Thailand’s Patent Office Granted Power to Strike-Out Cannabinoid Patents

Subscribe to Updates
Informed Counsel

On January 28, 2019, Thailand’s National Council for Peace and Order issued Order No. 1/2562 (the Order) granting the Department of Intellectual Property (DIP) the right to suspend cannabis-related patent applications on legal grounds. This development is in response to the ongoing legalization of medical cannabis in Thailand, and has raised a number of thought-provoking issues.

The NCPO Order    

The Order, issued under the executive powers granted to the military government under Section 44 of Thailand’s interim constitution, includes the right to “refuse the grant of patent” if it appears that the invention under the application has a commercial application and contains:

a)    cannabis or cannabinoids;
b)    substances having similar structural compounds; or
c)    pharmaceutically acceptable salts, esters or ethers of (a) or (b).

This order empowers the DIP Director-General to reject cannabis-related patent applications, or to request the removal of published applications that have not yet entered into substantive examination, on the grounds that cannabis-related applications are not patentable as they are against public order, morality, public health, or welfare (per Section 9(5) of the Thai Patent Act B.E. 2522 (1979).    

Any affected applicants have a right to appeal to the Board of Patents, under Section 72 of the Thai Patent Act, within 60 days of receiving the cancellation order.

Amendments to the Narcotics Act    

To understand the impact of this order, it is useful to understand its place in the broader context—notably the pending amendments to Thailand’s Narcotics Act (the Amendments) that will partially legalize medical cannabis in Thailand. The Amendments passed the final review stage at the National Legislative Assembly on December 25, 2018, and are currently waiting to be signed into law by the monarch. Once signed, the law will be published in the Royal Gazette, and will become effective shortly after. The practical implementation  of the Amendments (including administrative procedures, application processes, required supporting documents, etc.) will depend on Ministerial Regulations to be issued at an as-yet undetermined time after the law becomes effective.

The Amendments are intended to redress the balance between regulatory control and public health needs, by relaxing regulations to allow medical uses of marijuana (both for treatment and research). It should be noted that the present “legalization” does not result in a complete freedom to use, but a new framework for streamlined licensing under set rules and conditions. Even under the amended Narcotics Act, cannabis will still classified as Category 5 Narcotic, and handling cannabis without a license from the Thai FDA will still be generally unlawful.     

Given the diverse array of national objectives, the Amendments will play a role in determining what qualifies as medical cannabis, who can obtain permission to produce or research it, and how such permission can be sought.

Implications on Patenting   

In the meantime, however, holders of patents relating to cannabis derivatives in other countries have sought to protect their intellectual assets in Thailand before the Amendments come into effect, to ensure that they are safeguarded when they do. This raised the difficult decision of whether to patent something that would, under existing law, potentially be unlawful to use and contrary to “public order and morality.” The Order clarifies this difficult decision by effectively providing the answer—those patents can be refused.    

However, this is far from an absolute ban, and in this context the Order has merely served as the gatekeeper—deciding when to “start the game” on determining patent applications during the period before the Amendments take effect. After the Amendments take effect, the Order prescribes that deliberation of decisions to grant patents will return to normal. The consideration of public order and morality when determining patent applications for cannabis-related inventions will be undertaken based on Section 9(5) of the Patent Act and the Narcotics Act as amended. In other words, medicinal applications for cannabis would be patentable, but recreational applications would not.

Difficulties with the Order and the Amendments   

Arguably, this administrative patent procedure may be viewed as a violation of the World Trade Organization Agreement on Trade-Related Aspects of Intellectual Property Rights Agreement (TRIPS). Section 27.1 of TRIPS states that patent rights shall be available in all fields of tech-    nology. As such, in order to assess whether an invention is contrary to public order or morality, the same criteria must  be applied to all inventions uniformly, regardless of the invention’s field.   

In addition, the public order argument is also troubling. Assuming that the public order justification relates to the narcotic effects of some cannabis derivatives, in determining whether a particular commercial exploitation really is considered to disturb public order and morality, it is important to consider that a single invention may have multiple applications. The simulation or extraction of cannabinoids, in this instance, includes, but it is not limited to, recreational effects, and the non-recreational effects should be considered proportionally.    

Cannabis plants contain a number of active compounds such as THC and CBD—the two most well-known cannabinoids. While THC possesses more psychoactive effects, CBD is prone to having substantial medical benefits. The fact that the cannabinoids possess both therapeutic and recreational effects, however, should not render a method of producing the non-psychoactive compound contrary to public order or morality. Regardless of whether the Amendments have currently come into force, it is incorrect to say that a medicinal application that cannot be applied recreationally, such as an application that produces CBD but cannot produce THC, is against public morality and order.    

In addition, the implications of the Amendments may be different for different parties. Under the Amendments, a licensee for the medical use of cannabis must be a Thai national or a company registered in Thailand, among other restrictions.   

While it cannot be denied that medicalizing cannabis in Thailand will encourage medicinal cannabis research and development in the region, it is important that they are done evenly and without such concerns to ensure that Thailand remains an optimal investment environment.

When Decree No. 186/2026/ND-CP (Decree 186) takes effect on July 15, 2026, it will introduce the most significant reform of Vietnam’s administrative IP enforcement framework since Decree 99/2013/ND-CP was issued in 2013. These changes are expected to make administrative enforcement faster, more accessible, and better suited to the realities of modern IP disputes. Below are the principal reforms and their practical implications for rights holders and enforcement practitioners. The End of Notarization and Consular Legalization Among the most welcome procedural changes is the abolition of the notarization and consular legalization requirement for powers of attorney (POA) submitted in administrative enforcement proceedings. Under the previous regime, foreign rights holders were generally required to execute a POA, then have it notarized and consular legalized (if seeking customs recordal). In practice, this process frequently delayed enforcement by four to eight weeks, often long enough for infringing goods to disappear before authorities could intervene. Decree 186 removes this bottleneck, now requiring only an original or certified copy of the POA. If the document is in a foreign language, a Vietnamese translation is sufficient, provided it is certified by a competent authority or confirmed by the authorized Vietnamese IP representative. Consular legalization and notarization are no longer required. For rights holders, the practical impact is substantial. Administrative enforcement files that previously took weeks to prepare can now be completed in a matter of days, allowing much faster responses in time-sensitive matters such as warehouse raids, border interventions, and trade-fair enforcement. The decree also introduces a useful administrative simplification. Where an original POA has already been submitted to the same enforcement authority and remains valid, applicants may rely on a copy of that earlier submission by identifying the previous case file. This eliminates unnecessary duplication for rights holders pursuing multiple enforcement actions before the same

Recycling, upcycling, and refill-packaging models are now widely promoted as ways to reduce waste, lower carbon emissions, and respond to consumer demand for sustainable products. However, complications arise when these environmentally driven trends intersect with intellectual property law—particularly where reused or altered packaging continues to display third parties’ registered trademarks. Adding to this complexity, Thailand’s draft Sustainable Packaging Management Act aims to introduce new environmental compliance obligations that businesses must navigate alongside existing trademark concerns. Recycling and upcycling packaging may infringe trademark rights, especially in cases not protected by the first-sale doctrine—the principle that a trademark owner’s rights over a particular mark-bearing product end once the owner first sells it. Furthermore, even refill packaging carries legal risk due to specific statutory prohibitions under Thai law. Compounding these challenges, the draft Sustainable Packaging Management Act will impose extended producer responsibility (EPR) obligations on manufacturers and brand owners, requiring them to manage packaging throughout its lifecycle. These overlapping legal frameworks could deter manufacturers from pursuing ESG-aligned business models unless businesses understand how to navigate both trademark and environmental requirements. Under Thai law, this issue remains uncertain because the Trademark Act does not expressly codify the first sale doctrine, also known as the exhaustion of trademark rights. Generally, this doctrine provides that once a trademark owner has lawfully sold goods bearing its trademark, the owner’s right to control further resale of those particular goods is exhausted. The rationale is that the owner has already received commercial benefit from the first authorized sale; therefore, the purchaser should be free to resell or otherwise dispose of the goods. Although the doctrine is not expressly codified in the Trademark Act, Thai courts have recognized it in relation to genuine goods and parallel imports, as seen in a Supreme Court Judgment No. 2817/2543 in which the

Indonesia’s regulation on reporting online intellectual property (IP) infringement provides comprehensive procedural guidance for IP rights holders and their licensees in reporting online infringement complaints. Issued in December 2025 by the Ministry of Law as Regulation No. 47 of 2025 regarding Handling of Intellectual Property Infringement Reports in Electronic Systems, this regulation covers all types of IP rights. It also specifies documentation when reporting infringement, and lays out the procedures for examination, verification, and enforcement actions. Submission of Complaints Complainants may submit reports through the online system of the Directorate General of Intellectual Property (DGIP) or in person at the DGIP office. Complaints may also be filed through an authorized proxy. Under the regulation, complainants are required to provide the following information and documents: Personal details of the complainant; Brief description of the protected work or subject matter (i.e., type of IP and name or address of the infringing website, portal, account, or application, or a link to the location of the infringing content); Complete description of the alleged infringement; Certificate of registration or recordal of the relevant IP; Recordal of IP license agreement, if any; and Other supporting evidence. Verification and Examination Process Upon receiving a complaint, the responsible formality officer may request clarification or additional supporting documents. In the latter case, the complainant must then submit the necessary administrative documents within 14 days of the notification date. Once the documentation is deemed complete and sufficient, the case will be formally registered. Subsequently, the DGIP will establish a verification team to handle online IP violations, which will include the Civil Servant Investigator (PPNS), the Ministry of Communication and Digital Affairs, experts with relevant expertise in IP, and representatives from related associations such as AVISI (Indonesian Video Streaming Association). After examining the report, the team will prepare the Minutes

Customs recordation is an enforcement mechanism in Myanmar that enables intellectual property (IP) rights holders to seek prevention of the cross-border movement of infringing goods. The enactment of Myanmar’s IP laws in 2019 has enabled customs recordation for registered marks and copyrights under the Trademark Law 2019 and the Copyright Law 2019. By contrast, the Patent Law 2019 and the Industrial Design Law 2019 do not provide a practical framework for customs recordation, and accordingly such rights are not subject to the customs recordation regime. Under the Trademark Law 2019, rights holders may apply for customs recordation and may also ask the Customs Department to suspend the release of goods suspected of bearing counterfeit marks. Likewise, the Copyright Law 2019 allows for customs intervention in relation to pirated works. These provisions reflect Myanmar’s gradual alignment with international standards on border measures, although the implementation framework remains at a relatively early stage of development. Customs Recordation Pursuant to the Trademark Law 2019 and the Copyright Law 2019, the relevant authorities have issued customs rules concerning the protection of registered marks and copyrights. In practice, the process generally begins with the submission of an application to the Customs Department together with supporting documentation. This typically includes proof of registration in Myanmar; details of the rights holder, applicant, and any authorized representative; and a comprehensive description of the genuine goods. Product identification materials—such as photographs, packaging samples, and distinguishing features—are particularly important in helping customs officers identify suspected infringing goods. A recordation remains valid for two years from the date of approval. It may be renewed for additional two-year terms, provided that the renewal application is filed within the thirty days prior to expiry for marks and up to thirty days in advance of the expiry date for copyrights, in accordance with
