It is widely recognised in the market for its high-quality representation, particularly in trademark litigation matters.

Work highlights 

Representing US-based streetwear brand Supreme in ten cancellation actions before the Patent Court. The cancellation actions are against imitation marks which already received negative decisions at the IPT level and were appealed by the registrant.  

Acting for energy drink giant Red Bull in a dispute with domestic company named Bulls One, an automobile fluid manufacturer and distributor. The dispute involved mutual attacks on the parties’ trademark registrations, and was particularly complex and interesting because market survey evidence was being utilised, a relatively new area of law in Korea.  

Representing Microsoft in a case against Asiamuyeok Company for the cancellation of its domain name and an injunction against its sale of product keys for Windows 10 programme software without the client’s permission. This is the first case in Korea on product keys provided in the licensing of software and will have a significant impact on the widespread sale of product keys in the country. In February 2021, Microsoft received a favourable decision from the District Court and two weeks later, Asiamuyeok appealed the decision to the High Court. The case is now pending.
