Strong Regional Performance for Tilleke & Gibbins in Managing IP Patent Survey

Managing IP magazine, which has been rolling out its highly regarded IP Stars rankings in stages this year, recently released the results of its patent survey, and Tilleke & Gibbins earned high rankings across key Southeast Asian jurisdictions:

  • Thailand – Tier 1 for the 20th consecutive year
  • Vietnam – Tier 1 for the 8th consecutive year
  • Indonesia – Tier 2 for the 3rd consecutive year

The rankings show not only the firm’s excellence in patent work across the region but also its consistency—two decades in Tier 1 for Thailand, with the firm’s Vietnam practice getting close to a decade of its own. Even the relatively new Indonesia operations have been recognized in each of the past three years, and in this latest edition only two firms in Indonesia are ranked above Tilleke & Gibbins. Managing IP does not yet provide patent rankings for Tilleke & Gibbins’ other jurisdictions, Cambodia, Laos, and Myanmar.

The trademark survey is a part of IP STARS, MIP’s specialist guide to the world’s leading intellectual property firms and practitioners. For more information and to browse the full copyright rankings, please see the IP STARS website.
