During the last two decades cellulosic nanomaterials have been the subject of much research around the world.Moreover, in the last few years, increasing industrial interest on the field enabled the setting-up of the firstfacilities producing commercial quantities of nanocelluloses; whereas a number of inventions involving cellulosenano-objects are claimed every year. In this context, the current article describes the recent evolution (from 2010till 2017) of published patents which explicitly include in their title, abstract and/or claims references to cellulosenano-objects such as cellulose nanocrystals, cellulose nanofibrils and bacterial nanocellulose. Resultsevidence the astonishing increase in nanocellulose patents since 2010, and specially within the last three yearssurveyed (i.e. 2015?2017), when published documents accounted for ca. 70 % of the total number of patentspublished since 2010. Besides patent timelines, data is analysed in terms of patent owners, countries of application,and citing number.
