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)(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 1 is rejected under 35 U.S.C. 102(a)(2) as being anticipated by van der Heijden et al., hereinafter called van der Heijden (US 20220416725 A1).
Regarding claim 1, van der Heijden (Fig. 2A) discloses a Doherty amplifier circuit comprising:
a carrier amplifier (see path 230) comprising one or more first amplifiers(driver stage205) ; and
a peaking amplifier (see path 250) comprising one or more second amplifiers (driver stage 305), wherein at least one amplifier of the first amplifiers or the second amplifiers comprises:
a transistor (transistor 244) that receives a radio frequency signal (RF input node 212) and that receives a changing bias voltage bias voltage control circuit 246 which provide bias voltage to the base terminal of transistor 244) or a changing bias current at a base or a gate of the transistor, and that outputs an amplified radio frequency signal from a collector or a drain of the transistor (collector of transistor 244), and
a feedback circuit (feedback circuit include capacitor 249) configured to provide a voltage or a current based on the amplified radio frequency signal to the base or the gate of the transistor (base of the transistor 244), or to an emitter or a source of the transistor.
Allowable Subject Matter
Claim 2-11 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.
