Supermarket giant Tesco PLC (LSE:TSCO) and German-owned discount chain Lidl GB Ltd have begun a High Court fight over the use of a yellow circle logo, according to news reports.
Lidl is claiming that 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.
Barrister Benet Brandreth, who is leading Lidl's legal team, said the "protection available to Lidl's core brand" is "at the heart of this claim", the Retail Gazette reported.
Meanwhile, Hugo Cuddigan, who is leading Tesco's legal team, said that to establish infringement Lidl would need to satisfy the judge that "creating a yellow circle involves sufficient artistic skill and labour to comprise the author's own intellectual creation", it said.
The hearing at the High Court in London began on Tuesday and is due to end next week.
