Which giant company has the rights to the fan-created, community-promoted word "Dota?" That's up to the courts now. Blizzard has filed a Notice of Opposition with the US Patent and Trademark Office, seeking to block Valve's registration of the word. The word has been used exclusively in reference to a (mod of a) Blizzard game, the document explains. "By virtue of that use, the DOTA mark has become firmly associated in the mind of consumers with Blizzard, including to signify a highly popular scenario or variant of one of Blizzard's best-selling computer games, Warcraft III."

Valve, the document goes on to claim, hasn't used the word for anything yet. There's also a lot of history of Warcraft III, which is a really strange thing to read in a legal document. The case is in discovery now, with pretrial procedures taking place throughout this year and into next. We hope this court proceeding doesn't delay either of the games, as those companies are quite capable of delaying their games on their own.
