Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Status Claims 1-4, 9-11, 15-19, and 21-28 are under examination Claims 5-8, 12-14, and 20 are canceled 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 allowance or after an Office action under Ex Parte Quayle, 25 USPQ 74, 453 O.G. 213 (Comm'r Pat. 1935). 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, prosecution in this application has been reopened pursuant to 37 CFR 1.114. Applicant's submission filed on 07/10/2026 has been entered. Upon further search and consideration, the following 112(b) rejections are made to claim 9 and 11. Claim Rejections - 35 USC § 112 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 and 11 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 9 discloses a metal is at least one of a list including P (Phosphorus). Claim 11 discloses an organometallic compound with a formula MaRbXc where M is at least one of a list including P (Phosphorus). However, phosphorus is not a metal. It is unclear how phosphorus forms a metal or an organometallic compound. Allowable Subject Matter Claims 1-4, 10, 15-19, and 21-28 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Claims 1-4, 10, 15-19, and 21-28 are allowed for the reasons indicated in the office action filed 05/26/2026.
