I'm surprised no-one mentioned Mark Monitor[0] (no affiliation). A lot of big brand corporations use it to protect their intellectual property. Can you imagine, for example, someone getting their hands on `apple.com` or `icloud.com`. They could wreak havoc since a lot of iDevices use those two domains in order to function and you could pwn many devices if you were determined enough. I imagine MM solves the 10-year time window problem by ensuring the domain lives well on into the future. It's what they do.
