Kit Kat has been told it doesn't legally own the shape its famous chocolate bar.
The European Court of Justice has ruled Nestle can't trademark the look of its four-fingered wafer.
The confectionery giant had been locked in a legal battle, including with rival Cadbury, for the last sixteen years.
The European Court of Justice has also told intellectual property officials to reconsider whether its shape can still be considered an EU trademark.
The court heard how the chocolate bar wasn't well-enough known in all member states - in a battle with the maker of a similar treat in Norway.
