Starting October 15, 2024, Cambodia will implement a new penalty for late patent annuity payments and restorations, according to an unofficial announcement from the country’s Department of Industrial Property under the Ministry of Industry, Science, Technology, and Innovation. This new penalty will apply to patents, utility model certificates, and plant variety protection registrations. To avoid additional charges and prevent the abandonment of any pending applications or the lapse of registrations, applicants and registration owners must pay each annuity within the six months before the annuity period starts, or by its due date. If the annuity is not paid by the due date, a grace period of six months is allowed for late payment, with a daily charge of KHR 500 (approximately USD 0.125) per day. If payment is not made within this grace period, the patent will be deemed withdrawn or will lapse. However, the Patent Office can initiate the restoration process within the last six months of the annuity period. This requires a USD 25 restoration fee plus an additional daily charge of USD 0.125 from the start of the grace period until payment is completed. To avoid additional charges and prevent the potential abandonment of applications or registrations, companies and their appointees need to keep track of all annuity due dates for patents, utility model certificates, and plant variety protection registrations and pay all annuities well in advance of the due date. For more details on this penalty, or on any aspect of intellectual property protection in Cambodia, please contact Tilleke & Gibbins at [email protected].

The General Department of Customs and Excise (GDCE) in Cambodia’s Ministry of Economy and Finance launched a trial phase of its Intellectual Property Rights Recordation System (IPRRS) on September 1, 2024. The system compiles necessary information and documents related to intellectual property rights in the country, enabling customs authorities to swiftly access these documents and enhance their ability to identify and intercept potential parallel imports and infringing goods at the border. This will also better facilitate ex-officio actions by customs authorities. The system is currently referred to as being in a “trial phase” to support further amendments or updates to address any potential technical errors that may arise from public use. However, the IPRRS is already fully operational. Types of Recordation Currently, the IPRRS allows two types of recordation: Intellectual property recordation is available for trademarks, geographical indications, copyrights, and related rights that are protected in Cambodia. It allows IP owners, authorized representatives, and legal representatives to record information and documents relating to such rights, including information on possible or potential counterfeit goods, with the GDCE. Recordation will give customs authorities quicker access to the information and enable them to promptly take action against potential counterfeit or infringing goods. Exclusive distributorship recordation is meant to streamline the process that takes place after the Ministry of Commerce issues a notice of the recordation of exclusive rights. Under the current practice, after receiving a copy of a notice of the recordal of an exclusive distributorship issued by the Ministry of Commerce (MOC), the GDCE needs to enter the information into their system manually to enable them to promptly identify or stop potential parallel importation at the border. This reportedly causes delays in border officers’ access to the necessary information. Recordation through the IPRRS, on the other hand, allows local exclusive distributors

Cambodia recently tightened its trademark procedures by restricting the filing of separate single-class applications for a mark covering multiple classes, and tightening the deadline for filing affidavits of use or non-use. The latter requirement is especially consequential for existing registered trademark owners, as disregarding it could result in removal of the registered mark from Cambodia’s trademark registry. Multiple-Class Applications Cambodia’s Ministry of Commerce announced on August 1, 2023, that the Department of Intellectual Property Rights will now only accept a single application for a trademark covering more than one international class. This means that multiple-class applications are mandatory for applications covering more than one class. Previously, trademark applicants were allowed to file separate single-class applications for the same mark covering multiple classes. The new rule, which took effect immediately, aims to reduce unnecessary paperwork and facilitate the trademark registration process. Period for Filing Affidavits of Use or Non-Use On August 11, 2023, the Ministry of Commerce issued a notification stating that trademark registrants who miss the deadline for filing an affidavit of use or non-use will no longer be allowed to file an affidavit after the deadline or at the time of filing the trademark renewal, as had previously been allowed. This is in line with the Sub-Decree Concerning the Filing of an Affidavit of Use or Non-Use, which requires registered trademark owners to file an affidavit of use or non-use of the trademark within one year following the fifth anniversary of the mark’s registration or renewal. Importantly, the notification announces that registered trademarks will be removed from the registry if the trademark owner fails to file an affidavit of the mark’s use or non-use within the required time period. This announcement applies to both domestic registrations and international registrations made under the Madrid Protocol. Although the notification does

Intellectual property experts from Tilleke & Gibbins were engaged by ARISE+ IPR, a regional support program funded by the European Union and implemented by the European Intellectual Property Office, to craft a series of IP enforcement guides for Southeast Asian countries, aimed at raising local awareness of the importance of IP protection. The five-year, EUR 5.5 million ARISE+ IPR program supports regional integration through IP cooperation and aims to upgrade national IP systems for creation, protection, utilization, administration, and enforcement to be in line with international best practices and standards and the strategic objectives of the ASEAN Intellectual Property Rights Action Plan 2016-2025. The guides were developed by Tilleke & Gibbins’ lawyers in cooperation with the IP offices of each participating country, and cover issues related to trademarks, industrial designs, and geographical indications. Each guide was produced in a compact leaflet form in English as well as the local language, and is considered an official publication of the respective national IP office. The guides can be accessed from the ARISE+ IPR site (under “Leaflets, brochures and booklets”), or by clicking on the links below: Cambodia: English | Khmer Indonesia: English | Bahasa Indonesia Thailand: English | Thai Vietnam: English | Vietnamese
