Nike Sues Lululemon for Patent Infringement

  • Nike alleged in a lawsuit that Lululemon is using its technology in its Mirror Home Gym and other apps.
  • The lawsuit comes amid yet another pandemic surge during which at-home fitness options have been in high demand.

Two fitness industry giants are now ensnared in conflict.

On Wednesday, Nike filed a lawsuit against Lululemon, alleging the latter’s sale and distribution of the Mirror Home Gym and other apps constitutes infringement of “several” patents.

In the complaint, which Front Office Sports reviewed, Nike detailed its history of fitness apps and workout technology that track athletes’ performance. The Oregon-based company alleges that Lululemon is now using the same technology that it developed.

On Nov. 3, Nike sent a letter to Lululemon informing it of the claim. Lululemon refused to stop production and sale of the products.

Nike is requesting not only that Lululemon stop making these items, but that it receive damages and “profits for any continuing post-verdict infringement.” 

Neither of the two companies immediately responded to requests for comment.

More Disputes

This isn’t the only time Lululemon has been embroiled in a dispute over intellectual property.

Peloton previously filed a lawsuit against Lululemon, alleging it had copied apparel designs. In response, Lululemon counter-sued.
