Paragraphs [56-58]. 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 9,11-13, 18-21 are rejected under 35 U.S.C. 103 as being unpatentable over by Twaddell (US Pub. No: 2021/0068238) in view of Ho et al (US Pub. No: 2022/0342373). With respect to claim 9, Twadell discloses all limitations recited in claim 2, except for wherein the present color is defined by a present x-chromaticity coordinate and a present y-chromaticity coordinate. Ho et al disclose a color is defined by a present x-chromaticity coordinate and a present y-chromaticity coordinate. Paragraph [149]. It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the features of Twadell into the remote control device of Twadell to select color in x-chromaticity coordinate and y-chromaticity coordinate to vary color of light sourcea. With respect to claim 11, Twaddell discloses the actuators on the touch sensitive surface except for icons for indicating positions of the actuators on the touch sensitive surface. Ho et al disclose icons for indicating positions of the actuators on the touch sensitive surface. Paragraphs [22,86,122]. It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the features of Ho et al into the remote control device of Twadell to provide ions for controlling light level and the user may select the input event 402a for triggering the scene by selecting a button on the icon 402b. With respect to claim 12, Twaddell as modified claim 11 above, discloses further comprising: one or more light sources for illuminating respective ones of the icons on the touch sensitive surface. Paragraphs [123,125]. With respect to claim 13, Twaddell as modified claim 12 above, wherein, when each of the icons is not illuminated, the respective icons is configured to disappear. With respect to claim 18, Twaddell discloses all limitations recite in claim 17 above, except for wherein, when in the color-temperature-adjustment mode, the control circuit is configured to: generate the second control data for adjusting the present color temperature of each of the one or more lighting loads across a range from a warm-white color temperature to a cool-white color temperature; illuminate a segment of the light bar to indicate the present color temperature of the one or more lighting loads; and adjust a position of the segment around a circumference of the light bar based on the present color temperature within the range from the warm-white color temperature to the cool-white color temperature. Ho et al disclose as shown in paragraph [131] for controlling lighting loads to cooler colors or temperature values and controlling lighting loads to warmer colors or temperature values. It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the features of Ho et al into the remote control device of Twadell to control cooler or warm colors to improve a life time of the light sources. With respect to claim 19, Twaddell as modified claim 18 above, discloses wherein, when in the color-temperature-adjustment mode, the control circuit is configured to: illuminate the light bar to a gradient of colors starting at a point on the light bar and sending at the point on the light bar, the gradient of colors starting at a first color and ending at a second color to represent the range of color temperatures between the warm-white color temperature and the cool-white color temperature; and illuminate the segment of the light bar a third color overtop of the gradient of colors to indicate the present color temperature of the one or more lighting loads. Paragraph [131] of Ho et al. With respect to claim 20, Twaddell as modified claim 20 above, disclose wherein the first color comprises a red color, the second color comprises a blue color, and the third color comprises a white color. Paragraphs [23, 28] of Ho et al. With respect to claim 21, Twaddell as modified claim 19 above, disclose wherein, when in the intensity-adjustment mode, the control circuit is configured to illuminate a portion of the light bar that starts at the point on the light bar extends for a length around the circumference of the light bar in a clockwise direction, where the length of the illuminated portion indicates the present intensity level of the one or more lighting loads. Paragraph [24] of Twaddell disclose an operational modes may include a lighting control mode for controlling one or more lighting loads (e.g., which in turn may include a color control mode and an intensity control mode). Claims 14-16 are rejected under 35 U.S.C. 103 as being unpatentable over by Twaddell (US Pub. No: 2021/0068238) in view of Moorthy (US Pub. No: 2022/0174801). With respect to claim 14, Twaddel disclose all limitations recite in claim 10 above, except for wherein the actuators of the touch sensitive surface comprise an undo actuator, and the control circuit is configured to generate third control data for causing the lighting load to revert to a previous state in response to an actuation of the undo actuator. Moorthy disclose after turning the lighting load on in response to a first actuation (e.g., a touch actuation) of the actuation member 210 (e.g., the touch sensitive surface), the control device may receive (e.g., consistently receive) a second actuation (e.g., a touch actuation) that undoes or adjusts the control initiated by the first actuation (e.g., adjusts the intensity level). Paragraphs [73, 147]. It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the features of Mooerthy into the remote-control device of Twadell to perform actuator and undo actuator to avoid unintentional operations that are caused by accidental touch actuations received via the touch sensitive surface. With respect to claim 15, Twaddell as modified claim 14 above, disclose further comprising: a communication configured to transmit messages, the control circuit communicatively coupled to the control circuit; wherein the control circuit is configured to transmit a third command for causing the lighting load to revert to the previous state in response to the generated third control data. Paragraphs [60,62,98,100]. With respect to claim 16, Twaddell disclose further comprising: a memory configured to store at least one of a stored intensity level or a stored color temperature; wherein, in response to the generated third control data, the control circuit is configured to transmit a third command for adjusting the at least one of the intensity level or the color temperature of the lighting load to at least one of the stored intensity level or a stored color temperature, respectively.
