Joint opposition against patent for Syngenta on a tomato

In 2015, the European Patent Office (EPO) granted patent EP 1515600 to Syngenta. This patent covers tomatoes with a high content of so-called flavonols, which are supposedly beneficial to health. This “invention”, however, is simply a product of crossing varieties from Latin America with varieties currently grown in the West. European Patent Law prohibits patents on plant varieties and on conventional breeding.

European Patent Law gives every citizen of their member states the right to file an opposition against a patent. To stop Syngenta profiting from life, we are filing an official opposition with the European Patent Office to this patent.
