May I request an extension of the patent term?
TIPO will authorize an extension of up to five years in the case of there being a certain period of time during which the patent right cannot be utilized after it is granted and the patent right is in the field of pharmaceuticals or agricultural chemicals, or the manufacturing process, and the patent owner is required to take some specific action or obtain permission, such as permission required under the regulation on public safety.
It is necessary to file an application in order to extend the invention patent right. However, the decision as to whether the patent can be extended will ultimately be rendered by the patent examiners.
