To solve the common serious problems of patent application surge and backlog of pending files, in 2007 IP institutions of the European Patent Office (EPO), the US Patent and Trademark Office (USPTO), the Japan Patent Office (JPO), the Korean Patent Office (KIPO) and China State Intellectual Property Office (SIPO) established a cooperation mechanism in these five countries / regions.

In the second meeting in October 2008 in Jeju Island of South Korea, the five offices defined the cooperation vision: "to eliminate unnecessary duplication of effort between the offices and improve efficiency and quality of patent examination, to ensure stability of patent ". The five offices considered "work-sharing" as important ideas and the main way for cooperation, with the "quality of timeliness" as a precondition for work-sharing.

Since 2007, a total of seven meetings have been held between Secretaries and thirteen meetings between Deputy Secretaries. Business cooperation has been expanded from ten basic projects at the beginning to dozens of projects under several working groups, many of which have significant international impact.
