One of the slightly unfortunate things about golden rice (and there are quite a lot of them) is that the state funding it was developed with required them to patent it and sell the patent to the private sector. Though not patenting it would've been of limited help due to the thicket of patents covering the technologies they used.
I think the organization funding it (which if I recall correctly was the EU) wanted the university research they were funding to turn into commercial products, and so set a blanket rule requring patenting and attempts at commercial licensing. This is a fairly common view on government-funded research these days unfortunately. There was a published report by the main researcher somewhere with more details.
Well, that was a stupid idea, then. Instead of selling the patents of public research to private monopolies, they should have made them available to everybody.
