A European court has upheld the Berlin Zoo\'s copyright claim against a British firm that had sought to market products under the name \"Knut - Der Eisbaer\" — German for \"Knut - The Polar Bear.\" The General Court of the European Union in Luxembourg ruled Monday that British firm Knut IP Management Ltd.\'s product-line name too closely resembled the Berlin Zoo\'s earlier trademarked brand \"Knud,\" and could confuse consumers looking to purchase merchandise related to the zoo\'s most famous animal. Knut was hand-raised after his mother rejected him. He rose to stardom in 2007 as a cuddly cub, appearing on magazine covers, in a film and on mountains of merchandise. He died in 2011 after suffering from encephalitis.
