I hate MS and would liked to see them paying the $521 million... but that's better for software ;) MS has sometimes done good things. Even when IMHO they have done more evil than good, my congratulations for this task. MS has defended the software even when they did it only for their own goals. It's fine if it finishes fine ;)
Don't get all excited. They have a long way to go in the process unless Eolas doesn't file a response. In a lawsuit, one of the first steps the defense usually takes after being served is file a motion to dismiss. In patent reviews, one of the first things the patent office often does is reject the claim. This tests how serious the applicant really is, forces him to produce more info and stick with the long process which usually takes years to complete. It took the patent office about 4.5 years to approve this patent. IMO if Eoloas meets filing dates, the patent office's final decision to uphold or reject will drag out for quite awhile.
