Function versus identity
A shape that gives a product its function or value is hard to register, because competitors need to use it too.
A long running dispute over whether the four finger shape of a chocolate bar can be protected as a trade mark.
Nestlé sought to register the shape of its four finger KitKat as a trade mark. Mondelez, which owns Cadbury, opposed the application.
Nestlé applied to protect the three dimensional shape of the bar, not only its name or logo.
Mondelez argued that the shape was common in the trade and could not identify a single source.
The courts examined whether consumers saw the shape alone as a sign of trade origin, not simply as a product feature.
The shape was not accepted as a registered trade mark in the relevant markets, and the dispute became a reference point for shape marks.
A shape that gives a product its function or value is hard to register, because competitors need to use it too.
