to communicate via the inherent video display output
and video display signals of Schultz (see, e.g.,
inherent to the use of a CRT display screen in
Schultz, col. 6, ll. 47-49) in order to increase the
input/output capacity of Schultz because
communicating via the video display output port and
signals frees any existing input-output ports and
parallel printer ports for other types of
communications.
The examiner assumes that Schultz's system inherently
includes a video display output and video display signals.
The phrase "video signal" generally is used in the context of
televisions and conventionally is defined at least as narrowly
as in the following dictionary definition presented by
appellants (Brief, page 11): "The signal containing all of the
visual
information together with blanking and synchronizing pulses."
Schultz discloses (column 7, lines 25-28) a "word processor or
text source" for generating a document to be printed or
displayed. Displaying text data requires at least a standard
display signal, as that provided to a CRT, but not the
synchronizing and blanking pulses of a video signal. Since
the examiner has pointed to nothing in the reference to
indicate that Schultz even contemplated use of a video signal,
nor to any extrinsic evidence that Schultz actually includes
