It seems we licensed about a hundred companies to date. If there are about 400 potential companies in total, have we already hit on the biggest top 100? Or top 50 ? Or ... ?

Althought the issue of how much a license costs is more complicated than just knowing the total $ size of a company, it would still be informative to see sizing of all those 100 companies. As a rule, a big company will have to pay more than a small company.
