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
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.
Claims 1-7 are rejected under 35 U.S.C. 102 (a) (1) as being anticipated by Miyazaki et al [JP 2016133609 – IDS].
Miyazaki discloses and illustrates in at least Figures 2 and 4 a projection image display device with a cooling device comprising:
a container (a dust-proof case 10) is sealed and accommodates a first heating element (display devices 7R/7G/7B);
a first radiator (heat exchanging unit comprising 5B radiating portion) disposed outside the container;
a first air blower (cooling fan 17) that blows wind to the first radiator; and
a heat dissipator (heat sinks 12R/12G/12B) that is disposed outside the container to receive the wind from the first air blower and dissipates heat of the first element, wherein the heat dissipator is connected the first heat element (7R/7G/7B);
a prism 8 that is accommodated in the container to separate incident light into a plurality of colors of light and combine the plurality of colors of light.
Miyazaki discloses in [0009]: ‘the device suppresses dust and dust from adhering to the optical light processing unit 3 into which light from the light source is incident, and suppress the respective members of the light processing unit from being overheated. Miyazaki discloses in the abstract the invention directed to a projector that suppresses dust/dirt being adhered to an optical processing unit and suppress each member of the optical processing unit from being placed in to an overheated state.
Per multiple (first/second/third/fourth) flow paths with respect the relationships to the generated heat and cooling air, Miyazaki discloses and illustrates in the figures multiple (first/second/third) heating elements (display devices 7R/7G/7B), wherein heat dissipators (heat sinks 12R/12G/12B) that are disposed outside the container to receive the wind from the (first) air blower 17 and dissipate heat of the elements. Here, Miyazaki discloses and illustrates multiple flow paths with respect to the direct/indirect flowing generated heat/cooling air from/to the heating elements, the radiators, the heat dissipators.
Per a second air blower and a second radiator from claims 4-5, Miyazaki discloses [0014] and illustrates in the figures a (second) air blower 16 and the heat exchanging unit 5 comprising a (second) radiating portion in the container (dust-proof case 10).

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.
Claim 8-9 are rejected under 35 U.S.C. 103 as being unpatentable over Miyazaki et al [JP 2016133609 – IDS] above in view of Nakahito et al [JP2002352622, IDS] and CN 214375779 U (892 ref).
The limitation not explicitly disclosed by Miyazaki is a light shielding plate.
The use of a light shielding means to block out undesired/unnecessary light into devices’ components that would minimizing/prevent deteriorating quality and/or malfunction to the components.
Nakahito discloses a projection image display device with a cooling device comprising the use of a light shielding plate for advantages such as preventing user’s eyes from being damaged without deteriorating the cooling efficiency of the fan, preventing failures/malfunction to devices’ components due an increase in temperature. CN ‘779 discloses a projection mage display device with a cooling device comprising the use of light shielding plate 51 for effective shielding light at the display projecting portion so as the contrast of the display is improved.
Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to incorporate the use of a light shielding plate for advantages such as preventing user’s eyes from being damaged without deteriorating the cooling efficiency of the fan, preventing failures/malfunction to devices’ components due an increase in temperature, the contrast of the display is improved.
Per the prism and the image display device comprising DMD from claims 8-9, Miyazaki discloses [0013] a projector 1 comprising the prism 8 and the (second) heating element (display devices 7R/7B/7G), wherein the display devices are such as DMD.
Allowable Subject Matter
Claim 10 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: The prior art of record neither anticipates nor render obviousness a projection image display device comprising: a cooling device a container that is sealed and accommodates a first heating element; a first radiator disposed outside the container; a first air blower that blows wind to the first radiator; and a heat dissipator that is disposed outside the container to receive the wind from the first air blower and dissipates heat of the first heating element; the cooling device further comprising a heat receiver that is disposed in the container and receives heat of a second heating element disposed in the container; a first flow path that is connected to the first radiator and the heat receiver, wherein a refrigerant cooled by the first radiator flows through the first flow path; and a second flow path that is connected to the heat receiver and the first radiator, wherein the refrigerant raised in temperature by the heat receiver flows through the second flow; prism that is accommodated in the container to separate incident light into a plurality of colors of light and combine the plurality of colors of light, wherein the second heating element includes an image display facing one surface of the prism, and the first heating element includes a light shielding plate that shields light reflected from the image display, the light shielding plate includes: a photo detector that receives light reflected from the image display, and a heat-conducting plate connected to the photo detector, and the heat-conducting plate is connected to the heat dissipator via the container.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
