Trade mark – Mark. The appeal of the appellant company, Cadbury, against a finding of the Registrar of Trade Marks, failed. Cadbury had sought to delete one of two specifications in a mark that it owned, concerning the use of the colour purple in its chocolate products. The Court of Appeal, Civil Division held that the mark did not consist of a series of marks, and that it was not a permissible registration of more than one mark within a single registration.
