Claim Rejections - 35 USC § 102 07-06 AIA 15-10-15 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. 07-07-aia AIA 07-07 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – 07-15-aia AIA Claim(s) 1-3 is/are rejected under 35 U.S.C. 102 (a) (1) as being anticipated by Ishibashi et al . Regarding claim 1, Ishibashi et al. disclose an apparatus comprising: a power conversion device to which power is supplied from an external system (S1 in Fig. 9); and a controller (11 in Fig. 4) that controls an operation of the power conversion device, wherein first and second battery packs (LIBM and LFPM) different from each other in type are connected to the power conversion device in parallel (Abstract, a first battery module and a second battery module that are connected in parallel and have different characteristics…), the controller stores a first charge profile for the first battery pack and a second charge profile for the second battery pack, the controller charges the first battery pack by operating the power conversion device based on the first charge profile, and the controller charges the second battery pack by operating the power conversion device based on the second charge profile ([0124]-[0140]). Regarding claim 2, Ishibashi et al. disclose the apparatus according to claim 1, wherein the power conversion device has a first terminal and a second terminal, one of the first and second battery packs is connected to the first terminal, and the other of the first and second battery packs is connected to the second terminal, the controller obtains identification information for identifying a type of a corresponding battery pack connected to each of the first terminal and the second terminal, from the first and second charge profiles, the controller selects, based on the identification information, a charge profile to be used to charge the battery pack connected to the first terminal and a charge profile to be used to charge the battery pack connected to the second terminal, and the controller charges the battery pack connected to the first terminal and the battery pack connected to the second terminal by operating the power conversion device based on the selected charge profiles. Fig. 6 and 7 shows configuration of a first battery module and a second battery module and how those battery modules are connected to the controller in accordance with a charge profile ([0065] Notably, a number and connection arrangement of the battery cells can be changed suitably in accordance with purposes of the battery module. For example, the plurality of battery cells LFP may be connected in parallel. Further, sets of the plurality of battery cells LFP being connected in parallel (which may be referred to as a sub module) may be connected serially. [0101] The battery module LIBM includes battery cell unit 202 formed of one or more battery cells LIB. In this example, nine battery cells LIB (battery cell LIB1, battery cell LIB2, . . . , battery cell LIB9) configure the battery cell unit 202. In one embodiment, the nine battery cells LIB are connected serially. Notably, a number and connection arrangement of the battery cells can be changed suitably in accordance with purposes of the battery module. For example, the plurality of battery cells LIB may be connected in parallel. Further, sets of the plurality of battery cells LIB that is connected in parallel (which may be referred to as a sub module) may be connected serially.). Regarding claim 3, Ishibashi et al disclose the apparatus according to claim 1, wherein the first battery pack is a ternary lithium ion battery, and the second battery pack is an iron-phosphate-based lithium ion battery (LIBM and LFPM ([0037]-[0040]) . Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Kusch et al. disclose an apparatus and method for charging an electric vehicle.
