With respect to claim 9, each of the plurality of frame units (4; Fig. 16) includes one or a plurality of bipolar plates (1; Fig. 16) disposed between the cell members adjacent to each other in the stacking direction (positive electrode active material 2; negative electrode active material 3 [0108]; Fig. 16); a first end plate disposed at one end in the stacking direction of a plurality of the cell members (first end plate; Fig. 16, below) and a second end plate disposed at an other end in the stacking direction (second end plate; Fig. 16, below) , and a plurality of spacers disposed between the bipolar plates adjacent to each other in the stacking direction (spacer; Fig. 16 below), between the first end plate and the bipolar plate (spacer between bipolar plate and first end plate; Fig. 16 below) , and between the second end plate and the bipolar plate (spacer between bipolar plate and second end plate Fig. 16 below) ; a plurality of cells individually housing the plurality of cell members is formed by the one or plurality of bipolar plates (bipolar plate framed and sandwiched between the cathode and anode, 2, 3l Fig. 16 below), the first end plate and the second end plate, and the plurality of spacers (spacers and bipolar plates between end plates; Fig. 16); water sealing material is disposed in the groove (groove body component, ABS, PP, PVC, rubber, [0066]) PNG media_image2.png 860 895 media_image2.png Greyscale LIU does not teach or suggest: a groove being formed on outer side surfaces of frame units adjacent to each other in the stacking direction, the groove opening to the outer side surfaces (claim 1); the joining surface formed on an other surface in the stacking direction of the first end plate and the joining surface formed on one surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; the joining surface formed on one surface in the stacking direction of the bipolar plate and the joining surface formed on an other surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; the joining surface formed on an other surface in the stacking direction of the bipolar plate and the joining surface formed on one surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; the joining surface formed on one surface in the stacking direction of the second end plate and the joining surface formed on an other surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; and the groove is formed on an outer side surface of the first end plate and an outer side surface of the spacer adjacent to each other in the stacking direction, an outer side surface of the spacer and an outer side surface of the bipolar plate adjacent to each other in the stacking direction, and an outer side surface of the second end plate and an outer side surface of the spacer adjacent to each other in the stacking direction (claim 9); the groove communicating between the joining surface formed on one surface in the stacking direction of the bipolar plate and the joining surface formed on the other surface in the stacking direction of the spacer, and the groove communicating between the joining surface formed on the other surface in the stacking direction of the bipolar plate and the joining surface formed on one surface in the stacking direction of the spacer are an identical common groove communicating with each other (claim 15). Wang teaches that it is well known in the art to employ: a groove being formed on outer side surfaces of frame units adjacent to each other in the stacking direction, the groove opening to the outer side surfaces (Fig, 1; claim 1). PNG media_image3.png 320 1009 media_image3.png Greyscale 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 a groove being formed on outer side surfaces of frame units adjacent to each other in the stacking direction, the groove opening to the outer side surfaces of Wang, in the bipolar battery of LIU, in order to increase the sealing surface area, and thus structural integrity of the seal. The skilled artisan recognizes that a larger sealing area improves strength of the seal. With respect to joining surface formed on an other surface in the stacking direction of the first end plate and the joining surface formed on one surface in the stacking direction of the spacer being adjacent to each other in the stacking direction and joined to each other by the joining material; the joining surface formed on one surface in the stacking direction of the bipolar plate and the joining surface formed on an other surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; the joining surface formed on an other surface in the stacking direction of the bipolar plate and the joining surface formed on one surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; the joining surface formed on one surface in the stacking direction of the second end plate and the joining surface formed on an other surface in the stacking direction of the spacer are adjacent to each other in the stacking direction and joined to each other by the joining material; and the groove is formed on an outer side surface of the first end plate and an outer side surface of the spacer adjacent to each other in the stacking direction, an outer side surface of the spacer and an outer side surface of the bipolar plate adjacent to each other in the stacking direction, and an outer side surface of the second end plate and an outer side surface of the spacer adjacent to each other in the stacking direction (claim 9); it would have been obvious to form sealing grooves in sealing communication on the joining surfaces, other surfaces, one surface, and outer side surfaces in the stacking direction as taught by LIU in view of Wang above, in the bipolar plates, spacers and first and second endplates; in order to increase the sealing surface area, and thus improve structural integrity of the seal. The skilled artisan recognizes that a larger sealing area improves strength of the seal. The sealing groove arrangement necessitated by claim 9 is placed in each layer of the spacers, bipolar plates and end plates that are sealingly adjacent, and thus duplication of essential working parts of a device is prima facie obvious. See In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). Lastly, rearrangement of essential working parts of a device is prima facie obvious. See In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950). With respect to the groove communicating between the joining surface formed on one surface in the stacking direction of the bipolar plate and the joining surface formed on the other surface in the stacking direction of the spacer, and the groove communicating between the joining surface formed on the other surface in the stacking direction of the bipolar plate and the joining surface formed on one surface in the stacking direction of the spacer are an identical common groove communicating with each other (claim 15); it would have been obvious to form sealing grooves on the joining surfaces, one surfaces, and other surfaces as taught by LIU in view of Wang above, in the bipolar plates and spacers; in order to increase the sealing surface area, and thus structural integrity of the seal. The skilled artisan recognizes that a larger sealing area improves strength of the seal. The sealing groove arrangement necessitated by claim 15 is placed in each layer of the spacer and bipolar that are sealingly adjacent, and thus duplication of essential working parts of a device is prima facie obvious. See In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). Lastly, rearrangement of essential working parts of a device is prima facie obvious. See In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950).
