Thank you for the question.
I will say off the top that you're asking a question that is not really in my area of expertise, nor in my colleagues'.
If we have time, I might turn to my colleague Darryl Patterson, who could offer a few views. You're asking a very big question about IP and patents. We'll certainly do our best, but it may be something we need to return to you on.
Darryl, do you want to try this?
