Office Action

§102
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 . DETAILED ACTION 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 allowance or after an Office action under Ex Parte Quayle, 25 USPQ 74, 453 O.G. 213 (Comm'r Pat. 1935). 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, prosecution in this application has been reopened pursuant to 37 CFR 1.114. Applicant's submission filed on 9/16/25 has been entered. 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)(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. Claims 1, 2, and 5 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Zhang et al. (US 2022/0282091, cited on Applicants information disclosure statement, filed on 9/16/25). Zhang et al. teaches the compound PNG media_image1.png 84 100 media_image1.png Greyscale (FIG. 1). This compound anticipates Formula 1 of claim 1 with X equal to S, Y8 equal to CR3, R3 equal to methyl, and all other Y groups equal to CR3 with R3 equal to hydrogen. Claim 2 may also be rejected using this compound as claim 2 serves to further limit optional embodiments where the groups recited in claim 1 are substituted. The compound above may also be used to reject claim 5. Because the compound above anticipates Formula 1 of claim 1, it would be expected that such a compound would display electroluminescence as required by both claims 1 and 5. Allowable Subject Matter Claims 3, 4, and 6-10 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The structures taught by Zhang et al. are mutually exclusive from those of claims 3 and 4. Further, Zhang et al. is from a completely different field of endeavor from Applicants and does not teach or suggest the preparation of organic electroluminescent devices as required by claims 6-10.
