Patent Cooperation Treaty Links
The Patent Cooperation Treaty (PCT) is an international agreement for filing patent applications having effect in many countries around the world. Although the PCT system does not provide for the grant of “an international patent”, the system simplifies the process of filing patent applications, delays the expenses associated with applying for patent protection in foreign countries, and allows the inventor more time to assess the commercial viability of his/her invention. Under the PCT, an inventor can file a single international patent application in one language with one patent office in order to simultaneously seek protection for an invention in the PCT member countries (source: USPTO Inventor Resources).
