Office Action

§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-7 and 12 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yu (US 2006/0203204 A1). Regarding claim 1, Yu teaches a first light source (114-G, figure 5) configured to output first light, A first sensor (116-G, figure 5) configured to detect a first measured value corresponding to a temperature of the first light source (paragraph 0085); and A controller (130, figure 1) configured to control an output from the first light source based on the first measured value (figure 2A). Regarding claim 2, Yu teaches the controller is configure to control the output from the first light source by controlling a first drive current (the output light amount of an LED, S220, S230, figure 2A, is directly proportional to the drive current supplied to the LED, therefore control of the current is inherent to this arrangement), which is supplied to the first light source based on the first measured value (S210, figure 2A). Regarding claim 3, Yu teaches the controller is configured to calculate a value that sets the first drive current based on the first measured value, a first coefficient set in advance in correspondence with the first light source, and a first power setting value for the first light source (see figure 3). Regarding claim 4, Yu teaches a second light source (114-R, figure 5) configured to output a second light; and A second sensor (116-RB, figure 5) configured to detect a second measured value corresponding to a temperature of the second light source, Wherein the controller is configured to control an output from the second light source based on the second measured value (S220, S230, figure 2A). Regarding claim 5, Yu teaches the controller is configured to control the output from the first light source by controlling a first drive current, which is supplied to the first light source, based on the first measured value (G-LED, figure 3), and Control the output from the second light source (R-LED, figure 3) by controlling a second driving current, which is supplied to the second light source based on the second measured value (the output light amount of an LED, S220, S230, figure 2A, is directly proportional to the drive current supplied to the LED, therefore control of the current is inherent to this arrangement). Regarding claim 6, Yu teaches the controller is configured to calculate a first power setting value for the first light source and a second power setting value for the second light source , based on a target value expressed in a first color system (paragraph 0054-0055), a first standard value expressed in the first color system and set in advance in correspondence with the first light source, and a second standard value expressed in the first color system and set in advance in correspondence with the second light source (see figure 3), Calculate a value that sets the first drive current based on the first measured value, a first coefficient set in advance in correspondence with the first light source, and the first power setting value (figure 3 and figure 2A), and Calculate a value that sets the second drive current based on the second measured value, a second coefficient set in advance in correspondence with the second light source and the second power setting value (figure 3 and figure 2A). Regarding claim 7, Yu teaches before calculating the first and second power setting values the controller is configured to Correct the first standard value based on the first measured value and a first correction coefficient set in advance in correspondence with the first light source (S220, figure 2A and G-LED, figure 3), and Correct the second standard value based on the second measured value and a second correction coefficient set in advance in correspondence with the second light source (S220, figure 2A and R-LED, figure 3). Regarding claim 12, Yu teaches a light modulator (180, figure 1) configured to modulate light output from the light source apparatus and a projection system (190, figure 1) configured to project the light modulated by the light modulator. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claim(s) 8-11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yu (US 2006/0203204 A1) in view of Watanabe et al. (US 2013/0334965 A1). Regarding claim 8, Yu teaches a third light source (114-B, figure 5) configured to output a third light, and Wherein the controller is configured to control an output from the third light source based on the temperature of the third light source (figure 2A and figure 4). Yu does not teach a third sensor configured to detect a third measured value corresponding to a temperature of the third light source. Watanabe teaches a third sensor configured to detect a third measured value corresponding to a temperature of the third light source (7B, figure 1). It would have been obvious to a person having ordinary skill in the art at the time the invention was made to modify the display system of Yu to dispose each light source independently with its respective temperature sensor as shown in Watanabe in order to more accurately regulate each light source. Regarding claim 9, Yu teaches the controller is configured to control the output from the first light source by controlling a first drive current, which is supplied to the first light source, based on the first measured value (G-LED, figure 3), and Control the output from the second light source (R-LED, figure 3) by controlling a second driving current, which is supplied to the second light source based on the second measured value (the output light amount of an LED, S220, S230, figure 2A, is directly proportional to the drive current supplied to the LED, therefore control of the current is inherent to this arrangement), and Control the second output form the third light source by controlling a third drive current, which is supplied to the third light source, based on the third measured value (B-LED, figure 3). Regarding claim 10, Yu teaches the controller is configured to calculate a first power setting value for the first light source and a second power setting value for the second light source and a third power setting value for the third light source, based on a target value expressed in a first color system (paragraph 0054-0055), a first standard value expressed in the first color system and set in advance in correspondence with the first light source, and a second standard value expressed in the first color system and set in advance in correspondence with the second light source (see figure 3), and a third standard value expressed in the first color system and set in advance in correspondence with the third light source (figure 3), Calculate a value that sets the first drive current based on the first measured value, a first coefficient set in advance in correspondence with the first light source, and the first power setting value (figure 3 and figure 2A), and Calculate a value that sets the second drive current based on the second measured value, a second coefficient set in advance in correspondence with the second light source and the second power setting value (figure 3 and figure 2A), and Calculate a value that sets the third drive current based on the third measured value, a third coefficient set in advance in correspondence with the third light source, and the third power setting value (see figure 3 and figure 2A, see also figure 4 middle graph). Regarding claim 11, Yu teaches before calculating the first and second and third power setting values the controller is configured to Correct the first standard value based on the first measured value and a first correction coefficient set in advance in correspondence with the first light source (S220, figure 2A and G-LED, figure 3), and Correct the second standard value based on the second measured value and a second correction coefficient set in advance in correspondence with the second light source (S220, figure 2A and R-LED, figure 3), and Correct the third standard value based on the third measured value and a third correction coefficient set in advance in correspondence with the third light source (S220, figure 2A and B-LED figure 3).
