Swordmaker, you do have problems with reading comprehension. I said Xerox was pissed at Apple and so they sued Apple - you attempt to discredit my statement by posting evidence my statement was factually correct. Try reading the statement before you reply. I believe you claimed Apple licensed the GUI from Xerox - clearly you were wrong and that was my point. Thank you for providing supporting evidence for my point.
A judge also tossed out Apple's lawsuit against Microsoft
My point was Xerox believed Apple stole their technology - you claimed Apple licensed the Xerox GUI which was merely more make-it-up-as-you-go-alone MacMythology.
Again you are factually correct, but again you miss the larger picture. Apple gave Xerox tons of stock (IOW, paid them) to let its engineers look at and learn from the Xerox technology. You don't take money and let engineers learn from your technology without an implicit understanding that such technology may be used by those engineers in another project -- unless the guy who allowed the visit was a total idiot (something scarce at PARC)
So, no, there was no license. Yes, Xerox let Apple engineers learn from their work. Yes, Bill just looked at what he saw publicly and tried to copy.
