Supreme Court Finds “Bull” Marks Not to Be Confusingly Similar

World Trademark Review

The Trademark Act (BE 2534 (AD 1991)), as amended by the Trademark Act (No 2) (BE 2543 (AD 2000)), provides that, in order to be registered, a trademark or service mark must not be identical, or similar, to an earlier registered trademark. Additionally, a trademark must not be identical, or similar, to a well-known mark, and cause public confusion as to the proprietor of the mark.

In TC Pharmaceutical Industrial Co Ltd v Bullsone Co Ltd (13889-13891/2553, December 30 2010, released on October 10 2011), the Supreme Court has examined the possibility of confusion between a trademark application and an earlier registered mark that is well known in Thailand.

TC Pharmaceutical Industries Co Ltd filed an opposition with the Department of Intellectual Property against three applications filed by Bullsone Co Ltd for the registration of the trademark BULLSPOWER for goods in Classes 1, 2, and 4 of the Nice Classification. TC Pharmaceutical claimed that Bullsone’s trademark was confusingly similar to its well-known mark RED BULL and related ‘bulls’ device, which are registered for goods in Classes 29, 30, 31, and 32. The trademark registrar found that BULLSPOWER was not confusingly similar to the RED BULL mark or the ‘bulls’ device. TC Pharmaceutical appealed to the Board of Trademarks, which agreed with the trademark registrar’s decision.

TC Pharmaceutical then filed a complaint with the Central Intellectual Property and International Trade Court (IP&IT Court) against Bullsone (as the first defendant) and the Board of Trademarks (as the second defendant). The suit claimed that the board’s decision was unlawful because the first defendant’s trademark was confusingly similar to TC Pharmaceutical’s trademarks. In particular, TC Pharmaceutical noted that the first defendant’s trademark contained the essential element ‘bull’, which was identical to the essential element of TC Pharmaceutical’s mark, and that the first defendant had disclaimed the exclusive right to use the word ‘power’. Therefore, the word ‘power’ was not an essential part of the first defendant’s mark.

The IP&IT Court disagreed with TC Pharmaceutical’s arguments and decided that the mark BULLSPOWER was not similar to any of the plaintiff’s marks. The IP&IT Court thus dismissed the complaint.

The plaintiff subsequently appealed to the Supreme Court, which affirmed the IP&IT Court’s decision. According to the Supreme Court, in considering the similarities between the marks, it is necessary to consider the overall appearance of the marks, rather than focusing only on certain elements.

The Supreme Court agreed with TC Pharmaceutical’s premise that the first defendant had disclaimed the exclusive right to use the word ‘power’ and that both marks shared the common word ‘bull’. However, the court held that the marks belonging to TC Pharmaceutical were RED BULL (or RED BULL and ‘bulls’ device), and that the goods covered by the parties’ marks were different. Therefore, the Supreme Court found that the first defendant’s mark was not confusingly similar to TC Pharmaceutical’s marks and, therefore, would not cause confusion among consumers.

The Supreme Court clearly made its decision on the likelihood of confusion by focusing on the appearance of the marks, their pronunciation, and the goods covered by each mark. The court did not give special consideration to the earlier mark’s well-known status.

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
