Cuthbert on trial: how supermarket IP wars make for legal drama

Episode #1912 May 2025

From Aldi’s beloved Cuthbert to Tesco’s controversial Clubcard branding, supermarket intellectual property (IP) disputes have become more fiery than bargain-hunters on Black Friday. These clashes, involving significant financial risks and courtroom showdowns have immortalised terms like ‘Free Cuthbert’ and ‘Caterpillar Wars’ in popular culture. Even as court battles are settled, and headlines fade, the memes endure, demonstrating how IP conflicts can deeply impact a supermarket’s brand reputation and consumer perception.

Beginner summary

Intellectual property, or IP, protects creations like names, logos, and designs. The Intellectual Property Office (IPO) oversees trademarks in the UK, granting businesses a legal shield for names, logos, and other identifying marks. A trademark is a distinctive sign, like Lidl’s familiar blue-and-yellow logo or Marks & Spencer’s (M&S) Colin the Caterpillar, protected against unauthorised use. Legal conflicts often arise when lookalike packaging or branding leaves shoppers unsure which store or manufacturer is responsible for a product, highlighting why IP matters in retail.
