Patents protect intellectual property related to inventions or processes, and are distinct from other types of intellectual property protections like copyrights or trademarks. A patent may be granted to an inventor of things like a new drug formula, a new manufacturing method, or a new piece of technology. Once granted, a patent allows the owner to maintain sole control over who can produce the protected item or who may utilize a protected process. Like other forms of intellectual property protections, patent law must balance the rights of a patent owner with those of the public. Because of this need, patents are restricted to ensure free speech and the open exchange of information.
