Office Action

§102 §103 §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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/01/2025 has been entered. Response to Amendment Claims 1-2, 12-13, and 21-22 are amended. Claims 1-24 are pending. 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 5, 7, 16 and 22-23 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. Claims 5, 16 and 23 recite “setting a point” and “the setting point” with the amended claims it is now unclear if the setting point refers to the previous setting a point or the newly amended setting point in their respective independent claims. For the purposes of examining, they are considered to refer to the setting a point. Claims 7 and 22 recites the limitation "the point", claim 22 recites it twice. There is insufficient antecedent basis for this limitation in the claim.

In claim 22, Nakayama discloses wherein, in the first method, the first circuit is configured to: when the point is reached, calculating a resistance value of the battery (Column 12 Eq. 4, Lines 55-65 Column 19 Lines Eq. 6, 1-20, Column 23 Eq. 7, Lines 43-62) for a first interval before the point (See Fig. 10 examiner considers the period before Icv to be said interval); updating the full SOC value based on correlation information correlating SOC and open- circuit voltage (OCV), the calculated resistance value, a cutoff current value, and the cutoff voltage value (Column 12 Eq. 4, Lines 55-65 Column 19 Lines Eq. 6, 1-20, Column 23 Eq. 7, Lines 43-62); setting a subsequent point for updating the full SOC value (Fig. 12, Column 7 Lines 7-30); and when the battery reaches the set subsequent point, iteratively updating the full SOC value based on a resistance value of the battery for an interval between the point and the subsequent point, the correlation information, the cutoff current value, and the cutoff voltage value (Column 12 Eq. 4, Lines 55-65 Column 19 Lines Eq. 6, 1-20, Column 23 Eq. 7, Lines 43-62). Nakayama does not explicitly disclose calculating a first average resistance value of the battery for a first interval before the point; (Emphasis added). CHA teaches calculating a first average resistance value of the battery for a first interval before the point (Par. 17-18 “average internal resistance value” “the predefined time”), updating the full SOC value based on an average resistance value (Par. 17-18) Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was filled to calculating a first average resistance value of the battery for a first interval before the point based on the teachings of CHA in combination with the disclosure of Nakayama in order to correct for measurement error of a current sensor over time (CHA par. 22) thus leading to a more accurate system. Response to Arguments Applicant's arguments filed 12/01/2025 have been fully considered but they are not persuasive. in regards to applicant’s 102 arguments, the examiner respectfully disagrees. The claims do not specify any limitations on the CC charging mode that would exclude the inclusion of the change point cited by the examiner as the CV charging has not yet started, examiner considers this to still be in a CC charging mode. Thus, as described above, Nakayama discloses the cited features. Regarding applicants 103 arguments the examiner respectfully disagrees, the prior art f record is within the BRI as described above. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US 20160274193 A1, IMAIZUMI teaches wherein the iteratively updating of the full SOC value (Fig. 4 S11) while in the CC charging mode (Fig. 4, S2) comprises determining whether the charging of the battery in the CC charging mode has reached a set point for updating the full SOC value (Fig. 4, S8, “n” is considered to be said setpoint); and when the charging of the battery in the CC charging mode has reached the set point, updating the full SOC value while in the CC charging mode (Fig. 4, S9), and iteratively updating the full SOC value while in the CV charging mode (see fig. 3); Any inquiry concerning this communication or earlier communications from the examiner should be directed to BRANDON J BECKER whose telephone number is (571)431-0689.
