UMC then filed the case in May 2015 to contest Tsuburaya Productions’ claim on the international licensing rights for Ultraman.
UMC claimed to own the exclusive licensing rights to Ultraman outside of Japan, through a transfer of the rights in 2008 from Saengduenchai to UMC.
Tsuburaya Productions then filed a counter-suit, alleging that the supposed original agreement between Saengduenchai and Tsuburaya Productions made in 1976 was invalid.
Tsuburaya Productions contested UMC’s claim of possessing the international licensing rights for the property.
