We have a number of metrics that we continue, and to Alison's point, the challenge of getting at the right metrics in the intellectual property space is a hard one. The number of patents filed is only one indicator. We have licensing revenue, for instance, that comes into the institution.
However, to Alison's point from earlier, licensing revenue often doesn't tell you a complete story either, because you can tell how much the university has earned from it, but that's not necessarily a full indication of whether or not that was the best value you could have gotten out of the intellectual property. There may have been a race to license as opposed to a race to bundle.
