A Florida-based multimedia company called Epic Stone Group is claiming that they trademarked the term/phrase "Battle Angel" back in 2009 despite the fact that the Battle Angel Alita Manga was first created in 1990, some 19 years earlier.
Their claim is pretty clearly baseless and is likely not to have any effect on the potential future of the franchise.
