What are the requirements for filing a patent application when one joint inventor is unavailable?

When filing a patent application with at least one unavailable joint inventor under pre-AIA 37 CFR 1.47(a), the following requirements must be met:

  • All available joint inventors must make an oath or declaration for themselves and on behalf of the nonsigning inventor.
  • Proof must be provided that the nonsigning inventor cannot be found or refuses to execute the application.
  • The last known address of the nonsigning inventor must be stated.

As stated in MPEP 409.03(a):

“An application deposited in the U.S. Patent and Trademark Office pursuant to pre-AIA 37 CFR 1.47(a) must meet the following requirements: (A) All the available joint inventors must (1) make oath or declaration on their own behalf as required by pre-AIA 37 CFR 1.63 or 1.175 […] and (2) make oath or declaration on behalf of the nonsigning joint inventor as required by pre-AIA 37 CFR 1.64.”
