Yu and Kamada are analogous art to the claimed invention because they are concerning with interface for changing color of a device (i.e., same field of endeavor). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention having Yu and Kamada before them to modify the refrigerator of Yu to incorporate the function of presenting control buttons for adjusting RGB values as taught by Kamada. One of ordinary skill in the art would have combined the elements as claimed by known methods as disclosed by Kamada (¶ [0146]-[0158], figs. 5 and 16-18), because the function of presenting control buttons for adjusting RGB values does not depend on the refrigerator. That is the function of presenting control buttons for adjusting RGB values performs the same function independent on which interface it is incorporated onto, and therefore, the result of the combination would have been predictable to one of ordinary skill in the art. The motivation to combine would have been to improve the functionality by providing method to fine tune the color as suggested by Kamada (¶ [0154]). Referring to claim 3, Yu teaches the limitations above. However, Yu does not explicitly teach the method of claim 2, wherein the color control buttons includes a red slider, a green slider and a blue slider, and wherein the input to the color control buttons includes adjusting at least one of the red slider, the green slider and the blue slider. Kamada further teaches the color control buttons includes a red slider, a green slider and a blue slider, and wherein the input to the color control buttons includes adjusting at least one of the red slider, the green slider and the blue slider (¶ [0154], fig. 17, “The amounts of fine tuning for the RGB value set are generated based on the amounts of movement of the knobs on the sliders 512 to 514”).

Kamii teaches to be in a night mode in response to an illuminance value, detected by an illuminance sensor of the home appliance, being below a predetermined illuminance value, wherein the night mode includes reducing the brightness of the lighting device to a preset brightness value (¶ [0330], “The illuminance sensor mode refers to a mode for controlling the dimming ratio based on a result of obtainment by illuminance sensor 28 so as to achieve preset illuminance.” ¶ [0333], “Prior to the illuminance sensor mode, a target illuminance is set. Pressing of "environment registration" button 69 of remote controller 50 by the user causes setting of a target illuminance. Namely, when CPU 22 receives a signal generated as a result of pressing of "environment registration" button 69, then, CPU 22 calculates measured value M2 described above, and obtains calculated measured value M2 as a value indicating the illuminance at that time.” ¶ [0373], “By performing such operations, even when brightness in the surroundings has become extremely low such as when a curtain is closed, a target illuminance can appropriately be achieved.”) Yu, Hong, Lotus, and Kamii are analogous art to the claimed invention because they are concerning with interface for controlling lighting device (i.e., same field of endeavor). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention having Yu in view of Hong and Lotus and Kamii before them to modify the refrigerator of Yu in view of Hong and Lotus to incorporate the function of adjusting brightness according illuminance value as taught by Kamii. One of ordinary skill in the art would have combined the elements as claimed by known methods as disclosed by Kamii (¶ [0329]-[0377]), because the function of adjusting brightness according illuminance value does not depend on the refrigerator. That is the function of adjusting brightness according illuminance value performs the same function independent on which interface it is incorporated onto, and therefore, the result of the combination would have been predictable to one of ordinary skill in the art. The motivation to combine would have been to improve user experience by automatically maintaining desired illuminance value regardless of the lighting condition as suggested by Kamii (¶ [0373]). Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Yu in view of Hong as applied to claim 7 above, and further in view of Xodo, (“Adding favorite colors”) (hereinafter Xodo). Referring to claim 12, Yu teaches the method of claim 7. However, Yu does not explicitly teach displaying, on the user interface, an add color button for adding a new color to the home appliance; displaying, on the user interface, a plurality of color selection buttons, the plurality of color selection buttons including a red button, a green button and a blue button; and changing a color displayed on the selected panel in response to a selection of at least one of the red button, the green button and the blue button. Hong further teaches displaying, on the user interface, a plurality of color selection buttons, the plurality of color selection buttons including a red button, a green button and a blue button (¶ [0105], figs. 7 and 8, “a red group graphic object G43 corresponding to the red group…a blue group graphic object G45 corresponding to the blue group, and a green group graphic object G46 corresponding to the green group.”); and changing a color displayed on the selected panel in response to a selection of at least one of the red button, the green button and the blue button (¶ [0109], figs. 7-9, “in response to selecting the yellow group graphic object G41, a color graphic object G50Y representing a plurality of colors included in the yellow group may be displayed on the first region R1 of the color recommendation user interface U2.” ¶ [0112], figs. 7-9, “one of the plurality of colors may be selected through one G52Y of the plurality of color graphic objects. In response to selecting a color, the selected color may be applied to the selected door graphic object G31 among the plurality of door graphic objects G31, G32, G33, and G34 displayed on the second region R2.”) Yu in view of Hong teach the user interface for changing color displayed on the home appliance. However, Yu in view of Hong do not explicitly teach the user interface includes an add color button for adding a new color... Xodo teaches displaying, on the user interface, an add color button for adding a new color... (Pg. 1-2, the methods 1 and 2 teach adding a new color to the favorite list). Yu, Hong, and Xodo are analogous art to the claimed invention because they are concerning with interface for controlling display of color (i.e., same field of endeavor). It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention having Yu in view of Hong and Xodo before them to modify the refrigerator of Yu in view of Hong to incorporate the function of an adding new color button as taught by Xodo. One of ordinary skill in the art would have combined the elements as claimed by known methods as disclosed by Xodo (Pg. 1-3), because the function of an adding new color button does not depend on the refrigerator. That is the function of an adding new color button performs the same function independent on which interface it is incorporated onto, and therefore, the result of the combination would have been predictable to one of ordinary skill in the art. The motivation to combine would have been to improve user experience by allowing user quick access to favorite color(s). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure. US 20140091731 (Fushimi) – discloses a method of controlling lighting system via an user interface. US 20090231248 (Dorff) – discloses graphical user interface for configuring color of a device cover.
