10 May 2016How would patenting affect independent drugmakers?

Despite Gilead's licensing agreement to make Sovaldi affordable in developing countries, patient and public interest groups, who are against its patenting, argue that the licensing deals would not ensure access to several high-burden middle-income countries that were not covered by the voluntary license.

Further, patenting would affect Indian pharma companies that were planning to manufacture the cheaper version of the drug independently.
