There are treaties between groups of countries organized around the basic concept of protecting an owner's exclusive right to market their goods under their name and trademark. These economic alliances have adopted policies that simplify trademark administration, secure property rights of mark owners and encourage fair trade in commercial endeavors. The main organizations are the European Union (EU), the Madrid System, the Organisation Africaine de la Propriété Intellectuelle (OAPI), and the African Regional Intellectual Property Organization (ARIPO).
