In March 2010, former group member Mutya Buena applied to the European Trademarks Authority for ownership of the group's name. The application was submitted amid the controversy of Buchanan's departure, in which Buena insisted that "the Sugababes have ended" without a founding member still in the group. It was confirmed that Buena had obtained rights to use the name on paper, cardboard and goods; namely stationery, paper gift wrap and paper gift wrapping ribbons. In the same month the group was dropped by Roc Nation, due to poor sales of "Sweet 7".
