• Scientific principles, abstract theorems, and natural phenomena

Explanation:

Patent law does not protect information or bare ideas. When a person holds patent over an idea or innovation, they have the authority to use, sell or exploit the subject matter of the patent. There are certain things that cannot be patented. Such includes mere scientific principles or abstract theorem that is common to everyone, phenomena that already exists in nature and also those inventions which are obvious to the knowledgeable in the relevant field. For one to obtain a patent, they need to prove that it is a new idea and which has already been embodied in a useful device.
