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.

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

Every month, VAT-registered businesses in Thailand calculate their output and input VAT and file a return to pay the net amount due or claim a refund. Yet a common and costly dispute arises when a business that has paid input VAT to its supplier—and done everything asked of it—later finds that input VAT rejected on the grounds that the tax invoice was issued by “a person not entitled to issue tax invoices.” In these cases, a buyer may have confirmed the supplier’s VAT registration on the Revenue Department’s website, paid through the banking system, received a complete tax invoice, and kept full payment and inventory records. Even so, if the Revenue Department later determines that the supplier did not genuinely make the sale or collected the VAT without remitting it, the department can disallow the input VAT and assess additional tax, surcharge, and penalty—often more than a year after the transaction. A new article from tax and dispute resolution specialists at Tilleke & Gibbins in Bangkok examines how the Revenue Department and the courts approach these disputes, including two recent Supreme Court (Tax Division) decisions confirming that the taxpayer bears the burden of proving a supplier genuinely sold and delivered the goods and received payment. It considers why the VAT registration system offers no legal safe harbor, why the evidentiary burden falls hardest on online and cross-border transactions where buyers and sellers never meet, and how the Revenue Department’s own digital infrastructure could detect non-remitting suppliers at the source rather than shifting the loss to good-faith buyers. The article also sets out practical guidance: how to build a comprehensive “know-your-supplier” file at the time of a transaction, the procedural steps and strict deadlines for challenging a VAT assessment, and why dispute readiness belongs alongside tax planning at the center

Intellectual property (IP) protection sometimes hinges on fame and recognition. However, this alone will not always be sufficient to overcome an IP dispute when it involves contractual obligations or registered rights. Below are five cases from around the world that tackle some of the basic issues in IP registration, ownership, commercialization, and enforcement. 1. USA: Taylor Swift Trademark Application Refused Taylor Swift recently filed a trademark application to register “The Life of a Showgirl,” which is the title of her 12th studio album. When examining a trademark application, the examiner considers various factors before deciding whether it should be registered. One of these factors is whether there is a likelihood of confusion (i.e., would a regular consumer mistake the origin of the trademark). In Taylor Swift’s case, the US Patent and Trademark Office (USPTO) decided that that there would be a risk of confusion. This decision was based on the existing registered trademark, “Confessions of a Showgirl,” owned by Maren Wade, which was registered in 2015. The USPTO refused Taylor Swift’s application based on the shared key distinctive element “of a showgirl,” the lack of sufficient distinguishing terms, the marks being used in overlapping markets (entertainment and performances), and because consumers may assume a common commercial source. Maren Wade then filed a lawsuit in California against Taylor Swift and her affiliated companies, arguing that Taylor Swfit’s branding is confusingly similar in structure, wording, and overall commercial impression to her registered mark. She is also drawing on the USPTO’s refusal of Taylor Swift’s application to support her argument of a likelihood of confusion. A judgment has not yet been reached in this case, but it serves as an important reminder of the importance of satisfying the essential elements required for IP registration. 2. Australia: Katy Perry v. Katie Perry In

Vietnam’s new E-Commerce Law, which took effect on 1 July 2026 along with its implementing Decree No. 248/2026/ND-CP (Decree 248), marks a significant development in the country’s approach to online intellectual property (IP) enforcement, reflecting a clear shift from a reactive model of intermediary liability to one that expects platforms to play a more active role in preventing infringement. From notice-and-takedown to platform responsibility The most significant change introduced by the E-Commerce Law is the transformation of the legal role of e-commerce platforms. The existing safe harbor provisions under the IP Law and the copyright notice-and-takedown regime established by Decree 17/2023/ND-CP (Decree 17) largely required intermediaries to act only after receiving notice of infringement. Once infringing content had been removed, the platform’s legal obligation was generally considered fulfilled. The new legislation adopts a fundamentally different approach. Article 17 of the E-Commerce Law requires intermediary platforms to screen information relating to goods and services before publication in order to prevent listings involving counterfeit or IP-infringing goods, and goods of unknown origin. Rather than relying exclusively on complaints from rights holders, platforms are now expected to implement preventive measures before infringing listings become publicly available. Decree 248 further requires platforms to update keyword filters based on recommendations issued by competent authorities. These filtering mechanisms are intended to prevent prohibited listings from appearing on the platform and represent a further move away from a purely complaint-driven enforcement model. The legislation also introduces Vietnam’s first statutory stay-down obligation. Under the E-Commerce Law and Decree 248, major digital platforms must maintain automated systems capable of reviewing, warning against, and removing unlawful listings while also implementing measures to prevent repeat violations, defined under Decree 248 as conduct that has previously been identified and handled by the platform, but continues to recur. This obligation addresses one
