John,
NO, the XOR cursor is the method of drawing the cursor…you XOR the
background to turn off pixels that are on, and turn on pixels that are off
(reverse video it). It is must useful with a block cursor that sits ontop of
other text.
Not knowing what the patent states…I can only presume it applys to
any cursor type device (which may or may not include a mouse cursor) that is
drawn onscreen via an XOR of the screen area.
And Commodore certainly uses those.
