[0080]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the expansion base of Lin to incorporate a first magnetic member, wherein the first magnetic member is arranged at the first fixing portion; and the first magnetic member is configured to magnetically cooperate with a second magnetic member on the at least one expansion device to fix the at least one expansion device to the first fixing portion as suggested by Lee because such modification helps to magnetically attract and retain the expansion device to the fixing portion of the expansion base. Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lin in view of Sa (US 20100102777; “Sa’777” hereinafter). Regarding claim 9, Lin discloses wherein the front plate is connected to the bottom plate at an acute angle (annotated fig. 6 above); the placement portion comprises a rear supporting plate connected to the top plate (annotated fig. 6 above); a bottom bearing plate connected to the rear supporting plate (annotated fig. 4 below). Lin does not explicitly disclose the rear plate is also connected to the bottom plate at an acute angle; a front supporting plate connected to the bottom bearing plate, and a limiting plate; the rear supporting plate and the bottom bearing plate are connected at an obtuse angle; the limiting plate is connected between the front supporting plate and the front plate; the front supporting plate is connected to the bottom bearing plate at an obtuse angle; and the front supporting plate is connected to the limiting plate at an obtuse angle; and the bottom plate and the bottom bearing plate are parallel to each other. Sa’777 teaches an expansion base comprising a fixing portion that further comprises a bottom bearing plate (“bottom bearing plate” annotated fig. 1D) connected to the rear supporting plate (“rear bearing plate” annotated fig. 1D), a front supporting plate (“front bearing plate” annotated fig. 1D) connected to the bottom bearing plate (annotated fig. 1D), and a limiting plate (“limiting plate” annotated fig. 1D); the rear supporting plate and the bottom bearing plate are connected at an obtuse angle (annotated fig. 1D); the limiting plate is connected between the front supporting plate and the front plate (annotated fig. 1D); the front supporting plate is connected to the bottom bearing plate at an obtuse angle (annotated fig. 1D) and the front supporting plate is connected to the limiting plate at an obtuse angle (annotated fig. 1D). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the expansion base of Lin to incorporate a front supporting plate connected to the bottom bearing plate, and a limiting plate; the rear supporting plate and the bottom bearing plate are connected at an obtuse angle; the limiting plate is connected between the front supporting plate and the front plate; the front supporting plate is connected to the bottom bearing plate at an obtuse angle; and the front supporting plate is connected to the limiting plate at an obtuse angle as taught by Sa’777, because such modification provides supports to the expansion device or the mobile device that is docked or plugged onto or into the fixing portion. However, Lin in view of Sa’777 does not explicitly disclose the rear plate is also connected to the bottom plate at an acute angle; and the bottom plate and the bottom bearing plate are parallel to each other. It would have been obvious to one of ordinary skill in the art before the effective date of the claimed invention to modify the shape of the rear plate or rearrange the rear plate with respect to bottom plate and bottom plate, and modify the shape of the bottom bearing plate or rearrange the bottom bearing plate with respect to bottom plate such that the rear plate is also connected to the bottom plate at an acute angle, and the bottom plate and the bottom bearing plate are parallel to each other, since changing the shape of the rear plate and bottom bearing plate or rearranging the rear plate and bottom bearing appears to be an obvious matter of engineering design choice and thus, while being a difference, does not serve in any way to patentably distinguish the claimed invention from the applied prior art. In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966). In re Japikse, 86 USPQ 70 (CCPA 1950) PNG media_image2.png 327 608 media_image2.png Greyscale PNG media_image3.png 804 755 media_image3.png Greyscale Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lin in view of Hirosawa (US 20160126757; “Hirosawa” hereinafter). Regarding claim 10, Lin discloses the expansion base as claimed in claim 8. Lin does not explicitly disclose the expansion base according to claim 8, further comprising a built-in battery, wherein the built-in battery is arranged inside the first housing and is electrically connected to the first circuit board. Hirosawa teaches an expansion base comprising a built-in battery (340), wherein the built-in battery is arranged inside a first housing (12) and is electrically connected to a circuit board (342) (fig. 2). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the expansion base of Lin to incorporate a built-in battery, wherein the built-in battery is arranged inside the first housing and is electrically connected to the first circuit board as suggested by Hirosawa because with such modification the built-in battery provides power to the mobile device whenever necessary and also the expansion base works as a standalone device to supply power to the mobile device or the expansion base when there is no external power source or AC power source. Claim(s) 18-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lin in view of Carnevali (US 20170371374 ; “Carnevali” hereinafter). Regarding claim 18, Lin discloses an expansion base, comprising: a first housing (101, 102), wherein the first housing comprises a first fixing portion (docking slot cover by the elastic gate 103 where the battery 301 is inserted, par. [0019], [0020], fig. fig. 8) and a placement portion (202); the first fixing portion is configured to detachably assemble at least one expansion device (301), and the placement portion is configured to slantways or vertically place a mobile device (501)( figs 4, 6-8); a first circuit board (701) arranged inside the first housing (fig. 8); and a first connection interface (interface connected at the end of 702 that electrically connects to the contact area 302 of the battery 301), wherein the first connection interface is electrically connected to the first circuit board (“The elastic joint 702 is capable of touching the rechargeable battery 301 closely due to its curve and elasticity, so that the rechargeable battery 301 is well connected with the recharge PCB 701 via the elastic joint 702”, par. [0022]); and the first connection interface is arranged at the first fixing portion (fig. 7-8), and is configured to be coupled with a second connection interface (302) on the at least one expansion device (301) when the at least one expansion device is assembled on the first fixing portion (figs 7-8, par. [0022]), so that the expansion base takes power from the at least one expansion device, supplies power to the at least one expansion device (301) (“When the rechargeable battery is inserted for recharging”, par. [0007]), and/or communicates with the at least one expansion device to transmit data. Lin does not explicitly disclose an expansion supporting device, comprising a second expansion base, wherein the first expansion base and the second expansion base are arranged side by side to jointly support the same mobile device. Carnevali teaches an expansion supporting device, comprising a first expansion base (258), a second expansion base (252), wherein the first expansion base and the second expansion base are arranged side by side to jointly support a mobile device (101) (figs 2A-2B, 3B). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the expansion base of Lin to incorporate a second expansion base such that wherein the first expansion base and the second expansion base are arranged side by side to jointly support the same mobile device as taught by Carnevali because such modification provides supports to the mobile device when docked and helps in alignment of the mobile device with the contact or connecting interface of the first expansion base. Regarding claim 19, Lin in view of Carnevali (relied on Carnevali) discloses wherein the first expansion base (258) and the second expansion base (252) are connected into a whole through a connection structure (252 and 258 are connected via arm 254); and when the first expansion base and the second expansion base are connected into a whole, the placement portion (275) of the first expansion base and the placement portion (256) of the second expansion base are aligned and connected (guide portions 256 and 176 are connected via base 252, arm 254, figs 2A-2B). Lin in view of Carnevali does not explicitly disclose the connection structure comprising a buckle. It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to substitute connection structure of Carnevali with a buckle, since it has been held that the simple substitution of one known element for another to obtain predictable results is obvious (KSR). Regarding claim 20, Lin in view of Carnevali discloses wherein the second expansion base (252, Carnevali) is the same with the first expansion base (258, Carnevali); the first expansion base is integrally formed with the second expansion base (figs 2A-2B, Carnevali); and the at least one expansion device comprises at least one of a heat dissipation device, a docking station, a storage device, a power bank (301 is a chargeable battery), a lighting module, and a heat dissipation and lighting module.
