Vietnam: Does Subsequent Cancellation of a Patent Justify a Retrial?

Managing Intellectual Property

In the Vietnamese judicial system, there are two avenues for reviewing a court’s final judgment. Under the current procedural legislation, if such judgment can be shown to be based on a serious error of law, it can go through the process of cassation, where the judgment will be reviewed and possibly annulled due to the material error in the procedures. If, on the other hand, new evidence or facts are discovered that could have affected the outcome of the case, the case can be retried.

Recently, the Supreme People’s Court applied the procedure of retrial to a 2011 patent infringement case following the cancellation of the patent in question, a decision that could set an interesting precedent for future intellectual property disputes.

In this case, which involved a Vietnamese company’s utility solution patent for a shaped aluminum bar, the People’s Court of Ho Chi Minh City had issued a first-instance judgment in favor of the plaintiff, requesting the defendant to make a public apology and pay damages for its infringement of the patent. The appellate court then denied the defendant’s appeal in a June 2012 decision and upheld the first-instance judgment.

An appellate verdict is considered an effective final judgment and, in principle, closes the process of hearing a case. However, in this case, an unexpected situation arose when the utility solution patent was canceled by the National Office of Intellectual Property (NOIP) seven months later, in January 2013. After the cancellation, the defendant filed a petition requesting the court to review the case under the procedure of retrial.

The Supreme People’s Court ruled, in a 2016 decision that was only recently made public, that the case should be retried. The decision did not provide any analysis or guidance, but it appears that the Supreme People’s Court automatically considered the cancellation of the patent as a “new fact” and thus canceled the entire first-instance judgment as well as the appellate verdict, handing the case back to the first-instance court for retrial.

This decision was unexpected, and raises questions about the proper interpretation of the law. The key issue is whether the subsequent cancellation of the patent in question, which had been fully effective at the time of the first-instance and appellate trials, should be regarded as a “new fact” which the court could rely on to approve a retrial.

Pursuant to Article 304 of the 2004 Civil Procedure Code (which was still valid at the time of the first-instance and appellate trials, as well as the time the retrial was ordered), the grounds for retrying a case must be a newly discovered fact which the court and the involved parties were unaware of when the court issued the judgment or ruling. The term “discover” here would seem to indicate that this fact must have inherently existed at the time of the original trial, and not have occurred subsequently. In this case, however, the parties were not aware of such new fact because the fact did not exist until after the judgment took effect. Nevertheless, the Supreme People’s Court held that the patent cancellation was valid grounds for a retrial.

While the Supreme People’s Court’s decision in this case has not yet been widely discussed, it could end up having a major impact on the settlement of IP cases if it serves as a precedent. Vietnam does not have a system of specialized IP courts; thus, in principle, despite many judges lacking deep legal and technical knowledge in IP, any court can be given jurisdiction over an IP case, whether such case is simple or extremely complicated. It is likely that the courts will give more weight to NOIP invalidation proceedings when settling IP disputes, to avoid potential reversal of the final judgments. Some courts may even stay the infringement proceedings pending the final outcomes of the nullity process before the NOIP, as happened recently in a case before the Binh Duong provincial court involving the infringement of a pharmaceutical patent.

The NOIP, unfortunately, is not known for its timeliness in settling patent cancellations. The process may take years, and in some cases there might never be a final decision. If the courts insist on waiting for cancellation decisions before issuing judgments in IP dispute cases, the plaintiffs may face a very long wait indeed. Further clarification is needed on this matter, and invalidation proceedings at the NOIP should be fast-tracked, to ensure that IP owners’ rights are protected.

For multinational franchisors operating in Thailand, a key risk after franchise termination is that former outlets may continue operating in ways that could easily mislead consumers into believing they remain within the authorized network. To justify such operations, former franchisees often argue that the termination was invalid or ineffective. As a result, these cases are often treated as contractual disputes, making it difficult for franchisors to obtain injunctive relief before a final judgment confirms that the termination was lawful. Franchisors face significant commercial and reputational harm during lengthy proceedings, including consumer confusion, disruption to franchise restructuring, and damage to brand reputation and customer trust. In an encouraging development, the Thai court in a 2025 case responded to the problem of unauthorized post-termination franchise operations by granting interim relief, recognizing broader brand and consumer harm, and awarding substantial damages, highlighting a successful litigation strategy of framing the dispute not merely as a contractual termination issue but as trademark infringement causing ongoing commercial injury. The Subway Case From December 2024 to mid-2025, an unauthorized “Subway®” franchise operation in Thailand attracted substantial public and media attention. Reports and online discussions about unauthorized Subway® stores circulated widely after complaints arose about food quality and customer experience at certain outlets that were allegedly operating after their franchise rights had expired. Because these stores continued to use Subway® trademarks, trade dress, and overall commercial appearance, many consumers were unable to distinguish them from authorized operations, resulting in reputational risks and customer confusion that affected the franchisor’s brand and franchise system in Thailand. Subway treated this matter with the utmost seriousness and moved promptly to protect its brand, franchise system, and customers. It filed a civil action with the IP&IT Court seeking a permanent injunction and damages. During the proceedings, the court granted a preliminary injunction

Laos has significantly broadened its industrial property administrative review framework, most notably by extending it to cover copyright and related rights for the first time. Decision No. 0306/IC on the Administrative Resolution of Disputes Concerning Industrial Property Registration, New Plant Variety Registration, and Copyright and Related Rights Recordation took effect on April 24, 2026, replacing the previous rules from 2023, which had covered only industrial property and new plant variety matters. Decision No. 0306/IC governs how Laos’ Department of Intellectual Property (DIP) and provincial offices handle formal challenges to industrial property registrations and applications. The proceedings covered include oppositions to pending applications, appeals of refused applications, requests for cancellation of existing registrations, and—newly—disputes concerning the recordation and interpretation of copyright and related rights. These administrative proceedings within the DIP are heard by a government-appointed Administrative Dispute Resolution Committee, which functions similarly to the opposition and review boards found in other jurisdictions. Key Changes Decision No. 0306/IC covers four categories of administrative proceedings: Oppositions: Third-party challenges to a pending industrial property application before it is granted. Refusal appeals: Challenges to the DIP’s decision to refuse their application. Cancellation or deletion requests: Applications to invalidate an existing registered right on the grounds that it should not have been granted. Copyright and related rights disputes: Challenges to or interpretations of copyright and related rights recordations, including determinations of whether a work qualifies for copyright protection under Lao law. The most significant development is the committee’s new jurisdiction over copyright matters. The committee is now empowered to resolve disputes concerning copyright and related rights recordation—this includes the authority to determine whether a work qualifies for copyright protection and to interpret the scope of an existing recordation. Parties who believe a competitor has improperly recorded copyright over a work, or who wish to contest

Vietnam’s Decree No. 134/2026/ND‑CP, which took effect on 9 April 2026, plays an important role in detailing and implementing Vietnam’s Intellectual Property (IP) Law in the context of rapid digital transformation and the growing application of artificial intelligence (AI). The new decree provides comprehensive guidance on the application of copyright and related‑rights regulations, addressing key issues such as authorship, ownership, statutory exceptions and limitations, registration procedures, and enforcement mechanisms. Through these measures, Decree 134 seeks to achieve an appropriate balance between safeguarding the legitimate interests of rightsholders and fostering innovation, research, and technological advancement, thereby strengthening the state’s framework for the effective management, protection, and exploitation of intellectual property in the digital and AI‑driven environment. Some notable aspects of Decree 134 are discussed below. Copyright for AI-Created Works Decree 134 provides important guidance on the determination of copyright and related rights in works created with the assistance of AI. Article 5a reaffirms the principle that human creativity remains central to copyright protection, clarifying that copyright or related rights arise only where a human makes a substantial and decisive intellectual contribution, exercises effective control over the creative outcome, and assumes responsibility for the content and its legality. At the same time, the provision confirms that AI is regarded solely as a technological tool rather than a rights‑holding subject, thus ensuring consistency with the fundamental concepts of authorship and ownership under the IP Law. By introducing requirements on transparency, proof of human contribution, and compliance with AI‑specific labelling and technical marking obligations, Decree 134 establishes a clear and enforceable legal framework for the responsible use of AI in creative activities. Lawful Use of Copyrighted Texts and Data Article 37a of Decree 134 sets out the specific conditions under which copyrighted texts and data may be lawfully used for scientific research, experimentation,
