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 1 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent No. 5,990,870 to Chen et al. in view of U.S. Patent Pub. No. 2012/0146915 A1 to Chen (Chen 2 below). As to claim 1, Chen discloses a combined keypad device comprising: a single handed multipurpose controller (Fig. 2 and 3, column 2, lines 12-15, where the mouse is the single handed multipurpose controller); a housing having a top panel, a bottom surface, a pair of opposing sides, a front side, and a rear panel (Fig. 2, column 2, lines 12-33, where housing (1) has a top panel, bottom surface, pair of opposing sides, front side, and a rear panel as shown); a keypad (Fig. 2, column 2, lines 12-33, where the buttons are the keypad); and a base supporting member (Fig. 2 and 3, column 2, lines 12-33, where the rear of housing (1) is the base supporting member); wherein said base supporting member extending downwardly from said rear panel of said housing (Fig. 2 and 3, column 2, lines 12-33, where the rear of housing (1) extends downwards); wherein said base supporting member is a palm support of a user when operating said single handed multipurpose controller (Fig. 2 and 3, column 2, lines 12-33, where the palm rests on the rear of housing (1)); wherein said top panel having a cavity for selectively attaching said keypad (Fig. 2 and 3, column 2, lines 12-33, where the front of rear housing (1) has space for the keys); wherein said keypad when placed in said cavity accessible by three fingers of a single hand of the user (Fig. 2 and 3, column 2, lines 12-33, where the keys are placed in the space in the front of rear housing (1)); wherein said three fingers are an index finger, a middle finger, and a ring finger (Fig. 2 and 3, column 2, lines 12-33, where there is a button for the index, middle, and ring fingers).
