The new Cuthbert Aldi has brought back Cuthbert the Caterpillar, the cake at the centre of a legal dispute with M&S, but with a slightly altered face. The discounter has been pushing Cuthbert’s return on social media, with images showing it now has white chocolate eyes, like the rest of its face. Its eyes used to be brown. Intellectual property experts say changes to the cake’s appearance could have a bearing on M&S’s High Court trademark infringement claim, which centres on its similarities to M&S’s own Colin the Caterpillar. While other supermarkets sell ‘caterpillar cakes’, such as Tesco’s Curly and Asda’s Clyde, IP experts noted as M&S announced its claim last month that those offered more visual differences to Colin than Aldi’s Cuthbert did.
