Nike sues Lululemon for patent infringement over Mirror Home Gym, fitness apps

Nike Inc. on Wednesday filed a lawsuit accusing Lululemon Athletica Inc. of patent infringement for making and selling the Mirror Home Gym and related mobile apps without authorization.

In a complaint filed in U.S. District Court in Manhattan, Nike accused its smaller rival of infringing six patents, including through technology that enables users to target specific levels of exertion, compete with other users, and record their own performance.

Nike, based in Beaverton, Ore., is seeking triple damages for Lululemon's alleged willful infringement, and a variety of other remedies.

Mirror gyms start at $1,895 CAD, according to Lululemon's website.

Lululemon said in a statement: "The patents in question are overly broad and invalid. We are confident in our position and look forward to defending it in court."

In a letter to Nike on Dec. 10, 2021, a lawyer for Lululemon said the Vancouver, B.C.-based company "respects intellectual property" even as it rejected Nike's claims.

Lululemon purchased Mirror in July 2020

Lululemon bought Mirror, an at-home fitness company with an interactive workout platform featuring live and on-demand classes, for about $453 million US in July 2020.

Athletic apparel makers have benefited during the pandemic as people forced to work or spend more time at home ditched dressier clothing for hoodies, leggings and other casual wear.

But Lululemon warnedlast month that the spread of the Omicron coronavirus variant could reduce sales of its apparel because of supply chain issues and potential store closures.

It also halved its fiscal year sales forecast for Mirror to a range of $125 million to $130 million US.

In late afternoon trading in New York, shares of Lululemon were down 4.5 per centat $363.62 US, while Nike was down 2.1 per centat $162.91 US.
