Trademark registration in Cambodia
Cambodia is first-to-file, and it asks something most of the region doesn't: an affidavit of use a few years in, or the mark comes off the register. We search, file with the DIPR through a local agent, and keep that calendar so the mark stays yours.
Why register
What a registered mark gets you in Cambodia
Cambodia is first-to-file: ownership goes to whoever registers, not whoever used the name first, so the filing date decides everything. In a fast-growing frontier market that is exactly where brands get taken early. Here is what the certificate gives you once it's yours.
The exclusive right to your name
Registration gives you the exclusive right to use the mark for your registered goods and services across Cambodia, and the legal standing to stop anyone else using it or anything confusingly close: competitors, copycats, and the distributor who decides the brand should be his.
The enforcement toolkit
Customs recordation against counterfeit shipments, and civil and criminal actions against infringers, all run on the certificate. Cambodia's enforcement is younger than its neighbors', which makes a registration that puts you first in line worth more, not less. With it, you are enforcing. Without it, you are negotiating.
An asset, not just a defense
A registered mark can be licensed to your distributor, franchised, or sold outright, and it's what acquirers and investors look for when they price your Cambodian business. At roughly USD 105 per class for ten years of protection, renewable forever, it's the cheapest asset you'll ever put on the balance sheet, in a market where getting in early is the whole game.
What can be registered
Almost anything that identifies you, if it's distinctive.
A registrable mark identifies your business rather than describing the product. Generic and purely descriptive terms are refused, and so are marks confusingly similar to existing registrations in your classes.
Word marksBrand names, company names, taglines, and letter or number marks, the most common filing.
Logos & devicesVisual symbols and graphic elements, registered as you use them.
Combined marksWords and graphics together, protecting the lock-up as a whole.
Shapes & 3D marksThe form of a product or its packaging, provided the shape is not functional.
Color marksSpecific colors or combinations, registrable where they are distinctive and clearly represented.
Trade names & collective marksTrade names and collective marks are protectable too; Cambodia registers visible signs, so sounds and scents generally fall outside.
Every application names the goods and services it covers, grouped under the Nice Classification's 45 classes. Since 2023 Cambodia requires a mark covering more than one class to be filed as a single multi-class application, so your whole specification travels together. We map your products to the right classes and draft the specification as part of the search.
The process
How registration works
Five stages with the DIPR, with the publication and opposition after the mark is accepted. Plan around six to twelve months from filing to certificate when nothing is contested, and the maintenance clock that most owners overlook starts the day it issues.
1
Search before filingDays
We search the DIPR's records and the Madrid designations for identical and confusingly similar marks in your classes, including Khmer transliterations where the mark is in another script. If the mark has a problem, you find out now, for the cost of a search, rather than months in.
2
Filing through a local agentDays
Foreign applicants without a presence in Cambodia must file through a registered Cambodian trademark agent, which the law requires; we act as yours under a signed power of attorney. The application carries the mark, the applicant details, and the full multi-class specification in one filing.
3
ExaminationMonths
The DIPR examines formality and substance: distinctiveness, and conflicts with earlier marks. A provisional refusal is answered within 60 days, extendable by 45 on request, and we draft the response. Once the examiner is satisfied, the registration fee falls due and the mark proceeds to grant.
4
Registration and publication90-day window
Cambodia does this in an order that surprises people: the mark is registered and the certificate issues, then it is published in the Official Gazette, opening a 90-day window in which a third party may oppose. Oppositions are uncommon here, partly because the gazette has historically been hard to access, and we watch the window either way.
5
The certificate, and a clock you must diarizeFrom day one
The certificate gives you ten years of protection from the filing date, renewable indefinitely. It also starts a deadline most owners never record, and missing it costs the mark outright. That is the part of this page worth reading twice.
The checklist
Key requirements for trademark registration in Cambodia
The documents and details the DIPR needs before the application can be filed. The list is short, and most clients send everything in one email.
- A clear representation of the mark. The logo file in high resolution, or the word mark exactly as you use it; marks in another script travel with their Khmer transliteration.
- What it covers. Your products or services, described in your own words; we map them to the Nice classes and draft the single multi-class specification.
- Applicant details. The full legal name and address of the person or company that will own the mark.
- A signed power of attorney. Foreign applicants without a presence in Cambodia file through a registered local agent; the power of attorney appoints us as yours, and we send it ready to sign.
- Priority documents, only if applicable. Where you're claiming priority from an application filed abroad within the last six months.
Keeping it alive
Registration is the start. The affidavit of use keeps it alive
Cambodia asks something most of the region does not: a sworn affidavit, years after registration, confirming you are using the mark or explaining why not. Miss it and the DIPR removes the mark from the register. No dispute, no warning letter, just a missed form. This is where foreign-owned Cambodian marks die.
The 5th-year affidavitAn affidavit of use or non-use, filed within one year after the fifth anniversary of registration. Since the Ministry of Commerce's 2023 announcement, missing it means the mark is struck from the register, and the rule applies to Madrid registrations designating Cambodia just as it does to national ones.
After every renewalThe same affidavit falls due again within one year after the fifth anniversary of each renewal, so the obligation repeats for the life of the mark.
Five years of non-useSeparately, a mark unused for five continuous years is exposed to a third-party cancellation action, which is why the affidavit accepts a documented explanation of non-use rather than forcing a false claim.
Missed renewalsProtection runs ten years from the filing date, renewable within the six months before expiry, with a six-month grace period after at a surcharge. A lapse opens a gap, and in a first-to-file market, gaps get filed into.
We diarize the affidavit the day the certificate issues, and prepare the evidence with you: invoices, packaging, listings, photographs of the goods on sale here. It is the single most common way foreign-owned Cambodian marks are lost, struck off not for any dispute but for a form nobody remembered was due.
What it costs
The DIPR's official fees come to roughly USD 105 per class, with the grant fee included, so a single-class filing carries one government charge from application to certificate. Emerhub's fee for the search, the filing through a local agent, and the prosecution is quoted on request per class, with provisional refusals, oppositions, the affidavit of use, and renewals quoted as they arise.
Why Emerhub
Filed by the team that's already here.
Already on the ground
The same Phnom Penh team that handles incorporations, licensing, and tax files your trademark, through a registered local agent. Most marks ride alongside a market entry, and the timing between the two is part of the advice.
A straight answer before you spend
If the search shows your mark is weak, descriptive, or already taken, we tell you before you pay filing fees, with options: adjust the mark, add distinctive elements, or challenge what's blocking you.
We keep it alive
Many providers file and disappear, which is dangerous in Cambodia precisely because of the affidavit: the mark that registers cleanly is struck off five years later for a form nobody tracked. Ours comes with that calendar built in.
Common questions
Cambodia trademark FAQs
Specific questions about registering and keeping a mark in Cambodia.
Does registering my company protect my brand name?
No. The company registered with the Ministry of Commerce only stops someone from registering an identical company name; it gives no trademark rights. Your brand needs its own DIPR registration, and until it has one, anyone can file for it, including your distributor.
Do I have to prove I'm using the mark?
Yes, and this is Cambodia's defining requirement. You must file an affidavit of use or non-use within one year after the fifth anniversary of registration, and again within a year of the fifth anniversary of every renewal. Since the Ministry of Commerce's 2023 announcement, missing it means the mark is removed from the register, and the rule reaches Madrid registrations too. The affidavit accepts a documented explanation of non-use, so the honest answer is always available, but the deadline is not optional. We track it from the day the certificate issues.
How long does registration take?
Around six to twelve months from filing to certificate when nothing is contested: examination, then acceptance and the registration fee, then the certificate and gazette publication. A provisional refusal or an opposition extends that. Protection runs from the filing date once registered.
What does it cost?
Official fees come to roughly USD 105 per class, with the grant fee included. Our fee covers the search, the filing through a local agent, and the prosecution to certificate, quoted per class; provisional refusals, the affidavit of use, and renewals are quoted as they arise. Schedule a call with your mark and product list and we'll give you the exact figure.
Someone already registered my brand. What can I do?
It depends where their filing stands. If it's within the 90-day window after publication, we oppose. If it's registered, the strongest route is often a non-use cancellation, since many squatted marks are never used, and Cambodia's own affidavit regime makes that vulnerability easy to surface once five years pass. Bad-faith and better-right cancellations and a negotiated purchase are also on the table. We assess which fits before you spend on any of them.
Do I need a local agent to register?
Foreign applicants without a residence or representative office in Cambodia are required to file through a registered Cambodian trademark agent; it's a statutory rule, not a preference. Our service includes the agent and the power of attorney that appoints them, and a local address so official notices, including the ones that matter for the affidavit, reach people who act on them.
How many classes can one application cover?
As many as your brand needs. Since 2023 Cambodia requires a mark covering more than one class to be filed as a single multi-class application, where previously you filed a separate application per class. The official fee is still counted per class, but the filing, the certificate, and the affidavit all travel as one.
What happens if someone opposes my application?
Opposition runs after acceptance: the mark is published in the Official Gazette and a third party has 90 days to file a notice of opposition, to which you respond with a counter-statement and supporting evidence. Oppositions are uncommon in Cambodia, but a contested case adds time, and we handle the defense and tell you honestly when settling beats fighting.
Can I use the Madrid System instead of filing locally?
Yes; Cambodia has been a Madrid member since 2015, so you can designate it in an international application. One warning that catches international portfolios: the affidavit of use applies to Madrid registrations designating Cambodia exactly as it does to national ones, and it has to be filed locally. A designation without someone tracking that deadline is a mark waiting to be struck off. For a Cambodia-only filing, the national route is usually simpler.
How does renewal work?
The registration renews every ten years, counted from the filing date. The renewal files within the six months before expiry, with a six-month grace period after it at a surcharge. And the affidavit clock resets: a fresh affidavit of use falls due within a year of the fifth anniversary of the renewal. We calendar both the day the certificate issues.
