Canadian activewear brand Lululemon Athletica is suing Under Armour in the United States, alleging that the US sportswear giant copied the design of one of its sports bras.
Lululemon is suing for trademark infringement relating to its Energy Bra design, which it believes has been copied in four Under Armour designs, the Washington Post has reported. The design is patented by Lululemon in the US and the lawsuit has been filed in the state of Delaware.
The design features four straps, crossed at the back, which the brand’s website claims “does it all”. In its filing, Lululemon says: “Under Armour’s unauthorized acts have caused and will continue to cause irreparable damage to Lululemon and its business.”
In a statement to the Washington Post, Under Armour said the company “takes the intellectual property rights of others very seriously.”
