Tsai Lee & Chen is a prosecution firm with offices in Taipei, Taichung and Tainan. The firm is made up of five partners and approximately 70 IP professionals, including 56 patent agents. The team's strength lies in patent work, particularly filing and drafting. The firm also has contentious capabilities but tends to only handle issues for its prosecution clients. Notable clients include Qualcomm, Red Bull, Microsoft and Hitachi.
It has been another successful year for the firm as it consolidates its position in the top tier of the patent prosecution table. One client explained why she chose the firm: "It is very important to work with people who know cross border practices. And for me it was Europe. The team explained the differences in practices and cultures to better understand the needs of the European IP Office." Yiling Liu is a highlighted practitioner, described by clients to be effective and an efficient trade mark practitioner. Crystal Chen is another notable practitioner valued for her legal advice.
The firm has been advising Red Bull in extending its trade mark protection to include media exposure at international motorsport events. Liu and Iris Lin led this case and provided the IP Office with comprehensive evidence illustrating its client's strong involvement with motorsports, including Formula One racing. By highlighting the client's work in motorsports, the team extended the trade mark protection to an unrelated industry.
