Online IP Enforcement in Vietnam: Utilizing Site and Keyword Blocking

Subscribe to Updates
Managing Intellectual Property

The growth of Vietnam’s vibrant digital economy offers tremendous potential but is also a driver of the persistent problem of online intellectual property (IP) infringement. The spectrum of issues faced by IP rights holders runs from copyright piracy on digital services (such as streaming and torrent sites) to the sale of counterfeit goods via e-commerce sites and social platforms to the misuse of rights through misleading use of trademarks. These infringements do not only eat into profits; they damage brand reputation and mislead consumers. As a result, site blocking and keyword blocking have become increasingly important components of the enforcement toolkit available in Vietnam.

Legal Framework for Blocking Actions

Site and keyword blocking in Vietnam is supported by a growing legal framework, particularly following the 2022 amendment to the IP Law. Prior to this, the legal basis for blocking was scattered across various laws, and internet service providers (ISPs) were only obligated to block access to infringing content upon official requests from authorities.

The introduction of Article 198b under the amended IP Law marked a significant shift, establishing a clearer mechanism for rights holders to request site blocking directly. This provision obliges them to act upon valid takedown or blocking requests.

In addition to the IP Law, other key legislation includes the Law on Information Technology, the Law on Cybersecurity, the Law on Advertising, and various decrees. Together, these laws provide a more structured and enforceable basis for blocking actions in Vietnam, though practical enforcement still depends on ISP cooperation and the clarity of the infringement evidence.

Competent Authorities

Previously, rights holders could pursue administrative actions through specialized inspectorates under the Ministry of Science and Technology, the Ministry of Culture, Sports and Tourism, or the Vietnam E-Commerce and Digital Economy Agency (iDEA). However, due to a recent government restructuring, these bodies have been dissolved with their functions transitioning to the Government Inspectorate – potentially impacting enforcement timelines in the near term. Civil disputes, including blocking orders, are handled by the People’s Courts, while criminal cases are referred to the police.

Understanding the Blocking Mechanisms in Practice

To effectively deploy these measures, rights holders need to grasp their practical application. Site blocking acts as a direct blockade, intending to stop internet users residing in Vietnam from accessing certain websites deemed to host infringing content. ISPs are the main operators of these blocks, typically upon receiving a valid request or order. They employ technical methods such as DNS blocking (preventing the website’s name from resolving to an IP address), direct IP address blocking, or filtering specific URLs known to contain infringing content. The goal is plainly to deny entry to the origin of the breach from within the borders.

Keyword blocking targets the discoverability of infringing content or products. The logic is that even if an infringing site exists, making it difficult for users to locate it can help to significantly reduce its impact. This includes taking proactive measures such as requesting search engines like Google, Bing, or local alternative Cốc Cốc to remove or lower the ranking of links leading to infringing materials from search results associated with relevant keywords. It also involves working with online ad platforms such as Google Ads, YouTube, Facebook, and TikTok to prevent advertisements for counterfeit or pirated items from being displayed when users search for, or are targeted by, those specific terms. This approach effectively helps to disrupt the connection between consumer searches and infringing online offers.

Practical Steps

Implementing blocking measures requires a structured, practical approach. The process typically begins with identifying and documenting the infringement. Building and preserving strong evidence—such as conducting a bailiff recordal and, where appropriate, making test purchases—is essential to support any subsequent enforcement actions.

With solid evidence in hand, rights holders must choose the most suitable enforcement channel. This decision depends on many factors, such as the severity of the infringement, the urgency of action, and available resources. One option is to submit takedown notices directly to ISPs, using their internal reporting mechanisms. This approach can yield quick results for clear-cut violations. However, its effectiveness largely depends on the ISP’s cooperation, which can be inconsistent. ISPs may decline to act if the infringement appears debatable or too complex to assess without formal adjudication. In such cases, ISPs typically advise parties to seek resolution through appropriate authorities.

Alternatively, rights holders may file administrative complaints with the relevant authorities. This is often more efficient and cost-effective than litigation, though delays may occur due to the ongoing restructuring of the inspectorates. For e-commerce infringements, complaints can be submitted to iDEA.

Civil litigation is suitable for cases involving significant damages or injunctive relief while criminal action is necessary for serious offenses such as large-scale counterfeiting. However, both routes are time- and resource-intensive, and best reserved for major infringements.

Regardless of the enforcement route, the process typically involves the following:

  • Dossier preparation: Compiling proof of IP ownership, evidence of infringement, and legal authorizations (e.g., power of attorney). Documentation requirements may vary by ISP or authority.
  • Submission: Filing the completed dossier with the appropriate entity.
  • Review and action: ISPs may act quickly if the claim is clear, while the authorities are conducting formal reviews. If infringement is confirmed, they may impose sanctions or order content removal.

Even after enforcement, ongoing market monitoring is essential due to the high risk of repeat violations.

Final Thoughts

While site blocking and keyword blocking are not without challenges—with infringers frequently using tactics such as VPNs, domain hopping, keyword manipulation, and anonymity to evade enforcement—they remain indispensable tools for protecting IP rights in Vietnam’s increasingly digital marketplace. They provide concrete mechanisms to limit access to, and visibility of, infringing content. Site and keyword blocking should be viewed as vital components of a broader enforcement strategy—complemented by platform engagement, administrative actions, and litigation when necessary. Success requires persistence, adaptability, and a proactive approach as infringers’ tactics continue to evolve.

Thailand has introduced a comprehensive overhaul of its tax litigation procedures that will significantly impact how tax disputes are handled. The Regulations for Tax Cases B.E. 2568 (2025) take effect on November 24, 2025, and repeal the prior B.E. 2544 (2001) regulations in full. These regulations support the implementation of the Act on the Establishment of the Tax Court and Tax Case Procedure (No. 3) B.E. 2568 (2025), which expands the Tax Court’s jurisdiction to certain criminal tax matters. Published in the Government Gazette on October 14, 2025, the regulations have been reorganized into three parts covering civil cases, criminal cases, and forms, and are designed to accelerate proceedings, tighten evidentiary discipline, and modernize court operations. Structural Reform and Scope The prior regime governed only civil tax disputes. Under the new framework, the regulations introduce a dedicated chapter for criminal cases alongside updated civil procedures, as the Tax Court now has express authority to adjudicate specified criminal tax offenses. Select mechanisms applied in civil case proceedings, such as electronic communication, recording testimony, and appointing experts, also apply to criminal proceedings mutatis mutandis where they do not conflict with criminal procedure. Civil Cases: Evidence Submission, Deadlines, and Scheduling Parties must submit, together with the witness list, originals of all documentary evidence, media, or electronic data (such as files, USB drives, or CDs), and all physical evidence in the party’s possession. Failure to submit any original within the deadline (see below) results in a loss of the right to adduce that item at trial, subject only to narrow exceptions where submission is impossible due to force majeure or where receipt of the evidence is indispensable to the interests of justice. The practical impact is that parties are now obligated to assemble and verify all original documents and data at the very

AI-generated songs are now making waves in Vietnam on platforms like TikTok, with tracks such as “Say mot doi vi em” quickly gaining popularity and sparking widespread attention. This phenomenon raises a host of legal and ethical questions: Who is the author of these songs? Can they be protected by copyright? Who is responsible if there is an infringement? These questions are becoming increasingly urgent as AI music becomes more mainstream in Vietnam. Copyright Protection for AI-Generated Music in Vietnam Under current Vietnamese law, copyright protection is reserved for works that bear the mark of human creativity. The 2022 amendments to Vietnam’s Intellectual Property Law reaffirm that only works created by humans are eligible for copyright. In practice, if a human meaningfully contributes to the creative process—by providing prompts, making selections, editing, or arranging—their contribution may be protected. However, if a song is generated entirely by AI without significant human input, it is unlikely to qualify for copyright protection. When an AI-generated song does not qualify for copyright protection, the question arises as to whether the person who writes the prompts, edits, or compiles the work can still be considered the owner of an asset under the Vietnamese Civil Code. According to Article 105 of the Civil Code 2015, assets include objects, money, valuable papers, and property rights. While AI-generated music that is not protected by copyright is not considered money or valuable papers, it may be regarded as an object (in the form of a digital file or recording) or as a property right if it can be possessed, used, transferred, or exploited for value. Use of AI-Generated Works Without Copyright Protection If a song is not protected by copyright, does that mean anyone can use it freely? Not necessarily. The absence of copyright does not mean the

The Thai Arbitration Institute (TAI), a division of Thailand’s Office of the Judiciary, has taken a step toward harmonizing the tools available for dispute resolution. On August 8, 2025, the institute formally launched the TAI Mediation Center (TAI-MC). Although the amendments to TAI’s Arbitration Rules that will govern the TAI-MC have not yet been finalized, the framework now under consideration suggests that TAI is positioning itself to become a more attractive venue for commercial dispute resolution. In the regime contemplated under the current version of the amendments, TAI proceedings will adopt an “arbitration-annexed mediation” mechanism—commonly termed the “Med-Arb” model—while preserving the procedural safeguards indispensable to arbitral neutrality. Mediation will be entrusted to a separate, dedicated mediator appointed under the TAI-MC who is precluded from serving on the arbitral tribunal in the same matter. By clearly separating the functions of mediator and arbitrator, the institute eliminates any risk that confidential information disclosed during mediation could influence the adjudicatory outcome if the parties do not settle. Only when all parties subsequently make a request may that same mediator assume arbitral duties in the case. The parties will retain substantial autonomy in selecting the mediator. They may either designate a mediator by mutual consent or invite the TAI-MC to appoint one from its authorized panel. TAI has announced its intention to curate that panel with particular emphasis on commercial expertise and cross-cultural negotiation skills, supplemented by ongoing professional training. Where the parties cannot agree on remuneration, the mediator’s fee will default to a tariff comparable to the TAI-MC’s cost schedule, which under the current version of the amendments will be approximately THB 45,000 for disputes in which the aggregate claims do not exceed THB 10 million, with incremental increases tied to higher claim values. This predictable cost matrix is aimed at enhancing
