Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant’s submission filed on 08/20/2026 has been entered. III. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. A. Claim 1, 3, 4, 8, 10, 11, and 20-22 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US 2024/0065094 (“Ji”), as evidenced by each of Provisional Application US 63/386,980 (“Provisional Application”) and US 2023/0117045 (“Dyatkin”). At the outset, Ji has priority to each of the Provisional Application (filed 12/12/2022) and non-provisional application 17/959,326 (filed 10/04/2022) which published as pre-grant publication US 2023/0117045 (“Dyatkin”).

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 of this title, 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. A. Claims 1 and 14-16 are rejected under 35 U.S.C. 103 as being unpatentable over Ji as evidenced by the Provisional Application and Dyatkin, and in view of US 2012/0025171 (“Canzler”). Claim 1 reads, in pertinent part, 1. (Currently Amended) An organic light-emitting device, comprising: [1] a first electrode; [2] a second electrode; and [3] an organic layer arranged between the first electrode and the second electrode, wherein [4a] the organic layer comprises [4b] an emission layer and [4c] an n-doped layer, [5] the n-doped layer is arranged between the first electrode and the emission layer, … The prior art of Ji as evidenced by the Provisional Application and Dyatkin, as explained above, teaches each of the features of claim 1. In the rejection above, the cathode 160 in Ji was taken to be the claimed “first electrode”. However, the anode 115 may be taken as the first electrode and the cathode 160 as the second electrode, then Ji does not disclose the limitations of features [4c] and [5] of claim 1. With regard to features [4c] and [5] of claim 1, Canzler, like Ji, teaches an OLED including an anode 2 and cathode 1 with an organic layer 4 therebetween, the organic layer including a sequence of layers, including a light emitting layer EL having an iridium metal complex dopant, e.g., “ORE--iridium(III) bis(2-methyldibenzo-[f,h]quinoxaline)(acetylaceto-nate)”, in a host, e.g. “NPB--N,N % di(naphthalen-2-yl)-N,N'-diphenylbenzidine” (¶ 62), i.e. “20 nm ORE in NPB (10%)” (e.g. Examples 2 and 4 ¶¶ 66, 68). See also Examples 9 and 10 at ¶¶ 73-95) including a light emitting layer with 20 wt% Ir(piq)3 dopant in host BAlq (¶ 92, compound structures on p. 6). The sequence of layers in each of Choung and Ji includes essentially the same, well-known general sequence of an OLED including anode, hole transport layer (HTL), electron blocking layer (EBL), light emitting layer (EML or EL), hole blocking layer (HBL), electron transport layer (ETL), and cathode: [0275] FIG. 1 shows an organic light emitting device 100. The figures are not necessarily drawn to scale. Device 100 may include a substrate 110, an anode 115, a hole injection layer 120, a hole transport layer 125, an electron blocking layer 130, an emissive layer 135, a hole blocking layer 140, an electron transport layer 145, an electron injection layer 150, a protective layer 155, a cathode 160, and a barrier layer 170. Cathode 160 is a compound cathode having a first conductive layer 162 and a second conductive layer 164. (Ji: ¶ 275; ¶ 175 in Dyatkin; Fig. 1 in each) [0044] anode/n-doped ETL/p-doped HTL/EBL/EL/HBL/n-doped ETL/p-doped HTL/cathode [0045] anode/n-doped ETL/p-doped HTL/EBL/EL/HBL/n-doped ETL/cathode. [0047] anode/n-doped ETL/EBL/EL/HBL/p-doped HTL/cathode [0048] anode/n-doped ETL/EBL/EL/HBL/n-doped ETL/cathode (Canzler: ¶¶ 44, 45, 47, 48) Canzler further teaches including an n-doped ETL, i.e. an electron transport material doped with an n-dopant, just as in the Instant Application, which states in this regard, “In one or more embodiments, the n-doped layer may include an electron transport compound and an n-dopant.” (Instant Specification: ¶ 150). Also like the Instant Application (Instant Specification: ¶¶ 150-166), Canzler teaches that the n-dopant can be a metal complex of, e.g. W (¶ 62) or Ru (¶ 88), albeit of different metals than those in the Instant Application. Canzler deposits the n-doped layer directly on the anode (supra) before forming the hole transporting materials and EBL alone or followed by a p-doped layer including a p-dopant in a hole transporting material—also as in the Instant Application (Instant Specification: ¶¶ 171-173). Canzler explains the benefit of including the n-doped layer alone or the n-doped layer/p-doped layer, i.e. a np junction on the anode and a pn junction on the cathode, as increasing free charge carriers available to the organic layer (Canzler: ¶¶ 11-12), which allows lower operating voltage of the OLED compared to OLEDs lacking the np and pn junctions (Canzler: ¶ 13-14) and easier selection of anode and cathode materials (Canzler: ¶ 15). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to include an n-doped layer directly on the anode 115 of Ji, or an n-doped layer/p-doped layer directly on the anode 115 of Ji, at least in order to improve free charge carrier availability and thereby allow lower operation voltage, as taught by Canzler (supra). As such, Canzler may be seen as an improvement to Ji in this aspect. (See MPEP 2143.) This is all of the limitations of claim 1. With regard to claim 14, Ji further discloses, 14. (Original) The organic light-emitting device of claim 1, wherein the organic layer 120-155 further comprises [1] a hole transport region arranged between the first electrode 115 and the emission layer 135, and [2] the hole transport region comprises a hole injection layer 120, a hole transport layer 125, an electron blocking layer 130, a buffer layer, or a combination thereof [Ji: ¶ 275; ¶ 175 in Dyatkin (supra)]. Ji modified to use the n-doped layer or the n-doped layer/p-doped layer of Canzler, as explained above, would still include at least an HTL and EBL between the anode 115 and the emission layer 135. With regard to claim 15, Canzler further discloses, 15. (Previously Presented) The organic light-emitting device of claim 14, wherein the n-doped layer is arranged between the first electrode and the hole transport region [Canzler: ¶¶ 44, 45, 47, 48 (supra)]. Because the n-doped layer is in contact with the anode, Ji modified to use the n-doped layer or the n-doped layer/p-doped layer of Canzler would still include “the n-doped layer … arranged between the first electrode 115 and the hole transport region”, including at least layers the HTL 125 and the EBL 130 as required by claim 15. With regard to claim 16, Ji further discloses 16. (Original) The organic light-emitting device of claim 1, wherein [1] the organic layer 120-155 further comprises an electron transport region 140/145/150 arranged between the emission layer and the second electrode, and [2] the electron transport region 140/145/150 comprises a hole blocking layer 140, an electron transport layer 145, an electron injection layer 150, or a combination thereof [Ji: ¶ 275; ¶ 175 in Dyatkin (supra)]. B. Claims 1 and 17-19 are rejected under 35 U.S.C. 103 as being unpatentable over Ji as evidenced by the Provisional Application and Dyatkin, and in view of US 2007/0046189 (“Hatwar”). Claim 1 reads, in pertinent part, 1. (Currently Amended) An organic light-emitting device, comprising: [1] a first electrode; [2] a second electrode; and [3] an organic layer arranged between the first electrode and the second electrode, wherein [4a] the organic layer comprises [4b] an emission layer and [4c] an n-doped layer, [5] the n-doped layer is arranged between the first electrode and the emission layer, … The prior art of Ji as evidenced by the Provisional Application and Dyatkin, as explained above, teaches each of the features of claim 1. In the rejection above, the cathode 160 in Ji was taken to be the claimed “first electrode”. However, the anode 115 may be taken as the first electrode and the cathode 160 as the second electrode, then Ji does not disclose the limitations of features [4c] and [5] of claim 1. Claim 17 reads, 17. (Original) The organic light-emitting device of claim 1, wherein the organic layer further comprises: [1] n emission units; and [2] n-1 charge generation units arranged between two neighboring emission units, wherein [3] n is an integer of 2 or greater, and [4] at least one of the n emission units comprises the at least one organometallic compound. Ji does not show more than one emission unit in either of Figs. 1 and 2 but does indicate that the Ir complexes disclosed therein can be used in a tandem OLED having a charge generation layer, stating in this regard, h) Charge Generation Layer (CGL) [0320] In tandem or stacked OLEDs, the CGL plays an essential role in the performance, which is composed of an n-doped layer and a p-doped layer for injection of electrons and holes, respectively. Electrons and holes are supplied from the CGL and electrodes. The consumed electrons and holes in the CGL are refilled by the electrons and holes injected from the cathode and anode, respectively; then, the bipolar currents reach a steady state gradually. Typical CGL materials include n and p conductivity dopants used in the transport layers. (Ji: ¶ 320; emphasis added; also Provisional Application at ¶ 204 and Dyatkin at ¶ 221) Ji does not, however, provide the structure of “tandem or stacked OLEDs” (id.) and does not clearly teach all of the limitations of claim 17. Hatwar teaches the known configuration for a tandem OLED 100, 200 (Hatwar: Figs. 1, 2), which includes 17. (Original) The organic light-emitting device of claim 1, wherein the organic layer further comprises: [1] n emission units 120.1 to 120.N; and [2] n-1 charge generation units 130.1 to 130.(N-1) arranged between two neighboring emission units, wherein [3] n is an integer of 2 or greater [i.e. N in Fig. 1 and 2 in Fig. 2], and [4] … [not taught] … Also like Ji, Hatwar teaches that the charge generation layers, e.g. 130.1 in Figs. 2 and 3E, are formed by a n-doped organic layer 331 and a p-doped organic layer 335, wherein the n-doped layer is formed of a n-type dopant, e.g. a metal, and an electron-transporting material (Hatwar: ¶¶ 87-88). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to configure the tandem or stacked OLED of Ji generally as a stack of the organic layers 120-150 of Ji separated by the CGLs of Ji, configured as in Hatwar Figs. 1, 2, and 3E, because Hatwar teaches that this is a known configuration for tandem or stacked OLEDs. So configured, Ji/Hatwar teaches, the limitations of feature [4] of claim 17 and features [4c] and [5] of claim 1, as follows: Claim 17: [4] at least one of the n emission units comprises the at least one organometallic compound [because the Ir complexes of Ji can be used to make the emission layers 135 of each of the emission units]. Claim 1: [4c] an n-doped layer [i.e. the n-doped layer of the CGL], [5] the n-doped layer is arranged between the first electrode 115 and the emission layer 135 [of the 2nd emission unit stacked on the 1st emission unit], This is all of the limitations of claims 1 and 17. With regard to claims 18 and 19, Ji modified according to Hatwar, as explained above, further teaches, 18. (Original) The organic light-emitting device of claim 17, wherein the organic layer further comprises [1] a hole transport region 120/125/130 [of the 2nd emission unit] arranged between the first electrode 115 and the emission layer 135 [of the 2nd emission unit], [2] the hole transport region 120/125/130 [of the 2nd emission unit] comprises a hole injection layer 120, a hole transport layer 125, an electron blocking layer 130, a buffer layer, or a combination thereof, and [3a] …, or [3b] at least one of the n-1 charge generation units comprises the n-doped layer [all of the CGLs include the n-doped layer (supra)]. 19. (Original) The organic light-emitting device of claim 18, wherein [2] the n emission units comprise a kth emission unit which is kth nearest to the first electrode 115, wherein k is an integer from 2 to n [noting Fig. 1 of Hatwar includes N emission units], and [2] the kth emission unit comprises the emission layer comprising the at least one organometallic compound [because the Ir complexes of Ji can be used to make the emission layers 135 of each of the emission units]. C. Claims 1, 3, 4, 8-13, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over US 2014/0008617 (“Beers”) as evidenced by US 7,279,704 (“Walters”). At the outset, Beers incorporates Walters by reference for disclosing the materials making up the layers of the OLED 100 shown in Fig. 1, except for the emissive layer 135 which is the subject of Beers (Beers: ¶ 53). With regard to claim 1, Beers discloses, in Fig. 1 and paragraph [0053], 1.

With regard to feature [4c] of claim 1, each of Beers and Walters discloses that the cathode is denoted by 160, the emission layer is denoted by 135, and the ETL is denoted by 145 (Beers: Fig. 1, ¶ 53; Walters: Fig. 1, col. 7, lines 38-40 and col. 8, line 23). Walters discloses that the ETL 145 can be an n-doped material, e.g. Li-doped BPhen (Walters: col. 8, lines 23-32). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to make the ETL 145 of Beers from the n-doped material, Li-doped BPhen because Beers suggest using this n-doped material by incorporating Walter by reference for the materials of the OLED other than for the emissive layer 135 (Beers: ¶ 53). This is all of the limitations of claim 1. With regard to claims 3, 4, 8-13, and 20, Beers further discloses, 3. (Previously Presented) The organic light-emitting device of claim 2, wherein M1 is iridium, platinum, osmium, titanium, zirconium, hafnium, europium, terbium, thulium, or rhodium. 4. (Previously Presented) The organic light-emitting device of claim 2, wherein M1 is iridium, and a sum of n1 and n2 is 3, or M1 is platinum, and the sum of n1 and n2 is 2. 8. (Currently Amended) The organic light-emitting device of claim 2, wherein Ln2 is represented by at least one of Formulae 2A to 2C: PNG media_image8.png 306 242 media_image8.png Greyscale [i.e. in the ligand on the right side of Compound 3, above, CY5 is a pyridyl group, i.e. the claimed C1-C30 heterocyclic and CY6 is a phenyl group, i.e. a C5 to C30 carbocyclic with all R50 and R60 being hydrogen] 9. The organic light-emitting device of claim 1, wherein the emission layer 135 emits a red light, a green light, or a blue light [abstract]. 10. The organic light-emitting device of claim 1, wherein [1] the emission layer 135 further comprises a host and a dopant [¶¶ 40, 42-46, 91, 93-97], and [2] the dopant comprises the at least one organometallic compound [¶¶ 40, 91]. 11. The organic light-emitting device of claim 1, wherein the n-doped layer 145 comprises an electron transport compound [BPhen] and an n-dopant [Li] [supra]. 12. The organic light-emitting device of claim 11, wherein the electron transport compound comprises a cyano group, a π electron-deficient nitrogen-containing ring group, an electron transport moiety, or a combination thereof. 13. The organic light-emitting device of claim 11, wherein the n-dopant comprises a metal [i.e. Li]. 20. (Original) An electronic apparatus, comprising the organic light-emitting device of claim 1 [¶ 60, e.g. a display]. V.
