The firm

The history of Lee and Li can be traced back to the 1940s. Mr. James Lee, one of the two founders, began his practice with two U.S. attorneys during that period in Shanghai. The other founding partner, Dr. C. N. Li, also practiced in Shanghai at that time. Both of them specialized in transnational legal matters.

Mr. James Lee established his own firm in Taipei in 1953 and was later joined by Dr. C. N. Li in 1965, henceforth laying the foundations of Lee and Li. Mr. James Lee passed away in 1970. Subsequently, with an eye toward sustainable operations, Dr. C. N. Li renamed the firm Lee and Li. The firm had around 30 employees at that time and focused mostly on transnational legal matters and intellectual property right issues.

In 2015, Lee and Li enters its 50th year as the largest law firm in Taiwan owing to the solid foundation laid at the beginning. The firm is known for expertise in all legal fields and offers a full range of services. We have been steadfast in our commitment to the quality of services to clients and the country. To sustain its tradition of excellence and build on the competitive edge for which the firm is renowned, in 2004, an initiative was made to streamline the firm’s organization and management. On January 1, 2005, Dr. C. V. Chen was elected the Chairman and Chief Executive Officer, and Kwan-Tao Li was elected the Chief Senior Counselor. In 2008, Dr. C. V. Chen continued to serve as the Chairman and Nigel N. T. Li was elected the Chief Executive Officer. Kwan-Tao Li retired on January 1, 2009 and was appointed the Chief Of Counsel. The number of Lee and Li’s staff has increased since then. With expertise covering all professional areas and building on the foundations laid down over decades, the firm has been steadfast in its commitment to provide quality services to clients and the country.

Areas of practice

Lee and Li is a full-service law firm and understands the need to diversify and specialize. In response to the rapid developments in trade and technology and to satisfy the needs of our clients, we are constantly refining and expanding our practice areas. Over the decades, we have built one of the largest intellectual property right practices in Taiwan, and have been involved in the phenomenal growth of foreign direct investment since 1970s. We were a pioneer in developing banking and capital market practice in the 1980s, and played a pivotal role in the formation of technology law practice in the 1990s. We are also active in public construction, government procurement and merger and acquisition. We stay relevant by staying current on the latest developments in every industry and apply our legal skills to help clients achieve their business goals.

Constant improvement, teamwork and specialization enable us to provide quality services. We restructured our resources and formed practice groups, which span the five departments of the firm, i.e., banking and capital markets, corporate and investment, trademark and copyright, patent and technology and litigation and ADR. Our professionals are placed in the groups in accordance with their expertise and interests (please log onto our website for further details). We believe that the practice groups match the clients with the appropriate specialists and ensure both efficiency and specialization.

In addition to the vertical integration achieved through practice groups, we also formed cross-department, cross-specialty special task forces (“STF”) dealing with mainland Chinese and Japanese markets and dispute prevention and settlement (i.e., P.R.C. Practice STF, Japan Practice STF and Dispute Resolution STF). We integrated resources horizontally to further enhance the quality of our service.

Our services are performed by over 100 lawyers admitted in Taiwan, patent agents, patent attorneys, trademark attorneys, more than 100 technology experts, and specialists in other fields. In order to provide services related to law or intellectual property right issues, most of our professionals have degrees in law, technology and/or business management in Taiwan or from abroad. Many of our colleagues are licensed to practice law in the United States, and some have also passed the bar exam in the People’s Republic of China or are licensed patent attorneys in the United States and the People’s Republic of China.
