A new PlayStation patent suggests that PS5, and possibly PS4, finally obtain compatibility with previous versions of PS3, PS2 and PS1. Unlike Xbox Series X, which reproduces many original Xbox 360 and Xbox games, PS5 only plays PS4 games and, of course, also PS5 games. It is not recompatible with PS3, PS2 or PS1 games. The unique architecture of the PS3 gives Sony an excuse when it comes to the Third Generation PlayStation console, but it is not clear why PS2 and PS1 are excluded. That said, it seems that much of this, if not all this, can finally remedy only.

A new Sony Interactive Entertainment patent has appeared online. And who is behind the patent? Mark CERN, the mastermind behind the PlayStation hardware. And what is the patent for? Well, it is titled Compatibility with earlier versions by using false clock and fine grain frequency. In summary, PlayStation is working in compatibility technology with previous versions, presumably to unlock PlayStation consoles inherited in the PS5 and perhaps in the PS4.

There is nothing in the patent that suggests that it has something to do with enabling compatibility with previous versions for PS3 games or PS2 games or PS1 games, but that is, of course, what everyone else thinks.

The unfortunate reality is that Sony constantly requests patents, many of which never exceed the conceptual stage. Over the years, a wide range of pending PlayStation patents has appeared online, and nothing of them has come out. This is true not only for Sony patents, but also for patents in general.


At the time of publication, Sony has not addressed any of this in any way, and we do not expect this to change. He never comments on patents or speculation they create. However, if you exceed expectations and break your constant silence, we will make sure to update the story accordingly.
