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 § 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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or non-obviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.

As of claim 34, the closest prior art LIN (US 2017/0302894 A1) teaches a projection apparatus 1000 which includes a light source 100, a color light generating assembly 200, a light valve 300 and a projection lens 400. The light source 100 is configured to generate an illumination beam L. The illumination beam L is transmitted along a transmission path and irradiated onto the color light generating assembly 200. The color light generating assembly 200 is configured to sequentially convert the incident illumination beam L into a plurality of sub-illumination beams L1, L2, L3 and L4. The sub-illumination beams L1, L2, L3 and L4 exhibit different colors, such as red, green, blue and white lights respectively. The sub-illumination beams L1, L2, L3 and L4 are reflected by a mirror M of the projection apparatus 1000 and then incident onto the light valve 300 at a proper angle. The light valve 300 is configured to convert the sub-illumination beams L1, L2, L3 and L4 into a plurality of sub-image beams L1′, L2′, L3′ and L4′, respectively. The sub-image beams L1′, L2′, L3′ and L4′ are projected onto a screen (not shown) by the projection lens 400 so as to superimpose the sub-image beams L1′, L2′, L3′ and L4′ to form a color image. In the present embodiment, the light valve 300 may be a reflective digital micro-mirror device (DMD) or a liquid crystal on silicon (LCoS) panel, but the present invention is not limited thereto. In another embodiment, the light valve 300 may be a transmissive liquid crystal display (LCD) panel, working in conjunction with necessary adjustments on the related optical components and positions thereof. In another embodiment, the mirror M in FIG. 1 may be omitted or replaced by other optical components (e.g., a total internal reflection prism) with required adjustments on the related optical components and positions thereof. The structure of the color light generating assembly 200 of the present invention will be described in detail in the following. FIG. 2 is a schematic view of a color light generating assembly in accordance with an embodiment of the present invention. FIG. 3 is a schematic view of a reciprocating module of the color light generating assembly of FIG. 2 in accordance with an embodiment of the present invention. Please refer to FIGS. 2 and 3. As shown, the color light generating assembly 200 of the present embodiment includes a color wheel module 210 and a reciprocating module 220. The reciprocating module 220 is connected to the color wheel module 210 and configured to drive the color wheel module 210 to reciprocate.

The first driving device 214 is engaged with the center of the color wheel 212 and configured to drive the color wheel 212 to rotate about the center. In the present embodiment, the first driving device 214 is a motor. The rotating shaft of the motor is engaged with the center of the color wheel 212 and the motor is configured to drive the color wheel 212 to rotate about the center. The color wheel 212 may include four filters 212R, 212G, 212B and 212W. Specifically, the filter 212R is a red filter; the filter 212G is a green filter; the filter 212B is a blue filter; and the filter 212W is a white filter or a transparent sheet. Therefore, the aforementioned sub-illumination beams L1, L2, L3 and L4 of different colors are sequentially generated after the optical axis of the illumination beam L passes through the filters 212R, 212G, 212B and 212W along a predetermined direction (e.g., along a direction parallel to the Z-axis in FIG. 1), respectively. LIN does not anticipate or render obvious, alone or in combination, a thermal interface layer, wherein the driving device has a back side, the back side faces the second end portion of the support, and the thermal interface layer is disposed between the back side and the support and in contact with the back side and the support.
