CTFR 18/174,684 CTFR 97230 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Response to Amendment The Amendment filed February 04, 2026 has been entered. Response to Arguments 07-37 AIA Applicant's arguments filed February 04, 2026 have been fully considered but they are not persuasive. In response to applicant’s arguments on page 2, that Glensbjerg fails to teach or suggest, at least, an illuminator that is configured to emit parallel light using wavelengths of 400 nm or longer, the parallel light including at least two or more different wavelength spectra of light. It is pointed out to the applicant that Glensbjerg does teach an illuminator that is configured to emit parallel light using wavelengths of 400 nm or longer (fig. 5, col. 5, lines 52-53 ), but fails to disclose at least two or more different wavelength spectra of light. However, Zuzak teaches at least two or more different wavelength spectra of light ( [0170]: broadband illumination source ). The combination of both Glensbjerg and Zuzak teaches or make obvious an illuminator that is configured to emit parallel light using wavelengths of 400 nm or longer, the parallel light including at least two or more different wavelength spectra of light . Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-23-aia AIA The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 07-21-aia AIA Claim 1, 5-9, 12 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Glensbjerg (US 10921234 B2) in view of Zuzak (US 20130296709 A1) .

Glensbjerg, when modified by Zuzak, fails to disclose the parallel light having an angle of divergence of not more than tan -1 (d/f), where f represents a focal length of the illumination lens and d represents a diameter of the illumination lens.

Therefore the obstruction 511 has the same or larger size than a size of projection of source 503 ). Regarding claims 7 and 8, Glensbjerg, when modified by Zuzak, teaches the optical imaging apparatus according to claim 6, wherein the light-blocking region has a circular shape (( claim 6: the obstruction comprises an opaque centre (that aligns with conventional circular obstructions) surrounded by an at least partly transparent area ), and wherein in a case where an angle θ of diffraction to the target is known, f’ × tan θ is larger than a size of a radius of the light-blocking region, where f’ represents a focal length of the lens ( the displacement of the dispersed light at angle θ at the focal plane is f’ × tan θ, this displacement is bigger than the radius of the blocking region as shown in fig. 5, otherwise, all light would be blocked ).

However, the use of a mirror to direct light within a solvent is well known as disclosed Sangu ([0165]). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to modify Glensbjerg and Zuzak by incorporating a mirror provided between the illuminator and the lens in the solvent along an optical path of both the parallel light and the diffracted light, and configured to reflect both the parallel light and the diffracted light in the solvent toward the lens, the aperture, and the imaging element in order to provide a desired optical path length . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 16 (which depends on claim 1), 18 (which depends on claim 9), 19 (which depends on claim 12) and 20 (which depends on claim 15) are 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. 13-03-01 AIA The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 16 and 18: The prior art of record taken alone or in combination, fails to teach “ comprising a storage medium or a cloud server configured to store a relationship between at least one of a concentration ratio p, a temperature, and a density of the target, and a ratio y = (average of hues near a first peak of the hue histogram) / (average of hues near a second peak of the hue histogram), wherein the processing apparatus is configured to calculate the y value and estimate at least one of the concentration ratio p, the temperature, and the density of the target corresponding to the y value stored in the storage or the cloud server. ” Regarding claim 19: The prior art of record taken alone or in combination, fails to teach “ comprising storing a relationship between at least one of a concentration ratio p, a temperature, and a density of the target, and ratio y = (average of hues near a first peak of the hue histogram) / (average of hues near a second peak of the hue histogram) in a storage or a cloud server, wherein the estimating includes calculating the y value and estimating the at least one of the concentration ratio p, the temperature, and the density of the target corresponding to the y value stored in the storage or the cloud server ” Regarding claim 20: The prior art of record taken alone or in combination, fails to teach “ storing a relationship between at least one of a concentration ratio p, a temperature, and a density of the target, and a ratio y = (average of hues near a first peak of the hue histogram) / (average of hues near a second peak of the hue histogram) in a storage or a cloud server, wherein the estimating includes calculating the y value and estimating the at least one of the concentration ratio p, the temperature, and the density of the target corresponding to the y value stored in the storage or the cloud server ” Glensbjerg, when modified by Zuzak, teaches the optical imaging apparatus according to claim 4, comprising a storage medium ( computer inherently has a storage medium ) ( col. 21, lines 25-30 ) or a cloud server, Glensbjerg teaches correlating the results of the processing to the at least one quantity parameter and/or the at least one quality parameter of biological particles in a liquid sample ( col. 8, lines 13-15 ), however Glensbjerg does not disclose comprising a storage medium or a cloud server configured to store a relationship between at least one of a concentration ratio p, a temperature, and a density of the target, and a ratio y = (average of hues near a first peak of the hue histogram) / (average of hues near a second peak of the hue histogram), wherein the processing apparatus is configured to calculate the y value and estimate at least one of the concentration ratio p, the temperature, and the density of the target corresponding to the y value stored in the storage or the cloud server. The prior art of record fails to disclose “comprising a storage medium or a cloud server configured to store a relationship between at least one of a concentration ratio p, a temperature, and a density of the target, and a ratio y = (average of hues near a first peak of the hue histogram) / (average of hues near a second peak of the hue histogram), wherein the processing apparatus is configured to calculate the y value and estimate at least one of the concentration ratio p, the temperature, and the density of the target corresponding to the y value stored in the storage or the cloud server.” Conclusion 07-40 AIA Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action.
