Was thinking of this after a conversation I had on a thread about dreams. Someone joked "I was dreaming of the events of The Matrix, then I was woken up by someone worried my dream was infringing the Wachowski's copyrights", and it turned into a whole train of thought in my mind, like violating IP law because you stole fire from Zeus which was his intellectual property.
Rape could be tried as a copyright violation, probably have better results in the courts. (A sad state of affairs)
The trademark on Grandma's Mac and Cheese (or other recipe of choice) would start fights at Thanksgiving.
