Appeal No. 2000-2091
Application 08/441,024
requests/commands from clients as the clients request services
from the server.
Appellant’s claim 1 recites a client/server system
wherein each client that downloads data from the server,
processes the data and returns the processed data back to the
server. The claimed server “supervises data in a memory unit
in the server” while the client writes the data to a memory
only when the client detects server break down. We find that
the server does not become a client and remains a server
during the period the client writes the processed data and
transfers the data back to the server, as soon as the client
confirms that the server is in operation. We also note that,
without any instructions or requests received from the server,
the data storing and transferring functions are performed by
the client to merely preserve the processed data during the
time the server is down. Thus, based on the established
distinctions between “client” and “server,” the transaction
processing control section of Kobayashi that carries out such
functions at the server side, is different from the claimed
data storing and transferring which is performed at the client
side.
