Patent Infringement Suit Over Yoga Pants

By Sarah Robertson, Susan Progoff, Fara Sunderji and Jena Tiernan of Dorsey & Whitney LLP

Lululemon, maker of fashionable yoga and exercise pants with an adjustable waistband, recently sued Calvin Klein Inc. and its supplier, G-III Apparel Group Ltd., in the United States District Court for the District of Delaware for infringement of three design patents covering Lululemon's adjustable waist pants.

As it is unusual for a patent infringement suit to involve an article of clothing, particularly something as fashionable as Lululemon's yoga pants, the case attracted a great deal of attention. A confidential settlement agreement reached before either defendant responded to the complaint has prevented the parties from disclosing details of the dispute's resolution.
