Yoon & Lee International Patent & Law Firm
Yoon & Lee International Patent & Law Firm provides a comprehensive range of services for IP rights, including patents and trademarks, as well as consultation services for the management and enforcement of IP rights. The firm was founded in 1989 and became a limited liability company in 2017. Yoon & Lee offers optimised IP services for the benefit of its clients through close cooperation and teamwork that maximise the high levels of expertise and experience of its staff of 89, which includes more than 35 foreign and domestic patent attorneys and lawyers. The firm is particularly well known for its patent technical expertise and long-term relationships with its clients in that practice area.
The firm’s main specialisation is in patent prosecution, especially in the electronics and software, chemistry and biotech, and mechanical and mechatronics sectors. One of the firm’s major strengths in the patent sector is its technical knowledge and expertise; it employs a high percentage of patent attorneys and technical specialists in comparison with general law firms and other patent law firms in Korea (33 patent attorneys and 23 patent engineers). In particular, the firm offers an efficient and effective combination of patent attorneys (including a partner patent attorney with an LLM from the United States) with extensive experience, including substantial experience appearing before district courts and high courts, as well as the patent court. The firm also has technical advisers with advanced degrees (PhDs and other postgraduate qualifications) in their specialist subjects, including electrical engineering, electronics, communications, computer science, mechanical engineering, chemistry, biotechnology, pharmaceuticals, cosmetics and life sciences. Based on their strong technical knowledge, the firm’s specialists are often called to testify as expert witnesses in court cases.

The team delivers a wide range of trademark and design services and acts for businesses, both Korean and from overseas, in all market sectors.
Yoon & Lee’s clients span the globe and most industry sectors; they range from major international companies with established global operations to small and medium-sized enterprises.
