I would just add that what happens with these things as well in terms of the intellectual property is that as you tweak and develop something, of course, you can get follow-on patents.

Well, as you go through all of these stages, you get different intellectual property and follow-on rights coming up that inhibit access for other companies that would wish to come in to compete.
