Frequently Asked Questions
Trademarks in Cambodia
Covers registration, Madrid System, duration, maintenance, prohibited marks, and infringement penalties under the Law on Marks, Trade Names and Acts of Unfair Competition.
1 / How do I register a trademark in Cambodia?
Trademarks are registered with the Department of Intellectual Property Rights (D/IPR) of the Ministry of Commerce. Foreign applicants must be represented by a licensed Cambodian trademark agent. The application requires the applicant's name and address, a specimen of the mark, the international classification with goods and services specification, and payment of the official filing fee. A notarized power of attorney must be submitted at filing or within two months. The process typically takes nine to twelve months.
2 / How long does a Cambodian trademark application take?
The standard process takes approximately nine to twelve months from filing to certificate, though longer waiting times may occur depending on the nature of the mark and the D/IPR's capacity. Applicants who face serious commercial disadvantage from the delay may request expedited examination in writing, setting out specific reasons for the urgency.
3 / What are the grounds for refusing a trademark application in Cambodia?
A trademark will be refused in Cambodia if it lacks distinctiveness, is contrary to public order or morality, or is likely to mislead the public as to the geographic origin or nature of the goods. Refusal also applies if the mark contains state emblems or official hallmarks without authorization, or if it is identical or confusingly similar to a well-known mark or to a mark already on the register for the same or closely related goods and services. A provisional refusal may be challenged within 60 days.
4 / How long is a Cambodia trademark registration valid, and how is it renewed?
A Cambodian trademark registration is valid for ten years from the filing date and may be renewed for successive ten-year periods indefinitely. A renewal application must be filed within six months before expiry, with a further six-month grace period subject to a surcharge. Critically, an affidavit of use or non-use must also be filed within one year following the fifth anniversary of registration — failure to file this can be grounds for removal of the mark.
5 / What types of marks can be registered as trademarks in Cambodia?
Cambodia registers any visible sign that can distinguish goods or services of one enterprise from those of others. Registerable marks include words, names, letters, numerals, logos, labels, slogans, color combinations (of at least two colors), shapes, three-dimensional signs, and holograms. The shape and packaging of a product are also registerable. Non-visible marks — such as sounds, smells, gestures, and motion — cannot be registered. Single-color marks are excluded.
6 / Can I register a trademark in Cambodia using the Madrid System?
Yes. Cambodia joined the Madrid System for the International Registration of Marks on June 5, 2015. This allows brand owners to file a single international application through their home IP office, designating Cambodia among over 120 member countries. A Prakas issued on November 1, 2016 sets out specific procedures for applications where Cambodia is either the office of origin or the designated state.
7 / What are the penalties for trademark infringement and counterfeiting in Cambodia?
Counterfeiting a registered trademark in Cambodia carries a fine of 1,000,000 to 20,000,000 Riels (approximately USD 250–5,000) and imprisonment from one to five years, or both, with penalties doubled for repeat offenses. Imitation that falls short of counterfeiting is punishable by a fine of 5,000,000 to 10,000,000 Riels and imprisonment of one month to one year. Courts may also order the destruction of infringing goods regardless of whether a conviction is obtained.
Patents in Cambodia
Covers patentable inventions, the application process, patent duration, utility models, and Cambodia's bilateral acceleration programs with Japan, Korea, the US, as well as European and Chinese patent validation.
1 / What inventions can be patented in Cambodia?
Any invention — defined as an idea permitting the practical solution of a specific technological problem — may be patented in Cambodia if it is new, involves an inventive step, and is industrially applicable. Excluded from patentability are scientific theories, business methods, medical treatment and diagnostic methods, pharmaceutical products, plants and animals (other than microorganisms), and plant varieties. Computer software is patentable if it constitutes a qualifying process or product invention.
2 / How do I apply for a patent in Cambodia?
Patent applications are filed in person with the Department of Industrial Property of the Ministry of Industry, Science, Technology and Innovation (MISTI) — e-filing is currently available. The application must be in Khmer and include the invention description, claims, drawings where necessary, and an abstract, accompanied by payment of the official fees (USD 80 for up to 10 claims, plus USD 5 per additional claim). A notarized power of attorney is required if a local patent agent is appointed.
3 / How long is a patent valid in Cambodia?
A Cambodian patent is valid for 20 years from the filing date, subject to payment of annual maintenance fees. Annual fees start in the second year at USD 20 and escalate to USD 890 by year 20. There is a six-month grace period for late payments. If unpaid after the grace period, the patent lapses, though the owner may apply for restoration at any point during the remaining 20-year term by paying a restoration fee plus accumulated late fees.
4 / Can a European patent be validated in Cambodia?
Yes. Cambodia was the first country in Asia to sign a European Patent Validation Agreement, which entered into force on March 1, 2018. Holders of European patent applications (including European PCT applications) filed on or after that date may extend protection to Cambodia. The process requires payment of a EUR 180 validation fee within six months of the EPO search report publication, followed by a formal validation request and Khmer translation of the title, abstract, and claims within three months of grant. Pharmaceutical product patents are excluded.
5 / Can a Chinese patent be re-registered in Cambodia?
Yes. Under a Memorandum of Understanding between Cambodia and China's National Intellectual Property Administration (CNIPA), Chinese invention patents with a filing date after January 22, 2003 may be validated in Cambodia. The system is retrospective, making all qualifying in-force Chinese patents eligible. Design patents and utility models are excluded. The validated patent is valid in Cambodia for the remaining term of the Chinese patent, subject to annual maintenance fees. This is currently the most commonly used route to patent protection in Cambodia.
6 / What is a utility model certificate in Cambodia, and how does it differ from a patent?
A utility model certificate is a shorter-term, lower-threshold alternative to a full patent in Cambodia. Unlike a patent, a utility model only requires the invention to be new and industrially applicable — not to involve an inventive step. A utility model expires after seven years from filing with no possibility of renewal, compared to a patent's 20-year term. Applicants may convert their application between a patent and a utility model once, at any time before grant or refusal.
7 / Can I use a US, Japanese, or Korean patent to accelerate a Cambodian patent application?
Yes. Cambodia has bilateral patent acceleration programs with Japan (CPG program), South Korea (Patent Recognition Program, in force November 2019), and the United States (in force March 2021). Each allows holders of a Cambodian patent application to request accelerated examination based on a granted foreign patent, with MISTI committing to deliver a decision within three months. Cambodia is also party to the ASEAN Patent Examination Co-Operation (ASPEC) program with eight other ASEAN offices, and a Singaporean patent may be directly re-registered in Cambodia.
Industrial Designs in Cambodia
Covers what qualifies as an industrial design, the application and registration process, term and renewal, the Hague System, and infringement penalties under the Law on Patents, Utility Models and Industrial Designs.
1 / What is an industrial design and what does registration protect in Cambodia?
An industrial design in Cambodia is any composition of lines, colors, or three-dimensional form that gives a product a special visual appearance and appeals to the eye. Registration confers the exclusive right to prevent others from making, selling, or importing articles that incorporate the registered design. Protection does not extend to features that exist solely to achieve a technical result, nor to aspects perceived by senses other than sight. Industrial designs are the second most registered form of IP in Cambodia, after trademarks.
2 / How do I register an industrial design in Cambodia?
Applications are filed with the Department of Industrial Property of MISTI. The application must include the applicant's name and contact details, the title and international classification of the design, a description of its novelty and protectable points, and drawings, photographs, or other graphic representations of the article. Foreign applicants must appoint a licensed local agent and provide a notarized power of attorney within two months of filing.
3 / How long does industrial design registration take in Cambodia?
The current processing time is approximately four to six months from filing to receipt of the registration certificate, assuming all requirements are met. This is considerably faster than trademark or patent prosecution. Processing time may be longer depending on the Registrar's workload. Decisions to register or refuse may be appealed to the competent court within three months of the decision.
4 / How long is an industrial design registration valid in Cambodia?
An industrial design registration is valid for five years from the filing date. It may be renewed for two further five-year periods, for a maximum total term of 15 years. Renewal applications must be submitted within six months before expiry, along with the original registration certificate, with a six-month grace period thereafter subject to a surcharge. After the grace period, the registration is deemed abandoned.
5 / Can I register an industrial design in Cambodia through the Hague System?
Yes. Cambodia acceded to the Hague System for the International Registration of Industrial Designs, effective February 25, 2017. The Hague System allows applicants to register up to 100 designs in over 75 territories through a single international application filed with WIPO, significantly simplifying the process and reducing costs for foreign rights holders.
6 / What are the penalties for industrial design infringement in Cambodia?
Infringement of a registered industrial design — the unauthorized making, selling, or importing of articles incorporating the design — is punishable by a fine of 5,000,000 to 20,000,000 Riels (approximately USD 1,250–5,000) and/or imprisonment from one to five years. Penalties are doubled for repeat offenses within five years of a prior conviction. Courts may also grant injunctions to prevent infringement and award damages. A licensee whose license has been recorded with the Registrar may also initiate proceedings if the owner fails to act.
Copyright in Cambodia
Covers protectable works, automatic protection, the Berne Convention accession, duration of economic rights, moral rights, and penalties under the Law on Copyright and Related Rights.
1 / What types of works are protected by copyright in Cambodia?
Cambodian copyright law protects original literary, scientific, artistic, and musical works. This includes books, lectures, dramatic and musical compositions, choreographic works, audiovisual works, paintings, sculptures, photographs, architectural works, maps, computer programs, and handicraft products. Works excluded from protection include laws and official government documents, court decisions, and ideas, methods, concepts, principles, or discoveries — even if expressed or described in a work.
2 / Is copyright registration required in Cambodia?
No. Copyright protection in Cambodia is automatic upon creation of an original work. No registration or deposit is required for protection to arise. However, authors and rights holders may voluntarily deposit their works at the Ministry of Culture and Fine Arts for a filing fee. The primary benefit is evidentiary: the resulting certificate of registration serves as formal proof of ownership and creation date should a dispute arise.
3 / Are foreign works protected by copyright in Cambodia?
Yes. Since Cambodia acceded to the Berne Convention in March 2022, foreign works receive the same copyright protection as works created in Cambodia, without any formalities. Works first published abroad are automatically protected in Cambodia under the national treatment principle, and Cambodian works are correspondingly entitled to Berne Convention protection in all member countries. This accession has retroactive effect, covering existing foreign works that were still within their copyright term.
4 / How long does copyright protection last in Cambodia?
For most works, economic rights last for the life of the author plus 50 years. Anonymous, pseudonymous, collective, audiovisual, and posthumous works are protected for 75 years from the date of publication (or 100 years from creation if not published within 50 years). Performance rights last 50 years from fixation or from the performance date if not fixed. Phonogram rights last 50 years from publication or fixation. Broadcasts are protected for 50 years from the date of broadcasting.
5 / What are the moral rights of authors under Cambodian copyright law?
Under Cambodian copyright law, authors hold three perpetual and inalienable moral rights: the right to decide when and how to disclose their work; the right to be identified as the author; and the right to object to any distortion, mutilation, or modification of the work that would prejudice their honor or reputation. These rights cannot be sold, transferred, or waived, and they cannot be seized. Moral rights survive the author's death and are inherited by their heirs.
6 / What are the penalties for copyright infringement in Cambodia?
Infringement of production and reproduction rights in Cambodia is punishable by six to twelve months imprisonment and/or a fine of 5–25 million Riels (approximately USD 1,250–6,250), with penalties doubled for repeat offenses. Beyond criminal sanctions, copyright holders may petition the court for an injunction, compensation for damages, return of infringing materials and equipment, and recovery of any profits derived from the infringement.
