Appeal No. 2003-1632
Application 09/173,991
unlike claim 40, claim 70 requires that the notification device
associated with the vehicle be activated when the communications
monitoring determines that it is improperly occurring. Appel-
lants’ arguments with respect to independent claim 73 correspond
to those of independent claim 70 (Brief, page 11).
As best expressed in the Reply Brief, we agree with
appellants’ general observation initially that the vehicle
classification data comprising part of the “commit” message as
relied upon by the examiner at column 3 of Chaum does not form
any reasonable version of a so-called password to the extent
recited in claim 40, and not necessarily within the ambit of the
monitoring communication of claim 70. Still, we sustain the
rejection because according to the examiner’s initial positions,
the reference teaches at the middle of column 5 its reliance
upon a so-called public key cryptography or RSA system. This
conventional system in the art relies upon the use of a so-called
private key which is known only to the user but the remaining
portions of the cryptography system are public information. It
is this private key that may provide a basis of the broadly
“associated” password associated with the tag computer limitation
of representative claim 40 on appeal.
