Sonohm Licensing LLC, a plaintiff affiliated with Texas monetization firm IP Edge LLC, has followed up its February case against Tangent Computer (3:20-cv-01511) with March suits against Avalue Technology (1:20-cv-00856), CONTEC (1:20-cv-00422), MilDef (1:20-cv-00423), Nex Computers (4:20-cv-02150), Superlogics (1:20-cv-10642), and VTech Holdings (Leapfrog Enterprises) (4:20-cv-02148), filed in a variety of judicial districts across the US. The NPE asserts in each complaint two patents generally related to wireless communication, with infringement allegations trained on a wide variety of devices alleged to use Bluetooth 4.0. After the February dismissal with prejudice of a declaratory judgment action brought by Amazon and the March dismissal with prejudice of an affirmative case against Mattel, the new suits join one open case in the campaign, active in the District of Utah against Juniper Systems.
