Korean game developer PUBG, a subsidiary of Bluehole, has filed a copyright violation lawsuit against U.S.-based Epic Games, asking a court to determine whether the latter's "Fortnite" was copied from the former's "PlayerUnknown's Battlegrounds."



A PUBG official said Friday that the firm filed an injunction, alleging copyright infringement, with the Seoul Central District Court against Epic Games Korea.



"We filed the suit to protect our copyright in January," said the official.
