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 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. Claims 1, 2, and 5 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wilson et al. (J. Chromatogr A. 2016, 1461, 107-119, cited on Applicants information disclosure statement, filed on 2/20/26). Wilson et al. teaches the compound PNG media_image1.png 212 206 media_image1.png Greyscale (page 22). As applied to formula 1 of claim 1, this compound has X equal to S and all Y1 through Y10 equal to CR3 with all R3 equal to hydrogen atoms. This compound also anticipates claim 2 which further limits optional embodiments where substituents are present. This compound also anticipates claim 5 since it anticipates all of the structural limitations of formula 1. Because of this, it would be expected that this compound would be capable of serving as an organic electroluminescent material. 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. Wilson et al. is not suggestive of compounds or devices which satisfy claims 3, 4, and 6-10. Conclusion Applicant's submission of an information disclosure statement under 37 CFR 1.97(c) with the timing fee set forth in 37 CFR 1.17(p) on 2/20/26 prompted the new ground of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 609.04(b). 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. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
