Tilleke & Gibbins Lawyers Recognized as IAM Global Leaders in Patents

Four Tilleke & Gibbins lawyers have been named in this year’s Global Leaders list from Intellectual Asset Management (IAM). The list recognizes the world’s most outstanding private practice experts in patent law. Alan Adcock, Darani Vachanavuttivong, and Nandana Indananda have been included in the list for Thailand—three of the four individuals listed for Thailand—while Thomas Treutler is recognized for Vietnam.

To qualify for this prestigious honor, individuals must rank in the gold tier of the IAM Patent 1000, a highly respected annual directory that identifies the top law and attorney firms and individuals in the world’s most significant patent jurisdictions. The selection process involves a comprehensive four-month research process carried out by a full-time research team that gathers hundreds of written submissions from firms, conducts face-to-face and telephone interviews, and corresponds with patent lawyers, attorneys, and their clients.

Candidates for IAM Global Leaders are selected based on their expertise, experience, and ability to innovate, inspire, and deliver value for their clients. Inclusion on the list is a strong endorsement of the exceptional skills and dedication these lawyers have shown for their client in the field of patents.

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.
