Of course I know,this is not the right place to ask this question. But I'm asking this,because i dont find any other good place.I wanna use the technology of the optical mouse and infrared keyboard (Yes!both are virtually same technology)in my project. Which part i want to use is, the sensing part of mouse and infrared keyboard (yeah! people call it sensor).Can I do that? or any other patent will stop me from doing this??
