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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 06/23/2026 has been entered.
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.
Claim(s) 1-8, 11, 15-25 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by WO 2019009052 A1. US 20210167288 A1 is being relied upon as a direct English translation.

2-442 reads on applicants’ Formula I, I-0, IC wherein R1-RIV, RVI-RVIII = H; RV = phenyl substituted with a phenyl (per claims 1-4, 6-8).
RV = phenyl substituted with Ra = phenyl in Formula IIc (per claim 5).
Regarding Claim 11, 15-25, Hatakeyama teaches an OLED comprising: a pair of electrodes composed of a positive electrode and a negative electrode; and a light emitting layer disposed between the pair of electrodes and comprising the material for a light emitting layer (paragraph 37). The light emitting layer contains 2-442 as a dopant (emitter) along with a host. The dopant and the host can be pre-mixed and applied by deposition to form the layer (paragraphs 189-191) (per claims 11, 15-25).
