The criteria sought for patent-protected inventions are;
An innovation, meaning overcoming the state of the art and to have applicability to the industry. Innovation is an absolute innovation in the sense of being written, verbally or otherwise unexplained by others before the application is made.
The criterion for exceeding the known state of the technique is the "quality that the expert can not easily think and apply".
Applicability to the industry means that the invention can be applied to practice instead of being entirely theoretical.
Inventions bearing these three criteria are protected by patents.
