The International Patent Institute (IIB) (French: Institut International des Brevets), established on June 6, 1947, in The Hague, Netherlands, was a multinational intellectual property organization founded by four European countries, namely France, Belgium, Luxembourg and the Netherlands.
This merger resulted in the creation of a branch of the European Patent Office (EPO) in Rijswijk in the Netherlands, near the Hague.
The Rijswijk office is one of three locations along with Munich and Berlin, where European patent applications may be filed.

By centralizing resources and sharing expertise, member countries sought to reduce cost and streamline patent searches, although different approaches to intellectual property were also being explored at the time.
