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.
Claim(s) 2-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over XIAO et al. WO-2023024121-A1 in view JI et al CN-210467930-U.
XIAO teaches a battery cell as described in the rejection recited hereinabove. With respect to claim 2, XIAO teaches a first terminal electrically connected to the first electrode plate (terminal 211 is connected to a corresponding electrode; Fig. 13; See conventional electrode/terminal connection in Fig. 4) and a second terminal electrically connected to the second electrode plate (terminal 211 is connected to a corresponding electrode; Fig. 13; See conventional electrode/terminal connection in Fig. 4), wherein the cap plate comprises a safety vent (safety vent on cap plate 20;Fig. 4; Examiner Note: Fig 4 is relied upon to show the interior of conventional prismatic batteries), and wherein the support surface comprises a hole overlapping the first terminal and the second terminal (first terminal and the second terminal holes; Fig. 13 ).

XIAO does not teach or suggest: a groove overlapping the safety vent (claim 2); a length of the side of the protective layer is 10% to 50% of the width of the case (claim 3); a thickness of the protective layer is 0.1 mm to 3 mm (claim 4).
JI teaches that it is well known in the art to employ: a groove overlapping the safety vent (box cover 3 is provided with a vent groove; teaching claim 4; claim 2).
XIAO and JI are analogous art from the same field of endeavor, namely fabricating battery protective structures.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to employ the vent groove overlapping the safety vent of JI, in the battery cell of XIAO, in order to vent excess gas. The skilled artisan recognizes that the vent in battery cells cannot be blocked by protective structures, and a release mechanism must be employed to prevent damage.
With respect to a length of the side of the protective layer is 10% to 50% of the width of the case (claim 3); it would have been obvious in the battery cell of XIAO in view of JI, as rearrangement of essential working parts of a device is prima facie obvious. More specifically, shifting the position of parts within a device will not render the device patentable if the position change does not alter the device’s operation. See In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950). MPEP 2144.04. Furthermore, "where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." See In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). The discovery of an optimum value of a known result effective variable, without producing any new or unexpected results, is within the ambit of a person of ordinary skill in the art. See In re Boesch, 205 USPQ 215 (CCPA 1980) (see MPEP § 2144.05, II.).
With respect to a thickness of the protective layer is 0.1 mm to 3 mm (claim 4); it would have been obvious in the battery cell of XIAO in view of JI, as a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Furthermore, "where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." See In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). The discovery of an optimum value of a known result effective variable, without producing any new or unexpected results, is within the ambit of a person of ordinary skill in the art.

XIAO, JI and YAO are analogous art from the same field of endeavor, namely fabricating battery protective structures.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to employ the second protective layer is disposed under the case taught by YAO, on the battery case of XIAO in view of JI, to increase protection of the battery on the bottom side. The skilled artisan recognizes all sides of the battery need protection, and the bottom is vulnerable to damage.
With respect to the first protective layer being greater than a thickness of the second protective layer (claim 8); it would have been obvious in the battery cell of XIAO, in view of JI and YAO, as a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955).
With respect to a length of the first side being longer than a length of the second side (claim 9); it would have been obvious in the battery cell of XIAO, in view of JI and YAO, as a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955).
With respect to the first protective layer and the second protective layer comprising different materials (claim 10); it would have been obvious in the battery cell of XIAO, in view of JI and YAO, as the selection of a known material based on its suitability for its intended use supported a prima facie obviousness determination in Sinclair & Carroll Co. v.
