You'd immediately say Bounty, right?
Well apparently the Bounty bar isn't distinctive enough to warrant a European community trademark. The manufacturer, Mars, applied for a trademark on the basis of its unique "three dimensional nature" which was granted in 2003, but overturned following an appeal by manufacturer Ludwig Schokolade.
The European Court also said that a survey carried out by Mars in six of the then 15 member states - United Kingdom, Belgium, France, Germany, Italy and the Netherlands - did not necessarily mean the Bounty Bar's shape was regarded as a unique selling point throughout the EU.
What do you think? Can a manufacturer copyright a bar's shape - assuming that it doesn't carry a trademark or logo?
