The Five IP Offices (IP5)

What is the “IP5 Offices”?

The number of patent applications filed with the JPO, the USPTO, the EPO, CNIPA and KIPO is about 80% of the number of all patent applications filed worldwide. The IP5 is a forum established in 2007 that consists of those five largest patent offices in order to lead the global efforts in the intellectual property field. The IP5 Offices discuss issues such as the mutual utilization of examination results, simplification of procedures, and the maintenance and improvement of quality of examinations, in order to respond to the increase in patent applications being filed and the associated increase in workload. Vigorous discussions have been held on the working level in three working groups (WG1: Classification, WG2: Information Technology, and WG3: Examination) etc.

IP5 vision

For the first 10 years since the launch of the IP5, the IP5 Offices have focused on “the elimination of unnecessary duplication of work among the offices, enhancement of patent examination efficiency and quality, and guarantee of the stability of paten right”.

At the tenth IP5 Heads Meeting held in June 2017, the IP5 Offices agreed on a new vision for IP5 cooperation as follows: [i] patent harmonization of practices and procedures, [ii] enhanced work-sharing, [iii] high-quality and timely search and examination results, and [iv] seamless access to patent information. The IP5 Offices are cooperating based on this new IP5 vision.

Since then, the IP5 Offices and the IP5 Industry hold meetings at the high level and the working level and exchange views with each other.
