Office Action

§102 §112
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 . Election of Species Applicant’s election without traverse of the following species in the reply filed on 24 July 2026 is acknowledged: PNG media_image1.png 281 352 media_image1.png Greyscale and PNG media_image2.png 202 377 media_image2.png Greyscale . Claim Objections Claims 2 and 6 are objected to because of the following informalities: some of the substituent subscript designations as well as single vs double bonds are not clearly distinguishable. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 is rejected as being vague and indefinite when it recites “provided that when R1 is each independently hydrogen or deuterium, at least one of Ar1 and Ar2 is a substituted or unsubstituted C2-60 heteroaryl containing one or more selected from the group consisting of N, O and S” (emphasis added); the scope of the protection sought is not clear, in part as there are seven of the substituents R1 and only one each of the substituents Ar1 and Ar2. Claim 1 fails to particularly point out and distinctly claim the compound of formula 1 contained in the claimed organic light emitting device. Claim 1 is rejected as being vague and indefinite when it recites “wherein the compound represented by Chemical Formula 1 optionally contains one or more deuteriums” (emphasis added); the scope of the protection sought is not clear, in part as claim 1 already recites that each of the seven R1‘s and each of the six R2‘s may be deuterium. Claim 1 fails to particularly point out and distinctly claim the compound of formula 1 contained in the claimed organic light emitting device. 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. Claims 1-10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lee et al. (Korean Patent No. KR-10-2020-0043269; for convenience, reference is made to the English language equivalent U.S. Patent Application Publication No. 2022/0123233). Lee et al. teaches an organic light emitting device comprising an anode, a cathode, and an emitting layer, characterized in that said emitting layer comprises a combination of a compound inclusive of the compound of the elected species 1-1, as generally represented therein by PNG media_image3.png 230 343 media_image3.png Greyscale ([0062], p. 9) with a compound inclusive of the compound of the elected species 2-1, as generally represented therein by PNG media_image4.png 212 343 media_image4.png Greyscale ([0042], p. 7). In fact, in addition to the claims therein, multiple examples therein expressly illustrate the organic light emitting device characterized by comprising an emitting layer containing their combination thereof. As shown in Table 2 ([0146], p. 79) PNG media_image5.png 196 417 media_image5.png Greyscale , the compound inclusive of the compound of the elected species 1-1 utilized in each of Device Examples 3 and 5, is represented therein by PNG media_image6.png 328 359 media_image6.png Greyscale , and the compound inclusive of the compound of the elected species 1-1 utilized in Device Example 5 is represented by PNG media_image7.png 322 312 media_image7.png Greyscale , and the compound inclusive of the compound of the elected species 2-1 utilized in each of Device Examples 3 and 4, is represented therein by PNG media_image8.png 343 423 media_image8.png Greyscale , and the compound inclusive of the compound of the elected species 2-1 utilized in Device Example 5 is represented by PNG media_image9.png 352 429 media_image9.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. 2024/0147853, which is the pre-grant publication corresponding to the present application.
