Intellectual Property Insights – The construction of the “Silk Road” in the field of patent connecting China and Cambodia

Memorandum of understanding (MOU) on the registration of patent (for patent only, utility model and industrial design, which are not objects of this filing method) between China and Cambodia provides many tactical and visible advantages compared to the other methods, for instance, through national filing system or Patent Cooperation Treaty (PCT)


Firstly, this method is applied for granted and valid patents, therefore, the process is validation of patents rather than the procedure to assess the patentability with full stages (filing application, formality examination, publication, substantive examination, final decision). This filing method is limited only into two main parts: (1) formality examination only, and (2) the acceptance of granting certificate depending on the Chinese patent.


Secondly, the time of procedure is running fast, it will take at least six (06) months from the filing to the completion. Six (06) months in comparison with two (02) years and more of PCT method, the gap between them is considerable.


The cost of two approaches is nearly the same, integrating with the above-mentioned reasons, which leads to the increasing tendency in filing patents through MOU method.


Notably, there is some information regarding the deadline, required documents, namely:


  • The Applicant can submit the request at any time before the expiry date of granted Patent in China;
  • Required documents:
    • Notarized Power of Attorney;
    • Certified copy of Chinese Patent;
    • Certified copy of Chinese Specification with Drawings;
    • English and Khmer translation of the patent documents;
    • Information sheet (including required information: Name and address of Applicant(s)/Inventor(s); Number and filing date of Chinese Application; …).
