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.

The surge in AI development has led to a desperate demand for large, high-quality training data. However, real-world data can be expensive to collect, difficult to access, and often subject to strict privacy and regulatory constraints. Synthetic data, which consists of artificially generated records that replicate the statistical properties of real-world data without reproducing specific individuals’ information, provides an appealing solution by generating artificial datasets at scale without relying on identifiable personal information. It combines speed, cost efficiency, and regulatory compliance, making it a sensible alternative for organizations seeking to reduce risks while maintaining data utility. When properly anonymized, synthetic datasets may fall outside the scope of laws such as the EU’s General Data Protection Regulation (GDPR) or Thailand’s Personal Data Protection Act (PDPA), reducing compliance burdens while still supporting high-quality model training. However, relying on synthetic data without rigorous legal due diligence could be a strategic mistake. It replaces one set of known risks (scraping, direct privacy liability) with a new set of complex liabilities. The narrative that synthetic data is a “silver bullet” for privacy and IP compliance is dangerous and could be misleading. While synthetic data addresses data scarcity, it also introduces new legal uncertainties. Legal counsel should anticipate downstream risks arising from compromised data sources. Models trained on unlawfully obtained data may need to be decommissioned, even if their outputs appear lawful. What is synthetic data? Synthetic data refers to artificially generated information created using AI techniques such as deep learning and generative models. Instead of copying real records, it reproduces the statistical patterns and relationships found in the original dataset. Synthetic data generally falls into three categories: Fully synthetic data – Entirely new data points generated from learned patterns. The model studies the structure of the original data and produces records that resemble real-world

Thailand is preparing to offer new tools for intellectual property enforcement as the Electronic Transactions Development Agency (ETDA) recently released for public consultation a draft notification requiring social media platforms to verify user identities and conduct know-your-customer (KYC) checks on advertisers. The draft Notification of the Electronic Transactions Commission on Measures to Prevent Technological Crimes for Social Media Service Providers, which is to be issued under the Emergency Decree on Measures for the Prevention and Suppression of Technological Crimes B.E. 2566 (2023), as amended in 2025, primarily aims to combat online fraud and technology-related crimes. However, its new obligations also provide IP owners with valuable tools to identify anonymous infringers. Key Regulatory Mandates The draft notification imposes several verification requirements on social media platforms operating in Thailand. These requirements also strengthen IP rights holders’ ability to identify anonymous infringers, as platforms must: Verify user identities through registered phone numbers and link all accounts to verifiable identities. Conduct KYC checks on advertisers, including individuals, companies, and any third-party payers. Perform heightened identity checks for high-risk or repeat offenders before publishing advertisements. Promptly remove content flagged by the Anti-Technology Crime Division and prescreen advertisements for prohibited or high-risk content. How IP Owners Can Use This Notification for Enforcement The phone number–based verification requirement enables IP owners to work more effectively with enforcement authorities in tracing individuals or entities responsible for infringing content. The comprehensive advertiser KYC obligations, including mandatory disclosure of third-party payment sources, create a clear audit trail even when bad actors attempt to obscure their identity through intermediaries or shell accounts. This traceability is essential for pursuing damages and dismantling organized counterfeit operations. The ETDA is now considering adjustments to the draft notification after receiving comments during the public consultation period, which ended on February 2, 2026. Following finalization

Tilleke & Gibbins is proud to announce that four litigation cases handled by the firm have been selected among the nine Distinguished Judgment Awards granted by Thailand’s Central Intellectual Property and International Trade Court (IP&IT Court) for the period from October 1, 2024, to August 31, 2025. This recognition highlights the complexity, novelty, and legal significance of these cases, which were chosen based on stringent criteria including new legal issues, high evidentiary volume, and intricate legal arguments. Among these four cases, one was singled out as the “Most Distinguished Judgment” – the landmark trademark squatting case involving the trademark rights of our client, Thailand’s largest state-owned energy conglomerate, and its subsidiary. In this case, the defendants had filed 52 trademark applications mimicking our client’s marks, making it the largest trademark squatting dispute in Thai history. On April 30, 2025, the IP&IT Court ordered the cancellation of multiple infringing trademarks, setting a benchmark for IP enforcement against trademark squatters in Thailand. The other three recognized cases demonstrate Tilleke & Gibbins’ breadth of expertise in IP litigation: Patent infringement and invalidation involving trade secrets misappropriation. Trade dress infringement of a unique packaging. Landmark Luckin Coffee case involving trademark infringement and invalidation. The IP&IT Court handles approximately 200 IP civil litigation cases each year, and our IP litigation team has typically been involved in 25–30% of them, reflecting our dominant role in shaping IP jurisprudence in Thailand.
