 At the most practical level, the subject matter of intellectual property is largely codified in Anglo-American copyright, patent, and trade secret law, as well as in the moral rights granted to authors and inventors within the continental European doctrine. Although these systems of property encompass much of what is thought to count as intellectual property, they do not map out the entire landscape. Even so, Anglo-American systems of copyright, patent, trade secret, and trademark, along with certain continental doctrines, provide a rich starting point for understanding intellectual property (Moore 1998a). We will take them up in turn.
