The US brewing giant Anheuser-Busch has taken the unprecedented action of taking Portugal to the European Court of Human Rights, saying that a ruling by the country's authorities over the Budweiser trademark had infringed its rights.

According to a report in the Financial Times today, the company argues that a trademark should be considered a possession under human rights laws.

It says that a ruling against it in the long running battle with Czech company Budejovicky Budvar over the "Budweiser" brand name had infringed its rights to "peaceful enjoyment of its possessions".

Four years ago the Portuguese courts set aside Anheuser's registration of the trademark.
