90's
The Apple suit against was entirely a Steve Jobs Ego driven suit & had it been successful, simply would have been Apple shooting itself in the foot.
I was working in SV at the time with a lot of friends working at high levels at both Apple as well as Xerox PARC. Xerox sat back and watched it play out in the courts on Apple's dime, as they knew that if Apple won their case that the Windows GUI "copied" the Lisa/Mac GUI and it was protected IP, that would have made themselves mincemeat as Xerox would have then gone after Apple for the Lisa/Mac GUI "copying" the Xerox Dynabook/Alto GUI based on Apple establishing the legal precedent & it was already quite public that the Lisa/Mac GUI came about after (and whose development was motivated by) Jobs saw a demo of the Dynabook/Alto GUI on a visit to Xerox PARC. Since Apple lost, no point in Xerox going after Apple.
