Canadian sportswear brand Lululemon has filed a lawsuit against US retailer Costco, alleging the company is copying its apparel designs. The dispute centers on Kirkland Signature, Costco’s in-house sports wear brand, which bears a striking resemblance to Lululemon’s products.
Lululemon has provided court documents with images of similar-looking items from both brands, highlighting the alleged design similarities. These include tops and leggings bearing identical logos, color schemes, and styles. The company claims that Costco is profiting from its trademarked designs without permission.
The lawsuit marks a notable move for Lululemon as it seeks to protect its intellectual property rights in the market. Costco, on the other hand, faces potential financial losses if found liable for copyright infringement.
