Payment of annual fees for a European patent application

The maintenance fees (annuities or renewal fees) are due from the 3rd one (at the latest on the last day of the anniversary month of the filing date of the application before EPO).

They are payable 3 months before the due date.

We send you reminders approximately three months before the due date.

Grace period

The omission of payment can be overcome if the renewal fee is paid during an additionnal grace period of 6 months (e.g: for an application filing date at the 31st of March, the grace period runs from the 1st of April to the 30th of September). The European Patent Office usually sends a notification of warning before forfeiture approximately four months before the end of the grace period.

If the renewal fee remains unpaid at the end of the grace period, the European Patent Office sends a notification indicating that the patent application shall be deemed to be withdrawn if the annuity with fine is not paid in due time.

After grant

The fees have to be paid before the national offices after grant.

For example, for a European patent application filed on 15/05/2006, and granted on 15/01/2009, the 4th renewal fee, due on 31/05/2009, should be paid before the national offices.
