A patent protects a practical solution to a technical problem
A patent can only be granted for an invention.
In order for an invention to lead to a patent it must constitute a practical solution to a problem where the solution is of a technical nature or effect and is reproducible.
You can not be granted a patent for an idea without describing or showing how the solution works in practice. You can not get a patent for a business concept.
Processes, products and devices can be patented, for example blood analyses, computer technology and zip fasteners:
