COMIC LEGEND: A company sued Warners because The Dark Knight Rises used the name of their property as a fictional item.
One of the MacGuffins in The Dark Knight Rises is the "Clean Slate" software that Selina Kyle wants to get a hold of to wipe herself off the face of the Earth, electronically.
Well, as it turns out, there was a company that had a problem with that aspect of the hit film. From the Seventh Circuit, Fortres Grand Corp. v. Warner Bros. Entertainment, Inc....
The Seventh Circuit held for Warner Bros., as they determined that there was no way that anyone would be confused as to whether Warner Bros. was behind Fortres Grand's product.
Thanks to my buddy Loren for suggesting this one!
