This is a freaking great joke.....I just couldn't help laughing this news...
Here a small quote:
It sounds like a joke. But, it's real and it's anything but a joke for Microsoft. Judge Leonard Davis, of the U.S. District Court for the Eastern District of Texas, has issued an injunction (PDF Link) that "prohibits Microsoft from selling or importing to the United States any Microsoft Word products that have the capability of opening .XML, .DOCX or DOCM files (XML files) containing custom XML."
Microsoft had been sued by i4i, a collaborative content solution and technology company. Its founder, Michel Vulpe, owned a patent covering a way of reading XML (Extended Markup Language) documents. XML is the basis of Microsoft's controversial Open XML document formats. The U.S. District Court for the Eastern District of Texas is infamous for supporting patent lawsuits and fast-tracking them. In intellectual property law circles, this Court has become known as "A Haven for Patent Pirates."
