At what time are annual fees due in Japan?
At the grant of a patent, the annual fees for the first three years must be paid all together as a lump sum constituting the registration fee. Further annual fees are due yearly in advance.
For patents granted up to 1996 (old Japanese patent law), annual fees are due for each year as from the date of publication of the examined document. For all patents granted according to the new Japanese patent law (01 January 1996 onwards), the due date for annual fees is the date of grant (registration).
