Office Action

§103
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 . 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. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 01/21/26 has been entered. Response to Amendment The objection to Claim 24 as set forth in the Final Rejection filed 10/22/25 is overcome by the Applicant’s amendments. The objection to Claim 25 as set forth in the Final Rejection filed 10/22/25 is overcome by the Applicant’s amendments. The rejection of Claim 24 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 as set forth in the Final Rejection filed 10/22/25 is overcome by the Applicant’s amendments. The rejection of Claim 25 under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends as set forth in the Final Rejection filed 10/22/25 is overcome by the Applicant’s amendments. The rejection of Claim 22 under 35 U.S.C. 103 as being unpatentable over Kawamura et al. (US 2016/0172601 A1 as set forth in the Final Rejection filed 10/22/25 is overcome by the cancellation of the claim. The rejection of Claims 19, 20, and 26-28 under 35 U.S.C. 103 as being unpatentable over Kawamura et al. (US 2016/0172601 A1 as set forth in the Final Rejection filed 10/22/25 is overcome by the Applicant’s amendments. Specification The disclosure is objected to because of the following informalities: The Specification filed 03/07/25 recites the structures on the following pages: 7, 22, 24 (Chemical Formula 11 only), 25-31, and 55 which are all graphically unclear due to their low resolutions and/or small size; they are barely legible. They need to be replaced by structures which are clearly legible, with all bonds and atoms that are clearly drawn (i.e., solid lines) and of sufficient size. Appropriate correction is required. Claim Objections 11. Claims 19, 20, and 24-30 are objected to because of the following informalities: Claim 19, which the other claims are dependent upon, recites that “in Chemical Formula 7, Sub1 and/or Sub2 is selected from the group consisting of deuterium, a halogen group . . . “; this portion of the claim needs to be replaced by the following: “in Chemical Formula 7, Sub1 and2 are, independently of each other, . Appropriate correction is required. Allowable Subject Matter 12. Claims 19, 20, and 24-30 are currently objected to due to minor informalities but would be allowable if amended to overcome the objection as set forth above. The closest prior at is provided by Kawamura et al. (US 2016/0172601 A1), which discloses inventive first compounds encompassed by the following formula: PNG media_image1.png 42 380 media_image1.png Greyscale ([0020]) where A = acceptor moiety, B = donor moiety, and L = linking group such as a substituted or unsubstituted aromatic hydrocarbon group having 6-30 ring carbon atoms ([0021]). An embodiment is disclosed: PNG media_image2.png 366 458 media_image2.png Greyscale (page 14). However, it is the position of the Office that neither Kawamura et al. singly nor in further combination with any other prior art discloses any of the compounds as recited in the claim, particularly in regards to the nature of the substituents connected to the triazine group. Response to Arguments 13. Applicant’s arguments on pages 18-21 with respect to the deficiencies of the previously cited prior art have been considered and are persuasive view of the newly amended claims. Hence, the rejection has been withdrawn. Conclusion 14.
