Sony Wins Patent Lawsuit Over PlayStation Controller Technology

A US District Court judge has ruled that Sony did not infringe on Genuine Enabling Technology's patent, closing a $500 million lawsuit.

Genuine Enabling Technology (GET) claimed Sony infringed on its patent for controller-to-console communication, seeking $500 million in damages.
The lawsuit, filed in 2017, focused on the method PlayStation controllers and consoles use to transmit signals for button inputs and motion controls.
Sony argued that its technology was not 'structurally equivalent' to GET's patented method, a point the judge agreed with, finding in Sony's favor.
The case has been officially closed, with the judge ruling that Sony did not infringe on GET's patent.
GET has an ongoing lawsuit against Nintendo for similar claims, which is still pending after a reversal in the US Court of Appeals in 2022.
