TQ Delta LLC

TQ Delta LLC is a technology development and licensing company specializing in communications industry solutions, headquartered in Austin, Texas. While its website copyright dates to 2015, the company effectively began operations in 2012 with the acquisition of a significant patent portfolio from Aware, Inc., a pioneer in multicarrier communications technology. TQ Delta LLC is characterized as a patent assertion entity (PAE) or technology development and licensing firm, focusing on monetizing its intellectual property.

The company's core operations revolve around its extensive portfolio of patented inventions, primarily covering Digital Subscriber Line (DSL) and Multimedia over Coax Alliance (MoCA) technologies. Many of these patents are considered standard-essential patents (SEPs) within global telecommunications standards established by the International Telecommunication Union (ITU). TQ Delta aims to license these technologies to companies worldwide whose products and services utilize these communication standards.

TQ Delta LLC's patent litigation posture is that of an NPE actively asserting its acquired portfolio. According to our tracked cases, TQ Delta LLC has appeared as a plaintiff in 1 case and as a defendant in 0 cases, with all tracked activity in the Delaware District Court. This aligns with its business model of licensing and enforcing its patent rights.

Beyond the single tracked case, public records indicate TQ Delta LLC has been involved in numerous other patent infringement lawsuits against major telecommunications companies. Notable past and ongoing litigations have included actions against companies such as CommScope (including its subsidiary 2Wire Inc.), DISH Network, Comcast, Cox Communications, Time Warner Cable, Verizon, ZyXEL Communications, and ADTRAN. These cases, often filed in plaintiff-friendly venues like the Eastern District of Texas and the District of Delaware, typically assert infringement of DSL and MoCA related patents. For instance, in 2019 and 2020, Delaware federal juries found 2Wire Inc. (now part of CommScope) infringed TQ Delta's DSL patents. The company has also achieved significant patent wins in the UK, including a judgment against ZyXEL Communications UK Ltd concerning DSL technology.
