In the early 80s, after watching SW Rip Offs appear across the globe, i think something happened but can't find any stories of Lucasfilm cases online? (I thought i remember reading about them going after the Brazilian SW, but now i can't find that link)
Thinking about it some more, i'm probably mixing up the copyright infringement case Lucasfilm brought against the makers of Battlestar Galactica.
As already mentioned the Phantom Edit draws tons of media attention to the concept of fan edits.
Lucasfilm's spoiler policy conflicts with websites, T'Bone's "http://starwarz.com/tbone" has several editorials on the battles.
Lucasfilm endorses the parody segment of fan film culture.
Lucasfilm through a DMCA Cease & Desist, got the l337 RotS trailer removed:

The MPAA successfully prosecuted the leak of Revenge of the Sith.
Lots of creative projects here at the OT.com and beyond seem to have been made and distributed without any "legal entaglements".
