Luxembourg based-entity Via Vadis, along with co-plaintiff AC Technologies, is expanding its litigation campaign more than a year after its only previous case was dismissed. Amazon, Belkin, BlizzardEntertainment, BuffaloAmericas, D-Link Systems, and NETGEAR were recently sued by the entity. Each suit asserts three patents owned by AC and exclusively licensed to Via Vadis (7,904,680, 8,656,125, RE40,251). Defendants in the suits include both router manufacturers and Internet content providers. Peer-to-peer file distribution systems and services supplied or supported by defendants are accused of infringing the asserted patents. The patents-in-suit relate to redundant data storage across multiple storage devices and transmission of stored data between devices. Two of the asserted patents (‘680 and ‘251) were also asserted in the entity’s previous litigation, filed against Skype in 2011. That suit was filed concurrently with several international patent infringement complaints involving the same parties and technologies. The district court case against Skype was dismissed in January 2013. 8/22, Western District of Texas, 1:14cv00807, 1:14cv00808, 1:14cv00809, 1:14cv00810, 1:14cv00812, 1:14cv00813
