On March 27th, 2017 The international medical humanitarian organisation Médecins Sans Frontières (MSF) filed a patent challenge on the Hepatitis Cdrug Sofosbuvir with the European Patent Office (EPO) in an effort to increase access to affordable Hepatitis C treatment. MSF has joined Médecins du Monde (MdM) and other civil society organisations from 17 countries in simultaneously filing patent challenges on the pharmaceutical corporation Gilead’s monopoly on Sofosbuvir, in a bid to remove the barriers that prevent millions of people receiving treatment.
