Delaware Jury Sides with McAndrews Client TQ Delta


McAndrews secured a complete victory for its client TQ Delta LLC, a technology development and licensing firm, when a Delaware federal jury found that 2Wire Inc. infringed three of TQ Delta’s patents related to Digital Subscriber Line (“DSL”) technology. 2Wire is a subsidiary of ARRIS Solutions, which was recently acquired by CommScope Inc.

The jury’s verdict was announced on May 23 following a nearly four-day trial in the United States District Court for the District of Delaware. After deliberation, the eight-member jury returned a favorable verdict on all eleven counts, finding that 2Wire infringed U.S. Patent Nos. 7,836,381, 7,844,882 and 8,276,048, that those patents were not obvious over prior art, and that two certificates of correction were not invalid.

The TQ Delta patents at issue in the litigation cover important memory sharing and noise protection capabilities for Digital Subscriber Line (DSL) modems and central office equipment, among other inventions. These patents are part of TQ Delta’s sizable worldwide patent portfolio for digital communication technology, including DSL. McAndrews also represents TQ Delta in related litigation for other patents and against other DSL equipment vendors.

“We are pleased with the jury’s decision affirming the strength and importance of our portfolio of inventions, which are the culmination of years of investment in standards development and communications technologies,” said Abha Divine, Managing Director of TQ Delta.

TQ Delta has supported continued development of DSL markets by maintaining a longstanding business strategy designed to ensure advancements in the technology. “The TQ Delta portfolio and investment in the field contribute to both the present and future of high-speed DSL connections around the world. We have already licensed several companies to practice the important inventions under our DSL portfolio and will continue to seek to license others,” said Divine.

Lead trial attorney, Peter McAndrews, explained that “The defendant’s strategy was to trivialize the important inventions at issue. We are pleased that the jury vindicated the inventors’ hard work and our client’s commitment to innovation.”

“This is an impressive victory for Peter and his team,” said Robert Surrette, president of McAndrews. “It is just another example of how IP specialist firms are so effective for their clients.”

The trial team included McAndrews attorneys Peter McAndrews, Tom Wimbiscus, James Murphy, Paul McAndrews, Anna Targowska, Rajendra Chiplunkar, and Ashley Ratycz.
