On September 11 2015, the Drug Administration of Vietnam (DAV) issued a decision to withdraw the marketing authorisations (MAs) for nine pharmaceutical products on the market. While this is a fairly routine occurrence, what was notable was that two of the drugs on the list had their MAs withdrawn as a result of patent infringement – one of the first times this has happened in Vietnam. The withdrawal makes a strong statement that Vietnam is getting serious about enforcing patent rights in the pharmaceutical realm.
