The IP5 is a forum of the five largest intellectual property offices in the world, including the U.S. Patent and Trademark Office, European Patent Office, Japan Patent Office, Korean Intellectual Property Office and China’s State Intellectual Property Office.

The IP5 offices account for 90 percent of all patent applications filed worldwide and 93 percent of all work carried out under the Patent Cooperation Treaty. The vision of the IP5 offices is global cooperation, which has been defined as “the elimination of unnecessary duplication of work among the IP5 offices, the enhancement of patent examination efficiency and quality and guarantee of the stability of patent right.”
