Patent Filing in Japan – The Routes

If you want a patent in Japan, you may use the following options:

1.     Direct Filing with the Japanese Intellectual Property Office (JPO)

2.     International Filing via Patent Cooperation Treaty (PCT)

3.     International Filing via Paris Convention

  • This option is similar to PCT. Hence, the Paris Convention allows simultaneous multi-country filing.
  • Paris Convention has 177 Contracting States and is also administered by WIPO.
  • However, the granting of a patent in Japan remains under the control of the JPO.
  • The Paris convention offers a relatively faster route as compared to the PCT and it is more economical.
