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 .
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 09/13/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Objection/s to the Specification
The title of the invention, “DISPLAY DEVICE,” is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed.
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 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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-6 and 8 are rejected under 35 U.S.C. 102(a)(1)/(a)(2) as being anticipated by Shimoyama (US 20190363512 A1).
Regarding claim 1, Shimoyama teaches a display device (Fig. 1-7) comprising: a light source (125); an optical engine (121, 123, 30, and/or 42) configured to generate image light to be displayed on a display surface on the basis of light from the light source (125); a power supply board (12 and/or 16) configured to drive the light source (125) and the optical engine (121, 123, 30, and/or 42); and a case (11) configured to accommodate a device component which comprises at least one of the optical engine (121, 123, 30, and/or 42) and the power supply board (12 and/or 16), wherein the case (11) has a wall (11a/b/c) which include a heat radiating part that is thermally connected to a heat generating component (14/18) included in the device component, to allow heat of the heat generating component (14/18) to be released outside of the case (11), and wherein the heat generating component (14/18) is mounted on a first surface (top surface) of a board (12 and/or 16) included in the device component.
Regarding claim 2, Shimoyama further teaches the device component includes a plurality of the heat generating components (14/18) that are thermally connected to an inner surface of the wall (11c) facing the first surface (top surface).
Regarding claim 3, Shimoyama further teaches a second surface (bottom surface) of the board (12 and/or 16), which faces a side opposite to the first surface (top surface), is thermally connected to a different wall (11a) of the case (11), and the different wall (11a) faces the second surface (bottom surface).
Regarding claim 4, Shimoyama further teaches a thermal connection component (11d/19) configured to fill a space between the heat generating component (14/18) and the inner surface of the wall (11c) so as to thermally connect the heat generating component (14/18) and the wall (11c) to each other.
Regarding claim 5, Shimoyama further teaches a plurality of heat radiator fins (11f) on an outer surface of the wall (11a/c; Fig. 7).
Regarding claim 6, Shimoyama further teaches the heat radiator fins (1f) are disposed on the outer surface of the wall (11a/b/c) facing at least the first surface (top surface) of the board (12 and/or 16; Fig. 7).
Regarding claim 8, Shimoyama further teaches a projection lens (60) configured to magnify the image light.
Claim Rejections - AIA 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 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 of this title, 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 7 is rejected under 35 U.S.C. 103 as being unpatentable over Shimoyama in view of Fujiwara (US 20030007327 A1).
Regarding claim 7, Shimoyama does not teach a fan.
Fujiwara further teaches a fan (22) configured to flow air outside the case (25) for cooling the case (25), wherein the fan (22) is configured to cause air to flow in a direction in which the heat radiator fins (50) extend along the outer surface of the wall (25).
It would have been obvious to a person of ordinary skills in the art at the time of the invention to combine Shimoyama with Fujiwara; because it improves heat dissipation.
Conclusion
The prior art references cited in PTO-892 are made of record and considered pertinent to applicant's disclosure.
Patent documents, US 20200159098 A1, US 20200159097 A1, US 20200096852 A1, US 20190179217 A1, US 20090213560 A1, US 20070296929 A1, and US 20060077354 A1, disclose various cooling arrangements for electronical components inside projectors.
