Applying patent intelligence to explore the technology evolution

Voice data transmission is an important revenue source for mobile communications operators. VoLTE is the technology driver of the growth for 4G LTE voice data transmission. The first wave of VoLTE-enabled devices became commercially available between 2014 and 2016. To understand the global development of VoLTE technology, this study examines VoLTE patent portfolios and identifies area for VoLTE patent applications and commercialization. We recommend that mobile communications companies establish a competitive advantage with VoLTE technology leadership prior to the year 2018. All manufacturers should act expeditiously to develop patent protection for the next generation of voice communications technology. This research provides mobile-telecom service providers, mobile network operators, and terminal equipment manufacturers with an understanding of the VoLTE technology frontier and the competitive status of emerging innovations.
