In May 2019, the band filed a $2 million lawsuit against video game company 3D Realms for infringing on their trademark via the planned release of a game called Ion Maiden, which the band claims “is nearly identical to the Iron Maiden trademark in appearance, sound and overall commercial impression.” The suit further accuses 3D Realms of causing “confusion among consumers” by depicting a skull icon similar to the band's Eddie mascot and that "Ion Maiden" is similar to the band's own "Legacy of the Beast" video game.
