   Legend has it that Douglas Engelbart invented the mouse in 1968.

   But did you know that German television manufacturer Telefunken released a "rolling-ball" device just a few months earlier?

   From a technical perspective it actually closely resembles the kind of mouse that we ended up using until the late 90s.

   The German patent office declined a patent due to a "lack of inventive step".
