Appeal No. 2000-1944
Application 08/738,157
Dahl requires a visible display because it is communicating
manual signaling between human operators and, thus, applying the
display teachings of Dahl to the computer communication system of
Froehling is problematic absent some teaching or suggestion that
a visible display is necessary. The fact that Froehling could be
modified to add a visual display does not make such a
modification obvious absent some evidence of motivation to do so.
We conclude that the Examiner has failed to establish a prima
facie case of obviousness. Accordingly, the rejection of
claims 1-10 and 21-30 is reversed.
