Japanese IP System

Japanese IP System is supported by several laws.

* Patent law - for invention,
* Utility model law - for utility model,
* Design law - for design,
* Trademark law - for trademark and service mark,
* Copyright law - for work

Japanese patent law system is a first-filing system, in which a person who firstly files an application of a same invention is granted patent. An application usually includes at least one claim, an embodiment, an abstract and drawings in Japanese. An application in English can be filed, but a Japanese translation must be filed by 2 months of the filing date. At the time of filing, there is no need to submit a power of attorney, a declaration and an assignment to Japan Patent Office (JPO).
