Brand Owners Maximize ROI Through Criminal IP Proceedings in Thailand

Managing Intellectual Property

For decades, intellectual property rights holders seeking to eliminate counterfeit goods from the Thai market have relied primarily on criminal raid actions to seize infringing products and hold infringers accountable. The deterrent value of this approach is typically threefold: imposing criminal liability on infringers, removing counterfeit goods from circulation, and subjecting violators to imprisonment and fines. However, these outcomes often fall short of fulfilling brand owners’ broader objectives. In many cases, those prosecuted are merely staff or intermediaries rather than the principals orchestrating the infringing operations. Moreover, any fines imposed are remitted to the Thai government—not to the rights holders who have suffered commercial harm and invested substantial resources in investigation and coordination with law enforcement authorities.

As in other jurisdictions worldwide, rights holders seeking monetary compensation for IP infringement in Thailand have traditionally pursued separate civil litigation. Before initiating such proceedings, a brand owner must gather sufficient evidence to establish both the infringement and the resulting damages. Notably, Thai law does not recognize punitive damages; courts award only actual damages proven by the claimant. In the absence of seized infringing goods, the damages awarded in such cases are typically minimal. This all leaves rights holders with limited recourse despite possibly having suffered significant commercial injury.

In 2005, Thailand amended its Criminal Procedure Code to introduce Section 44/1, which enables rights holders to claim damages within criminal proceedings at the Intellectual Property and International Trade Court prior to the evidentiary hearing. In practice, this mechanism allows an injured party to submit a petition for civil damages directly within the criminal case initiated by the public prosecutor.

Historically, rights holders in Thailand have been reluctant to use Section 44/1 because the compensation awarded by courts was often insufficient to justify the effort. However, recent years have seen a notable shift in how Thai courts assess damages in criminal IP proceedings when the injured brand owner files a claim for compensation under Section 44/1. This development offers significant advantages: brand owners can now avoid the burden of parallel civil litigation and recover damages within the same criminal proceedings.

Although this procedural tool has long been available, its practical impact is now more significant than ever.

How One Brand Owner Recovered Damages in a Criminal Prosecution

In a recent matter involving counterfeit consumer goods, the legitimate brand owner engaged Tilleke & Gibbins to conduct a market investigation aimed at tracing the source of infringing products. Beyond identifying retail outlets, the investigation mapped distribution channels, identified upstream suppliers and manufacturers, and gathered documentary and physical evidence sufficient to support criminal enforcement.

Based on the evidence collected, enforcement authorities conducted a raid action. The seized goods were confirmed to be counterfeit, and the police subsequently submitted the investigation file to the public prosecutor, who proceeded with criminal charges.

Once the criminal complaint was formally filed, the brand owner exercised its right under Section 44/1 to submit a petition for damages as the injured party within the same criminal proceedings. The damages claim submitted was structured into three main components:

  • Property damage and lost sales. Calculated based on the official wholesale price of the genuine product in Thailand multiplied by the total number of counterfeit units seized during the raid.
  • Damage to reputation and goodwill. Claimed as a lump-sum amount to reflect the unlawful exploitation of a globally recognized brand, dilution of distinctiveness, consumer confusion, and potential erosion of trust in widely consumed goods.
  • Enforcement and legal costs. Covering investigation expenses and legal fees incurred in tracing the source of counterfeit goods and supporting the raid action, supported by documentary evidence.

In cases involving consumer goods that may pose health or safety risks, Thai courts have shown heightened sensitivity. Likewise, in cases with counterfeit goods relating to products used in daily consumption or personal care, courts recognize not only trademark infringement but also the broader public interest dimension, as these counterfeit goods may endanger consumers and undermine trust in legitimate distribution channels.

In this case, the court rendered its judgment in favor of the brand owner, ordering the defendants to pay approximately half the total damages claimed. The court’s granting of the enforcement costs in full and awarding of a substantial amount for reputational harm was a clear recognition of the commercial and consumer impact of counterfeit goods.

This development signals an increasingly pragmatic and brand-conscious approach by the Thai IP Court, particularly in cases involving widely consumed products.

Strategic Implications for Brand Owners

This case illustrates how an enforcement action in Thailand can deliver both criminal accountability and financial recovery within a single proceeding. Specifically, it highlights four important considerations for businesses forming IP enforcement strategies in Thailand:

  • Investigation quality. As part of an integrated enforcement strategy, a well-documented investigation that traces supply chains and preserves evidence strengthens both criminal prosecution and any subsequent damages claim.
  • Substantiation of reputational harm. Courts are increasingly receptive to structured explanations of brand value, distribution networks, quality control systems, and consumer trust.
  • Claiming damages within Thai criminal proceedings. Invoking Section 44/1 offers efficiency and leverage by avoiding the time and expense of separate civil litigation and aligning with public prosecution.
  • Emphasizing consumer safety. Sectors involving consumer safety receive particular judicial attention. Brand owners operating in food, cosmetics, pharmaceuticals, personal care, and other daily-use product markets may benefit from stronger damage assessment where consumer risk is demonstrable.

International brand owners evaluating enforcement options in Thailand should note the Thai judiciary’s deepening engagement with the economic harm and implications of IP infringement. While the country’s specialized IP Court has long been a strong point, this further evolution shows that Thai courts are not merely focusing on punishing infringers but are increasingly recognizing the commercial consequences borne by brand owners.

As a result of this shift, raid actions in Thailand should no longer be viewed solely as deterrent measures. They are becoming financially rational enforcement tools capable of generating tangible recovery.

In practical terms, the return on investment in well-prepared raid actions has steadily improved. With careful evidence gathering, strategic formulation of damages, and effective use of procedural tools, rights holders can now achieve both criminal accountability and meaningful financial redress within a single proceeding. This is an important step toward more commercially aligned and brand-conscious IP enforcement in Thailand.

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

Thailand’s cabinet has approved the draft Act on Liability for Defective Goods, commonly called Thailand’s “Lemon Law.” The Draft Act is currently pending consideration by Parliament. The draft law aims to strengthen buyers’ position in pursuing cases against sellers. While the Civil and Commercial Code offers provisions governing liability for defective goods, it is difficult in practice for buyers to successfully make a claim against sellers, particularly where defects are latent and not discoverable at the time of sale or delivery. By introducing product-specific rules and clearer remedies, the new law is intended to modernize Thailand’s consumer protection framework and align it more closely with international standards, and to help relieve the buyer’s burden of proof against the seller in product liability cases. If enacted, the draft act will take effect 180 days after publication in the Government Gazette, giving businesses a transition period to assess their compliance obligations. This article provides an overview of the key provisions of the draft act and highlights some practical considerations for businesses operating in Thailand. Scope and Key Definitions The draft act applies to sellers—defined as persons who sell goods in the ordinary course of business—and protects buyers, a term defined broadly to include not just the original purchaser but also transferees and successors in title. This expands the class of people who can bring claims. The law does not apply to used goods, live animals, or goods exempted by future ministerial regulation. It also leaves intact any separate warranties, promises, advertisements, or other guarantees a seller has given; those remain enforceable alongside the new statutory rights. General Liability for Defective Goods Sellers are liable for defects that exist at the time of delivery, regardless of whether the seller knew about them. Liability arises where a defect reduces: The benefit intended under

Patent enablement requirements are provided under Article 102 of Vietnam’s Law on Intellectual Property (IP Law). In particular, a patent specification must “fully and clearly disclose the nature of the invention to such an extent that, based on the specification, a person having ordinary skill in the relevant art can implement the invention.” In pharmaceutical and biotechnology patents, this requirement is more complicated and subject to more rigorous assessment. The Patent Examination Guidelines (Guidelines) of the Intellectual Property Office of Vietnam (IP Office) were amended in March 2026 to introduce Annexes III and IV for the pharmaceutical and biotechnology sectors, in which Annex III provides detailed guidelines on the assessment of specification requirements. These amendments were made under a project for strengthening capacity in industrial property examination between the Japan International Cooperation Agency (JICA) and the IP Office. Annex III provides detailed instructions on how examiners assess enablement in a pharmaceutical or biotechnology application, and offers examples of acceptable and unacceptable descriptions with regard to the enablement aspect. Enablement Requirements in Pharma and Biotech Patents Article 12.7 of Circular 10/2026/TT-BKHCN (Circular 10) adds to the requirements of Article 102 of the IP Law that the description must demonstrate the novelty, inventive step, and industrial applicability of the technical solution. For pharmaceutical composition subject matters, Article 12.9 of Circular 10 sets out that the description must present the results of clinical trials and/or the pharmacological effects of the claimed pharmaceutical composition, and must include at least the following information: Substance/mixture used. Testing method (system) employed. Information on the test results. Correlation between the pharmacological effects obtained from the tests and the application of the pharmaceutical product in the prevention, diagnosis, and treatment of diseases. The Guidelines note that pharmacological study results should be presented in a quantified manner, and pharmacological
