Office Action

§102 §112
CTNF 18/038,280 CTNF 70775 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 Claim 1 is objected to because of the following informalities: superfluous recitations including “[Chemical Formula 1]” and “[Chemical Formula 2]”. Appropriate correction is required. This may easily be rectified by deleting the aforementioned phrases. 07-29-01 AIA Claim s 2 and 8 are objected to because of the following informalities: some of the bonds, i.e., single versus double, therein the recited formulae are indistinguishable, and some of the substituents therein the recited formulae are not clearly decipherable . Appropriate correction is required. 07-29-01 AIA Claim s 3 and 4 are objected to because of the following informalities: each recites that “at least one R 1 is the substituent represented by Chemical Formula 2”, which is superfluous as it is recited in line 6 (counting the structural formula as one line) of claim 1 . Appropriate correction is required. Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claims 1-12 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. Amended claim 1 is rejected as being vague and indefinite when it recites “at least one R 1 is the substituent represented by Chemical Formula 2, and the rest are each independently”, ( emphasis added); the scope of the protection sought by is not clear, as the claim fails to particularly point out and distinctly claim the antecedent basis for “the rest”, i.e., “at least one R 1 is the substituent represented by Chemical Formula 2, and the remaining R 1 ‘s are each independently”. 07-06 AIA 15-10-15 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 07-07-aia AIA 07-07 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 – 07-08-aia AIA (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. 07-15 AIA Claim s 1, 3, 9,10, and 12 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Jeong et al. (U.S. Patent Application Publication No. 2020/0176679) . Jeong et al. teaches a compound, the corresponding use thereof said compound as a dopant in the light emitting layer of an organic light-emitting device, characterized in that said compound has a benzazaborino core and contains a benzofuranyl substituent, and is inclusive of the compound of the present formula 1, as generally represented therein by PNG media_image1.png 245 392 media_image1.png Greyscale (claim 1), and more specifically, as represented therein by either of the following compounds (claims 6): PNG media_image2.png 334 860 media_image2.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. 2024/0124495, which is the pre-grant publication corresponding to the present application; and the following, each of which teaches a benzazaborino core and a benzothiophenyl and/or benzofuranyl substituent: - U.S. Patent Application Publication No. 2024/0306504, U.S. Patent No. 12,540,145, U.S. Patent Application Publication No. 2024/0008364. Allowable Subject Matter Claims 2, 4, and 8 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, assuming arguendo that (a) the claims are rewritten to overcome the objections set forth in preceding paragraphs 2-4 in this Office action, and (b) claim 1 is rewritten or amended to overcome the rejection under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), 2nd paragraph, set forth in preceding paragraph 7 in this Office action. Claims 5-7 and 11 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. assuming arguendo that (a) the claim 1 is rewritten to overcome the objection set forth in preceding paragraph 2 in this Office action, and (b) claim 1 is rewritten or amended to overcome the rejection under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), 2nd paragraph, set forth in preceding paragraph 7 in this Office action.
