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 Objections Claims 1-2, 10-15 are objected to because of the following informalities: For claims 1-2, 10 and 15, those claims recite “modular particle valve”, “particle valve”, and “modular valve”. It looks like those terms refer to the same structure. It is recommended that applicant use the same term for the same structure. In claim 11-14, the limitation “the instructions cause the computing device” needs to be changed to “the instruction, when executed cause by the computing device, the computing device”. Appropriate correction is required. 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 1-15 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 1 recites the limitation "the valve modules" in line 18. There is insufficient antecedent basis for this limitation in the claim. Examiner recommend applicant to amend this limitation to (and for examining purpose, examiner interprets this limitation is) “the plurality of valve modules”. NOTE: there are other place throughout entire claim set that have the same issues. Claim 10 recites “the modular valves”. There is insufficient antecedent basis for this limitation in the claim. Examiner recommend applicant to amend this limitation to (and for examining purpose, examiner interprets this limitation is) “the plurality of valve modules”. Allowable Subject Matter Claims 1-15 would be allowable if rewritten or amended 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.
