Appeal No. 97-3256
Application 08/280,012
Audebert was cited by appellant as evidence of the
background of the invention. Audebert teaches a similar system
of communication between a central computer (server) and remote
terminal (device 1). The critical time periods in Audebert are
defined as follows:
1) T1 is the time at which a question is
asked;
2) T2 is the time at which a player has
entered an answer into the device 1;
3) T3 is the deadline for the player to
answer the particular question;
4) T4 is the time at which the answer to
the question is revealed to the player;
5) T5 is the time at which the server
requests the answer from the player’s
device 1;
6) T’5 is the time at which the device 1
receives the request for the answer from
the server (which is essentially the
same as T5); and
7) T6 is the time at which the server
enters the answers from the player;
[see column 11, line 63 to column 12, line 10]. Audebert teaches
the computation of parameters *T and *T . The first parameterint ref
is defined as the time period T’5 - T2, and the second parameter
is defined as T5 - T3 [see Figure 6]. These two values are
compared to ensure that a specific relationship exists between
them.
Each of independent claims 1, 6, 7 and 15 recites at
least the time periods T1, T2 and T5 which correspond to the same
