Trademark services

Trademarks are subject to domestic law, which means that trademark owners must register their trademarks in each country where they seek protection and in doing so, comply with national laws trademark registration requirements.
 
Our team of trademark attorneys are here to help you navigate the intricated registration process in Thailand. Here is how we can assist you all steps of the way, including after registration:

Before registration:

Standing out from competitors gives your brand a strong marketing edge while helping avoid costly delays from potential trademark refusals or oppositions. We provide trademark availability searches in Thailand to ensure your mark is unique before filing within 2 to 3 working days.

Before filing, we assess whether your mark might be rejected for being descriptive of the goods or services – e.g., “HEALTHY & FIT” for food supplements or “SPARKLING & FRESH” for beverages.
 
If only part of your mark poses a risk, we will recommend disclaiming the problematic element to avoid delays and extra costs.

Although Thailand follows the Nice classification, the IP Office requires very specific descriptions. Broad terms like “pharmaceutical preparations” or “clothing” won’t be accepted. Your foreign registration list will likely need adjustment for Thailand, to avoid office actions. Our team will review and accurately translate the specification to ensure the registration process will be smooth.

Before filing, we will advise on key technicalities, such as class type, color format, disclaimers and translations.
 
After filing, we will monitor the application at no cost, which may involve forwarding office actions and advising you of the best course of action, report the publication and inform you of the registration deadline.


After registration:

We will monitor your trademarks free of charge, which involve informing you of cancellation petitions and informing you when the renewal fees are due.

To effectively enforce your trademark rights, it is recommended to monitor new trademark applications published in the Trademark Gazette. This would enable you to file an opposition against all potential similar trademarks.

We assist clients in enforcing their trademark rights through strategic action against infringement, counterfeiting, and unauthorized use.
 
Our services include cease-and-desist letters, settlement negotiations, administrative actions, and litigation before the courts.

Leveraging your IP rights might entail licensing or assigning your trademarks.
 
We can assist you in drafting and recording agreements matching your business plans and safeguarding your rights.

Our trademark attorneys regularly represent clients in appeals before the Trademark Board, particularly in cases where trademark applications have been refused due to lack of distinctiveness or similarity to prior marks. Drawing on extensive experience and a solid track record of success, we assist clients in presenting compelling legal and factual arguments to challenge such refusals. This includes demonstrating that a mark has acquired distinctiveness through use in the market, or that it qualifies as a well-known trademark under Thai trademark law.
 
Before initiating an appeal, we provide clients with a realistic assessment of their chances of success, based on legal precedent, evidentiary support, and strategic considerations, always with the client’s best interests in mind. Our team ensures each appeal is strategically framed to maximize the likelihood of overcoming objections.

We represent clients in trademark opposition proceedings, whether initiating an opposition against a conflicting application or defending an application that has been challenged.
 
We work closely with clients to assess the strength of their position before proceeding, offering a realistic, strategic evaluation of potential outcomes based on legal standards and practical considerations. When filing an opposition or a counterstatement, we develop clear and well-supported arguments, supported by evidence where appropriate.

We advise and represent clients in all types of trademark cancellation proceedings in Thailand, whether before the Trademark Board or the Intellectual Property and International Trade Court. Our team handles cancellation petitions based on non-use, better right to the mark, and public interest grounds.
 
Before initiating any action, we provide a realistic assessment of the likelihood of success, considering legal precedent, evidentiary requirements, and our client’s strategic interests. We also defend clients whose marks are subject to cancellation, preparing robust responses and presenting relevant evidence to preserve their rights.

We assist foreign trademark owners in responding to provisional refusals issued by the Thai Department of Intellectual Property under the Madrid System. With experience handling hundreds of such refusals, primarily based on objections to broad or vague specifications, we are well-versed in the local list of acceptable goods and services and the registrar’s evolving practices.
 
Our team acts promptly and efficiently, and we do not hesitate to contact the registrar directly to seek clarification or address any ambiguity in the refusal. This proactive approach allows us to tailor our responses effectively and avoid unnecessary delays or misunderstandings.
 
We handle each matter with close attention to detail and maintain oversight of the application through to registration. Once the mark proceeds to publication and registration, we report these milestones to our clients free of charge. Our goal is to ensure a smooth and predictable process for trademark holders navigating the Thai phase of international applications.

We handle trademark renewals efficiently and reliably, ensuring continuity of protection for your registered rights in Thailand. Our firm maintains a tailor-made internal database to track all relevant deadlines, and we send timely reminders well in advance of each renewal date. This system allows clients to renew their marks without risk of lapse or additional fees due to late action.

We provide comprehensive trademark portfolio management services to help clients protect, maintain, and strategically grow their IP assets in Thailand and abroad. Whether managing a single registration or a large multi-jurisdictional portfolio, we offer clear oversight of deadlines, renewals, assignments, and oppositions, ensuring that all actions are timely and aligned with our clients’ commercial goals.
 
Our internal systems are designed to monitor and track each trademark throughout its lifecycle, supported by customized reporting and reminders. We also advise on filing strategies, brand consolidation, and enforcement priorities to keep portfolios both cost-effective and legally robust.
