Trademark and IP registration in Thailand — protect your brand before launch
Trademarks in Thailand are registered with the Department of Intellectual Property under the Ministry of Commerce, and protection covers only the classes of goods or services listed in the application. A sound filing starts with a clearance search, choosing classes that match what the business actually sells, and preparing correct corporate or personal documents. Brands expanding abroad can extend protection through the Madrid Protocol. We assist from the initial search and application drafting to status follow-up and any certified translations required.

More frequently asked questions
How many classes should I file in?
It depends on what the business actually sells. A mark is protected only in the classes listed in the application — too few may leave gaps, too many wastes fees. We assess this from your real business activities.
Does a Thai trademark protect me abroad?
No. A Thai registration covers Thailand only. To sell or expand overseas you must file in each country or use the Madrid Protocol to file internationally through the Thai Department of Intellectual Property.
Can I file as an individual before setting up a company?
Yes. Individuals can file in their own name. But if the mark will belong to a future company, plan ownership from the start — transferring the right later involves its own procedure and fees.
What if someone is already using a similar brand?
It depends on whether they have registered and in which classes. If unregistered, you may be able to file first; if registered, options include opposition, cancellation for non-use, or rebranding. Send the details for a case-by-case legal review.
Do foreign documents need certified translation?
Corporate documents or powers of attorney issued abroad usually need translation into Thai and certification in the form the Department accepts. We provide certified translation and notary services in one place.

How Thai trademark registration works in practice
Search before filing to cut refusal risk
Most refused trademark applications fail because the mark is similar to an earlier mark in the same class, or because it simply describes the goods. Before filing, we search the Department of Intellectual Property database by wording, pronunciation and device, then tell you the risk plainly so you can file as is, adjust the mark, or choose a new one.
Choose classes and goods that match the real business
Protection covers only the goods and services listed in the application under the Nice Classification. A list that is too narrow leaves future products unprotected. A list that is too broad, without real use, can increase conflicts with other owners. We ask about your business plans before drafting the list.
After filing: registrar actions and opposition
The registrar may issue an office action requiring amendment or explanation within a statutory deadline. Once examined, the application is published so third parties can oppose it. A registered mark is protected for 10 years from the filing date and can be renewed for further 10-year periods. We record renewal dates for you.
Foreign owners and multi-country protection
Foreign individuals and companies can file in Thailand through a local agent and may claim Paris Convention priority. For protection in several countries, Thailand is a member of the Madrid Protocol, so an international application can be filed through WIPO. We compare national filings with the Madrid route for your case.
