Seems we just got through one bothersome bit of news when another comes along. All 3 game console makers are being sued by Fenner Investments over an alledgedly infringed-upon patent. The patent in question is #6,297,751 for a "low-voltage joystick port interface."

The patent in question was filed in 1998 and awarded in 2001. It is described as "a low power port which interfaces a typical 5 Volt joystick peripheral device with a lower power computer port. The low-voltage joystick port interface includes a bidirectional buffer circuit and a pulse generator which, together, generate a digital pulse signal, representing a joystick coordinate position, based on an input analog measurement signal."

A Google search for Fenner Investments doesn't dig up much more information other than a couple ofother lawsuits fr other patent infringements. Still considering how long the companies have been in the biz I'm thinking this one may come to a better conclusion than that one versus Immersion Technologies regarding the rumble.
