Ion thrusters are used in communication satelites and for spacecrafts main propulsion. This system
consists on ions expulsion so as to create the impulse, and can provide higher speeds than other
types of devices. This article has the objective to make a foresight analysis of Ion Propulsion
through an anteriority research on Espacenet® patents database. In all, 58 patents filling were
found in the research field between 1995 and 2015. With the search for priors, it was possible to
analize the main depositors, the most active countries and the research trend over the recent years.
The study showed that although active for many decades, this field still has room for new research due to the small number of existing influential depositors, showing a result of 58 deposits in a 20
years period of study.
