Office Action

§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 . Response to Amendment The amendment filed on May 21, 2026 is acknowledged. Claims 6-7 are currently amended. Claims 6-10 remain pending in the application. Claims 1-5 are canceled. Applicant’s amendments to the specification and claim 6 have overcome each and every objection and 112(b) rejection previously set forth in the Non-Final Office Action mailed on February 21, 2026. Applicant has filed both a marked up version and a clean version of the claims. In this Final Office Action, the marked up version of the claims is being examined. Applicant is respectfully requested to not include multiple claim listings within a response, and to ensure claim amendments comply with 37 CFR 1.121(c). The previous rejection under 35 U.S.C. 102 is withdrawn due to Applicant’s amendment. The previous double patenting rejection is withdrawn due to Applicant’s amendment. The previous rejection under 35 U.S.C. 103 is maintained. The terminal disclaimer filed on May 21, 2026 disclaiming the terminal portion of any patent granted on this application which would extend beyond the expiration date of Application No. 18/308955 (US 2024/0128560 A1) was disapproved in the review decision filed on May 22, 2026. Claim Objections Claim 7 is objected to because of the following informalities: in line 1 of claim 7, “according to claim 4 6” should read “according to claim 6”. Appropriate correction is required. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.

Annotated Fig. 14 above, ring wall covering portion covers an outer side wall of transition portion 231), the terminal covering portion, the ring wall covering portion and the limiting portions are combined to form an integral insulator. Chen et al. does not disclose wherein a plurality of limiting grooves are formed on the ring wall; the insulator further comprising limiting portions fitted in the limiting grooves; an outer peripheral wall of the ring wall covering portion is arranged in contact with the inner peripheral wall of the positioning groove, the limiting portions are formed on an outer wall of the terminal covering portion or an inner wall of the ring wall covering portion, or the limiting portions penetrate through the limiting grooves and are then connected to the terminal covering portion and the ring wall covering portion respectively, and the terminal covering portion, the ring wall covering portion, and the limiting portions are combined to form an integral insulator. Zeng et al. discloses that an outer peripheral wall of the ring wall covering portion is arranged in contact with the inner peripheral wall of the positioning groove (see Zeng et al. Annotated Fig. 7 below, positioning groove and ring wall covering portion). Zeng et al. is considered to be analogous to the claimed invention because it is in the same field of battery top cover structures. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have combined the battery top cover assembly as taught by modified Chen to with the teachings of Zeng et al. using known methods so that an outer peripheral wall of the ring wall covering portion is arranged in contact with the inner peripheral wall of the positioning groove, and the combination would have yielded the predictable result of securing the insulator and top cover structure together.

Annotated Fig. 14 above, depression), and the depressions are the second restricting portion (see Chen et al. Annotated Fig. 14 above); and the flanges are embedded in the depressions (see Chen et al. Annotated Fig. 14 above). Response to Arguments Applicant's arguments filed on May 21, 2026 have been fully considered but they are not persuasive. In response to Applicant’s argument on page 8 that Chen does not disclose the distinguishing technical features (1), “an inner peripheral wall of the positioning groove is arranged in contact with an outer peripheral wall of the conductive terminal structure,” but rather discloses that “the conductive terminal structure is positioned in the first sink portion 12 by means of radially outwardly protruding bumps”, it is the examiner’s position that Chen discloses the distinguishing technical features (1). The conductive terminal structure 20 includes the first connection portion 232 (see Chen Annotated Fig. 13 above), the outer peripheral wall of which is arranged in contact with the inner peripheral wall of the first sink portion 12, which is consistent with the broadest reasonable interpretation of distinguishing technical features (1). Applicant’s argument is not persuasive because Chen discloses the distinguishing technical features (1), and the rejection of amended claim 6 over Chen in view of Knoedler, Deng, and Yang is maintained. In response to Applicant’s argument on pages 8-9 that none of the references disclose the distinguishing technical features (2), “a ring wall formed on a top surface of the ring bottom, and a riveting body is formed at the top of the ring wall” in an integrally combined one-piece terminal fixture, the prior Office Action relied upon Chen to disclose these limitations. Chen discloses a second fixing component ([0093] and see Chen Annotated Fig. 13 above) that comprises a ring wall (see Chen Annotated Fig. 13 above, transition portion 231) formed on a top surface of the ring bottom (see Chen Annotated Fig. 13 above, first connection portion 232), and a riveting body (see Chen Annotated Fig. 13 above, second connecting portion 233) is formed at the top of the ring wall. Applicant’s argument is not persuasive because Chen discloses the distinguishing technical features (2), and the rejection of amended claim 6 over Chen in view of Knoedler, Deng, and Yang is maintained. In response to Applicant’s argument on page 9 that none of the references disclose the distinguishing technical features (3), a plurality of protrusions are formed on an inner wall of the terminal fixing cavity, a plurality of recesses are formed on an outer wall of the insulator, and the protrusions are correspondingly embedded in the recesses, the prior Office Action relied upon Chen to disclose these limitations (see Chen Annotated Fig. 13 above, protrusions and recesses). Applicant argues that based on distinguishing technical features (3), the terminal fixing cavity and the insulator are arranged in concave-convex fit, however, these limitations are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Applicant’s arguments are not persuasive because of the reasons set forth above, and the rejection of amended claim 6 over Chen in view of Knoedler, Deng, and Yang is maintained. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
