Appeal No. 96-2023
Application No. 08/139,642
In combining Davis with APA, the examiner states
[principal answer-page 5] “that an adaptive decoder could have
been used in the prior art disclosed by applicants on pages 2-
5 of the present application to enable a single channel or
line to be used to transmit signals with different formats”
[emphasis in the original]. With this much of the examiner’s
analysis, we agree. Since the prior art recognized that one
could manage different formats by segregating transmitters of
different formats onto separate communication lines and Davis
taught the desirability of using a single detector to process
one of a plurality of transmitted signals, clearly, it would
have been obvious to enable a single channel to be used to
transmit signals with different formats.
The problem with the examiner’s analysis is that the
instant claims require more than the mere use of a single
channel for transmitting signals with different formats. Each
of the independent claims requires, in some form, the
production of a “sequence of a plurality of different
handshake signals having respectively different data formats
on a single input line” and that sequence of handshake signals
is sent until an answer is received in a data format
