Official DIII evidence Diablo 3 is already published for opposition as a sequel at the USPTO. The same was done for D1, D2, D2LOD, WOW, Burning Crusade, and the Wrath of the Lich King. The mark has been live since 2005. Blizzard published it for opposition in early 2007 and it is undergoing administrative setbacks (just like so many others). Starcraft: Ghost's mark is "Dead and Abandoned" BattleChat is awaiting opposition. I speculate BattleChat 1.0 being deployed in tandem with D3, but I haven't really looked very far into that yet.
