Well, in some ways our patent system is too strict. If you look at the U.S. Supreme Court, for example, or if you look at the U.K. courts, they're actually softening some of the rules around non-obviousness, about patentable subject matter. We're moving or have moved in the opposite direction. So we need greater flexibility on that side. I think it should be done by the courts or by the Canadian Intellectual Property Office.
But in terms of legislative change to increase it, there's no evidence that I have seen to indicate that giving greater rights or longer rights would increase innovation. In fact, it will just increase the transaction costs that get in the way of collaborations.
