Geographical Indication 

A geographical indication is a sign used on goods that have a specific geographical origin and possess qualities or a reputation that are due to that place of origin.  Most commonly, a geographical indication consists of the name of the place of origin of the goods.  Agricultural products typically have qualities that derive from their place of production and are influenced by specific local factors, such as climate and soil.  Whether a sign functions as a geographical indication is a matter of national law and consumer perception.  Geographical indications may be used for a wide variety of agricultural products, such as, for example, "Tuscany" for olive oil produced in a specific area of Italy (protected, for example, in Italy by Law No. 169 of February 5, 1992), or "Roquefort" for cheese produced in France (protected, for example, in the European Union under Regulation (EC) No. 2081/92 and in the United States under US Certification Registration Mark No. 571.798).
