BlackBerry maker Research in Motion (RIM) has been ordered to pay £94.5m in damages after losing a US patent case.
A court in San Francisco upheld claims by Mformation Technologies Inc that RIM infringed on its 1999 invention for remotely managing wireless devices.
Mformation's software allows companies to remotely access employees mobile phones to perform software upgrades, change passwords or wipe data from phones that have been stolen.
The settlement was reportedly calculated by the judges at $8 (just over £5) for each of the the 18.4 million BlackBerry devices in use since the lawsuit was filed in 2008.
Amar Thakur, a lawyer for Mformation, said the software was essential to its business, a privately held company with several hundred employees.
He said: 'We believe it has been fundamental to the success of Research In Motion.'
RIM has denied it has done anything wrong and is considering an appeal. The company has been battling a loss of market share and was further hit by delays to its BlackBerry 10 mobile operating software, which was seen as key for it to compete with the iPhone and smartphones running Google's Android software.
