Cost required for patent application from foreign country to Japan


About patent fees


■ In order to apply for a patent from foreign country to Japan, there are “Direct Route” to apply directly in Japan and “PCT Route” to designate Japan by PCT international application.

■ The cost of the “PCT route” is the same as the direct application route except that the examination fee in Japan is slightly reduced.

■ In order to obtain a patent, there are costs incurred at the filing stage, the examination request stage, the examination stage (intermediate process), the registration stage, and the maintenance stage.

■ Please see the Patent Office website “Schedule of fees” (external link) for details of the fees of the Japan Patent Office.
