Editor's note

It may come as a nasty shock for cheesemakers to discover that their produce, the recipe for which has often taken generations of skill and dedication to develop, cannot be protected by copyright. As Estelle Derclaye reports, a recent case, referred to the European Court of Justice, found that because it’s impossible to precisely identify the taste and aroma of cheeses, copyright law cannot apply. The same, she says, goes for the smell of perfumes.
