Essential intellectual property rights and inventors' involvement in standardization

Obtaining essential intellectual property rights (IPRs) is important for innovation and competition in the network industry, where technical standardization plays a critical role in development. In this study, we empirically investigate the determinants of essential IPRs for wireless communication standards using the patent database. In particular, we focus on the inventors' involvement in technical standardization by identifying and collecting their patent applications. (C) 2014 Elsevier B.V. All rights reserved.
