As the title says: Can an inventive step for an electronic based product be shown in a mere block diagram?
I have an idea for a product and the components are a tablet or phone (on one side) and an Arduino microprocessor (on the other side).
If a block diagram was drawn up, showing how the product worked in block diagram form, could the block diagram be sufficient to show the inventive step required for patentability?
In the particular circumstances where there is not a working model of the thing described in the block diagram. Only it being assumed the engineering required (software and hardware) is likely fairly straight-forward to accomplish, along with signals, outputs and inputs marked on the block diagram.
