Sega Sued BOI For Patent Infringement in Memento Mori

Sega has sued BOI (Bank of Innovation) for patent infringement in Memento Mori. According to the documentation, Memento Mori infringes on five patents that Sega filed when it made Cryptract, which is now defunct. [Thanks, Game Watch!]

Sega is pursuing injunction against Memento Mori and is asking for 1 billion JPY in damages. That doesn’t include the delinquency charge that it wants to add. The lawsuit includes the numbers for the patents that BOI is supposedly infringing upon. They all relate to the internal coding for gacha. For example, 5930111 is a code or formula that lets people fuse rare cards easier.

As BOI received the paperwork on October 21, 2024, it might be a while before we see any updates to this situation. Nintendo filed a lawsuit against Pocketpair for patent infringement due to similarities between Pokemon and Palworld. News of that lawsuit came out in mid-September 2024 and there have been no public updates even as we approach the end of October 2024.

BOI plans to fight against these allegations, as it does not believe it’s infringing on any intellectual rights from Sega. It acknowledges that this will cause significant worry among the players and people involved with the game. It also states that it plans to continue Memento Mori’s service no matter what the outcome of the lawsuit is.

Memento Mori is an AFK RPG (an idle game) that follows witches, who’d been stigmatized by society, being the only hope the world has against calamity. As an idle game, there’s very minimal gameplay. Most of the selling point seems to be the visuals and the music.

Memento Mori is available on Android, iOS, and Windows PC.
