Appeal No. 95-4815
Application No. 08/065,387
cause a video controller to actuate pixels on a monitor 38.
When the graphic is a thin, straight vertical line, the
artisan would have recognized that a column of pixels is to be
actuated.
On the other hand, claim 9 is not so broad as the subject
matter of claim 8 in that the former requires that the means
for receiving the data words also distribute those words into
VRAM such that the consecutive bytes written by the processor
actuate pixels in a single column. Therefore, the language of
claim 9 would appear to require that the data words be
distributed in a VRAM in a particular manner so as to achieve
the particular result of pixel actuation in a single column
while claim 8, in contrast, only requires receiving data words
and, based on those words, causing the actuation of a column
of pixels in no particular manner. While Diepstraten is
clearly capable of actuating a column of pixels based on data
words from the
processor, there is no suggestion in Diepstraten that that
actuation comes about through any particular distribution of
the data words in VRAM 30.
