In Regards to Claim 1:
Kwon discloses an all-solid-state battery comprising a columnar battery cell (cable-type secondary battery, 100) including a positive electrode support (inner current collector, 110), positive electrode active material (inner electrode active material layer, 120), a solid electrolyte layer (separation layer, 130), a negative active material (outer electrode active material layer, 140), a negative electrode support (outer current collector, 150), and a protection coating (160) which are sequentially stacked from a center of the battery cell (cable-type secondary battery, 100) (Figure 1, [0020, 0037, 0061-0062]). Kwon further discloses that the protection coating (160) is an insulator which protects the columnar battery cell (cable-type secondary battery, 100) from moisture in the air and external impacts (Figure 1, [0072]). Kwon further discloses that in an alternate embodiment, the active material (electrode active material layer, 120/140) and the electrode support (current collector, 110/150) may be alternately arranged such that the active material (electrode active material layer, 120/140) is in an innermost position compared to the electrode support (current collector, 110/150) (Figure 1, [0042]). Kwon further discloses that the columnar battery cell (cable-type secondary battery, 100) has a first surface (“front” surface) and a second surface (“rear” surface) opposing each other in a first direction (in and out of page in Figure 1) parallel to a central axis of the battery cell (cable-type secondary battery, 100) (Figure 1, [0018]). Kwon further discloses a third surface (“left” surface) and a fourth surface (“right” surface) opposing each other in a second direction (left to right of page in Figure 1), different the first direction (in and out of page in Figure 1) (Figure 1). Kwon further discloses a fifth surface (“upper” surface) and a sixth surface (“lower” surface) opposing each other in a third direction (up and down page in Figure 1), different from the first direction (in and out of page in Figure 1) and the second direction (left to right of page in Figure 1) (Figure 1).
Kwon is deficient in disclosing 1) the all-solid-state battery comprises a battery body including a plurality of columnar battery cells; 2) a groove portion and a plurality of connection members disposed on the battery cells, wherein the groove portion is disposed on one surface of the battery cell in the third direction; and 3) a positive electrode terminal connected to one or more of the plurality of connection members and disposed on the fifth surface of the battery body; and a negative electrode terminal connected to another one or more of the plurality of connection members and disposed on the sixth surface of the battery body.
Ellis-Monaghan discloses an embodiment of an all-solid-state battery (3D-integrated all-solid-state battery) comprising a battery body including a plurality of columnar battery cells (104) (Figure 1, [0024]). Ellis-Monaghan further discloses that in such an embodiment, a positive electrode terminal (current collector, 106) and a negative electrode terminal (current collector, 108) may be used on opposite ends of the all-solid-state battery (3D-integrated all-solid-state battery) as a means to connect to an electronic device (Figure 1, [0024]). Ellis-Monaghan further discloses that in an alternate embodiment, a plurality of connection members (fuse wires, 502/504, and vias, 506) are used in addition to the electrode terminal (current collectors, 106) to connect a plurality of battery cells (sub-array, 316/318/etc.) together, wherein the connection members (fuse wires, 502/504, and vias, 506) are disposed on the battery cells (sub-array, 316/318/etc.) and are electrically connected to the electrodes (208/202) (Figures 2, 5/6, [0030, 0035]). Ellis-Monaghan further discloses that the battery cells (sub-array, 316/318/etc.) include a protective layer (electrically insulating material, 602) which serves to cover and protect the positive electrode terminal (current collector, 106) (Figure 6, [0036]). Ellis-Monaghan further discloses that the protective layer (electrically insulating material, 602) possesses grooves (506) through which the connection members (fuse wires, 502/504, and vias, 506) form an electrical connection with the positive electrode terminal (current collector, 106) (Figure 6, [0036]).
Therefore, it would be obvious to one of ordinary skill in the art at the time of the filing of the invention to incorporate a plurality of the battery cells of Kwon into a battery body as taught by Ellis-Monaghan, as it is known in the art as a common configuration to have a plurality of battery cells electrically connected together to form a battery body in order to scale the amount of electrical output able to be provided by a battery configuration, as taught by Ellis-Monaghan.

Response to Arguments
Applicant's arguments filed 12/01/2025 have been fully considered but they are not persuasive.
The Applicant argues that the previously cited prior art references Kwon et al. (US 2014/0170456 A1) and Ellis-Monaghan (US 2013/0084476 A1) combined fail to teach a groove portion disposed on one surface of the battery cell in the third direction.
The examiner respectfully disagrees. As detailed above in the rejection of Claim 1, Kwon discloses an all-solid-state battery comprising a columnar battery cell (cable-type secondary battery, 100) (Figure 1, [0020, 0037, 0061-0062]). Kwon further discloses that the columnar battery cell (cable-type secondary battery, 100) has a first surface (“front” surface) and a second surface (“rear” surface) opposing each other in a first direction (in and out of page in Figure 1) parallel to a central axis of the battery cell (cable-type secondary battery, 100) (Figure 1, [0018]). Kwon further discloses a third surface (“left” surface) and a fourth surface (“right” surface) opposing each other in a second direction (left to right of page in Figure 1), different the first direction (in and out of page in Figure 1) (Figure 1). Kwon further discloses a fifth surface (“upper” surface) and a sixth surface (“lower” surface) opposing each other in a third direction (up and down page in Figure 1), different from the first direction (in and out of page in Figure 1) and the second direction (left to right of page in Figure 1) (Figure 1).
Kwon is deficient in disclosing 1) the all-solid-state battery comprises a battery body including a plurality of columnar battery cells; 2) a groove portion and a plurality of connection members disposed on the battery cells, wherein the groove portion is disposed on one surface of the battery cell in the third direction; and 3) a positive electrode terminal connected to one or more of the plurality of connection members and disposed on the fifth surface of the battery body; and a negative electrode terminal connected to another one or more of the plurality of connection members and disposed on the sixth surface of the battery body.
Ellis-Monaghan discloses an embodiment of an all-solid-state battery (3D-integrated all-solid-state battery) comprising a battery body including a plurality of columnar battery cells (104) (Figure 1, [0024]). Ellis-Monaghan further discloses that in such an embodiment, a positive electrode terminal (current collector, 106) and a negative electrode terminal (current collector, 108) may be used on opposite ends of the all-solid-state battery (3D-integrated all-solid-state battery) as a means to connect to an electronic device (Figure 1, [0024]). Ellis-Monaghan further discloses that in an alternate embodiment, a plurality of connection members (fuse wires, 502/504, and vias, 506) are used in addition to the electrode terminal (current collectors, 106) to connect a plurality of battery cells (sub-array, 316/318/etc.) together, wherein the connection members (fuse wires, 502/504, and vias, 506) are disposed on the battery cells (sub-array, 316/318/etc.) and are electrically connected to the electrodes (208/202) (Figures 2, 5/6, [0030, 0035]). Ellis-Monaghan further discloses that the battery cells (sub-array, 316/318/etc.) include a protective layer (electrically insulating material, 602) which serves to cover and protect the positive electrode terminal (current collector, 106) (Figure 6, [0036]). Ellis-Monaghan further discloses that the protective layer (electrically insulating material, 602) possesses grooves (506) through which the connection members (fuse wires, 502/504, and vias, 506) form an electrical connection with the positive electrode terminal (current collector, 106) (Figure 6, [0036]).
Therefore, it would be obvious to one of ordinary skill in the art at the time of the filing of the invention to incorporate a plurality of the battery cells of Kwon into a battery body as taught by Ellis-Monaghan, as it is known in the art as a common configuration to have a plurality of battery cells electrically connected together to form a battery body in order to scale the amount of electrical output able to be provided by a battery configuration, as taught by Ellis-Monaghan.
Upon the above modification, it would be further obvious to the skilled artisan to include in the all-solid-sate battery of modified Kwon, a plurality of connection members, a positive electrode terminal, and a negative electrode terminal, wherein the positive electrode terminal and negative electrode terminals are connected to the battery body via the plurality of connection members, with the connection members being located on opposing sides of the battery body in alignment with the negative electrode terminal and positive electrode terminal, as it is known in the art as a useful configuration for connecting a plurality of battery cells to an external electronic device, as taught by Ellis-Monaghan. Furthermore, the selection of a known configuration based on its suitability for its intended use supports a prima facie obviousness determination (MPEP 2144.07).
Furthermore, upon the above modifications, it would be further obvious to the skilled artisan to select for the surfaces of the battery cell wherein the positive electrode terminal and negative electrode terminal are location, the fifth surface and the sixth surface, as such a configuration is one of a finite number of possible configurations that the terminals may have where they are on opposing sides of the battery, as taught by Ellis-Monaghan (MPEP 2143 I, E). For example, the positive electrode terminal and negative electrode terminal may only be on the first surface and second surface, the third surface and fourth surface, or the fifth surface and sixth surface, respectively.
In other words, Ellis-Monaghan is relied upon to teach 1) a scaling process to utilize a plurality of columnar battery cells within an all-solid-state battery, 2) a means of electrically connecting a plurality of cells together (in Ellis-Monaghan’s case, each “cell” being the sub-array, 316/318/etc.) via use of connecting members.
As such, the skilled artisan would appreciate that a groove portion is formed on the surface of the battery in the third direction, as the fifth surface and sixth surface are formed in the third direction, and when the electrode terminals and connection members are connected to the battery body at such locations, a groove must be formed in the inner electrode and outer electrode, respectively, at the point where the connection members and the electrodes make contact, as taught by Ellis-Monaghan..
While the examiner appreciates that the structure of the instant invention and the structure resulting from the modification of Kwon in view of Ellis-Monaghan are different, however the examiner maintains that the prior art meets the limitations of the instant claim as currently written. The examiner further notes that instant Claim 1 as currently written does not require that the positive electrode support is directly connected (i.e., in direct contact with) connection member.
The examiner further notes that amending the claim to further define the structure of the groove according to the instant figures could suitably overcome the prior art on record.
The Applicant further argues that the instant application was utilized as a blueprint to reconstruct the prior art to arrive at the claimed invention, as the prior art is silent to a groove portion.
In response to Applicant's argument that the examiner's conclusion of obviousness is based upon improper hindsight reasoning, it must be recognized that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning. But so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made, and does not include knowledge gleaned only from the applicant's disclosure, such a reconstruction is proper. See In re McLaughlin, 443 F.2d 1392, 170 USPQ 209 (CCPA 1971).
The Applicant further argues that applying the electrical configuration of Ellis-Monaghan to the battery of Kwon would render the intended purpose of Ellis-Monaghan unsatisfactory.
As detailed above, Ellis-Monaghan is simply relied upon to teach 1) a scaling process to utilize a plurality of columnar battery cells within an all-solid-state battery, 2) a means of electrically connecting a plurality of cells together (in Ellis-Monaghan’s case, each “cell” being the sub-array, 316/318/etc.) via use of connecting members. Even in the case that applying the scaling and electrical connection taught by Ellis-Monaghan to the battery of Kwon would not directly serve the intended purpose of Ellis-Monaghan does not render the instant claim not met by the prior art.
In addition to addressing the Applicant’s arguments above, in order to expedite prosecution of the application, the examiner has additionally included a new grounds of rejection in view of Kwon et al. (US 2014/0170456 A1), Ellis-Monaghan (US 2013/0084476 A1), Kim (US 2010/0227209 A1), and Kuroda et al. (US 2019/0027776 A1), detailed above.
