What are the guidelines for demonstrating inventions during patent examiner interviews?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

When demonstrating inventions during patent examiner interviews, applicants should follow these guidelines:

• Safety first: Ensure the demonstration is safe for all participants.
• Advance notice: Inform the examiner in advance about any special arrangements needed.
• Time management: Keep the demonstration brief and focused on relevant aspects.
• Documentation: Provide a written description of the demonstration for the record.

The MPEP 713.08 states: The demonstrations may be presented in conjunction with the interview or at a later date. This flexibility allows applicants to choose the most appropriate timing for their demonstration.
