Electronic Arts is facing resistance to another recent trademark filing.

Ubisoft has filed legal action against EA's application to trademark the word "ghost" for use with Ghost Games, the studio behind the new Need For Speed.

According to Ubisoft, such a trademark would conflict with its own Ghost Recon trademark, in use since 2001.

"Applicant's Mark so resembles Opposer's Ghost Recon marks alleged herein as to be likely [...] to cause confusion, to cause mistake, or to deceive," says the filing.

Regardless of how the U.S. Patent and Trademark Office rules, it seems unlikely that EA will change the name of its studio, given its recent refusal to change the title of Unravel despite the existence of children's tabletop title Beary's Unravel Games.

Neither company raised any issue publicly with the existence of Activision's Call of Duty: Ghosts.

EA must respond to the Ubisoft filing by March 9th.
