A patent infringement case about the technology in Wii and GameCube consoles has been dismissed by a US District Court judge.

The patent affected was listed as number 6,297,751, which reads as follows:

"The joystick port interface includes an integrated circuit receiving an analogue joystick position measurement signal and outputting a digital pulse signal to a processor which signifies a joystick coordinate value. The integrated circuit includes a pulse generator and a bidirectional buffer circuit.

"The bidirectional buffer circuit receives the analog joystick position measurement signal and selectively discharges an RC network capacitor which provides this analogue measurement. This implementation provides a joystick port which uses low-voltage CMOS VLSI structures which can interface a conventional high-voltage joystick with the processor."

The judge ruled against the infringement, and also decided there would be no need for a jury trial.
