How to renew your trademark and change register information

A trademark is valid for 10 years from the date of registration. It can be renewed every ten years.

It is in trademark proprietors' interests that our register information is up to date. Co-operation and trading partners may search for information about a trademark or its owner in our register, and we rely on the register when reminding proprietors of due mark renewals. It is therefore important that you notify us if the proprietor's name, company form, address, or other similar details change to ensure that you receive any information addressed to you, for instance, notices from our office.

It is possible to transfer a trademark to another party, or license another party to use your mark. Please note that we enter the change of proprietor and information on licensing in the register only on application.

You must also let us know in writing if you make changes to either the trademark itself or its list of goods and services. The list of goods and services can be limited, but if you want to extend it, you always have to file a new application for registration.
