A federal appeals court today upheld a $290 million judgement against Microsoft Corp. and issued an injunction that will prevent the sale of its popular Word software, according to AP. The court injunction is set to go into effect Jan. 11. Microsoft has said such a bar would prohibit the sale of all currently available versions of Microsoft Word and Microsoft Office. Microsoft had appealed a Texas jury verdict in favor of i4i Inc., a Toronto company. The jury found recent versions of Microsoft Word infringed on a software patent. Microsoft has said that it and the public will both suffer if Word goes off the market while the company devises a workaround. The court said the decision does not affect copies of the programs sold before the injunction goes into effect.
