I laugh at people like JTORENCE. He rips Leo and company on a daily basis with nonsense posts and yet the clown never even new that U of P gets a 5% royalty. It's been in effect since 2003. Just shows you how screwed up they are over and will say anything to scare people away from IPIX.
BTW It's not officially 5% unless B is used as a coating for medical devices.
Until then it's 3.5%
