Tilleke & Gibbins is proud to announce that four litigation cases handled by the firm have been selected among the nine Distinguished Judgment Awards granted by Thailand’s Central Intellectual Property and International Trade Court (IP&IT Court) for the period from October 1, 2024, to August 31, 2025. This recognition highlights the complexity, novelty, and legal significance of these cases, which were chosen based on stringent criteria including new legal issues, high evidentiary volume, and intricate legal arguments. Among these four cases, one was singled out as the “Most Distinguished Judgment” – the landmark trademark squatting case involving the trademark rights of our client, Thailand’s largest state-owned energy conglomerate, and its subsidiary. In this case, the defendants had filed 52 trademark applications mimicking our client’s marks, making it the largest trademark squatting dispute in Thai history. On April 30, 2025, the IP&IT Court ordered the cancellation of multiple infringing trademarks, setting a benchmark for IP enforcement against trademark squatters in Thailand. The other three recognized cases demonstrate Tilleke & Gibbins’ breadth of expertise in IP litigation: Patent infringement and invalidation involving trade secrets misappropriation. Trade dress infringement of a unique packaging. Landmark Luckin Coffee case involving trademark infringement and invalidation. The IP&IT Court handles approximately 200 IP civil litigation cases each year, and our IP litigation team has typically been involved in 25–30% of them, reflecting our dominant role in shaping IP jurisprudence in Thailand.

Thailand currently lacks a specific franchise act. Consequently, the legality of any franchise agreement is determined by its compliance with various existing laws, such as the Civil and Commercial Code, the Trademark Act B.E. 2534 (1991) (as amended), and the Unfair Contract Terms Act B.E. 2530 (1997). Thailand is a freedom-to-contract jurisdiction. This allows for a high degree of flexibility and autonomy in contractual arrangements, provided that the terms do not violate any laws or public policy and do not fall under the scope of unfair contract terms. Given this, the requirement for fairness in franchise agreement terms often leads to uncertainty, but decisions from the Trade Competition Commission of Thailand (TCCT) can provide guidance on whether specific contentious terms are in fact fair.  One issue worth examining in this light is the inclusion of terms on nonrefundable franchise fees and strict purchasing conditions. Franchise Fee: Unfair to Refuse Refund? Nonrefundable franchise fees represent a significant upfront investment for franchisees, often becoming a point of contention if the franchise relationship deteriorates or the franchisor ceases operations. Their fairness and enforceability are frequently scrutinized by regulatory bodies like the TCCT, highlighting the critical balance between contractual freedom and franchisee protection. Faced with one such case, the TCCT considered whether it was unfair for the franchisor to refuse to refund the franchise fee after the franchisor ceased operations.  The franchisee had entered into a service agreement on August 2, 2021, and begun operating on October 9, 2021. However, by November 21, 2023, the franchisee was notified that the system would be shut down for maintenance, and by December 26, 2023, the franchisor announced the cessation of operations due to financial losses. The franchisee then requested a refund of the franchise fee. Unfortunately for the franchisee, the TCCT found that the franchisor’s
