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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Honda et al. WO2020183795 (See English US 2021/0391617)
With respect to claim 1, Honda et al. discloses a battery 1300 comprising:
a power generation element that includes a plurality of unit cells 2200 each including a positive electrode layer 120/220, a negative electrode layer 110/210, and a solid electrolyte layer 130 located between the positive electrode layer 120/220 and the negative electrode layer 110/210, [0102-01113; Figure 4B]
wherein the plurality of unit cells 2200 are electrically connected in parallel [0103] and are stacked in a direction normal to a main surface of the power generation element [Figure 4B],

in the second side surface, each of the negative electrode layers 110/210 in the plurality of unit cells 2200 protrudes more than each of the positive electrode layers 120/220 in the plurality of unit cells 2200 such that second depressions and second projections arranged alternately in the direction normal to the main surface are provided, [Figure 4B]
each of the first depressions includes a first inclination surface that is inclined relative to the direction normal to the main surface and is an end surface of the negative electrode layer 110/210, [Figure 4B]
each of the second depressions includes a second inclination surface that is inclined relative to the direction normal to the main surface and is an end surface of the positive electrode layer 120/220, [Figure 4B] the battery further comprises:
a first conductive member 500 that is in contact with the first projections; and
a second conductive member 500 that is in contact with the second projections, (Current collecting leads 500 are connected to the respective exposed surfaces 300 of the negative electrode current collectors 210 or the positive electrode current collector of the battery cells 2200 by utilizing the laminating spaces 400) [0098-0108]
modification 3 of Embodiment 1 in Figure 4B does not specifically disclose one or a plurality of first insulating members that are arranged in the first depressions; one or a plurality of second insulating members that are arranged in the second depressions; [Figure 4B]
However, Figure 8 (Embodiment 2) shows modification 3 of Embodiment 1 may further include a sealing member 700 [0111]
Therefore Honda et al. discloses one or a plurality of first insulating members 700 that are arranged in the first depressions; one or a plurality of second insulating members 700 that are arranged in the second depressions; [Figure 8]
wherein the positive electrode layers 120/220 in the plurality of unit cells are electrically connected via the first conductive member 500, and
the negative electrode layers 110/210 in the plurality of unit cells are electrically connected via the second conductive member 500. [Figure 1B]
Therefore it would have been obvious to one of ordinary skill in the art as of the effective filing date of the invention to have modified Embodiment 1 of Honda et al. to include the insulating members of Embodiment 2 of Honda et al. in order to allow for sufficient spacing and increased safety.

With respect to claim 9, Honda et al. discloses wherein at least one of the first conductive member or the second conductive member includes a multilayer structure. [Figure 1B]
With respect to claim 10, Honda et al. disclose does not disclose wherein an outermost layer in the multilayer structure is a plating layer or a solder layer.
The further limitation regarding “a plating layer or a solder layer” is a product-by-process limitation that does not further limit the scope of the claim.
“[E]ven though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process.” In re Thorpe, 777 F.2d 695, 698, 227 USPQ 964, 966 (Fed. Cir. 1985).
With respect to claim 11, Honda et al. discloses a sealing member 700 that exposes a part of the first conductive member 500 [Figure 8] and a part of the second conductive member 500 and seals the power generation element. [Figure 8]
