From March 1, 2018 European patent applications and registrations can be validated in Cambodia, thereby conferring essentially the same protection as throughout the 38 member states of the European Patent Organization. Validation is made upon request and payment of a 180 Euro validation fee, and only possible for European or international applications filed on or after March 1, 2018.

The validation system is based on an agreement between the President of the European Patent Office and the Cambodian Minister of Industry and Handicraft dated January 23, 2017, ratified by Royal Kram No. NS/RKM/1117/017 and implemented through the declaration (prakas) No. 282 MIX/2017 passed December 8, 2017. Further details are expected from the EPO and the Ministry of Industry and Handicraft in the coming weeks.
