SanDisk has filed two separate lawsuits in the U.S. District Court in Wisconsin, seeking unspecified damages and a permanent ban on three patent infringements accusing a total of 25 companies of using SanDisk technology in their flash storage products. The companies manufacture, sell and import USB flash drives, CompactFlash cards, multimedia cards, MP3 players and/or removable flash storage products.
In the first suit filed in federal court in Wisconsin, SanDisk accuses the defendants of infringing five patents, which are also at the center of the ITC complaint. The second federal court suit accuses the defendants of infringing on two additional patents, which are not part of the ITC action or the first lawsuit. The company also formerly asked the U.S. International Trade Commission to halt importation of the products into the United States.
