In early 2015, a European pharmaceutical company that sells a globally well-known pain relief drug discovered a drug with the same active ingredient and a similar name circulating on the Vietnamese market. In what the European company believed was a clear instance of palming off, the drug's packaging also used colours and design elements similar to the packaging of the well-known drug. However, pursuing a trade mark infringement charge was a dead end, as the Vietnamese drug's name had already been successfully registered as a trade mark.
