The Patent Cooperation Treaty (PCT) assists applicants in seeking patent protection internationally for their inventions, helps patent offices with their patent granting decisions, and facilitates public access to a wealth of technical information relating to those inventions.
By filing one international patent application under the PCT, applicants can simultaneously seek protection for an invention in a large number of countries.
ePCT with strong authentication provides online access to the file of your international application and a suite of functions to facilitate monitoring and management during the international phase.
