answer at pages 3-4.) We disagree with the examiner’s analysis and conclusion about
near baseband and baseband. From our review of the teachings of Strolle, we find that
Strolle specifically desires the use of the passband signal for the demodulator and the
adaptive equalizer since Strolle teaches at col. 11, lines 45-50, and col. 12, lines 17-18,
that the adaptive equalizer operates in the passband signal prior to the recovery of the
carrier signal and the remainder of the circuit operates at baseband. From these
teachings, we find no support for the examiner’s position. With respect to the teachings
of Werner, while Werner appears to teach the basic filter configuration, we find no
express teaching or suggestion that the system is useful for VSB signals or that it
operates at baseband. Therefore, we find that the examiner has not established an
initial prima facie case of obviousness of the claimed invention, and we cannot sustain
the rejection of independent claims 1, 6, 11, 13, and 16 and their dependent claims.
