TQ Delta LLC, a Techquity Capital Management, LLC subsidiary, has sued CommScope (ARRIS) (2:21-cv-00310) and Nokia (2:21-cv-00309) over the provision of DSL (digital subscriber line) equipment that complies with various DSL standards, including ADSL2/2+, VDSL2, G.bond, G.inp, G.vector, and G.fast. These Eastern District of Texas cases fall into a campaign that has been litigated before District of Delaware Judge Richard G. Andrews in two batches—one concerning DSL equipment and the other concerning Multimedia over Coax Alliance (MoCA) technology, a technology that enables media distribution over existing in-home coaxial cabling—since late 2013. More than 50 patents have been asserted, which Judge Andrews has divided up into multiple families for staged trials, two of which have resulted in jury verdicts favorable to TQ Delta, and which the PTAB has considered through nearly 30 petitions for inter partes review (IPR) filed.
