Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The amendment filed 7/10/23 has been considered and entered. Claims 1-5 remain in the application for prosecution thereof. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-5 are rejected under 35 U.S.C. 102(a)(2) as being clearly anticipated by Yamaguchi et al. (2020/0136097). Yamaguchi et al. (2020/0136097) teaches a cylindrical battery can (18) including an electrode body and a sealing body (20) as depicted in Fig. 1. Yamaguchi et al. (2020/0136097) teaches a second cover plate (21) fixed to a first cover plate (25) with an inner gasket (24) and a valve disc (23) being compressed between the first (25) and second (21) cover plates and being in the direction of flow. The first cover plate has a hollow disk-shaped pattern with a first sidewall and a portion extending downward from an edge portion of the first side wall and a bottom portion connected to the sidewall portion with through/venting holes (22a). The second plate (21) also having communicating holes therethrough (Fig. 2). Regarding claims 2 and 4, Yamaguchi et al. (2020/0136097) teaches and depicts the through holes of the first cover plater (25) being in a vertical and horizontal direction with respect to the axis line. Regarding claim 3, Yamaguchi et al. (2020/0136097) teaches a second side wall and a second hole/vent passing through in the direction of fluid flow with the valve disc between the hole and fluid flow. Regarding claim 5, Yamaguchi et al. (2020/0136097) teaches a cylindrical storage battery including spiral stacking of positive electrode, negative electrode and separator, an outer can (18), a positive electrode terminal (11a) and a sealing body (21) (Figs. 1 and 2). Claims 1-5 are rejected under 35 U.S.C. 102(a)(2) as being clearly anticipated by Iwaizono et al. (6,524,739). Iwaizono et al. (6,524,739) teaches a secondary battery including a sealing member (65) having a bottom plate (66) (claimed first cover plate) and a support plate (18) (claimed second cover plate) fixed to the bottom plate (66) having a gasket (19) (claimed elative valving element) compressed between the bottom plate (66) and the support plate (18). The sealing plate (66) includes a hollow disk portion having a first sidewall extending downward from an edge portion and a bottom wall connected to the first sidewall and having opening (66a) in a direction approaching the axis line. The support plate (18) also has a hole (18a) therein while the gasket (19) is disposed between the opening (66a) and the hole (18a) in a direction of fluid flow (abstract, col. 18, line 40 – col. 19, line 14 and Fig. 14). Regarding claims 2 and 4, Iwaizono et al. (6,524,739) teaches and depicts the opening (66a) and the hole (18a) being in a vertical and horizontal direction with respect to the axis line. Regarding claim 3, Iwaizono et al. (6,524,739) teaches a second side wall and a second hole/vent passing through in the direction of fluid flow with the gasket (19) between the hole and fluid flow. Regarding claim 5, Iwaizono et al. (6,524,739) teaches a cylindrical storage battery which would include but not depicted a spiral stacking of positive electrode, negative electrode and separator, an outer can (15), a positive electrode terminal and a sealing body (65) (Figs. 1 and 2).
