Cadbury lost a 9-year trademark battle to protect the iconic purple of its candy wrappers. The color, better known as Pantone 2685C, is the distinctive purple used by Cadbury to wrap its milk chocolate candy since WWI.
The Appeals Court in the UK stated the claims in Cadbury's trademark application were too broad and they refused to grant the protection. Rival candy company Nestlé has been a driving force behind the battle and is pleased with the outcome. The Nestlé "Wonka Bar" is packaged in a similar color.
