IAM Patent 1000: Tilleke & Gibbins Setting the “Gold” Standard in Patent Services

Intellectual Asset Management

The IAM Patent 1000 – The World’s Leading Patent Practitioners 2013 has ranked Tilleke & Gibbins as a “Gold Band” firm for our top-quality patent services in Thailand. The IAM Patent 1000 describes “Gold” ranked firms as “the crème de la crème; their success hinging on reputations established over lengthy periods of time–something which enables them to secure the most high-profile big-ticket work from the most demanding of clients.”

After an extensive research process conducted over several months by a team of full-time analysts who consulted our peers and clients, the publication praised Tilleke & Gibbins as being a “top-quality outfit,” with one of its sources tipping us to be “the firm to beat.” Darani Vachanavuttivong, co-managing partner and managing director of the intellectual property department, was hailed as a “virtually peerless” figure in the community. Alan Adcock, partner and deputy director of the intellectual property and regulatory affairs groups, was commended for his commercialization and licensing acumen. The publication identified both Darani and Alan as practitioners companies turn to when only the best patent work will do.

Presented by Intellectual Asset Management (IAM) magazine, the IAM Patent 1000 is a standalone publication that identifies individual and firm expertise in all major areas of patent law and practice around the globe. Close to 1,500 interviews with patent specialists were conducted across the globe. Legal and attorney firms and individual practitioners qualify for inclusion in the IAM Patent 1000 upon receiving sufficient positive feedback from market sources.
