The Patent Cooperation Treaty, PCT, is a worldwide convention, open to any Paris Convention country. The PCT entered into force in 1978. Unlike the Paris Convention, which addresses substantive intellectual property rights, the PCT addresses procedural requirements, aiming to simplify the filing, searching, and publication of international patent applications.
