Office Action

§102
DETAILED ACTION 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, 4-6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chemical Abstract Compound: RN 391208-94-9. Regarding Claims 1, 4-6, RN 391208-94-9 : PNG media_image1.png 616 700 media_image1.png Greyscale RN 391208-94-9 reads on applicants’ applicants’ Formula 1 wherein X2 = n; X1 = C; R1 and R2 = H (per claims 1, 6); R = H (per claim 5) RN 391208-94-9 reads on applicants’ applicants’ Formula 4-2 wherein X12 = N; X11 = C; R1 and R2 = H (per claim 4). Allowable Subject Matter I Claims 2-3 and 7are 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 prior art of record fails to show: Formulas 1-1 and 1-2 (per claim 2) Z1 and Z2 (per claim 3) Compounds (per claim 7) Allowable Subject Matter II The following is an examiner’s statement of reasons for allowance as applicant claims the device of claim 8 A search of the prior art fails to teach the invention of claim 8. The closest prior art is Chemical Abstract Compound: RN 391208-94-9 which reads on applicants’ Formulas 1 and 4-2 but is not used in an OLED as required by independent claim 8. Claims 8-13 allowed. Conclusion Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Any inquiry concerning this communication or earlier communications from the examiner should be directed to GREGORY D CLARK whose telephone number is (571)270-7087.
