U.S. patent law elevates the importance of “the inventor” to an extent unseen in the rest of the world. Unlike many other countries, ownership of patent applications in the United States initially vests in the inventors listed on the application.
Authorship is the currency of academia, and principle investigators are often generous with technicians and collaborators when listing authors on a paper. However, the identification of an “inventor” has legal significance in the U.S. and cannot be applied to those who have not made an inventive contribution.
