Appeal No. 95-1187
Application 08/024,495
the locking process from a system-power-off state. Thus, Bonneau
does not anticipate the claimed invention.
Displaying prompts and the key code on the screen
14. Bonneau displays two kinds of prompts for entry of a
security code: a blank screen (8:22-24) and a blinking screen
(7:50-53). Bonneau displays the blank screen during security-
code entry so the code cannot be observed. Applicant, however,
discloses acts of prompting for each digit of the code
independently and of displaying each digit as it is entered.
(Paper 1 at 8-11; Fig. 4. ) Thus, Bonneau's display step is not2
equivalent to the claimed display step.
"immediately determining whether the
on-screen display is in a locked state"
15. Applicant argues that Bonneau's determination is not
immediate because one must press the enter key before the
determination is made. (Paper 25 at 9.) The enter key, however,
is within the range of equivalents for key code inputs (i.e., the
enter key is the last digit of the code) when claim 8 is broadly
construed -- as it must be during prosecution. Thus, Bonneau's
television is off.
2 Figure 4 shows six displays entitled "LOOK SET". The
Korean priority document entitles the displays "LOCK SET", which
makes more sense in context. (Korean patent application number
88-18099, Fig. 3.)
