As close as we're going to get to Harry Potter meeting fantasy baseball

The Recruitment of Harry Potter. Given the recent fantasy baseball case's reliance on the idea that baseball stats are facts in the world, would it be legitimate to have a fantasy Quidditch league? And, now that I think of it, does the capitalization imply that Quidditch is a trademark, like Bertie Bott's Every Flavor Beans? Quidditch sure seems like a generic term. Maybe we need an article on Harry Potter and the Fundamentals of IP.
