The Community Plant Variety Office (CPVO) is an agency of the European Union, located in Angers, France. It was established in 1994. Its task is to administer a system of plant variety rights, also known as plant breeders' rights, a form of intellectual property right relating to plants. The CPVO works rather like the Office for Harmonization in the Internal Market: it grants intellectual property protection for new plant varieties. These rights are valid for a period of either 25 or 30 years.
