Claim Rejections - 35 USC 102
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 6-9, are rejected under 35 U.S.C. 102(a)(1) as being anticipated by the prior art of record “LI” <US 20250385325 A1>.(As to claim 6, LI discloses):6. (Currently Amended) A method for active power flow control and equalization for electrochemical accumulators connected to an electrical grid, the method comprises [0180: “voltage may be controlled by the grid-connected inverter… on the DC bus or a certain intelligent battery unit…determined power according to the power distribution algorithm, maintaining the power balance”]:
acting on a power demand of a charge [0002: “requirement for the capacity and functions of energy storage systems”];
measuring battery voltage, current, and temperature [0015: “measuring voltage, current, pressure and/or temperature of the battery cel]”;

estimating a state of charge, health, and life of each battery in a bank [Fig. 6];
calculating energy to be dispatched by each battery in the bank [0068: “power of each power electronic intelligent battery unit is determined based on the battery status information provided by a plurality of the power electronic intelligent battery units, and the control strategy for each unit is determined in combination with the power interface control method of the power electronic intelligent battery unit.”];
dispatching energy proportional to the state of health, charge, and life in each battery of the bank [0180: “battery modules output determined power according to the power distribution algorithm, maintaining the power balance of the DC bus, and realizing efficient and intelligent parallel expansion” along with Fig. 6 that depicts the determination factors (health, state of charge and etc.) of power dispatch] [Additional similar disclosures are in Para. 42-53];
processing all data in a central controller [0068: “the control strategy for each unit is determined in combination with the power interface control method of the power electronic intelligent battery unit”]; and
dispatching all information in a communication bus [Fig. 6, 220].
(As to claim 7, LI discloses):7. (Currently Amended) The method according to claim 6, wherein the central controller calculates the state of charge, health, and life of each battery [Fig. 6 along with Para. 0098].
(As to claim 8, LI discloses):8. (Currently Amended) The method according to claim 6, wherein the central controller selects which batteries from the bank deliver more energy and which deliver a smaller amount of energy throughout their useful life [0024: “each battery cell, and realizing the balance of the state of charge of the battery cells by switching the switch transistor, through a certain balance algorithm, under the control of the processor.”] [Para. 0175 contains additional description about individual cell activity control algorithm].
(As to claim 9, LI discloses):9. (Currently Amended) The method according to claim 6, wherein the method is continuous and happens uninterruptedly until all energy in the battery bank is completely drained [0158: “ during the operation of the battery, the battery state of charge estimation process is continuously carried out, and the battery state of charge is continuously predicted, corrected and tracked, and the obtained battery state of charge information is further applied to the charge and discharge control and balance management of the battery.”].
