Lost in the mail: address for service at UK IPO post-Brexit

From January 1, 2021, an address for service (AFS) in the UK, Gibraltar or Channel Islands has been required to file trademark and design applications at the UK Intellectual Property Office (UKIPO). Prior to this date, an address in the European Economic Area (EEA) was also acceptable for filing such applications, but the end of the Brexit transitional period on December 31, 2020, brought about a change in practice.
