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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. (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 1-3, 5, 6, 8-15, 17, 19, and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kim et al. (U.S. Patent No. 9,978,955). Kim et al. teaches a nitrogen-containing compound, the corresponding use thereof said nitrogen-containing compound in a light emitting element, wherein said element comprises a first electrode, a second electrode on the first electrode, and an emission layer comprises a nitrogen-containing compound there between said first electrode and second electrode, characterized in that said nitrogen-containing compound is inclusive of the nitrogen-containing compound of the present formula 1, as generally represented therein by PNG media_image1.png 244 331 media_image1.png Greyscale (column 26, line 1), said nitrogen-containing compound also encompassing the more specific formula 1-2 recited in claim 2 as well as formula 1-2B recited in claim 3, as represented therein by PNG media_image2.png 237 417 media_image2.png Greyscale (claim 16). In fact, the aforementioned specific compound is utilized in Examples 1-5 through 1-8 (column 175, line 23+). Claims 1-3, 5, 6, 8-15, 17, 19, and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wagner et al. (“Triazine Based Bipolar Host Materials for Blue Phosphorescent OLEDs”, 13 August 2013, Chem. Mater., 25, 3758). Wagner et al. teaches a nitrogen-containing compound, the corresponding use thereof said nitrogen-containing compound in a light emitting element, wherein said element comprises a first electrode, a second electrode on the first electrode, and an emission layer there between said first electrode and second electrode, characterized in that nitrogen-containing compound is inclusive of the nitrogen-containing compound of the present formula 1 as well as the more specific formulae 1-2, as represented therein by PNG media_image3.png 173 283 media_image3.png Greyscale and PNG media_image4.png 170 276 media_image4.png Greyscale . Claims 1-3, 5, 6, 8-15, 17, 19, and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Rudnick et al. (“The influence of torsion on excimer formation in bipolar host materials for blue phosphorescent OLEDs”, 7 June 2016, J.Chem.Phys., 144, 21406). Rudnick et al. teaches a nitrogen-containing compound, the corresponding use thereof said nitrogen-containing compound in a light emitting element, wherein said element comprises a first electrode, a second electrode on the first electrode, and an emission layer there between said first electrode and second electrode, characterized in that nitrogen-containing compound is inclusive of the nitrogen-containing compound of the present formula 1 as well as the more specific formulae 1-2, as represented therein by PNG media_image5.png 317 213 media_image5.png Greyscale and PNG media_image6.png 313 210 media_image6.png Greyscale . Claims 1-3, 5, 6, 8-15, 17, 19, and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Strohriegel et al. (“Novel host materials for blue phosphorescent OLEDs, Proceedings of SPIE, Vol. 8829, 882906). Strohriegel et al. teaches a nitrogen-containing compound, the corresponding use thereof said nitrogen-containing compound in a light emitting element, wherein said element comprises a first electrode, a second electrode on the first electrode, and an emission layer there between said first electrode and second electrode, characterized in that nitrogen-containing compound is inclusive of the nitrogen-containing compound of the present formula 1 as well as the more specific formulae 1-2, as generally represented therein by PNG media_image7.png 214 297 media_image7.png Greyscale . Prior Art The following prior art made of record and not relied upon is considered pertinent to applicant’s disclosure: U.S. Patent Application Publication No. 2024/0155941, which is the pre-grant publication corresponding to the present application; U.S. Patent Application Publication No. 2024/0164208, which is pertinent to a pyrimidine compound having attached thereto a single carbazole group; U.S. Patent No. 8,227,798 which is pertinent to a pyrimidine compound having attached thereto two carbazole groups, but is missing the biphenyl group as in the present formula 1. Allowable Subject Matter Claims 4, 7, 16, and 18 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.
