Chaum's reported demands for patent licensing fees were consistently
above 10-20% of the service revenue plus a significant up front fee.
Those levels are more usually associate with a monopolistic patent,
hence 'monopoly rent'.

The fact that Chaum didn't have the monopoly he appeared to imagine
is probably why nobody was queuing up to pay his demands.
