Or how about this one: Lexidata holds a patent on the "concept" of doing
solid modeling and rendering on a peripheral device, i.e. not the
host.  Raster Tech is fighting this one because of its Model 1/25.
This patent could be interpreted to include any terminal (or
workstation even) connected to a host computer (or simply more powerful 
computer, in the case of a workstation).
