display controller would have been an obvious expedient as it is
a standard in the art to provide a VGA resolution since it is
well-known in a display system for providing a high quality color
display to a user (for example, see the discussion by Berry)."
The examiner's obviousness conclusion is without merit and
his rationale is misplaced.
The appellant is not claiming simply a VGA controller for
displaying VGA resolution display data. Rather, the invention's
apparent novelty is directed to the selection of a portion of
high resolution VGA display data based on addressed display data
and to display the selected portion on a display device of
"lower" resolution.
Independent apparatus claim 1 requires a frame buffer memory
means for storing a full resolution VGA image, a display means
having a resolution "less" than the resolution of the frame
buffer memory means for providing a display, and VGA controller
means for transferring display data in the frame buffer memory
means to the lower resolution display means. Claim 1 further
recites an address translate logic means for generating an
appropriate start address for updating the display means.
Corresponding steps are recited in independent process claim 3.
The claimed invention requires actual display of selected data on
