Ten years from the date of application. After ten years the trademark and/or trade name must be renewed. The trademark and/or trade name can be renewed indefinitely.
The SPTO will advise you in plenty of time when the period is due to expire. It is important that you notify the SPTO of any change of address. It is advisable to indicate an e-mail address as your preferred method of notification, as this is the quickest way of receiving notifications.
However, despite this, please bear in mind that some national registrations that were granted under the old trademark legislation are still in force and therefore, if the application date is before 12 May 1989, you are advised to consult the Office's information services to ascertain your renewal date and any payments due for your national trademark.
