The patent, EP3560330, granted to the German company KWS by the European Patent Office (EPO) in June 2022, covers maize with improved digestibility which is primarily purposed for animal feed production. It claims plants with randomly mutated genes and their harvest and the feed produced thereof. It covers, in addition, the usage of naturally occurring genetic variations for conventional breeding.
