We cover both inbound and outbound IP filings - prosecuting patent, trademark, utility model and design applications in Korea, while also supporting the procurement of IP rights abroad. As one example, for Korean clients seeking US patents, our experienced attorneys work closely with trusted US firms to ensure high quality services, from preparing the English specification to patent grant. For US clients filing in Asia, we can act as the hub using our close network of trusted Asian law firms. Our services have been recognized by many clients as providing a seamless solution to the challenges presented by distance, language and culture.


We are the leading practice in Korea for all manner of IP-related disputes, including civil and criminal proceedings, mediations, arbitrations, invalidation and scope confirmation actions at KIPO, Korea Trade Commission cases, and Korea Fair Trade Commission cases. Our Group also assists clients with US IP litigation, working with our network of trusted local firms to provide tailored legal services. Some of the work we have done in such cases include settlement negotiations, litigation discovery and strategy counseling. 


We provide comprehensive IP consulting services, including the negotiation of licenses, strategic alliances, assignments and joint development projects. Our work in this area has also involved providing IP infringement and validity opinions, along with counseling on strategic IP procurement, management and enforcement.


Our IP investigation services include prior art searches, freedom-to-operate investigations, and ownership/assignment investigations. Our team members have the capability of simultaneously conducting prior art searches in various languages, including Korean, Japanese, English and Chinese. This maximizes the efficiency of our work, assisting clients to accurately evaluate the IP landscape in the US or Korea.
