Nike on Wednesday filed a lawsuit accusing Lululemon of patent infringement over the fitness apparel maker’s at-home Mirror fitness device and related mobile applications.
The suit was filed in Manhattan federal court.
A spokesperson for Lululemon didn’t immediately respond to CNBC’s request for comment.
Lululemon shares were down about 3.5% Wednesday afternoon. Nike shares were last down around 2% amid a broader market sell-off.
Prior to filing the lawsuit, Nike said it notified Lululemon of the alleged infringement and that the leggings maker dismissed Nike’s claims.
