Ownership of Trade Secrets in Thailand

IP Litigator

Thailand’s desire to increase its competitiveness as an investment destination has led to the passage of the Trade Secret Act 2002 (TSA). The TSA is the most recent law on the protection of industrial property rights in the Kingdom and complies with Article 39 of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement). For all its virtues, however, the TSA contains a loophole that may undermine its central goal of preventing unfair competition in Thailand—the TSA does not explicitly vest ownership of a trade secret in a single owner. This loophole is especially problematic where both an employer and an employee claim ownership of a trade secret.

In the course of conducting business, an enterprise may hire a researcher or a team of researchers to create new products or improve existing products. Any trade information, which includes, but is not limited to, formulas, methods, techniques, or processes discovered in the course of research, may be entitled to protection as a trade secret. Akin to other types of intellectual property laws, the TSA grants a negative right to the owner of the trade secret, permitting him or her to exclude others from the act of disclosure, deprivation, or usage of the trade secret. In the event that the right of the trade secret owner is infringed, the owner may bring an infringement action against the alleged infringer in Thailand’s Central Intellectual Property and International Trade Court (IP&IT Court).

In an infringement action, the plaintiff must prove both ownership of the trade secret and that the trade information qualifies as a trade secret. Unlike the Thailand’s Patent Act 1979, the TSA does not require the registration of the trade secret. And, unlike the Copyright Act 1994, the TSA does not include a presumption that the plaintiff is the legitimate owner of the trade secret in dispute. Consequently, the plaintiff is inevitably faced with the prospect of proving his or her ownership of the trade secret.

The TSA identifies the owner of a trade secret by specifying the actions that qualify an entity to claim ownership. To wit, an owner of a trade secret is:

  1. the person who discovers, invents, compiles, or creates the trade information;
  2. the person who has a legitimate interest in the testing result or trade information that is a trade secret; and
  3. the transferee.

If you paused to note the conjunction in this definition, you have read this definition correctly. Ownership in a trade secret can theoretically be vested in multiple entities. For example, an employer would own the trade secret by virtue of having a legitimate interest in the trade information and an employee would also own the trade secret because the employee created the trade information.

Where multiple persons qualifying as owners under provisions (1) and (2) above claim ownership in a trade secret, the TSA appears to be silent on which owner would have superior rights. In this instance, it is appropriate to apply a variation of the canon of construction named in pari materia (upon the same matter or subject), which provides that, in the event of statutory ambiguity, clarification may be derived from reviewing statutes on the same subject matter.

We look first to Thailand’s intellectual property regime. Thailand’s Patent Act 1979 provides that the first right to apply for a patent for an invention made pursuant to an employment or other contract belongs to the employer or the person who commissioned the work, unless otherwise provided in the contract. Thailand’s Copyright Act 1994 provides that the copyright in a work created by an author in the course of employment vests in the author, unless otherwise agreed in writing. The employer, however, is entitled to communicate such work to the public in accordance with the purpose of the employment. Here, the opposing ownership rights may be reconciled by considering the economic realities underlying the creation of the work.

In creating a copyright work, one could say that the employee, who is the author, would have to rely on his or her own creative ideas and effort rather than the information or resources owned by the employer. Therefore, it may be proper to grant the superior ownership right to the employee who created the copyright work as an additional incentive. On the contrary, in creating an invention, the employee would need to significantly rely on the employer to continuously invest in research and development (R&D). Therefore, it is important that the law recognizes the commercial interest of the employer in the invention, by granting the first right to apply for a patent as an incentive to invest in R&D. An argument can be made that a trade secret is more akin to a patent in the nature of the subject matter, as both protections are related to technical or commercial innovation. Further, the employer has a compelling commercial interest in both trade secrets and patented products because both require extensive R&D investment.

Looking further afield for guidance, the European Community has determined that it is preferable to leave the question of ownership of an invention created by an employee open for each nation to answer in accordance with its own laws. The European Patent Convention, therefore, does not specify who has the first right to apply for a patent. The rules relating to the ownership of an invention created by an employee differ greatly among the member states of the European Community. Similarly, copyright laws vary by jurisdiction. The United Kingdom, for example, grants copyright ownership to the employer. This approach is supported by the rationale that the employer is in a better position to derive profit from the copyright work.

While parties (and courts) may look to the intellectual property landscape and the various rationales underlying same to craft their arguments, it is clear that trade secret ownership should not be determined in the context of a dispute or litigation. Instead, employers should enter into a valid written agreement between the employer and the employee to conclusively identify the party who is the only legitimate owner of the trade secret.

Employers can also consider, with able legal counsel, the possibility of taking a transfer of a trade secret.  Section 5 of the TSA provides that “[t]he trade secrets owner is entitled to disclose, deprive of, or use the trade secrets, or license someone else to disclose, deprive of, or use the trade secrets. He may also stipulate any terms and conditions for the maintenance of the secrecy.”

Note, however, that taking rights as transferee may also be fraught with uncertainty. In taking rights as a transferee, the employer must first acknowledge that the employee was the initial owner of the trade secret. While this acknowledgment is necessary to effect a valid transfer of rights (if the employee does not own the trade secret, he or she has nothing to transfer), it will likely undermine any ownership claim subsequently made by the employer. Further, the employer must make certain that the employer is the only recipient of full rights to the trade secret, and that the employee did not and will not transfer his or her rights in the trade secret, or any portion thereof, to any other entity. Finally, as with the agreement establishing first rights in the trade secret, the owner must take care to ensure that the agreement is valid and enforceable.

In sum, until the law is changed to specify who is the first owner of a trade secret, employers’ rights to trade secrets developed by their employees will be open to challenge.  If the ownership of trade secrets is in limbo, businesses may have to confront the problem of protecting industrial property rights or preventing unfair competition in Thailand.

Myanmar’s industrial design registration regime has been steadily gaining momentum since the country officially began accepting applications under the Industrial Design Law of 2019. The Industrial Design Division of Myanmar’s Intellectual Property Department (IPD) has actively advanced examination and registration procedures, and as of March 2026, approximately 300 industrial design applications have been published in the IPD’s publicly accessible database—a meaningful milestone in the development of Myanmar’s emerging intellectual property framework. This figure reflects only published applications; additional filings remain pending and will be published after the conclusion of ongoing examination. Filing Requirements in Practice Compliance with a defined set of mandatory requirements is the foundation for filing a valid design application. These mandatory particulars must be provided at the time of filing in order to establish a filing date. These include the applicant’s and creator’s identifying details, a notarized appointment of representative form, the Locarno Classification of the associated product, and a set of graphic representations of the design across multiple standard views. Applicants must also provide a written description of the design and, where applicable, information relating to any priority claim or request for deferred publication. Filing fees are payable at the time of submission. Beyond these core requirements, applicants typically need to provide supplementary documentation, either at the time of filing or in response to a formality examination. This may include evidence of the applicant’s legal entitlement to the design—particularly where the applicant and creator are different parties—as well as supporting corporate and authorization documents. Where priority rights are claimed, the relevant documents must generally be submitted within three months of the Myanmar filing date, with certified English translations required for any non-English priority applications. The supplementary requirements may vary depending on the nature of the application and the examiner’s requests during the formality examination process.

On March 16, 2026, Vietnam’s Ministry of Public Security released a draft version of a new Decree on the Prevention and Combating of Cybercrime and High-Tech Crime to replace the currently effective Decree 25/2014/ND-CP. In the draft, the ministry has proposed a comprehensive regulatory framework aimed at addressing violations occurring within the cybersecurity domain, including measures related to intellectual property. Acts of Online IP Infringement Article 9 of the draft decree notably introduces specific provisions addressing online intellectual property infringement, with detailed lists of acts considered to constitute infringement in the online environment. Copyright and related rights infringement includes: Uploading or sharing works, performances, sound recordings, video recordings, broadcasts, computer programs, software, research, documents, theses, or other intellectual creations on digital platforms without the consent of the rights holder. Unauthorized livestreaming of copyrighted television programs, sporting events, or artistic performances. Uploading, sharing, storing, transmitting, or providing links to infringing works or digital content via websites, social networks, applications, or digital platforms. Providing or using software, tools, devices, or access codes to circumvent technological protection measures or evade lawful control mechanisms implemented by rights holders. Using artificial intelligence (AI) tools to replicate the ideas or structure of another person’s work without significant new creativity or without proper attribution, thereby causing damage to the original author. Industrial property infringement includes: Manufacturing, trading, advertising, or distributing counterfeit goods bearing counterfeit trademarks, geographical indications, or industrial designs, as well as goods infringing industrial property rights through online platforms. Unauthorized registration, appropriation, or use of domain names, account names, or digital identifiers that create confusion regarding the rights holder or the origin of goods or services.

Against the backdrop of Vietnam’s rapid economic and technological transformation and its ambition to build a knowledge-driven economy, the National Assembly of Vietnam adopted Law on Higher Education No. 125/2025/QH15 on December 10, 2025, The new law took effect on January 1, 2026, replacing Law on Higher Education No. 08/2012/QH13 of 2012 and its subsequent amendments after more than a decade of implementation. The new law reflects a significant policy shift toward enhancing the institutional autonomy of higher education institutions (“HEIs”)—universities and other university-level institutions. By granting broader autonomy, Vietnam aims to enable HEIs to operate more proactively, better respond to market needs, and improve the quality and efficiency of education and research activities. Comprehensive Institutional Autonomy in HEIs The new law marks a significant shift by granting HEIs comprehensive autonomy as a statutory right, within the bounds of the licensed scope of educational operation and the legal framework, rather than a conditional right as provided under the former law. Under the new law, HEIs are empowered to exercise autonomy over their academic expertise, training, scientific research, international cooperation, organizational structure, personnel, finance, and other higher education activities. The expansion of institutional autonomy is also accompanied by a correspondingly strengthened framework of institutional accountability. However, Vietnam maintains a certain degree of control and imposes restrictions on institutional autonomy in sensitive and strategically important areas. These controls and restrictions include limitations on training autonomy in the majors of teacher training, national defense, and security; and restrictions on financial and personnel management autonomy for HEIs under the administration of the Ministry of National Defense and the Ministry of Public Security. New Model for Curriculum Development The new law removes the concept of “opening a training major” and focuses regulation on how training programs are developed and delivered. Under the previous regime,

On December 10, 2025, the National Assembly of Vietnam adopted Law on Vocational Education No. 124/2025/QH15, which took effect on January 1, 2026, replacing Law on Vocational Education No. 74/2014/QH13 of 2014. The new law broadens the categories of institutions eligible to deliver vocational training, introduces vocational upper secondary schools, and shifts governance structures for private institutions from ownership-representative boards of management to stakeholder-based school councils. These reforms aim to diversify training providers, align programs with labor market needs, and create a more flexible, open vocational education ecosystem, offering expanded opportunities for foreign and domestic investors, universities, and enterprises. Some highlights of the new Law on Vocational Education are presented below. Expansion of Vocational Training Levels and Programs In addition to elementary, intermediate, and college—the three levels of vocational training program set out under the 2014 Law on Vocational Education—the new law expands the structure by introducing two new levels: Vocational high school training programs are placed between elementary and intermediate levels, and are aimed at combining upper secondary education with vocational training, expanding options for learners after graduating from the lower secondary level. Other vocational training programs are not specified in detail under the new law, but aim to equip learners with the capability to perform and handle one or several simple tasks of an occupation. Expansion of Vocational Education Providers The new law reclassifies and extends vocational education providers by classifying them into two distinct categories: Vocational education institutions, which include colleges, intermediate schools, and vocational high schools. Establishments participating in vocational education activities, which include vocational education centers, vocational-continuing education centers, continuing education centers, other centers with vocational education functions, enterprises, cooperatives, and higher education institutions. Vocational education providers may provide one vocational training level only, or several/all levels, depending on the type of provider. The
