Who will be the inventors?
Unlike authorship of scientific publications which may include a person as author because he/she made a substantial contribution to the findings, or for professional courtesy, inventorship is legally designated. An incorrect declaration of inventorship may jeopardize the validity of a granted patent. The threshold question in determining inventorship is who conceived the invention. Unless a person contributes to the conception of the invention (the mental act of thinking of the idea of the invention and how it would be implemented in sufficient details), he/she is not an inventor.
