Essentially Derived Varieties in View of New Breeding Technologies – Plant Breeders’ Rights at a Crossroads

Abstract

Abstract Plant breeders’ rights (PBR) within the framework of the International Convention for the Protection of New Varieties of Plants (UPOV) are the sui generis intellectual property (IP) system of choice for plant varieties. It achieves a balance between the protection of new varieties and access to protected breeding material for further improvement. The extension of the protection to essentially derived varieties (EDVs) in the UPOV 1991 Convention1 was controversial from the beginning as it creates a tension with the breeders’ exemption. The 2017 UPOV Explanatory Notes on EDVs further fueled the debate as they were seen to limit the EDV extension, while some argue that the EDV scope should extend to all predominantly derived varieties merely on the basis of genetic conformity. With the rise of new breeding technologies (NBTs), legal certainty on the EDV definition is of fundamental importance to avoid a chilling effect on these promising technologies. Not only would a broad EDV definition block critical innovation and restrict the full potential of NBTs to a few multinational companies,2 it would also substantially limit the scope of protection of NBT-derived varieties, as an EDV itself is not entitled to the EDV extension: Valuable NBT-derived varieties would become easy prey for plagiarism. This article shows that the legislative intent of the EDV provision does not limit innovative breeding to conventional crossing and that there is no basis for extending EDV protection to new, innovative varieties which do not retain the essential characteristics of the initial variety (IV) even if there is a high genetic conformity. By analogy with the doctrine of equivalents under the patent system, a derived variety cannot qualify as an EDV if it (i) does not retain all the essential characteristic of the IV and (ii) is ‘non-obvious’ and causes a ‘significant technical progress of considerable economic interest’. The article finally suggests guidelines and processes to overcome the current EDV dilemma.
