Microsoft is ramping up its patent fight with InterDigital Inc by filing a lawsuit in the US courts.
The latest match-up in the long patent battle between the two sees Microsoft accusing InterDigital of flouting US antitrust law by not keeping a promise to properly license technology essential for mobile communications, according to Reuters.
Triple those damages
The ITC judge has already stated that there is evidence Microsoft used "reverse patent holdup". This is what happens when a company uses technology covered by a patent but then refuses to pay up.
When it comes to a settlement in the new case brought by Microsoft, it is asking for the court to triple any damages it awards and stipulate that InterDigital cease enforcing patents. As with any patent dispute, this one looks set for the long haul.
