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 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 12 is rejected under 35 U.S.C. 103 as being unpatentable over Streets et al (US 20170248799). Regarding Claim 12, Streets discloses as set forth above but does not specifically disclose that the eyeglass-type head mounted display according to any one of claims 1, wherein the end piece and the temple are integrated with each other as a single member. However, Streets teaches an eyeglass-type head mounted display (abstract; figs. 1-2), wherein the end piece (fig. 1, 26A-B) and the temple (fig. 1, 14A-B). Further, it has been held that forming in one piece an article which has formerly been formed into two pieces and put together involves only routine skill in the art. Howard v. Detroit Stove Works, 150 US 164 (1893). Therefore, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the eyeglass-type head mounted display of Streets to have the end piece and the temple integrated with each other as a single member, for a purpose to reduce the likelihood of localized heating adjacent the onboard electronic components and heating adjacent the user's face (¶[0014], line 1-15). Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Streets et al (US 20170248799) in a view of Bobuk (US 11340463). Regarding Claim 7, Streets discloses as set forth above but does not specifically disclose that the eyeglass-type head mounted display according to claim 6, wherein the coupling member is a magnet disposed in at least one of the elongated heat transfer member or the image generation device. However, Bobuk teaches a head mounted display device (abstract; figs. 1 and 4); wherein the coupling member is a magnet disposed in at least one of the elongated heat transfer member or the image generation device (fig. 4A, 120, 122, 124; abstract, line 1-12, The hinge includes: (A) a front magnetic component that includes a static magnet, and (B) a rear magnetic component, coupled to the at least one temple section). Therefore, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the eyeglass-type head mounted display of Streets by the head mounted display device of Bobuk for a purpose of providing of a hinge that be quickly disassembled and cleaned as needed ( or replaced in the event that the hinge 114 includes a faulty component) (col. 12, line 5-10). Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Streets et al (US 20170248799) in a view of Tanijiri et al (US 20070177239). Regarding Claim 15, Streets discloses as set forth above and further teaches that the eyeglass-type head mounted display according to any one of claims 1, further comprising: a driver circuit that is fixed to the eyeglass frame and controls the image generation device (fig. 1, 26A-B, 20A-B; ¶[0028], line 1-10, the onboard electronic components 20A and 20B can comprise a power source, power and communication related circuitry, communication devices ( e.g., a camera, a microphone, sensors, etc.), display devices, a computer, a memory, modules, and/or the like). But Streets does not specifically disclose that wherein a coaxial cable, wherein the coaxial cable includes a signal wire that is electrically connected to the driver circuit, and at least one of a shield or a heat transfer wire, the shield surrounds the signal wire, and the at least one of the shield or the heat transfer wire is connected to the elongated heat transfer member. However, Tanijiri teaches image display apparatus (abstract; figs. 1-3); wherein a coaxial cable (fig. 2A, 7; fig. 21, 7), wherein the coaxial cable includes a signal wire that is electrically connected to the driver circuit (fig. 21, 7, 10), and at least one of a shield or a heat transfer wire (fig. 23, 71; ¶[0221], line 1-12, the cable 7 has a plurality of signal conductors 71 bundled inside a shield conductor 72, and has all these covered from around with a cover 73 formed of an insulating material. Thus structured, the cable 7 permits, across the signal conductors 71 thereof, the light source 11 and the display element 14 to be supplied with driving electric power and image signals from the circuit board 9); the shield surrounds the signal wire (fig. 23, 72), and the at least one of the shield or the heat transfer wire is connected to the elongated heat transfer member (¶[0241], line 1-12, the construction for heat rejection from the light source 11; by connecting the heat absorbing member 44 not only to the shield conductor 72….; abstract, line 1-14, heat generated by the light source is efficiently rejected ….. via a shield conductor, led out of a casing, so as to be thereby expelled). Therefore, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the eyeglass-type head mounted display of Streets by the image display apparatus of Tanijiri for a purpose to provide an image display apparatus and a head-mounted display that are designed to avoid degradation of the quality of the image observed by an observer resulting from the heat generated by a light source (¶[0025], line 1-6). Allowable Subject Matter Claim 8 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 an examiner’s statement of reasons for the allowable subject matter: The prior art taken singularly or in combination fails to anticipate or fairly suggest the limitations of the claims, in such a manner that a rejection under 35 U.S.C. 102 or 103 would be proper. In regard to claim 8, the prior art taken either singly or in combination fails to anticipate or fairly suggest a an eyeglass-type head mounted display further comprising wherein the coupling member includes a recess which is formed in one of the elongated heat transfer member and the image generation device, and a protrusion which is formed in the other of the elongated heat transfer member and the image generation device and engages with the recess when the temple is open.
