Trilateral Offices

The so-called Trilateral Offices, or Trilateral Patent Offices, are a group of patent offices consisting of the European Patent Office (EPO), the Japanese Patent Office (JPO) and the United States Patent and Trademark Office (USPTO). 89 % of the patents in force in the world are either European patents (or part of European patent in a contracting state), Japanese patents or US patents [1].
