The impact of different intellectual property approaches on the spreading of green technologies is debated on Seed Magazine, which gathered five experts and asked them to answer the following question: “How can we reconcile the useful qualities of the current patent system with the need for widespread use of green tech?”. The answers come from people with different backgrounds and different kind of involvement with the open access movement: Federico Caprotti, John Wilbanks, Michele Boldrin, Carlos Serrano and Dennis Pamlin. Their proposals are quiet diverse but they agree on the necessity of acting ont the link between IPRs and technological innovation.
