Detailed Action Claim Rejections – 35 U.S.C. 103 The following is a quotation of 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, 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.

Claims 8, 9 and 11-13 rejected under 35 U.S.C. 103 as being unpatentable over Kim and Kim0, in view of Jung (KR 20060006121) of record, in view of Do (U.S. Patent Pub. No. 2016/0172339) of record Regarding Claim 8 Kim as modified by Kim0 discloses Claim 7. Kim as modified by Kim0 is silent with respect to “the coating layer comprises a material having a second polarity that is opposite to the first polarity” and “a second coating layer in the first area; and the light emitting element is on the second coating layer”. FIG. 6 Jung discloses a similar display device, wherein the coating layer comprises a material (440) having a second polarity (442 has hydrophilicity) that is opposite to the first polarity (hydrophobic). It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to modify the device of Kim, as taught by Jung. The ordinary artisan would have been motivated to modify Kim in the above manner in order that the solution can better enter into the opening. Modified Kim is silent with respect to “a second coating layer in the first area; and the light emitting element is on the second coating layer”. FIG. 5 Do discloses a similar display device, comprising a second coating layer (40) in the first area; and the light emitting element is on the second coating layer. It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to modify the device of Kim, as taught by Do. The ordinary artisan would have been motivated to modify Kim in the above manner for purpose of preventing the LED devices from being aggregated ([0112] of Do). Regarding Claim 9 Jung discloses the first polarity is hydrophobic (425), and the second polarity is hydrophilic (442). Regarding Claim 11 Modified Kim discloses the second coating layer is to cover the first electrode and the second electrodes which are in the first area; and the opening is on the second coating layers and exposes at least a portion of each of the first electrode and the second electrode of the first area.

Claim 10 rejected under 35 U.S.C. 103 as being unpatentable over Kim, Kim0, Jung and Do, in view of Kuma (CN 100474654) of record. Regarding Claim 10 Kim as modified by Kim0, Jung and Do discloses Claim 9. Kim as modified by Kim0, Jung and Do is silent with respect to “the first coating layer comprises a polymer containing fluorine”. Kuma discloses a similar coating layer, wherein the first coating layer comprises a polymer containing fluorine (Claim 1). It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to modify the device of Kim, as taught by Kuma. The ordinary artisan would have been motivated to modify Kim in the above manner, because such material substitution or replacement would have been considered a mere substitution of art-recognized equivalent values (hydrophobic), MPEP 2144.06. Pertinent Art Shibata (U.S. Patent Pub. No. 2012/0326181) discloses a display device comprising: a substrate (200) in which a first area and a second area, which is an area other than the first area, are defined; a first electrode (401) and a second electrode (402) at least partially spaced apart from each other in the first area on the substrate; a coating layer (420) covering at least a portion of each of the first electrode and the second electrode on the substrate; and at least one light emitting element (410) between the first electrode and the second electrode in the first area.

Kimura (U.S. Patent Pub. No. 2008/0191227) and KR 20160050341 Response to Arguments Applicant’s arguments with respect to Claims 1 and 19 have been considered but are moot because the arguments do not apply to any of the references being used in the current rejection. The Examiner further notes that the limitation “to physically separate the light emitting element from the first and second electrodes” requires the first and second electrodes do not directly contact the light emitting element. Conclusion 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).
