Y.P. Lee, Mock & Partners has been often referred to as the largest IP law firm in Korea, but this is only one of the many ways to describe our firm. We have always strived to provide quality services to our clients.

Comments from our foreign clients such as “The applications prepared by your firm are better than any other ones from Korea” and “We have no reservation in recommending your services to our clients” are among the most honorable accolades we have received.

Highly experienced trademark attorneys also provide quality services for trademark cases.

In addition to our strong prosecution practice, for which we have been ranked as a top tier firm in Korea by several IP survey institutions, we are also active in technology and IP rights analysis, performing due diligence, IP consulting, licensing, IP portfolio management and more.
