Microsoft is taking a British peripheral manufacturer to court, alleging that the company - Datel - has "illegally copied" the publisher's own Xbox 360 control pad designs.
The case centres around two of Datel's third-party Xbox 360 control pads, the TurboFire and WildFire, which Microsoft claim infringe upon a "number" of patents governing its own, first-party peripherals.
It's unclear what, exactly, Datel is alleged to have ripped off, but you can see the TurboFire controller above and the official Microsoft Xbox 360 controller below. They don't exactly look alike, so the case must be focused on how the pads connect to the 360, something Microsoft has been notoriously protective of over the years.
