Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status 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 filed 08/25/2025 fails to comply with 37 CFR 1.98(a)(1), which requires the following: (1) a list of all patents, publications, applications, or other information submitted for consideration by the Office; (2) U.S. patents and U.S. patent application publications listed in a section separately from citations of other documents; (3) the application number of the application in which the information disclosure statement is being submitted on each page of the list; (4) a column that provides a blank space next to each document to be considered, for the examiner’s initials; and (5) a heading that clearly indicates that the list is an information disclosure statement. The information disclosure statement has been placed in the application file, but the information referred to therein has not been considered. The information disclosure statement filed 08/25/2025 fails to comply with 37 CFR 1.98(a)(3)(i) because it does not include a concise explanation of the relevance, as it is presently understood by the individual designated in 37 CFR 1.56(c) most knowledgeable about the content of the information, of each reference listed that is not in the English language. It has been placed in the application file, but unless listed on the 1449, the information referred to therein has not been considered. Claim Rejections - 35 USC § 112 Claims 1-13 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Independent claim 1 recites “the other portion” in line 12. There is insufficient antecedent basis for this limitation in the claims. Independent claim 1 recites “the other pixel electrode” in line 14. There is insufficient antecedent basis for this limitation in the claims. Other pending claims are indefinite by virtue of dependency from at least one indefinite claim. Allowable Subject Matter Claims 1-13 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. See statement of reasons for the indication of allowable subject matter in the non-final rejection mailed 03/18/2025 Response to Arguments Applicant's arguments filed 11/12/2025 have been fully considered but they are not persuasive. There is presently no antecedent for “the other portion”. There is presently no antecedent for “the other pixel electrode”. There is presently no “Figure 4” Furthermore, many features of Fig. 4C appear too crowded to discern.
