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 . Rejections Withdrawn 1. The 35 U.S.C. 102(a) rejection of claims 1-20 anticipated by Ju et al. has been withdrawn due to applicant’s amendment filed on 1/2/26. New Rejection Claim Rejections - 35 USC § 102 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 2. Claim(s) 13-22 is/are rejected under 35 U.S.C. 102(a) as being anticipated by Ju et al. (US11088410). As to claim 13, Ju et al. discloses a busbar including a first slot and a first bent portion (figure 15 number 22c) that establishes a base of the first slot (23a); a first battery cell including a first tab terminal (12) that extends through the first slot such that the first tab terminal is positioned against an upper surface of the first bent portion, wherein a portion of the first tab terminal is exposed within the first slot for welding; and a weld that secures the first tab terminal to the upper surface of the first bent portion (col. 5 lines 17-25). As to claim 14, Ju et al. discloses wherein the first tab terminal is received within the first slot such that at least a portion of the first tab terminal is positioned on an opposite side of the busbar from a housing of the first battery cell (figure 10 number 23,23a,20). As to claim 15, Ju et al. discloses wherein the first slot is flanked by a first crimped portion and a second crimped portion of the busbar (figure 3b number 23a). As to claim 16, Ju et al. discloses, wherein each of the first crimped portion and the second crimped portion includes an inner curved surface that is configured to limit an insertion distance of the first tab terminal into the first slot (figure 3b number 23a). As to claim 17, Ju et al. discloses comprising an elastic guide that is configured to urge the first tab terminal into the first slot (figure 10 number 30). As to claim 18, Ju et al. discloses wherein the elastic guide is part of a busbar frame that is secured to the busbar, and further wherein the busbar frame and the busbar establish a bus bar module of the traction battery pack (figure 10 number 30). As to claim 19, Ju et al. discloses wherein the busbar includes a second slot and a second bent portion, and further wherein a second tab terminal of a second battery cell extends through the second slot and is supported by the second bent portion (figure 4b). As to claim 20, Ju et al. discloses wherein the busbar electrically connects the first battery cell and the second battery cell (figure 4b). As to claim 21, Ju et al. discloses wherein the portion of the first tab terminal is spaced apart from an upper edge of the first slot (figure 15 number L3). As to claim 22, Ju et al. discloses wherein a distal tip of the first tab terminal is received in abutting contact with the inner curved surface to limit the insertion distance into the first slot (figure 4b). Allowable Subject Matter Claims 1,3-9,12,23 are allowed. The following is an examiner’s statement of reasons for allowance: The prior art fail to teach or suggest the busbar frame includes an elastic guide comprising a flexible clip-like feature having a curved body configured to resiliently urge the tab terminal into the slot and bias the tab terminal against the upper surface of the bent portion. Applicant teaches this to conveniently locate and position one or more battery cell tab terminals relative to a slot feature of the busbar. The busbars provide for a more consistent and accurate tab terminal alignment and welding, reduce welding errors, and allow for simple and convenient weld repairs. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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. /JANE J RHEE/Primary Examiner, Art Unit 1724
