In 2003 the European Union is seeking to restrict the use of region names as trademarks for speciality food and drink to manufacturers from the region. Extending these restrictions outside Europe is controversial because regional names that are trademarks within Europe are often considered generic in other countries. It is made even more difficult where regional names have been trademarked outside Europe, such as Parma ham, which is trademarked in Canada by a Canadian manufacturer, preventing the manufacturers from Parma from using their own name. Products affected include Champagne, Bordeaux and many other wine names, Roquefort, Parmesan and Feta cheese, Scotch whisky and Parma ham. In the 1990s the Parma consortium successfully sued the Asda supermarket chain to prevent it using the trademark Parma on ham not produced and packed in Parma. See Protected Designation of Origin.
