Experience

Won Thailand’s highest-ever award for damages in an IP case at the Intellectual Property and International Trade Court against infringers of a client’s invention patents, with an award of over THB 106 million (approximately USD 3.5 million), plus interest, on behalf of a world-leading pioneer in the aquaculture industry.
Cooperated with the Department of Special Investigation (DSI) to execute sophisticated raid plans and successfully seized more than 1,000 fully assembled motorcycles worth more than THB 40,000,000 from a motorcycle factory in southern Thailand. The motorcycles were seized under the authority of the Thai Patent Act for the offense of criminal infringement of a well-known Japanese motorcycle company’s design patents.
Won a tremendous victory in one of the most complex patent litigation cases ever presented at the IP&IT Court on behalf of a U.S. multinational glass manufacturer. The case involved a Thai patent comprising various product and process claims in mirror-making technology. Our client was the defendant in a civil action brought by a top Japanese glass mirror maker, alleging infringement of its patent rights. In turn, our client filed a counterclaim asserting that the granted patent is invalid and should be revoked. After more than 30 days of hearings with testimonies of world-class experts from both sides, the Court rendered its judgment completely in favor of our client. The Court declared the plaintiff’s patent invalid and unenforceable.
Successfully defended and reached a favorable settlement on behalf of a large Thai automotive lighting company in patent litigation involving a French company in the same business of automotive lighting and the sale of automotive spare parts.
Advising and working in collaboration with the Software Industry Promotion Agency, a public organization under the Ministry of Information and Communication Technology of Thailand. Advised on IPR-related issues for more than 50 Thai software companies and organized three seminars with more than 150 attendees over the project’s three-year span.
Secured a victory for the top producer of welding electrodes in Thailand against a local infringer in a landmark passing-off case before the Supreme Court of Thailand. The client’s resounding success may be attributed to the defensive strategy of using multiple separate trademark registrations to collectively cover the entire package design.
Represented a top Italian fashion design company in a case before the IP&IT Court. The IP&IT Court cancelled the defendants’ 18 trademarks, awarded a substantial amount of compensation to the client, and issued a permanent injunction prohibiting the defendant from using marks similar to the client’s trademarks and trade name.
Advised a Fortune 500 health care services company and successfully secured its valuable trade secret from possible misappropriation by suspected infringers.
Provided strategic advice on trademark portfolio management and helped to combat several infringing logos on behalf of the world’s largest international coffeehouse chain company.
Advised and assisted a financial services company in protecting its computer software against unauthorized use and dissemination of copyrighted works.
Represented a leading U.K.-based sportswear and football equipment supplier in a civil case against its former Thai distributor. Obtained an Anton Piller order and seized a total of 96,000 counterfeit items that were produced in breach of the defendant’s contract with the client.
Represented multinational companies in complex patent litigation matters in both prosecuting against patent infringement and defending against the alleged use of equivalent technology.

Thailand’s Evolving Website Blocking for IP Protection

In Thailand, the rise in online intellectual property infringement has prompted authorities to strengthen enforcement efforts, including the use of website-blocking orders under Section 20(3) of the Computer Crime Act B.E. 2560 (2017) (CCA). This provision authorizes the Ministry of Digital Economy and Society (MDES), with court approval, to block or remove computer data that constitutes a criminal offence under IP law. Since its implementation, the procedure has undergone several developments, which is an encouraging sign of progress. Website-blocking procedure In practice, website-blocking orders under Section 20(3) of the CCA are primarily used for copyright and trademark infringement. While such orders are legally applicable to patent infringement, their use remains challenging due to the difficulty of proving infringement through administrative procedures. The website-blocking procedure begins when an IP owner identifies online infringing content. For copyright infringement, which is considered a compoundable offence, the IP owner is required to first file a police report with the specialized police unit known as the Economic Crime Suppression Division (ECD) prior to filing the website-blocking application with the Department of Intellectual Property (DIP). For trademark infringement cases, the application can be filed directly with the DIP without a prior police report. The DIP reviews the evidence and, if infringement is confirmed, forwards it to the MDES for further consideration. If the case is deemed valid, the MDES requests a court order to block the infringing website. Once granted, the MDES notifies the internet service providers (ISPs) to block access to the specified website. Website blocking procedure in Thailand Recent advancements in website-blocking actions Seamless collaboration through digital integration. Thailand has made significant progress in digitizing its website-blocking procedures to improve efficiency and transparency. At present, all website-blocking applications and supporting evidence must be submitted in electronic format. These systems have significantly reduced processing

Beyond Takedowns: Tackling Online IP Infringement in Thailand

Online shopping in Thailand is more accessible than ever, with global platforms, local social media shops, and entertainment-driven social commerce enabling instant purchases. However, this convenience comes with rising concerns over digital intellectual property (IP) infringement, including counterfeit goods, pirated content, and unauthorized brand usage. At first glance, online platforms appear to offer quick solutions. Most major e-commerce sites, social media channels, and social commerce platforms provide “notice and takedown” systems, where IP owners can file complaints and request the removal of listings that infringe IP rights, such as trademarks and copyrights. These tools are certainly useful, as seeing a fake product vanish from a platform feels like progress. But the reality is less reassuring. The counterfeit goods themselves remain in warehouses, markets, or shops, ready to be resold. Sellers whose accounts are taken down often return within days under new names or accounts. In other words, a takedown is like cutting weeds without pulling out the roots: they always grow back. While notice and takedown tools are widely available and can be managed internally by most IP owners, their impact is often short-lived. IP owners seeking more effective, lasting protection need to take a more strategic and multilayered approach. The same applies to online piracy. Unauthorized streaming websites that offer free access to movies, TV shows, or sports broadcasts have become widespread in Thailand. To combat this, rightsholders can request website blocking under the Computer Crime Act, through the Ministry of Digital Economy and Society and the courts. Once requests are approved, internet service providers are ordered to block access to infringing sites. Blocking orders can be effective in disrupting large-scale piracy operations, but they also face limitations—pirate sites frequently reappear under new domains. Strategic Protection Whether the infringing material is physical counterfeit goods or intangible streaming content,

AI Model Training and Copyright in Thailand: Key Challenges and Potential Solutions

Artificial intelligence (AI) model training and data scraping are essential processes in the development of modern AI systems. AI model training involves using large datasets to teach machine learning algorithms to recognize patterns, make predictions, or generate new content. Data scraping refers to the automated extraction of information from websites or digital sources, often to assemble the vast datasets required for effective AI training. As these practices become more widespread, questions about the legality of using third-party content—especially copyrighted works—have become increasingly important. In Thailand, the legal landscape for AI developers is shaped primarily by the Copyright Act, which presents unique challenges due to the absence of a fair-use exception. This article examines the copyright-related risks and legal uncertainties facing AI developers under Thailand’s current copyright law and practices, offering strategic guidance for navigating this complex environment. Copyright Risks in AI Scraping and Training Thailand’s Copyright Act does not provide a broad fair use or fair dealing exception, unlike some other jurisdictions, such as the United States. This absence has significant consequences for AI developers: No general defense for AI training: Any use of copyrighted material for AI model training is presumed to be infringing unless a specific, narrow statutory exception applies or explicit permission is obtained from the rights holder. There is no general legal basis for using copyrighted works in AI training without authorization. Increased rights clearance burden: Developers must identify and secure licenses for every copyrighted work included in their training datasets. Given the scale and diversity of data required for effective AI models, this process can be both impractical and costly. Legal ambiguity and litigation risk: The lack of clear statutory guidance or case law leaves developers in a legal gray area. There is no established precedent clarifying whether certain uses of copyrighted material for
