I've created a wireless parking space sensor using a specific microcontrollermicro-controller and other components. I'm sure the same components used can be utilized in a different manner by others just with a change of firmware so I was wondering:
What exactly is patentable?
Would it be the combination of components with dimensions of PCB board?
Would it be just the firmware programmed on the microcontrollermicro-controller?
Would it be the specific purpose for the combination of components and firmware?
