Renunciation of a plant variety certificate is made by means of a written declaration. It is formulated to the person in charge of the missions of the national plant variety authority by the owner of the certificate or by a representative with a special power of attorney. If the certificate belongs to several persons, renunciation may only be made if it is requested by all of them.
If the real, pledge or licence rights have been entered in the National Register of Plant Variety Certificates, renunciation is only admissible if it is accompanied by the consent of the holders of these rights.
Renunciation is entered after payment of the cancellation fee to the National Register of Plant Variety Certificates. It takes effect on the date of this entry.
