M$ Fears Disclosure
Have you ever wondered why M$ has failed to meet the EU's demands for disclosure? The biggest problem M$ will have in a patent fight is that they will be forced to revel their own code base. We know from the last 20 years that M$ freely lifts what it wants from any source to get ahead, Stacker in the 90's for compression, BSD for the XP code base. Any lawsuit would open a Pandora's box of revealing the extent of outright theft that M$ has engaged in to get ahead since they could be forced to open their development records and any 'prior art' they may have forgotten to mention to get their patents.
