So this clause, as Madam Chair will be aware, relates to intellectual property (IP). Now, intellectual property is a crucial part of any commercial activity. In fact, one of the interesting things, if you look at the Government's balance sheet, is intellectual property is only worth $3 billion. In my view, it's highly understated. But, for most companies, people are the most important thing, but the next most important thing is intellectual property. In some instances, companies will want to protect that and they'll go through a patent application process. They might go to the next stage down, which is a licensing arrangement, or they may choose, because the difficulty in around—protecting the commercial IP is very, very difficult.
