Legal experts in New Zealand are warning food and drink producers to get ready to see the names of some of their products outlawed. Mounting trademark pressure in the European Union is seeing more names currently used as generic terms ring fenced for use by producers in the specific regions where they originated. Greece has moved to prohibit use of the word 'feta,' while the Czech Republic is hankering to restrict the term 'pilsner'. Italy has made great advances in protecting the word 'parmesan' and Spain is well on the way to gaining exclusive rights to 'sherry'.
