How does the USPTO verify the authenticity of S-signatures?

The USPTO has specific methods to verify the authenticity of S-signatures:

1. Comparison with other documents: The USPTO may compare the S-signature with other signatures from the same person in their records.
2. Certification statement: MPEP 402.03 states: ‘The person inserting a permanent S-signature must present a statement certifying that the inserted signature is his or her own signature.’
3. Audit trail: Electronic filing systems may maintain an audit trail of who submitted the document.
4. Additional verification: In case of doubt, the USPTO may request additional verification or clarification.

While the USPTO generally presumes the authenticity of signatures, it’s crucial to ensure all S-signatures are genuine and properly certified to avoid potential legal issues.
