The High Court has held that an application by Cadbury to register the colour purple (pantone 2685C) for milk chocolate and drinking chocolate in class 30 in "Libertel" form satisfies the "representation" requirement under section 1(1) of the Trade Marks Act 1994. A "Libertel" form of mark is an application for the colour per se, not spatially delimited. The question was whether such a sign is capable of being represented on the register in a manner which enables third parties to determine the clear and precise subject matter of the protection afforded as required by section 1(1). The High Court has said that it can be, over-turning a previous decision of the UKIPO.
However, the High Court upheld an earlier ruling that a second application for the same colour purple "applied to the packaging of goods" was not registrable. This wording would allow the mark to take on a multitude of different appearances and extend protection to situations where other colours were also present. The formulation was worse than that considered by the Court of Appeal in an earlier ruling between the same parties (in which "the predominant colour" wording was rejected). A third application to register the same colour purple "applied to the whole visible surface of the packaging of the goods" had previously been deemed to meet the "representation" requirement by the UKIPO.
The decision arose in the context of oppositions to the applications brought by Nestlé. Assuming the decision is not appealed, it means that applications for a single colour per se or a single colour "as applied to the whole visible surface of the packaging of the goods" would satisfy the "representation" requirement.
It should be noted that the High Court (and earlier Court of Appeal) decision does not preclude applications for colours as applied to goods. Provided the application specifies unambiguously how the colour is to be applied to the goods, it should satisfy the representation requirement. In all cases, an internationally recognised colour code is required.
