Many years ago before Valve released DotA 2, the company had filed for a trademark for DotA 3. The trademark was filed alongside DotA 2 which seemed to indicate that Valve had plans for a possible sequel. However it looks like Valve has since abandoned the DotA 3 trademark, according to the United States Patent and Trademark Office. The USPTO has since classified the trademark as “abandoned because no Statement of Use or Extension Request timely filed after Notice of Allowance was issued.”
After retaining ownership for several years, Valve has abandoned the Dota 3 trademark. Back in 2010, Valve simultaneously registered a pair of trademarks for its stand-alone sequel toDefense of the Ancients, a popular Warcraft III mod. One of those trademarks, Dota 2, would eventually become the hero brawler that nearly 700,000 people play every day. But the other, Dota 3, never materialized. Now, the United States Patent and Trademark Office classifies Dota 3 as “abandoned because no Statement of Use or Extension Request timely filed after Notice of Allowance was issued.” The trademark expired in October.
