Can I take your product and modify it so as to reach new audiences?  CleanFlicks “edits” out what it deems to be inappropriate material (i.e. sex and violence) and then rents or sells the edited version.  It argues that the First Amendment gives them the right to do so and filed a declaratory judgement action.  The movie companies very likely believe that the judge will not have to make new law to find that this is text-book  trademark and copyright infringement.
