Libertarians and Austrians, including such organizations as the CATO Institute, Von Mises, and the Wall Street Journal, have put forth a number of arguments against patents and intellectual property. These arguments include that ideas (an invention is not just an idea, but I will let that go) are not scarce and therefore patents are not real property rights, patents are monopolies, patents inhibit the growth of technology, patents require the use of force to enforce one’s rights, patents are not natural rights and were not recognized as so by Locke and the founders, among other arguments. I have discussed most of these arguments earlier and will put the links in below. One of their favorite fall back arguments is that patents limit what I can do with my property. For instance, a patent for an airplane (Wright brothers) keeps me from using my own wood, mechanical linkages, engine, cloth, etc. and building an airplane with ailerons (and wing warping). This according to the libertarian argument is obviously absurd. After all it is my property.
