Appeal No. 1998-2612
Application 08/478,289
distortion sound effects circuit with its input coupled to the
clean output, and the output distortion circuit is proportionally
mixed with the clean output. The examiner finds that it would
have been obvious to the artisan to incorporate the effect-mix
variable device of Moog into the admitted prior art system
[answer, pages 3-4].
Appellant argues that there is no teaching or suggestion
to include the mixing circuitry of Moog into the admitted prior
art because the admitted prior art already includes the mixing
circuitry for blending affected signal with unaffected signal to
allow a user to precisely select to what degree the outboard
accessory device affects the signal. Appellant asserts that the
addition of mixing circuitry to the admitted prior art would be
superfluous and redundant [brief, pages 5-7].
The examiner responds that the proposed modification of
the admitted prior art is to only incorporate the mixing
circuitry as taught by Moog, not the whole outboard accessory
device as disclosed in Moog so that there would be no redundant
mixing circuitry after the modification [answer, page 6].
Appellant reiterates that the addition of mixing circuitry to the
admitted prior art is still redundant and superfluous [reply
brief].
