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 05/26/2026 overcomes all previous grounds of rejection and/or objection. Upon further review, new grounds of rejection were observed. This Office action is NON-FINAL. 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 5-18,20 and 30 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. It is not clear from the way claim 5 is written which of the listed components are comprised within the “composition”, and which are not in the composition but merely in the kit. For example, the anion exchanger could be in the composition, or just in the kit. It is advised that the components within the composition be enumerated (e.g. i), ii), iii), etc.), and the components not within the composition be introduced with “wherein the kit further comprises”. As all claims depend ultimately from claim 5, they are rejected for the same reason. Claim 20 is 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 20 recites “wherein the pH is…”. It is unclear to what this refers. If it refers to the “composition”, claim 20 should recite “wherein the pH of the composition is…”. In any event, further clarification is required.
