What should I do if there are variations in my signature on different patent documents?
If there are variations in your signature across different patent documents, you should:
- Try to use a consistent signature for all patent correspondence to avoid confusion.
- Be prepared for the USPTO to require ratification or confirmation of the signature if there are significant variations.
- If asked to ratify, state that you personally signed the previously submitted document and, if needed, submit a compliant format of the signature.
According to the MPEP: “For consistency purposes, and to avoid raising a doubt as to who has signed, the same S-signature should be utilized each time, with variations of the signature being avoided.”
If the USPTO requires ratification, they may ask you to submit a statement or a duplicate document with a compliant signature. This helps ensure the authenticity of signatures and clarity of the record.
