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 . Election/Restrictions Applicant’s election without traverse of Group II in the reply filed on 6/8/26 is acknowledged.

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 6-14 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. To Claim 1, since Claim 6 depends on Claim 1, the feature “RDE OER” should be spelled out and not abbreviated. To Claim 6, line 5, “dispersing the molten mixture” lacks antecedent basis. It is suggested to add the following to i) of Claim 6 “. . . precursor together to form a molten mixture; . . . “. To Claim 7, lines 3, “dispersing the molten mixture” lacks antecedent basis. It is suggested to add the following to i) of Claim 7 “. . . precursor together to form a molten mixture; . . . “. To Claim 8, lines 2-3, use of the word “preferably” are not definite. To Claim 9, lines 2-3, use of the word “preferably” are not definite. To Claim 11, line 2, use of the word “preferably” are not definite. To Claim 12, line 2, use of the word “preferably” are not definite. Allowable Subject Matter As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with. See 37 CFR 1.111(b) and MPEP § 707.07(a). The following is an examiner’s statement of reasons for allowance: Pang (CN 113477939). Pang describes combining a black sponge noble metal with H2O2 and then heating the mixture (see pages 2-3, sections 6 and 7). Peng does not then disperse the molten mixture in water. 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.
