Comment on copyright and possible single payer

I've heard good portion of meds are partly or wholly based on federally funded research.

I say increase Federal Research funding, especially in underfunded areas like antibiotics and less common diseases and change patent law. You must be legally obligated to license any patent at a reasonable portion of a product price royalty. 

That's my view both copyright as well as patents must be obligatorily licensed at a reasonable portion of licensee's product price.
