Registration of Chinese Patents in Cambodia

Following the signature of a “Memorandum of Understanding on the Registration of Patents of the People’s Republic of China in the Kingdom of Cambodia Between the State Intellectual Property Office of the People’s Republic of China (SIPO) and the Ministry of Industry and Handicraft of the Kingdom of Cambodia (MIH)” on 29 March 2018, it is now possible for owners of patents granted in China (including patents granted on the basis of PCT applications) to register their Chinese patents in Cambodia. 

Under this arrangement, the MIH will check the necessary application materials without the need to conduct a substantive review, before registering a Chinese patent in Cambodia.  The Chinese patent registered in Cambodia will be treated the same as a patent granted under the Cambodia Law on Patents, Utility Models Certificates and Industrial Designs dated 22 January 2003 and its subsequent amendment dated 22 November 2017, and its protection in Cambodia will last for the same length of time as it will do in China.  This arrangement is retroactive as it is possible to register in Cambodia any patent granted in China that was applied for after 22 January 2003, provided that it remains valid.

Please note that the above-mentioned possibility will not apply to utility models or industrial designs.
