DETAILED ACTION
Claim Rejections - 35 USC § 112
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claim 3 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 3 is inconsistent as it depends on claim 1 and recites compounds, such as H84 and H85, wherein the moiety corresponding to the divalent group L is a direct bond, which is not allowed in claim 1. Further, some of the compounds in claim 3 have missing chemical bonds, e.g., EH10, or are illegible, e.g., PH68.
Allowable Subject Matter
Claims 1 and 4-11 are allowed.
Claim 3 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: The features of claim 1 are not disclosed or suggested anywhere. Related OLED’s wherein the moiety corresponding to the divalent group L of the chemical formula 1 is a direct bond are known as explained previously. Another relevant prior art is CN 112279844 A to Qian et al., which discloses an OLED comprising a plurality of organic material layers, including a light-emitting layer, disposed between two electrodes, wherein the light-emitting layer comprises the following compound as a host material,

(see compound 82 on page 6 on the original document). While this compound has the moiety corresponding to the divalent group L similar to formula L-1, it differs from the compound of formula 1, which does not allow L to connect to A at R1, R2 or R3.
Conclusion
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
