Appeal No. 2003-0258
Application 09/684,138
error amplifiers necessarily have a class A output stage is not
convincing.
For the above reasons we find that the examiner has not
carried the burden of establishing a prima facie case of
anticipation of the circuit claimed in the appellant’s claim 5.
Accordingly, we reverse the rejection of this claim.
Claims 6-9
The examiner does not provide any reasoning as to why using
in Rincon-Mora’s circuit an amplifier having a class A output
stage would have been prima facie obviousness to one of ordinary
skill in the art (answer, page 4). Consequently, we reverse the
rejection of claims 6-9.
