Copyright is one of four categories that comprise "intellectual property."
In general terms, intellectual property is any product of the human intellect that the law protects from unauthorized use by others. The ownership of intellectual property inherently creates a limited monopoly in the protected property. Intellectual property is traditionally comprised of four categories: patent, copyright, trademark, and trade secrets.

This guide focuses on copyright as it applies to your intellectual property rights as an author.
