Sublicensing in the context of intellectual property rights refers to a license granted by a licensee to a third party under the authority granted to the licensee. Depending on a license strategy of the owner of the intellectual property rights, sublicensing can be an effective way of commercializing intellectual property rights. It is a type of technology transaction that evolves with a monetization of intellectual property rights. However, intellectual property laws do not include many provisions for sublicensing. Even where sublicensing provisions exist, they are not uniform across various forms of intellectual property rights, creating considerable uncertainty room in interpretation. Therefore, to enhance the potential for technology transactions through sublicensing, it is necessary to consider the sublicense system from an integrated intellectual property perspective, thereby contributing to technological and industrial development. Accordingly, this study proposes an integrated framework and policy direction for the sublicensing system.
