Appeal No. 2002-0278
Application 08/797,674
Upon our review of Tan, we find that Tan fails to teach
a request activation queue for storing request information
until the rings are accessible; and a response activation
queue for storing response information until the memory
access controller is accessible; wherein the request
information is used to construct request data packets; and
the response information is used to construct request data
packets
as recited in Appellants’ claim 1. Furthermore, we fail to find
that Tan teaches
storing request information in a request queue until the
rings are accessible; and storing response information in a
response queue until the memory access controller is
accessible; monitoring system resources; constructing
request data packets from the request information when
system resources are available; and constructing response
data packets from the response information when system
resources are available
as recited in Appellants’ claim 24. In particular, we find that
Tan teaches a system that manages the transmit and received
packets data buffer associated with high layer communication
protocol. See column 8, lines 38 through 58, of Tan. Tan
further discloses that figure 2 illustrates eight access-class
transmit queues, one MAC-packet request queue and one non-MAC-
packet received queue. Tan further discloses that the queuing
structure is used in a data communication controller. See column
9, lines 33 through 56, of Tan. Upon our further review of Tan,
