The UK left the EU on 1 February 2020. However, for a transitional period until 31 December 2020, EU law will continue to apply to and in the UK. This also extends to EU trademark registrations and EU design registrations. All EU rules will therefore remain in full force and nothing will change until 31 December 2020. An EU trademark application is therefore also valid in the UK.
Previously, procedures had been established for a Brexit which would also apply in a "no-deal" scenario. These procedures are now off the table. They need to be renegotiated and at the moment there is no certainty which procedures will apply after 31 December 2020. We expect that even then conversion from an EU registration to a UK registration will be possible but this has become less certain. If a new UK registration is required, it may therefore be wise to register separately now in the UK and not just in the EU. If you have any questions about this, please let us know.
