PCT Patent Application

« Back to Glossary Index

The Patent Cooperation Treaty (PCT) is a legal agreement entered into between various countries for filing patent applications. The purpose of the PCT is to streamline the initial filing process by allowing an applicant to file a patent application (i.e., a “PCT Patent Application”) in a large number of countries. Thus, an inventor can file a single PCT Patent Application in one language with a Receiving Office in order to simultaneously seek protection for an invention in the PCT member countries. Some advantages include:

  • Simplifying the process of filing patent applications in multiple countries
  • Delaying the expenses associated with applying for patent protection in foreign countries
  • Allowing the inventor more time to assess the commercial viability of their invention
