Patent, as a valuable collection of technical information, is gaining momentum as proxy measures of innovative activities and is ascribed a unique role in tracking the rise of emerging technologies. The last 30 years have seen a dramatic transformation of the world's manufacturing landscape, for instance, a greening development in the automotive sector. A typical example of this practice is the emergence of electromobility (e-mobility)-an integrated approach addressing issues from sustainable transportation to revolutionary driving behavior adopted to circumvent problems concerning both resources and pollution while meeting mobility demands. Since novel technologies covered by e-mobility are not yet entirely attainable in the market, the only metric particularly is patent data. However, a correspondingly bright light seems not to be shined on e-mobility patent research, even in the area of engineering. This paper employs bibliometric and sentenceby-sentence analysis coupled with visualization tools to illustrate how the patent examines e-mobility-oriented issues in a contextualized and multivalent way. The conclusion reached is that patent research on e-mobility still has more spaces to move up, not only in improving its efficiency in plotting evolution of technologies but with regard to interpreting patents across the historical background of the industrial revolution.
