This Practice Note summarises the main types of legal action that can be taken against the UK trade in counterfeit goods, the pros and cons of each, and includes some practical tips for brand owners. It covers actions by the authorities, including customs, Trading Standards (TS) and the police, as well as civil actions and private criminal prosecutions by right holders. In some countries, it is also possible to bring administrative actions against infringers, but these are not dealt with here. This Practice Note focuses on counterfeiting (meaning trade mark-related offences), but also touches on piracy (copyright-related offences) and offences relating to registered designs.
