While PlayStation controllers can already be used alongside compatible Bluetooth-enabled mobile devices at present, the patent seems to suggest that the device would resemble something similar to third-party mobile controller grips such as the iPhone compatible Backbone One.
Sony's decision to seemingly take out a patent on a controller compatible with mobile devices may not come as a shock to many eagle-eyed fans of the company.
Earlier this year, Sony set to expand further into the realm of smartphones as it surfaced that the company was looking to appoint a Head of Mobile.
