In order to maintain your exclusive right, you must pay a fee each year – an annual fee. It must be paid in advance and have been received by PRV at the latest on the due date, which is the last day of the month in which your patent application was filed.

When must the annual fee be paid?

The first payment happens when your application is two years old. Then you must pay the annual fees for the first three years at the same time. That applies even if your application is being processed and the patent has not yet been granted. After that, the fee must be paid annually.

Right amount

The annual fees increase gradually during the patent term. In order to be sure that you pay the right amount, you should check what the annual fee is on this website.

No invoice

You must remember yourself to pay the fee at the right time and the right amount, as PRV will not send you an invoice.

20% higher fee

If you do not pay the annual fee by the due date, you have the possibility of paying the amount plus a 20% increase within six months. If the increased fee is not paid within that time, the patent is annulled and you have lost your exclusive right.
