If another party patents an invention which builds on my own, do they have to get a license from me before they can start manufacturing their product? For example, if I invented the 'chair', and later someone comes up with the novel idea of a 'chair with inbuilt drink holder', can they go ahead an manufacture the 'chair with inbuilt drink holder' without permission from me?


If they use your patented invention, they need to obtain a license from you. If you want to use their improvement, you would need to obtain a license from them.
