The characteristics of the intellectual property right(IPR) conflict with standardization. This is because standardization aims to achieve the common use of technology while IPRs aim to protect the proprietary right on technology. The license to use IPR should be granted so that standards can be used without an infringement. IPR policies have common characteristics in most parts of their contents and also different application methodologies. The ultimate object of IPR policy is to receive license grant. In this paper, significant typical IPR policies of main standardization organizations are comparatively analyzed. The overall objective of the IPR policy is to make strategic environment for license grant. IPR disclosure becomes the best practice to acquire license grant. With this practice, the action to licensing refusal becomes one of the main strategic factors of IPR policies.
