I think that agrotech companies provided licenses for free to use their proprietary technology (at least that's what the golden rice initiiative claims) "A licence to those technologies was obtained from Syngenta. The package contained proprietary technologies belonging not only to Syngenta but also to Bayer AG, Monsanto Co, Orynova BV, and Zeneca Mogen BV.These companies provided access to the required technologies free of charge, for humanitarian purposes." http://www.goldenrice.org/Content1-Who/who4_IP.php
