Renewing a patent

Paying an annuity or renewal fee will maintain your patent for a period of up to 20 years. After that period, your invention will enter the public domain, i.e. it will no longer be protected and anyone can use it.



You must pay the first annuity when you file the patent application.  The second annuity must then be paid before the anniversary date of your patent application.


See below “When should annuities be paid?”


Important: you must pay the annuities, even if your patent has not yet been granted.  Otherwise, the patent may lapse.


Who can pay annuities?

Anyone can pay the annuities on a patent.


When should annuities be paid?

Annuities must be paid by the anniversary date of the patent application.

For example, the annuities for a patent filed on 15 July 2015 can be paid up until 15 July of each year.


For patents granted by the European Patent Office designating Monaco, annuities must be paid by the last day of the anniversary month of the filing.

For example, the annuities for a patent filed on 2 May 2009 can be paid up until 31 May of each year.



However, payment may still be made within an additional grace period of six months, from the day after the deadline. In this case, you will need to pay late fees equivalent to 20% of the annuity due.


If you have been unable to pay your annuity after this six-month grace period, the patent will lapse.


The payment date is the date of the postal stamp in the case of payments sent by mail, or the date on which the DPI’s account is credited (the value date indicated by the banking institution) for payments made by wire transfer.


Important: annuities must be paid to the DPI every year at the patent holder’s initiative, and may not be paid more than one year in advance.


How much does an annuity cost?

The cost of an annuity varies depending on the number of years and applicable discounts.
