To comment on that, in the U.S. there are actually quite a few murmurings about whether the Bayh-Dole Act has outlived its useful purpose. There was a recent court case, Stanford v. Roche, where the university's claim to ownership of an inventor's IP was challenged. It has caused great consternation among my U.S. colleagues.
The Kauffman Foundation in the U.S. is also advocating for a more open IP ownership policy. In Canada we have this policy-driven IP environment at the universities, and I wouldn't advocate for a creator-owned approach, necessarily. I think it really comes down to the culture of the institution. At our university it works because we have entrepreneurially oriented faculty members, and it's better sometimes just to get out of the way and let them go with it. But in other universities, where the culture is not that way, maybe nothing would happen if you didn't have an institution that owned the IP and at least took some proactive steps to protect it and try to push it out there.
True to the Canadian spirit, there's something to be said about diversity and embracing the diversity of different IP policies, and it is quite interesting to see what is going on in the U.S. right now. They're possibly migrating to a policy framework that we have here in Canada.
