It's dramatic and thrilling
More interesting than the financial world !!

Patent Mafia, Patent Goro.
A derogatory term for those who are suspected of infringing their own patent rights and who seek to obtain huge amounts of compensation or license fees by exercising their patent rights. Many can exercise their rights bullishly because they do not manufacture products or provide services using the patent and there is no risk of patent infringement by others.


The stage is the car navigation industry, which can be said to be a mass of patents. A young man from the Intellectual Property Department of a major car navigation manufacturer colludes with the Patent Mafia to take over. A clever trap that can be set through the patent laws of Japan and overseas and the patent networks of each company. A thrilling world that has never been written due to the peculiarities of this field!
