Now that I looked deeper into the patent on this story, this looks as if it might be a rehashing of old news from last year... not a new lawsuit filing.
“methods and systems for accessing one or more computer files via a graphical icon, wherein the graphical icon includes an image of a selected portion or portions of one or more computer files.”
That's exactly what my 1993 source tree of XV did. I don't know how long it had been incorporated into the source.
How do these guys get off using the name Cygnus anyway? That's the software company that is now merged into RedHat and maintains GCC and friends.
Bad news all around. Those guys have a stolen name and a patent that clearly has prior art. Unless this is the XV guy (and that work was Open Source), they do not have a leg to stand on.
