'Do Not Privatize the Giant's Shoulders': Rethinking Patents in Plant Breeding.

Intellectual property rights (IPRs) have increasing impacts on plant breeding. Not only varieties but also germplasm and technologies are protected. Intellectual property has also affected corporate concentration in the seed supply chain. While not very controversial in the USA, it is increasingly controversial in Europe after rulings on plant patents concerning nontransgenic crops in 2015. Both political and industry voices call for new interpretations or legislations. Industry initiatives have opened facilitated patent access systems designated 'free access, but not access for free'. Although praiseworthy, they are voluntary and so far limited to vegetable crops. This Opinion article suggests a mandatory system of declaring IPR use linked to variety registration. This compulsory licensing system with 'toll roads, not road blocks', is likely to reward IPRs without delaying breeding progress.
