It is necessary that any change occurred or to be occurred in the address, commercial title and/or type of the Trademark owner should be notified to the registry. 

In this sense, the change of address is of particular significance. Since the registry within the Turkish Patent Institute is regarded as an official registry, any notification made to the address registered in this registry will be valid in accordance with the relevant provisions of the Law of Notification. Consequently, in case there is no declaration concerning the change of address in this registry, any notification related to Trademark or any other issue, which is made by the Institute or third parties, to the address in the registry would be considered valid. This situation may cause loss of right and inconveniences for the Trademark owner.
