ABOUT US

아이콘

We are specialized in the pharmaceutical, biotechnological and chemical field.

Our firm has focused on pharma/bio/chemical IP cases ever since its establishment in February 2006. As inventions of this field encompass complicated technical concepts and various cutting-edge technologies, only specialists in this field could understand such complex inventions and represent the same before the Korean Intellectual Property Office (KIPO) and the Patent Court.

아이콘

We are proud of the best success rate in patent trials and litigations in Korea.

Patent trials and litigations are the highest arena of expertise where extensive technical and legal knowledge and accumulated litigation experience are essential.

아이콘

We provide professional consulting in every stage of IP management.

Our firm provides patent strategy for every stage of IP management, from the R&D planning stage to the patent acquisition and enforcement stage. Some examples of such strategies include technology trend analysis through patent mapping, design around, patent portfolio establishment, pre-review of patent infringement, and monitoring of patents covering competitor’s product.
