Office Action

§112
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 Claims 1 – 5, and 13 – 14 are allowable. The restriction requirement between inventions, as set forth in the Office action mailed on 01/29/2025, has been reconsidered in view of the allowability of claims to the elected invention pursuant to MPEP § 821.04(a). The restriction requirement is hereby withdrawn as to any claim that requires all the limitations of an allowable claim. Specifically, the restriction requirement of 01/29/2025 is partially withdrawn. Claims 6 - 12 and 15, directed to species 2A and 2B are no longer withdrawn from consideration because the claim(s) requires all the limitations of an allowable claim. However, claims 16 - 22, directed to species 1, and 3 - 6 are withdrawn from consideration because they do not all require all the limitations of an allowable claim. In view of the above noted withdrawal of the restriction requirement, applicant is advised that if any claim presented in a divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application. Once a restriction requirement is withdrawn, the provisions of 35 U.S.C. 121 are no longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01. Information Disclosure Statement The information disclosure statement (IDS) was submitted on 02/02/2026. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Drawings The drawings are objected to under 37 CFR 1.83(a) because they fail to show a color filter disposed on the color conversion layer only within an emission area defined by the recessed portion and contacting the second electrode as described in the specification. Specifically, figures 5A – 5B show the color filter present on the color conversion layer, and figure 5B shows the color filter present in a limited space and in the emission area defined by the recessed portion. However, figure 5B appears to also show that the color filter extends into the non-emission areas NEA. Figure 5B appears to be the only drawing that shows the color filter inside the protrusion, but also shows the color filter not limited to just the emission area EA and that the color filter CF extends into the non-emission area NEA. The non-emission area and emission area should be corrected to show the color filter only being inside the emission area. Any structural detail that is essential for a proper understanding of the disclosed invention should be shown in the drawing. MPEP § 608.02(d). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. 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 15 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 15 recites the limitation "an emission area" in line 4 of claim 15. There is insufficient antecedent basis for this limitation in the claim. Claim 15 depends on claim 1. Claim 1 already claims an emission area defined by the recessed portion. It is unclear if the emission area as claimed in claim 15 is the same emission area as the emission area in claim 1, as the two claims both state “an emission area” and provide two different ways of defining the emission area. As it is unclear if the emission area in claim 15 is the same emission area as in claim 1, claim 15 is rejected as being indefinite. Allowable Subject Matter Claims 1 – 14 are allowable primarily because the references of record, alone or in combination, do not anticipate or render obvious the limitations noted therein. For example, independent claim 1’s “…and wherein the light conversion pattern comprises a color conversion layer disposed directly on the second electrode over the recessed portion and provided in a form filling the recessed portion, and a color filter disposed on the color conversion layer only within an emission area defined by the recessed portion and contacting the second electrode”. Claims 2 – 14 are allowable primarily as depending on an allowable base claim. Any comments considered necessary by applicant MUST be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance”. Claim 15 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. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20220352132 A1 teaches a display device with a light blocking layer including a protrusion, an LED inside the protrusion, and an electrode in direct contact with one of the LED and inside the protrusion. It does not appear to teach the color converting layer inside the protrusion and a color filter only within the emission area. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
