Sony has applied for a patent for its Back Button Attachment, the add-on accessory for the DualShock 4 announced back in 2019 that adds programmable buttons to the underside of the controller. The filing, spotted by
IGN, doesn’t call the device by its existing name, but rather describes the product as an add-on with buttons that “may be mapped to controller buttons using customized button mapping pre-sets” and features a number of diagrams showing off how it works.
It’s not immediately clear what the patent application means for Sony. The application, which has not yet been granted, was first filed in the US in the summer of 2019, before Sony filed it internationally in June of last year. It offers no indication this device could be coming to the PlayStation 5’s DualSense controller, as the diagrams depict what looks to be an older DualShock 4 device and do not describe any corresponding functions with the new console’s gamepad or any of its unique features.
