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, 3, 4, 6, 7, 11 and 17-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by [Choi (Fig. 1); 10,911,002].
Regarding claims 1, 11 and 18, Choi discloses an amplifier circuit comprising an over voltage protection circuit (400, 500, 210, 220, R3), a power amplifier (Fig. 1) amplifying an input RF signal (IN) by receiving a bias current (Ibias1) from a bias circuit (210, R3) and the circuit comprising an input signal detector (400) detecting a magnitude of the input RF signal (IN), and a first transistor (Q1) receiving the magnitude of the input RF signal (IN) through a control terminal (base terminal of Q1) thereof and turned on based on the magnitude of the input RF signal (IN) to sink the current from a first node (11) of the bias circuit (210, R3).
Regarding claim 3, wherein the bias circuit (210, R3) comprises a second transistor (Q21) supplying the bias current (Ibias1), and the first node (11) is a control terminal (base terminal of Q21) of the second transistor (Q21).
Regarding claim 4, wherein the input signal detector (400) comprises a first resistor (resistor in 400) adjusting a turn on voltage level of the first transistor (Q1) based on the magnitude of the input RF signal (IN).
Regarding claims 6 and 17, wherein the magnitude of the input RF signal (IN) corresponds to an envelope of the input RF signal (IN).
Regarding claim 7, wherein the power amplifier (Fig. 1) comprises a power transistor (Q1, Q2) amplifying and outputting a voltage of the input RF signal (IN), and the bias circuit (210, R3) supplies the bias current (Ibias1) to the power transistor (Q1).
Regarding claim 19, Choi further comprising one or more bias circuits (210, 220, R3) configured to supply the one or more bias currents (Ibias1, Ibias2) and wherein the over voltage protection circuit (400, 500, 210, 220, R3) is further configured to sink the bias current (Ibias1) from the one or more bias circuits (210, 220, R3) to decrease the at least one (Ibias1) of the one or more bias currents (Ibias1, Ibias2).
Regarding claim 20, wherein the over voltage protection circuit (400, 500, 210, 220, R3) comprises a sink transistor (Q21) configured to turn on to decrease the at least one (Ibias1) of the one or more bias currents (Ibias1, Ibias2), and a resistor (R3) configured to adjust a turn on voltage of the sink transistor (Q21).
Allowable Subject Matter
Claims 2, 5, 8-10 and 12-16 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.
