About us

The Trilateral Co-operation was set up in 1983 between

  • the European Patent Office (EPO),
  • the Japan Patent Office (JPO) and
  • the United States Patent and Trademark Office (USPTO)

Vision statement

The Trilateral Offices, sharing a solid common history at the forefront of international patent co-operation, endeavour to:

  • coordinate their responses to the current and future global challenges of the patent system, 
  • collectively adapt to technical advances and changes affecting the IP environment,  
  • advance and strengthen their co-operation with users, and 
  • co-operate as a think tank on devising innovative concepts for enhanced collaboration and the sharing, effective use, and leveraging of work products and on continuously optimising the patent system for the benefit of offices, stakeholders and society at large.
