Did You Say "Intellectual Property"? It's a Seductive Mirage

It has become fashionable to describe copyright, patents, and trademarks as "intellectual property". This fashion did not arise by accident--the term systematically distorts and confuses these issues, and its use was and is promoted by those who gain from this confusion. Anyone wishing to think clearly about any of these laws would do well to reject the term.
