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.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Yoneda et al. (US 2013/0119416 A1; hereinafter “Yoneda”) in view of Aoki et al. (US 2022/0310965 A1; hereinafter “Aoki”).
Regarding claim 1, Yoneda teaches an Organic Light-Emitting Diode (OLED) display device (an organic EL display) (paragraph 38), comprising: a red light-emitting structure (a red light-emitting structure including 7r), a green light-emitting structure (a green light-emitting structure including 7g), and a blue light-emitting structure (a blue light-emitting structure including 7b) (Fig. 1 and paragraphs 38-42), wherein respective layers of the blue light-emitting structure includes a third anode (a reflective electrode 3), a third cathode (a transparent electrode 9), a blue OLED light-emitting block (a light-emitting layer 7b for blue light) located between the third anode and the third cathode (Fig. 1 and paragraphs 39-40).
Yoneda does not teach that the blue light-emitting structure further includes a third electron barrier layer and a third hole barrier layer. Aoki teaches an Organic Light-Emitting Diode (OLED) display device (a display device using an organic electroluminescence (EL) light-emitting material) (Figs. 1-4 and paragraphs 3 and 26) comprising: a blue light-emitting structure (PXB) (Fig. 4 and paragraphs 26 and 58-61), wherein the blue light emitting structure includes an electron barrier layer (an electron blocking layer EBY) located between an anode (PE) and a blue OLED light-emitting block (ELb) and a hole barrier layer (a hole blocking layer HBY) located between a cathode (CE) and the blue OLED light-emitting block (ELb) (Fig. 4 and paragraph 61). Aoki teaches that the electron blocking layer EBY stores the electrons injected from the cathode and prevents the electrons from leaking out to the hole transport layer HTY and the hole blocking layer HBY stores the holes injected from the anode and prevents the holes from leaking out to the electron transport layer ETY (paragraphs 63-64). Therefore, it would have been obvious to one of ordinary skill in the art to combine the teaching of Yoneda with that of Aoki in order to provide the electron and hole blocking layers to prevent electrons and holes leaking out to adjacent hole and electron transport layers.
Yoneda in view of Aoki teaches each and every limitation of the OLED display device structurally and compositionally identical to that of claim 1 as discussed above. Yoneda in view of Aoki also teaches “respective layers” for the red and green light-emitting structures (See claim 2 below and Aoki, Fig. 4 for teaching EBY and HBY for both PXR and PXG). Furthermore, claim 1 does not require any additional feature to distinguish over Yoneda in view of Aoki teaching the OLED display device identical to that of the invention. As such, claimed properties or characteristics (i.e., “wherein (n3z-n3xy) - (n1z-n1xy) ≥ a first preset value, and (n3z-n3xy) - (n2z-n2xy) ≥ a second preset value…n3xy is a sum of refractive indexes of the respective layers of the blue light-emitting structure in the direction perpendicular to the thickness direction”) is presumed to be at least obvious: Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established.

Therefore, it would have been obvious to one of ordinary skill in the art to combine the teaching of Yoneda with that of Aoki in order to provide the electron and hole blocking layers to prevent electrons and holes leaking out to adjacent hole and electron transport layers.
Yoneda in view of Aoki teaches each and every limitation of the OLED display device structurally and compositionally identical to that of claim 12 as discussed above. Yoneda in view of Aoki also teaches “respective layers” for the red and green light-emitting structures (See claim 15 below and Aoki, Fig. 4 for teaching EBY and HBY for both PXR and PXG). Furthermore, claim 12 does not require any additional feature to distinguish over Yoneda in view of Aoki teaching the OLED display device identical to that of the invention. As such, claimed properties or characteristics (i.e., “wherein (n3z-n3xy) - (n1z-n1xy) ≥ a first preset value, and (n3z-n3xy) - (n2z-n2xy) ≥ a second preset value…n3xy is a sum of refractive indexes of the respective layers of the blue light-emitting structure in the direction perpendicular to the thickness direction”) is presumed to be at least obvious: Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established.
