The Chicago Cubs are suing “rooftop operators” who charge people to sit on rooftops overlooking the friendly confines of Wrigleys Field.  This was the fact pattern in my law school copyright exam. Seriously.  The article mentions that there’s a copyright claim which might refer to the fact that the rooftop guys apparently have TV sets up there (because the baseball game itself isn’t a fixed work).  This is one of those rare and elusive unjust enrichment fact patterns in IP law.  More coverage here and here.
