here is the history of GUI...
http://en.wikipedia.org/wiki/History_of_the_GUI
obviously, Doug Engelbart from Stanford Uni is da inventor of mouse and GUI... but Xerox is da first to apply those into computer OS... I think Xerox has da patent for their ALTO... but not da mouse nor da GUI... however... I wud say da modern use of mouse and GUI are da patent of Xerox (or Apple wud have paid da patent fee to Dr. Engelbart instead of Xerox)... so therez definitely connection between Xerox and mouse-GUI... they are not only a photocopier company... like tat?
