For applications filed on or after September 16, 2012:

  • An assignee or obligated assignee may file the application as the applicant
  • A person who shows sufficient proprietary interest may file the application on behalf of and as agent for the inventor
  • The applicant may file a substitute statement in lieu of an inventor’s oath or declaration if the inventor has refused to execute the oath or declaration

For applications filed before September 16, 2012, a petition under pre-AIA 37 CFR 1.47 could be filed.

MPEP 409.03(f) – Proof of Proprietary Interest outlines the requirements for establishing proprietary interest in a patent application when an inventor refuses to execute an oath or declaration. The section states:

‘If an inventor refuses to execute an oath or declaration under 37 CFR 1.63, the party to whom the inventor has assigned or agreed in writing to assign the invention, or who otherwise shows sufficient proprietary interest in the matter justifying such action, may make application for patent as provided in 37 CFR 1.46.’

What evidence is required to prove an inventor’s refusal to sign a patent application?

When an inventor refuses to sign a patent application, specific evidence is required to proceed without their signature. The MPEP 409.03(d) outlines the necessary proof:

‘Where refusal of the inventor to sign the application papers is the reason for filing under pre-AIA 37 CFR 1.47(b), the applicant should make reasonable efforts to contact the inventor and to secure the inventor’s signature.’

Evidence of refusal typically includes:

  • Documented attempts to contact the inventor (emails, letters, phone logs)
  • Any written responses from the inventor indicating refusal
  • Witness statements corroborating the inventor’s refusal
  • A detailed explanation of the circumstances surrounding the refusal

The USPTO requires a thorough statement of facts describing the situation and efforts made to obtain the inventor’s signature. It’s crucial to demonstrate that the inventor was fully informed about the patent application and explicitly refused to sign, rather than simply being unresponsive.

Determining refusal to join an application under pre-AIA 37 CFR 1.47 involves several considerations:

  1. The inventor must be presented with the application papers.
  2. The inventor must understand what they are being asked to sign.
  3. The inventor must expressly refuse to accept the application papers.

The MPEP states:

‘A refusal by an inventor to sign an oath or declaration when the inventor has not been presented with the application papers does not itself suggest that the inventor is refusing to join the application unless it is clear that the inventor understands exactly what he or she is being asked to sign and refuses to accept the application papers.’

It’s important to document the circumstances of the presentation and refusal, including time, place, and any written evidence of refusal.
