It is now officially impossible to claim to have invented something which has been in public use for centuries. On 10 May 2000, the European Patent Office (EPO) revoked a patent which had been granted to the United States of America and multinational corporation W. R. Grace for a fungicide derived from seeds of the neem tree. Since time immemorial, neem has been a tree popular for its versatile leaves, for reforestation and for its seeds, which contain a natural pesticide and insecticide. A coalition of environmental NGOs (including IFOAM) and politicians lodged an official objection to the patent five years ago. The EPO accepted the objection with the argumentation that the invention lacked an inventive step and novelty . A wiser approach was taken by Moctar Sacandé of the Centre National de Semences Forestières in Burkina Faso. He discovered a method to keep dried neem seeds and shared this with the public. Neem seeds are notoriously difficult to store; once dried, the seeds no longer germinate upon soaking, in contrast to seeds such as wheat and maize. Sacandé discovered that when dried to a moisture content below 10% the seeds keep for more than two years with a germination rate of 50%. However, soaking can damage the seed membranes. Soaking the dry seeds in water at a temperature of 35 °C prevents this imbibitional damage.
