As software contains algorithms, it is deemed to be part of the field of mathematics; hence, software cannot be protected by patents in Indonesia. However, one way for the Indonesian Intellectual Property office to grant software patents in Indonesia is if the application has been patented in other nations, which have ratified the Patent Corporation Treaty (PCT). Therefore, in accordance to the regulations under the Patent Cooperation Treaty, a software will have a regional protection among the participating entities of World Intellectual Property Organization (WIPO).
