Newsletter 2/20: Brexit: Trade marks with protection for the European Union (“EU trade marks”) – what do owners need to look out for and do?
Do you own a trade mark that is protected throughout the entire European Union (“EU trade mark”)? Do you regularly review whether the trade marks you own still correspond to their current use and are thus “fit” for the future? In both cases, we recommend that you read our newsletter and hope that it provides you with food for thought regarding the maintenance of your trademark portfolio now, with Brexit happening, and in the future. We would be pleased to assist you at any time.
