Trademark Registration Processed
We manage the full registration process: searching for conflicts, drafting the application, filing with the Department of Intellectual Property, and responding to any objections through to certificate issuance. Once registered, your trademark is protected for ten years and renewable indefinitely.

Trademark Registration Overview
A trademark is a sign, word, logo, or design that identifies and distinguishes one business's goods or services from another's, helping consumers recognize where a product or service actually comes from.
Registering one gives you legal grounds to stop others from using a confusingly similar mark. It also protects the trust you've built: once customers associate your mark with a certain level of quality, that association becomes something worth defending. For many businesses, a registered trademark ends up being one of their most valuable assets, and one of the few that appreciates rather than depreciates over time.
What changed: cut the repetition (the original said "protect brand identity," "provide legal protection," and "prevent confusion" as three separate ideas that all point to the same thing), and replaced the vaguer "helps build trust and reputation" with something more concrete about what the trust protection actually does. Also dropped "strengthening market position and supporting long-term growth," that's true of almost any business asset and wasn't saying anything specific to trademarks.
Goods Trademark
- Finished products are classified by their function or purpose. If unclear, compare with similar products in the alphabetical list or classify by raw material.
- Multi-purpose products (e.g., a watch with radio) may be classified by main function.
- Raw or semi-finished materials are classified by substance.
- Parts usable only for one product are classified with that product; multipurpose parts follow the main product principle.
- Packaging (e.g., eyeglass cases) is classified with the product it contains.
Service Trademark
- Services are classified by the nature of business activity or by comparison in the alphabetical list.
- Rental services are classified with the rented goods; leasing resembles rental, but hire-purchase is Class 36.
- Consultancy services are classified by subject matter (e.g., transport Class 39, business Class 35, finance Class 36, beauty Class 44).
- Franchise services are classified with the business type of the franchisor (e.g., legal franchise Class 45).

Commercial advice, not just legal theory
We tell you what is possible, what it will cost and what the practical risk is. If a plan will not work, we say so early rather than billing you to find out.
Clear scope and clear fees
You know what is included, what it costs and who is doing the work before we start. No open-ended hourly surprises.
Continuity from start to finish
The person you speak to at the outset stays with your matter. You are not handed to a junior after the first meeting, and you can reach us when something needs a decision quickly.
SUPPORT FROM START TO FINISH
The Application Process
STEP 1
Trademark Search
1–7 days
A search of the DIP database to check for conflicting marks before filing. Not mandatory, but skipping it is the most common cause of later rejection or opposition.
STEP 2
Filing the Application
Same day
Submitted to the Department of Intellectual Property (DIP) in Thai, specifying the goods or services covered under the relevant Nice Classification classes.
STEP 3
DIP Examination
6–12 months
STEP 4
Publication & Opposition Period
60 days
STEP 5
Registration & Certificate
If uncontested
If no opposition is filed, or an opposition is resolved in your favor, the DIP issues the registration certificate.
Common mistakes and reasons for rejection
Skipping the pre-filing search
A check of the DIP database for conflicts before you file. Most rejections and disputes trace back to skipping this step.
Straying from the DIP's approved class wording
The DIP works from pre-approved wording for each class. Departing from it, even with reasonable-sounding language, tends to trigger an objection.
Missing the opposition response deadline
You have 90 days to respond to an opposition, with no extensions. Miss it and the opposition can succeed by default.
Getting the Power of Attorney formalities wrong
Foreign applicants need a notarised Power of Attorney for their local agent, filed within 90 days of the application. Domestic applicants do not need notarisation at all.
Not weighing the real trade-off in multi-class filing
One application can cover several classes, which saves on fees. The catch is that a problem in a single class can delay or reject the entire application, because classes cannot be split out afterwards.
Missing the renewal deadline
Renew within 90 days of expiry, or within six months with a surcharge. Miss both and the registration lapses.

FAQs
How long does trademark registration take?
Typically 10 to 20 months if uncontested. Examination alone takes 6 to 12 months, and an opposition can add 6 months to 2 years on top of that.
Do I need a Thai agent to register a trademark?
If you're filing from outside Thailand, yes. You'll need to appoint a local agent with a notarized Power of Attorney. Domestic applicants can file without one.
What happens if someone opposes my trademark?
They have 60 days from publication to file. You then have 90 days to respond with a counter-statement, no extensions. An unanswered opposition can succeed by default.
How long does trademark protection last?
10 years from registration, renewable indefinitely. Renewal is due within 90 days of expiry, with a 6-month grace period available at a 20% surcharge.
Can one application cover multiple products or services?
Yes, since a 2016 reform. But a problem in just one class can delay or reject the whole application, since classes can't be split apart once filed.
What's the first step before filing?
A search of the DIP database for conflicting marks. It's not mandatory, but skipping it is the most common cause of rejection or opposition later.
