DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. The preliminary amendment dated February 10, 2023 is entered. Claims 1, 2, 11, and 12 were amended. Claims 1-13 are pending. Amendments to the specification and abstract are acknowledged. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b ) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the appl icant regards as his invention. Claim 13 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 13 recites the limitation “the organic material layer” (singular) while parent claim 12 , upon which claim 13 depends, specifically recites “one or more organic material layers” and “at least one of the organic material layers” . There is insufficient antecedent basis for “the organic material layer” limitation in claim 13. Clarification and/or correction is required. 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 1-13 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 2021/0098708 A1). Kim et al. teaches organic electroluminescent devices with compounds according to Formula 1 (see abstract): . In Formula 1, X1 to X4 may be CRa, L may be substituted or unsubstituted arylene of 6 to 30 carbon atoms or heteroarylene of 2 to 30 carbon atoms and n may be 1 or 2, Ar may be substituted or unsubstituted hydrocarbon of 6 to 30 carbon atoms or heterocyclic, and Ra may be hydrogen, deuterium, amine, alkyl, aryl, or substituted or unsubstituted heteroaryl among others (see par. 9). With respect to instant Formula 1 of claim 1 , Kim et al. Formula 1 corresponds to the instant “A” ring as oxazole ring. With respect to the presence of a group corresponding to instant R1, Kim et al. teaches a variable Ra may include a substituted amine or substituted heteroaryl (see par. 9). “ Heteroaryl ” is specifically taught to include triazine (see par. 67) and “ substituents ” are taught to include at least aryl or heteroaryl (see par. 56). With respect to claim 2 , the Kim et al. Formula 1 core structure (see abstract) corresponds to instant Chemical Formula 1-3. With respect to claim 3 , a corresponding instant L1 group is single bond when a substituted heteroaryl triazine or amine is selected as Kim et al. Ra (see par. 9 , 67 ). With respect to claim 4 , substituents on a substituted heteroaryl as Ra (see par. 9, 67) may be aryl such as phenyl (see par. 56, 62). With respect to claim 5 , Ra may be amine (see par. 9), which may include at least a diphenylamine group (see par. 68). With respect to claim 6 , if the triazine group is substituted with phenyl aryl corresponding L2 and L3 are single bond and if triazine group is substituted with biphenyl aryl a corresponding L2 and L3 may be considered to represent a phenyl of the corresponding biphenyl group. (see par, 9, 56, 62, 67). With respect to claim 7 , if a Kim et al. group Ra is the amine group, it may be diphenylenimine, which corresponds to instant L4 and L5 as single bond (see par. 9, 68). With respect to claim 8 , substituents on a substituted heteroaryl (triazine) as Ra (see par. 9, 67) may be aryl such as C6 phenyl (see par. 56, 62). With respect to claim 9 , Ra may be amine (see par. 9), which may include at least a diphenylamine group (see par. 68) corresponding to both of instant Ar3 and Ar4 as C6 phenyl. With respect to claim 10 , Kim et al. group Ar corresponds to instant R2 and Ar may be selected as aryl or heteroaryl (see par. 12) that may specifically include at least aryls phenyl, biphenyl, or naphthyl (see par. 62) or heteroaryls dibenzofuran or dibenzothiophene (see par. 67). With respect to above discussed groups of Kim et al. Formula 1, the definitions encompass groups within specific compounds of claim 11 . For instance with respect to at least the below reproduced compound of instant claim 11 (see instant application preliminary claim set bottom row, right, on bottom page number listed as “ 19 ”), Kim et al. Formula 1 corresponds where Ar is aryl phenyl, L is arylene phenylene, n is 1, X1 is CRa where Ra is heteroaryl triazine substituted with aryl phenyl s and each of X2 to X4 are CRa with the Ra as hydrogen (see par. 8, 9, 56-71 and above discussions of groups) : INSTANT COMPOUND included with in instant claim 11 . With respect to claims 12 and claim 13 , Kim et al. Formula 1 compounds are used in an emissive layer (i.e., “light emitting layer”) of a light emitting device between a first electrode and second electrode (see abstract). While Kim et al. does not appear to show a Formula 1 example compound the same as instant Formula 1, as discussed above, Kim et al. defines groups for Formula 1 compounds the same as required with in instant Formula 1 compounds. Given the teachings of the reference, it would have been obvious to one of ordinary skill in the art prior to the effective filing date of the instant invention to form defined Kim et al. Formula 1 compounds for light emitting devices as described above wherein the resultant compounds and devices using the compounds would also meet the limitations of the instant claims. One would expect to achieve functional compounds for use in operational light emitting devices within the disclosure of Kim et al. with a predictable result and a reasonable expectation of success. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: KR 20200128794 discloses compounds with heterocyclic cores of Formulas I or II where R1 group may be triazine groups (see abstract) : . The reference is considered relevant to the field of the endeavor.
