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 .
Double Patenting
Claim 1 is rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 10,804,867 and/or over claims 1-20 of U.S. Patent No. 11,545,947. Although the conflicting claims are not identical, they are not patentably distinct from each other because all of the limitations/features of the present claims are present in the patented claims.
Related Art
The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure.
Kim et al. U.S. 2004/0174212 discloses (please see Fig. 2 and related text for details) an analogous circuit having the same basic structure, namely an amplifier circuit including first and second amplifiers configured to amplify respective first and second portions of an input signal, each of the first and second amplifiers (amplifiers 60 and 70 of Fig. 2) including a cascode stage with input and output transistors arranged in a cascode configuration (assuming said generic amplifiers would be employed with cascode/output transistors in order to improve output impedance as widely-used in the field);
an envelope tracking bias circuit (20/30 of Fig. 2) coupled to the amplifier circuit, but lacks the claimed “ and configured to provide a bias signal to the output transistor of the cascode stage of at least one of the first and second amplifiers”; and
a supply circuit (battery or the like) configured to provide a non-envelope tracking supply voltage (VDD, peaking) to the output transistor of the cascode stage of the at least one of the first and second amplifiers.
Conclusion
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.”
