Blizzard may have to change the name of its newly-announced multiplayer online shooter, Overwatch.

The game was announced in November 2014 at BlizzCon. Blizzard filed a trademark for the game in April 2014.

However, the United States Patent and Trademark Office has suspended Blizzard's trademark applications due to an existing trademark for the name Overwatch by Canadian company Innovis Labs, Inc.

The United States Patent and Trademark Office has suspended Blizzard's applications pending the allowance or abandonment of the prior application by Innovis.

Overwatch will go into beta this year.
