Vietnam: After Eight Years, Novartis Patent Case Ends in Positive Result

Managing Intellectual Property

A Resounding Victory

The last days of October brought some excitement for one of the leading pharmaceutical companies in the world, Novartis, when its patent litigation case in Vietnam against a local generic manufacturer, which had stretched over more than eight years, finally came to an end.

The background of this case is quite simple. Novartis was the owner of a patent protecting the active ingredient vildagliptin, which was commercialized through its Galvus® product, a medicine used to treat type 2 diabetes. In 2015, the company found that a drug manufacturer in Vietnam’s Binh Duong province on the outskirts of Ho Chi Minh City was producing a medicinal product containing the vildagliptin active ingredient—an infringement of its patent. Novartis first submitted a request to the Ministry of Science and Technology (MOST) to apply administrative sanctions on this infringer.

Subsequently, the MOST Inspectorate concluded in July 2015 that the defendant had committed patent infringement and ordered them to stop producing the infringing drugs and recall them from the market. However, the defendant did not comply with the conclusion, and sought an appeal while it continued to produce the infringing medicine.

Realizing that administrative sanctions were not strict enough to deter the defendant, Novartis continued to protect its legitimate rights and interests by initiating a lawsuit at the provincial court where the defendant was headquartered, Binh Duong. Novartis claimed that the defendant had infringed the patent and requesting the defendant to compensate for damages at the highest level allowed by law, pay attorney fees, and publicly apologize to Novartis in specialized newspapers. This began a long journey full of challenges that finally ended with the second appellate judgment declared by the High People’s Court of Ho Chi Minh City on October 17, 2023. The court accepted all claims raised by the plaintiff, Novartis, that were declared by the first-instance court on April 20, 2023 by rejecting the defendant’s appeal against the first-instance judgment. Previously, at the hearing, the People’s Procuracy also requested the court to deny the defendant’s appeal.

On its winding course to this conclusion, the case had a first-instance judgment that was annulled by the High People’s Court on July 24, 2020, and transferred to the People’s Court of Binh Duong for re-trial. The results of the two trials, however, were the same, with all claims raised by the plaintiff accepted by the People’s Court of Binh Duong. The patent also expired on December 9, 2019, while the case was in progress, but the manufacturer had been infringing the patent while it was still alive.

In the long process of the trial, a series of fundamental issues were raised that the court was both responsible for settling and had the opportunity to settle. This included determining that the authority of the Drug Administration of Vietnam was not related to the patent protection. In other words, a registrant for drug marketing authorization is subject to and must comply with the laws and regulations on patents with respect to the drug for which it has applied for registration to bring to market.

The court also had an opportunity to reject all claims from the defendant that the court was required to consider and collect opinions and evidence from the patent issuance process in other countries, such as the U.S. This was because, as confirmed by the IP Office of Vietnam in an official document, a clear and obvious principle that nonetheless still needed to be reaffirmed in specific cases is that patents granted in Vietnam have an independent and territorial examination process; therefore, they are not dependent on any other IP agencies in the world in any respect.

In this case, the court also settled many matters relating to the significance, role, form of solicitation and use of assessment conclusions (expert opinions) conducted by specialized agencies. In general, assessment conclusions are still decisive evidence for cases, but they must be carried out properly to be used during the case settlement by the courts.

Good Signals Sent

While the courtroom at the High People’s Court was not crowded during the hearing, the final award of the case still managed to attract a great deal of attention. Drug traders and manufacturers in Vietnam seem to understand now that they face huge risks and losses if they are not careful about legal aspects relating to IP rights. Patent owners also see in this case a very encouraging result because although it took a long time, with limitations in terms of enforcement and qualifications of specialized agencies, both the first-instance court and the appellate court issued convincing judgments in the direction of protecting the legitimate rights and interests of patent owners.

While state management agencies such as the Drug Administration of Vietnam, health departments and hospitals were not directly involved in the case, they also have recognized that IP issues must now always be carefully considered in the process of state management, such as in bidding packages for generic drugs. Vietnam’s project to establish a specialized IP court, which is expected to be submitted to the National Assembly for adoption within the next two years, should further contribute to more effective enforcement in similar cases.

At the very least, the positive results from the Novartis case should give IP owners additional confidence that their future cases will not take eight years to reach a conclusion!

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

Over the first half of 2025, the government of Vietnam has implemented a comprehensive suite of legislative reforms that significantly impact the country’s intellectual property (IP) framework. These amendments, most of which took effect on 1 July 2025, span the criminal, civil, administrative, and judicial sectors, and are part of a broader initiative to modernize Vietnam’s legal infrastructure, strengthen enforcement mechanisms, and harmonize domestic regulations with international standards. A summary of the key legislative changes and their potential implications for IP protection and enforcement across Vietnam is provided below. Criminal Code: Stricter penalties Under the 2025 amendments to Vietnam’s Criminal Code, penalties for offenses involving the manufacturing and trading of counterfeit goods have been significantly escalated. Individuals convicted of such violations now face fines ranging from VND 200 million to VND 2 billion (approximately USD 7,700 to USD 77,000; up from VND 100 million to VND 1 billion). For corporate entities, the penalties are even more severe, with fines ranging from VND 2 billion to VND 40 billion (roughly USD 77,000 to USD 1.54 million; up from VND 1 billion to VND 20 billion). These heightened penalties reflect the government’s intensified efforts to deter counterfeit-related crimes and protect consumer rights. Law on Handling Administrative Violations: Extended statute of limitations and application of electronic procedure The statute of limitations for addressing administrative violations in the IP sector is still two years. However, in cases where such violations are referred by procedural authorities, this period is extended by one year. The time taken by these authorities to process the case is now included within the overall limitation period. In addition, the Law on Handling Administrative Violations facilitates the use of electronic procedures, provided that the necessary infrastructure, technical systems, and information conditions are in place. Specifically, enforcement authorities are now permitted

In cross-border disputes, a recurring concern for claimants is whether they can protect respondents’ assets located in jurisdictions other than the seat of arbitration. This article explores whether Thai courts can issue interim measures, such as freezing orders, under Section 16 of the Thai Arbitration Act (2002) to support an arbitration seated outside of Thailand. Requesting Interim Measures Section 16 provides that a party to an arbitration agreement may request that the court impose interim measures, either before or during arbitral proceedings. If the court determines that it would have been able to impose such measures had the proceedings been conducted in court, it may proceed as requested. Notably, Section 16 does not limit its application to arbitrations seated in Thailand. It simply refers to “a party to an arbitration agreement,” which arguably includes both domestic and international arbitrations. Further, it allows for applications even before arbitration is commenced, provided that the arbitration is initiated within thirty days from the issuance of the order (or other period the court prescribes). A Hypothetical Scenario Consider the following scenario: Company A, incorporated in the Netherlands, and Company B, incorporated in the Cayman Islands, have entered into a contract containing a clause requiring arbitration at the Singapore International Arbitration Center (SIAC). A dispute arises, and Company A commences arbitration at SIAC. Company B holds significant assets in Thailand, such as bank accounts or real estate. Concerned that Company B might dispose of its assets before an award is rendered, Company A applies to the Thai court seeking a freezing order over those assets. Can the Thai court issue such an interim measure? The answer is not straightforward. Thai law is silent regarding whether Section 16 applies to arbitrations seated outside Thailand, leaving the door open for argument. Some academic sources suggest that

Distinctiveness is a fundamental requirement for a trademark’s registration and protection under Thai law. The Thai courts typically assess distinctiveness based on a mark’s inherent characteristics rather than its use, as proving acquired distinctiveness through use requires substantial evidence, including the duration of use, extent of distribution and promotional efforts. However, the Intellectual Property and International Trade Court (IP & IT Court) has recently ruled that the figurative mark WEPLAY had acquired distinctiveness through use – an uncommon ruling under Thai trademark law. Subsequently, the Court of Appeal for Specialised Cases affirmed the mark’s inherent distinctiveness based on a holistic assessment of its components. This article discusses the criteria for proving both inherent and acquired distinctiveness, offering examples from both courts to provide valuable insights into case preparation and understanding of how the courts assess distinctiveness. Background In 2017 the plaintiff filed a trademark application for the mark depicted below for goods in Class 28, including toy building blocks: The registrar rejected the application on the grounds of non-distinctiveness under Section 7 of the Trademark Act. The plaintiff appealed to the Board of Trademarks, which considered that, when the term ‘weplay’ is used for goods in Class 28, it is descriptive of the nature of the goods applied for as “playthings”. Therefore, ‘weplay’ was deemed nondistinctive under Section 7, Paragraph 2(2) of the Trademark Act. IP & IT Court decision In 2024 the IP & IT Court ruled that the term ‘weplay’ is not a coined or invented word; instead, it is a combination of ‘we’ and ‘play’, conveying the meaning of ‘we play’. When the term is used for goods in Class 28, it describes the nature of the goods as “playthings”. Consequently, the mark was deemed non-distinctive. However, the court considered the evidence presented by the plaintiff,
