Patents are intangible property rights and are not easy to prove the facts and damages of infringement, so patent laws have special regulations to protect patent holders. The Patent Act revised in 2019 fully protects patent holders by introducing a punitive damages system to the extent of three times the amount of damages for infringement of patent rights or exclusive practice rights, revising the Royalty provisions for compensation, and establishing a duty to present specific behavior type for infringement. Specifically, the amount of compensation for the implementation fee that can be claimed to infringers of patent applications or patent rights has been changed from "usual" royalty to "reasonable" royalty, and the patent holder or the party denying the specific conduct of the infringement was required to present its specific conduct. In addition, the punitive damages system was introduced so that if the infringement of patent rights or exclusive rights is recognized as intentional, the amount of compensation could be recognized within a range not exceeding three times the amount recognized as damage. When determining whether an infringement is intentional, the extent of the infringement, the period and number of infringement activities, and the degree of economic benefits gained by the infringer were considered to strengthen the damage relief caused by infringement rights or exclusive practice rights. In this paper, the new regulations above were examined and the pros and cons of the new regulations were analyzed to contribute to the establishment of the correct system.
