Court Bans Sale of Word; Microsoft Promises Fix

But people looking to buy Word or Microsoft's Office package in the U.S. won't have to go without the software. Microsoft said Tuesday it expects that new versions of the product, with the computer code in question removed, will be ready for sale when the injunction begins on Jan. 11.

Toronto-based i4i Inc. sued Microsoft in 2007, saying it owned the technology behind a tool in the popular word processing program. The technology in question gives Word users an improved way to edit XML, or code that tells the program how to interpret and display a document's contents.

A Texas jury found that Microsoft Word willfully infringed on the patent. Microsoft appealed that decision, but the U.S. Court of Appeals for the Federal Circuit on Tuesday upheld the lower court's damage award and the injunction against future sales of infringing copies of Word.

Michel Vulpe, founder and co-inventor of i4i, said in a statement that the company is pleased with the decision, calling it "an important step in protecting the property rights of small inventors."
