Sega has reportedly filed for patent infringement against Bank of Innovation – the developer of idle RPG MementoMori, and mobile game Genjuu Keiyaku Cryptract.
According to a report from Otaku Sougen (translated by Automaton), Sega is seeking both 1 billion yen in damages (that's over $6.6 million at the current exchange rate) and an injunction for patent infringement. This apparently comes after previous negotiations between the two companies.
