The IBM bullet dodging patent story, which originally broke on this blog after being discovered by reader Daniel E. Watters, created quite a lot of noise on the internet.
Noah at Danger Room noticed that the patent has since been withdrawn. It seems odd to go to all that work writing a patent, paying lawyers, only to withdraw it after news of its existance hits the internet days later. Anyone know if this happens frequently?
The lesson here is that you cannot deleted stuff off the internet, someone, somewhere, has a copy.
