This document provides an overview of intellectual property, including patents, trademarks, and copyright. It discusses the constitutional basis and key laws governing copyright in the United States. Copyright protects original works fixed in a tangible medium, including literary works, music, art, films, and software. To be copyrightable, works must be creative, novel, and involve intellectual effort in their creation. The rights of copyright holders include reproduction, creation of derivatives, distribution, and public performance or display. However, copyright also faces criticism for being too protective in some cases.
