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.
Claims 8 is rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. (US20230238610A1).
As to claim 8 Yang et al. (‘8610) discloses the battery pack according to claim 7 (see discussion of claim 7).
Yang et al. (‘8610) also discloses the first orifice 311 in the support component 13 is arranged corresponding to the pressure relief region 130 of the thermal management component 13 in Par. 217. The first orifice 311 may be in communication with the pressure relief region 130 of the thermal management component 13 and the first orifice 311 may have a cross-sectional area not less than the area of the pressure relief region 130, to achieve a good conduction effect of the first orifice 311 on the emissions in Par. 218.
Yang et al. (‘8610) does not explicitly disclose wherein a number of the receiving through holes is less than a number of the pressure relief through holes and one of the receiving through holes is disposed corresponding to plural of the pressure relief through holes, or the number of the receiving through holes corresponds to the number of the pressure relief through holes, and the receiving through holes and the pressure relief through holes are arranged in one-to-one.
It would have been obvious for a person with ordinary skills in the art to modify the first orifice in the supporting member from Yang et al. (‘8610) so that the number of first orifices corresponds to the number of pressure relief regions and the first orifices are arranged one-to-one with the pressure relief regions as taught in Yang et al. (‘8610) in order to further improve the good conduction effect of the first orifice on the emissions in Par. 218.
Claims 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. (US20230238610A1) in view of Deng et al. (US20240088513A1).

The first plate 1231 and the fifth plate 131 are extending in opposite directions as shown in Fig. 17.
Both Yang et al. (‘8610) and Deng et al. are analogous in the field of battery packs supporting structures, it would have been obvious for a person with ordinary skills in the art to modify the support member in Yang et al. (‘8610) to include the two lifting portions extending away from each other as taught by Deng et al. in order to save costs and simplify the mounting process as taught by Deng et al. in Par. 94.
In any event, changes to size and shape of the prior art venting structure are an obvious modification, absent evidence to the contrary (see MPEP 2144.04 Part IV).

(‘0651) in Par. 186.
As to claim 12 Yang et al. (‘8610) in view of Yang et al. (‘0651) discloses the battery pack according to claim 11 (see discussion of claim 11), wherein each of the separating beams comprises a top portion extending in the width direction of the battery pack (see discussion of claim 11, and see Fig. 12b in Yang et al.

(‘0651) discloses the hollow beams 113a directly uses the thermal management component 13 as its bottom wall in Par. 182, in Fig. 12b and the emissions collected by the collection chamber 11a enter the hollow beam 113a through the pressure relief region and are discharged to the outside of the box 11 through the fifth pressure balance mechanism in Par. 177).
As to claim 13 Yang et al. (‘8610) in view of Yang et al. (‘0651) discloses the battery pack according to claim 11 (see discussion of claim 11), wherein the discharge through holes are provided with waterproof and breathable valves (see e.g. Yang et al. (‘8610) discloses the pressure relief mechanism may take the form of an anti-explosion valve, an air valve, a pressure relief valve, a safety valve, etc. in Par. 93).
Claims 15-16 are rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. (US20230238610A1) in view of Kurpiel. (US20230402669A1).
As to claim 15 Yang et al. (‘8610) discloses the battery pack according to claim 1 (see discussion of claim 1).

The support structure 13 is provided with a protective layer 133 in the region of the first side 137, in particular for protecting against heat and/or abrasive material and or chemical influences in Par. 97. The protective layer 133 may be a layer applied to the wall, for example mica sheets, in Par. 97.
Both Yang et al. (‘8610) and Kurpiel et al. are analogous in the field of battery pack support structures, it would have been obvious for a person with ordinary skills in the art to modify the support members in Yang et al. (‘8610) to include a protective layer provided on at least one of a side of the base portion facing the pressure relief through holes and a side of the supporting portion close to the base portion as taught in Kurpiel et al. in order to protect the support members from heat, abrasive media, and chemical influences as taught by Kurpiel et al. in Par. 97.
