In a further demonstration of how difficult it can be to register a shape as a trademark across the whole of Europe, Advocate General Melchior Wathelet has issued his recommendation to the ECJ that the shape of Nestle's well known KitKat bar should not be protected as a registered trade mark.

In his view, the problem is that the chocolate bar's shape is not sufficiently well known in all member states for the shape to merit trademark status.

While the Advocate General accepted that the four finger shape mark was sufficiently well known in Austria, Denmark, France,  Finland, Germany, Italy, the Netherlands, Spain, Sweden and the UK, he considered that it was not sufficiently well known in other member states such as Belgium, Greece, Ireland or Portugal (or at least insufficient evidence was provided that it was well known in those countries).

The recommendation by the Advocate General isn't binding, but usually such recommendations are followed by the ECJ. We'll have to see what happens, but so far it isn't looking good for Nestlé. After all, Melchior is a notoriously Wise Man.

Given the massive costs which have been incurred during this saga, it is likely to mean that we will see fewer attempts by other brands to register shapes in this way in the future.
