On July 4, a Twitter user going by Renka_schedule posted notes and images stated to come from a previously un-announced Sony patent. The diagram, which is labeled in Japanese, shows games for the PlayStation 1, 2, and 3 consoles being stored in a library and emulated onto separate screens.

The information accompanying the patent, which is also in Japanese, describes the games being stored in a cloud-based library and then played via a virtual machine. A translation states:

"A large number of game titles across PS1/PS2/PS3 and various generations of game consoles can be stored and used via the cloud gaming library. These games can be run on a virtual machine that mimics the operating system associated with each game console."

This patent, if it enters development and sees eventual release, could be extremely beneficial for fans of classic PlayStation titles. It could allow gamers to play favorite installments from the first three consoles in Sony's popular series without needing to own physical versions of all three.

Later in the same thread, Renka_schedule showed off yet another potential patent from Sony. This one shows players gaining the ability to record scenes from their own gameplay and sharing it with their friends via uploading it to the cloud. It is rumored to be connected to the "Create" button, which will be featured in the new DualSense Controller releasing alongside the PlayStation 5.

The presence of these patents does not necessarily mean that these products will ultimately be produced. This is just a sign that Sony is researching these ideas and looking into potentially developing them. So, as of now, gamers should not treat these patents as any definitive proof of future PlayStation innovations.

Currently, the upcoming PlayStation 5 console is speculated to be backwards compatible with a majority of PlayStation 4 titles. However, no information regarding backwards compatibility with the PlayStation 1, 2, or 3 has currently been confirmed.
