The Office of International Patent Cooperation (OIPC) was established in 2014 to support and improve the international patent system. The office leads efforts to assist U.S. inventors and businesses in protecting their patent rights worldwide and supports the global innovation community.
We strive to improve the international patent system in two critical areas: increasing certainty of intellectual property (IP) rights and reducing costs for international stakeholders. Find out more about our initiatives and programs, which aim to improve quality and timeliness for international patent filers.
