Appeal No. 2001-0594
Application No. 08/929,153
Accordingly, we will not sustain the rejection of claims 12-
19 under 35 U.S.C. 102(e).
Finally, we turn to independent claim 25. This claim also
requires a communication of the existence of a wake-up event
detected by the second integrated circuit to the first integrated
circuit but does so by changing a second unidirectional data line
from a first to a second voltage level while the remaining signal
lines, including the clock line, are maintained in the power
savings mode. Therefore, the bus clock is not in an operating
mode at this time. The clock is then restarted “in response to
the changing of second unidirectional data line from the first to
the second voltage.”
We agree with appellant that Walsh does not teach using one
of the signal lines of bus 104 to indicate a wake-up event while
the clock line on bus 104 is in a power savings mode and then
restarting the clock in response to the wake-up indication.
Further there are no unidirectional data lines indicated in bus
104 by Walsh. The examiner’s rejection indicates that Walsh
teaches such unidirectional data lines but the examiner never
specifically identifies such lines and we are unaware of such
unidirectional lines in Walsh. Further, in response to
