Could be better than you think...

Since MS successfully claimed prior art to influence the final decision, one might consider it a victory for common sense.

Now anytime MS, RIAA, BSAA or any other multinational ogre tries one on, prior art can be cited (as long as it really exists, of course) as a valid defence.

And one's lawyer could cite Micosoft vs Eolas as a part of the case history.

Hoist with one's own petard, n'est pas?
