Where was he years ago when this sort of 2-factor auth was starting to get popular? Don't you have to actively defend your patent? Sitting on it for 15 years and then deciding to sue on a whim can't look good in a court's eyes... |

No, you don't. You may be thinking of trademarks, which you do have to defend or license to avoid dilution.
You may say that this is a problem with the patent system. But here on HN, we already know how broken the patent system is, don't we?
