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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2 and 4 are rejected under 35 U.S.C. 102(1) as being anticipated by KR20130071638A, hereinafter 638’. As to claim 1, 638’ discloses in figures 1-9 (figure 7 is reproduced below):- PNG media_image1.png 558 316 media_image1.png Greyscale a charging and discharging device for a secondary battery [see above element 10], comprising: a body portion [10]; and a head portion located under the body portion [the head portion is where the current pins and voltage pin are mounted; see figure above] , wherein the head portion comprises a pin mounting portion [see figure 2, element 12 is mounting potion; see also ¶0018] that is configured to be bound to an upper portion or a lower portion of the secondary battery [see figure above], wherein the pin mounting portion comprises a current pin [element 20A, see ¶0018] and a voltage pin [element 20B; see ¶0018], wherein each of the current pin and the voltage pin each comprises a plurality of projections [see figure 8, and contact protrusions 22; see also ¶0022] , and wherein an area where the current pin is formed is larger than an area where the voltage pin is formed [the current pins as shown in figure 2 covers larger area than the voltage pin]. As to claim 2, 638’ discloses in figure above, wherein: the current pin [pin 20A] is formed in a maximum area [pin 20A covers larger area] that can be formed in the pin mounting portion [mounting portion 12], and the voltage pin [20B] is formed in the a minimum area that can be formed in the pin mounting portion [the voltage pin covers small area than the current pins]. As to claim 4, 638’ discloses in figure above, wherein: the voltage pin [20B] is formed in a center of the pin mounting portion [see figure above], and the current pin [20A] is formed at a periphery of the pin mounting portion so as to surround the voltage pin. As to claim 6, 638’ discloses in figure above, wherein: the current pin and the voltage pin are spaced apart from each other by a first distance [see figure above]. Claim Rejections - 35 USC § 103 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 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 3, 5 and 7-11 are rejected under 35 U.S.C. 103 as being unpatentable over 638’. As to claim 3, 638’ discloses in figure above, the current pin and the voltage pin are covering the are of the mounting portion. However, 638’ does not disclose explicitly, wherein: the current pin is formed in an area of 70% or more and 99% or less of a total area of the pin mounting portion, and the voltage pin is formed in an area of 1% or more and 15% or less relative of the total area of the pin mounting portion. It would have been obvious to one having ordinary skill in the art at the time the invention was made to choose appropriate diameter size the current and voltage pins in order to allow effective current flows and effective testing terminal connections, since it has been held that discovering an optimum value of a result effective variable involves only routine s-kill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). As to claim 5, 638’ discloses the charging current pins and voltage pin have diameters. However, 638’ does not disclose explicitly, wherein: the voltage pin has a diameter of 0.01 or more and 0.2 or less relative to the of a diameter of the pin mounting portion. It would have been obvious to one having ordinary skill in the art at the time the invention was made to choose appropriate diameter size the current and voltage pins allow effective current flows and effective testing terminal connections. since it has been held that discovering an optimum value of a result effective variable involves only routine s-kill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). As to claim 7, 638’ discloses the charging pins and the voltage pins are space apart. . However, 638’ does not disclose explicitly, wherein: the first distance is between 0.01 to 0.5 times a diameter of the pin mounting portion. It would have been obvious to one having ordinary skill in the art at the time the invention was made to choose appropriate diameter size the current and voltage pins in order to allow effective current flows and effective testing terminal connections, since it has been held that discovering an optimum value of a result effective variable involves only routine s-kill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). As to claim 8, 638’ discloses the current pin formed at a periphery of the mounting portion to as to surround the voltage pin. However, 638’ does not disclose explicitly wherein: the current pin is formed in a center of the pin mounting portion, and the voltage pin is formed at a periphery of the pin mounting portion so as to surround the current pin. It would have been obvious to one having ordinary skill in the art at the time the invention was made to rearrange the position of the power supplies such us the batteries or the cells in order to allow effective current flows and avoid any possible short circuits, since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70. As to claim 9, 638’ discloses in figure above, wherein: the current pin has a diameter of 0.5 or more and 0.9 or less times a diameter of the ping mounting portion. It would have been obvious to one having ordinary skill in the art at the time the invention was made to choose appropriate diameter size the current and voltage pins in order to allow effective current flows and effective testing terminal connections. since it has been held that discovering an optimum value of a result effective variable involves only routine s-kill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980 As to claim 10, 638 show in figure above , wherein: the current pin [current pin 20A] and the voltage pin [voltage pin 20B] are spaced apart from each other by a first distance [see figure above, the current pins and the voltage pin are apart]. .As to claim 11, 638’ discloses in figure above, the first distance is between 0.01 to 0.5 times a diameter of the pin mounting portion.
