For years, Lucasfilm not only allowed, but actively encouraged Star Wars fan fiction. Similarly, Paramount encouraged Star Trek fan fiction. But now that Disney owns the rights to Star Wars, what would happen if someone wrote a crossover fan fiction story in which Luke Skywalker got transported to the Star Trek universe (from a galaxy far, far, away) and assimilated by the Star Trek villains known as the Borg? Would Luke retain his Force powers? Would the other Borg acquire Force powers? Would the author of the story be sued for copyright infringement?
We don't know the answers to the first two questions, but the third one is examined in Ken's article on Gray Works, which was recently published in the Journal of Intellectual Property Law. Read it here and find out how little anyone knows about this emerging area of copyright law.
And may long life and prosperity be with you.
