They patented a very specific algorithm for a very specific kind of game. You can still do knock-offs of the system in the same way you can make RTS games without asking Blizzard’s permission or platformers without asking Nintendo’s.
I would suspect that SoM’s system is complex enough that nobody’s been eager to try and replicate it. But they high level concept of randomized enemy generation isn’t something you can patent. Neither is randomizing story elements between NPCs.
Digital Extremes was going to do something somewhat similar with their nemesis system in Warframe but had to scrap it because of that patent. So now we have the mediocre Lich/Sister/Boyband systems in place instead.
