Office Action

§102
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 Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1 and 4 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fujiwara et al. (9,041,473), hereinafter called FUJIWARA. Regarding claim 1, FUJIWARA (Figs. 1, 6 and 8) discloses a circuit comprising: see Fig. 6, a detection component (15) having a detection end connected with a signal input end (IN) of a power amplifier (CA1), and configured to detect an input signal of the signal input end; a control component/circuit (9) connected with the detection component, and configured to output a control signal (cont) according to the input signal detected by the detection component; and a variable resistor (Rv1 of Figs. 1 or 8) connected with an output end of the control component, and configured to change resistance linked to the power amplifier according to the control signal, to compensate a phase of the power amplifier. Regarding claim 4, wherein the control signal (cont) is inherently negatively or positively correlated with the input signal. Note, the control signal (cont) is based on detected input signal, which the control the variable resistor as claimed invention and thus should have similar function. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by SU et al. (CN 113746438 A), hereafter called SU. Regarding claim 1, SU (Fig. 3) discloses a circuit comprising: a detection component (102) having a detection end connected with a signal input end via capacitor (201) of a power amplifier (no label), and configured to detect an input signal of the signal input end; a control component/circuit (103) connected with the detection component, and configured to output a control signal according to the input signal detected by the detection component; and a variable resistor (101) connected with an output end of the control component, and configured to change resistance linked to the power amplifier according to the control signal, to compensate a phase of the power amplifier. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Cai et al. (CN 112187192 A), hereafter called CAI. Regarding claim 1, CAI (Fig. 1) discloses a circuit comprising: a detection component (R1 and C1) having a detection end connected with a signal input end (RFin) of a power amplifier (PA), and configured to detect an input signal of the signal input end; a control component/circuit (M1 and R2) connected with the detection component, and configured to output a control signal via node (A) according to the input signal detected by the detection component; and a variable resistor (M2) connected with an output end of the control component, and configured to change resistance linked to the power amplifier according to the control signal, to compensate a phase of the power amplifier. Allowable Subject Matter Claims 2, 3 and 5-20 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. The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 2, 3, 5-7 and 10-20, prior art(s) does not disclose the control component has a first path and a second path, the control component switches to the first path and outputs a first control signal under a first condition, to perform first phase compensation on the power amplifier through the variable resistor, the control component switches to the second path and outputs a second control signal under a second condition, to perform second phase compensation on the power amplifier through the variable resistor, the first phase compensation is in a direction opposite to the second phase compensation. Regarding claim 8, prior art(s) does not disclose the control component has a first path comprising: a second current mirror having an input end connected with the detection component; a control circuit having a first end connected with an output end of the second current mirror and a second end connected with the variable resistor, to output a first control signal; a clamping circuit connected with the first end of the control circuit; and a power supply connected with the second end of the control circuit. Regarding claim 9, prior art(s) does not disclose the control component has a second path comprising: a control circuit having a second end connected with the detection component and a first end connected with the variable resistor, to output a second control signal; and a voltage control circuit having one end connected with the first end of the control circuit and another end grounded. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The additional reference(s) cited in PTO-892 show further analogous prior art circuitry.
