Today, 28th March 2018, a validation agreement between China’s State Intellectual Property Office (SIPO) and Cambodia has come in force. Under this agreement, it is now possible to validate in Cambodia Chinese patents which are in good order and which have a filing date falling after 22nd January 2003. 


In order to validate a Chinese patent in Cambodia, a certified copy of the parent patent issued by SIPO, along with a certificate of the patent register and a Khmer translation of the patent is required. The eventual Cambodian patent will expire at the same time as the Chinese patent upon which it is based.
