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 . Response to Amendment The amendment filed on 08/12/2026 is entered and acknowledged by the Examiner. Claims 2, 4, and 7 have been amended. Claims 1-10 are currently pending in the instant application. The rejection of claims 2, 4, and 7 under 35 U.S.C. 112 (b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite is withdrawn in view of Applicant’s amendment. The indicated allowability of claims 1, 3, 5, 6, and 8-10 is withdrawn in view of the new rejection below. Priority Receipt is acknowledged of certified copies of papers (CN 202311053496.X) required by 37 CFR 1.55. 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 1-10 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. In claim 1, at line 7, recites a limitation, in part, “washing the solution A with deionized water”. This limitation is rendered indefinite because it is uncleared how a solution can be washed with deionized water. Appropriate correction and/or clarification is required. Claims 2-10 depend from claim 1 and are indefinite based on their dependencies. Allowable Subject Matter Claim 1 (and dependent claims 2-10) would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
