In a preemptive strike (of sorts), videogame producer Activision, the owner of the popular 'Call of Duty: Warzone' series of games, has filed a lawsuit in the U.S. Central District Court for the District of California against Warzone.com LLC which owns and runs a web-based strategy game called 'Warzone,’ seeking a determination that its use of the term is not confusing to consumers.
