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 Objections Claims 2 and 12 are objected to because of the following informalities: In claims 2 and 12, the numbering sequence of the compounds is out of order. Appropriate correction is required. 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) 1-5, 11 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hatakeyama (WO 2022185897 A1). Regarding Claims 1-5, 11, Hatakeyama teaches a material represented by Int-v-10123 (page 261): PNG media_image1.png 160 238 media_image1.png Greyscale Int-v-10123 reads on applicants’ Formula 1 and 2 wherein Ar1 = H; Ar2-Ar6 = phenyl; Z = NR3, R3 = phenyl; X = NR4, R4 = heteroaromatic (amino substituted carbazole) (per claims 1-2, 11) Int-v-10123 reads on applicants’ Formula 12 wherein Ar1 = H; Ar2-Ar9 = phenyl; Z = NR3, R3 = phenyl; Y = NR7, R7 = heteroaromatic (amino substituted carbazole) (per claims 3-5). Allowable Subject Matter I Claims 6-10, 12 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 prior art of record fails to show the limitations of the above claims. The closest prior art as exemplified by Hatakeyama teaches a material represented by Int-v-10123 (page 261): PNG media_image1.png 160 238 media_image1.png Greyscale Int-v-10123 fails to show the required ring system of Formulas 13 and 14 of claims 6-10 or the compounds of claim 12. Allowable Subject Matter II The following is a statement of reasons for the indication of allowable subject matter as applicant claims the light emitting element of claim 13 and the display device of claim 20. A search of the prior art did not show the claimed invention. The closest prior art as exemplified by Hatakeyama teaches a material represented by Int-v-10123 (page 261): PNG media_image1.png 160 238 media_image1.png Greyscale Int-v-10123 while reading applicants’ Formula 1 is taught by Hatakeyama as an intermediate in route to a final product which is used in an OLED as shown below: PNG media_image2.png 182 608 media_image2.png Greyscale From the above reaction scheme (page 261) it can clearly be seen the Int-v-10123 is not the final product used in the OLED as required by independent claims 13 and 20. The final product used by Hatakeyama in OLEDs has a different parent ring system than applicants’ Formula 1. Hatakeyama fails to teach, suggest or to offer any guidance to render obvious using intermediate in an OLED or display device as required by independent claims 13 and 20. Claims 13-20 allowed.
