Illektron LLC has challenged gaming giant Electronic Arts Inc. to a match in the U.S. District Court for the Northern District of California on claims of trademark infringement.

Palm Springs, California-based Illektron asserts that EA used Illektron’s “BATTLEZ” trademark to label a feature in its “Plants vs. Zombies” video game, according to a complaint filed Monday. The term was first applied to Illektron’s collectible card game that launched in 2003, which the company developed into a digital game five years later.
