Square Enix, a Japanese conglomerate, has been in the middle of a major revamp both in Japan and abroad. They have recently sold three of their overseas studios to a Swedish company called Embracer Group, in a bid to focus their resources on developing AAA games.

Now, according to the publication of the gazette of the Japan Patent Office, Square Enix has filed a registration for two trademarks under Class 9, which is reserved for machinery and equipment including commercial video game machine software, programs, and virtual reality game software.


  • Square Enix has filed a trademark registration for The Portopia Serial Murder Mystery and PARANOMASIGHT in Japan.
  • It was revealed in the latest publication of the gazette of the Japan Patent Office. 
  • The registrations were filed under Class 9 which includes gaming machine software, program, and virtual reality game software.
  • The purpose of this filing is unknown.
  • Square Enix is yet to comment on this.

One of the filed trademark registration is for a Japanese mystery visual novel adventure video game, The Portopia Serial Murder Case, developed by Yoji Horii and Koichi Nakamura. The trademark for the title was originally filed in 1985 and was accepted in 1988. So Square Enix has filed for a new trademark for the title.
