On July 25, 2016, a new Prakas (declaration) on Registration of Singapore Patent in Cambodia was enacted by the Ministry of Industry and Handicraft. The declaration sets forth procedures and documents required for re-registering a Singapore patent in Cambodia. The declaration and a request form are found here (in Khmer).
In order to register, the applicant must have first been granted a patent Singapore. The Singaporean patent must be in-force at the time of filing a request for registration in Cambodia. In addition, the patent must have a filing date on or after February 11, 2003.
Although, a certified copy of the Certificate of Grant of Singapore patent is required to be submitted, the Registrar still examines based on the Patent Law and its related declaration. The request must be made to the Department of Industrial Property of the Ministry of Industry and Handicraft, and accompanied by a payment of the filing fee, a certified copy certificate of grant of the Singaporean patent, a certified copy of final specifications, a copy of abstract and a copy of original notarized POA if a local patent agent is appointed.
Cambodian translations must be submitted to the Patent Office within six months from the date of filing a request for registration. The registration fee and annual fee must be paid within three months from date of Registrar's notification.
Patent rights received from this declaration may not be enforced against any prior rights which already existed before the date of filing a request for registration of Singapore patent in Cambodia. A person who has been using or exploiting that patent in Cambodia may continue to use or exploit it, even though, the Singapore patent has granted by Cambodia Patent Office.
