I want to know the answer to the following question:
What is it called when a law disallows copyright owners from denying a license for certain uses?
All the background I'm provided with is that "Compulsory licensing laws generally say that for certain uses of certain works, no infringement occurs as long as a royalty, at a rate determined by law rather than private negotiation, is paid to the copyright owner or representative copyright collective.". Is that enough to answer the question?
