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 9 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over (CN-111416077-A) hereinafter referred to as ‘Fukinuki’ in view of (US-20210273474-A1) hereinafter referred to as ‘Seibert’ Regarding Claim 9, Fukinuki does not teach the battery pack according to claim 7, further comprising a button disposed on the first housing and a light source disposed within the first housing; wherein the button is made of a light-transmitting material and is disposed adjacent to the light source; light from the light source is emitted from the button out of the first housing.

Seibert teaches that the light would indicate to the user information about the battery device (Seibert, “The buttons may thus be designed, for example, directly as light-emitting elements, in order to indicate directly to the user which charging mode he/she has selected”, see [0020]). Fukinuki and Seibert and analogous as they are both of the same field of battery devices. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the battery has taught in Fukinuki with the LED button as taught in Seibert in order to convey to the user information which is relevant about the battery system. Regarding Claim 18, Fukinuki does not teach the battery pack according to claim 13, further comprising a button disposed on the first housing and a light source disposed within the first housing; wherein the button is made of a light-transmitting material and is disposed adjacent to the light source; light from the light source is emitted from the button out of the first housing. Seibert teaches a button disposed on the first housing and a light source disposed within the first housing (Seibert, “Such an operating unit may preferably be designed as one or multiple push buttons that are located directly on the charging device”, see [0020]); wherein the button is made of a light-transmitting material and is disposed adjacent to the light source (Seibert, “Such an indicator may be designed, for example, as an LED indicator, as a touch-sensitive or non-touch-sensitive display (LCD, TFT, OLED, E-paper, etc.)”, see [0020]); light from the light source is emitted from the button out of the first housing (Seibert, “The buttons may thus be designed, for example, directly as light-emitting elements, in order to indicate directly to the user which charging mode he/she has selected”, see [0020]). Seibert teaches that the light would indicate to the user information about the battery device (Seibert, “The buttons may thus be designed, for example, directly as light-emitting elements, in order to indicate directly to the user which charging mode he/she has selected”, see [0020]). Fukinuki and Seibert and analogous as they are both of the same field of battery devices. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the battery has taught in Fukinuki with the LED button as taught in Seibert in order to convey to the user information which is relevant about the battery system.
