Blizzard doesn’t want Valve a trademark on Dota requests. Dota, or Defense of the Ancients, is a modification for Blizzards rts-game Warcraft 3. Both developers are working on the successor of the Action Real-Time Strategy mod.
Valve began in 2010 with the procedure for requesting a trademark on the word Dota, reports Kotaku. Blizzard showed not happy with the request, but the group took no further action. Some time ago, the company has, however, made a formal complaint against the request of Valve, as was recently discovered.

In the application form requires Valve to the right to the trade names Dota, DOTA, Defense of the Ancients and DotA. Neither Blizzard, nor the modgemeenschap has ever had a similar trademark applied for.
The first release of Dota was a mod of Warcraft 3: Reign of Chaos. Since then, many derivatives have been developed. The most popular is DotA Allstars. Due to the enormous popularity of the games is Dota a subgenre of rts games become.
