An inventor is a person who creates or discovers a new method, form, device or other useful means that becomes known as an
invention. The word inventor comes from the
Latin verb invenire, invent-, to find.
 The system of
patents was established to encourage inventors by granting limited-term, limited
monopoly on inventions determined to be sufficiently
useful. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers nor scientists.
