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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-8 are rejected under 35 U.S.C. 103 as being unpatentable over Hatakeyama et al (WO 2020040298) (Hatakeyama).
In reference to claims 1-3 and 6-8, Hatakeyama teaches an organic electroluminescent device including a host compound (e.g. the compounds below, in box) [057]), a thermally activated delayed phosphor (e.g. compound DCN3 below [060]) and a compound having a boron atom (e.g. the Boron compound below [0130]) as components of the light emitting layer between an anode and a cathode (Hatakeyama [004] to [005]).

Hatakeyama further teaches that the use of these materials as taught realizes a spectrum with good halftone width and a good color, high external quantum efficiency, improved roll-off and long life (Hatakeyam [036]).
Given that Hatakeyama discloses the device configuration that encompasses the presently claimed device, including a light emitting layer comprising the components above, it therefore would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application, to use device configuration, which is both disclosed by Hatakeyama and encompassed within the scope of the present claims and thereby arrive at the claimed invention.
For Claim 1: DCN3 reads on a first host wherein d is 1, R1 a carbazole, f is 1, and Ar1 is a substituted phenyl, the host compound reads on formula 2 wherein each of X1 is N, each of Ar2 is a substituted phenyl, and the boron compound reads on a formula (4) wherein DEFG and H are ach benzene, each Y1 is B, one of X2 is O and each other of X2 is N-Ar3 and Ar3 is phenyl.
For Claim 2: Reads on substituted phenyl.
For Claim 3: Reads on formula 5.
For Claim 6: Reads on formula 8.
For Claim 7-8: Reads on 0.05 (per the instant specification same as compound 4-121).
In reference to claims 1-5 and 7-8, Hatakeyama teaches an organic electroluminescent device including a host compound (e.g. the compound below, in box [057]), a thermally activated delayed phosphor (e.g. compound DCN3 below [060]) and a compound having a boron atom (e.g. the Boron compound below [0130]) as components of the light emitting layer between an anode and a cathode (Hatakeyama [004] to [005]).
