Last year, it was revealed that Blizzard had filed a notice of opposition against Valve with regards to the Dota trademarks. For a couple of months, the situation remained uncertain, but Blizzard have just announced that an agreement has been reached by both parties. According to this settlement, Valve will be allowed to use the Dota trademarks commercially, while Blizzard will maintain non-commercial use of the Dota trademarks. A win-win… mostly. Interestingly, as part of this agreement, Blizzard will change the name of their upcoming Action RTS game, from “Blizzard DOTA” to “Blizzard All-Stars“, a title which they say “ultimately better reflects the design of our game”.

Apparently, both Valve and Blizzard will have no further comment on the terms of the settlement beyond this press release, which is, ultimately, understandable. Good to hear that two awesome development studios (with a great focus on the PC community to boot) remain bros after all. After all, you know what they say: bros before… trademark disputes. Or at least I think that’s how it went.

[UPDATE: In their article on their subject, Joystiq intriguingly noted that Dota 2 is set to release... in 2013. Not sure if it's legitimate or just a typo, but it is worth bringing up. Credit to Smash of ValveTime for the discovery.]

Almost 10 years ago, Valve was involved in a turbulent, and controversial legal showdown with their then-publisher, Vivendi, regarding their bizarre and near-hostile practices (illegally distributing Valve games to Asian cyber cafes, withholding game royalties from Valve, purposely delaying CS: Condition Zero). Valve was victorious, although Activision Blizzard would later refuse to continue settlement payments to Valve.

Then, when Dota 2 was first revealed, and when Valve first filed for the trademark “DOTA”, Riot Games, the creators of the Action RTS title League of Legends (and the company that former Dota caretaker Steve “Guinsoo” Feak currently finds himself in the employ of), filed for ownership of the “Defense of the Ancients” trademark in direct opposition to Valve, as DotA-Allstars (the Riot Games subsidiary company owned by Guinsoo and Steve “Pendragon” Mescon, former community manager for Dota – the company would later be acquired by Blizzard, from Riot Games in 2011). What most people don’t know is that they also filed for ownership of the “DOTA” trademark itself, on the same day – for whatever reason, Pendragon and Guinsoo forgot to publicize that fact. 

Then Rob Pardo of Blizzard also expressed his concern over Valve’s move - one year later, when the mediocre “Blizzard DotA” was revealed to the world, Frank Pearce of Blizzard would share the exact same thoughts on the issue… as would Mike Morhaime of Blizzard. Still, the general consensus was that, for the time being, Blizzard and Valve would keep the peace, and the trademark issue would ultimately be resolved in one way or another, hopefully with Valve acquiring both the DOTA and the “Defense of the Ancients” trademarks.

But sometimes it’s just too good to be true. And it is in this case. Just today, folks found out that about 3 months ago, Blizzard went on an all-out trademark dispute with Valve, over the “DOTA” trademark.
