Adobe CEO Bruce Chizen told German-language newspaper Euro am Sonntag that his company is prepared to battle Microsoft in court over some of Vista's new features, a threat we have heard before. Chizen said that the inclusion of Microsoft's new XML Paper Specification (XPS) in Vista and Office 2007 leaves Adobe with two options. "[Adobe can] sue Microsoft directly, or work together with the regulatory authority [the European Commission] and provide them the essential information," said Chizen. "We will do the latter, then we will wait and see."

Microsoft's XPS is a new document format that will be supported in both Vista and Office 2007. When Microsoft first announced XPS, Adobe cried "foul" to the EC. Adobe's protestations backfired when Microsoft responded to the EC's concerns by submitting XPS to a standards-setting body while ensuring that its licensing terms are compatible with open source licenses.
