On January 31, Nike filed a lawsuit in the United States alleging that Lululemon had infringed on its patents (Case No. 1:23-cv-00771).

About the Patents
Three US patents related to Flyknit technology are cited.
One of them (US8266749B2) is similar to the patent exercised against Adidas recently.
Method for producing a knitted upper
The underside hidden by the tube-shaped structure is exposed when the fabric is pulled, as the tube-shaped part separates.
A structure in which the center of the knitted upper is raised in a three-dimensional manner.
Nike has previously filed patent infringement lawsuits against Adidas and PUMA based on Flyknit-related patents. (Already settled.)
In January 2022, Lululemon, including its affiliated company Curiouser Products, was sued for patent infringement in the MIRROR business (in progress).
At that time, six digital fitness patents owned by Nike were utilized.
