Patents and utility models are a core competency of Yulchon’s IP Group.  With a team comprised of former judges, KIPO patent examiners and directors, government litigation attorneys, in-house counsel, engineers, and researchers, the IP Group has the expertise and experience to understand the client’s business goals and provide tailored advice relating to patent and utility issues in any technology.  The former judges served on the Patent Court, on various district courts including the Seoul Central District Court, in the IP division of the Seoul High Court (court of second instance), and as research judges at the Supreme Court (court of third and final instance).  The attorneys and patent attorneys of the IP Group have degrees in electronic engineering, mechanical engineering, chemical engineering, computer science, pharmacy, civil, urban and geo-systems engineering, and naval architecture and ocean engineering.

The IP Group has successfully represented numerous domestic and overseas companies in regard to all aspects of patent and utility model disputes in the Korean courts, the Korean Intellectual Property Tribunal, and the Korean Trade Commission.  Experience in the Korean courts include infringement litigations, litigations for cancellation of trial decision, patent transfer litigations, and employee invention compensation litigations.  Experience in the Korean Intellectual Property Tribunal include actions relating to invalidation, confirmation of scope of right, and correction.   Experience in the Korea Trade Commission include investigations of injury to domestic industry by unfair international trade practices resulting from violations of IP rights.  The IP Group has also advised on diverse IP related matters, such as conducting pre-litigation reviews on likelihood of patent infringement and invalidity, taking countermeasures against infringers, formulating effective defenses against allegations of patent infringement, assisting with negotiations, conducting IP due diligence for acquisition or sale, reviewing and drafting license agreements, and advising on employee invention rules and compensation.  The IP Group also includes an International Dispute Management Team comprised of foreign licensed attorneys with extensive experience in overseas patent litigation.  As a result, Yulchon’s IP Group can efficiently handle Korean patent/utility model disputes and collaborate with the attorneys in foreign countries for one or more concurrently pending foreign litigations.
