Giant Australian wine brand Yellow Tail has has entered into a trademark battle with a US wine company over its wallaby logo. Family-owned Casella Wines, which produces Yellow Tail, has launched legal action to stop The Wine Group from using a kangaroo on the label of its brand 'Little Roo'. Casella Wines argues that American consumers will not be able to distinguish the difference between the two marsupial icons, which are both ‘oriented the same direction’ on the label.
