In most countries in Europe, Intellectual Property (IP) arising from academic research is owned by the academic institutions, not the academics themselves. The result is that the academic founders of most biotech companies don't own their IP. 

The same "institutional ownership" model has existed in the US since 1980. Before then, the US government owned the rights to publicly funded research. The 1980 Bayh-Dole act changed the ownership model, such that US universities became able to claim ownership of IP resulting from that research. A dramatic increase in the commercialisation of academic research followed. 

After the success in the US, most European countries decided to adopt a similar system. It seems intuitive that universities would be incentivised to innovate by rewarding them with IP ownership. But European countries were not starting from the same position as the US. Whereas the US moved from a system of government ownership to one of institutional ownership, most European countries allowed academics to retain their IP ("the professor's privilege") before the institutional ownership model was adopted. 

There are good reasons for placing ownership of IP and responsibility for its commercialisation with dedicated tech transfer offices rather than with busy, research-focused academics. But the case of Norway post-2003, discussed in this article, is thought-provoking. A move from the professor's privilege model to an institutional ownership model led to an apparent decrease in the level of university innovation. 

Now that the institutional ownership system and the role of TTOs are well-established in Europe, might increases in university innovation be achieved by rewarding academics with a share of IP ownership?
