This is designed to work with all games so it's more similar to how many emulators implement quick save than how it works in most games. I suspect or rather hope that it's as fast (instantaneous) as it is in emulators.
It also appears that it's supposed to rewind like you can do in some racing games.
It's more complicated than a simple quick save button found in mostly older games. It's a neat feature but I would obviously prefer that they didn't get the patent so Xbox also could implement something similar.
Sounds like something only a small number of devs would implement. Unless they are confident they can fuck with the memory space of all games without issues. I expect a PS5 game is a bit more complicated than a saved state on an SNES.
This needs to be killed as we have prior art (Emulators, Braid, Prince of Persia: Sands of Time, heaps of racing games, etc).
If their only significant addition is "we a have a button for it" then we need to ask if a button qualifies as "inventive" in 2024?

In emulation if you are using retroachievements rewinding / save stating gives you a 'lesser' achievement so the precedent is there from the groups that already invented such a thing
Is a crappy situation but patents don't enable the patent holder to make a product, after all you can make the product without claiming a patent. Instead they stop people who are not the patent holder from making that product.
So if we put on our tinfoil hats its likely that some "just in case" patents are really just stopping their competition from heading in that direction.
Their lack of a patent for controller vibration prevented Sony from having vibration on Sixaxis - notice that despite all the BS that it interfered with motion sensing, Dualshock 3 came out just a few months after Sony managed to settle the suite with Immersion.
Since there's no penalty for making a patent and not using it, it's probably cheaper for Sony to pre-emptively register everything that comes from brainstorming sessions.
