Delaware NPE Comserve Solutions LLC has filed its first litigation, over a family of two patents generally related to upgrading a mainframe computer system’s operating system (OS). The plaintiff accuses Dell (VMware) (1:21-cv-02196) of infringement through the provision of the VMware vSphere server virtualization software, with features for installing OS updates on virtual machines at issue.

Earlier this month, IPValue Management, Inc. (d/b/a IPValue) announced that it had acquired over 1,200 patent assets from the display business unit of Mitsubishi Electric. While that transaction is not yet reflected in currently available USPTO records, the recordation of another recent Mitsubishi Electric divestment to an NPE has just cropped up among assignment data. Meanwhile, Arigna Technology Limited, a hedge fund-backed NPE under the Atlantic IP Services Limited umbrella, has taken one of its multiple campaigns asserting former Mitsubishi Electric patents to the International Trade Commission (ITC).
