Independent inventor

An independent inventor is a person who creates inventions independently, rather than for an employer.
Many independent inventors patent their inventions so that they have rights over them, and hope to earn income from selling or licensing them. Usually inventions made in the course of employment are ultimately owned by the employer; this is often specified in the terms of employment. Other inventors (independent or corporate) may create inventions hoped to be of use to anybody, and place them in the public domain.
