Office Action

§112
CTFR 17/500,277 CTFR 93490 DETAILED ACTION 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. 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. Response to Amendment The amendment of 03/17/2026 has been entered. Claims 1, 22, 36, and 41 are amended due to the applicant's amendment. Claims 1-3, 5, 7-10, 12-13, 20-22, 33, 35-37, and 39-42 are pending. The objection to the specification as set forth in the previous Office action is withdrawn . The objection to the claims 1 and 22 as set forth in the previous Office action is overcome due the applicant's amendment. The objections are withdrawn . The rejection of claims 1-3, 5, 7-10, 12-13, 20-22, 33, 35-37, and 39-42 under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA), first paragraph, as failing to comply with the written description requirement as set forth in the previous Office action is overcome due to the applicant's amendment. The rejection is withdrawn . The rejection of claims 1-3, 5, 7-10, 12-13, 20-21, 33, 35-37, and 39-42 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 previous Office action is overcome due to the applicant's amendment. The rejection is withdrawn . The rejection of claims 1-3, 5, 7, 10, 12-13, 20, 22, 33, and 41 under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Kim et al. US-20190081252-A1 as set forth in the previous Office action is overcome due to the applicant's amendment. The rejection is withdrawn . The rejection of claims 1-3, 5, 7-9, 13, and 40 under 35 U.S.C. 102(a)(1) as being anticipated by Abe et al. JP-63019293-A as set forth in the previous Office action is overcome due to the applicant's amendment. The rejection is withdrawn . However, as outlined below, new grounds of rejection have been made under 35 U.S.C. 112(b). Response to Arguments The applicant’s arguments on pages 13-14 of the reply dated 03/17/2026 with respect to the objection to the specification and the rejection of claims 1-3, 5, 7-10, 12-13, 20-22, 33, 35-37, and 39-42 under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA), first paragraph, as failing to comply with the written description requirement as set forth in the previous Office Action have been fully considered and are persuasive with respect to the typographical error. The objection and the rejection have each been withdrawn . Claim Objections 07-29-01 AIA Claim 36 is objected to because of the following informalities: it is suggested that "Cr" be changed to "CR" for ease of reading . 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 Claim 20 is 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 . Regarding claim 20 , the claim recites the compound has a structure selected from the group consisting of Formula 1 to Formula 14, wherein Formula 3 has the structure PNG media_image1.png 224 348 media_image1.png Greyscale . Claim 20 depends from claim 1 ; however, it does not appear the Formula 13 meets the claimed limitations of the compound of claim 1 because it does not appear to meet one of provisos (i) to (iii). For purposes of examination, the claim will be interpreted such that the compound of claim 1 may not have the structure of Formula 13. Allowable Subject Matter 12-151-07 AIA 07-97 12-51-07 Claim s 1-3, 5, 7-10, 12-13, 21-22, 33, 35-37, and 39-42 are allowed. 13-03 AIA The following is an examiner’s statement of reasons for allowance: The closest prior art, exemplified by Lee et al. US-20190074458-A1, teaches an organic light-emitting device comprising a first electrode, a second electrode, an organic layer disposed between the first electrode and the second electrode comprising a tetradentate organometallic compound of a general Formula 1 PNG media_image2.png 167 172 media_image2.png Greyscale as a dopant (¶ [0009] and [0038]-[0044]) and Lee discloses examples including compound 56 PNG media_image3.png 259 336 media_image3.png Greyscale (page 45). However, the prior art as exemplified by Lee does not teach a compound of the claimed Formula 1 meeting each of the provisos recited in, and at least one of conditions (i) to (iii) recited in claims 1 and 22 or wherein the compound is one of those listed in claim 21 . For example, the above compound of Lee does not meet the proviso: PNG media_image4.png 60 808 media_image4.png Greyscale Further, the prior art does not provide a reason to modify the compounds of Lee to arrive at a compound of claimed Formula 1 meeting each of the provisos recited in, and at least one of conditions (i) to (iii) recited in claims 1 and 22 or wherein the compound is one of those listed in claim 21 with a reasonable expectation of success . Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion 07-40 AIA Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL . See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
