Fast-fashion giant Shein lost a London lawsuit against rival Temu on Thursday after a British court dismissed its copyright infringement claims over the use of photographs of Shein products, delivering a setback to the company as it prepares for a potential Hong Kong stock listing.
The ruling marks the first major judgment in the London legal battle between the two fast-growing online retailers and comes as Shein targets a valuation of between $30 billion and $40 billion for its planned Hong Kong initial public offering.
The court dismissed Shein’s claims that Temu infringed its copyrights and upheld a counterclaim brought by Temu seeking damages related to product listings that were removed after Shein secured an injunction.
Shein said it was surprised by the decision and disputed the court’s conclusion.
“We do not believe that is the right outcome for brands and rights holders seeking to protect their copyright online,” a Shein spokesperson said.
The dispute centers on how the two companies use product imagery and compete for customers in the highly competitive global fast-fashion market.
Shein accused Temu at the beginning of the trial in May of breaching its copyrights “on an industrial scale.” It alleged that Temu used photographs of Shein products to promote copies of Shein’s own-brand clothing, allowing the rival platform to “piggy-back” on Shein’s established customer base and brand presence.
Temu denied the allegations, arguing that Shein was using the courts as a means of restricting competition.
The ruling does not end the wider legal conflict between the two companies in Britain. Temu has brought a separate counterclaim accusing Shein of violating competition law by requiring fast-fashion suppliers to enter exclusive arrangements. That case is scheduled to go to trial next year.
The competition-law dispute could have broader implications for the two companies’ business models because both rely heavily on large networks of manufacturers and suppliers to maintain extensive product ranges while keeping prices low.
Shein and Temu have built their international businesses around low-cost products and highly aggressive online marketing, rapidly expanding beyond their original markets into the United States, Europe and other regions.
Their competition extends beyond clothing. Both platforms sell a wide range of consumer goods, including accessories, household products and gadgets, and have increasingly competed for the same price-sensitive online shoppers.
The companies have also pursued litigation against each other in the United States, making the London proceedings part of a broader international legal confrontation.
Thursday’s ruling arrives at a sensitive point in Shein’s corporate development. The company is seeking a Hong Kong listing that could value it at between $30 billion and $40 billion, meaning legal disputes involving intellectual property and competition could attract greater scrutiny from investors and regulators.
The decision also highlights the challenges of online retailing, especially in protecting intellectual property in a business environment where product images, designs and listings can move rapidly across competing platforms.
The copyright case was aimed at protecting the value of Shein’s product imagery and brand assets. But as it turned out, Temu, by successfully defending the claim, now strengthens its position against one of its most direct competitors.
The next major stage of the London dispute will be Temu’s competition case against Shein. The outcome could determine whether Shein’s arrangements with suppliers comply with competition law and could add another layer of regulatory pressure to a sector already facing scrutiny over pricing, supply chains, intellectual property and the treatment of online sellers.
The ruling therefore provides Temu with an important legal victory, but the wider battle between the two platforms remains unresolved. With both companies continuing to expand internationally and challenge each other through courts in multiple jurisdictions, legal disputes are expected to remain part of their expansion in global low-cost e-commerce.
