Why is there a difference in pricing for molecular beacons depending on whether I have a license or not?

Our license to the technology requires that we pay a royalty for molecular beacons sold to institutions that do not have a license from The Public Health Research Institute of New York (PHRI). If you have a license, we do not have to pay a royalty to PHRI on your beacon. When you place your first order for a molecular beacon, we will ask if you have a license from PHRI.
