Software giant Microsoft finally lost its battle over Word patent with Toronto's i4i Inc.
Rejecting Microsoft's appeal, the US supreme court upheld the 2009 lower court order against Microsoft to pay $290 million in damages to the Toronto firm for infringing its patent.
The Canadian company had taken the software giant to court in the US in 2007 over violations of its patent in Word applications and won the case and got $290 million in damages in December 2009.
In its lawsuit, i4i had claimed that the world's biggest software company infringed on a patent granted to it in 1998.
The patent pertained to i4i's technology that can open documents using the XML computer programming language and manipulate complex data in electronic documents. The technology allows users to sort out and manage tons of information by turning complex documents into more accessible databases.
