Bonneau teaches at least one lock key within the meaning of the
claim.
"system power standby mode of operation"
12. Applicant defines "stand-by power" as "the power
consumption while the chip is not performing any read or write
operation." (Paper 25 at 5 (citing New IEEE Standard Dictionary
of Electrical and Electronic Terms (5th ed.).) According to
Applicant, this describes his "power stand-by mode of operation".
(Paper 25 at 5.) Standby power for an unspecified chip, however,
does not correlate to the claimed system power standby.
13. The specification does not describe a "system power
standby mode". The closest description relates to the system's
main power status. (Paper 1 at 7.) The specification discloses
a main program loop that runs whether the system power is on or
off. The lock-function is only executed if the main system power
is off (i.e., in standby status). Thus, we construe "checking
. . . during a system power standby mode" (claim 8) to mean
running the key-checking function while the main system power is
off. Bonneau discloses no equivalent requirement for starting1
1 The fact that the power to the overall system is off
does not mean that no power is available to the remote control or
the "micom". By analogy, the power button on a standard
television remote control communicates with a detector in the
television that must receive some power even though the overall
