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.
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.
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.
Claims 3 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over the machine translation of Yamaguchi (JP 2015185535 A) and further in view of Seong (US 20150064535 A1).
Regarding claim 3, Yamaguchi teaches the battery module according to claim 2.
Yamaguchi does not teach wherein the at least an end portion of the fin body protrudes toward an inner surface of the housing rather than towards the plurality of battery cells.
Seong, in the same field of endeavor, batteries, teaches wherein the at least an end portion of the fin body protrudes toward an inner surface of the housing rather than towards the plurality of battery cells (Seong, Fig. 3, item 130 [cooling plates] extend past the battery cells [item 110]).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have extended Yamaguchi’s fin body, as taught by Seong, in order to discharge heat to the outside, as taught by Seong (para. 0014 [discharge heat from the thermal conduction part to the outside to perform cooling]).
Regarding claim 5, modified Yamaguchi teaches the battery module according to claim 3, and Yamaguchi teaches wherein the insulating cap is spaced apart from the inner surface of the housing (Yamaguchi, Fig. 2, item 22 is spaced apart from the surface of item 30- which is mounted in the apparatus per para. 0036), and the insulating cap is located closer to the inner surface of the housing than the plurality of battery cells (Modified Yamaguchi teaches that the fin body protrudes/extends past the battery cells – see claim 3 above).
Claims 6 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over the machine translation of Yamaguchi (JP 2015185535 A) and further in view of Kardasz (US 20120088140 A1) and Kim (US 20040091770 A1).

Kardasz, in the same field of endeavor, batteries, teaches wherein at least an end portion of the fin body comprises a coupling end having a loop shape (Kardasz, Fig. 21B) (Kardasz, para. 0067, [hook-shaped edge functioning as a cooling fin]).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have shaped the end portion of Yamaguchi’s cooling fin into a loop/hook shape, as taught by Kardasz, in order to increase the radiating surface area without increasing the overall breadth of the design (Kardasz, para. 0066, [the plate may be modified at its periphery to … increase the radiating surface area without increasing the overall breadth of the design]).
Modified Yamaguchi does not teach that the insulating cap comprises a coupling hook, and wherein a shape of the coupling hook is complementary to the loop shape of the coupling end of the at least an end portion of the fin body.
Kim, teaches that the insulating cap (member) has a shape that can be easily manufactured in various shapes by an insert-injection mold (Kim, para. 0045).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have manufactured modified Yamaguchi’s insulating cap by injection molding the insulating material into a shape, as taught by Kim, in order to complement its adjacent structures (Kim, para. 0040, [an insulating molding resin is injected into the mold to fill the space between the (one adjacent structure) cap plate and the (second adjacent structure) electrode port and form the insulating member therein]), as taught by Kim.
Therefore, modified Yamaguchi teaches wherein a shape of the coupling hook is complementary to the loop shape of the coupling end of the at least an end portion of the fin body.

Therefore, modified Yamaguchi teaches that the convex and concave portions are alternately arranged in a direction parallel to a longitudinal direction of each of the plurality of battery cells (Yamaguchi, the longitudinal direction of the cells is in the z direction. Fig. 2 of Yamaguchi indicates the z direction. This is analogous to the direction to the convex and concave potions shown in Fig. 21B of Kardasz) (See below).
Claims 7 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over the machine translation of Yamaguchi (JP 2015185535 A) and further in view of Hoerpel (US 20130122330 A1).
Regarding claim 7, Yamaguchi teaches the battery module according to claim 1.
Yamaguchi teaches wherein the housing further comprises a heat dissipating element (Yamaguchi, Fig. 2, item 31), wherein the heat dissipating element is in contact with the at least one cooling fin (Yamaguchi, Fig. 2, item 31 is in contact with item 22), and wherein the insulating cap is inserted into the heat dissipating element (Yamaguchi, Fig. 2, item 22 is inserted into item 31).

It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have made Yamaguchi’s heat dissipating element out of either a silicone or epoxy resin. The simple substitution of a known element (silicone) for another (epoxy resin) would achieve the predictable result of enabling heat dissipation, as disclosed by Yamamoto. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 415-421, 82 USPQ2d 1385, 1395-97 (2007).
Regarding claim 8, modified Yamaguchi discloses the battery module according to claim 7, wherein the heat dissipating resin (Fig. 3, item 31) is coated on an inner surface of the housing to a predetermined height (Fig. 3, item 31 is at a predetermined height of item 30 as shown in Fig. 3).
Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over the machine translation of Yamaguchi (JP 2015185535 A) and further in view of Hoerpel (US 20130122330 A1) and Jang (US 20220271364 A1).

It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have added a thermal conductive resin layer covering the lower surface of the battery cell stack to Yamaguchi’s cell stack, as taught by Jang, in order to cool heat generated in the battery cell stack (Jang, para. 0007)
Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over the machine translation of Yamaguchi (JP 2015185535 A) and further in view of Oogami (US 20040050414 A1).
Regarding claim 11, Yamaguchi discloses the battery module according to claim 1, wherein the plurality of battery cells are pouch-type cells (para. 0014, [flat cells]).
Yamaguchi is silent regarding:
each of the plurality of battery cells comprises a receiving portion which accommodates an electrode assembly, a sealing portion surrounding the receiving portion, and an electrode lead extending from the sealing portion to the outside of the battery cell, wherein the electrode lead is connected to the electrode assembly, and wherein the insulating cap is formed in a direction parallel to a direction in which the electrode lead extends.
Oogami, in the same field of endeavor, batteries teaches battery cells comprising
receiving portion (Oogami, Fig. 7A, item 10a, thick portion) which accommodates an electrode assembly (Oogami, para. 0041, [the battery cell houses the stacked electrode item 11])
a sealing portion surrounding the receiving portion (Oogami, Fig. 7A, item 10b, thin portion), and
an electrode lead extending from the sealing portion to the outside of the battery cell (Oogami, Fig. 7A, items 14 and 15)
wherein the electrode lead is connected to the electrode assembly (Oogami, Fig. 7A shows the connection)
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have utilized a flat cell designed with a receiving portion and sealing portion, as taught by Oogami, in order to house the electrode, as taught by Oogami (para. 0041).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have the electrode leads extend from the cell body, as taught by Oogami, in order to connect the leads to an external part without concern for the rigidity of the cell, as taught by Oogami (para. 0064).
Modified Yamaguchi teaches and wherein the insulating cap is formed in a direction parallel to a direction in which the electrode lead extends (Oogami, Fig. 7A, the electrode lead direction is analogous to the instant).
Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over the machine translation of Yamaguchi (JP 2015185535 A) and further in view of Oogami (US 20040050414 A1) and Horie (US 20030008205 A1).
Regarding claim 12, Yamaguchi teaches the battery module according to claim 2, wherein a material of the fin body is an aluminum metal (para. 0015, aluminum).
Yamaguchi does not teach that a material of the insulating cap is a rubber material.
Horie teaches that a material of the insulating material for its heat mediating structure is a rubber material (Horie, para. 0037, [in the case of applying an insulating material for the heat mediating structure …. the insulting material (can be) silicon rubber]).
It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to have made Yamaguchi’s insulating cap/material from rubber, as taught by Horie, in order to eliminate a necessity of introducing other insulating means, as taught by Horie (para. 0038).
