Appeal No. 2001-0594
Application No. 08/929,153
that the bus coupling the two integrated circuits have signal
lines including a bus clock, a data in signal line and a data out
signal line and that the signal lines, including the bus clock,
be inactive when the bus is placed in a reduced power consumption
state. Moreover, the existence of the wake-up event recited in
the preamble of the claim must be signaled “by changing at least
one signal line of the bus from a first voltage level to a second
voltage level while the bus clock is inactive, in response to the
wake-up event detected by the second integrated circuit.”
While the examiner points to Walsh, at column 29, lines 49-
56, and column 27, line 66 to column 28, line 2, for changing a
signal line of the bus from a first voltage to a second voltage
in response to a wake-up event recognized by the second
integrated circuit, our review of these portions of Walsh does
not comport with the examiner’s position.
These portions of Walsh relate to the six states of a state
machine shown in Figure 23. We find nothing therein, and the
examiner has not convincingly pointed to anything therein, that
relates to the bus 104 having a bus clock, and data in and data
out signal lines wherein the signal lines and the clock are
inactive when the bus is placed in a reduced power consumption
state and wherein the existence of a wake-up event is signaled
