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 . Election/Restrictions Applicant’s election without traverse of claims 1 – 14 and 19 in the reply filed on 01/19/2026 is acknowledged. Claims 15-18, and 20 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 01/19/2026. The requirement is still deemed proper and is therefore made FINAL. 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 – 14 are rejected under 35 U.S.C. 103 as being unpatentable over Han (US 20210276723) in view of Kumar (US 20240116397). Regarding claim 1, Han teaches a charge status control system for controlling a state of charge of a battery (shown in figure 5 item 900 defined in paragraph [0046] as a flight control system controlling a battery item 400), comprising: a power generator configured to generate electrical power and to supply the electrical power to a load (figure 5 item 300 defined in paragraph [0037] as an electrical generator which supplies power to a load such as rotors to directly drive the rotors); a battery configured to store the electrical power generated by the power generator and to supply the stored electrical power to the load (shown in figure 5 item 400 battery defined in paragraph [0039] electrically connected to generator and to the load or rotors). Han does not explicitly teach a detection unit configured to detect a state of charge of the battery; and a control unit configured to, if a detection result of a remaining charge amount of the battery by the detection unit is a storage threshold or more, control the state of charge of the battery by discharging the electrical power stored in the battery to an external power source. Kumar teaches a detection unit configured to detect a state of charge of the battery; and a control unit configured to, if a detection result of a remaining charge amount of the battery by the detection unit is a storage threshold or more, control the state of charge of the battery by discharging the electrical power stored in the battery to an external power source (Figure 1 items 116, 120 and 122 are external devices which receive charge from onboard batteries. paragraph [0028] teaches wherein the State of Charge (SOC) of the batteries are determined. Paragraph [0031] teaches wherein the battery discharged to bring the state of charge to a certain level. Paragraph [0073] teaches wherein the external conditioning device may be connected to internal power packs items in figure 8 item 300. Paragraph [0076] teaches wherein the system controller may operate switches, connected to the conditioning device, based on the state of charge of the battery packs. Figure 6 and Paragraphs [0065] – [0067] wherein batteries are discharged externally, interpreted as the excess charge in power packs may be directed externally to an off-board conditioning device, by operating the switching devices to conduct the excess charge in the companion packs to the resistive elements where the excess charge is dissipated or consumed). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the charging system of the Han reference with the charging system of the Kumar reference so that batteries may be easily identified for removal. The suggestion/motivation for combination can be found in the Kumar reference in paragraph [0003] wherein batteries may be easily identified for removal.
