Office Action

§112
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 . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being incomplete for omitting essential structural cooperative relationships of elements, such omission amounting to a gap between the necessary structural connections. See MPEP § 2172.01. The omitted structural cooperative relationships are: Regarding to claims 1, 7, 13: The claims cite the element “the input unit”/”an evaluation condition input process” without a clear linking to the other elements/processes of the claim body. In addition, the claim preamble is for the evaluation of an accelerated idle life of a secondary battery, which is performed by the reference performance test of the input unit/the evaluation condition input process. The claims however are unclear about the functions/roles of the data computation unit and the acceleration factor calculation unit, and the purpose of computing the evaluation period and the acceleration factor in the evaluation of the accelerated idle life of the secondary battery. Claims 2-6, 8-12, 14-20 are rejected because they depend on claim 1, 7, or 13. Response to Arguments Applicant's arguments filed 4/15/2026 have been fully considered but they are not persuasive. In response to Applicant’s assertion that the claim language defined a closed, end-to-end evaluation workflow (inputs ͢ computed period/rates ͢ computed acceleration factor), the claimed workflow however appears as not as closed and end-to-end because: The claim language does not define wherein the inputted idle temperature and measurement period are used or associated in the computation process to define a sequence of inputting and computing (end-to-end) process, and the claim language also does not define wherein the calculated acceleration factor of the secondary battery is used or considered for evaluating the accelerated idle life of the secondary battery to define a closed process. 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.
