Advantages of the Madrid System :
The system of international registration of marks has several advantages for trademark owners. Instead of filing many national applications in all countries of interest, in several different languages, in accordance with different national procedural rules and regulations and paying several different (and often higher) fees, an international registration may be obtained by simply filing one application with the International Bureau (through the Office of the home country), in one language (either English or French) and paying only one set of fees.
Similar advantages exist when the registration has to be renewed; this involves the simple payment of the necessary fees, every 10 years, to the International Bureau. Likewise, if the international registration is assigned to a third party or any other change, such as a change in name and/or address, has occurred, this may be recorded with effect for all the designated Contracting Parties by means of a single procedural step.
