The Korean Intellectual Property High Court (IPHC)’s decision issued on October 31, 2024 (Case No. 2023 Na 11276) is attracted significant attention as the first IPHC ruling to award punitive damages for willful patent infringement. This decision is expected to serve as an important precedent and help shape the criteria for determining punitive damages in future cases.
Punitive damages for willful patent infringement were introduced through the amendments to the Korean Patent Act on January 8, 2019 (effective July 9, 2019), with addition of Articles 128(8) and 128(9). Under these provisions, courts may award up to three times the actual damages in cases of willful infringement. In this case, the Court made three determinations:
First, the Court held that even if the acts of infringement spanned the effective date of the revised Patent Act (July 9, 2019), the provisions for punitive damages could still be applied to the portion of the infringement that occurred after that date.
Second, with respect to the definition and criteria of “willfulness,” the Court held that willfulness is established if the infringer continues the infringing acts with an awareness of the possibility that such acts may constitute patent infringement. The Court further clarified that “intent” includes not only direct intent but also conditional intent – where the infringer recognizes the risk of infringement and nonetheless accepts that risk.
Third, the Court examined the factors relevant to determining the amount of punitive damages. Under Article 128(9) of the Patent Act, eight factors are listed to be considered in assessing the appropriate level of punitive damages. In the above case, the Court awarded punitive damages in the amount approximately twice the actual damages, taking into account the following considerations: ① the defendant’s superior economic and transactional position relative to the plaintiff; ② the defendant’s direct intent in carrying out the infringing acts; ③ the significant economic gain realized by the defendant through the infringement; ④ the prolonged and repeated nature of the infringing acts; ⑤ the defendant’s financial condition; and ⑥ the defendant’s failure to take appropriate steps to mitigate or remedy the harm caused.
This decision is noteworthy as it represents the first instance in which a Korean court has applied punitive damages to a case of willful patent infringement. It is expected to serve as a foundational precedent, contributing to the development of a clearer legal framework for evaluating willfulness and determining the appropriate amount of punitive damages in future cases.
Moreover, although the Patent Act in effect at the time limited punitive damages to three times the actual damages, recent amendments effective as of August 21, 2024, have increased the statutory cap to five times the actual damages under Article 128(8). This legislative change is anticipated to further strengthen the protection of patent rights and enhance deterrence against intentional infringement.
