Yes but I wonder what the result of applying something substantially similar to that to the entire patent system without exception might be. Also I had in mind "uniform" in addition to "reasonable", ie holders would be permitted only a single set of license terms at a single rate with zero difference regardless of size, volume, etc. Maybe being permitted to change the terms on offer at the end of every 5 year period or so. Or something vaguely like that anyway.

It's really just a thought experiment about how you might kill patent trolls as well as the asymmetric advantages that large corporations enjoy while still maintaining the spirit of funding the R&D done by participants of all sizes.
