Yes. There is certainly evidence that some use of patents is designed primarily not in the pursuit of invention and innovation but designed in defence of existing marketplace positions of one kind or another, some of them more distantly related to innovation and substance than others.
So there's no doubt that there are some real issues there. I would have to say, however, that the various tracks that our review went down in seeking potential ways of dealing with that problem did not lead to dramatic proposals so to do.
We had a very hard look at the patent pricing system. We had a hard look at the research and the evidence around the effects of different pricing strategies, either for registering patents or continuing to hold patents. We had a look at the rules that apply whether or not it might, for example, be sensible to charge a lower price for patent registration to smaller companies. That was something that was advocated to the review strongly from some quarters.
