On July 11, 2016, Adidas filed suit against Skechers in the U.S. District Court in Portland, Oregon for willful infringement of two patents related to Springblade, a shoe design intended to help propel runners move forward. Adidas accused Sketchers of developing its Mega Flex shoes as "takedowns" that copy the Springblade technology without the cost of creating it. Adidas is seeking an injunction against any infringement and triple damages.
This is Adidas' second lawsuit against Skechers in less than a year. Last September, Adidas filed suit against Skechers for illegally copying the design for its classic white Stan Smith tennis shoes. Adidas was awarded a preliminary injunction in February 2016 and it scheduled for a jury trial in May 2017.
The patents at issue are U.S. Patent Nos. 9,339,079 and 9,345,285, both issued in May 2016.
