Appeal No. 96-0734
Application No. 08/056,739
through 1111, and for the polling station 101 to collect the
messages from the stations.
Citta is concerned with peak upstream loading in a two-
way cable television (CATV) contention system. During
upstream retransmissions by subscriber terminals 11 to CATV
headend 12, a transmission window time (Figure 5) is a
function of the upstream message traffic load. In other
words, the number of attempts by subscribers 11 to retransmit
to the CATV headend 12 is directly related to the upstream
transmission window size time (Figure 5; column 7, lines 23
through 37).
Based upon the foregoing, we agree with appellant (Brief,
page 13) that "[t]he patents, when viewed alone or in
combination, fail to suggest any incentive for a person of
ordinary skill in the art to modify the data terminals to
transmit an unsuccessful attempt count to the terminal mapping
means or to modify the terminal mapping means to remap based
on an unsuccessful attempt count instead of the time it takes
to collect all available messages during a probing cycle."
In summary, the obviousness rejection of claims 5 through
8, 10, 26 and 30 through 36 is reversed.
