Is IP Property?

An anonymous reader writes "In a recent article, Stanford Law Professor Mark Lemley argues that intellectual property is not 'property' in the traditional sense. According to Lemley, while 'free riding' off of someone else's land or other physical property rights is always undesirable, freely benefitting from someone else's intellectual property rights is often the best way to form a free and creative society. Lemley's distinction also points to the unusual fact that in IP, traditional liberals are often calling for less and less government, while conservatives demand regulation in order to protect their exclusive right to use their intellectual creations."
