The Five Levels of Inventions- A Classification of Patents from TRIZ perspective

Author: Umakant Mishra

Abstract:

The Five levels of Inventions is a popular concept in the study of TRIZ. Generally patent databases (like USPTO) classify inventions according to their topics or areas of invention. But they don’t classify inventions according to their easiness or usefulness or inventiveness. Altshuller classified patents into five levels according to their levels of inventiveness. The higher levels of inventions are difficult (and rare) while the lower levels of inventions are easy and plenty in number. This article attempts to explain the five levels of inventions in simple terms and the purpose behind such a classification. Although there are limitations and criticisms to these classifications, anybody will agree to the fact that there do exist a difference in the inventiveness between two different solutions.
