Court orders TWC to pay mobile operator over VoIP patent dispute

A US court has ordered Time Warner Cable to pay Sprint $139 million for infringing its voice over IP (VoIP) patents.

Sprint brought the lawsuit against Time Warner, now part of Charter Communications, in 2011, accusing it of breaching its intellectual property for the IP calling.

Last week, a Kansas City jury ruled in favour of Sprint, finding that TWC had willfully breached the patents, giving a judge scope to increase the damages by up to three times the amount.

According to Bloomberg News, which first reported the outcome of the trial, TWC will look to appeal against the verdict.

The lawsuit is one of a number of cases filed against cable companies by SoftBank-owned Sprint over its VoIP patents. Comcast successfully won a $7.5 million countersuit against the charges in 2014, a verdict that was affirmed by the appeals court in January, although another case is set to begin next week.

Sprint also brought a suit against Cox, but this was dismissed by a Delaware judge. Sprint appealed this verdict, with the litigation currently ongoing. 

The mobile operator also challenged Vonage in 2007, bagging an $80 million settlement, and won an undisclosed amount from Paetec Holding in 2008.
