Office Action

§102 §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 . Election/Restrictions Newly submitted claims 15, 17, 18, 24, and 25 are directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: they read on unelected fig. 4 and not elected fig. 7 Since applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claims 15, 17, 18, 24, and 25 are withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added claims are readable upon the elected invention. Should applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention. 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 2 and 28 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. Regarding claim 2, it claims that the voltage regulation circuit includes a second integrator 102. However, parent claim 1 introduces "a circuit" that appears to have the same connections claimed as the second integrator of claim 2. Regarding claim 28, it is rejected since it depends on claim 2. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1, 2, and 6 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Entringer (US 2016/0011014). Regarding claim 1, fig. 3 of Entringer discloses a circuit, comprising: a voltage regulation circuit having a voltage output [e.g. output of amp3], a feedback input [e.g. from 3 via 11], and a reference input [e.g. Vref, Vrefh, Vrefl], the feedback input coupled to the voltage output, the voltage regulation circuit including: an integrator [15] having a first input, a second input, and an output, the first input of the integrator coupled to the feedback input, the second input of the integrator coupled to the reference input, and the output of the integrator coupled to the output of the voltage regulation; and a circuit [7] having an input coupled to the output of the integrator and an output coupled to the first input of the integrator, the circuit configurable to, responsive to the output of the integrator moving in a first direction, provide a signal at the first input of the integrator to cause the output of the integrator to move in a second direction opposite from the first direction (via negative feedback from 11). Regarding claim 2, fig. 3 of Entringer discloses wherein the integrator is a first integrator, the reference input is a first reference input, and the voltage regulation circuit includes a second integrator having a first input coupled to the feedback input, a second input coupled to a second reference input, and an output coupled to the first input of the first integrator. Regarding claim 6, fig. 3 of Entringer discloses a feedback circuit [3] having a first terminal coupled to the voltage output of the voltage regulation circuit, and a second terminal coupled to the feedback input of the voltage regulation circuit. Allowable Subject Matter Claims 11, 13, 14, 22, and 23 are allowed. Claims 7-9 and 27 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Response to Arguments Applicant’s arguments with respect to claim(s) 1 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
