Lululemon claims Costco sold unauthorised and unlicensed apparel that uses knockoff, infringing versions of its patents.
Athleisure brand Lululemon has filed a lawsuit against Costco, alleging that the warehouse club chain sold lower-priced duplicates of its products.
ABC News first reported that Lululemon claims Costco sold unauthorized and unlicensed apparel that uses knockoff, infringing versions of its patents.
Costco’s Kirkland Signature private label has been accused of ripping off Lululemon’s popular designs, including scuba hoodies, Define jackets, and ABC pants.

It also alleges that the practice misled consumers into believing that the authentic supplier manufactures Kirkland-branded products and that the discount retailer failed to clarify this.
“As an innovation-led company that invests significantly in the research, development, and design of our products, we take the responsibility of protecting and enforcing our intellectual property rights very seriously and pursue the appropriate legal action when necessary,” a Lululemon spokesperson said in a statement.
