Patent Cooperation Treaty was passed on at Washington on June 19, 1970 and modified on February 3, 1984, and on October 3, 2001. PCT comprises 8 chapters and 69 articles and came in force on April 1, 2002. The Patent Cooperation Treaty assists applicants in finding protection internationally for their inventions, helps patents office with their patent granting decisions, and facilitates public access to the wealth of technical information relating to those inventions. By filing one international patent application under PCT, applicants can seek protection for an invention in many countries throughout the world.
