Cognex Corporation is an American corporation that manufactures commercial machine vision systems. Cognex is the world leader in its field, boasting an impressive array of patents and academic experts.

In 2004, the company won an intellectual property victory, when a judge ruled in Cognex s favor in a long standing patent lawsuit brought against the estate of the self-styled inventor Jerome H. Lemelson, who had filed dozens of submarine patents, some of which purported to cover machine vision processes.
