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 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Carlson in view of Byun (US 20120147065 A1, cited by Applicant)
Regarding claim 19, Carlson teaches the invention set forth in claim 1 above, but is silent regarding a computer processor configured to convert a color value defined based the first virtual primary color point, the second virtual primary color point, and the third virtual primary color point to corresponding outputs for the first primary light-emitting element, the second primary light-emitting element, the third primary light-emitting element, and each of the one or more derivative light-emitting elements.
Byun teaches in [0057], [0061]- [0062] and Fig.11: The data converter 200 performs color coordinate conversion based on the gamma-corrected blue data Bg to generate three-color conversion data and a color gamut determination signal, and inversely gamma-corrects the three-color conversion data.
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date, to use the processor as disclosed in Byun, in the device of Carlson, in order to generate the desired range of colors ([0063]).
Regarding claim 20, Carlson in view of Byun teaches the electronic display of claim 1, wherein the color space chromaticity diagram is an XYZ chromaticity diagram adopted by International Commission on Illumination in 1931 ([0027] in Byun).
