Application 08/174,215
Claims 4, 8, and 9
Appellants argue (Br11) that claim 4 recites "a
keyboard having a plurality of unmodified keys," a keyboard
controller which "generate scan code data responsive to
keyswitch signals generated by active keys," and that in the
first (pointer) mode the keyboard controller responds to
"said key switch signals" to transmit mouse data instead of
scan code data. Thus, Appellants argue that claim 4 recites
converting normal scan codes generated from conventional
keys into mouse data and distinguishes over Franz which uses
a specially configured multipurpose keyswitch (such as the
J key) which has direction sensors or other direction
sensing devices in addition to the normal switching devices.
"Thus, [in Franz] additional connections and special
circuitry are required, and additional processing must be
performed within the computer in order to accommodate this
method of emulating mouse data (see Col. 10, lines 1-14)."
(Br6.)
The Examiner admits that Franz does not disclose
