Reporting an error

If you have noticed an error by the D.P.I. with the details in your ownership title, certificate of identity or entries on the Patents Register, you can report it to enable the D.P.I. to make the necessary corrections. 


PLEASE NOTE: if you are responsible for the error, refer to the section “Updating patent information”.



The correction application must concern a patent that has been granted and published. The correction application may also concern a European patent that has been granted and which designates Monaco.



Who can report an error?

  • the name and address of the person requesting a correction
  • the number of the patent concerned
  • the location of the error in the Industrial Property Annex to the Official Journal of Monaco (Journal number, page number of the Annex).


Please note: If the error concerns the ownership title or certificate of identity, you should attach a copy of the relevant part of the document.



How much does a correction cost?

The correction is free if the error was caused by the D.P.I.
