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.
Claims 1-6, 10 and 11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hiroteru et al. (WO 2021/132089 A1), hereinafter “Hiroteru”.

Regarding claim 11, Hiroteru discloses wherein the reflecting mirror (2) is a concave mirror (see Fig. 1).
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.
Claims 7 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Hiroteru (WO 2021/132089 A1) in view of Takahiro (WO 2022/130823 A1).
Regarding claim 7, Hiroteru discloses the claimed invention, but does not specify wherein the optical member is a single concave lens. In the same field of endeavor, Takahiro discloses wherein the optical member (30) is a single concave lens (see Figs. 16, 17). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the apparatus of Hiroteru with wherein the optical member is a single concave lens of Takahiro for the purpose of suppressing uneven illuminance (“Background – Art” of translation provided).
Regarding claim 8, Hiroteru and Takahiro teach the image generation apparatus set forth above for claim 7, Takahiro further discloses wherein the incident surface has a plurality of curved convex shapes, and wherein the curved convex shapes face the plurality of light sources, respectively (see Figs. 16, 17). It would have been obvious to one of ordinary skill to provide the image generation apparatus of Hiroteru with the teachings of Takahiro for at least the same reasons as those set forth above with respect to claim 7.
Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Hiroteru (WO 2021/132089 A1) in view of Grief et al. (USPG Pub No. 2020/0310120), hereinafter “Grief”.
Regarding claim 9, Hiroteru discloses an image generation apparatus (HUD) (see Fig. 1, Abstract) configured to generate an image of a head-up display (see Fig. 1, Abstract), the image generation apparatus (HUD) comprising: a plurality of light sources (11) (see Figs. 2, 4, Pg. 3, Paragraph 1); an optical member (12) configured to transmit light emitted from the plurality of light sources (11) (see Fig. 2, Pg. 3, Paragraph 1); and a liquid crystal unit (13) configured to generate a predetermined image by the light emitted from the optical member (see Fig. 2, Pg. 3, Paragraph 1), wherein the optical member (12) includes an incident surface configured to receive the light emitted from the plurality of light sources (11), wherein an emitting surface configured to emit the light received by the incident surface to the liquid crystal unit (13) (see Fig. 2), wherein in a plan view of the liquid crystal unit (13) (see Figs. 2-4), wherein the plurality of light sources (11) are arranged in parallel in a longitudinal direction of the liquid crystal unit (13) (see Figs. 4, 6), and include a first light source (11; 11(3,2)) located at a center in the longitudinal direction and a second light source (11; 11(0,2)) located away from the center (see Fig. 4), and wherein a position of the first light source is different from a position of the second light source in a short direction of the liquid crystal unit (13) (see Figs. 2-4, 6). Hiroteru discloses the claimed invention, but does not specify wherein the optical member is a single Fresnel lens. In the same field of endeavor, Grief discloses wherein the optical member (1060) is a single Fresnel lens (Paragraph 65). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the apparatus of Hiroteru with wherein the optical member is a single Fresnel lens of Grief for the purpose of collimating the optical beams (Paragraph 65).
