Yoon & Lee > Firm Profile
Yoon & Lee was founded in 1989 by Mr. Dong-yol Yoon, one of the leading figures in the Korean IP sector and a former head of the Korean Patent Attorneys Association. The firm grew rapidly after gaining a strong reputation for patent filing, prosecution, and registration both in Korea and overseas, especially in the electronics, software, mechanical, pharmaceuticals, cosmetics, and biochemical sectors. Recently we have been strengthening our trademark and design sector led by Mr. Sang-yong Lee, a former trademark examiner at the Korea Intellectual Property Office (KIPO). In April 2017, the firm converted to a limited company with the senior partners becoming the owners of the company. The new structure provides a better structure for long-term growth by enabling clients to have greater trust and confidence in the firm’s stability.
Yoon & Lee has a wide range of clients in terms of geographical distribution and industrial sector and also ranging from established global operations to small and medium sized enterprises. The firm’s philosophy is to create strong trust-based relationships as reflected in the near 30-year long relationships developed with major Korean companies. We believe that honesty and a reputation for excellent work leads to satisfaction for its clients and a good reputation for the firm.
In particular, we are well-known for the high percentage of patent attorneys and technical specialists in comparison with general law firms and other patent law firms in Korea, which allows us to offer an efficient and effective combination of patent attorneys, former KIPO examiners, foreign attorneys, and technical advisors with advanced degrees.
