The 2011 International Property Rights Index (IPRI) is an international comparative study that measures the significance of both physical and intellectual property rights and their protection for economic well-being. In order to incorporate and grasp the important aspects related to property rights protection, the Index focuses on three areas: Legal and Political Environment (LP), Physical Property Rights (PPR), and Intellectual Property Rights (IPR). The current study analyzes data for 129 countries around the globe, representing ninety-seven percent of world GDP. Of great importance, the 2011 gauge incorporates data of PR protection from various sources, often directly obtained from expert surveys within the evaluated countries.
