreading blocks); a fixing plate (1) (corresponding to fixed base), wherein the fixing plate (1) is mounted on lower die seat (17) (corresponding to lower template), and an adhesive passage (104) (corresponding to glue groove) formed on top of fixing plate (1) for storing glue is formed on a top of fixing plate (1); and press plate (3) (corresponding to cover plate), wherein the press plate is mounted on fixing plate (1) and located above the adhesive passage (104), and a plurality of conical holes (262) are formed on press plate; and plurality of cone (29) are respectively arranged inside the conical hole (262), the top of the cone is not lower then a top of the press plate (3), and a bottom of the cone (29) is located inside of adhesive passage (104) for absorbing glue; wherein the cone (29) is configured to spread the glue on iron core sheet (corresponding to silicone steel sheet) when the glue spreading block is in contact with the iron core sheet. Regarding claim 5, Zhou anticipates nozzle (2) (corresponding to rebound rod) is movably inserted into positioning hole (103) (corresponding to rebound hole) on the fixing plate (1) and butted against the bottom of the cone (29); and spring (28), wherein the spring (28) is movably inserted on the nozzle (2), and two ends of the spring (28) are respectively abutted against positioning hole (103) and the nozzle (2) for jacking the cone (29). 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 and 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhou as applied to claims 3 and 5 above, and further in view of CN 116060246 A (hereinafter ‘246). Regarding claims 4 and 6, the limitations of claim 1 are taught by Zhou as cited above. Zhou is silent about limitations of claim 1. Zhou also discloses a glue spreading device for bonding a motor core. The device discloses a glue storage sponge, wherein the glue storage sponge (2) is mounted inside the glue groove (12) and the glue spreading blocks (3) are all mounted on the glue storage sponge (Fig. 1-6). The benefit of doing so would have been to store or absorb glue during bonding operation. It would have been obvious to a person of ordinary skill in the art to utilize glue storage sponge as taught by ‘246 within the glue spreading device as taught by Zhou. The benefit of doing so would have been to store or absorb glue during bonding operation. Regarding claim 6, ‘246 discloses a wear-resistant sleeve (7), where the wear-resistant sleeve (7) is movably inserted into the glue spreading hole (41) on the cover plate (4), a wear-resistant hole (71) is formed on the wear-resistance sleeve (7), the glue spreading block (3) is movably inserted into the wear-resistant hole (71), and the top of the glue spreading block (3) is flush with a top of the wear-resistant sleeve (7), or the top of the glue spreading block (3) is lower than the top of the wear-resistant sleeve (7) (Fig. 2-10). The benefit of doing so would have been to improve longevity of glue spreading block during bonding process. Given the wealth of knowledge, it would have been obvious to a person of ordinary skill in the art to utilize wear-resistant sleeve as taught by ‘246 within the glue device as taught by Zhou. The benefit of doing so would have been to improve longevity of glue spreading block during bonding process.
