Thailand’s First Judgment to Test E-commerce Platform Liability for IP Infringement

With the growth of technology and internet use, consumers are increasingly shifting toward online shopping. E-commerce platforms have created useful and practical online transactions for products across borders. The number of sellers on e-commerce platforms has also increased significantly in recent years. Naturally, the larger the supply of online products, the greater the risk of possible IP infringement online. While this has made shopping more accessible and convenient for many, it has also created significant opportunities for fraudulent sellers. These fraudulent sellers are often anonymous, and it can be hard to identify them or hold them to account. As a result, some intellectual property (IP) owners have tried to hold e-commerce platforms responsible, raising questions as to what legal liability e-commerce platforms have for content posted by users.

In March 2022, the Central Intellectual Property and International Trade Court (IP&IT Court) issued a landmark judgment finding a world-leading e-commerce platform not liable for a third party’s alleged IP infringement on its platforms.

Contributory infringement

IP can be infringed directly by the person who sells or manufactures the infringing product, or indirectly by a party that encourages or contributes to the infringing act. At present, Thai IP law does not contain any clear provisions on contributory infringement by e-commerce platforms and, until recently, there were no clear court judgments on this issue.

One recent development in this area in Thailand has been the adoption of the Copyright Act (No. 5) B.E. 2565 (2022), which will come into effect on August 23, 2022. This act provides that internet service providers will not be liable for copyright-infringing materials posted by users, provided they comply with certain legal requirements. However, there are currently no equivalent provisions relating to patents, trademarks, or other types of IP rights.

The closest applicable legislation is Section 432 of the Civil and Commercial Code, which provides that a person who instigates or assists in a wrongful act is deemed to be a joint actor and will be jointly bound to compensate for the damage. However the law does not clearly state how this test for contributory infringement should be applied to e-commerce platforms.

In light of the above, in March 2022, the IP&IT Court issued its first judgment on the question of the liability of e-commerce platforms for indirect IP infringement.

Are e-commerce platforms liable for the sale of the IP-infringing goods?

In June 2017, a Thai company filed a patent infringement suit as a plaintiff against Hangzhou Alibaba Advertising Co. Ltd. (Alibaba), alleging that they were liable for the listing of fire-extinguishing balls sold on Alibaba.com, China’s largest international online wholesale marketplace, and AliExpress.com, a global retail marketplace under Alibaba Group, that infringed its patent. This suit also resulted in some negative media coverage against the e-commerce platforms.

Alibaba argued that it did not know or have any reason to know that the products offered for sale on its platform were alleged to have infringed the plaintiff’s patent. As a result, the defendant could not be liable for infringing the plaintiff’s patent.

The buyers must first register an account to order products from the defendant’s websites. When registering an account, buyers enter into an agreement which states that sellers are responsible for any damage caused to the buyer. The plaintiff purchased the fire-extinguishing balls from AliExpress.com website and, as a user of the Alibaba platform, was bound by this agreement. Therefore, the plaintiff’s claim should have been brought against the seller, not the e-commerce platform.

It was the sellers who posted the product listings on alibaba.com and aliexpress.com independently and offered them for sale.Alibaba did not post the disputed product, nor did it have the capacity to control the sale of the product on its online platform. In addition, Alibaba did not know, or have reason to know, that the fire-extinguishing balls infringed the plaintiff’s patent. To combat infringement, Alibaba also maintains a robust notice-and-takedown system and may remove infringing product listings upon receipt of proper notices.

On March 24, 2022, the IP&IT Court issued its judgment in favor of the defendant, concluding that Alibaba was simply an online platform providing services for the buying and sale of the products on its website, and thus the defendant did not infringe the plaintiff’s patent.

Observations

This is a landmark case, as it is the first time the IP&IT Court has addressed the liability of an e-commerce platform for indirect IP infringement. What is particularly notable is the reasoning the court applied. The court used tests that reflect international standards, looking at the e-commerce platform’s actual knowledge of the IP infringement, the party that financially benefited from the IP infringement, and the ability of the e-commerce platform to control the infringing activity. The decision also demonstrates that the court will consider how e-commerce platforms operate in practice and their capacity to control alleged IP-infringing materials on their platform.

As e-commerce and online shopping continue to grow, so too will the number of IP infringement claims brought against platforms. This judgment has the potential to serve as a useful guide for navigating these issues.

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,

Life sciences specialists from Tilleke & Gibbins have updated the firm’s guide to pharmaceutical data exclusivity regulations and practices in Southeast Asia. This guide contains quick-reference information on the availability of data exclusivity protections and limitations in Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam. Developing and launching a new drug on a commercial scale requires an enormous amount of time and investment in research and development (R&D), including pre-clinical testing and clinical trials. When considering the aggregate amount of drug development costs, it is important to recognize that this includes not only the investment in developing new drugs that get approved by a government food and drug regulator and are successfully brought to market, but also the R&D expenditures on a large number of potential pharmaceutical compounds and products that never actually make it to market. In particular, considerable investment is required in order to conduct and produce clinical trial data—to prove safety, efficacy and effectiveness of a new drug—that would warrant marketing approval by the regulatory authority. Such data is proprietary in nature and highly valuable for a research-based pharmaceutical company that develops an original drug. On the other hand, patent law typically confers generic drug manufacturers with the ability to engage in various preparatory activities with a view to obtaining marketing approval for a generic product before the patent for the original drug expires (commonly known as a “Bolar provision”). Since a generic drug maker may submit an application for marketing approval of a generic product before the relevant patent expires, the extent to which the drug originator’s data submitted to the regulatory authority is protected—or in other words, the extent to which the generic company may rely on the drug originator’s previously filed data, which underpins the safety and efficacy of the drug, to support

Vietnam is making notable strides in decentralization, aiming to grant greater autonomy to local government entities to streamline administrative procedures. As part of this effort, the government issued Decree No. 133/2025/ND-CP on decentralization of state management of the Ministry of Science and Technology dated June 12, 2025 (Decree 133). Effective from July 1, 2025, Decree 133 decentralizes and delegates numerous state management functions—including in intellectual property (IP) and technology transfer—to provincial-level People’s Committees (PCs). This reform signals a profound shift in how IP rights are administered and enforced across Vietnam. While this offers new opportunities for IP owners, agents, and innovators, it also introduces additional operational complexities. Impact on IP and Technology Transfer Decree 133 significantly reallocates responsibilities in IP and technology transfer, primarily to provincial-level PCs. Provincial PCs and other provincial authorities are now empowered to handle a wide range of tasks, including but not limited to the following: Issuance of duplicates and reissuance of certificates of registration. Registration of license agreements for the transfer of usage rights for industrial property objects (e.g., trademarks, patents) and recording amendments, extensions, or early terminations of such agreements. Enforcing decisions on compulsory licensing of patent use rights. Evaluation and approval of technology transfer contracts—a key step in facilitating localized technological advancements. Permitting the establishment of foreign-invested scientific organizations and their branches, to encourage foreign direct investment in local R&D and technology development. Approval of provincial-level R&D tasks, aligning with local socio-economic development priorities. Legal Implications The decentralization and delegation brought forth by Decree 133 carry several significant legal implications: Echoing Decree 133, the Intellectual Property Office of Vietnam issued Notification No. 2351/TB-SHTT on June 26, 2025, announcing the cessation of 19 administrative procedures at the national level. Specifically, from July 1, 2025, the IP Office will no longer accept requests related

Three American giants are actively protecting their intellectual property rights against generative AI, as two legal battles commence on both sides of the Atlantic. In the UK, Seattle-based media company Getty Images accuses UK-based Stability AI of multiple IP infringements. In the US, The Walt Disney Company and Universal Studios are teaming up against Midjourney, an AI startup, with their main ground being copyright infringement. Both cases are centered around questions legal minds have been posing since the introduction of generative AI: Is the output of generative AI an infringement? And who is ultimately responsible for the output, the platform or the user? Getty Images v. Stability AI Getty initially filed a claim in the High Court in 2023, which resulted in Stability applying for reverse summary judgment on the grounds that Getty had no real prospect of success, arguing that their operations took place outside the UK. However, the High Court judge hearing the case decided that the claims brought by Getty did have a real prospect of succeeding in court. Despite this, Stability saw a small victory when the court ruled that the representative action brought by Getty would not succeed due to the difficulties in identifying who qualified for the class. The proposed class was comprised of 50,000 rightsholders who alleged their rights were also infringed. Stability was successful in arguing that identifying these individuals would be challenging due to the unclear definition of the class. This current trial is centered around four main grounds: Copyright infringement. Getty accuses Stability of using content that Getty owns or has an exclusive license for when training their model, Stable Diffusion, resulting in the generated output containing substantial parts of that content. Getty is also alleging secondary copyright infringement, arguing that Stability is importing an article into the UK
