I don't think there is anything else left, most, if not all of the patents have expired.
There has got to be something other than the patents -- everything that has a copyright on it, for example?
Well, maybe the revolutionary "Commodore Amiga" machines are not going to happen after all. What kind of company announces that "Commodore USA" has the exclusive marketing rights to Amiga then puts the Amiga trademark itself up for sale? (Yes, Amiga Inc. is that kind of company.)
