The Open Source Seed Initiative (OSSI) was established in May 2012 to create a system of licensing for seeds. The barriers to including a license with the seeds was determined to be too high, so the organization decided to use a pledge instead.
This Open Source Seed Pledge is intended to ensure your freedom to use the seed contained herein in any way you choose, and to make sure those freedoms are enjoyed by all subsequent users. By opening this packet, you pledge that you will not restrict others’ use of these seeds and their derivatives by patents, licenses, or any other means. You pledge that if you transfer these seeds or their derivatives you will acknowledge the source of these seeds and accompany your transfer with this pledge.
