Cadbury UK Ltd v The Comptroller General of Patents Designs and Trade Marks

Trade mark – Mark. The Chancery Division dismissed Cadbury's appeal against the decision of the hearing officer to refuse a request to delete a trade mark that included the use of a certain shade of purple in the packaging of goods. The hearing officer had not made a material error of principle in not accepting that the mark in issue was a series mark, and Cadbury's proposal was fundamentally flawed.
