Dota trademark dispute between the Valve and Blizzard


According to foreign media reports, months of DotA trademark dispute has now ended, Valve and Blizzard come to an agreement on using DotA trademark: Valve will continue using the name DOTA in commercial publicity activities, new Dota2 will not be affected in any way. But Blizzard can only use dota name on the “War craft 3” and “Star Craft 2” MOD which made by the game player. This also makes the official works Blizzard DOTA which Blizzard released before will be renamed Blizzard All-Star.
Dota is short for DefenseoftheAncients, derived from the user making a “Warcraft3” MOD. In 2010, Valve officially disclosed Dota2 development plan, attracted considerable media attention. IceFrog Dota who was the Dota maps of the original designer also was disclosed to join Valve Dota2.
Blizzard has indicated in the past that, given the Vavle without any previous Dota related products, the use of Dota2 trademark is extremely an inappropriate behavior. Earlier in 2012, “Warcraft3” producer had filed a trademark application, hoped to prevent the Valve to use the Dota trademark.
But Blizzard may also have to abide by the related blizzard trademark protection act. We have reason to believe that the competition of foreign game manufacturers for the trademark DOTA will get worse in the future.
