Patent Ownership Inventors and Assignees


Inventors must be identified:

  • U.S. patent laws require the identification of all individual inventors.

  • Failure to name an inventor, or naming a non-inventor as an inventor, can invalidate any patent that might issue from an application.

  • There is no legal significance in the order in which inventors are named.

 What makes someone an inventor:

  • Only persons who contributed to the conception and/or the conversion of a conception to a practicality are inventors.

  • Persons who contribute financing or marketing or other auxiliary assistance only are not inventors.

 Assignment and ownership:

  • Persons or businesses can acquire an ownership interest in a patent application by assignment from the inventor.

  • The inventor granting the assignment is an assignor.

  • The person or business receiving the assignment is the assignee.

  • An inventor can assign a co-ownership interest by assignment to himself/herself and a non-inventor jointly.

  • The granting of such ownership or co-ownership rights should never be attempted by misjoinder of persons as inventors when they are not.

  • A patent application is owned by the inventors if there is no assignment.

  • Joint inventors-owners of a patent application hold their rights as tenants in common, not joint tenants.
