Following the revelation of Valve's plans for a Defense of the Ancients game and their recent trademark on DOTA comes word on PC Gamer that Steve "Guinsoo" Feak and Steve "Pendragon" Mescon, who participated in DOTA development before working on the DOTA-like League of Legends at Riot Games, are not pleased about this trademark. They explain that in order to keep DOTA in the hands of the community, they have filed their own trademark registration, so we will have to see how this all plays out. Here's word on the TM competition: "The situation is not as simple as a single person having total ownership over the name. But now we are exploring options to protect the DotA name. We [Dota-Allstars, LL--the company run by Pendragon] have filed for the “Defense of the Ancients” trademark to protect the work that dozens of authors have invested to create the game and on behalf of the millions of DotA players all over the world. If we were to obtain the trademark, we would keep the game and the DotA name freely available to the mod community. That way the game can continue to be worked on and enjoyed by the independent community. We want to ensure that the DotA name remains in the hands of the community and that it is free for all to use." Thanks joao.
