Lululemon, maker of yoga apparel, claims that Calvin Klein and G3 Apparel Group LTD infringed on three U.S. patents for their popular yoga pants.
In a July letter, Lululemon warned Calvin Klein that its knee length running tights marketed under the Performance brand violated all three patents, including two issued in June. G-III responded to the letter within weeks.
Lululemon and Canadian company with 108 stores across the united states, has filed a lawsuit seeking damages and injunctions on further production of the product.
