Appeal No. 2002-1041
Application 08/866,402
(Paper No. 15), although there is no express discussion that it
showed a depressed key.
Volk discloses a visual representation of plurality of keys,
where control buttons 102, 103 in Fig. 3A are equivalent to
"keys." Volk discloses enlarging the visual representation of
the selected button (key) by putting a focus ring 105 around the
control items (Fig. 3A; col. 20, lines 2-24). Appellants do not
contest that Volk shows enlarging the visual representation. 2
Appellants argue that "the characteristic of displaying a
depressed key is not found [in Volk]" (Br10). However, Volk

displaying a depressed key. For example, the calculator
accessory in Windows NT (introduced in 1994) changes the visual
representation of a key on keypad to indicate a depressed key and
the exit/minimize/maximize buttons on the upper right hand corner
of the windows in Windows NT are shown depressed when selected.
Similarly, in WordPerfect 6.1 (issued in 1995), which is being
used to write this opinion, the buttons on the toolbar and
powerbar are displayed as depressed when selected.
