From 10-Q

To date we have filed patent infringement litigation and sought licenses from twelve companies and related distributors, resulting in one royalty bearing license and settlement agreement with one defendant, and four license and settlement agreements covering five defendants. We currently have two active complaints in the U.S. District Court for the Northern District of California and four active complaints in the U.S. District for the Southern District of California. We expect to file future complaints against additional companies. We are in early negotiations with other defendants, and are confident regarding the prospects for future license revenues from the Nunchi portfolio.
