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 .
Response to Arguments
Applicant’s arguments, see page 7, filed 10/15/2025, with respect to the rejection(s) of claim(s) 1 under 35 USC 102have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Lee et al. (US 2011/0059347), herein after Lee.
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a).
Claim Rejections - 35 USC § 103
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 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.
Claim(s) 1, 4, 5, 9, 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ejiri et al. (US 2015/0270589), herein after Ejiri and Lee (US 2011/0059347).
Regarding claim 1, Ejiri discloses a secondary battery charging and discharging system comprising:
a tray (The battery block 1 further includes a pair of end plates 5 to hold the battery, paragraph [0026]) configured to accommodate a plurality of battery cells (A battery block according to the present invention that solves the problems includes a plurality of arranged battery cells; paragraph [0007]); an insulation pad (spacer pad 38, paragraph [0035])disposed in the tray, the insulation pad being disposable between the tray and an outermost battery cell among the plurality of battery cells so as to be contactable with one surface of the outermost battery cell (second spacers respectively disposed between the battery cells and each end plate and having a thermal insulating property for suppressing heat transmission between the battery cells and each end plate, paragraph [0007]),
a charging and discharging part configured to be electrically connected to first and second electrode leads of the plurality of battery cells accommodated in the tray (The plurality of battery cells 2 is disposed with positive electrode external terminals 2a and negative electrode external terminals 2b being alternately continuous along the arranged direction, paragraph [0027]); and

However, Ejiri is silent about heat sink pads disposed in the tray, the heat sink pads being arranged to separate adjacent battery cells of the plurality of battery cells.
Lee discloses heat sink pads (thermally interface material 550 in heat dissipation member 500, fig. 10) disposed in the tray , the heat sink pads being arranged to separate adjacent battery cells of the plurality of battery cells (the heat dissipation member 500 (include thermally interface material 550) disposed between the Cartridges 200 (paragraph [0103]) where the Cartridges include one or more battery cells, paragraph [0008]Note: a thermal interface material (TIM) is also known as a heat sink pad).
It would have been obvious to one of the ordinary skills in the art, before the effective filing date of the claimed invention to modify Ejiri’s system to have the sink pads between the battery cells as taught by Lee, in order to improve thermal management by efficiently moving heat away, preventing dangerous hotspots, ensuring uniform cell temperatures for stable performance, extending battery life, and reducing stress that causes failures, all by filling air gaps for better conduction to a cooling system.
Regarding claim 4, Ejiri further discloses wherein the insulation pad is configured to be in contact with 80% or more of an area of the one surface of the outermost battery cell (the insulator 3B cover more than 80% of the battery cell 2, fig. 7).
Regarding claim 5, Ejiri in view of Lee discloses the system of claim 1. However Ejiri is silent over the system wherein the heat sink pads are disposed such that three to ten battery cells of the plurality of battery cells are interposable therebetween.
Lee discloses wherein the heat sink pads are disposed such that three to ten battery cells of the plurality of battery cells are interposable therebetween (the thermal interface material along with the heat dissipation member 500 disposed between the each cartridge, where each Cartridge can have more than one cells (paragraph [0103], [0008])).
Regarding claim 9, Ejiri further discloses wherein the plurality of battery cells accommodated in the tray are vertically arranged (battery cells 2, fig. 2).
Regarding claim 11, Ejiri further discloses a temperature control method of a secondary battery charging and discharging system that uses the secondary battery charging and discharging system of claim 1 (Abstract and see the rejection of claim 1).
Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ejiri et al. (US 2015/0270589), and Lee (US 2011/0059347) as applied to claim 1 above, and further in view of Zhu et al. (US 2010/0021810), herein after Zhu.
Regarding claim 2, Ejiri in view of Lee discloses the system of claim 1. Although Ejiri does disclose the insulating plate is made of foam material, however, they are silent about the insulating plate is made of more specifically at least one material of nitrile butadiene rubber, natural rubber, fluorine rubber, high-cis polybutadiene rubber (HBR), styrene butadiene rubber, chloroprene rubber, ethylene propylene rubber (ethylene propylene terpolymers (EPDM)), or silicone rubber.
Zhu discloses the insulating plate is made of more specifically at least one material of nitrile butadiene rubber, natural rubber, fluorine rubber, high-cis polybutadiene rubber (HBR), styrene butadiene rubber, chloroprene rubber, ethylene propylene rubber (ethylene propylene terpolymers (EPDM)), or silicone rubber (the insulating layer may be formed from a plastic (e.g., PFA, PES, modified PP, or the like), rubber (e.g., EPDM, styrene-butadiene rubber, or the like), resin (epoxy resin, phenolic aldehyde modified epoxy resin, phenolic modified epoxy resin, or the like), paragraph [0165]).
It would have been obvious to one of ordinary skill in the art, before the effective filing date of claimed invention to modify Ejiri’s system to have an insulating plate made of rubber material as taught by Zhu, in order to have thermal stability in battery storage module.
Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ejiri et al. (US 2015/0270589), and Lee (US 2011/0059347) as applied to claim 1 above, and further in view of Chae et al. (US 2022/0216459), herein after Chae.
