Office Action

§102 §112
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 . 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. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 01/22/2025 has been considered by the examiner. Oath/Declaration Oath/Declaration as file 01/22/2025 is noted by the Examiner. 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 10-22 are 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. Claim 10 recites the limitation “…a detection device for an electrical energy store of a motor vehicle for detecting a fault of at least one energy storage cell of an interconnection of energy storage cells of the energy store…” in lines 1-3 of Claim 10. It is not clear if the underlined limitation in question refers to the same “electrical energy store of the motor vehicle” disclosed earlier in Claim 10 or if it refers to a different “energy store”. If this is the case, then please change the limitation in question to “the electrical energy store of the motor vehicle”. Claim 10 recites the limitation “…a current sensor configured to detect current values of the interconnection …” in line 4 of Claim 10. It is not clear if the underlined limitation in question refers to the same “interconnection of energy storage cells” disclosed earlier in Claim 10 or if it refers to a different “interconnection”. If this is the case, then please change the limitation in question to “the interconnection of energy storage cells”. Claim 12 recites the limitation “…wherein the current sensor comprises a current sensor for each interconnection …” in line 2 of Claim 12. It is not clear if the underlined limitation in question refers to the same “interconnection of energy storage cells” disclosed earlier in Claim 10 or if it refers to a different “interconnection”. If this is the case, then please change the limitation in question to “the interconnection of energy storage cells”. Claim 16 recites the limitation “…further teaches the electrical energy store according to claim 15…” in line 1 of Claim 15. It is not clear if the underlined limitation in question refers to the same “electrical energy store for the motor vehicle” disclosed earlier in Claim 15 or if it refers to a different “electrical energy store”. If this is the case, then please change the limitation in question to “the electrical energy store for the motor vehicle”. Claim 18 recites the limitation “…detecting current values of the interconnection …” in line 3 of Claim 18. It is not clear if the underlined limitation in question refers to the same “interconnection of energy storage cells of the electrical energy store” disclosed earlier in Claim 18 or if it refers to a different “interconnection”. If this is the case, then please change the limitation in question to “the interconnection of energy storage cells of the electrical energy store”. Claim 20 recites the limitation “…detecting the current values using a current sensor for each interconnection …” in line 2 of Claim 20. It is not clear if the underlined limitation in question refers to the same “interconnection of energy storage cells of the electrical energy store” disclosed earlier in Claim 18 or if it refers to a different “interconnection”. If this is the case, then please change the limitation in question to “the interconnection of energy storage cells of the electrical energy store”. Claims 11-17 are also rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph as they further limit rejected Claim 10. Claims 19-22 are also rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph as they further limit rejected Claim 18. Please make the proper corrections.

Allowable Subject Matter Claims 13 and 21 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is an examiner’s statement of reasons for allowance: Regarding claim 13, the prior art does not teach or suggest, in combination with the rest of the limitations of claim 10, “…wherein the storage and evaluation apparatus is configured to: determine gradients of the cell voltage curves and the current curve; and detect the fault of at least one energy storage cell in response to a gradient of the associated cell voltage curve being directed oppositely to a gradient of the current curve at least in sections.” Regarding claim 21, the prior art does not teach or suggest, in combination with the rest of the limitations of claim 18, “…determining gradients of the cell voltage curves and the current curve; and detecting the fault of at least one energy storage cell in response to a gradient of the associated cell voltage curve being directed oppositely to a gradient of the current curve at least in sections.” Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Butzmann US 2013/0300426 - A battery system with at least one module includes a plurality of battery cells. A cell voltage detecting circuit is associated with each battery cell of the plurality of battery cells. The cell voltage detecting circuits of the at least one module are connected to a multiplexer. An output of the multiplexer is connected to a communication bus via an analog-digital converter. The communication bus is connected to an evaluating unit. Thomson et al. US 2020/0014219 - A battery system includes a battery module, an active cell balancing circuit, and a battery controller. Each cell has diametrically-opposed positive and negative cell tabs. The circuit includes voltage sensors and, at each end of the battery module, first and second tiers of switches and an energy storage element. Each voltage sensor is located between a different pair of adjacent cells. The controller receives measured voltages from the sensors indicative of an electric potential between adjacent battery cells. Responsive to the measured voltages, the controller commands the first tier to selectively connect or disconnect designated pairs of cells to the corresponding second tier. Maier US 2022/0144129 - A method for determining a cell voltage of a battery cell of a traction battery of a vehicle includes filtering the cell voltage of the battery cell by a filtering device, sampling the filtered cell voltage by an analogue to digital converter, transferring the filtered and sampled cell voltage as a cell voltage signal to a computing device, evaluating the cell voltage signal by the computing device, determining a ripple value which describes a ripple of the cell voltage, and evaluating the cell voltage signal depending on the ripple value.
