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(s) 5 – 7 and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yasutake US Publication 2022/0236624 in view of Su US Publication 2014/0078467. Regarding claim 5 Yasutake further discloses of applicant’s wherein the light blocking member includes a first opening through which external light passes (paragraph 0040, Fig. 3 and 4, light-shielding unit 901 shields the reflected light of the infrared illumination 12a so that the reflected light does not arrive at the lens barrel 902 where (paragraph 0019) imaging unit 9 includes a lens barrel 902 (imaging unit) that includes an image sensor and a lens group (neither of which is illustrated) such that the light-shielding unit blocking member 901 includes a first opening through which external light passes to the lens barrel 902 image sensor); Yasutake discloses an image sensor in a lens that receives light from an infrared illumination in an opening in a light-shielding unit but does not expressively disclose a first opening through which external light passes and a second opening through which light emitted from the lighting unit passes; Su teaches an imaging apparatus that has an optical window is exposed from the shell of the imaging apparatus with its center as the entrance for the imaging optics and its peripheral as the window for projecting the illumination light. Su teaches of Fig. 1 – 23 of applicant’s a first opening through which external light passes and a second opening through which light emitted from the lighting unit passes (paragraph 0029 imaging apparatus, in FIG. 5, is for captured images where the front part of its imaging and lighting optics 501 is removed or replaced with other functioning modules which contain different optics. A special optical window is exposed from the shell of the imaging apparatus with its center 503 as the entrance for the imaging optics and its peripheral 504 as the window for projecting the illumination light such that a first opening through which external light passes through center 503 as the entrance for the imaging optics and a second opening through which light emitted at the peripheral 504 as the window for projecting the illumination light from the lighting unit passes). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the circuitry of Yasutake in a manner similar to Su. Doing so would result improving Yasutake invention in a similar way as Su - namely the ability to provide imaging apparatus that has an optical window is exposed from the shell of the imaging apparatus with its center as the entrance for the imaging optics and its peripheral as the window for projecting the illumination light, in Su invention, to the image sensor in a lens that receives light from an infrared illumination in an opening in a light-shielding unit in Yasutake invention. Regarding claim 6 of the combination of Yasutake in view of Su, Su further teaches of applicant’s wherein the first opening has a shape that does not block light passing through the lens unit (paragraph 0029 imaging apparatus, in FIG. 5, is for captured images where the front part of its imaging and lighting optics 501 is removed or replaced with other functioning modules which contain different optics. A special optical window is exposed from the shell of the imaging apparatus with its center 503 as the entrance for the imaging optics and its peripheral 504 as the window for projecting the illumination light such that the first opening of special optical window is exposed from the shell of the imaging apparatus with its center 503 has a shape that does not block light passing through the peripheral 504 as the window for projecting the illumination of the lens unit imaging and lighting optics 501). Regarding claim 7 of the combination of Yasutake in view of Su, Su further teaches of applicant’s wherein the second opening has a shape that does not block light emitted from the lighting unit (paragraph 0029 imaging apparatus, in FIG. 5, is for captured images where the front part of its imaging and lighting optics 501 is removed or replaced with other functioning modules which contain different optics. A special optical window is exposed from the shell of the imaging apparatus with its center 503 as the entrance for the imaging optics and its peripheral 504 as the window for projecting the illumination light such that the second opening of the peripheral 504 as the window for projecting the illumination has a shape that does not block light emitted from the lighting unit inside imaging and lighting optics 501). Regarding claim 9 the combination of Yasutake in view of Su further teaches of applicant’s wherein the lighting unit includes a light emitting element fixed to the lens holder and a lighting lens that is detachable from the lens holder (Yasutake in paragraph 0024 the infrared illumination unit 12 with the infrared illumination 12a is connected to the lens barrel holder 904.
