<blockquote>From phony copyright notices attached to the U.S. Constitution, to lawsuits attacking people who poke fun at Barbie, to costly fights over digital sampling in hip-hop, overreaching claims of intellectual property rights are everywhere. Overreaching interferes with legitimate uses and reproduction of a wide variety of works, imposes enormous social and economic costs, and stifles creative endeavors, in areas ranging from documentary filmmaking to university education to fan fiction.</blockquote>
