Hmm,

How would you explain Xerox suing Apple over this?

I can't find a mention of Apple licensing anything in the wikipedia article either:

Also this claims to debunk the story: http://books.google.pl/books?id=gzAEAAAAMBAJ&lpg=PA3&...

"Xerox did at one time owne stock in Apple, they were purchased as an investment"

(All this followed from the Wikipedia page, I'll admit)
