As revealed in a thread on Reddit, it looks like the patent in question was originally filed in 2012.
While the patent mentions veteran video games developer David Perry, who co-founded the firm Gaikai whose tech ended up being used on the PlayStation Now service.
PlayStation Now offers streaming for PS2, PS3 and PS4 games – so this patent could just be detailing the way emulation is already used in PS Now.
We’ll have to wait to find out for sure though, and PS5 fans could find out for certain either way soon.
Sony are rumoured to be prepping a State of Play event for August which will reveal more details on the PS5.
If the PS5 does indeed offer a wide range of backwards compatibility then that could get confirmed during the upcoming State of Play next month.
