Say for example I discovered how to unify General Relativity with Quantum Mechanics and then someone else uses this improved understanding of physics to engineer a new product which would have been impossible without it. Am I entitled to a portion of the revenue generated by the new product? What about all the electronics now on the market that rely heavily on principles of quantum mechanics? Can the physicists who discovered those principals (or their heirs) claim a portion of the revenue generated? What about the universities or laboratories that funded the research that resulted in said discoveries?
