DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
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.
Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yoon et al. (WO 2020/138867) (hereafter “Yoon”).
Regarding claims 1-20, Yoon teaches an electroluminescent device comprising an anode, a hole transporting layer, a blue light emitting layer, an electron transporting layer, and a cathode (paragraph [251]-[264]). Yoon teaches that the blue light emitting layer is composed of

, where that amount of

is 2% (paragraphs [78], [80], [110], [135], [251], and [264]).

are preferred compounds of the applicant and would meet the applicant’s claimed emission and absorption spectrum limitations. Yoon teaches the electroluminescent device can be used in a light apparatus comprising several pixels (plurality of electroluminescent devices) and the different pixels emits different color and one of the pixels can be the blue emitting device (paragraphs [5], [351], and [352], Fig. 5).
Regarding claim 20, the claim does not require Ar1, Ar2, and R to be a heteroaryl or fused heteroaryl group; therefore, the compounds of Yoon meet the applicant’s claimed invention.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Ikeda et al. (US 2012/0235561) teaches anthracene host materials that meet the applicant’s claimed formula and are used as hosts for use for blue light emitting layers.
Hatakeyama et al. (US 2018/0301629) teaches boron complexes for use as dopant materials in electroluminescent devices. The boron compounds meet the applicant’s claimed formula.
