DALLAS – Sayles Werbner is preparing to deliver arguments this spring before the U.S. Supreme Court in a closely watched patent infringement case that is being described as one of the country’s top patent cases to watch in 2015.

The national legal publication Law360 singled out Dallas-based Sayles Werbner in an article (subscription only) that identifies three different Supreme Court appeals among the nation’s most important patent cases of the year. Sayles Werbner attorneys Mark S. Werbner, Richard A. “Dick” Sayles and Mark D. Strachan represent Texas-based wireless technology company Commil USA LLC in its claims against communications technology giant Cisco Systems Inc. (NASDAQ: CSCO).

Sayles Werbner successfully represented Commil in a 2011 Texas trial against Cisco involving patents that cover wireless networking technology. Jurors found in Commil’s favor, awarding the company more than $73 million after prejudgment interest. Cisco appealed to the U.S. Court of Appeals for the Federal Circuit. The Federal Circuit’s controversial ruling held that patent indirect infringement defendants such as Cisco could avoid liability by simply claiming a belief that contested patents were invalid.

Sayles Werbner challenged the Federal Circuit’s decision since it contradicts the U.S. Patent Act, which holds that all issued patents are presumed to be valid. The U.S. Solicitor General and the U.S. Patent and Trademark Office filed a brief in support of Commil based on similar arguments before the Supreme Court granted Commil’s request for review.

In addition to the Sayles Werbner team, Commil is represented in the Supreme Court appeal by attorneys Leslie V. Payne, Nathan J. Davis and Miranda Y. Jones from Houston’s Heim, Payne & Chorush. The related cases are Commil USA LLC v. Cisco Systems Inc., No. 13-896, and Cisco Systems Inc. v. Commil USA LLC, No. 13-1044.

Sayles Werbner has an international reputation as a “go to” trial law firm in multifaceted business litigation, patent litigation, life-altering personal injury cases, and other areas of the law.
