The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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.
Claim(s) 1-3, 6, 7, 11, 13-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Qin (US20190245175) in view of Qin’ (US20190288256).
Regarding Claim 1, Qin discloses a battery module ([002]) comprising:
A battery cell stack comprising a plurality of battery cells (battery stack-20 formed of battery cells, [005]); and
A housing for the battery cell stack (housing-10, Fig. 2, [0054])
Front and rear end plates for covering front and rear surfaces, respectively, of the battery cell stack (first end plate-30 and second end plate-40 act as front and rear plates, Fig. 2, [005]),
Wherein at least one of the housings, the front-end plate or the rear end plate comprises a venting part for discharging gas and flame (module vent plate-70, [0073], Fig. 2).
Qin discloses wherein the venting part comprises a through hole formed in at least on of the housing, front end plate or the rear end plate (module vent plate defines a through hole on the front-end plate, Fig. 2).
Qin does not directly disclose a first cover part for the covering the through hole; and a first opening positioned on a side of the first cover part and in communication with the through hole such that the venting part has a shape that bends a discharge path of the gas and flame.
The examiner notes that that under the broadest reasonable interpretation of the claim language, that “bend a discharge path” can be any structure that adjusts the gas or flame to be directed in a nonlinear line.
Qin discloses a module vent plate-70 acts as venting part that bends a discharge path.
Qin’ discloses a vent structure that includes a through hole, a first cover part for covering the through hole and a first opening formed on a side of the first cover part and communicating with the through hole (vent hole-312, second vent plate-36 covers hole acting as first cover part, Fig. 2, [0086]). Qin’ teaches that this structure provides improved safety of the battery module ([0086]).
The examiner notes that the teachings of Qin’ are brought in to teach the modification of a cover part that covers a through and a first opening that is formed on a side of the first cover part. Therefore, since Qin already discloses a venting part that “bends a discharge path”, it would be obvious to one of ordinary skill in the art to modify Qin with the teachings of Qin’ to have wherein a first cover part for the covering the through hole; and a first opening positioned on a side of the first cover part and in communication with the through hole such that the venting part has a shape that bends a discharge path of the gas and flame. This modification would yield the expected results of improved safety of the battery module.
Regarding Claim 3, Qin in view of Qin’ discloses the limitations as set forth above. Qin does not directly disclose wherein an area of the first cover part is larger than an opening area of the through hole.
Qin’ discloses wherein an area of the first cover part is larger than an opening area of the through hole (Fig. 5 shows second vent plate-36 having larger area than through hole).
Therefore it would be obvious to one of ordinary skill in the art to modify the structure of Qin with the teachings of Qin’ to have wherein an area of the first cover part is larger than an opening area of the through hole.
Regarding Claim 6, Qin discloses the limitations as set forth above. Qin does not directly disclose wherein the venting part further comprises a second cover part for covering the through hole, wherein the second part is located opposite to the first cover part with respect to the through hole; and a second opening formed on a side of the second cover part and communicating with the through hole.
Qin’ discloses a second cover part covers the through hole on the opposite side of the first cover part (shielding member-60 acts as second cover part that covers a second opening of the through hole formed by a sinking portion-313 in communication with the through hole-312, Fig. 11, [0093]).
Therefore it would be obvious to one of ordinary skill in the art to modify the structure of Qin with the teachings of Qin’ to have wherein the venting part further comprises a second cover part for covering the through hole, wherein the second part is located opposite to the first cover part with respect to the through hole; and a second opening formed on a side of the second cover part and communicating with the through hole. This modification would yield the expected results of improved safety of the battery module.
Regarding Claim 7, Qin discloses the limitations as set forth above. Qin does not directly disclose wherein an area of the second cover part is larger than an opening area of the through hole.
Qin’ discloses wherein the second cover part is larger than an opening area of the through hole (sinking portion-313 and protection member-60 are larger in area than through hole, Fig. 11, Fig. 3, [0093]).
Regarding Claim 11, Qin discloses the limitations as set forth above. Qin further discloses wherein the venting part guides the discharge of gas and flam in a direction parallel to a surface of at least one of the housing (module vent frame is positioned so that the gas is discharged parallel to the housing, Fig. 2).
Regarding Claim 13, Qin discloses the limitations as set forth above. Qin further disclose a battery pack comprising the battery module according to claim 1 (it is the examiner’s position that absent a specific definition of a battery pack, that a battery module according to claim 1 meets the limitations of a being a battery pack that includes said battery module).
Regarding Claim 14, Qin discloses the limitations as set forth above.
Qin discloses wherein the first end plate comprises the venting part, and (first end plate-30 and second end plate-40 act as first and second end plates, Fig. 2, [005))
Qin modified by Qin’ discloses a first cover part that is connected to the venting part.
It is the examiner’s position that modified Qin would have the first cover part attached to the module vent portion of Qin, and thus would have the first cover part connected to the first end plate where the first opening is formed.
Therefore it would be obvious to one of ordinary skill in the art to modify the structure of Qin with the teachings of Qin’ to have wherein the first cover part is connected to the first end plate at a portion where the first opening is not formed.
Claim(s) 4,5 & 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Qin (US20190245175) in view of Qin’ (US20190288256) further in view of Egashira (US20210265700).
Regarding Claim 4 & 5, Qin in view of Qin’ discloses the limitations as set forth above. Modified Qin does not directly disclose wherein an opening direction of the through hole is different from an opening direction of the first opening, and wherein an opening direction of the through hole and an opening direction of the first opening are perpendicular to each other.
Egashira discloses a through hole that is offset from a first opening in a perpendicular direction (discharge valve-15 define through hole), Fig. 7, [0049], gas guide path-60, exhaust port-63 acts as first cover portion with first opening, [0098-0099]). Egashira teaches that this structure provides improved high-pressure gas discharge ([0100]).
Therefore, it would be obvious to one of ordinary skill in the art to modify Qin with the teachings of Qin’ and Egashira to have wherein an opening direction of the through hole is different from an opening direction of the first opening, and wherein an opening direction of the through hole and an opening direction of the first opening are perpendicular to each other. This modification would yield the expected result of improved high-pressure gas discharge.
Regarding Claim 10, Qin in view of Qin’ discloses the limitations as set forth above.
Qin does not directly disclose wherein the discharge path of the gas and flame is bent at least twice by the first cover part and the second cover part.
Egashira discloses a gas guide path that bends the gas discharge twice (gas guide path-60, includes one or more horizontal gas flow bending portions, [007]). Egashira teaches that this structure provides improved high-pressure gas discharge ([0100]).
Therefore, it would be obvious to one of ordinary skill in the art to modify Qin with the teachings of Qin’ and Egashira to have wherein the discharge path of the gas and flame is bent at least twice by the first cover part and the second cover part. This modification would yield the expected result of improved high-pressure gas discharge.
Regarding Claim 15, Qin in view of Qin’ discloses the limitations as set forth above.
Modified Qin does not directly disclose wherein the first cover part is spaced part from the through hole in a predetermined interval and wherein the first opening is formed by a space in which the first cover part is spaced apart from the through hole
Egashira discloses a through hole that is offset from a first opening in a perpendicular direction and a first opening that is formed by a space in which the first cover part is sapced apart from the through hole (discharge valve-15 define through hole), Fig. 7, [0049], gas guide path-60, exhaust port-63 acts as first cover portion with first opening, [0098-0099]). Egashira teaches that this structure provides improved high-pressure gas discharge ([0100]).
Therefore it would be obvious to one of ordinary skill in the art to modify the structure of Qin with the teachings of Egashira to have wherein the first cover part is spaced part from the through hole in a predetermined interval and wherein the first opening is formed by a space in which the first cover part is spaced apart from the through hole. This modification would yield the expected result of improved high-pressure gas discharge.
Claim(s) 8 & 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Qin (US20190245175) in view of Qin’ (US20190288256) in view of Hyung (KR20180113855, see Machine Translation for citations) (Provided on Applicant’s IDS filed on April 1st, 2024).
Regarding Claim 8 & 9, Qin in view of Qin’ discloses the limitations as set forth above.
Modified Qin does not disclose wherein an opening direction of the through hole is different from an opening direction of the second opening and wherein an opening direction of the through hole and an opening direction of the second opening are perpendicular to each other.
Hyung discloses a valve structure that includes a through hole, a second cover part with a second opening, and wherein the second cover part second opening is perpendicular to the through hole (flame filter part-154c provides through hole, lower vent 154b acts as second cover part, with 154b-1 denoting opening, Fig. 3/4a, [0055], [0057]). Hyung teaches that this structure provides improved stability and reliability of the battery ([0015]).
Therefore, it would be obvious to one of ordinary skill in the art to modify Qin with the teachings of Qin’ and Hyung to have wherein an opening direction of the through hole is different from an opening direction of the second opening and wherein an opening direction of the through hole and an opening direction of the second opening are perpendicular to each other. This modification would yield the expected result of improved stability and reliability of the battery.

Regarding Claim 12, Shaffer discloses the limitations as set forth above.
Qin does not directly disclose wherein the battery module further comprises an insulating cover located between the battery cell stack and at least one of the front end plate or rear end plate, wherein the venting part is formed in the at least one of the front end plate or rear end plate, and an insulating cover opening is formed at a position corresponding to the venting part of the insulating cover.
Pinon discloses a the battery module further comprises an insulating cover located between the battery cell stack and at least one of the front end plate or rear end plate (insulating polymer layer-90 on end plate, [0135]), wherein the venting part is formed in the at least one of the front end plate or rear end plate (end plates-92 acts a front and rear plate, [0135], vent disc-92 included on end plate, [0135]), and an insulating cover opening is formed at a position corresponding to the venting part of the insulating cover ([0135]). Pinon teaches that this structure provides improved longevity for the battery module ([0184]).
Therefore it would be obvious to one of ordinary skill in the art to modify Shaffer with the teachings of Pinon to have wherein the battery module further comprises an insulating cover located between the battery cell stack and at least one of the front end plate or rear end plate, wherein the venting part is formed in the at least one of the front end plate or rear end plate, and an insulating cover opening is formed at a position corresponding to the venting part of the insulating cover. This modified structure would yield the expected result of improved longevity for the battery module.
Response to Arguments
Applicant's arguments filed June 25th, 2026 have been fully considered but they are not persuasive.
Applicant argues that Qin in view of Qin’ does not disclose the amended limitation “a first cover part for the covering the through hole; and a first opening positioned on a side of the first cover part and in communication with the through hole such that the venting part has a shape that bends a discharge path of the gas and flame.”
Qin discloses wherein the venting part comprises a through hole formed in at least on of the housing, front end plate or the rear end plate (module vent plate defines a through hole on the front-end plate, Fig. 2).
Qin does not directly disclose a first cover part for the covering the through hole; and a first opening positioned on a side of the first cover part and in communication with the through hole such that the venting part has a shape that bends a discharge path of the gas and flame.
The examiner notes that that under the broadest reasonable interpretation of the claim language, that “bend a discharge path” can be any structure that adjusts the gas or flame to be directed in a nonlinear line.
Qin discloses a module vent plate-70 acts as venting part that bends a discharge path.
Qin’ discloses a vent structure that includes a through hole, a first cover part for covering the through hole and a first opening formed on a side of the first cover part and communicating with the through hole (vent hole-312, second vent plate-36 covers hole acting as first cover part, Fig. 2, [0086]). Qin’ teaches that this structure provides improved safety of the battery module ([0086]).
The examiner notes that the teachings of Qin’ are brought in only to teach the modification of a cover part that covers a through and a first opening that is formed on a side of the first cover part, as Qin already discloses a “bent discharge path”. The teachings of Qin’ when applied to Qin would not disrupt the “bent discharge path” already present in Qin.
Therefore applicant’s arguments regarding the Qin in view of Qin’ combination are not commensurate in scope with the claim language.
Therefore, since Qin already discloses a venting part that “bends a discharge path”, it would be obvious to one of ordinary skill in the art to modify Qin with the teachings of Qin’ to have wherein a first cover part for the covering the through hole; and a first opening positioned on a side of the first cover part and in communication with the through hole such that the venting part has a shape that bends a discharge path of the gas and flame. This modification would yield the expected results of improved safety of the battery module.
