=== Blizzard Entertainment, Inc. v. Valve Corporation ===
Shortly after [[Valve Corporation|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.<ref>{{cite magazine |last=Augustine |first=Josh |url=https://www.pcgamer.com/riot-games-dev-counter-files-dota-trademark/ |title=Riot Games' dev counter-files "DotA" trademark |date=August 17, 2010 |access-date=August 19, 2011 |magazine=[[PC Gamer]] |url-status=live |archive-url=https://web.archive.org/web/20130203103306/http://www.pcgamer.com/2010/08/17/riot-games-dev-counter-files-dota-trademark/ |archive-date=February 3, 2013}}</ref> 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.<ref>{{cite web |url=https://kotaku.com/blizzard-and-valve-go-to-war-over-dota-name-5883938 |title=Blizzard and Valve go to War Over DOTA Name |last=Plunkett |first=Luke |date=February 10, 2012 |website=Kotaku |url-status=live |archive-url=https://web.archive.org/web/20120211081846/http://kotaku.com/5883938/blizzard-is-suing-valve |archive-date=February 11, 2012}}</ref> 

An agreement was reached between Blizzard and Valve in May 2012 giving Valve undisputed commercial rights to the "DotA" trademark, notably for [[Dota 2]], while retaining rights for Blizzard to use the name in a noncommercial manner for its community "with regard to player-created maps for Warcraft III and StarCraft II". As part of the agreement Blizzard also renamed a custom map they had originally developed for ''[[StarCraft II: Wings of Liberty]]'' from "Blizzard DOTA" to "Blizzard All-Stars" which would eventually become the stand-alone game, ''[[Heroes of the Storm]]''.<ref>{{cite magazine |last=Reilly |first=Jim |url=https://www.gameinformer.com/b/news/archive/2012/05/11/valve-blizzard-reach-dota-trademark-agreement.aspx |title=Valve, Blizzard Reach DOTA Trademark Agreement |date=May 11, 2012 |access-date=May 23, 2012 |magazine=[[Game Informer]] |url-status=live |archive-url=https://web.archive.org/web/20120724090129/http://www.gameinformer.com/b/news/archive/2012/05/11/valve-blizzard-reach-dota-trademark-agreement.aspx |archive-date=July 24, 2012}}</ref>
