I can comment. The intention of a patent is to grant market exclusivity. As it was designed, it's supposed to be a reward for innovation. The intention behind it is to prevent competition. In our experience, the ways in which we have been able to access lower-cost medicines is through competition. Patent extensions will keep prices higher. I think that's clear, and I don't think that it incentivizes companies in the way that we think that it does.
