Following a joint decision by the China National Intellectual Property Administration (CNIPA) and the Canadian Intellectual Property Office (CIPO), the CNIPA-CIPO Patent Prosecution Highway (PPH) Pilot Program will be extended for another five years, from September 1, 2026, to August 31, 2031. The requirements and procedures for filing PPH requests with the two offices under the pilot program will remain unchanged.

PPH is a fast-track patent examination procedure established between patent offices of different countries or regions, enabling these offices to accelerate the examination process through work sharing. Since the launch of its first PPH pilot program in November 2011, CNIPA has established PPH cooperation mechanisms with patent offices in 38 countries or regions, providing effective support for Chinese applicants seeking faster acquisition of patent rights for their overseas applications.(Translated from CNIPA Website Chinese Version)
