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. Claim(s) 1-6, 10 and 14-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kino et al. (20230097485 A1). Regarding claim 1, Kino discloses a comparator (51) (figs. 3, 4, 10B) that compares a signal with a reference signal and outputs a comparison result, the comparator (51) comprising: a differential circuit that outputs a differential voltage between the signal and the reference signal [pars. 0138-141]; and an active load circuit (PT11, PT12) electrically connected to the differential circuit, wherein the differential circuit includes first and second transistors (NT11, NT12) provided on a surface of a substrate a semiconductor substrate [par. 0188], and the first and second transistors have channel regions extending in a direction substantially perpendicular to the surface of the substrate the semiconductor substrate, as can be seen in depicted drawing (figs. 4 and 10B) [pars. 0139-141].

As to claim 14, Kino also disclose, depicted drawing (figs. 3, 4 and 10B) described a configuration corresponding to the light detection element comprising: a pixel portion(11) including a photoelectric conversion element that photoelectrically converts incident light into a pixel signal; and a comparator (51) that compares the pixel signal with a reference signal and outputs a comparison result, the comparator including: a differential circuit that outputs a differential voltage between the pixel signal and the reference signal; and an active load circuit (PT11, PT12) electrically connected to the differential circuit, wherein the differential circuit includes first and second transistors (NT11, NT12) provided on a surface of a substrate, and the first and second transistors have channel regions (see fig. 10B) extending in a direction substantially perpendicular to the surface of the substrate the semiconductor substrate, as can be seen in depicted drawing (figs. 4 and 10B) [pars. 0139-141]. As to claim 15, Kino also disclose depicted drawing (fig. 20) described a configuration corresponding to the, wherein the pixel portion (11) is provided on a first substrate, the comparator (51) is provided on a second substrate different from the first substrate, the first substrate and the second substrate are laminated, and the pixel portion pixel array part 11 and the comparator (51) are electrically connected by a through electrode provided on the first or second substrate or a wiring junction between a wiring of the first substrate and a wiring of the second substrate [pars. 0095, 0210, 0236-0237]. As to claims 16 and 19, Kino also discloses a structure that is use in a comparator system that is implementing limitations such as, wherein the pixel portion pixel array part 11 and the comparator (51) are provided on the same first substrate semiconductor substrates (chips), the comparator (51) is provided above the pixel portion of the first substrate, and the pixel portion and the comparator are electrically connected by a contact plug provided in an interlayer insulating film between the pixel portion and the comparator [pars. 0235-240], as can be seen in depicted drawing (fig. 20) (claim 16); wherein the pixel portion pixel array part 11 and the comparator (51) are provided on the same first substrate, the differential circuit is provided in a same layer as a transistor of the pixel portion, the active load circuit is provided above the pixel portion of the first substrate [pars. 0128-140], and the differential circuit and the active load circuit are electrically connected by a contact plug provided in an interlayer insulating film between the differential circuit and the active load circuit [pars. 0235-240], as can be seen in depicted drawing (fig. 20) (claim 19). For the purposes of clarity, first and second considered arbitrary.

As to claim 20, Kino also discloses depicted drawing (fig. 20) described a configuration corresponding to the electronic device comprising the light detection element [pars. 0255-260]. 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. Claims 7-9 and 11-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kino et al. (20230097485 A1) in view of Yamakawa (20220302192 A1) As to claims 7-9 and 11-13, Kino teaches of the features of claims 7-9 and 11-13, as applied to claim 1, comprising an active load circuit (PT11, PT12) electrically connected to the differential circuit, wherein the differential circuit includes first and second transistors (NT11, NT12) provided on a surface of a substrate a semiconductor substrate [par. 0188], and the first and second transistors have channel regions extending in a direction substantially perpendicular to the surface of the substrate the semiconductor substrate, as can be seen in depicted drawing (figs. 4 and 10B) [pars. 0139-141]. Kino fail to teach the constructional changes in the device/system of claim 1, as that claimed by Applicants claims 7-9 and 11-13, such as, wherein channel length directions of the third and fourth transistors are substantially perpendicular or substantially parallel to a (100) crystal plane of the substrate (claim 7); wherein the substrate is a 45 degree notch substrate, and channel length directions of the third and fourth transistors are substantially perpendicular or substantially parallel to a notch plane on the surface of the substrate (claim 8); wherein the substrate is a 0 degree notch substrate, and channel length directions of the third and fourth transistors are directions inclined at about 45 degrees or about 135 degrees with respect to a notch plane on the surface of the substrate (claim 9); wherein channel length directions of the first and second transistors are substantially perpendicular or substantially parallel to a (110) crystal plane of the substrate (claim 11); wherein the substrate is a 45 degree notch substrate, and channel length directions of the first and second transistors are directions inclined at about 45 degrees or about 135 degrees with respect to a notch plane on the surface of the substrate (claim 12); and wherein the substrate is a 0 degree notch substrate, and channel length directions of the first and second transistors are substantially perpendicular or substantially parallel to a notch plane on the surface of the substrate (claim 13). However, even though, Kino fail to teaches the constructional/structural change differences as that claimed by Applicants claims 7-9 and 11-13, the constructional changes differences are considered obvious design adjustment and variation in view of the field of comparators having transistors, a configuration in which channel length direction of the transistors is substantially parallel to the crystal surface or notch surface, is known, as evidence by Yamakawa (Yamakawa, as can be seen in depicted (figs. 8 and 16). Therefore, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Kino with the constructional/structural change differences as that claimed by Applicants claims 7-9 and 11-13 in the manner set forth in applicant's claims, in order to manufacture an imaging device, and in order to provide an imaging device in which noise can be reduced, since it has been held that the provision of adjustability, where needed, involves only routine skill in the art, In re Stevens, 101 USPQ 284 (CC1954). Additional Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The references listed in the attached form PTO-892 teach of other prior art comparator.
