Trademark Services
A registered trademark gives your business exclusive rights to use your brand name, logo, or slogan in Thailand. The Department of Intellectual Property (DIP), under the Ministry of Commerce, oversees all trademark matters.
To qualify for registration, your mark must be distinctive and cannot contain restricted elements such as royal emblems, national flags, or marks that are confusingly similar to existing registrations.
Without registration, enforcing your brand rights in Thailand is extremely difficult. A registered trademark allows you to take legal action against infringers, seek court injunctions, and claim damages. Registration also prevents others from registering a confusingly similar mark.

International Protection
Thailand joined the Madrid Protocol in 2017, enabling businesses to extend trademark protection to 130+ countries through a single application. Here is how the two routes compare.
| Coverage | Thailand only |
| Timeline | 12–18 months |
| Filing Language | Thai |
| Protection | 10 years, renewable |
| Cost | Lower per-class fees |
| Best For | Businesses operating only in Thailand |
| Coverage | 130+ countries via one application |
| Timeline | 12–18 months per jurisdiction |
| Filing Language | English, French, or Spanish |
| Protection | 10 years, renewable in all designated countries |
| Cost | Cost-effective for multi-country protection |
| Best For | Businesses expanding internationally |
To file via the Madrid Protocol, you must first have a registered or pending trademark in Thailand (your “basic mark”). Lex Bangkok can help you with both the local filing and the international extension through WIPO.
Copyright Services
Copyright in Thailand automatically protects original works from the moment of creation. However, formal registration with the Department of Intellectual Property provides critical evidence of ownership that strengthens your position in any legal dispute. Protection lasts for the creator’s lifetime plus 50 years.
Source code, mobile applications, SaaS platforms, and database structures are all protectable under Thai copyright law. Essential for tech startups operating in Thailand.
Books, articles, marketing copy, website content, and business documents. Copyright registration helps content creators defend their original work.
Musical compositions, sound recordings, podcasts, and audiovisual content receive automatic protection with registration strengthening enforcement.
Graphic designs, photographs, illustrations, and architectural works. Registration provides proof of ownership for commercial licensing.
Cinematographic works, video content, animations, and streaming media. Important for production companies operating in Southeast Asia.
Video games, e-learning materials, digital publications, and interactive media. Protect your digital assets in Thailand's growing digital economy.
For Software Companies & Content Creators
If you are building software products or creating digital content in Thailand, copyright registration is your first line of defense. We help tech companies register their source code, UI/UX designs, and digital assets. Our team also drafts IP assignment agreements to ensure your company — not individual developers — owns the intellectual property created by your team.
Patent Services
Patents provide exclusive rights to inventions, granting the holder legal protection against unauthorized use, manufacture, or sale. In Thailand, the Department of Intellectual Property oversees patent registration under the Patent Act B.E. 2522. Whether you are protecting a new invention or a product design, patent registration is a critical step for businesses innovating in Thailand.
Invention Patents
Protection: 20 years
Protect new inventions that offer a technical solution to a problem. Covers processes, machines, compositions, and manufactured items. Protection lasts 20 years from the filing date.
Design Patents
Protection: 10 years
Protect the ornamental or aesthetic design of a product, including shape, pattern, or color combinations that give a product a distinctive appearance. Protection lasts 10 years.
Petty Patents
Protection: 6–10 years
A simpler, faster form of protection for minor inventions or innovations that may not meet the full patentability requirements. Useful for incremental improvements. Protection lasts 6 years, extendable to 10.
IP Enforcement
Intellectual property infringement is a serious issue in Thailand, from counterfeit goods to unauthorized use of brand names online. If your IP rights are being violated, there are clear legal steps you can take to protect your business.
We conduct thorough investigations to document infringement, gather evidence, and identify responsible parties. This forms the foundation of any enforcement action.
A formal demand letter is often the first step. Many infringers will stop once they receive a legally worded warning from a licensed attorney, avoiding costly litigation.
When informal resolution fails, we file for court injunctions to immediately stop the infringing activity. Thai courts can issue both temporary and permanent injunctions.
Register your trademark with Thai Customs to intercept counterfeit goods at the border. This is one of the most effective tools for brand owners fighting counterfeits.
We handle takedown requests for e-commerce platforms, social media, and websites selling counterfeit goods or infringing your IP rights in the digital space.
In cases of willful trademark counterfeiting or copyright piracy, Thai law provides for criminal penalties including fines and imprisonment.
