A patent is an exclusive right granted by countries or communities for the protection of inventions, whether products or processes, that offer a new technical solution or provide a new way of doing something, during a limited period of time, usually 20 years. In return of this limited monopoly, the owner of a patent must disclose the invention to the public, in the patent application. A patent is a territorial right and has its effects within the national boundaries of the country for which it was granted.

In order to get patent protection, inventors must file a patent application, since registration is a requirement in order to obtain protection.

Example of a patent:  Tinting Plastic Optical Lenses
