Appeal No. 1999-0890
Application 07/575,096
Although the Examiner noted10 that he performed the
requisite 35 U.S.C. § 112, sixth paragraph analysis wherever
means-plus-function language appears in the claim, no specific
analysis is provided for this claim or this limitation in any
other claim. Appellants have not addressed this issue.
The specific function associated with the means limitation
is controlling a display of a receipt for a transaction on said
display of said write input device and for printing a copy of the
receipt including a signature.
The only structure disclosed11 for implementing the
aforesaid function of the "controller means” is a personal
computer with a graphics adapter and an adapter board for
additional serial ports for communications.
The means-plus-function clause is construed as limited to
the corresponding structure disclosed in the specification and
equivalents thereof. As admitted by the Examiner, the Dunkley
controller is not capable of performing the claimed function and
thus cannot be corresponding structure or an equivalent thereof.
