selected, the communication between terminal 2 and second
storage 7 is via the second transmission line. Yamada further
teaches that identical data is copied to storage devices so
that any terminal can access the same information independent
of the selected storage and the corresponding line.
We disagree with the Examiner that duplicate information
could be transmitted simultaneously over the first and the
second transmission lines of Yamada’s data processing system
as recited in Appellant’s claim 24. Yamada is concerned with
duplicate information contained in two storage devices where
each operates as a backup for the other rather than sending
duplicate information to the same terminal. More
specifically, Yamada in col. 2, lines 63 through 68, discloses
that the terminals are grouped into those using the first
storage and others using the second storage during normal
transmission. However, in col. 3,
lines 6 through 12, Yamada further adds that identical data is
stored in both storage devices which provide same information
to each terminal. Therefore, Yamada’s system does not
simultaneously connect each terminal to both storage devices,
