South Korea

South Korea has a patent act named the Republic of Korea-United States Free Trade Agreement (KORUSFTA). Article 17.10.4 of AUSFTA has an identical element in article 18.9.4 of KORUSFTA.

Moreover, till every applicable patent on the label word product has expired. After NAFTA evoked restrictions, whenever a medicine manufacturer fills an application for a fresh product. Then it again delivers a Notice of Allegation(NOA) declaring that none of their patents has been violated.


To harmonize with international norms, the Australian government made specific alterations in its laws. A fresh section 26B has an arrangement in the Therapeutic Goods Act,1989. According to 26B, the applicant needs to certify that their product is not infringing on existing patented products. Further, the Australian administration authorized anti-evergreening adaptations in 26C and 26D Sections of Therapeutic Goods Act 1989. These amendments are created to avoid patent owners from falsifying the court system for extending their patents. Further, the goal of 26C and 27D is to curb patent owners to get an extension of their patents.
