As I understand it, Commodore-Amiga held a patent that covered the opening up of a "Drop down menu" when the right mouse button is held down.
Apple were unaffected since they didn't use a right mouse button, and M$ used context sensitive menus that only required a right click rather than the button to be held down... thus the patent was pretty useless... except against AROS and MorphOS... but it expired years ago.
