Technical fault in the European Patent Register

Leider ist diese Seite derzeit nicht in deutscher Sprache verfügbar.

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.
