DETAILED ACTION General Remarks The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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. When responding to this office action, applicants are advised to provide the examiner with line numbers and page numbers in the application and/or references cited to assist the examiner in locating appropriate paragraphs. Per MPEP 2111 and 2111.01, the claims are given their broadest reasonable interpretation and the words of the claims are given their plain meaning consistent with the specification without importing claim limitations from the specification. For Examiner’s Interview fill out the online Automated Interview Request (AIR) form (http://www.uspto.gov/patent/uspto-automated-interview-request-air-form.html). Status of claim(s) to be treated in this office action: Independent: 1 and 20. Pending: 1-20. Withdrawn: 12. Information Disclosure Statement Applicant’s IDS(s) submitted on 11/17/2023 and 9/6/2024 is/are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has/have considered by the examiner and made of record. Election/Restrictions Applicant’s election without traverse of Species I (fig. 10 and 13) claim 1-11 and 13-20 in the reply filed on 2/6/2026 is acknowledged. Specification The disclosure is objected to because of the following informalities: The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. The following title is suggested: DISPLAY DEVICE WITH DEMULTIPLEXER SWITCH CIRCUITS AND INTERVENING SHIELD LINES. Claim Rejections - 35 USC § 103 The following is a quotation of AIA 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. Claim(s) 1-10, 14-15 and 20 is/are rejected under AIA 35 U.S.C. 103 as being unpatentable over Cho et al., US PG pub. 20200357345 A1 (Cho’345); in view of Cho et al., US PG pub. 20210273035 A1 (Cho’035).
