Supermarkets Tesco and Lidl have begun a High Court fight over the use of a yellow circle logo.
German discount chain Lidl says a trademark, and copyright, has been infringed, while Tesco has made a counterclaim. Lidl uses a yellow circle in its main logo, and Tesco uses one to highlight offers available to members of its Clubcard scheme.
A judge began overseeing a trial at the High Court in London on Tuesday. Mrs Justice Joanna Smith was shown images of logos, including a yellow circle, surrounded by a red ring, containing the word "Lidl"; a yellow circle, surrounded by a red ring, with no words; and a yellow circle without a red surround and the words "Clubcard Prices" in the middle.
