Office Action

§112
CTFR 18/363,876 CTFR 96262 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Priority 02-26 AIA Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Response to Amendment/Argument Amendment and Argument filed on 01/29/2026 are considered. Independent claims 1, 8 and 16 are amended. Claims 2, 9, 10, 17 are cancelled. Claim 21-24 are newly added. Claim rejection under 35 U.S.C 101: Applicant included a patent eligible subject matter in the independent claims 1, 8 and 16. The independent claims now integrate the abstract idea into the practical application. Therefore, the rejection under 101 is withdrawn. Claim rejection under 35 U.S.C 103: The further search and consideration did not find applicant argued limitation “based on a determination, by the processor of the battery monitoring system, that the first battery cell and the second battery cell are being charged or discharged at a temperature below approximately twenty degrees Celsius and that an absolute value of a difference between the first SOC and the second SOC is greater than a threshold value: obtaining a first capacity retention rate for the first battery cell and a second capacity retention rate for the second battery cell, wherein each capacity retention rate is defined as a ratio of a capacity of the corresponding battery cell at the current temperature to a nominal capacity at approximately twenty degrees Celsius and is obtained via a table look-up based on the chemistry and the temperature” Examiner noticed some unclear and new matter in the amended and new claims which are addressed below. Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claim 1, 3-8, 11-16, 18-24 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding independent claims 1, 8, 15 and 21 recite a term “approximately” twenty degree Celsius. Since, the specification does not provide a clear guidance for the range of temperature for “approximately twenty degree Celsius”, Examiner views the term approximately twenty degree Celsius is unclear. Applicant is suggested to remove or delete the word “approximately” for the purpose of clarity of the intended temperature. Claim 22 and 23 recites “when the vehicle is at rest for a sufficient amount of time”. It is unclear which condition to be considered a sufficient amount of time. Applicant is suggested to recite an exact time or remove the unclear terms for the purpose of clarity of the intended amount of time. Dependent claims 3-7, 11-14, 16, 18-24 are also rejected under 112 due to dependency on the independent claims. 07-30-01 AIA The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. 07-31-01 Claim 24 rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding the limitation of claim 24, examiner is unable to find the support in the specification. Therefore, claim 24 is considered a new matter. The applicant is suggested to provide support of the new or amended claims referring to the paragraphs in the specification. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. KAWAMURA et al US 20170285109 A1 discusses discuss estimating correlation between SOC and OCV of battery. Zhang et al US 20200278399 A1 discusses estimating updating SOC of a battery. 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.
