Office Action

§112
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. Drawings 3. The drawings are objected to because the "FIG. 1" label of the single viewing cannot appear in the sheet. See 37 CFR 1.84(u)(1). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification 4. The disclosure is objected to because of the following informalities: The Specification refers to the single view drawing as "FIG. 1.” However, all instances of "FIG. 1" should be replaced by "The FIGURE" or "the FIGURE" as numbered abbreviations are not allowed as there is only one single viewing. See 37 CFR 1.84(u)(1). Furthermore, the “FIG. 1” label in the Drawings should be deleted. Appropriate correction is required. 5. The disclosure is objected to because of the following informalities: The Specification filed 05/24/23 recites the structures of compounds 1-54 on the following pages: 4-7 which are all graphically unclear due to their low resolutions and small sizes; the individual atoms are barely legible. Furthermore, the text of the reactants shown in the reaction schemes on the following pages: 9, 11, 13, and 16 are too small. They all need to be replaced by structures which are clearly legible and of sufficient sizes, with all bonds and atoms (if applicable) that are clearly drawn (i.e., with solid lines). Appropriate correction is required. Claim Objections 6. Claims 7 and 15 are objected to because of the following informalities: Claim 7, which the other claim is dependent upon, fails to conclude with a period (the period needs to be placed outside the boxes). Appropriate correction is required. Claim Rejections - 35 USC § 112 7. 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. 8. Claims 3, 11, and 17 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 3, which the other claims are dependent upon, recites “o-aryl” and “o-heteroaryl” derivatives which renders the exact scope of the claim indefinite due to the undefined nature of “o-aryl” and “o-heteroaryl” groups. Clarification is required. Allowable Subject Matter 9. Claims 1, 2, 4-6, 8-10, 12-14, 16, and 18-20 are allowed. Furthermore, Claims 7 and 15 are currently objected to due to minor informalities but would be allowable if amended to overcome the objection as set forth above. Examiner’s Note: The Office has relied on national phase publication US 2021/0332290 A1 as the English equivalent of WIPO publication WO 2020/048253 A1 (herein referred to as “Peng et al.”). Unless otherwise noted, all figure, page, and paragraph numbers referenced herein refer to numbers found in the national phase publication. The closest prior art is provided by Peng et al. (WO 2020/048253 A1), which discloses complexes of the following form: PNG media_image1.png 550 436 media_image1.png Greyscale ([0010]); an embodiment is disclosed: PNG media_image2.png 350 442 media_image2.png Greyscale (page 5). However, it is the position of the Office that neither Peng et al. singly nor in further combination with any other prior art discloses any of the compounds as recited in the claims, particularly in regards to the nature of the carbazolyl group (comprising A0) of Applicant’s formula (I). Conclusion 10. Any inquiry concerning this communication or earlier communications from the examiner should be directed to JAY L YANG whose telephone number is (571)270-1137.
