Office Action

§103 §112
DETAILED ACTION The present Office Action is responsive to the Amendment received on November 18, 2025. Preliminary Remark Claims 11-24 are new. Election/Restrictions Claims 1-8 remain withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on April 15, 2025. Claim Objections The objection made to claims 9 and 10 for reasons discussed in the Office Action mailed on September 4, 2025 is withdrawn in view of the Amendment received on November 18, 2025. Claim Rejections - 35 USC § 112 The rejection of claims 9 and 10 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point out and distinctly claim the subject matter, made in the Office Action mailed on September 4, 2025 is withdrawn in view of the Amendment received on November 18, 2025 and reconsideration. Rejection – New Grounds, Necessitated by Amendment 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 9-24 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. Claims 9 and 10 are indefinite for reciting the phrase, “Pt(II) complex comprising a bidentate group and a N-heterocyclic group comprising a hetero substituted imidazolium group and a halogen group”. It is unclear whether the N-heterocyclic group is comprising both the hetero substituted imidazolium group and the halogen group; or that the N-heterocyclic group is hetero substituted imidazolium group only, and the Pt(II) comprises this and a separate halogen group. For the purpose of prosecution, the latter assumption is made. Claims 12-24 are indefinite by way of their dependency on claims 9 or 10. Claim Rejections - 35 USC § 103 The rejection of claims 9 and 10 under 35 U.S.C. 103 as being unpatentable over Fung et al. (Nature Communications, February 2016, pages 1-9) in view of Solomatina et al. (Dalton Tran., 2015, vol. 44, pages 7152-7162), made in the Office Action mailed on September 4, 2025 is withdrawn in view of the claim amendment and arguments presented in the Amendment received on November 18, 2025. Conclusion No claims are allowed. Claims are free of prior art. The claims directed to non-elected invention (i.e., product) should be canceled. 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.
