For the third year in a row, in the 2015 edition of IAM Patent 1000 – The World’s Leading Patent Practitioners, Tilleke & Gibbins has been ranked as a “Gold Band” firm in Thailand for its outstanding patent work over the past year. Only firms that deliver the highest quality of patent services are ranked in this band.

The editorial accompanying the ranking also had much praise for our firm. “The all-star patent team at legendary full-service firm Tilleke & Gibbins includes ‘veteran’ legal and technical experts whose ‘prompt and thorough service’ is the talk of the town,” the editorial said. Commenting on our litigation team, it continued: “its litigators steamroller the opposition in court and devise ‘astute and skillful’ enforcement strategies.”

In addition, the following four Tilleke & Gibbins lawyers were recognized as “Recommended Individuals” for their exceptional capabilities:

  • Alan Adcock. “Fluent Mandarin speaker Alan Adcock is a ‘superbly knowledgeable player in transactional work’ who ‘navigates foreign lawyers through the Thai legal system with approachability and ease.’”
  • Darani Vachanavuttivong. “Registration and licensing briefs are overseen by prosecution ‘superstar’ Darani Vachanavuttivong, who is a trusted guide for companies seeking to expand their rights throughout Southeast Asia.”
  • Nandana Indananda. “‘Top-tier’ Nandana Indananda makes the most of his ‘unparalleled experience’ as a former IP judge to craft persuasive arguments that really make an impression on the bench.”
  • Srila Thongklang. “Often representing pharmaceutical originators, Srila Thongklang has a sterling track record of victories garnered through his ‘impeccable communication skills and technical savvy.’”

These rankings are based on feedback obtained from telephone interviews with attorneys-at-law, patent attorneys, and in-house counsel. 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.
