Patent and Drug Market Approval Linkage in Korea


The FTA between Korea and USA includes provisions regarding the patent drug market approval (MA) linkage. Pursuant to the KORUS FTA, Korea already amended the Drug Act and is preparing enactments of further necessary provisions in the Drug Act and the Patent Act in order to fully implement the FTA. The full system for patent drug market approval linkage will be implemented on March 15, 2015.

1. Green List – the Korean version of Orange Book


When a company of a new drug application (NDA) has obtained a drug market approval (MA) from KFDA, the NDA holder must list patent information in the patent list (“Green List”) of KFDA. The Green List is similar to the Orange Book in the U.S., but is not the same. The deadline to list is 30 days from the receipt date of MA.

Unlike the Orange Book in the U.S., a NDA holder must list patents with the claim-by-claim basis in the Green List. Therefore, an applicant must specify every claim that covers the approved drug product and further an applicant must submit detailed explanation between each claim and the approved drug to KFDA.

2. ANDA Applicant’s Certification on Listed Patents


Like the HWA, an applicant of a generic drug application (ANDA) must submit a certification regarding listed patents of Green List to KFDA. The patent certification is similar to those of HWA. For example, an ANDA applicant must file a Para. IV certification if he wants to launch a generic drug before the expiry date of listed patents. In such a certification, the generic drug applicant must provide a detailed statement demonstrating that the listed patent is invalid or that the generic drug does not infringe the listed patent.

3. Notice to the NDA holder and the Patentee


Like the HWA, an ANDA applicant with Para. IV certification must notify the fact that an application for generic drug approval has been filed and the filing date of the application to the product approval holder and patent owner within 7 days of the application filing date. The obligation to notice will apply to an ANDA applicant who will launch their product before the expiry date of term of the listed patent. Otherwise, this provision does not apply to generic applicants who intend to launch their drug after the expiration of the listed patent.

4. Others to be Decided this year


The patent MA linkage system in Korea may be similar to the HWA system of the U.S. We envision that details will be quite different from those of HWA. However, we don’t have concrete information yet because the current law just has portions of necessary provisions. The FTA of Korea and U.S. set the deadline to implement a whole system of patent MA linkage in Korea: March 15, 2015. Therefore, with certainty, we will have details for remaining items within this year. We will immediately post them when they are available.
