The European Patent Office (EPO), the Japan Patent Office (JPO), the Korean Intellectual Property Office (KIPO), the State Intellectual Property Office of the P.R.C (SIPO) and the United States Patent and Trademark Office (USPTO) launched the patent prosecution highway (PPH) pilot program among the IP5 on January 6, 2014. Its duration was three years, and was scheduled to expire on January 5, 2017.
The five Offices now decide to extend the PPH pilot program for three years, as from January 6, 2017. Related requirements and procedures can be found on the websites of the Offices. (Translated from SIPO Website Chinese Version)
