Cadbury's Dairy Milk range has long been associated with a particular shade of purple, so it's no surprise the chocolate giant has been looking to protect it. In a court case almost a year ago, Cadbury successfully managed to prevent other chocolate companies using the colour - specifically Pantone 2865c - on wrappers and packaging for their products.

That controversial decision has been overturned today in UK's Court of Appeal. Swiss firm Nestle has won their appeal against Cadbury, potentially giving other companies the opportunity to use the familiar purple colour for themselves. Judges ruled Cadbury's request for exclusive use of Pantone 2865c did not provide the necessary detail or comply with the criteria for registering a trademark,

A Cadbury spokesperson told BBC "we are disappointed by this latest decision but it's important to point out that it does not affect our long held right to protect our distinctive colour purple from others seeking to pass off their products as Cadbury chocolate." The spokesperson also said the company will now examine the ruling and possibly lodge an appeal to the appeal.

Cadbury is currently owned by Mondelez International, Inc., the company that emerged after previous owners Kraft Food split into two different groups last year. The group also oversees snack brands Milka, Oreo and Toblerone.
