A Patent Cooperation Treaty (PCT) application, otherwise known as an international patent application, is a single patent application that can be filed which facilitates the filing of patent applications in over 150 countries. PCT application can be useful in delaying the costs of filing foreign patent applications in a large number of countries.
A PCT application can be filed at the International Bureau (IB) or at a competent national or regional office.
