Tsai, Lee & Chen is a top-tier IP law firm based in Taipei, Taiwan with more than 170 IP professionals and lawyers. Founded in 1995 by Thomas QT Tsai, who is also the founding president of Taiwan Patent Attorneys Association (TWPAA), the firm boomed with the advent of Taiwan’s high-tech industrialisation. The firm has since developed a full service IP law firm encompassing all areas of IP from prosecution to litigation, garnering tremendous trust from its reputable domestic and international clientele.

The firm manages more than 30,000 patents and 18,000 trademarks worldwide and has established a professional network of 1,300 with global IP law firms and associates. The firm’s leading lawyers and patent attorneys enjoy diverse technical and legal backgrounds. A growing number of patent attorneys possess dual qualifications in the jurisdictions of Taiwan, China and the US Patent and Trademark Office. Integrating the efforts of an elite team, Tsai Lee & Chen can provide cost-effective patent preparation with quality work products, and has demonstrated sophistication in both offensive and defensive IP strategies.

The firm’s domestic and foreign lawyers are familiar with cross-border legal practices, and licensed to practice in Taiwan, China and the New York State. They are creative thinkers who have established landmark IP cases before the court, and are proficient in laws relating to unfair competition and trade secret misappropriation.

The firm has successfully helped many Fortune 500 companies, as well as many small and medium-sized enterprises, to bridge the gap of IP protection between their home jurisdiction and the Greater China region.
