How does conversion work? Owners of EU trademarks or designs will be granted a term (for example 6 months) to specifically convert their rights into national rights in the UK. The procedure will be the same as a normal national application in the UK. Meaning the same costs, but also the examination of the authorities (on absolute grounds) and opposition possibilities for third parties. Do not close your eyes for these matters. Anticipate if the UK market is relevant. In case of filing for a European Union trademark or European design, also request protection through a National registration in the UK.
