Nike and Lululemon have agreed to end a four-year patent dispute over Lululemon’s Mirror home workout technology, filing to dismiss the federal lawsuit with prejudice after a series of challenges to the patent claims asserted by Nike.
The companies told the U.S. District Court for the Southern District of New York that the case should be dismissed with prejudice, preventing Nike from bringing the same claims again. The filing did not disclose whether the companies had reached a financial settlement or any other agreement resolving the dispute. Nike declined to comment on the filing, while Lululemon had not provided further details when the dismissal was reported.
Nike filed the case in January 2022 against Lululemon Athletica, Lululemon USA and Curiouser Products, the business behind Mirror. The sportswear company alleged that the Mirror Home Gym infringed six patents covering fitness technology used to set exercise targets, track performance and allow users to compete with one another. Lululemon denied the infringement allegations. The case, Nike Inc. v. Lululemon Athletica Inc. et al., was filed under case number 1:22-cv-00082.
Lululemon acquired Mirror in 2020 for approximately $453 million, giving the company ownership of an interactive home fitness platform offering live and on-demand workout classes. The patent case subsequently became one part of a Peloton Has Sued Lululemon In Dispute Over New Apparel Line – Lawyer Monthly.
Proceedings in the Mirror case were paused in 2023 while Lululemon challenged Nike’s patents before the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board. The tribunal ultimately found relevant claims in five of the six asserted patents unpatentable. Nike pursued appeals from some of those decisions but suffered further setbacks at the U.S. Court of Appeals for the Federal Circuit.
In one of those proceedings, the Federal Circuit ruled in August that the Patent Trial and Appeal Board had correctly found challenged claims of Nike’s U.S. Patent No. 8,620,413 unpatentable. The appellate case concerned claims covering exercise and performance-monitoring technology, including systems using exertion levels and heart-rate information.
The dismissal also follows the end of a separate Nike patent case against Lululemon involving athletic footwear. A jury had awarded Nike $355,450 after finding infringement of one patent, but U.S. District Judge Arun Subramanian overturned that result in March 2026 after concluding that the relevant patent claims were invalid as obvious. The amended judgment awarded Nike no damages, and the parties later agreed to dismiss Nike’s Federal Circuit appeal.
The Mirror litigation brought major intellectual property firms into the dispute. Nike was represented by Michael Harris of Arnold & Porter Kaye Scholer, while Kyle Mooney of Morrison & Foerster acted for Lululemon.
The outcome illustrates how inter partes review proceedings before the Patent Trial and Appeal Board can reshape Peloton Has Sued Lululemon In Dispute Over New Apparel Line – Lawyer Monthly. Although Nike began the case by asserting six patents against Mirror, Securing Freedom-to-Operate Opinions – Lawyer Monthly removed much of the patent portfolio underpinning the original complaint before the district court reached a trial on the infringement allegations.
The dismissal with prejudice now closes the Mirror case without a public ruling on whether the disputed home fitness technology infringed any surviving Nike patent claims. It also ends another front in the intellectual property litigation between two major sportswear companies after the separate footwear dispute concluded earlier this year.
