Reasons Why Korean Companies Rarely File International Patent Applications?
The Madrid System refers to the system of the international registration of marks and its biggest advantage lies in reduced costs. As such, Korea also became a member country of the Madrid Union in 2003, but there are not many cases of Korean companies using the system. The problem is that any change in a trademark of the original country also affects that registered in each country. The phenomenon is called a “concentrating attack,” and local companies regard the unified structure as a burden.
Therefore, they prefer trademark filing separately in specific countries.
