Appeal No. 2000-2291
Application No. 08/777,721
agree with Appellant that “the purpose of generating audio
signals, musical sounds, tones or voices representative of
complex time varying audio signals or musical waveforms” would
not have taught or motivated one of ordinary skill in the art to
transmit as aural message stored in a voice mixer in Hayashi’s
apparatus.
Based on our analysis above, we find that the Examiner has
failed to set forth a prima facie case of obviousness because the
necessary teachings and suggestions for implementing synthesized
signals stored in the voice mixer of Van Buskirk as the aural
message corresponding to the operational state of the facsimile
apparatus of Hayashi, are not shown. Accordingly, we do not
sustain the 35 U.S.C. § 103 rejection of claim 1 over Hayashi and
Van Buskirk.
