Appeal No. 1999-0006
Application No. 08/470,970
the claimed invention except for the use of an application-
layer uniform interface protocol to provide communication
between a host computer and a network printer. To address
this deficiency, the Examiner turns to DeHart which, as
interpreted by the Examiner, discloses “ . . . computer
programming to allow application-layer communications in a
computer environment independent of the system on which the
program is running . . . ” (final Office action, page 3). In
the Examiner’s view, the skilled artisan would have been
motivated and found it obvious to include a uniform interface
protocol as taught by DeHart in the system of Davidson “ . . .
in order to provide a uniform protocol for interfacing between
computers using network service protocols/ports and a
printer.” (Id.)
