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 . Specification The disclosure is objected to because of the following informalities: In paragraph [0042], line 4, “range.” should be replaced with --range--. 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 7, 8, 10-18, and 19 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. Claims 1 and 19, the limitation “a first voltage determination unit that determines the supply voltage and a set voltage range” is unclear. The original specification discloses that the first voltage determination unit 200 determines whether or not the voltage supplied from the voltage supply unit 100 is within a set voltage range and the first voltage determination unit 200 compares the voltage supplied from the voltage supply unit 100 with the set voltage (see par. 0036]). Claims 8 and 10-18 are indefinite due to their dependencies upon claim 1. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Tabata (US 4,309,627) discloses a detecting circuit for a power source voltage. Chihara (US 4,037,399) discloses a battery potential detecting circuit. Allowable Subject Matter Claims 7, 8, 10-18, and 19 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.
