(figure 1A and 1B) Claim Rejections - 35 USC § 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. Claim(s) 10-12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. Kim fails to teach: 10. The display device of claim 9, wherein the separator includes: a first separator disposed on the first pixel defining layer; and a second separator disposed on the second pixel defining layer. 11. The display device of claim 10, wherein the auxiliary electrode is disposed on at least one of the first separator and the second separator. 12. The display device of claim 11, wherein the auxiliary electrode includes: a first auxiliary electrode disposed on the first separator; and a second auxiliary electrode disposed on the second separator, and the first auxiliary electrode and the second auxiliary electrode are electrically connected to each other. In regards to claims 10-12, In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960) (Claims at issue were directed to a water-tight masonry structure wherein a water seal of flexible material fills the joints which form between adjacent pours of concrete. The claimed water seal has a "web" which lies in the joint, and a plurality of "ribs" projecting outwardly from each side of the web into one of the adjacent concrete slabs. The prior art disclosed a flexible water stop for preventing passage of water between masses of concrete in the shape of a plus sign (+). Although the reference did not disclose a plurality of ribs, the court held that mere duplication of parts has no patentable significance unless a new and unexpected result is produced.) Claim(s) 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al as applied to claim 1 above, and further in view of Shin, KWANGHOON EP 3840052 A1. Kim fails to teach: 19. The display device of claim 1, wherein the circuit layer includes an auxiliary wire that applies a driving voltage to the light emitting element, and the auxiliary electrode and the auxiliary wire are electrically connected to each other. Shin teaches: The circuit element layer is formed on the substrate 100 and may include circuit elements (e.g., transistors and capacitors) and wires constituting the pixel PX. A first conductive layer 120 may be disposed on the substrate 100. The first conductive layer 120 may include a light blocking layer 121, a lower electrode 122 of the storage capacitor Cst, and an auxiliary wire 123. See Figure 3 and para 0063 Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Shin, with the primary reference of Kim, because [t]he auxiliary wire 123 may be connected to a second power line PL2 to which the low potential driving voltage ELVSS is applied. Para 0063 Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 2022/271115 A1 HARADA, KENJI teaches: in fig. 4 an OLED panel comprising a PDL (1212) with an auxiliary electrode CAW on top of it. The CAW is a three layer laminate formed of metal such as Ti/Al/Ti, see para. 68. Ti and Al are reflective metals. The auxiliary electrode is electrically connected to the cathode E2 via layer UL. The layer 1212, which correspond to the partition wall, has different heights. A first portion can be defined at an outer region and a second portion at a region where layer 1212 is highest. And: US 2021/104587 A1 MOON, JUNHWAN et al teaches: a circuit layer TFT disposed on a base substrate 100; a light emitting element (see figure, three OLEO shown) disposed on the circuit layer TFT and corresponding to a light emitting area; a partition wall 182 disposed on the circuit layer, disposed corresponding to a non-light emitting area adjacent to the light emitting area, and including a first portion (outer portion with less height, can be chosen arbitrarily) and a second portion (center portion where barrier layer 1212 has maximum height) having a greater thickness than a thickness of the first portion; and an auxiliary electrode disposed on the second portion of the partition wall and including a reflective material, wherein the auxiliary electrode 192 is electrically connected to an electrode 230 of the light emitting element.
