Syngenta fails at the European Patent Office

A patent on the breeding of maize will not be granted

17 January 2018

At a public hearing, the European Patent Office (EPO) today rejected an appeal filed by Syngenta. The company wanted the EPO to grant a patent on the breeding of higher-yield maize plants (EP2121982). At the same time, Syngenta also wanted the EPO to abolish existing restrictions in the field of plant and animal breeding that have only recently been put in place. The EPO also rejected this attempt.

Decisive for the EPO’s decision were technical reasons. Therefore, the content of the patent claims was not defined clearly enough. With this specific patent, maize plants with hereditary factors were to be crossed to achieve higher yielding offspring. However, as the description of the patents shows, the specific genes required to achieve these characteristics were unknown. In this particular instance, sequences of marker DNA that can indicate the presence of the desired genes were to be used for the selection of suitable plants.
