New York, Aug 19 - Microsoft Tuesday sought stay on a court injunction which bars it from selling its popular Word document creation software in the US for violating a patent belonging to a Canadian company.

Toronto-based i4i had dragged Microsoft to court in 2007 for using its patented technology in the software without its permission.

In its ruling last week, the US District Court in Tyler, Texas, banned Microsoft from selling Word 2003, Word 2007 and future versions of the software that use i4i's technology without a licence.

The court also ordered Microsoft to pay $290 million to i4i and directed it to comply within 60 days.

In an emergency motion filed with US Court of Appeals for the Federal Circuit Tuesday, Microsoft requested it to put the injunction on hold pending appeal.

Microsoft contended that i4i was not entitled to the injunction.

The Microsoft motion said: 'It is undisputed that i4i does not have a product that could fill the gap left in the market by the injunction; rather, i4i's products run as add-ons to Word.
