Trade Marks and Designs: Owners of EU trade marks will still have valid EU trademarks in the remaining EU States, but existing EU Trade Marks (EUTMs), and both RCDs and UCDs, no longer apply in the UK since the UK has left the EU. The UK government has brought in legislation to ensure that those holding existing EUTM or RCD registrations will have a new UK equivalent or “clone” right granted automatically and without charge, which will aim to provide continuing protection and enforceability. Filing, priority and seniority dates are all retained.
Database rights: for sui generis database rights, a database created in the UK after 31 January 2020 will no longer be protected, and UK rights owners may find their rights are unenforceable in the EEA. The Government has indicated that it will implement similar domestic law for the protection of databases made in the UK.
Patents: pan-EU patent rights do not exist yet (and Germany has delayed ratification of the Unified Patent Court Agreement until the implications of Brexit are more clear) so there will be limited direct effect on patents from Brexit. The European Patent is independent from the EU and so should not be directly affected by Brexit.
Copyright: Protection of works by copyright isn’t harmonised across the EU and is largely governed by international treaties so it shouldn’t be affected by Brexit,.
