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 & 9 are objected to because of the following informalities: In claim 1, line 4, the recitation of “non linear” should change to read as --- non-linear--. In claim 9, line 6, the recitation of “ Gate terminal” should change to read as ---gate terminal---. 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 9-11 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 9, line 8, the recitation of “only in and around the first voltage” is vague and indefinite because it can not determine what is meant by only in and around the first voltage, the reason being that neither specification nor the claims define what is meant by this terminology. Further clarification is needed. Claims 10 & 11 are rejected due to their dependency. Allowable Subject Matter Claims 1-8 are allowed. The following is an examiner’s statement of reasons for allowance: Upon conclusion of a comprehensive search of the pertinent prior art, the Office indicates that the claims are allowable. The prior art when taken alone, or, in combination, cannot be construed as reasonably teaching or suggesting all of the elements of the claimed invention as arranged, disposed, or provided in the manner as claimed by the Applicant. Added primarily for emphasis, the claim recitations “ a first set of offsets matching with the offset error characteristic over a second range of power supply voltages that are within the first range of power supply voltages” in claim 1 and “a first supply voltage range that is within and smaller than the wide range; measuring a first set of offsets corresponding to a first set of voltages in the first supply voltage range” in claim 6 are not found in the prior art of record. Claims 1-5 and 7-8 are allowable as being dependent of claims 1 & 6, respectively. 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. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 4,547,746 A, Erickson et al. discloses an amplifier circuit comprising amplifier 24 being connected to a variable voltage source 34 and wherein resistor 36 being connected between the variable voltage source and an amplifier 38 having input terminals and one input terminal connected a node between resistor 36 and voltage supply 34 and other input terminal connected to a node between amplifier 24 and the resistor 36.
