Office Action

§103
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 . Response to Amendment Applicant' s amendment and response filed 10/9/2025 has been entered and made record. This application contains 17 pending claims. Claims 1, 3, and 5-17 have been amended. Claims 2 and 4 have been cancelled. Claims 19 has been added. Response to Arguments Applicant’s arguments filed 10/9/2025 regarding claims rejections under 35 U.S.C. 101 in claim 1-18 have been fully considered and are persuasive. Claims 1, 9, and 17 have been amended, and the amended claims limitations integrated the abstract idea into a practical application, and overcome the 101 rejections. Thus, the 101 rejections in Claim 1-18 have been withdrawn. Applicant’s arguments filed 10/9/2025 regarding claims rejections under 35 U.S.C. 112(f) claim interpretation in claim 1-16 have been fully considered and are persuasive. Claims 1, 3, and 5-17 have been amended, and thus, the claims are no longer interpreted under the 112(f). Applicant’s arguments filed 10/9/2025 regarding claims rejection under 35 U.S.C. 103 with respect to claims 1-18 have been fully considered but they are not persuasive. The claims 1, 9, and 17 have been amended, and some features of the amended claims limitation necessitate a new ground of rejection. Thus, a newly discovered prior art, “Kim KR20100085791A”, will be used in combination with prior arts cited in the previous office action to reject the amended claims limitations. The applicant argues on pages 10-14 of the remark filed on 10/9/2025 that “Applicant respectfully submits that this combination of elements as set forth in independent claim 1 is not disclosed by the prior art of record. … In contrast to the claimed invention, Applicant respectfully submits that the references, taken alone or in combination, fail to teach or suggest "the diagnoser being configured to determine that the battery pack is reusable, when a deviation of at least one of the degree of aging of the battery cell and the degree of aging of the battery module falls within a reference range, wherein when the deviation falls within the reference range, the SOH of the battery pack is greater than or equal to a reference value" in combination with the other elements of claim 1. …”. Applicant continue to argue that “However, Osaka is silent regarding, determining that a battery pack is reusable, when a deviation of at least one of the degree of aging of the battery cell and the degree of aging of the battery module falls within a reference range (see page 18 of the Office Action). Furthermore, Osaka is also silent regarding, when the deviation does fall within the reference range, a SOH of the battery pack is greater than or equal to a reference value to determine that the battery pack is reusable, as Osaka is silent regarding a reference SOH value. Therefore, Osaka teaches a different configuration than the current application and fails to teach or suggest the claimed features.” The applicant further argues that “Furthermore, Jung also teaches a different configuration than the current application. … However, Jung is silent regarding when the deviation does fall within the reference range, a SOH of the battery pack is greater than or equal to a reference value to determine that the battery pack is reusable. Specifically, Jung does not teach a reference value other than the control disable entry setting value. However, the control disable entry setting value is not at all related to a state of health of the battery. Therefore, Jung also teaches a different configuration than the current application. Accordingly, the references, taken alone or in combination, fails to teach or suggest the claimed features.” The Examiner respectfully disagrees applicant's argument. Osaka teaches that the storage unit 46 stores the second Cole-Cole plot of the battery 30 having a state of health (SOH) of 100% which has not deteriorated in first measurement. That is, the state of health (SOH) indicates that the smaller its value is, the more greatly deterioration progresses (Osaka, [0087], [0113]). The battery that has a SOH of 100% in the first measurement is greater than the reference value, and is reusable. Osaka also teaches that RC in a battery cell having an SOH of 90% is 5.11 mΩ, and RC in a battery cell having an SOH of 80 % is 6.25 mΩ (Osaka, [0142]). The battery that has a SOH of 90% is within the reference value, and is reusable. Thus, Osaka teaches determining that a battery pack is reusable, when a degree of aging of the battery cell and the degree of aging of the battery module falls within a reference range. Jung teaches that the BMS 220 measures and calculates the deterioration of the battery cells and modules (Jung, [0039]), and the BMS 220 has the intensive deterioration state condition of the battery cell and/or module when the difference in deterioration from other battery modules/cells is greater than a predetermined level, etc. (Jung, [0040], [0050]). Hence, Jung teaches measures and calculates the deterioration or SOH of the battery cells and modules by comparing deterioration levels between the batteries, and their deterioration levels difference with a predetermined or reference level. Jung further teaches that when the measuring voltage of the battery cell 10 is greater or less than a predetermined reference voltage, the controller 130 operates the cell switching unit 120 of the corresponding battery cell 10 to block a connection with another battery cell 10. In other words, under the assumption that the battery has appropriate specifications required by the system, the corresponding battery cell is blocked when control problems occur. Further, only the battery having a problem is blocked and thus the corresponding battery is not used (Jun, [0005]). Hence, the battery with a SOH within a predetermined reference voltage is reusable. Therefore, the combination of Osaka and Jung teaches determine that the battery pack is reusable, when a deviation of at least one of the degree of aging of the battery cell and the degree of aging of the battery module falls within a reference range, wherein when the deviation falls within the reference range, the SOH of the battery pack is greater than or equal to a reference value. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1, 3, and 5-19 are rejected under 35 U.S.C. 103 as being unpatentable over Osaka et al.

Osaka does not explicitly teach when a deviation of at least one of the degree of aging of the battery cell and the degree of aging of the battery module falls within a reference range. Jung teaches determine that the battery pack is reusable, when a deviation of at least one of the degree of aging of the battery cell and the degree of aging of the battery module falls within a reference range ([0005] discloses when the measuring voltage of the battery cell 10 is greater or less than a predetermined reference voltage, the controller 130 operates the cell switching unit 120 of the corresponding battery cell 10 to block a connection with another battery cell 10, and only the battery having a problem is blocked and thus the corresponding battery is not used (i.e., the measuring voltage of the battery cell within a predetermined reference voltage is reusable - emphasis added by Examiner)); [0010] “discloses determining that the highest deterioration is greater than an intensive deterioration entry setting value and a second selective control to perform the exclusion from the control object when the highest deterioration is less than the setting value, by comparing the highest deterioration with the intensive deterioration entry setting value (i.e., the deterioration level of battery pack that falls within the reference range would be reusable - emphasis added by Examiner).”; [0050] discloses “The BMS 220 has the intensive deterioration state condition of the battery cell and/or module (e.g., when the difference in deterioration from other battery modules/cells is greater than a predetermined level, etc. (i.e., the battery pack with deterioration state condition of SOH would be reusable when the difference in deterioration states of the batteries is less than the setting value or the deviation of the degree of aging of the battery cell and/or module is within a reference range - emphasis added by Examiner)).”; and wherein when the deviation falls within the reference range, the SOH of the battery pack is greater than or equal to a reference value ([0003], [0010] and [0037] disclose generate deterioration of the battery cells 410a to 410n and/or the battery modules 310a to 310n, a state of health (SOH), and difference in deterioration, a state of charge (SOC). Control the performance of the battery pack by minimally maintaining a voltage deviation in the battery cells within the battery pack; and determining that the highest deterioration is greater than an intensive deterioration entry setting value (i.e., the deviation falls within the reference range - emphasis added by Examiner)). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Jung into Osaka for the purpose of sensing the battery pack and performing a selective control to select a control object of a unit element of the battery pack or an intensive control to intensively use the control object of the unit element using the battery state so that the deterioration of the battery state can be evaluated. This combination would improve in preventing deterioration of a specific battery module/cell from suddenly increasing, and extending lifespan of the overall battery pack. The combination of Osaka and Jung does not explicitly teach wherein, based on the diagnosed state of the battery pack by the diagnoser, a battery management system is configured to control an on and off of a switch that controls charging and/or discharging of the battery pack. Kim teaches wherein, based on the diagnosed state of the battery pack by the diagnoser, a battery management system is configured to control an on and off of a switch that controls charging and/or discharging of the battery pack (Page 6, Lines 15-20 discloses “The above monitoring and control means, when an abnormality is detected or expected in the abnormal state or aging state of the battery pack (Stack) or in the charging/discharging state, generates a gate cut-off signal (Cut off) through a gate cut-off means of an embedded device configured in the monitoring and control means, thereby immediately blocking the switching element of the boost converter and the gate of the cut-off switch, thereby immediately stopping charging and discharging, thereby protecting the battery from an abnormal state.”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Kim into Osaka in view of Jung for the purpose of monitoring an aging condition or abnormal condition of the storage battery pack by a control system of a battery pack (stack) in order to detect an abnormality. This combination would improve in preventing accidents such as damage or explosion of the battery pack (stack) in advance by immediately blocking the switching element gate drive signal of the boost converter circuit.
