Rather different things. The right to own property and do what you want with it, outside of a relatively limited set of prohibitions, is a fundamental right that forms the basis of our economy. Patents are an artificial construct created for a specific purpose with specific limitations. They are meant to encourage technological innovation by providing temporary Government protection for the inventor in exchange for a disclosure of the details of the technology. For an entity that has not invented anything and has no intention to do any research or sell any products to use them to extort rents from companies that actually do those things is a distortion of the purpose of the system.
