Microsoft patent filing is stupid rather than evil

Many years ago, during a press visit to Microsoft HQ in Seattle, I was given relative freedom to wander around the Redmond campus. Of course, there were some areas that were strictly out of bounds. Areas like the one which was entered via the 'Cryogenics Lab' door for example. At the time I thought it a little odd that Microsoft should be investing in cryogenics, but wrote it off as the kind of thing you can get your company to play with when you are the richest man on the planet.
