In somewhat of a victory for Valve, a mutual agreement has been reached with Blizzard over the contested “DOTA” trademark. Blizzard were set to use the DOTA trademark as part of their upcoming game Blizzard DOTA and contested Valve’s trademark request. Instead, under the agreement, Blizzard’s new game will be titled Blizzard All-Stars allowing Valve to use the ‘DOTA’ trademark commercially.
Gabe was glad things were resolved saying “[Valve is] pleased that we could come to an agreement with Blizzard without drawing things out in a way that would benefit no one. We both want to focus on the things our fans care about, creating and shipping great games for our communities.”
Full press release below.
/EDIT: Joystiq has also come out to say that Dota 2's release is now in 2013. Here's the source.
