Nestle

Bloomberg reports that Cadbury has lost a court fight with Nestle in the United Kingdom Court of Appeal to exclusively trademark the purple packaging of chocolate bars. Nestle "overturned an October 2012 decision that ruled the color purple was distinctive to the maker of Dairy Milk bars. The ruling allows Nestle, and any other confectioners, to sell chocolate products with the same colored wrapping," Bloomberg also reported.

The Washington Post has a fun slideshow of other businesses that have been able to trademark color hues as distinctive to their products in the marketplace: http://www.washingtonpost.com/business/economy/name-that-color-cadbury-p...
