1 case as defendant.
Lululemon Athletica Inc., commonly known as Lululemon, is a Canadian-American multinational athletic apparel and accessories retailer. Founded in 1998 by Chip Wilson, the company is headquartered in Vancouver, British Columbia, and incorporated in Delaware, United States. Lululemon is a publicly traded company on Nasdaq under the ticker symbol LULU. As of fiscal year 2024, the company reported revenues of US$10.6 billion and employs approximately 39,000 individuals globally.
Lululemon designs, distributes, and retails technical athletic apparel, footwear, and accessories for activities such as yoga, running, and training. Its major product lines include sportswear, lifestyle apparel, shoes, and accessories, often associated with the "athleisure" market. The company operates through a global network of over 700 company-owned stores, digital e-commerce channels, and select wholesale partners.
Based on tracked patent litigation, Lululemon USA Inc. operates as an active two-way litigant rather than a Non-Practicing Entity (NPE). The company has been involved in one case as a plaintiff and one as a defendant, both directly against competitor Nike, Inc. These cases, spanning the U.S. District Court for the Southern District of New York (S.D.N.Y.) and the Patent Trial and Appeal Board (PTAB), indicate strategic engagement in intellectual property disputes with other operating companies.
Notable cases include Nike's lawsuit against Lululemon in S.D.N.Y., filed in January 2023, alleging infringement of Nike's Flyknit technology patents by Lululemon's footwear, including its Chargefeel, Strongfeel, and Blissfeel sneakers. A jury initially found infringement and awarded Nike damages, but a judge later overturned the verdict in April 2026, ruling two of Nike's patent claims invalid for obviousness. Separately, Nike also filed a lawsuit in January 2022, accusing Lululemon of infringing six patents related to its Mirror Home Gym and associated mobile applications, a product Lululemon acquired in July 2020. The PTAB case reflects Lululemon challenging Nike's patents, with some Nike claims related to the Mirror dispute canceled by the PTAB in May 2024.
A jury initially found for Nike and awarded damages, but the district court granted a post-trial motion for judgment as a matter of law for Lululemon, ruling US8266749 invalid based on obviousness and overturning the jury's verdict.
