Thailand’s Evolving Website Blocking for IP Protection

Subscribe to Updates
Asia IP

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.

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 times while enhancing transparency and traceability, resulting in more efficient and accountable website-blocking procedures.

For copyright infringement cases, the ECD accepts soft copies of evidence when filing a police report. Similarly, the DIP requires electronic submission of both the website-blocking application and supporting evidence. Once submitted, the DIP reviews the case and forwards it to the WebD platform, a shared digital system developed by the MDES. This platform enables faster processing, centralized tracking and improved coordination between the DIP and MDES.

To further streamline enforcement, Thailand’s Criminal Court has launched a specialized Technology Crime Division to handle online offences, including IP infringement. When requesting a court order to block infringing websites, the MDES files the complaint electronically with this division, significantly accelerating issuance. After the court grants the order, the MDES uses its SUSPEND system, a platform designed to dispatch and track notification letters and court orders, to notify ISPs.

With the adoption of electronic systems across all stages of the procedure mentioned earlier, processing time from the initial filing stage to receiving the court order has significantly improved.

Addressing redirection with dynamic website blocking. Dynamic blocking is a recent judicial development in Thailand, introduced to address the recurring issue of infringing content being quickly moved to new or redirected domains. This approach is particularly relevant given the widespread use of mirror and redirect sites, which have historically reduced the effectiveness of static-blocking orders.

In cases where infringing content is reintroduced through redirected domains, Thailand’s Criminal Court has thoughtfully included provisions for dynamic blocking in its orders. This means that if the same infringing computer data is disseminated again via a new or redirected domain, the original court order can be extended to cover them.

Thanks to this provision, enforcement agencies can rely on the original domain’s court order to request the blocking of redirected domains that host the same infringing content. The request for dynamic blocking can be submitted to the MDES permanent secretary for consideration. Upon approval, the MDES notifies the ISPs to comply with the court order to block access to the redirected domains.

Moving ahead: AI-powered enforcement

In its latest initiative, the MDES has introduced an AI-powered system to enhance the detection of infringing content online. The system automatically scans websites and compiles a report listing suspected infringing URLs, which is then sent to the DIP and IP owners for verification. Once the IP owners confirm the infringement, they can proceed with the website-blocking action.

While the AI-powered system promises to enhance detection, its effectiveness depends on the accuracy of the technology and the capacity of authorities and rights holders to verify and act on the reports. Ongoing monitoring and refinement will be essential to ensure the system’s reliability and to minimize the risks of incorrect detections or unintended blocking. This initiative has recently been implemented, and its effectiveness remains to be seen.

Thailand’s approach to website blocking for IP enforcement has evolved rapidly, with significant improvements in digital integration, judicial innovation and inter-agency collaboration. However, challenges remain, including persistent online infringement, the need for ongoing technological adaptation and the importance of balancing enforcement with due process and transparency.

Vietnam is implementing and developing a broad package of regulatory reforms that could reshape how IP, data, digital platforms, and product authenticity are regulated and enforced. Several of the key measures have been led by the Ministry of Public Security in its legislative and administrative capacity, as part of a broader government effort. The core reform package consists of four key legal instruments: proposed amendments to the Criminal Code, a proposed new Data Security Law, a draft Decree on Product Identification, Authentication and Traceability, and the newly enacted Decree No. 330/2026/ND-CP. These instruments include rules on criminal enforcement, data security, electronic identification, product identification and traceability, administrative violations, and cybersecurity sanctions. Combined, these measures will affect copyright enforcement, industrial property rights, trade secrets, AI training data, product provenance, online takedowns, valuation of counterfeit goods and electronic evidence. It is worth noting that, in addition to strengthening criminal penalties for IP crimes, Vietnam’s emerging regulatory framework increasingly treats infringement, data misuse, product authentication, and platform-enabled violations as interconnected regulatory and enforcement challenges. For rights holders and foreign investors, this could mean stronger tools against counterfeiting and online infringement, but also more compliance obligations around data, traceability, AI, platform controls and government-facing reporting. Expansion of Criminal IP Enforcement Proposed amendments to Article 225 of the Criminal Code would expand criminal copyright exposure beyond reproduction and distribution to cover large-scale commercial public performance and online communication of works, phonograms and video recordings. This is important because piracy is increasingly about streaming, unauthorized communication, and platform access models rather than physical copying. Aggravated copyright infringement could be subject to up to 10 years in prison for individuals and fines of up to VND 6 billion (about USD 228,300) for commercial legal entities. The amended Article 226 would expand criminal industrial property liability beyond

Thailand’s first-to-file trademark system has a serious vulnerability: it lacks both an explicit mechanism for refusing bad-faith registrations and any means of invalidating them in court after the five-year limitation period has expired. While brand owners worldwide confront trademark squatting, Thailand’s statutory silence stands out, particularly in light of AIPPI’s 2017 Resolution Q249, which recommended that every jurisdiction provide clear tools to address bad faith at all stages of the trademark lifecycle. Nearly a decade later, Thailand has yet to act. This article proposes a concrete reform blueprint, drawing on the legislative models of China, the United Kingdom, and the European Union. The Statutory Gap Under the Thai Trademark Act B.E. 2534, no provision expressly authorizes examiners to reject an application on grounds of bad faith. Section 8(10) addresses well-known marks but offers no relief where the targeted mark lacks well-known status. Practitioners have resorted to Section 8(9)—which bars marks “contrary to public order, morality, or public policy”—as a workaround. However, this provision was designed to address the characteristics of the mark itself, not the applicant’s intent. Thai Supreme Court decisions have split on whether it can reach bad-faith conduct, creating persistent legal uncertainty. The gap extends beyond examination. Civil actions to cancel a bad-faith registration must be brought within five years—a deadline that frequently expires before foreign brand owners discover the squatted mark. Cancellation through the Board of Trademarks remains available but is slow, costly, and subject to court appeal, leaving bad-faith registrations in force during protracted proceedings. The system effectively rewards squatters and penalizes legitimate owners. Lessons from International Best Practices Several major jurisdictions have already closed this gap. China’s 2019 amendment to Article 4 of the Trademark Law introduced an absolute ground for refusal: “bad faith trademark applications without intent to use shall be rejected.” Bad

Myanmar’s first-to-file trademark registration regime under the Trademark Law 2019—which became fully operational in April 2023—provides mark owners with enhanced legal protection compared with the country’s former system. Correspondingly, the current system imposes more rigorous statutory requirements for obtaining, maintaining, and enforcing rights in marks. In this first-to-file trademark registration system, however, evidence of use remains particularly significant, as it may establish acquired distinctiveness, support a claim that a mark is well-known, and strengthen the owner’s position in both registration and enforcement proceedings. Accordingly, it can be said that this framework is underpinned by three key concepts: distinctiveness, well-known status, and, importantly, use of the trademark. Trademark Distinctiveness Under the Trademark Law, signs that lack distinctiveness are generally ineligible for mark protection. These signs include generic terms, basic shapes, unstylized single letters or numerals, and signs that merely describe the kind, quality, quantity, intended purpose, value, geographical origin, production time, or other characteristics of the relevant goods or services. However, a mark that would otherwise be refused on distinctiveness or descriptiveness grounds may be registrable if it has acquired distinctiveness through its use prior to the filing date. To show this, the applicant must demonstrate that the mark became distinctive to relevant consumers through continuous, exclusive, and good-faith use in trade within Myanmar. The burden of proving acquired distinctiveness rests with the mark owner. Accordingly, sufficient evidence demonstrating both use of the mark and the level of consumer recognition attained should be prepared in advance. Well-Known Mark Criteria Myanmar’s Trademark Rules, which govern the substantive examination of mark registration applications, establish criteria for determining well-known marks, aligned with international standards. Where an applicant claims well-known status—whether to overcome a refusal on relative grounds or to oppose a third party’s registration—the registrar will assess the claim based on the following

On August 23, 2026, Vietnam’s National Assembly passed Law No. 11/2026/QH16, amending the country’s Customs Law with effect from March 1, 2027. The amendments represent a substantial reform of Vietnam’s customs-based intellectual property enforcement regime. The reforms come amid considerable external pressure. In its 2026 Special 301 review, the US Trade Representative (USTR) designated Vietnam a “priority foreign country,” citing widespread counterfeiting, weak border enforcement, limited ex officio customs powers, and the absence of controls over goods in transit. Vietnam’s legislative response signals a commitment to bringing its border enforcement practices into line with international expectations. For IP rights holders operating in or through Vietnam, the amended law introduces several tools that substantially strengthen enforcement options at the border. Closing the Transit Gap One of the most consequential amendments is the extension of IP-related customs enforcement to goods in transit. Previously, Vietnam’s customs regime applied IP controls only to goods being imported or exported, a gap the USTR had specifically identified as enabling infringing goods to pass through Vietnamese ports with impunity. Vietnam’s geographic position as a logistics hub for Southeast Asia means that substantial volumes of goods transit its ports and free-trade zones. Extending enforcement to cover these shipments brings Vietnam closer to the standard set by the EU’s customs enforcement regulation and addresses a longstanding concern of multinational brand owners whose goods are frequently counterfeited in the region. Strengthened Suspension and Ex Officio Powers The amended law introduces a dual-track suspension mechanism (Article 73(2)). Customs authorities will suspend clearance upon request by an IP rights holder (or authorized representative) who provides evidence of IP ownership, evidence of infringement, and a financial guarantee. Customs can now proactively suspend clearance on an ex officio basis if, during inspection and monitoring, they discover “clear grounds” to suspect that imported, exported,
