Post Brexit: .eu domain name registrations
In order to own a .eu domain name after the UK exits the EU individuals and entities will need to reside or be established (that is, have their registered office, central administration or principle place of business) within the EU. Domain names not meeting this criteria may be revoked after exit day.
This means that, save for the exception of "well known marks" (as defined under Article 6bis of the Paris Convention), IP rights holders will no longer be able to rely on their UK registered or unregistered rights when seeking to challenge .eu domain names that are subject of speculative and abusive registration.
Holders of .eu top level domains are therefore strongly advised to check whether they will continue to meet the above eligibility criteria. If not, you may wish to discuss transferring your registration(s) to another top level domain such as .com, .co.uk, .net or .org or transfer ownership of such domains to an EU based individual/entity.
