It is an international patent law firm, representing its clients in all cases of intellectual property rights, such as patent, utility model, design, trademark, copyright, computer program, semiconductor layout-design, licensing, technology transfer, infringement, trial and litigation.

In order to maintain a close and cooperative relationship with the Korean Industrial Property Office (KIPO) and for flexible execution of cases, Wonjon's main office is situated in the same building as
