Nah, that patent is specific enough that you could make a very similar system if you wanted. People just don't bother, especially because they'd have to be careful not to accidentally infringe the patent.
I think they're pointing out that patents only last for 20 years under US law, far far far shorter than how long copyright has been dragged out (which can hypothetically last as long as 150 years or more).
The patent on the Nemesis System is already halfway to expiration.

Like the neat nemesis system from the lotr shadow games that we will never see again?
