Y.P. Lee, Mock & Partners has often been mentioned as the largest IP law firm in Korea, but this is only one way of describing our firm.

Our IP attorneys with the experience in the relevant technology offer expertise to do everything it takes to the full satisfaction of our domestic and overseas clients.

Our foreign clients often comment that “applications prepared by your firm have been better than any others from Korea” and “we highly recommend your service to our clients.”


Y.P. Lee, Mock & Partners is dedicated to fully understand the needs and concerns of our foreign clients which include a number of Fortune 500 companies. Providing a high quality prosecution service in order to obtain a strong and effective protection for our foreign clients requires far more than overcoming the language barriers.

The motto “Be Proactive!” has been one of our guiding principles that we strongly adhere to in serving our clients. In addition to following the specific instructions from our clients, we proactively note issues which may require more attention as we are always prepared to strategically provide our service according to the changing requirements of our clients in order to maximize the protection for our clients. Because we strive to be proactive, we can offset some of the difficulties which may arise from communication and cultural differences caused by geographical remoteness.
