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 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 1-12 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. The claims are confusing because when m is zero, the ligand is optional. Without the ligand present, the scope of the claims completely changes. As the ligand appears to be an essential component of the metal complex claimed, a value of m=0 is not understood. Also, when p and r are both zero, as allowed by the claims, M and L alone appear to be incapable of forming a metal complex. Claims 3, 8, and 11 are “use of” claims, and so are indefinite. Any inquiry concerning this communication or earlier communications from the examiner should be directed to CHARLES I BOYER whose telephone number is (571)272-1311.
