Technical fault in the European Patent Register

Désolé. Actuellement, cette page n'existe pas en français.

We are currently experiencing some issues with the European Patent Register. Users are seeing a message "Your connection is not secure / There is a problem with this website's security certificate / Your connection to this site is not secure ".

This is caused by an elapsed security certificate.

Customers can still access the Register by selecting "Continue to this website / Advanced -> Add exception / Advanced -> Proceed to register.epo.org"

Our technicians are working to fix the problem as soon as possible.

We apologise for any inconvenience.
