Sony is trying to patent its Back Button Attachment accessory for the PlayStation 4’s DualShock 4. Back in 2019, the company launched a programmable button attachment that connects to the underside of the controller. The gaming giant doesn’t give the patent a name and refers to it as an add-on with buttons that âmay be mapped to controller buttons using customized button mapping pre-sets.â It also offers a few diagrams showing how it works.
Sony filed the patent in the U.S. in the summer of 2019 and internationally with the World Intellectual Property Organization (WIPO) in June of 2020. With this in mind, this isn’t necessarily an indication that the accessory could be coming to the PlayStation 5’s DualSense controller. For example, the gamepad in the diagram shows off what looks to be a DualShock 4, and it doesn’t describe or mention any of the features available with the more recent controller.
