Column 5, lines 53-56 thus describes an interrupt request generated by shared
memory device 20 to a receive OS. The interrupt request is shown as element 77 in
Figure 7, and described in detail at column 7, lines 13 through 60 of the reference. The
interrupt occurs prior to transfer of data in memory 50, depicted in Figure 8. The
procedure is thus related to the dynamic allocation of shared memory, prior to the actual
message transfer between programs residing in different subsystems.
The rejection thus does not account for, at least, "computer readable program
means for transmitting a first signal to said provider computer that said consumer
computer is ready to receive and extract data from said shared memory." The identified
section of Yamaoka that is deemed to disclose the feature refers to communication from
the provider computer to the consumer computer, rather than in the reverse direction. At
least paragraph "iv" of claim 13 is also not met by Yamaoka, since there is a requirement
of action by the provider computer "after receipt of said first signal."
Anticipation requires the presence in a single prior art reference disclosure of each
and every element of the claimed invention, arranged as in the claim. Lindemann
Maschinenfabrik GmbH v. American Hoist & Derrick Co., 730 F.2d 1452, 1458, 221
USPQ 481, 485 (Fed. Cir. 1984). While Yamaoka may disclose elements similar to those
set forth in instant claim 13, the reference does not disclose the claimed features including
the signals that are sent and received between the provider and consumer computer in
