Arris has countered Sony’s patent infringement complaint with the U.S. International Trade Commission with its own filing to the agency.
The Suwanee, Georgia, cable industry vendor alleges that Sony’s “importation [of] certain consumer electronic devices, including televisions, gaming consoles, mobile phones and tablets, and network-enabled DVD and Blu-Ray players” is infringing on Arris patents.
An Arris representative declined to comment for FierceCable.

Arris says Sony is violating at least half a dozen patents including one that relates to a digital system for tuning broadcast signals, another for how air flows through an electronics chassis, and still another pertaining to graphical user interfaces.
Last month, it was revealed that Arris is being investigated by the ITC for possible patent infringements on pay-TV set tops and other equipment sold to Comcast, DirecTV and Genie.
The trade commission said in a statement that the probe is in response to a complaint filed by Sony Corp. The commission is looking to see whether Arris and its subsidiaries imported digital and satellite television products that infringe on Sony patents.
Having acquired Pace in 2015, Arris is the largest maker of pay-TV set tops.
The ITC is an independent, ostensibly bi-partisan, “quasi-judicial” U.S. federal agency that provides trade expertise to both Congress and the White House. The agency is charged with determining the impact of imports on U.S. industries and directs actions against what it determines to be unfair trade practices, including patent, trademark and copyright infringement.
