Sony saw a US district court judge rule that it did not infringe another company’s patents with its PlayStation consoles and controllers, something it was accused of by Genuine Enabling Technology in a lawsuit in which it demanded $500 million for damages allegedly caused by Japanese company.
Since 2017, GET has accused Sony of infringing its 730 Patent, in which it describes a method and apparatus necessary to produce a combined stream of data and its retrieval by movement on user controls.
At the heart of it all is the way PlayStation consoles communicate with controls, using a separate signal at a low, variable frequency to register button presses and another high frequency to register movement controls.
GET says that no controller could produce both frequencies and functionalities, which led it to create the technology in the patent it registered, but Sony claimed that the company was unable to unequivocally prove that the components in its controllers are structurally equivalent to the diagrams in your patent.
The judge agreed with Sony and, in addition to deciding that no concrete evidence had been presented, closed the case. Currently, GET is conducting this same battle in court against Nintendo.
