Microsoft (3:18-cv-00222) has filed a complaint against Iron Oak Technologies LLC, seeking declaratory judgments of noninfringement of two patents that the NPE has asserted in litigation against multiple defendants since November 2016. Microsoft pleads a justiciable controversy between the parties based on a letter that it received from Iron Oak, attached to the complaint, alleging infringement and identifying five Iron Oak patents “most relevant to [Microsoft’s] activities”, as well as on Iron Oak’s infringement allegations in cases already filed against Dell and HP, which refer to “Microsoft’s products, services and technology, including Automatic Update and automatic network connection features”.
