Registering a Trademark and Protecting IP in Thailand: Process, Cost, Refusals and Enforcement

Why Register a Trademark Early

• Thailand is "first to file": trademark rights generally go to whoever files first, not who used it first — if you've used a mark for years but never registered and someone else files, the trouble is yours
• Squatting is common: well-known brands and suddenly-popular shop names are easily filed by locals or competitors, who then demand you rebrand or seek damages
• Registration is your firm footing: a registered trademark is legally protected — you can assert exclusive rights, stop others' use, and rely on it to enforce
• Build brand protection into your plans before opening — see opening a restaurant in Thailand and starting a business in Thailand

The Registration Process: From Search to Certificate

1. Trademark search: first check for identical or similar prior marks and assess registrability to reduce refusal risk
2. Choose classes: select classes by the international classification (Nice) of your goods/services — one mark can cover multiple classes but usually charged separately
3. File the application: submit to the DIP with the mark, applicant details and goods/services list
4. Examination: the office conducts formal and substantive examination and may issue a refusal or request corrections
5. Publication and opposition: once through examination it's published, and others may oppose within a set period
6. Grant and certificate: with no opposition (or opposition failing) it's registered; a trademark has a protection term and is renewable on expiry

The whole process usually takes a while (months to over a year depending on the case), subject to DIP's current examination pace — file early to secure your place.

Roughly How Costs Break Down

• Official fees: charged by application/registration stage and number of classes — more classes cost more
• Agent fees: fees for a trademark agent or lawyer's search, filing, and refusal responses
• Later fees: responding to refusals, oppositions and renewals may be charged separately
• This guide gives no absolute figures (they vary widely by class count and agent) — follow the written quote from an agent/firm and DIP's current fees; budget for multiple classes and brands together

Common Refusal Grounds and Responses

• Similar to a prior mark: the most common — a prior search greatly cuts this risk
• Lacks distinctiveness: overly descriptive, generic, or merely indicating quality/origin may be deemed non-distinctive
• Prohibited elements: national flags, the monarchy, public order and morality and other barred elements
• Response: on receiving a refusal you can argue, amend or submit evidence within the deadline — the quality of a professional's response directly affects the outcome, so don't miss the deadline

What to Do If Squatted or Infringed

• Infringed (someone uses your registered mark): send a lawyer's warning letter, complain to the authorities, and if needed sue to stop the infringement and claim damages; counterfeiting may also be criminal
• Squatted (someone registered your brand first): depending on the case, oppose, seek invalidation, or fight via negotiation/litigation — harder and costlier, which is why registering early beats enforcing later
• For counterfeiting or fraudulent use, see the fraud, police report and rights-protection guide
• Where enforcement means litigation, have a professional lawyer assess the evidence and odds — don't take it on alone

Not Just Trademarks: Other IP

• Patents / petty patents: protect technical inventions and product appearance (design), requiring registration
• Copyright: works (copy, design, software, etc.) generally arise on creation, but keeping evidence of authorship aids enforcement
• Trade secrets: recipes, client lists and the like are protected by NDAs and internal controls
• Owners building brands and products should combine trademark, design and copyright protection — consult a professional on strategy

FAQ

I used the brand name first in Thailand — can someone still register it?

Possibly. Thailand's trademark system is fundamentally "first to file", giving rights to whoever files first, not who used first. If you've used a name for years without registering, in principle another party can file for an identical or similar mark, and once granted may demand you stop using it or even claim damages. Prior use can serve as a defense or opposition ground in some cases, but proof is hard, costly and uncertain. The safest move is to register early rather than gamble — subject to DIP rules and professional advice.

How long and how much does registering a trademark in Thailand take?

It usually takes a while — from filing to grant often months to over a year, depending on examination and whether it's refused or opposed. Costs comprise official fees (by stage and number of classes) plus agent/lawyer fees, rising with more classes and any refusal responses or oppositions. This guide gives no absolute figure — follow the agent's written quote and DIP's current fees. Plan the brands and classes you want to protect and budget them together, file early to secure your place, subject to official rules.

My trademark application was refused — is there any hope?

There's a chance. Refusals commonly cite similarity to a prior mark or lack of distinctiveness; on receiving one you can argue, amend the application or add evidence within the deadline, and a professional's response quality directly affects the result. The key is not missing the response deadline — ignore it and the application lapses. Doing a prior search and assessing registrability greatly cuts refusal odds; if refused, don't panic — promptly have a professional agent assess the response strategy, subject to DIP examination and a lawyer's advice.

I found someone counterfeiting my brand — how do I enforce?

First confirm whether you've registered the trademark — enforcement is strong only with a registered right. Options include a lawyer's warning letter, a complaint to the authorities, and if needed a civil suit to stop the infringement and claim damages; serious counterfeiting may be criminal. Before enforcing, secure evidence (infringing items, sales records) and have a professional lawyer assess the odds and route. Without registration your position is far weaker, which again shows the importance of registering early — subject to professional legal advice.
