A U.S. federal judge has overturned a jury verdict that found Lululemon infringed a Nike sneaker patent, wiping out a $355,450 damages award and ruling that the asserted patent claims are invalid as obvious. The decision is a major legal win for Lululemon in an ongoing feud over knit footwear technology used in its Blissfeel, Chargefeel and Strongfeel women’s running shoes.
What The Judge Actually Decided
In a March 31, 2026 opinion, U.S. District Judge Arun Subramanian in Manhattan granted Lululemon’s motion for judgment as a matter of law, holding that the claims of Nike’s U.S. Patent No. 8,266,749, covering methods of manufacturing knit sneaker uppers, are invalid for obviousness under U.S. patent law. That ruling overturns a March 2025 jury verdict that had found Lululemon infringed the ’749 patent and awarded Nike $355,450 in damages, far below the roughly $2.8 million (about 5% of shoe revenues) Nike originally sought.
Judge Subramanian concluded that, in light of prior art, the patented manufacturing method would have been obvious to a skilled technician, meaning Nike cannot enforce those claims against Lululemon and is not entitled to any damages.
The court also rejected Nike’s bid to increase the now erased award, closing the door, for now, on monetary relief in this case. How We Got Here: Nike v.
Lululemon Over Flyknit Inspired Tech The dispute dates back to January 2023, when Nike sued Lululemon, alleging that its Blissfeel, Chargefeel and Strongfeel sneakers unlawfully used knit upper technology covered by several Flyknit related patents.
A New York jury later found that Lululemon infringed the ’749 patent but did not infringe a second asserted patent (U.S. Patent No. 9,375,046), already narrowing Nike’s claims. Even at that stage, damages were modest: the jury’s $355,450 award fell well short of Nike’s requested royalty on Lululemon’s shoe revenues…
