Applicant is reminded that the Examiner is entitled to give the broadest reasonable interpretation to the language of the claims. Furthermore, the Examiner is not limited to Applicants' definition which is not specifically set forth in the disclosure. Information Disclosure Statement The information disclosure statement filed August 9, 2023 has been received and considered. Specification The disclosure is objected to because of the following informalities: In paragraph 0023, "vehicle 21" should read "vehicle 12". In paragraph 0028, "step S18" should read "step S16". Appropriate correction is required. Claim Rejections - 35 USC § 102 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. 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 – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hiroyuki (JP H09170936). Regarding claim 1, Hiroyuki discloses a data logging assembly for a vehicle (Hiroyuki, [0007] regarding a data logger stored in the trunk of a vehicle) comprising: a substrate (Hiroyuki, Fig. 1 regarding the data logger consisting of a control circuit, clock IC, memory unit, battery, IC card I/F, RS-232C I/F, temperature measurement unit, analog input unit, ECU monitor input unit, SW input unit, regulator, and relay switch. As these all are part of the data logger, they must be fixed to a substrate.); a data logger mounted on the substrate, the data logger being configured to receive and store vehicle data (Hiroyuki, [0012] regarding the main CPU controlling each part of the data logger and storing, reading, and holding data in the 40 MB memory unit); and a power source mounted on the substrate, the power source being electrically connected to the data logger (Hiroyuki, [0009] regarding a battery provided in the data logger).

Sumcad teaches wherein the power source being configured to supply power to the data logger when the vehicle is in an ignition off state (Sumcad, [0022] regarding the data logger being powered by its own independent power source when the vehicle engine is off). Hiroyuki and Sumcad are considered to be analogous to the claimed invention because they are in the same field of data logging. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hiroyuki to incorporate using the data loggers independent power source when the vehicle engine is off, as disclosed by Sumcad, with a reasonable expectation of success because doing so would yield the predictable result of preventing the vehicle battery from being discharged even when the vehicle is not in use. Regarding claim 5, Hiroyuki in view of Sumcad teaches the data logging assembly as claimed in claim 4, wherein the vehicle battery is configured to supply power to the data logger when the vehicle is in an ignition on state or in an engine on state (Hiroyuki, [0024] regarding the data logger receiving power from the regulator which receives power from the sub-battery when the relay switch is turned on and the relay switch turning on when it is detected that the operator turns on the ignition key of the vehicle). Regarding claim 6, Hiroyuki discloses the data logging assembly as claimed in claim 1, but fails to explicitly disclose wherein the data logger is configured to be connected to a telematics unit of the vehicle to transmit the stored data. Sumcad teaches wherein the data logger is configured to be connected to a telematics unit of the vehicle to transmit the stored data (Sumcad, [0022] regarding the data logger being coupled to the telematics unit & [0024] regarding the telematics unit sending or uploading recorded data from the data logger). Hiroyuki and Sumcad are considered to be analogous to the claimed invention because they are in the same field of data logging. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hiroyuki to incorporate transmitting stored data using the telematics unit, as disclosed by Sumcad, with a reasonable expectation of success because doing so would yield the predictable result of sending the stored data. Regarding claim 7, Hiroyuki in view of Sumcad teaches the data logging assembly as claimed in claim 6. Sumcad further teaches wherein the data logger is configured to transmit the stored data at a predetermined interval (Sumcad, [0024] regarding timer activity being a trigger event for automatically triggered uploads & [0025] regarding timer activity including uploading recorded data from the vehicle after a specified amount of time (i.e., send recorded data from the data logger after a specified amount of time)). Hiroyuki and Sumcad are considered to be analogous to the claimed invention because they are in the same field of data logging. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hiroyuki, as modified, to incorporate transmitting stored data after a specified amount of time, as disclosed by Sumcad, with a reasonable expectation of success because doing so would yield the predictable preventing the memory of the data logger from being too full. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Hiroyuki in view of Sumcad, and further in view of Jauss (US 2023/0073058). Regarding claim 8, Hiroyuki in view of Sumcad teaches the data logging assembly as claimed in claim 7, but does not explicitly teach wherein the data logger is configured to overwrite the stored data after transmitting the stored data. Jauss teaches to overwrite the stored data after transmitting the stored data (Jauss, [0068] regarding stored and communicated events are allowed to be overwritten (i.e., data that has been transmitted can be overwritten)). Hiroyuki and Jauss are considered to be analogous to the claimed invention because they are in the same field of data storage. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have modified Hiroyuki, as modified, to incorporate overwriting data that has already been sent, as disclosed by Jauss, with a reasonable expectation of success because doing so would yield the predictable result of preventing the memory from being too full. Hiroyuki, as modified, teaches wherein the data logger is configured to overwrite the stored data after transmitting the stored data. Claims 9-13 are rejected under 35 U.S.C. 103 as being unpatentable over Hiroyuki in view of Bourilkov (US 2021/0296907).
