VI. Enhanced Protection of Patentee
Criminal Penalty
In Korea, patent infringing activity is punishable as a crime and the criminal penalty is provided to be up to five (5) years imprisonment and the criminal fine is up to 50 million Korean won (about 40 thousands USD). The new law enhanced the criminal penalty against patent infringement up to seven (7) years and 100 million Korean won (about 80 thousands USD). In case of patent infringing activities by a jurisdic person, the fine is increased up to 300 million Korean won (about 240 thousands USD).(Art. 225, Art 230)

2. Amount of Damages
In a damages suit based on patent infringement, the patentee has been required to show the amount of damage caused by the infringing activities of the defendant, which is not easy at all. To ameliorate the difficulties of showing the amount of damage, the current Patent Act has a provision to assume the patent owner's damages is not less than the amount of infringer's profits as a minimum even when the plaintiff fails to prove the amount of damage. The Patent Act also provides that the patent owner may claim the usual amount of patent license royalty as the damages. Since the Korean legal system does not know punitive damages, these assumption provisions were not enough to protect the patent owner.
The new law further ameliorate the patent owner's burden of showing damages by allowing calculation of damages based on the number of unit product sold by the infringer and the patentee's cost accounting. This new provision is a codification of a case law. (Art. 128(1))
