In order for a trademark to remain valid, many countries require that the mark is actively being used for the goods and services for which it has been registered. If your mark is not used within a consecutive period of five years, you will risk having your trademark cancelled through a cancellation proceeding.
In many countries a trademark registration may also be cancelled on other grounds, such as if it has been registered despite existence of prior rights which are likely to be considered as confusingly similar with the registered trademark.
Zacco helps many of our clients manage cancellation actions, and considers the use requirement in our overall approach when implementing trademark strategies. Whether you need to have a trademark cancelled or would like to defend your registration in a cancellation procedure, Zacco can help.
