|Executive summary: Copyright
law in the U.S. is governed by federal statute, namely the Copyright Act
of 1976. The Copyright Act prevents the unauthorized copying of a work of
authorship. However, only the copying of the work is prohibited--anyone
may copy the ideas contained within a work. For example, a copyright could
cover a written description of a machine, but the actual machine itself is
not covered. Thus, no one could copy the written description, while anyone
could use the description to build the described machine.
Copyrights can be registered in the Copyright Office in the Library of Congress, but newly created works do not need to be registered. In fact, it is no longer necessary to even place a copyright notice on a work for it to be protected by copyright law. However, the Copyright Act does provide additional benefits to those who register with the Copyright Office. Consequently, copyright registration and the use of a copyright notice is recommended.
The discussion of copyright law is divided into the following parts:
