Claim Rejections - 35 USC § 103 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 2-10, 12-15, and 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over Fergason (US 2005/0017152 A1). In regard to claim 2, Fergason discloses the limitations as applied to claim 1 above, and each of the plurality of actuators 18 is spaced apart from another one of the plurality of actuators 18 by a distance (see e.g. Figures 1b-2b). Fergason fails to explicitly disclose wherein the plurality of actuators is arranged in an array of rows and columns. However, 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 device of Fergason with wherein the plurality of actuators is arranged in an array of rows and columns, since it has been held that rearranging parts of an invention involves only routine skill in the art (see e.g. MPEP 2144.04, In re Kuhle, 526 F.2d 553, 188 USPQ 7 (CCPA 1975) ). 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 device of Fergason with wherein the plurality of actuators is arranged in an array of rows and columns. Providing a desired configuration of the actuators would allow the device to be customized for particular uses or users. In regard to claim 3, Fergason discloses the limitations as applied to claim 2 above, but fails to disclose wherein the array of rows and columns includes two rows and three columns. However, 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 device of Fergason with wherein the array of rows and columns includes two rows and three columns, since it has been held that rearranging parts of an invention involves only routine skill in the art (see e.g. MPEP 2144.04, In re Kuhle, 526 F.2d 553, 188 USPQ 7 (CCPA 1975) ). 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 device of Fergason with wherein the array of rows and columns includes two rows and three columns. Providing a desired configuration of the actuators would allow the device to be customized for particular uses or users. In regard to claim 4, Fergason discloses the limitations as applied to claim 2 above, and wherein the body (i.e. including at least element 10 in Figure 1b) includes a top end, a bottom end opposite to the top end, a first side, and a second side opposite to the first side, and the plurality of actuators 18 are closer to the first side than to the second side, and are closer to the bottom end than to the top end (see e.g. Figures 1a, 2a). In regard to claim 5, Fergason discloses the limitations as applied to claim 4 above, but fails to disclose wherein the control panel includes a screen that is closer to the second side than to the first side, and closer to the bottom end than to the top end. However, 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 device of Fergason with wherein the control panel includes a screen that is closer to the second side than to the first side, and closer to the bottom end than to the top end, since it has been held that rearranging parts of an invention involves only routine skill in the art (see e.g. MPEP 2144.04, In re Kuhle, 526 F.2d 553, 188 USPQ 7 (CCPA 1975) ). 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 device of Fergason with wherein the control panel includes a screen that is closer to the second side than to the first side, and closer to the bottom end than to the top end.

Fergason fails to disclose a width of at least 10.0mm and a height of 9.0 mm. However, one of ordinary skill in the art before the effective filing date of the claimed invention would recognize using a width of at least 10.0mm and a height of 9.0 mm, since it has been held that where the general condition of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art (see e.g. MPEP 2144.05). 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 device of Fergason with a width of at least 10.0mm and a height of 9.0 mm. Providing an optimized height of the actuators would allow operation of the device under the specific operating conditions (i.e. being able to have sufficient contact with a user’s hand and/or protective gear on user’s hand). In regard to claim 7, Fergason discloses the limitations as applied to claim 6 above, but fails to disclose wherein each of the plurality of actuators has a width of at least 12.0 mm and a height of at least 10.0 mm. However, one of ordinary skill in the art before the effective filing date of the claimed invention would recognize using wherein each of the plurality of actuators has a width of at least 12.0 mm and a height of at least 10.0 mm, since it has been held that where the general condition of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art (see e.g. MPEP 2144.05). 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 device of Fergason with wherein each of the plurality of actuators has a width of at least 12.0 mm and a height of at least 10.0 mm. Providing an optimized height of the actuators would allow operation of the device under the specific operating conditions (i.e. being able to have sufficient contact with a user’s hand and/or protective gear on user’s hand). In regard to claim 8, Fergason discloses the limitations as applied to claim 6 above, but fails to disclose wherein each of the plurality of actuators is spaced apart from another one of the plurality of actuators in a horizontal direction by a distance greater than 3.0 mm, and is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 3.0 mm. However, one of ordinary skill in the art before the effective filing date of the claimed invention would recognize using wherein each of the plurality of actuators is spaced apart from another one of the plurality of actuators in a horizontal direction by a distance greater than 3.0 mm, and is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 3.0 mm, since it has been held that where the general condition of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art (see e.g. MPEP 2144.05). 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 device of Fergason with wherein each of the plurality of actuators is spaced apart from another one of the plurality of actuators in a horizontal direction by a distance greater than 3.0 mm, and is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 3.0 mm. Providing a configuration of actuators that has a particular spacing would allow operation of the device under the specific operating conditions (i.e. being able to have sufficient contact with a user’s hand and/or protective gear on user’s hand). In regard to claim 9, Fergason discloses the limitations as applied to claim 8 above, but fails to disclose wherein each of the plurality of actuators is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 4.0 mm, and is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 4.0 mm. However, one of ordinary skill in the art before the effective filing date of the claimed invention would recognize using wherein each of the plurality of actuators is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 4.0 mm, and is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 4.0 mm, since it has been held that where the general condition of a claim are disclosed in the prior art, discovering the optimum or working ranges involves only routine skill in the art (see e.g. MPEP 2144.05). 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 device of Fergason with wherein each of the plurality of actuators is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 4.0 mm, and is spaced apart from another one of the plurality of actuators in the horizontal direction by a distance greater than 4.0 mm. Providing a configuration of actuators that has a particular spacing would allow operation of the device under the specific operating conditions (i.e. being able to have sufficient contact with a user’s hand and/or protective gear on user’s hand). In regard to claim 10, Fergason discloses the limitations as applied to claim 6 above, but fails to disclose wherein each of the plurality of actuators has a substantially rectangular shape. However, it would have been obvious to one of ordinary skill in the art before the effective filing date to select a configuration in which wherein each of the plurality of actuators has a substantially rectangular shape, since it has been held that a mere change in shape of an element is generally recognized as being with in the level of ordinary skill in the art when the change in shape is not significant to the function of the combination (see e.g. MPEP 2144.04, In re Dailey 149 USPQ 47 (CCPA 1966). 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 device of Fergason with wherein each of the plurality of actuators has a substantially rectangular shape. Selecting a particular shape of the actuators would be considered a design choice that would not change the operability of the device and is considered a matter of design choice.
