That said, it looks like one of the differences involves integrating the back button accessory of the DualShock 4. It lacks the bulk of an attached accessory, but it is functionally identical, with two pedal-like buttons at the back. It would appear that these two new buttons will be programmable, allowing them to perform the same function as any of the face or shoulder buttons.
Another minor difference between the controller depicted here and the one in the previous patent is the lack of the PlayStation button in the middle. Beyond that, there’s also the charging port on this new patent. While it’s not exactly a clear view, it seems to depict a Micro-USB port, rather than USB-C. Because of this, it may also be the case that the patent isn’t depicting a DualShock 5, controller, but rather a current-generation DualShock 4 variant. As is the nature of most patents, does not guarantee an eventual product. It’s also pretty confusing, considering the differences in detail between two patents of what might be the same thing. The integration of extra buttons at the back is certainly appealing, but we’ll see if they really show up when Sony officially announces the PS5 next year. (Source: WIPO via Polygon)
