The Plant Breeders' Rights (Information Notices) Regulations 1998
Section 14(2) of the Plant Varieties Act 1997 provides that, in infringement proceedings, certain presumptions apply in respect of harvested material which is the subject of an information notice if the information requested in the notice is not provided within a prescribed period. The presumptions are that the material was obtained through unauthorised use of propagating material and that the holder of plant breeders' rights in the material did not have a reasonable opportunity before the material was obtained to exercise his rights in relation to the unauthorised use of the propagating material.
