Controversies and legal disputes Blizzard Entertainment, Inc. v. Valve Corporation Shortly after Valve filed its trademark for "Dota" to secure the franchising rights for Dota 2, DotA-Allstars, LLC, run by former contributors to the game's predecessor, Defense of the Ancients, filed an opposing trademark in August 2010. DotA All-Stars, LLC was sold to Blizzard Entertainment in 2011. After the opposition was over-ruled in Valve's favor, Blizzard filed an opposition against Valve in November 2011, citing their license agreement with developers, as well as their ownership of DotA-Allstars, LLC. Blizzard conceded their case in May 2012, however, giving Valve undisputed commercial rights to Dota name, while Blizzard would rename their StarCraft II: Heart of the Swarm mod "Blizzard All-Stars", which would eventually become the stand-alone game, Heroes of the Storm.
