The Open Source Seed Initiative

Today, only a handful of companies account for most of the world’s commercial breeding and seed sales. Increasingly, patenting and restrictive contracts are used to enhance the power and control of these companies over the seeds and the farmers that feed the world.

Patented and protected seeds cannot be saved, replanted, or shared by farmers and gardeners. And because there is no research exemption for patented material, plant breeders at universities and small seed companies cannot use patented seed to create the new crop varieties that should be the foundation of a just and sustainable agriculture.

Inspired by the free and open source software movement that has provided alternatives to proprietary software, OSSI was created to free the seed – to make sure that the genes in at least some seed can never be locked away from use by intellectual property rights.
