Appeal No. 95-1187
Application 08/024,495
"system power standby mode of operation"
22. Amano has nothing equivalent to Applicant's claim
limitation that the system power be off during the checking step.
The system power is on during Amano's code entry steps. (5:36-
45; Fig. 3.)
"immediately determining whether the
on-screen display is in a locked state"
23. As with Bonneau, the argument that Amano does not
immediately determine the lock state (Paper 25 at 8) is
unavailing. The PPC key can be broadly construed as part of the
code sequence. Consequently, the fact that the PPC key must be
pressed before the determination begins does not remove Amano
from the scope of claim 8.
storing the secret code, clearing the display,
and locking the system if it is unlocked
24. Amano is silent about whether the entered lock code is
stored. Nothing in Amano suggests a step equivalent to
Applicant's step of storing a new code if the system is not
locked.
determining whether the system is locked
25. As with Bonneau's system, Amano's system can be said to
be locked when any channel is locked within the broadest
permissible meaning of claim 8. Thus, Applicant's argument that
Amano's system is not locked (Paper 25 at 10) is not correct.
