Signed in Stockholm on July 14, 1967, and effective on April 26, 1970, the Convention established the World Intellectual Property Organization (WIPO), tasked with promoting the protection of intellectual property worldwide. The Convention also confers on WIPO the role of administrator of international treaties on intellectual property, such as, among others, the Patent Cooperation Treaty, the Paris Convention for the Protection of Industrial Property, and the Madrid System for the International Registration of Marks.
