Does IBM have a patent for the hardware version of it?
- acveilleux 11y agoThis is yet another invention from PARC that was marketed/finished outside of Xerox. The patent was initially filed in 1990 and granted in 1996. So it should have expired in 2013. It seems to be owned by Lexmark (which was owned by IBM.)
