Most owners of copyrights will be interested in the civil penalties associated with unjust enrichment based upon their work. However, Japanese law also authorizes criminal penalties in certain circumstances of copyright infringement.
Not all unauthorized uses of copyrighted material can be the basis for a infringement litigation. Some types of behavior that would otherwise be infringing are allowed under the Copyright Act. For example, use of copyrighted material in schools for educational purposes is generally allowed under the Copyright Act. Therefore, if a teacher copies passages out of a novel to create homework for his or her students, the copyright owner cannot sue the teacher for infringement.
Owning a copyright prevents others from copying your work. This is helpful to maintain the integrity of your brand but merely preventing copying by itself does not generate any revenue for the copyright owner. In order to monetize your copyrights, it is important to enter into licensing agreements with other parties who wish to copy your work.
When licensing a patent to another party it is possible to register the license with the Japanese Patent Office. However, registering a license is not required in every case. Generally, the only licenses that need to be registered are exclusive licenses.
