Office Action

§102 §103
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 . Response to Amendment Receipt is acknowledged of applicant' s amendment filed 11/18/2025. Claim 18 cancelled, Claims 1-17 and 19-20 are pending and an action on the merits is as follows. Response to Arguments Applicant's arguments filed 11/18/2025 have been fully considered but they are not persuasive. Title of Specification Applicant has not provided reasoning for not amending the title as such objection remains. 102 & 103 rejection The applicant on page 9 of remarks recites “the cited portions of Kim disclose that all of the light emitting elements LD1, LD2, and LD3 emit light of the same color, rather than two of the light emitting elements emitting one color and another one of the light emitting elements emitting a different color. Thus, the cited portions of Kim fail to disclose, teach, or even suggest "each of two sub-pixels among the first sub-pixel, the second sub-pixel, and the third sub- pixel includes a light emitting element emitting light of the third color,….” The examiner has considered the applicant’s argument but respectfully does not agree with the applicants characterization of the Kim reference. Granted in the cited embodiment the LD1, LD2, LD3 portions are blue e-mitting but Kim does not limit the invention too this. KIM recites the following” [0108] In an embodiment, the first, second, and third light emitting elements LD1, LD2, and LD3 may emit light of the same color or different colors. For example, all of the first, second, and third light emitting elements LD1, LD2, and LD3 may be formed of blue light emitting diodes, which emit blue light.” Just like in paragraph 184, in an embodiment Kim chooses to use blue light but one of ordinary skill would not be led to believe only blue light emitting elements could be used. Clearly Kim anticipates the reference claims 1-16, and applicant is reminded to take the disclosure as a whole when referring to prior art. (Moreover, in paragraph 184, Kim demonstrates, the use of blue light; However, one of ordinary skill would understand that not only blue light emitting elements could be used).Furthermore the term “may” give the idea of choice since clearly in paragraph 108 one is given a choice of LD1, LD2, LD3 the invention is not considered novel. Dummy Bank The applicant On page 10 of remarks “ However, as illustrated in the non-limiting embodiment of FIG. 17 of the present application, reproduced below, the 'dummy bank' (D_BNK) is a structure formed separately from the 'bank' (BNK). In contrast, as illustrated in FIG. 11 of Kim, reproduced below, Kim merely discloses the patterning of a single partition wall (PW), and there is no motivation, teaching, or suggestion in Kim to form an additional dummy bank on its partition wall (PW)” Examiner again respectfully disagrees with the applicant and notes the applicant is taking a single embodiment and making conclusionary statements. Examiner notes the hat the rejection of the Dummy Bank was written under 103 and that further support for this is as follows Kim recites paragraphs 120-121 “…in embodiments of the present disclosure, the partition wall PW may have various suitable peripheral shapes corresponding not only to a rectangular shape but also to a polygonal shape, a circular shape, an elliptical shape, or a combination thereof. In other words, for example, the shape, size, and/or arrangement structure of the partition wall PW may be changed in various suitable ways depending on the embodiments…in an embodiment, the partition wall PW may have a multi-layer structure including one or more organic layers and one or more inorganic layers, whereby the height of the partition wall PW may be easily adjusted” . The examiner take as the position that one of ordinary skill would not readily see this as a “simple” as the applicant alleged but based upon the teachings of Kim’s disclosure the partition can be in two parts if required. Furthermore reflectivity can be imparted to the partition wall as well as patterning for conversion layers which improves optical efficiency while preventing color mixing, Applicant alleges that since Kim does not mention color mixing there is no motivation present for the modification; the examiner disagrees for the reasoning provided. All arguments believe to be addressed. Rejections remain for claims 1-16. Updated search for claims 17 and 19-20 in light of amendment. Specification 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. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

Patentability shall not be negated by the manner in which the invention was made. Claims 6-8, 11-12, 17 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim (US 20200013766 A1). Regarding claim 6, Kim fails to explicitly disclose wherein the first sub-pixel further includes a dummy bank disposed on the bank, corresponding to the first non-emission area. Kim rather discloses on Partition Wall which extends upwards to the capping layer to adequately prevent light leakage in the device . One of ordinary skill in the art could readily derive before the effective filing date to modify the display device of Kim as taught by Kim wherein the first sub-pixel further includes a dummy bank disposed on the bank, corresponding to the first non-emission area the motivation being to prevent light mixing at unwanted boundaries. Regarding claim 7, Kim discloses (Figures 1-9) (Figure 7), wherein the first sub-pixel (SPX1) further includes a capping layer(CPL1) disposed between the first color conversion layer (CCL1) and the color filter (CF1). Regarding claim 8, Kim discloses (Figure 10) wherein the capping layer (CPL) is disposed directly on the first color conversion layer(CCL1) and the dummy bank (Partition Wall, PW) (see rejection claim 6). Regarding claim 11, Kim fails to explicitly disclose wherein the second sub-pixel further includes a dummy bank disposed on the bank, corresponding to the second non-emission area. Kim rather discloses on Partition Wall which extends upwards to the capping layer to adequately prevent light leakage in the device . One of ordinary skill in the art could readily derive before the effective filing date to modify the display device of Kim as taught by Kim wherein the first sub-pixel further includes a dummy bank disposed on the bank, corresponding to the first non-emission area the motivation being to prevent light mixing at unwanted boundaries thus increasing light efficiency. Regarding claim 12 Kim discloses (Figures 10-16) wherein the second sub-pixel further includes a capping(CPL2) layer disposed on partition wall (PW)(see rejection six and 11) and the first light scattering layer (CCL2 and π203). Regarding claims 17 and 19-20, these claims the rejections of claims 1-16 apply mutatis mutandis to overcome these limitations of these claims.
