Fig. 1 — Patenting trend by number of granted patent families and the total patent families. The overall filing trend in the last 30 years for NTDs reveals an increasing trend between 1985 and 2014. Following the intense growing period between 1985 and 2008, there is no steady increase in the number of total patent families, but there is a slow but continous growth in the number of granted patent families. Patent applications are not published until after 18 months, this explains why no data is presented after 2014
