CTNF 18/845,607 CTNF 85131 DETAILED ACTION 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. Information Disclosure Statement The information disclosure statement (IDS) submitted on 09/10/2024, 08/01/2025, 09/30/2025, 02/02/2026, 03/06/2026, and 04/27/2026 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Objection/s to the Specification 06-11 AIA The title of the invention, “LENS UNIT AND LAYERED FILM,” is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Claim Rejections - AIA 35 USC § 103 07-06 AIA 15-10-15 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 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. 07-20-02-aia AIA This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. 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 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. 07-21-aia AIA Claim s 1-4, 6-8, and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Le (US 20210215865 A1) in view of He (US 20210294105 A1) and in further view of Hokazono (KR 20080083070 A) . Regarding claims 1 and 10, Le teaches a lens unit and a method to be used in a display system configured to display an image to a user, the lens unit and method (Fig. 1-14) comprising: a reflection-type polarizing member (630) configured to reflect light, which has been emitted toward a front side from a display surface of a display element (604) configured to display the image, and has passed through a polarizing member (691) and a first λ/4 member (685; [0088]); a first lens portion (610/611) arranged on an optical path between the display element (604) and the reflection-type polarizing member (630); a half mirror (620; [0032]) arranged between the display element (604) and the first lens portion (610/611), the half mirror (620) being configured to transmit the light emitted from the display element (604) and to reflect the light reflected by the reflection-type polarizing member (630) toward the reflection-type polarizing member (630); a second λ/4 member (625, [0088]) arranged on an optical path between the half mirror (620) and the reflection-type polarizing member (630); a protective member/laminate film (anti-reflective coating 629), arranged on an optical path between the half mirror (620) and an absorptive polarizer (661), and wherein the protective member/laminate film (anti-reflective coating 629) is brought into contact with a space formed between the protective member/laminate film (anti-reflective coating 629) and at least one of the first lens portion (611) or the absorptive polarizer (661). Le further teaches one or more lenses in the optical system ([0047]) but does not explicitly teach a second lens portion arranged on the front side of the reflection-type polarizing member (630). He teaches a second lens portion (26-3) arranged on the front side of the reflection-type polarizing member (30) and an absorptive polarizer (34). It would have been obvious to a person of ordinary skills in the art at the time of the invention to combine Le with He, which results in the protective member/laminate film (anti-reflective coating 629) arranged on the optical path between the half mirror (620 of Le) and the second lens portion (26-3 of He); because it provides optically superior design ([0058], [0084]). Neither Le nor He teaches the protective member/laminate film (anti-reflective coating 629) having a maximum value for a 5° specular reflectance spectrum of 1.2% or less in a wavelength range of from 420 nm to 680 nm. Hokazono teaches an anti-reflective film having a maximum value for a 5° specular reflectance spectrum of 1.2% or less in a wavelength range of from 420 nm to 680 nm (p. 4, 9, 32 of the translation). It would have been obvious to a person of ordinary skills in the art at the time of the invention to combine Le and He with Hokazono; because the anti-reflective film provided by Hokazono is superior in quality and lower in cost. Regarding claim 2, the combination of Le, He and Hokazono, consequently results in the protective member (anti-reflective coating of Hokazono) has a 5° specular reflectance at a wavelength of 450 nm of 0.3% or less in average value in measurement (p. 4, 9, 32 of the translation). Regarding claim 3, the combination of Le, He and Hokazono, consequently results in the protective member (anti-reflective coating of Hokazono) has a 5° specular reflectance at a wavelength of 600 nm of 0.3% or less in average value in measurement (p. 4, 9, 32 of the translation). Regarding claim 4, the combination of Le, He and Hokazono, consequently results in the protective member (anti-reflective coating) has a surface smoothness of 0.5 arcmin or less, i.e., roughness RA 6.3µm (p. 7, 13, 21 of Hokazono). Regarding claim 6, Le, as combined with He and Hokazono, further teaches the lens unit comprises a laminate portion including the second λ/4 member (625), the reflection-type polarizing member (630), and the protective member (629; Fig. 6). Regarding claim 7, Le, as combined with He and Hokazono, further teaches the laminate portion includes an absorption-type polarizing member (661) arranged between the reflection-type polarizing member (630) and the protective member (anti-reflective coating 629; [0088]). Regarding claim 8, Le, as combined with He and Hokazono, further teaches the laminate portion includes a third λ/4 member (663) arranged between the reflection-type polarizing member (630) and the protective member (anti-reflective coating 629; [0088]) . 07-21-aia AIA Claim s 5 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over Le in view of He and Hokazono in further view of Teijin PURE-ACE RM . Regarding claim 5, Le, as combined with He and Hokazono, further teaches the second λ/4 member (625) being a Teijin FM-143 ([0088]). Teijin FM-143 does not specify Re(450) < Re(550). Teijin PURE-ACE RM specifies Re(450) < Re(550) ( see RE(λ)/Re(550nm) chart; p. 08). It would have been obvious to a person of ordinary skills in the art at the time of the invention to further modify Teijin FM-143 with Teijin PURE-ACE WRF-S; because Teijin PURE-ACE RM offers better performance and newer. Regarding claim 9, Le, as combined with He and Hokazono, further teaches the third λ/4 member (663) being a Teijin FM-143 ([0088]). Teijin FM-143 does not specify Re(450) < Re(550). Teijin PURE-ACE RM specifies Re(450) < Re(550) ( see RE(λ)/Re(550nm) chart; p. 08). It would have been obvious to a person of ordinary skills in the art at the time of the invention to further modify Teijin FM-143 with Teijin PURE-ACE WRF-S; because Teijin PURE-ACE RM offers better performance and newer. Conclusion The prior art references cited in PTO-892 are made of record and considered pertinent to applicant's disclosure.
