Patent Law Treaty (2000)

The Patent Law Treaty (PLT) aims to harmonise and streamline formal procedures in respect of national and regional patent applications and patents, making those procedures more user-friendly.

The PLT was agreed on June 1, 2000 and entered into force on April 28, 2005. Ireland deposited its instrument of ratification for the Patent Law Treaty at the World Intellectual Property Organisation (WIPO) in Geneva on 27 February 2012 and it came into effect in Ireland on 27 May 2012.
