International Trademark Protection The system of the international registration of marks is administered by WIPO and governed by two treaties- the Madrid Agreement Concerning the International Registration of Marks of 1891 and the Madrid Protocol of 1986, both of which facilitate trademark prosecution in over 60 member states. Since the US joined the Madrid Protocol in 2002, application for the international registration of their trademarks takes place through the domestic federal authority.
