Managing IP: Thang Duc Nguyen and Linh Thi Mai Nguyen Quoted on Vietnam’s IP Procedures

Managing Intellectual Property

On January 15, 2018, Vietnam implemented changes to its patent and trademark examination procedures to bring them more in line with international standards. In a recently published article on the revamped procedures, Managing Intellectual Property quoted two lawyers from Tilleke & Gibbins’ Hanoi office.

Commenting on the fact that new details can no longer be introduced at the appeal stage, Thang Duc Nguyen, head of patent, explained that the change was aimed at reducing the number of appeals. “When applicants supplement new facts or arguments at the appeal stage, it led to a huge appeal workload and numerous unsettled and long-pending requests.”

Regarding the extended deadlines for responding to office actions, Linh Thi Mai Nguyen, head of trademark, shared, “The periods in the old circular were quite short compared to other countries, which caused difficulty for applicants, especially overseas ones, to meet the deadlines. IP practitioners find the extended periods more reasonable and provide a more practical timeline for response.”

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.
