To add to what Tom was saying, you also have an environment right now where there's collaboration going on with researchers. So you can get researchers from multiple institutions working on it, and they each have different IP policies. Our concern is the varying differences between the IP policies that exist. If you have multiple researchers from two universities and a federal lab, you could have three or four different IP policies you need to deal with.
That scares away companies, as well as what Tom was saying. How do they protect that? When you go to an organization and they hand you their IP rules, and it's this thick, if you're a small company you don't have the time to hire a lawyer to review that policy and how you would interact with it.
