A U.S.-based discussion of patents and intellectual property rights might go back all the way, say, to the 1980s to discuss the premises of things like software patents and problems with the patent office. By contrast, Dr. Karel Cada, President of the Czech Industrial Property Office, opens his discussion of patents by citing Aristotle, Kant, Leibnitz, John Stuart Mill and Abraham Lincoln. Cool (that's the official American reaction at a more intellectually-grounded European).
