A wide body of federal and state laws protects creative property such as writing, music, drawings, paintings, photography, and films. Collectively, this body of law is called “intellectual property” law, which includes copyright, trademark, and patent laws, each applicable in various situations and each with its own set of technical rules. When obtaining permission to use creative works, you’re concerned primarily with copyright law. However, trademarks, trade secrets, and publicity and privacy rights sometimes come into play when permission to use certain types of works is sought. Below is a summary of the various types of intellectual property laws that are relevant to the permissions process. Later chapters provide more details as needed.
