"The patent system, which protects property rights in ideas, was systematized in the Statute of Monopolies legislated by the English Parliament in 1623, partially as an attempt to stop the king from arbitrarily granting "letters patent" to whomever he wanted--effectively granting exclusive rights to undertake certain activities or businesses. The striking thing about the evidence on patenting in the United States is that people who were granted patents came from all sorts of backgrounds and all walks of life, not just the rich and the elite. Many made fortunes based on their patents. Take Thomas Edison, the inventor of the phonogram and the lightbulb and the founder of General Electric, still one of the world's largest companies."
