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

World Trademark Review

This article first appeared on WTR Daily, part of World Trademark Review, in December 2011. For further information, please visit www.worldtrademarkreview.com.

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.

Modern agricultural machinery is no longer purely mechanical but instead technology dependent. Modern tractors, harvesters, and other farm equipment increasingly incorporate embedded software, electronic control units, sensors, and digital diagnostic systems. While such technologies enhance efficiency, productivity, and precision farming, they also affect the manner of equipment repair and maintenance. As a result, farmers and independent repair providers may have little practical choice but to rely on authorized dealers, even for routine maintenance and repairs. Section 36 of Thailand’s Patent Act reflects the principle that the authorized sale of a patented invention usually exhausts the exclusive right of the patent owner over the specific product. This means that upon legal sale of the patented product, it can typically be used or resold without further authorization from the patent holder. This principle is relatively straightforward when applied to traditional mechanical equipment. Ownership of a machine ordinarily carries with it the practical ability to diagnose faults, replace worn parts, and restore the equipment to working order. Modern agricultural machinery, however, increasingly depends on embedded software, proprietary diagnostic systems, firmware updates, and other digital resources that may remain under the control of the manufacturer or patent holder. This tension lies within the “right to repair” debate. In the United States, on July 8, 2026, the Federal Trade Commission and five states announced a settlement with Deere & Company resolving allegations that Deere had unlawfully restricted farmers’ and independent repair providers’ ability to repair their equipment. Under the terms of the settlement, for the next ten years, Deere must provide repair resources, including software capabilities, on terms equivalent to those provided to authorized dealers. The Deere settlement highlights that the nature of ownership is changing, but legal concepts have not kept pace. Traditional patent-law concepts, including patent exhaustion, were developed with physical products

Cambodia’s Ministry of Justice has launched a new platform on its official website to publish notices of forced sales issued by each municipal and provincial court of first instance. The platform’s stated purpose is to inform the public and facilitate greater participation in forced-sale auctions conducted in connection with court-ordered enforcement proceedings. How the Platform Works The platform publishes forced-sale notices from courts of first instance across Cambodia’s municipalities and provinces and includes a link where the public can view properties currently subject to forced sale. To participate in a forced-sale auction, individuals can download Khmer-language bidding application forms through links provided on the platform. The form typically requires the applicant’s name, sex, year of birth, identity card number and issue date, and address, together with details identifying the immovable property (including its ownership certificate number), the relevant enforcement case number and date, and the reference to the public auction or tender announcement issued by the court. Completed application forms must be submitted directly to the specific municipal or provincial court that issued the forced sale. For further inquiries about a particular forced sale, interested parties should likewise contact the relevant municipal or provincial court. Forced Sale of Immovable Property in Cambodia The publication of these notices relates to the forced sale procedure for immovable property under Cambodia’s Code of Civil Procedure (CPC). Unlike property seizure by a court, a forced sale is a compulsory execution proceeding—a subsequent enforcement step that arises only after an underlying dispute has been adjudicated and a debtor fails to pay the debt or outstanding amount due under a final and binding judgment or other enforceable title of execution. For the purposes of this procedure, the term “immovable property” under the CPC refers to land, registered buildings, jointly held shares of such property, registered

Thailand has finalized its social media KYC (“know your customer”) rules under Notification of the Electronic Transactions Commission on Measures to Prevent Technological Crimes for Social Media Service Providers (No. 2), which was published in the Government Gazette on May 5, 2026, and will take effect on November 1, 2026. While an early draft of the notification proposed requiring social media platforms to arrange identification of every user account, the final notification is significantly more targeted, focusing on paid online advertising and advertiser identity verification. Though the regulatory initiative primarily aims to combat online fraud and technology-related crimes, it also has important consequences for intellectual property enforcement, because the verified platform records that will be generated under the new requirements can help IP rights holders to identify anonymous online infringers. Key Regulatory Mandates The notification requires social media service providers to verify the identity of advertisers before their paid advertisements are published and disseminated in Thailand through social media, regardless of whether the advertising fees come from the advertisers or third parties. Verification of an advertiser is valid for one year, after which verification would have to be performed again before the platform could publish additional paid advertisements from the advertiser. Permitted verification methods are specified under the notification. A platform may verify an advertiser by checking identity evidence and confirming the connection between the advertiser and that identity evidence, with the notification giving facial comparison against certain government-issued identity documents as an example. Alternatively, platforms may verify advertisers through a digital identity verification and authentication system with an identity-proofing assurance level not lower than the level prescribed by Thailand’s Electronic Transactions Commission. The notification further requires platforms to retain only the advertiser’s information necessary to identify the advertiser, beginning from the start of the advertising activity and for

Introduction: A Trademark Paradox in Sustainable Packaging Walk into any Thai supermarket, and the label-free water bottle is no longer a novelty. Thailand’s packaging market, valued at approximately USD 15.68 billion in 2025, is shifting toward minimalist, plastic-light designs as ESG pressures reshape how brands present their products. The country generated roughly 5.68 million tons of plastic waste in 2021, with a recycling rate of only 19 percent, and regulators are now considering rules that would allow label-free bottled water relying on embossing, laser printing, or QR codes instead of wrap-around labels. As packaging itself becomes the brand identifier, a paradox emerges: designs built to say the least often struggle hardest for protection under Thai intellectual property law. The Trademark Barrier: When Shape Is Not Enough Section 7, paragraph 2(10) of the Thai Trademark Act deems a shape distinctive only if it is not the natural form of the goods, is not necessary to achieve a technical result, and does not add value to the goods. The Department of Intellectual Property’s 2022 examination guidelines apply this test conservatively, as the following examples illustrate. A plain water bottle relying on subtle contours to signal its brand is typically read as just another bottle, not a source identifier. Acquired distinctiveness offers a theoretical escape route, but it demands extensive evidence of sales, advertising, and consumer recognition—an especially heavy burden for new entrants whose minimalist packaging has not yet achieved market prominence. The result is a structural bias against precisely the design innovation that sustainability goals are meant to encourage. Design Patents: A Partial, Imperfect Substitute Design patent protection, covering a product’s shape, configuration, or ornamentation, appears to offer an alternative route. In practice, it is constrained by the same forces driving the minimalist trend. Because many brands converge on similar solutions—clear
