Earlier this year, Twentieth Century Fox registered a trademark for the word "Gotham" for;

Entertainment services in the nature of a television series featuring drama; providing on-line information in the field of television and video entertainment featuring drama via the Internet; entertainment services in the nature of non-downloadable videos and images featuring television shows transmitted via the Internet and wireless communication networks; on-line journals, namely, blogs featuring personal opinions in the field of general interest and drama; entertainment amusement park and theme park services; entertainment services in the nature of live musical, comedy and dramatic performances

Little bit cheeky. But there you go. Then Fox and Warners came to… some kind of deal over the future of the Batman TV series and its licensing. Now that trademark has been abandoned by Fox. And now Warners subsidiary DC Comics has registered the trademark Gotham for;

Entertainment services in the nature of live-action, comedy, drama, animated and/or reality television programs; production of live-action comedy, drama, animated and/or reality television programs. Downloadable live-action, comedy, drama, animated and reality television series; audio tapes, audio-video tapes, audio video cassettes, audio video discs, and digital versatile discs featuring music, comedy, drama, action, adventure, and/or animation.

You know, if there was a TV series set in the pre-Batman days of Bruce Wayne concerning the five families of organised crime, or some kind of Gotham PD show, calling it Gotham wouldn't be a bad idea…
