Testimonials

‘Yulchon gives us a clear answer when we have to make a business decision. Other major firms in South Korea often be too conservative to shift their responsibilities to the company, but it doesn't help many times.’
‘Myunghoon Kim is an expert when dealing with many IP cases including trademark and copyright. He can arrange the priorities when the company needs some urgent advisories, so I did not have to contact with other lawyers other than him. Also, when I worked with him, I got a wide view of the specific issue. Even though the issue was only related to specific IP matters, he picked up other legal issues that I could not think about. It was very helpful for the company.’
‘Yulchon's intellectual property team have a deep understanding of both specialised technology and the complex legal and regulatory dynamics of emerging industries to provide clients. It consists of expert members encompassing both traditional and emerging technologies, so it demonstrates analytical power that matches industry trends. In particular, although the pharmaceutical industry is a field that is very sensitive to technological trends, we have never once received disappointing results from an IP analysis and research project.'
‘Yong Min Lee has significant experience in intellectual property transactions such as technology licensing and other intellectual property licensing and intellectual property due diligence. He has an admirable, service-minded attitude. He answers customer enquiries with sincerity and performs his work efficiently. He also passionately researches problems, reacts and communicates with us. And he quickly recognises what our wants and needs, and is the one who sacrifices his time for our case.’
‘I received assistance from various technical professionals along with legal advice, which was incredibly helpful. Their ability to provide comprehensive support that covered both legal and technical aspects made a significant difference.’
‘I sought assistance from other firms with the same inquiries and received responses. However, the level of detail and understanding I received from this practice was unparalleled. They were able to identify and address cases I wasn't familiar with and effectively communicated my needs. This exceptional service sets them apart from the rest. Their expertise, proactive approach, and dedication to client satisfaction truly made a significant difference. I highly recommend this practice to anyone looking for superior legal support.’
‘In Yulchon's IP team, there are patent attorneys. Attorneys and patent attorneys work in collaboration with each other for one project. This system enables the provision of specialised opinions to clients based on a better understanding of the technology.’
‘Kyung Ae Yoon is a patent attorney practising in the pharmaceutical field. Ms. Yoon has had a long career and is involved in a lot of activities, so she has a lot of background in the pharmaceutical industry.’
