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.
