Fuckers patented the concept of a user interface device sending / receiving multiple streams of data at once?? Rgb keyboard/mouses, headphones with buttons on them.. so many things fall under that category.
It's incredible how broad the patent is. It's not about an implementation, as far as I can tell it doesn't even need to transmit the input it receives. By a stretch any display, multi channel audio setup or even the power button of a computer with a light on it would qualify.
Do they just let people write whatever they want on patents??
