[citation][nom]balister[/nom]Learn your history Ossie: Xerox tried to sue Apple, but statue of limitation had expired and the court system slapped down Apple as well (saying you can't copyright a general look, only a specific look). Likewise, Apple had offered the preferred stock to the Xerox board members (not Xerox corp) before they got to look at PARC.[/citation]
You mix it up... Xerox' case was dismissed as having no merit, by statute (not statue
) of limitation period expiration. The case didn't got any further.
The apple vs. m$ case was about windblow$ 2.0 (and later 3.0), and was dismissed because m$ licensed earlier parts of the GUI from apple for windblow$ 1.0 (in exchange for m$ supporting the mac with further office releases), and the court considered this license was also extended to next versions, due to apple neglecting to explicitly limit it to windblow$ 1.0. The ruling was practically a sidestep from the matter of copyright infringement, the court not intending to set a legal precedent.
If you like wikipedia so much, read the whole sentence: "Xerox had invested in Apple (ie, Apple had given Xerox Board members stock in exchange for access to the research performed at PARC)..." nitpicking semantics...
While apple's IPO was in December '80, the visit at PARC was in '79, so practically it was only a promise at that moment, Jobs had nothing to "give" away. Both parties seemed to be satisfied with the deal, as Xerox didn't sue Apple when the Mac was released, but "suddenly remembered" the issue 5 years later... when some greedy execs smelled blood.
