IRAN became a member to the PCT (Patent Cooperation Treaty)
On 4 July 2013, the Islamic Republic of Iran deposited its instrument of ratification to the PCT, thus becoming the 148th Contracting State of the PCT, and on 4 October 2013, will become bound by the PCT. Consequently, any international application filed on or after 4 October 2013 will automatically include the designation of the Islamic Republic of Iran.
Also, because the Islamic Republic of Iran will be bound by Chapter II of the PCT, it will automatically be elected in any demand for international preliminary examination filed in respect of an international application filed on or after 4 October 2013. Furthermore, nationals and residents of the Islamic Republic of Iran will be entitled, as from 4 October 2013, to file international applications under the PCT.
