Judges ruled in favour of Huawei, which had sought an EU-wide trademark for a logo it wanted to use, but the fashion house said it was too similar.
The EU General Court in Luxembourg ruled on Wednesday that the logos “share some similarities but their visual differences are significant”.
It found that Chanel’s logo had more rounded curves and thicker lines.
In 2017, the Chinese technology firm had applied for EU trademark protection for a logo it would use for computer hardware.
French firm Chanel opposed the bid, arguing the two vertical intertwining semi-circles were too similar to its protected logo, which it uses to sell make-up, perfumes, clothing and accessories.
