Abstract
Obtaining essential intellectual property rights (IPRs) is important for innovation competition in the network industry, where technical standardisation plays a critical role in development. In this study, we empirically investigate the determinants of essential IPRs for wireless communications standards by using the patent database. More specifically, we compare manufacturing firms’ and non-practicing entities’ (NPEs) technology strategies for essential IPRs. Our results indicate that manufacturing firms accumulate their technological capability in specific technology fields, whereas NPEs cover broader technology fields to keep their dominant position in the standardisation process.
