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 . Election/Restrictions Applicant's election with traverse of Group II (claims 11-20) and Species I (Figs. 3A-3L) in the reply filed on 09/24/2025 is acknowledged. The traversal is on the ground(s) that concurrent searching of the two groups and different species would place no undue search or examination burden on the Office. This is not found persuasive because the two groups belong to different classifications, and the different species require a different field of search, i.e. employing different search strategies or search queries. Thus, the different groups and the different species place undue burden on the examiner. The requirement is still deemed proper and is therefore made FINAL. Claims 1-10 and 13-14 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention or species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 09/24/2025. Claims 13 and 14 with limitations related to “the first positive photoresist portion”, “the second positive photoresist portion”, and “the third positive photoresist portion”, reads on the nonelected Species II of Figs 4A-4P of Category I and does not read on the elected Species I of Figs. 3A-3L of Category I, and thus is withdrawn from further consideration. Information Disclosure Statement The information disclosure statements (IDS) submitted on 11/15/2022 and 04/19/2023 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 20 is 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. Claim 20 recites the limitation "the first, the second and the third color selector" in the second line and the third line of the claim. There is insufficient antecedent basis for this limitation in the claim. Allowable Subject Matter Claims 11-12 and 15-19 are allowed. The following is a statement of reasons for the indication of allowable subject matter: The prior art of record does not teach or suggest, singularly or in combination, at least the limitations of "forming a first via in a matrix material; depositing a first plurality of quantum dots in the first via to form a first portion of the color conversion material layer corresponding to a first color; forming a second via in the matrix material; depositing a second plurality of quantum dots in the second via to form a second portion of the color conversion material layer corresponding to a second color; forming a third via in the matrix material; and depositing a third plurality of quantum dots in the third via to form a third portion of the color conversion material layer corresponding to a third color, wherein the first plurality of quantum dots are located over a first light emitting diode, the second plurality of quantum dots are located over a second light emitting diode, and the third plurality of quantum dots are located over a third light emitting diode" as recited in claim 11. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Lalicki et al. (US 2017/0030555 A1) teach depositing light-converting materials directly on the an array of LEDs.
